Angioblast: it is derived from the cardiogenic plate, and first appears in an embryo with 3 somites. It is fundamentally bilateral in origin, and at very early stage are the two sides anastomosed with each other in the cranial region. Myocardium: it is formed from paired cardiogenic folds. There can not be noted any distinct demarcation on the surface of the myocardial tubes before they are fused together. The folds are first fused at the middle part in the 7 - 8 somite stage, and the fusion is completed in the 12 somite stage. Mesocardium: the ventral mesocardium first appears in the embryo having 6 - 7 somites, and ruptures at its middle part in the 8 - 9 somite stage. Its remnant is observed in still later stages, namely, we can find it in an embryo with 12 somites. The dorsal mesocardium formes between the 9 and 10 somite stages, and rupture between the 15 and 18 somite stages. Endocardium: it is formed from angioblasts. It has the endothelial character in the 5 - 6 somite stages, and the paired tubes are derived from it in the 9 somite stage. The endothelial tubes unite in the bulbar and the ventricular region. From the network of angioblasts which are spread at the cranial portion of the embryonic shield from which a pair of aortic arches are derived. In the bulbar region, the right endothelial tube markedly exceeds in caliber that of the left side. The latter atrophies and disappears, and the former makes the genuine bulbus cordis. Caudally, on the contrary, the left tube exceeds that of the right and the former is situated sinistro-ventrally to the latter. In the 13 - 14 somite stages the fusion of the paired tubes is almost completed, and the ventricle and atrium may be distinguished by the atrioventricular constriction. In closing, I wish to express my cordial thanks to Prof. Dr. J. Shikinami for his kind criticism and advice.</P>

In dem voritgen Kapitel habe ich an Hand von Wachsmodellen die Morphogenese und Entwicklungsegeschichte des Pankreas stadienweise an einem in Japan einheimischen Vogel, Uroloncha domestica Flower, in allen Einzelheiten betrachtet. Somit habe ich nunmehr die hauptsaichlichsten Resultate der vorliegenden Untersuchung zusammenzufassen und mit den bei der Haustaube erzielten Befunden zu vergleichen. Wenn meine Untersuchungen auch nur zwei, aber im merhin typische Vogelgattungen urnfassen, so vermogen sie dennoch neues Licht auf die Entwicklung der Anlagen des Vogelpankreas und ihr Verhaltnis zu den benachbarten Organen zu werfen. Die erste Anlage des dorsalen Pankreas bei den Vogeln wird von den einzelnen Autoren verschieden beschrieben. Das jungste Stadiun der dorsalen Pankreasanlage bei meinen Tieren stammt von einem Embryo mit 28 Ursetgmenten (Stadium 3). Die erste dorsale Pankreas anlage tritt in diesem Stadium als eine charakteristische umschriebene Wucherung des primitiven Epithels der dorsalen Daunrinne auf. Die Abgrenzungo der eigentlichen dors.alen Pankreasanlage vom ubrigen Entoderm ist, besonders in diesem juntgsten Entwicklungsstadium, nicht ganz leicht. Die Oberflache der Anlage ist etwas uneben, aber die Niveauunterschiede sind gering. An den Haustauben finde ich die erste dorsale Pankreasanlage bei einem Embryo mit 26 Ursegmenten, und ihr erster Erscheinungszustand ist fast der t:gleiche. So stimmt mein Befund in Bczug auf Ort und Stadium des ersten Auftretens des dorsalen Pankreas unogefahr mit dem von mir bei den Haustauben gemachten uberein. Ein tuberblick tuber die Literatur zeigot uns, wie wenig wir uber das erste Auftreten und die ersten Umbilclungasvorgange der ventralen Pankreasanlagen wissen. Es war daher fur mich interessant, diese Frage einegehend zu verfolgen und dabei einige neue Tatsachen zu finden, die fur die Entwicklungsgeschichte der ventralen Pankreasanlagen der Vogel von grosser Bedeutung zu sein scheinen. Die wirklich ersten Entwicklun:gsstadien der ventralen Pankreasanlagen finde ich bei meinen Tieren zu einer Zeit, wo sich bei ihnen das 29. -31. Paar von Ursegmenten entwickelt. Niemals treten die rechte und die linke Anlage gleichzeitig auf, sondern stets ist. eine alter als die andere, manchrnal ist es die linke, manchmal die rechte. Auch kommt es vor, dass bei jtingeren Embryonen die ventralen Pankreasanlagen weiter entwickelt sind als bei alteren Embryonen. Bei einem Ernbryo mit 30 das eine Andeutung von der Bildung kleinster divertikelartiger Ausstulpungen gibt, Bei den Haust,auben fand ich die erste ventrale Pankreasanlage an einem Embryo mit 35 Ursegmenten schon als kleinste clivertikelartitge Ausstulpungen von den Seitenwanden des primitiven Duodenums, da die Dottervenen dem Darrnepithel am nachsten liegen. Bei den Vogeln blieb die Fraoge nach dem Vorhandensein zweier ventraler Pankrease bis auf die junboste Zeit, unentschieden ; die kurzlich erschienene Arbeit von Brouha machte das Vorhandensein zweier ventraler Pankrease beim Hiihnchen nur wabrscheinlich ; sicher bewies dann erst Choronshitzky diese Tatsache. Bei den Haustauben wurde von mir schon die Einheit bestimmt,. Und auch hier stellte ich gleichmassing bei meinen Tleren das Vorhandensein zweier ventraler Pankrease fest,. Die dorsale Pankreasanlage tritt im Stadium 5 (Embryo mit 30 Ursegment,en) zum ersten Male als eine wirkliche, rinnenformige Ausstulpung der dorsalen Darmrinne hervor. Das nachstaltere Stadium (Stadium 6) der ventralen Pankreasanlatge finden wir bei einem Embryo mit 31 Ursegmenten. Zwei kleine, fertige Divertikel sind schon verhaltnismassig leicht als eine solche zu erkennen und abzugrenzen. Die linke ventrale Anlaoge ist etwas mehr kranialwarts gelegt als die rechte, und die Neigung der linken, sich kaudalwarts, der rechten, sich kranialwarts zu entwickeln, wird in den nachsten Stadien 7, 8, und 9 immer auffallender. Bei den Haustauben fan ich aber diese Neitguntg nicht, sodern sah beide ventralen Anlatgen sich mit der Drehun g des Duodenums kranialwarts entwickeln. Dieser Unterschied ist von grosser Bedeutuntg fur die weitere.Fortentwicklung der ventralen Pankreasanlagen. Die dorsale Pankreasanlage in den Stadien 8 und 9 entwickelt sich gut, und ich konnte den knolligen primitiven Drusenkorper, den primitiven Ausfuhrungsgang und Zwischenstucke unterscheiclen. Gleichzeitig be merkte ich zwischen beiden ventralen Anlaogen die Gallenblase in voller Entwicklung. Au den ausogewachsenen Haustauben fehlt die Gallen blase nur bis zu der Zeit, wo die kauclale Leberanlage bemerkt wird. Bei meinen Tieren geht ein Leberganog direkt zum Duodenum, wahrend der andere Lebergang als Ductus hepato-cysticus in die Gallenblase mtindet, die selbst wiecler durch den Ductus choledocus in das Duode num fuhrt. Den nachst.folgenden Entwicklungszustand der ventralen Pankreasanlagen finde ich bei den Stadien 10 und 11. Die schon, wie im vorigen Kapitel erwahut, deutlich ausgesprochene Abschnuruntg von der Darmwand ist noch weiter vortgeschritten und hat den Wurzelteil der Anlage vollkommen von der Darmwand getrennt. Daher konnte ich den primitiven Drtisenkorper und den primitiven Ausfuhrungsgang unter scheiden. Beide Offnuntgen liegen in der Tiefe einer gerneinsamen, zwischen dem primitiven Duodeuum und dem primitiven Choledocus gelegenen Grube. Die Drusenkorper der beiden ventralen Pankreasanlagen entwickeln sich, besonders die rechten, dorsalwarts auffallend und nahern sich den dorsalen Pankreasanlagen. Die dorsale Anlage wachst auch in diesen Stadien dorsokaudalwarts und zeigt deutliche Drtisenschlauche. Ich beobachte hier auch eine Verkleinerung der Verbindungsbrucke zwischen Darm und dorsalem Pankreas. Die dor sale und die rechte ventrale Pankreasanlage sind im nachsten Staclium 12 miteinander vollstandig verschmolzen, und auch die linke ventrale Anlage nahert sich ihnen dicht. Zur Zeit der Vereinigung der dorsalen mit der rechten ventralen Anlage zeigt sich eine immer deutlicher werdende Abschnurung der Pankreasanlage, wo der Ausftihrungsgang mit, dem Darme zusammenhangt. Bei den Haustauben fand ich die dorsale Pankreasanlage mit der ventralen Anlage zuerst vereiniegt am Embryo von 6.5 mm Scheitel-Steiss-Laloge, und dann beide vollstandig verschrnolzen am Embryo von 12.0mm Scheitel-Steiss-Lange. Die weitere Entwicklung der Pankreasanlagen soll aber nicht Gegenstand dieser Abhandluntg sein.

In the present observation, 61.4% of C58 mice developed leukemia spontaneously after the latent periods varing from 4 to 19 months. In non-leukemic mice, blood counting, peripheral-blood picture and myelogram did not show any significant change throughout the each age groups, but lymphocyt/neutrophile ratio decreased gradually after the age of 6 month. Old mice above 12 months of age showed a slight hypochromic anemia and relative neutrophilia. Most of the spontaneous leukemia occurred after the age of 6 month and 61.4% of them occurred between the age of 12 and 16 month. All of the spontaneous leukemias observed in this strain were lymphatic type. White cell count ranged from 4,500 to 225,000, averaging 109,600 with 47.2% lymphoblasts in average. Marked anemia and thrombocytopenia were present. Myelograms showed slight or moderate lymphoblastic infiltrations, but impressed preparation of spleen and lymph node always contained lymphoblasts over 90%. Morphological characteristics of the lymphoblast observed in spontaneous leukemia were narrow basophilic cytoplasm, large nucleus with a few deep indentations, coarse chromatin net work and nucleoles of vague chromatin borders. Phase contrast microscopy of lymphoblast showed nucleal indentations clearly and bright cytoplasm with a few rod-shaped mitocondrias in the Golgi area. Electron microscopic observations of lymphoblast also revealed the characteristic indentations of the nucleus. Spontaneous leukemia could be transplanted easely to the adult C58 mice by cell graft. A transplanted line named OHS-LL, No 1 is being maintained serially up to present. Serially transplanted leukemia mice often showed remarkable myeloid reaction and died after 7-8 days after cell graft. Blastic cells became to show atypical form suggesting of much more primitive and malignant character than that of the original leukemia by serial transplantations. Electron microscopic observations of lymph node and spleen of spontaneous leukemia revealed the presence of numerous virus particles located extracellularly. These particles were morphlolgically identical with the C particle observed in various other leukemic mice. en-copyright= kn-copyright= en-aut-name=SuzukiShinya en-aut-sei=Suzuki en-aut-mei=Shinya kn-aut-name=鈴木信也 kn-aut-sei=鈴木 kn-aut-mei=信也 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=875 end-page=880 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On the Mitosis of the Cultured Cell Infected with Canine Distemper Virus kn-title=ジステンパーウイルス感染培養細胞の有絲分裂像について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present paper will report about the mitotic phases of the cells infected with canine distemper virus.

As a result it has been found that in melancholia 17-KS fraction in urine is. decreased while serum 17-OHCS fraction is increased. Moreover, since the administration of androsterone or its series improves general conditions in melancholia and ACTH injection or cortisol medication aggravates the conditions, it is assumed that the decrease in sex hormones is responsible for the development of melancholia. 3.

Proliferation capacity of adenovirus 12 in hamsters of different age kn-title=Adenovirus 12型に関する研究 第V編 年令別ハムスターに於ける Adenovirus 12型の増殖性について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Since the discovery that adenovirus type 12 inoculated into newborn hamsters develop tumor in a high percentage of the animals, other types 18, 7 and 31 were also found to induce tumors to a lesser extent. In the elucitaion of the mechanism of carcinogenesis due to virus the study of changes in virus growth appears to be most important. For this reason, adeno-virus type 12 was inoculated to hamsters ranging in age from newborn to 14, 45 and 65 days old. These animals were sacrificed at diffe ent time intervals after the inoculation, and the kidney, liver, peritoneum and lung were removed, and examined for virus. For the detection of virus in these organs, the method of s'ant agar culture was employed as it was found to be simple and easy to manipulated, as reported previously. As a result it was found that: 1. In the inoculation of this virus to newborn hamsters, the virus could be isolated from various organs up to l1 days after the inoculation. In this instance, the virus was found to be most active in the organs 1-7 days after the inoculaticn, indicating some proliferation of the virus. 2. With the hamsters 14 days old, it was possible to isolate the virus for 3 days after the inoculation. 3. In the case of animals 45 and 65 days old, the virus disappeared within 24 days of the inoculation. 4. In the inoculation of the virus to newborns, the tumor growth was noted at autopsy 30 days later, while no tumor could be observed in those animals over 14 days old. en-copyright= kn-copyright= en-aut-name=FujitaKozo en-aut-sei=Fujita en-aut-mei=Kozo kn-aut-name=藤田耕三 kn-aut-sei=藤田 kn-aut-mei=耕三 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部微生物学教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=857 end-page=860 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Adenovirus Type 12 2.

After infecting the cells with virus, the tissue cultures were conducted by the slant agar and monolayer methods, to compare the degree of virus proliferation for successive generations in each experimental group. The results of the study are summarized as follows. 1. When HeLa S(3) cells were infected with minute quantities of virus for successive generations (30 days each generation), the virus proliferation, as determined by cytopathic effect (CPE), was better in the case of the slant agar culture than in the monolayer culture. 2. Similar cultures were conducted by two methods in which the culture period was changed to 7 days or 30-35 days for each generation. As a result it was found that the proliferation of the virus could be detected only at the fifth or sixth generation in all the experimental groups. Both the slant agar culture and the monolayer culture of infected HeLa-S(3) cells gave the results similar to those obtained in the successive cultures conducted by the freezingthawing method (reported in Part 1). kn-abstract= en-copyright= kn-copyright= en-aut-name=FujitaKozo en-aut-sei=Fujita en-aut-mei=Kozo kn-aut-name=藤田耕三 kn-aut-sei=藤田 kn-aut-mei=耕三 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部微生物学教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=849 end-page=855 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Adenovirus Type 12 1. The tissue culture of adenovirus 12 by three methods kn-title=Adenovirus 12型に関する研究 第T編 Adenovirus 12型の3種の組織培養法による増殖性について en-subtitle= kn-subtitle= en-abstract= kn-abstract=It is known that adenovirus type 12 nduces tumor in a high proportion of young hamsters, and also other types of adenoviruses do so to some extent. In the study of this virus the problems are posed the survival of the virus inoculated in animals, the presence or absence of the virus in the tumor developed by the virus, and the isolation of virus from man. It is, therefore, necessary to find out some appropriate methods to detect even a minute quantity of virus. With this view in mind, the authors conducted a series of experiments by the following three methods of successive tissue cultures using monolayer HeLa cells in culture infected with adenovirus 12 for the period of 7 days for each generation to see which of the three methods is most suitable. The results of this study are briefly summarized as follows 1. The tissue culture conducted for generations of HeLa cells with freezing-thawing techniques: The cells growing in monolayer in the test tubes were infected with adenovirus type 12 and cultured for 7 days as one generation. At the termination of each culture period the medium was changed with 1ml of fresh one. The first generation cells were frozen and thawed, cent-rifuged, and then the supernatant was placed into new monolayer HeLa cells. Subsequently, tissue culture was continued for generation after generation. In the doses of 1, and 10(-1) TCID(50) of virus used, 3 generations were needed to confirm proliferation of virus on the ground of cellular degeneration, and in the doses of 10(-2), 2×10(-3), and 10(-3) TCID(50), 4 generations were needed. 2. Virus culture through successive generations of infected cells: As in the preceding experiments the infected HeLa cells were cultured for 7 days, and after dispersing the cells in monolayer with trypsin solution, this first generation was divided into two equal parts, each of which was placed in the test tubes and cultured. Successive cultures were conducted in similar manner. The growth rate of virus in this series proved to be about the same as in the foregoing experiments. 3. Virus culture on slant agar: As in the preceding experiments the infected HeLa cells cultured for 7 days were dispersed with trypsin solution. This cell suspension of the first generation was centrifuged and the sediment, divided into about five equal masses of cells, was placed on slanted surface of agar, and cultured. Then one half the amount of the cells growing on the agar for 7 days was cultured again on the agar. The other half of the sediment was frozen-thawed with 1ml of the medium, centrifuged, and the supernatant was placed in the new monolayer to determine the proliferation of the virus. This method also gave the results not so different from those by the two preceding methods. From these results it is concluded that the tissue culture conducted on the slant agar is the most suitable method for the detection of virus growth because it is easy to manipulate and simple to maintain successive generations. en-copyright= kn-copyright= en-aut-name=FujitaKozo en-aut-sei=Fujita en-aut-mei=Kozo kn-aut-name=藤田耕三 kn-aut-sei=藤田 kn-aut-mei=耕三 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部微生物学教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=841 end-page=848 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Histological Studies on Pituitary and Adrenal Cortex in Mice with Experimental Leukemia or Mammary Cancer.

Administration of atropine does not inhibit the effect of drin compounds on blood pressure. 3. Simultaneous administration of dieldrin and adrenaline inhibits blood pressure lowering effect of dieldrin. 4. Ganglion blocking agents such as chlorpromazine and tetraethylammonium do not inhibit the effect of dieldrin on bood pressure. 5. Administration of drin compounds slows the heart rate in rabbits. 6. In rabbits given drin compounds, electrocardiograms often demonstrate depressed ST segments and low to inverted T waves. 7. In rabbits given a large amount of drin compounds, electrocardiograms may show left bundle branch block, atrial fibrillation, ventricular premature beat and multifocal idioventricular rhythm. 8.

In the case of dun compounds at a low concentration there occurs a slight decrease in the amplitude of heart beats. 2. At a high concentration, atrioventricular block and low amplitude are obserbed. Such changes are more prominent at a higher concentration, which eventually leads to diastolic cardiac arrest. 3. Premedicaticn of atropine does not reduce the suppressive action of dieldrin. 4. When atropine is given to the heart after exposure to dieldrin, an increase in the amplitude and continuance of heart beats may be seen. 5. Application of adrenaline previous to dieldrin, does not influence the decrease in the amplitude of heart beats. 6. When adrenaline is applied just prior to the cardiac arrest by dieldrin, heart beats are maintained with an increase of their amplitude. 7.

Although stellate cells of Kupffer in the liver and splenic macrophages undergo extensive proliferation during the earlier pariod of restitution after saponin poisoning, there is no evidence to indicate that these cells paticipate in the reconstruction of sinusoids in the liver and bone marrow, paticularly the latter. en-copyright= kn-copyright= en-aut-name=NakamuraTaizo en-aut-sei=Nakamura en-aut-mei=Taizo kn-aut-name=中村泰造 kn-aut-sei=中村 kn-aut-mei=泰造 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一解剖学教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=743 end-page=763 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Changes of Blood Constituents in Patients with Stomach Ulcer kn-title=胃潰瘍症の血液成分の変化に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=There have been many reports on the alterations in the blood constituents levels of patients with stomach ulcer. Some reporters stated anemia, hypoproteinemia, hypoalbuminemia, decreased serum cholinesterase activity and serum iron in the cases of stomach ulcer; but other noticed that levels of blood constituents in patient with stomach ulcer were amost within normal range. An investigation of the difference between the levels of the blood constituents of the normal and of the stomach ulcer cases was attempted. One hundred and fifty one cases of normal, 286 cases of stomach ulcer and 266 cases of stomach cancer were examined. The measured blood constitueuts were RBC, hemoglobin concentration, hematocrit, WBC and blood group. The serum constituents such as cholinesterase, alkaline phosphatase, cholesterol, glutamic pyruvic transaminase, phenol turbidity test, amylase, non-protein nitrogen, sugar, iron, copper, protein and its fractions, mucoprotein and its fractions and lipoprotein were also determined. The significant changes were statistically discussed. Decreases of RBC, hemoglobin concentration, Ht, serum cholinesterase activity, serum iron, serum albumin, A/G ratio and mucoprotein-albumin, and increases of WBC, serum GFT activity, serum amylase activity, serum NPN and globulin fraction of serum protein were noticed in the cases of stomach ulcer. It is supposed that anemia and decreased serum iron are due to the continuous bleeding from ulcer, hypoalbuminemia and decreased serum cholinesterase activity and increased GPT activity are to general deterioration by maluntrition and liver damage accompanied with stomach ulcer. Increase of serum amylase activity and serum NPN may be the sequences of pancreatic and renal involvements, the latter might be followed by the ulcer hemorrhage and dehydration. The blood constituents levels in the cases with stomach ulcer which needed the operation showed more advanced anemia and hypocholinesterasemia than in the whole ulcer cases. In the cases with large ulcer, decreased cholinesterase activity and increased NPN were prominent. The comparison of blood levels in the stomach cancer with in the stomach ulcer revealed that decreased RBC, hemoglobin concentration, serum cholinesterase activity, serum iron, gamma-globulin fraction and mucoprotein-albumin and increased alkaline phosphatase activity were significant in the group of stomach ulcer. The blood constituents levels in stomach ulcer group were situated between normal and stomach center group in regard to anemia, general deterioration and liver damage; but in the cases of large ulcer, some constituents such as serum cholinesterase, serum amylase and serum NPN were in worse condition than in the stomach cancer cases. Relationship between stomach ulcer and liver function disturbance was significantly observed in blood spectrum. Anemia, malnutrition and accompanied gastritis with stomach ulcer may induce secondary chronic liver damage, but severe liver disorder occurs rarely in the cases with stomach ulcer. en-copyright= kn-copyright= en-aut-name=SatoKimiyasu en-aut-sei=Sato en-aut-mei=Kimiyasu kn-aut-name=佐藤公康 kn-aut-sei=佐藤 kn-aut-mei=公康 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=721 end-page=742 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Changes of Blood Constituents in Patients with Gastric Polyp kn-title=胃ポリープ症の臨床検査成績についての検討（特に血液成分の変化に関して） en-subtitle= kn-subtitle= en-abstract=In order to investigate the alteration in the blood constituents levels in patients with gastric polyp and to clarify the difference between the normal, patients with gastric cancer and gastric polyp in the levels of the blood constituents, 200 cases of gastric polyp, 151 cases of normal and 266 cases of gastric cancer were examined. Examinations on blood constituents including red cell count, hemoglobin concentration, hematocrit, white cell count, cholinesterase. alkaline phosphatase, cholesterol, GPT, phenol turbidity test, amylase, NPN, sugar, iron, copper, protein and its fractions, glycoprotein and its fractions and lipoprotein were done. The results statistically discussed were as follows. 1) In white cell count, serum protein, cholesterol, phenol turbidity test, blood sugar, non protein nitrogen, copper, α-globulin fraction, β-globulin fraction, α1-glycoprotein, α2-glycoprotein, βglycoprotein and γ-glycoprotein, there were no difference between the normal and gastric polyp. 2) In the gastric polyp, decrease of red cell count. hemoglobin, hematocrit, albumin, albumin-globulin ratio, cholinesterase, serum iron, albumin fraction and Al-glycoprotein was observed. 3) In the gastric polyp, increase of globulin, GOT, GPT, alkaline phosphatase, amylase, α2-globulin fraction, γ-globulin fraction and β-lipoprotein-α-lipoprotein ratio was noticed. 4) The comparison of blood constituents levels in the stomach cancer and in the gastric polyp revealed that globulin, GPT, alkaline phosphatase and amylase in the gastric polyp were increased as much as that in the gastric cancer, and the blood constituents levels in gastric polyp were situated between those of the normal and gastric cancer in ragard to albumin, album n-globulin ratio, colinesterase, serum iron, albumin fraction, α2-globulin fraction and Al-glycoproten. It is s pposed that these changes of blood constituents in the gastric polyp are attributable to many factors, i.e. bleeding, atrophic and hyperplastic changes of the gastric mucosa with polyp and disturbance of liver and pancreas leated to that of biliary tract. It should be noticed that gastric polyp may give a marked influence to the general condition of the patients. kn-abstract= en-copyright= kn-copyright= en-aut-name=KoboriMichio en-aut-sei=Kobori en-aut-mei=Michio kn-aut-name=小堀迪夫 kn-aut-sei=小堀 kn-aut-mei=迪夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=709 end-page=720 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Effect of Anabolic Steroids on Cholesterol Metabolism Part 2.

About 100 male dogs of 10kg body weight were used at the experimental animals. The animals were divided into 3 groups: The first group was normal healthy dogs, the second was the dogs blocked the reticuloendthelial system with china ink, and the third was the dogs given carbon tetrachloride. Pyridoxal phosphate was given simultaneously to the dogs in about a half of the test animals. The results obtained were as follows; a) A reduction of serum cholesterol was observed in the healthy dogs by the administra tion of the anabolic steroido, the increased uptake of cholesterol into the liver as well as increased synthesis of trihydroxy cholanic acid and dihydroxy cholanic acid from cholesterol followed with increased excretion into bile were thought to be responsible for the reduction of serum cholesterol. b) The anabolic steroid had no hypocholesterolemic action when liver cell wasdamaged or reticulo-endothel system was blocked. c) The shift of cholesterol from blood the liver is related to liver cell and reticuloendothel system. d) Pyridoxal phosphate used with anabolic steroid resulted in no excretion of trihydroxy cholalic acid and dihydroxy oholalic acid in bile, be it seen when only the latter was administered. Pyridoxal phosphate is competitive to anabolic steroid. e) Pyridopal phosphate used with anabolic steroid had no such effect when the liver cell was damaged or reticulo-endothel system was blocked. en-copyright= kn-copyright= en-aut-name=IshiiAkemitsu en-aut-sei=Ishii en-aut-mei=Akemitsu kn-aut-name=石井明光 kn-aut-sei=石井 kn-aut-mei=明光 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=701 end-page=707 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Effect of Anabolic Steroids on Cholesterol Metabolism Part 1.

The results obtained were as follows; a) Administration of the anabolic steroids showed no significant in serum protain level, A/G ratio, the serum flocculation tests. The level of serum bilirubin was unchanged. But the Bromsulphalein retention rate and transaminase activities were increased, the serum level of cholesterol was strikingly decreased. Alkaline phosphatase was slightly decreased though it occured within normal range. b) Administration of the anabolic steroids with pyridoxal phosphate resulted in the no appreciable change in cholesterol level. The increase of transaminase activities was not observed. This phenomenon was interpreted as an conpetitive action was operating between the mechanism in which cholesterol level reduce in one side and the transaminase activities increase in the other. c) In the experiment of the dogs given H.M.D., a reduction of the serum cholesterol level was observed. The gradient was in proparation to the time after the administration. The highest level was in the partial vein, the next was in the hepatic artery, and the lowest was in the hepatic vein. From the results obtained here, is was concluded that hypocholesterolemic action occurs in the liver when the anabolic steroids were given to the patients. en-copyright= kn-copyright= en-aut-name=IshiiAkemitsu en-aut-sei=Ishii en-aut-mei=Akemitsu kn-aut-name=石井明光 kn-aut-sei=石井 kn-aut-mei=明光 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=691 end-page=700 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Antigenicity of Ehrlich Ascites Tumor Part 2, Antigenicity of Ribosomal Protein in Ehrlich Ascites Tumor kn-title=移植動物癌腫瘍抗原に関する研究 第2編 Ehrlich腹水癌腫瘍リボゾーム蛋白の抗原性について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Antigenicity of ribosomal protein in Ehrlich ascites tumor and the biochemical characters were studied.

For the identification of SDH and α-GPDH, menadione (MD) was added to the incubation medium as an intermediator. In the freshly-prepares cryostat sections of the cerebellum, the activities of LDH and SDH, as has already been reported, have been found in the granular layer (glomeruli cerebellosi), molecular layer and Purkinje cells (P-cells), but the activity of α-GPDH has hardly been detected in P-cell layer. In contrast to this findings, when the tissue block was first fixed with cold formalin solution and then frozen sections were prepared, in the course of identification of α-GPDH the formation of Nitro-BT formazans was observed in P-cells. This fact in dicates that a special precaution is required in the selection of methods and the determination of results inthe enzyme histochemistry. From this point of view, the establishment of various experimental conditions optimal for such a study have been tried with a specal reference to the problem of the fixation. The following results have been fouud with regard to the reaction in the sections fixed with formalin: 1) there is no marked difference due to the length of fixation time: 2) there is little effect due to the change in pH: 3) no specific inhibitory effect can be observed: 4) the presence of MD is prerequisite; 5) SH-group is involved; and 6) the enhancement of incorporation (adsorption; cf: substativity; Pearse) of Nitro-BT to the tissue is associated with the reaction. From these findings I have postulated that the reaction observable in the formalinfixed sections results from non-enzymic reaction in which SH-group and MD are involved, on the assumption that Nitro-BT is bound to the tissue protein. Furthevmore, the findings that P-cells do hardly exhibit the activity of α-GPDH in the non-fixed sections different from other cellular components of cerebellar tissue, as well as the fact that the non-enzymic recuction of Nitro-BT appears markedly in P-cells of the formalin-fixed specimen, seem to reflect one aspect of the cytochemical specificity of the P-cells. kn-abstract=(1) ダイコクネズミ及びヒト,ネコの小脳について,乳酸脱水素酵素(LDH),コハク酸脱水素酵素(SDH),α-グリセロ燐酸脱水素酵素(α-GPDH)活性を組織化学的に検索した. SDH,α-GPDHの検出にあたつてはintermediatorとしてmenadione (MD)を反応液に添加した. 新鮮凍結クリオスタット切片にて,LDHは顆粒層の“gloneruli cerebellosi”に相当して最も強く,分子層ではformazan顆粒はびまん性に形成されて反応は顆粒層よりやや弱くPurkinje細胞(P-細胞)は核を除いて細胞体に強度〜中等度の活性を示し,白質には活性はほとんど証明されなかつた. SDHは全体としてLDHの反応態度に似た像を示し,顆粒層に最も強く,ついでP-細胞層,分子層の順で活性が認められ,白質にはほとんど証明されなかつた. α-GPDH反応は,顆粒層,分子層においてはLDH, SDHとほぼ同じであるが,P-細胞層にはformazanの形成がほとんどなく,あたかも顆粒層と分子層の間に空隙がある様な像を示した.白質には活性はほとんど証明されなかつた,これらの所見は,これまでの報告にほぼ一致するものである. (2) 上記酵素活性の検出にあたり,新鮮凍結クリオスタット切片とともに,同一材料について組織塊をまず10%冷フォルマリンで固定した後に作製した凍結切片をあわせて使用した. SDH,α-GPDH, LDHともに反応は全般に減弱されるが,LDHの反応の減弱の度合は他の2者にくらべて少ないようであつた. ここで注目すべきことは,非固定切片のP-細胞層において,α-GPDHの活性がほとんど認められなかつたにもかかわらず固定切片のP-細胞には反応が認められ,しかもformazan形成は他の部よりもむしろ強度であつた点である.この事実は酵素組織化学における方法の選定や結果の判定にあたつては常に慎重な配慮が要求されることを示す現象であるとみなされ,この点に着目し特に固定の問題をめぐつて諸種の条件を実験的に設定してしらべた. (3) フォルマリン固定切片における反応には, i) 固定時間の長さによる著明な差異がみられない. ii) pHの変化による影響が少ない. iii) 特異的抑制剤による影響がみられない. iv) MDの存在が不可欠である. v) SH-基の関与がある. vi) Nitro-BTの組織への吸着性の増強が関連している. ということを認めた. このことからフォルマリン固定切片に見られる反応は,Nitro-BTの組織蛋白との結合性を前提とて,SH-groupとMDとが関与している非酵素的作用の結果であることを推論した. (4) 小脳組織でP-細胞が他の細胞要素と異なり,非固定切片においてα-GPDH活性をほとんど示さないこと,およびフォルマリン固定によりP-細胞に非酵素的なNitro-BT還元が著明にあらわれることは,P-細胞の細胞化学的特異性の一面を示すものであろう. en-copyright= kn-copyright= en-aut-name=TokunagaIwao en-aut-sei=Tokunaga en-aut-mei=Iwao kn-aut-name=徳永五輪雄 kn-aut-sei=徳永 kn-aut-mei=五輪雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=7-8 article-no= start-page=647 end-page=663 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Brain Metabolism on Steroid Hormones kn-title=脳におけるコルチコイド代謝 en-subtitle= kn-subtitle= en-abstract= kn-abstract=By the clinical studies on steroid hormones in endogenous mental diseases so far carried out, we have found that it is the steroids belonging to 17-KS rather than 17-OHCS which are associated with the mental excitation. In view of this, we attempted a study about the brain metabolism on testosterone which is an important precursor of 17-KS with a strong biological activity. The materials used were the brain of Donryu rats and human beings. Each of these brain tissues was homogenized in ten-fold volumes of 1/15M phosphate buffer solution. Then, taking 2ml of the brain phosphate buffer homogenate or 2ml each of 1/15M phosphate buffer suspension of the supernatant containing nuclear, mitochondrial or microsomal fraction, prepared from 1g rat brain, the incubation was conducted in the air at 37℃ for 60 minutes after adding 0.1μc [4C(14)] testosterone, 0.2 mg cold testosterone, 0.5 mg each of NAD and NADP as cofactor, and 10 mg nicotinamide. Then, metabolites were extracted, applied on the florisil column, and 2% methanol-chloroform fraction was collected and dried. For the control groups the brain tissues inactivated by heating were employed. Each of the specimens thus obtained was applied on the Silicagel-G thin layer chromatography (TLC), and metabolites were isolated and identified by the 2% NGS gas chromatography. After the TLC-autoradiography the portions that coincided with the radioactive spots was taken and each of these chromatograms was applied to the liquid scintillation counter and the percentage of the conversion of metabolites was calculated from respective radioactivity. 1) Both from the rat brain and the human brain on the TLC (chloroform-acetone-methanol, 90:7:3, developed for 15 cm) there are seen four principal spots, and designating these spots as I, II, III and IV starting from the original point of application, the spot II is testosterone, proving that 90-95% or more of testosterone added has not been metabolized. 2) The spots I and III are minor metabolites, of which I is the substance like ll-OH-Etio-cholanolone. and III is an unknown substance. The conversion rate of each is only about 0.2%, proving to be of no significant value. 3) The spot IV is a major metabolite, and on the further TLC (chloroform-acetone, 85:15, developed for 55 cm) it separated itself into two spots, each of which has been identified to be Δ(4)-androstene-3, 17-dione and dihydrotestosterone. The conversion rate of the two together is 2.46% with the rat brain and 2.29±0.73% with the human brain in average, and without addition of co factors it is decreased to 1.80% and O.5% respectively. 4) The activity of the enzymes responsible for the major metabolite formation, namely, 17β-hydroxysteroid dehydrogenase and 5α-reductase, is detectable in every fraction of the rat brain, but it is highest in the telencephalon mitochondrial and fairly high in the supernatant fraction, and the conversion rate from testosterone is about 0.5% in each case. After all, since the brain is not a metabolic organ nor a target organ, the metabolism of testosterone is extremely low, nonetheless, looking it from the aspect of its potency, we cannot rule out its significance. A further problem which we have to solve will be the role played by the hormones responsible for mental excitation, by investigating the correlation of the brain site to the metabolism of steroids including testosterone. en-copyright= kn-copyright= en-aut-name=KikuiShigeru en-aut-sei=Kikui en-aut-mei=Shigeru kn-aut-name=菊井茂 kn-aut-sei=菊井 kn-aut-mei=茂 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=7-8 article-no= start-page=721 end-page=726 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Medical Examinations on School-Children of Oki Islands kn-title=隠岐諸島小中学校学童の医学的調査について en-subtitle= kn-subtitle= en-abstract= kn-abstract=A series of medical examinations was performed on school-children of Oki Is., Shimane Pref. in April, 1967.

In eight cases of those patients electrodes were inserted stereotaxically in the Forel-H field to make some physiological study. 1. In nineteen cases (38 per cent), a complete alleviation of grand mal, in twenty-two eases (44 per cent), a moderate alleviation of grand mal were observed within postoperative three months. But there are nine cases (18 per cent) of no effect. Postoperative follow-up could reach to six moths or more in forty-two cases. In fourteen cases (33.3 per cent), marked effect, in twentyone cases, moderate, and seven cases, no effect, were observed. The operative long-term effect more or less decreases when the follow-up is extended over a longer period. 2. The side effect of this procedure was mostly transient and demonstrated light contralateral hemiparesis. In fourteen cases this was observed, but remaine in only five cases for longer period. 3. The pattern of EEG recorded from the Forel-H field was different from that of the scalp leads. The electric stimulation of the Forel-H field could not inflict on the scalp EEG. 4. EEG follow-up has been carried out in all cases but no detectable change was observed between the pre- and the post-operative EEG. en-copyright= kn-copyright= en-aut-name=HiroeToshio en-aut-sei=Hiroe en-aut-mei=Toshio kn-aut-name=広恵俊雄 kn-aut-sei=広恵 kn-aut-mei=俊雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=7-8 article-no= start-page=687 end-page=701 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Fundamental and Clinical Study of Forel-H-Tomy Part 1.

EEG recording showed localized or generalized slow wave activity immediately after the intracerebral blood injection, which continued even after two months in non-aspirated cases. Marked decrease of the slow activity was observed shortly after aspiration and EEG returned to almost normal pattern after one week.

Materials and methods of histochemical analysis were the same as the previous report. Enzyme activities in the stomach cancer cells of the patients, who showed serum hypoproteinemia, decrease of blood hemoglobin content, and increase of erthrocyte sedimentation rate, were stronger than those in the patients who had normal level of the above tests. While the relationship between enzyme activities in the stromal elements and the values of clinical tests in those groups showed the reverse tendency. No parallel relationships were observed between the alkaline phosphatase activity in cancer cells and the serum alkaline phosphatase level. Also no correlation between alkaline phosphatase activity in tumor cells and the patients liver dysfunction or liver metastasis. Leucine aminopeptidase was positive in the cancer cells of 35 per cent cases. Generally, the stomach cancers removed from anacidity or hypoacidity patients had a stronger activity of this enzyme than that of normoacidity patients. In general, enzyme activities were decreased in both of the stomach cancer cells and stromal elements obtained from the preoperatively treated with antitumor agents, such as Mitomycin C, Chromomycin A(3), and Cyclohosphamide than those from non-treated oncs. The patients who showed stronger activities in stromal elements showed distinctly a better prognosis than those weaker activities. While the patients who had stronger activities in cancer cells had worse prognosis than those weaker activities. en-copyright= kn-copyright= en-aut-name=TakeuchiKisaburo en-aut-sei=Takeuchi en-aut-mei=Kisaburo kn-aut-name=竹内鬼三郎 kn-aut-sei=竹内 kn-aut-mei=鬼三郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=7-8 article-no= start-page=637 end-page=654 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Histochemical Studies of Hydrolytic Enzymes and Dehydrogenases in the Human Gastric Cancers Part T.

Enzyme activities were compared with the histological features of stomach cancers in each patient and the grade of its advancement. Histological analysis of stomach cancer was followed by the classification established in 1962 by the Japanese Pathological Society. And the grade of advancement was judged by the criteria eatablished by the Japanese Reserch Society for Gastric Cancer. As a whole, the poorer differentiated cancer cells showed the weaker enzyme activites than the well differentiated ones. However, no correlations were observed between enzyme activities and the grade of infiltration by cancer cells. Generally enzyme activities of carcinoma simplex were weaker than those of adenocarcinom and scirrhous carcinoma showed slightlly weaker activity than carcinoma simplex. According to the classification of Borrmann, enzyme activites of infiltrative types were weaker than those in localized types. Lactic dehydrogenase showed the strongest staining intensity in all of the enzymes. The activity was observed in hydrolytic enzymes of carcinoma cells in the following desending order: beta-glucuronidase, beta-esterase, acid phosphatase, leucine aminopeptidase and alkaline phosphatase, while in that of stromal elements : beta-glucuronidase, acid phospbaase, beta-esterase, alkaline phosphatase and leucine aminopeptidase. The activity of dehydrogenases of carcinoma cells was in the following desending order: lactic, malic, glucose-6-phoshate, isocitric, succinic, alpha-glycerophosphate, glutamic and beta-hydroxybutyric dehydrogenase, and in that of stromal elements : lactic, malic, succinic, alpha-glycerophosphate which was similar to glutamic, beta-hydroxybutyric similar to glucose-6-phosphate and isocitric dehydrogenase. There was a tendency that the cancer tissues obtained from the patients of more advanced stage showed the stronger activity of enzymes than that of early stage ones. en-copyright= kn-copyright= en-aut-name=TakeuchiKisaburo en-aut-sei=Takeuchi en-aut-mei=Kisaburo kn-aut-name=竹内鬼三郎 kn-aut-sei=竹内 kn-aut-mei=鬼三郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=7-8 article-no= start-page=619 end-page=635 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Diencephalo-Pituitary Adrenocortical Functions and Role of Frontal Lobe to These Systems in Mental Diseases kn-title=精神病者の間脳・下垂体・副腎皮質系機能及び前頭葉関与に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=As a link in the series of studies on the functions of the diencephalo-pituituitary adrenocortical system in endogenous psychosis, an investigation was carried out on 26 cases of schizophrenia who received the standard bilateral lobotomy, for the purpose to find out how the frontal lobe affects to the endocrine functions and autnomic nervous systems. For this purpose ACTH (25 units) was administered intramuscularly to 17 cases of them, and the m echolyltest was conducted with the other 9 cases, measuring the lelvels of corticoids in serum and urine of both groups. For the controls, ACTH was administered to 9 cases of schizophrenia who did not receive lobotomy. The results of the study may briefly be summarized as follows. 1) In the control group after ACTH adiministration the serum 17-OHCS showed a tendency of a decrease in the cortical reserve capacity, and in the lobotomized group there could be seen an abnormal reaction to ACTH in addition to a decrease in the cortical reserve capacity. 2) Total blood cholesterol after the ACTH stimulation decreased temporarily, showing similar changes up to 30 minutes in both groups, but in the lobotomized group an increase in cholesterol could be observed thereafter, revealing a contrasting phenomenon to the decreasing tendency of the serum 17-OHCS. 3) The blood potassium decreased transiently 10 minutes after the ACTH administration in both groups and such changes were unstable in the control group while the blood potassium in the lobotomized group increased steadily. As for the fluctuations of urine potassium its excretion was decreased transiently after the ACTH administration in both groups, which later rebounded, and this recovery tendency was more marked in the lobotomized group. 4) 17-KS excreted in urine on ACTH stimulation increased accompanying a marked increase in the amount of urine in the case of lobotomized group. 5) The results of the mecholyl test revealed that even the lobotomized patients respond to mecholyl, but there can be observed a decline and delay in the reactivity. 6) Observations on the fluctuations of serum 17-OHCS, urine 17-OHCS and 17-KS conducted simultaneouly with the mecholyl test revealed a declinining tendency in serum free 17-OHCS while total 17-OHCS in urine to be rather increased in the lobotomized group. The quantity of 17-KS excreted in urine decreased at first and then increased, and such a tendency did not parallel with the change in the total 17-OHCS excreted in urine. In the patients showing identically the same pathological conditions there could be recognized no distinct correlation between the type of response to mecholyl and the corticoid picture. 7) While we can recognize a certain correlation between defect symptoms of the frontal lobe and the endocrine functions, when we investigate individual caes, we find complex features in the endocrine function and autonomic nervous system according to the constitution before the lobotomy and the postoperative pathological picture. Namely, in those patients in a quiet mentbal state, though they are not completely cured, both functions maintain the balance in the state of lowered tension. On the other hand, in those who show a premonition of unrest and excitation, both functions have become unstable. Moreover, those who may have hallucination and delusion and are in the state of chronic defect, so long as there occurs no excitation, they show the levels of function close to the normal. 8) Summarizing these findings, it may be said that there is a decreasing tendency of the response to the ACTH stimulation in the functions of the diencephalo-pituitary-adrenocortical system of chronic shizophrenic group, and distribution of the estimated values is larger than that of normal persons, and this tendency is still more pronounced in the lobotomized group. Furthermore, the dissection of the frontal lobe brings about a defective equilibrium in the reaction mechanism of regulating center in endocrine system, but once placed under a strong stimulus, this balance is broken and there occurs a marked disruption in the endocrine rhythm. en-copyright= kn-copyright= en-aut-name=IzumiyaKazunori en-aut-sei=Izumiya en-aut-mei=Kazunori kn-aut-name=出宮一徳 kn-aut-sei=出宮 kn-aut-mei=一徳 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=7-8 article-no= start-page=589 end-page=597 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Electron Microscopic Study of Japanese Encephalitis VirusPart T.

At various intervals following infection, the cells were fixed in buffered 1% osminum tetroxide-solution, embedded in methacrylates and cut on a Leitz ultramicrotome. After the sections were stained in saturated uranyl acetate solution, they were observed in the Hitachi type HUll electron microscope. It is suggested that the JE virus particle is hexogonal in shape and approximately 40 mu in the longest diameter, it is composed of an outer membrane 20 A° thick viroplasm 30 A° thick, and an electron dense nucleoid 25 mu in diameter. en-copyright= kn-copyright= en-aut-name=MogurumaMasahito en-aut-sei=Moguruma en-aut-mei=Masahito kn-aut-name=六車昌士 kn-aut-sei=六車 kn-aut-mei=昌士 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=7-8 article-no= start-page=585 end-page=588 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Steroid Metabolism in Walker Carcinoma Bearing Rat Part U.

Results obtained were as follows. 1. Mg had a most preventive effect on the reduction of WBC due to MMC, following by SM, CO and SV. 2. On the fluctuation of RBC, SM, Mg, OA and CO showed better results. 3. No agents tested were effective on the prevention of reduction in platelets. 4. No unwilling decrease in tumor-effects were noted in these agents. 5. Survival time was markedly extended in case of using SM. Summarizing the results obtained above, streptomycin was a most useful agent for the prevention of side-effects of Mitomycin-C. Under the fundamental investigation, streptomycin was clinically used in case of giving Mitomycin-C, and the side-effects were remarkably reduced as seen in the experiment. Further studies would have to be continued on the other anticancer agents. en-copyright= kn-copyright= en-aut-name=MurataMasahiko en-aut-sei=Murata en-aut-mei=Masahiko kn-aut-name=村田雅彦 kn-aut-sei=村田 kn-aut-mei=雅彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科教室 END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=7-8 article-no= start-page=361 end-page=372 dt-received= dt-revised= dt-accepted= dt-pub-year=1970 dt-pub=19700831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on acid base balance of the cerebrospinal fluid under acute intracranial hypertension kn-title=急性頭蓋内圧亢進時の髄液酸塩基平衡に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The author devised on pparatus for continuous monitoring of acid base balance of CSF without any CSF exposure to the atomosphere. The apparatus is an extracorporeal "ventriculo-cisternal circulation system" which is consisted of pressure pump, glass capillary electrode, Clark PO(2) eleotrode and Severinghaus Pco(2) electrode, all-lined up on a stainless steal conduit betweeen lateral ventricle and cisterna magna. In the experimental cases of 5 dogs, the ventriculo-cisternal circulation system was used for monitoring acid base balanec of the CSF under acute intracranial hypertension produced by extradural balloon inflation. The blood Pco(2) was constantly watched during experiment to be kept in the normal range by means of a respirator. Pco(2) in the CSF began to increase in early stage above the pressure of CSF of 300 mmH(2)O and incseased more and more in parallel with raised pressure. HCO(3)- in the CSF was decreased when acute and more severe intracranial hypertension was maintained for hours. Hypercapnic acidosis and metabolic acidosis occured in the CSF specifically when the intracranial pressure was raised acutely. Clinically, acid base balance of the CSF was studied on acute intracranial hypertension of three patients who suffered from brain tumor. Intracranial pressure was monitored continuously by pressure gauge transducer connected to the ventricular drainage. In this clinical research, CSF, arterial blood and jugular blood were sampled for measurement. Pco(2) in the CSF was increased when the intracranial pressure was elevated above 500mmH(2)O and metabolic acidosis was added when the pressure was more elevated continued. That is to say, CSF became acidosis as same as experimental results. On the contrary, arterial blood became respiratory alkalosis when the intracranial pressure was elevated to 500-1000mmH(2)O. This phenomenon suggest that increse of hydrogenic ions induced by intracranial hypertension stimulates respiratory center. Hypercapnic acidosis and metabolic acidosis occur specifically in the CSF independently from the change in the blood when the intracranial pressure rises. Namely, the acid base balance of the CSF can not evaluated from that of the blood. The author adovocates this state is hidden acidosis. en-copyright= kn-copyright= en-aut-name=DoiAkihiro en-aut-sei=Doi en-aut-mei=Akihiro kn-aut-name=土井章弘 kn-aut-sei=土井 kn-aut-mei=章弘 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=7-8 article-no= start-page=355 end-page=360 dt-received= dt-revised= dt-accepted= dt-pub-year=1970 dt-pub=19700831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=TWO CASES OF PRIMITIVE TRIGEMINAL ARTERY Two cases of persistent carotid basilar anastomosis are reported kn-title=case report Persistent Primitive Trigeminal Arteryの2症例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The first case is 28 years old femal who admitted with porphyrin-uria and left sided visual disturbance which was occured suddenly with vomitting.

The results obtained were as follows. 1. The high concentrations of sulfur dioxide measured practically at Fukuda-cho station could be logically explained by the diffusion called C-stability following Pasquill, and those at Amagi station could be also explained by the diffusion called D-stability. 2. Under the condition of each of A and B stabilities following Pasquill, sulfur dioxide diffused itself significantly on C-stability in Pasquill's chart, and in the case of each B and C stabilities, it diffused itself on D-stability in Pasquill's chart. en-copyright= kn-copyright= en-aut-name=InoueKentaro en-aut-sei=Inoue en-aut-mei=Kentaro kn-aut-name=井上堅太郎 kn-aut-sei=井上 kn-aut-mei=堅太郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=7-8 article-no= start-page=189 end-page=200 dt-received= dt-revised= dt-accepted= dt-pub-year=1972 dt-pub=19720830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on the Mechanism of phagocytosis: Effect of Ionic strength on Adhesion of Fixed Red Blood Cells to Monocytes kn-title=細胞の貪食作用に関する研究―単球の固定赤血球付着に及ぼすイオン強度の影響― en-subtitle= kn-subtitle= en-abstract= kn-abstract=For the purpose to clarify whether electrostatic contributes to the adhesion of red blood cell to monocyte, first phase of phagocytosis, was studied in vitro in ion deficient environments comparing with that in ionic environments. The experiments were carried out by using mouse ascites macrophage and the fresh and fixed red blood cells of mouse and chicken. Observations revealed that in Hanks' solution, the fixed red blood cells adhered to the monocyte, while fresh red blood cells of both species did not. In isotonic sugar aqueous solutions, however, the fixed red blood cells did not adhere to the monocyte. The test in the varied ionic concentration proved that number percent of monocytes adhering the fixed red blood cells to the total monocytes reduced in proportion to logaritsm of the decrease in ionic strength of the media. Concentration of Ca(++) and Mg(++) and pH of the media gave actually no effect on the red blood cell adhesion to the monocyte. The red blood cells fixed and conditioned with methylation treatment adhered to the monocytes even in ion free sucrose solution, but those conditioned with desamination treatment did not. From these results it is concluded that the ionic strength in the media is a decidive factor for the fixed red blood cell adhesion to the macrophage. Discussion was made on the mechanism of the adhesion from the view point of lyopobic and lyopilic colloid mechanism. en-copyright= kn-copyright= en-aut-name=ShimizuYoriko en-aut-sei=Shimizu en-aut-mei=Yoriko kn-aut-name=清水頼子 kn-aut-sei=清水 kn-aut-mei=頼子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一病理学教室 END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=7-8 article-no= start-page=177 end-page=188 dt-received= dt-revised= dt-accepted= dt-pub-year=1972 dt-pub=19720830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Structure of Blood Vessels in Malignant Tumors kn-title=悪性腫瘍の血管構造に関する研究 第3編 腫瘍ならびに肺の血管に及ぼすBleomycinの影響について en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the purpose of elucidating the role of the stroma for the growth of tumors, the vascular structures in the parenchymal stroma and the surroundings of animal tumors were studied. In the first chapter, the vascular structures of Bashford tumors and Ehrlich subcutaneous tumors were examined employing the India ink method. The Blood vessels of tumors are derived from their surrounding host connective tissue. The structure of blood vessels of every tumor has features of its own. Further, it was observed that metastatic tumors in the lungs of Ehrlich ascites carcinoma and Brown-Pearce tumors had an individuality in their vascular structures. In the second chapter, the vascular structures of Ehrlich subcutaneous tumors and first generation transplants of C(3)H spontaneous mammary cancers were observed employing ultrasoft X-ray, and the relationship between the blood vessels and the stromaltissue of these tumors was investigated using several special staining methods. Characteristic features were also observed on the vascularization and the stromal tissues of Ehrlich subcutaneous tumors treated with chondroitin sulphate. In the third chapter, the influences of administration of Bleomycin on C(3)H spontaneous mammary cancers were abserved with respect to the vascular struture and stromal tissue. It was found that small tumor vessels were narrowed, obstructed and destroyed by administration of this drug. Further, it was observed that the vasculature and stromal tissue of lungs of mice and humans administered with this agent were likewise damaged, and that prednisolone and chloroquine considerably inhibited these pulmonary damages caused by this drug. en-copyright= kn-copyright= en-aut-name=NishishitaAkira en-aut-sei=Nishishita en-aut-mei=Akira kn-aut-name=西下明 kn-aut-sei=西下 kn-aut-mei=明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=7-8 article-no= start-page=167 end-page=176 dt-received= dt-revised= dt-accepted= dt-pub-year=1972 dt-pub=19720830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=悪性腫痕の血管構造に関する研究 第2編 血管構築と癌の間質について en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=西下明 kn-aut-sei=西下 kn-aut-mei=明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=7-8 article-no= start-page=157 end-page=166 dt-received= dt-revised= dt-accepted= dt-pub-year=1972 dt-pub=19720830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=悪性腫瘍の血管構造に関する研究 第1編 動物癌の血管構築について en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=西下明 kn-aut-sei=西下 kn-aut-mei=明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=7-8 article-no= start-page=143 end-page=155 dt-received= dt-revised= dt-accepted= dt-pub-year=1972 dt-pub=19720830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The antimitotic effect of cornin extracted from dog intestine kn-title=イヌの小腸から抽出したコルニン分画の細胞分裂抑制作用に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The antimitotic effect of cornin extracted from dog intestine, are summarized as follows. 1. Canine intestine cornin (CIC) inhibit the proliferation of HeLa cell in tissue culture. It's antimitotic effect, however, increases depend on the cornin dose per cell. 2. CIC is stable substance. Antimitotic effect of CIC does not decrease after stocking in desiccater over 3 years, and also 2 days preincubation in 37℃. DTT treated CIC show no differences with untreated CIC in growing HeLa cell. 3. Both dialysable and nondialysable fractions show antimitotic effect to HeLa cell. And nondialysable fraction is more effective. 4. Ultrafiltration is done by Diafilter membrane. The most effective fraction of molecular weight is over than 55,000. The next is molecular weight 20,000~55,000, the third is molecular weight below 10,000. The component molecular weight 10,000~20,000 is slightly effective. 5. The antimitotic effect of molecular weight over than 55,000 fraction decreases by 2 days treatment in 0.025% trypsin at 37℃. 6. CIC is separated in 3 fractions by Sephadex G200 column. The most effective fraction is FV. It suggests that the antimitotic action of CIC is more effective in relatively small molecular weight of molecular weight over than 55,000 fraction. en-copyright= kn-copyright= en-aut-name=MakiyamaMasao en-aut-sei=Makiyama en-aut-mei=Masao kn-aut-name=牧山政雄 kn-aut-sei=牧山 kn-aut-mei=政雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一生理学教室 END start-ver=1.4 cd-journal=joma no-vol=81 cd-vols= no-issue=7-8 article-no= start-page=495 end-page=504 dt-received= dt-revised= dt-accepted= dt-pub-year=1969 dt-pub=19690830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estimation of Urinary 17-KS Fractions by Thin Layer Chromatography kn-title=TLCを用いた尿中17-KSの10分画測定値並びに分画比に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The subjects study were consisted of 20 nomal healthy males, two groups of 20 women each with normal menstrual cycle, one group of proliferative phase and the other of secretory phase, 10 castrated women, 11 climacteric women and 11 of various diseases. With 24-hours urine collected carefully from these subjects, 10 fractions of 17-KS were measured. For the estimation of fractions, 2-step hydrolysis of β-glucuronidase hydrolysis and solvolysis was conducted first, then ether extraction, rinsed with water, washed again with alkali, dehydrated, dried and fixed, the separation of C(10) fractions was done by Florisil column chromatography with the methanol-chloroform system, and 10 fractions of 17-KS were finally isolated by TLC using 55 cm glass plate. For colorimetry alcoholic Zimmemann's technic was conducted and each 17-KS fraction of the 24-hour urine was estimated. By these procedures, the following results were obtained. 1) After TLC of the purified extracts prepared by the two step hydrolysis, the percentage of β-glucuronidase hydrolysate and solvolysis hydrolysate was determined. As a result, it was found that urinary 17-KS contains 67% of β-glucuronidase hydrolysate and 33% solvolysis hydrolysate. Of the fractions, W, Y, [ and \ fractions in β-glucuronidase hydrolysate were over two-fold those in solvolysis hydrolysate. 2) By measuring 10 fractions of 17-KS in 24-hour urine from normal females at proliferative phase, secretory phase and from normal male, values and their ratios were established, The ratios of 10 fractions showed no appreciable difference due the sex gland but the values of U, V, W, X and Y fractions of normal males were more than twice those of normal females. These 11-deoxy-17-KS said to compose the so-called sex gland system show distinct sex differences. Namely, in sum total normal males showed the values 1.9 times of those of normal females. However, these could be seen no significant differences in these values between the women of proliferative phase and those of secretory phase. 3) In the comparative study of the effects of sex gland and adrenals on urinary 17-KS and on the fraction ratio in the groups of castrated women and climacteric women on one hand, and nomal women and men on the other, W, X and Y fractions of the 11-deoxy-17-KS groups seem to be derived from the sex glands. Especially, androsterone in normal men is six times that of castrated women, and that of normal women is 3-fold that of castrated women. On the other hand, the excretin of the 11-oxy-17-KS group is not much affected by castration, but as the fraction ratio is increased, this 11-oxy-17-KS group seems to be derived from adrenals. Opinions are divided in that these are many who contend (9)10)11)) that the values of urinary 17-KS are not affected by oophorectomy, and some (12)) claim that these can be observed no decrease in the 11-deoxy-17-KS. However, these differences in the opinions seem to be due to the methods of messurements and the development of those. By the author's own results, the values of 11-deoxy-17-KS are decreased by castration while 11-oxy-17-KS values are somewhat increased. The sum total value of the fractions in the castrated women has been found to be 87% that of normal women at proliferative phase. 4) In the fractionratios between castrated women and climacteric women V, W and X fractions show higher values in the latter group but Y fraction said to belong to the sex gland system is found to show higher values in castrated women. This seems to be due to the formation etiocholanolone by passing the pathway of THS→11-deoxy-cortol. 5) A new finding that cannot be overlooked and the like of which is not seen in the available literature is the fact average value of androstanedione excreted into urine is 840 μg in normal women, 1190 μg in nomal men, 900 μg in castrated women and 470 μg in climacteric women. 6) Some discussion was made simultaneously about estimated values of urinary 17-KS fractions in several diseases with abnomality in the sex gland and adrenals, though the cases studied were only a few in number. en-copyright= kn-copyright= en-aut-name=SuzukiShiro en-aut-sei=Suzuki en-aut-mei=Shiro kn-aut-name=鈴木四郎 kn-aut-sei=鈴木 kn-aut-mei=四郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部産婦人科教室 END start-ver=1.4 cd-journal=joma no-vol=81 cd-vols= no-issue=7-8 article-no= start-page=487 end-page=494 dt-received= dt-revised= dt-accepted= dt-pub-year=1969 dt-pub=19690830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cytological Studies on Human Pleural Effusion by Tissue Culture Part 2.

As a result it has been demonstrated that by 5 days after Ehrlich cancer transplantation antitumor activity can be detected in any of lymphatic tissues, while by about 8-10 days there appears a strong antitumor activity first in the regional axillary lymph-nodes cells and lymphoid cells of spleen, but at this stage such an antitumor activity cannot yet be seen in the distant mesenterial lymph-node cells. After lapse of 15, 20 and 22 days a strong antitumor activity appears in the distant mesenterial lymph-node cells, which becomes stronger with lapes of time. On the other hand, in the spleen the antitumor activity weakens and disappears with lapse of 15, 20, and 22 days. In the case of axillary lymph nodes by 15th day there can still be observed a strong antitumor activity, which grows gradually weaker by 20th and 22nd days. The fact that, when left standing without any treatment, concomitant immunity in the cancer-bearing mouse destined to die of tumor death appears first in regional lymph nodes, which is gradually strengthened, and such a concomitant immunity appears later in distant lymph nodes, indicates that the concomitant immunity differs according to different sites of the body. en-copyright= kn-copyright= en-aut-name=TomoyasuSatoshi en-aut-sei=Tomoyasu en-aut-mei=Satoshi kn-aut-name=友保敏 kn-aut-sei=友保 kn-aut-mei=敏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科教室 END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=7-8 article-no= start-page=403 end-page=408 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cultivation of Human Lymphoblastoid Cells in Diffusion Chambers Implanted in the Abdominal Cavity of MiceU.

The majority of cells before intraperitoneal implantation were lymphoblasts with approximately 16% mature lymphocytes. However, after 3 weeks of in vivo cultivation in diffusion chambers, macrophage-like cells began to increase and occupied 80-90% of cells after 4 and 5 weeks. These macrophage-like cells, when tested for phagocytic activity after 4 weeks, exhibited bacterial phagocytosis. Labeling studies with (3)H-thymidine indicated that active DNA synthesis continued for up to 2 weeks of in vivo diffusion chamber cultivation, during which mitotic figures were also observed morphologically. Further, it was attempted to recultivate in vitro cells that were taken out of diffusion chambers after 2, 3, and 4 weeks of in vivo implantation. These 3 separate attempts led to the development of lymphoblastoid cells that were morphologically and cytogenetically similar to those prior to diffusion chamber implantation. From these findings, it is suggested that human lymphoid cells undergo morphologic alteration to macrophages under certain circumstances. en-copyright= kn-copyright= en-aut-name=YoshimotoShuko en-aut-sei=Yoshimoto en-aut-mei=Shuko kn-aut-name=吉本修子 kn-aut-sei=吉本 kn-aut-mei=修子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科 END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=7-8 article-no= start-page=385 end-page=392 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Fatty Acids Metabolism of Goldthioglucose Obese Mice U.

In this report, the incorporation of (14)C from (U)-(14)C-palmitic acid, 1-(14)C-linoleic acid and 1-(14)C-γlinolenic acid into individual fatty acids and major lipid classes of liver was determined in vivo. Results were as follows. 1) No significant differences between GTG and control mice were found in the incorporation of (14)C into saponifiable fraction of lipids (total fatty acids) from (14)C-palmitic acid, (14)C-linoleic acid and (14)C-γ-linolenic acid. 2) In the percentage distribution of (14)C in malor lipid classes in both groups of mice, it was found that (14)C come from (14)C-palmitic acid was incorporated mainly into triglyceride, (14)C from (14)C-linoleic acid into triglyceride and phospholipids, and (14)C from (14)C-γ-linolenic acid. mainly into phospholipids. A few differences between. GTG and control mice were found in the percentage distribution of (14)C from (14)C-palmltic acid, (14)C-linoleic acid and (14)C-γ-linolenic acid in triglyceride and phospholipids. 3) In regard to the study on the incorporation of (14)C into individual fatty acids of saponifiable fraction of lipids, the percentage of (14)C recovered in palmitic acid from (14)C-palmitic acid more increased and that in stearic acid more decreased in GTG mice than in control mice. When (14)C-linoleic acid was used as precursor the percentage of (14)C recovered in linoleic acid was 55-62% and that in arachidonic acid was about 12% of 14C in total fatty acids, in both groups of mice. However, the percentage distribution of (14)C in γ-linolenic acid from (14)C-γ-linolenic acid was 10% and that in arachidonic acid was 46-58% , in both groups of mice. The rate of conversion from γ-linolenic acid to arachidonic acid more increased in GTG mice than control mice. 4) In regard to the esterification of individual fatty acids into major lipid classes, it was found in both groups of mice that linoleic acid was more esterified into tryglyceride than into phospholipids, and arachidonic acid was esterified mainly into phospholipids. From these results, metabolism of palmitic acid and essential fatty acids in GTG mice is characterized by increased palmitic acid pool and increased ratio of the conversion from γ-linolenic acid to arachidonic acid. en-copyright= kn-copyright= en-aut-name=FujiiYasuhisa en-aut-sei=Fujii en-aut-mei=Yasuhisa kn-aut-name=藤井靖久 kn-aut-sei=藤井 kn-aut-mei=靖久 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科学教室 END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=7-8 article-no= start-page=369 end-page=383 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Fatty Acids Metabolism of Goldthioglucose Obese Mice T.

A considerable number of papers have been published on lipid metabolism of liver and adipose tissue in these obese animal. However, little is known about individual fatty acids synthesis in GTG mice. In this report, the author disclosed the individual fatty acids synthesis of liver and adipose tissue in GTG mice. Observations were performed both in vitro and in vivo, with analysis of the incorporation and distribution of 1-(14)C-acetate in individual fatty acids of major lipid classes Results were as follows. Experiment on liver; 1) Liver of GTG mice incorporated significantly more 1-(14)C-acetate in saponifiable fraction of lipids (=total fatty acids) than liver of control mice did. 2) In regard to the study on the distribution of 1-(14)C-acetate in individual fatty acids separated by gaschromatography, the percentage of radioactivity recovered in oleic acid significantly increased in GTG mice. On the other hand, the percentage of radioactivity in fatty acids with retention time corresponding to arachidic acid or longer relatively decreased. 3) After four hours' incubation of liver with 1-(14)C-acetate in vitro, the percentage distribution of radioactivity recovered in triglyceride significantly increased in GTG mice comparedd with control mice. In vivo, the percentage distribution of radioactivity increased in liver triglyceride with time from one hour to four hours after administration of 1-(14)C-acetate in GTG mice. 4) It is conspicuous that the amount of radioactivity recovered in oleic acid of GTG mice was always significantly higher than in that of control mice, on analysis of (14)C distribution in individual fatty acids esterified into triglyceride, both in vitro and in vivo. The percentage distribution of (14)C in oleic acid of triglyceride in GTG mice was increasing with time up to four hours in vivo, too. 5) In individual fatty acids esterified into phospholipids, the percentage of (14)C found in oleic acid of GTG mice was also higher than in that of control mice. 6) In vitro, fasted animals incorporated less (14)C into total fatty acids than fed animals in both GTG and control mice and significant decrease was observed in the percentage of (14)C in myristic acid and palmitic acid. Experiment on adipose tissue; There was a highly significant increase in the incorporation of (14)C into total fatty acids in the tissue of GTG mice compared with control mice. However, no significant differences were found in the percentage distribution of (14)C in major lipid classes nor in individual fatty acids of saponifiable fraction of lipids between both groups of mice. From these results, the author advocates a possibility that obesity of these animals is due to the increased synthesis of fatty acids and increaed accumulation of triglyceride esterified with oleic acid. en-copyright= kn-copyright= en-aut-name=FujiiYasuhisa en-aut-sei=Fujii en-aut-mei=Yasuhisa kn-aut-name=藤井靖久 kn-aut-sei=藤井 kn-aut-mei=靖久 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科学教室 END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=7-8 article-no= start-page=309 end-page=331 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Psychosomatic Studies on Colonic Dysfunction: Interrelationship between Diarrhea and/or Constipation with Sociopsychological Factors particularly observed in Adolescents kn-title=便通異常に関する心身医学的研究―思春期にみられる下痢・便秘症状と社会心理的因子との関連性― en-subtitle= kn-subtitle= en-abstract= kn-abstract=A psychosomatic study was conducted with grade school and high school students to examine the occurrence of diarrhea and constipation in relation to their perception of illness. In order to find out in greater detail the nature of diarrhea and constipation and the awareness of illness in adolescents, a further psychosomatic study was conducted by questionnaires, psychological tests, interviews and somatic examinations. A follow up study was conducted two and a half years later. The main results were as follows. 1. The incidence of diarrhea and constipation increased significantly in so-called adolescence over the period from junior high school to senior high school. Boys had more diarrhea while girls more constipation. 2. Those who had only one bowel movement a day were found in 61 to 72% of the male population, while in only 50 to 69% of the female population. In regard to the type of stool, as many as 11 to 21% of boys and 11 to 24% of girls reported that they usually had soft, hard or sheepdung stools. As they were mostly healthy students, these findings suggest that the awareness of illness is an important factor in diagnosing irritable colon syndrome. 3. Significant interrelationship was proven to exist between the occurrence of diarrhea and/or constipation and sociopsychological factors such as anxiety, emotional unstability and social maladaptation. 4. Significant interrelationship was proven to exist between the awareness of illness and sociopsychological factors. 5. Almost 2/3 of the students who have diarrhea and/or constipation with the awareness of illness developed their first symptoms during the period of preparing for enter to the upper schools and/or for adjusting to the new school surroundings. Among their precipitating factors anxiety and tension in connection with school examinations were mentioned by 2/3 of the students. 6. About 2/3 of both diarrhea and constipation types showed a lymphoid hyperplasia in the part of terminal ileum by the X-ray examination. In the lactose tolerance test (50g), more than 80% of both types showed less than 20mg/dl of the maximum rise of blood sugar. However, there was no significant difference between these two types. 7. The. significant interrelationship between the occurrence of diarrhea and/or constipation and sociopsychological factors was supported by the follow up study which was carried out two and a half years later. en-copyright= kn-copyright= en-aut-name=NakanoShigeyuki en-aut-sei=Nakano en-aut-mei=Shigeyuki kn-aut-name=中野重行 kn-aut-sei=中野 kn-aut-mei=重行 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳代謝研究施設病態生化学部門 END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=7-8 article-no= start-page=299 end-page=307 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=CONTRIBUTION OF CELL SURFACE TO SALT TOLERANCE OF STAPHYLOCOCCUS AUREUS -STUDIES BY FREEZE-ETCHING METHOD- kn-title=黄色ブドウ球菌の耐塩機構における細菌表層の役割 特にフリーズ・エッチング法による形態学的検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The role of cell surface in a haloresistant mechanism of S. aureus was analyzed by free-ze-etching method. Our comparative studies were carried out on S. aureus cultivated in 0.5% NaCl containing medium (Normal-Staph) and in 10% NaCl containing medium (10% -Staph), as they were or were treated with L-11 enzyme (cell wall lytic enzyme obtained from Flabobacterium sp.). 1. As shown in photographs of non-treated and enzyme-treated cells, both the cell size and cell wall thickness of 10% -Staph increased to about 1.5 times Normal-Staph. 2. When Normal-Staph was exposed to L-11 enzyme, there occurred a gradual decrease in the OD. In the case of 10% -Staph, the OD showed a down-slope with a shoulder which rose in OD once at about 10 minutes after incubation. 3. The surface pattern of plasma membrane of Normal-Staph appeared to be made up of closely arranged spherical subunits. But in the case of 10% -Staph, the spherical subunits were indistinct and appeared to be sparsely located. en-copyright= kn-copyright= en-aut-name=TomochikaKen-ichi en-aut-sei=Tomochika en-aut-mei=Ken-ichi kn-aut-name=友近健一 kn-aut-sei=友近 kn-aut-mei=健一 aut-affil-num=1 ORCID= en-aut-name=SasaiKatsuko en-aut-sei=Sasai en-aut-mei=Katsuko kn-aut-name=篠井加津子 kn-aut-sei=篠井 kn-aut-mei=加津子 aut-affil-num=2 ORCID= en-aut-name=KanemasaYasuhiro en-aut-sei=Kanemasa en-aut-mei=Yasuhiro kn-aut-name=金政泰弘 kn-aut-sei=金政 kn-aut-mei=泰弘 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部微生物学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部微生物学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部微生物学教室 END start-ver=1.4 cd-journal=joma no-vol=86 cd-vols= no-issue=7-8 article-no= start-page=293 end-page=298 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Three Early Gastric Cancers of Superficial Depressive Type on the Greater Curvature kn-title=胃大弯側陥凹性早期癌の3症例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=With advance in the double irridigoradiographic technique the detection of early gastric cancer has markedly increased.

Forty-five point seven percent of the farmers had some complaints after spraying the agent, which included fatigue, headache, nausea, anorexia, diarrhea, insomnia or abdominal pain. 2. Blood pictures of the farmers after spraying the agent indicated slight decrease or no change or hemoglobin and erythrocytes with the tendency of a higher color index than normal, and leukocytosis with neutrophilia. These blood changes, however, returned to normal in 6 months after the use of the agent. 3. Increased urinary urobilinogen and glycosuria were present in some cases, but none showed proteinuria. 4. Liver function tests revealed an increased icterus index and positive CCLF in some cases, but no abnormalities were found in TTT, ZTT, transaminases. There appeared to be no clinically appreciable liver disease. 5. ECG showed slight bradycardia and elongated P-Q intervals within normal ranges but no arrhythmia. No heart disease was clinically manifested in any cases. en-copyright= kn-copyright= en-aut-name=HashidaKunio en-aut-sei=Hashida en-aut-mei=Kunio kn-aut-name=橋田邦夫 kn-aut-sei=橋田 kn-aut-mei=邦夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科 END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue=7-8 article-no= start-page=273 end-page=293 dt-received= dt-revised= dt-accepted= dt-pub-year=1971 dt-pub=19710830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Agricultural Organofluoride Poisoning Part T Experimental and clinical studies on organofluoride poisoning with emphasis on treatment kn-title=有機フッ素剤中毒に関する研究 第1編 有機フッ素剤中毒の治療を主とした実験的ならびに臨床的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Treatment experiments and blood sugar determinations were carried out on organofluoride-intoxicated animals and the results were as follows. 1. FAM (monofluoroacetamide)-intoxicated rats were treated with various acetyl radical transferring compounds of which acetamide was found to be most effective and resulted in 100% recovery of the animals treated. Treatment with ethanol monoacetin, and glucose led to the prolongation of survival times of the intoxicated rats. Some increases of the survival times and anticonvulsive effects were obtained also by the use of phenobarbital and procainamide. 2. Administration of acetamide and procainamide to FAM-intoxicated rabbits resulted in approximately twice as longer survival times as those of the controls. 3. FAM administered rats showed a general tendency to low blood sugar levels, and the more the dosage of FAM was given, the greater the degree of hypoglycemia was observed. The maximum decrease was noted in the midst of or before and after convulsions of the administered rats. Methylparathion and Endrin administered rats, on the contrary, indicated increased levels of blood sugars. These observations suggest that determination of blood sugar levels can be a clue to differentiating organofluoride-intoxication from organic phosphate and chloride (especially Endrin)-intoxications which occur frequently in Japan. And this point may contribute to the understanding of the etiology of organofluoride-intoxication. 4. A close relationship between unconsciousness and a decrease in blood sugar levels was obtained in a MNFA (N-methyl-N-(1-naphthyl) monofluoroacetate)-intoxicated human case. Administration of large doses of glucose was found to be very effective for the recovery of unconsciousness. en-copyright= kn-copyright= en-aut-name=HashidaKunio en-aut-sei=Hashida en-aut-mei=Kunio kn-aut-name=橋田邦夫 kn-aut-sei=橋田 kn-aut-mei=邦夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科 END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue=7-8 article-no= start-page=267 end-page=271 dt-received= dt-revised= dt-accepted= dt-pub-year=1971 dt-pub=19710830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=In vitro transformation of mouse embryo cells by SV 40 DNA kn-title=SV40DNAによるマウス胎児培養細胞の試験管内発癌について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The oncogenicity of SV 40 DNA was examined in mouse embryo cell cultures in vitro.

We tentatively classified the Ec-cells into two types; Ec-T-cell and Ec-U-cell. The specific granules in the Ec-T-cells are polymorphous and contain a dense core enclosed by a limiting membrane which fits either tightly or loosely. The Ec-U-cells have electron dense and polymorphous granules but do not contain a dense core in the limiting membrane. The ratio of Ec-T-cells to Ec-U-cells in the antral mucosa with intestinal metaplasia seems to be almost equal in gastric ulcer but smaller in gastric cancer. 2) Cell type W-cell in the normal antral mucosa has three kinds of granules; electron dense granules (100-200 mμ in diameter), granules (about 400 mμ in diameter) which have cloud-like or bubble-like substances in the limiting membrane, and granules which are empty-looking in the limiting membrane. In gastric ulcer cases, the W-type cells were apt to be granulated but there were no increse in the number. On the contrary, in atrophic gastritis, the W-type cells had low electron dense granules which were empty-looking in the limiting membrane. en-copyright= kn-copyright= en-aut-name=NabeyamaAkira en-aut-sei=Nabeyama en-aut-mei=Akira kn-aut-name=鍋山晃 kn-aut-sei=鍋山 kn-aut-mei=晃 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue=7-8 article-no= start-page=235 end-page=245 dt-received= dt-revised= dt-accepted= dt-pub-year=1971 dt-pub=19710830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cytological Studies on the Endocrine Cells in the Mucosa of Human Stomach Part T.

According to their fine structural characteristics, they were classified into the following five types. 1) Cell-type U is triangular in shape. The granules are round and vary in diameter (300-600mμ) and in electron density. 2) Cell-type V is triangular in form and has many grnules (130mμ in diameter) with high electron density. These granules are characterized by their uniform size and homogeneous appearance. 3) Cell-type W contains a prominent endoplasmic reticulum in the supranuclear region. These kinds of granules are recognizable in the basal part: smaller ones (100-200mμ), which are dense, larger ones (400mμ) which are pale and another larger ones (400mμ) which are empty-looking. 4) Cell-type Xis contact with the glandular lumen and contains numerous secretory granules with various densities. 5) Cell-type Y is oval in shape and characterized by small granules (100-150mμ) with moderate density, localized in the basal region. This cell type seems to have some features of an immature endocrine cells. en-copyright= kn-copyright= en-aut-name=NabeyamaAkira en-aut-sei=Nabeyama en-aut-mei=Akira kn-aut-name=鍋山晃 kn-aut-sei=鍋山 kn-aut-mei=晃 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue=7-8 article-no= start-page=229 end-page=233 dt-received= dt-revised= dt-accepted= dt-pub-year=1971 dt-pub=19710830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Morphological Changes of SV40 induced hamster tumor cells in vitro kn-title=SV40誘発腫瘍細胞の長期培養による変化について en-subtitle= kn-subtitle= en-abstract= kn-abstract=SV 40 induced hamster tumor cells were cultured in vitro for long terms.

The regional myocardial blood flows in the inner-(subendocardial) and outer-(sub-epicardial) layer were continuously monitored by heated cross-thermocouples designed according to Grayson's heat exchange principle. The techniques used were essentially the same as that described by Uchida (1970). The antianginal drug (nitroglycerin, 20 μg/Kg; prenylamine, 1 mg/Kg; dipyridamole, 0.3 mg/Kg; or dilazep, 0.2 mg/Kg) was administered intravenously. The results were as follows: (1) No difference in the regional myocardial blood flow between the inner- and outer-layer was observed. The flow ratio of the inner- to the outer-layer (I/O ratio) was 0.97±0.17. (2) Nitroglycerin produced a slight decrease in the flow through the inner-layer in spite of a remarkable drop in coronary perfusion pressure, while it did a marked decrease through the outer-layer. As the result, I/O ratio was significantly elevated after the injection. (3) Prenylamine produced a moderate increase in the flow through the both layers in spite of a remarkable fall in the coronary perfusion pressure. The ratio was rather elevated after a significant initial decline. (4) Dipyridamole caused a marked increase in the flow through the both layers, whereas I/O ratio was only minimaly lowered. (5) A change similar to that caused by dipyridamole was observed except a slight elevation of the ratio from 20 to 30 minutes when dilazep was injected. As mentioned above, these anti-anginal drugs produced different effects on the flow in the both layers. One of the explanation of these differences observed might be that these drugs have different effects on sites of coronary vessels, large intramural conductive vessels or small resistive vessels. Another explanation could be that these drugs cause different effects on the systemic hemodynamics. For the studies on effect of anti-anginal drugs on the intramyocardial distribution of blood flow, it is necessary that the regional myocardial blood flow must be monitored continuously since the intramyocardial distribution of the blood flow can be changed from time to time after the administration. en-copyright= kn-copyright= en-aut-name=HiranoKazuhiro en-aut-sei=Hirano en-aut-mei=Kazuhiro kn-aut-name=平野和博 kn-aut-sei=平野 kn-aut-mei=和博 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=593 end-page=604 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Exercise electrocardiographic studies on left ventricular hypertrophy in essential hypertension kn-title=本態性高血圧症による左心室肥大心電図と運動負荷心電図 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The exercise electrocardiogram of the patients with left ventricular hypertrophy was studied, especially on its STT change. Seventy six patients with essential hypertension, who were under good control, were included for the study. They were 52 males and 24 females. Their ages ranged from 33 to 70 years (the average was 51.6±7.8 years of age). The patients were divided into four groups according to changes in ST segment and T wave on standard 12 lead ECG (V, aVR were excluded): Group A consisted of 10 subjects, whose ECG showed so-called "Strain Pattern"; Group B included 22 subjects, showing ischemic depression less than 0.5 mm below the isoelectric line or low T wave (T/R≦1/20 and R≧10mm); Group C included 17 subjects, junctional depression was equal to or exceeded 1.0 mm; Group D included 27 subjects without marked STT change. Twenty healthy men (6 males and 14 females) were studied as control. They ranged in age from 20 to 62 (the average was 36.7 ± 14.1 years of age). As a rule, they were subjected to the Master's test (double two step). In the pre-exercise electrocardiogram of Group A, QRS voltage, LAD and QT ratio were significantly greater than any other groups. In the post-exercise electrocardiogram, Group A showed chiefly T wave changes without ST deviation. I could not find any cases in the group with positive responce. Therefore, the "Strain Pattern" with marked QRS high voltage might be secondary STT changes. On the other hand, patients in Group B and D showed mainly ST changes and most of them were determined to have positive responce of the test. So, the STT changes without marked QRS high voltage might be primary changes. en-copyright= kn-copyright= en-aut-name=MinatoTakeshi en-aut-sei=Minato en-aut-mei=Takeshi kn-aut-name=湊武 kn-aut-sei=湊 kn-aut-mei=武 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=571 end-page=591 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Serum dopamine-β-hydroxylase activity in manic depressive psychosis kn-title=躁うつ病における血清ドーパミン-β-水酸化酵素活性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The serum DBH (Dopamine-β-Hydroxylase) activity in a total of 177 individuals was determined in this study during the period from June 1974 to June 1975. The subjects were 103 manic-depressive psychosis patients and 43 patients with other diseases who had visited the Neurology Department of the Hiroshima City Hospital and 31 healthy subjects included for comparison. Among the 103 manic-depressive psychosis cases, there were 55 cases, 40 with unipolar depression and 15 with bipolar depression, in whom determination of activity was made during both the depressive and remission phases. Further, in 25 unipolar depression and 6 bipolar depression cases, the diurnal variation of activity was measured and studied in detail. The following results were obtained from the above findings. 1. There was marked individual difference in serum DBH activity. Great individual difference was observed in healthy persons also, but in the same individual the value obtained by repeat test perform 9 months after the initial test showed almost the same result and the rate of variation was less than ± 10% . 2. Comparison of the mean values of serum DBH activity among various diseases showed the values to be high in the order of schizophrenia, neurosis, unipolar depression and bipolar depression, but the differences from healthy persons were not significant. 3. Variation in serum DBH activity in manic-depressive psychosis strongly suggested the heterogeneity of unipolar and bipolar depressions. Further it was also assumed that there were heterogeneous diseases mixed among the unipolar or bipolar depression cases, and thus further subclassification was performed. 4. Cases with unipolar depression were classified into 3 groups according to whether the differece in value of serum DBH activity was significantly higher in the depressive phase than the remission phase (Group T), unchanged (Group U) and significantly lowere (Group V). The respective clinical characteristics were as follows: Group T consisted of 40% of the unipolar depression cases, was made up predominantly of women and a strong feeling of anxiety prevailed, but the subjects responded well to tricyclic antidepressants. Group U was composed of 32.5%, the subjects were highly irritant and many did not respond well to tricyclic antidepressants. Group V consisted of 27.5%, was made up predominantly of males, severe psychomotor retardation was present and the subjects responded well to tricylic antidepressants. 5. All cases with bipolar depression presented the characteristic finding of lower activity values during the depressive phase than the remission phase. Cases with manic phase activity values lower than the remission phase were classified as Group T and those with higher values Group U. The respective clinical characteristics were as follows: Group T was composed of 69.2% of the bipolar depression cases of whom many changed to mania within a short period of time after their depressive phase making it appear as if the depressive and manic phases were one single continuous phase. Group U was composed of 30.8% and was frequently found in those with a marked manic phase only or in those whom the manic or depressive phase developed independently. 6. The diurnal variation of serum DBH activity in manic-depressive psychosis was not of a fixed pattern such as being low in the morning and high at noon. However, many presented a similar rhythm for both the depressive and remission phases of the disease, but the rate of diurnal variation was greater during the depressive or manic phase than the remission phase. The rate of diurnal variation during the remission phase was about ± 10%. en-copyright= kn-copyright= en-aut-name=MoritaHironori en-aut-sei=Morita en-aut-mei=Hironori kn-aut-name=森田博方 kn-aut-sei=森田 kn-aut-mei=博方 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=社会保険・広島市民病院・神経科 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=553 end-page=570 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the antigenicity of lymphocyte membrane PartU Immunizing experiment on mice kn-title=リンパ球膜の抗原性に関する研究 第2編 マウス感作実験 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Further investigation concerned on the antigenicity of the lymphocyte membrane was performed in this paper using C57B1 mice and purified lymphocyte membranes which were preparated from either calf thymic lymphocyte (TM) or bovine intestinal lymphnode lymphocyte (LM). The detail of the methods for the purification of lymphocyte membrane were described in the part T of this article. Intraperitoneal injection of 5, 10 or 100γ of lymphocyte membrane was performed once a week untill 5 weeks. The peripheral blood pictures, diameter of lymphocyte, histological studies on the thymus, lymphnode and spleen, serum protein electrophoresis, immunoelectrosyneresis, RFC and PHA reactivity were examined in these immunized mice. The lymphocytes both in the peripheral blood and lymphatic organs were diminished profoundly in the mice immunized with TM. Especially the lymphocytes in the T dependent area of spleen and lymphnode as well as in the cortical area of the thymus decreased intensively in contrasting with a decrease of B cell area of spleen and lymphnode in the mice immunized with LM. The lymphocyte depletion in the lymphoid organs of the mice immunized with 100γ LM had a similar pattern to those of mice immunized with TM indicating the contamination of TM into the LM preparation up to approximately 6-8%. Temporary increase of α1-globulin, α2-globulin and α3-globulin in this order was noted in serum of the mice immunized with TM, being followed by hypergammaglobulinemia. On the other hand an increase of α3-globulin and then of γ-globulin appeared rapidly in the mice immunized with LM. The discrepancies on the tissue reaction and protein fraction of these two groups suggested the difference of antigenicity between TM and LM on the activation of antibody-forming system. en-copyright= kn-copyright= en-aut-name=KobashiHidehiro en-aut-sei=Kobashi en-aut-mei=Hidehiro kn-aut-name=小橋秀広 kn-aut-sei=小橋 kn-aut-mei=秀広 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=545 end-page=551 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Immunological studies on chronic myelogenous leukemia Part U.

The following data were obtained: 1) The 19 patients, whose serum immunoglobuline levels were examined, were all within normal range with mean values of IgA 203±74mg/dl, IgG 1463±275mg/dl and IgM 182±67mg/dl. 2) IAHA was positive in 4 of 24 patients (16.7%) and the reactivity was correlated with the number of peripheral leukemic cells used as antigen; it was positive in 3 of 9 patients (33.3%) with leukemic cells over 4×10(4)/μ 1, but in only one of 15 patients (6.7%) with leukemic cells below 4×10(4)/μ 1. The IAHA test was also correlated with the disease state; none of 4 patients (0%) during blastic crisis of CML showed a positive reaction to their own leukemic cells. 3) Sera from 12 of 17 patients (70.6%) showed a positive lymphocytotoxicity to normal lymphocytes. In its correlation with the disease state, it was positive in 8 of 13 patients (61.5%) during remission and in all the patients (100%) during relapse. From these results it could be concluded that humoral immunity in CML is not so impaired through the clinical course except for blastic crisis. en-copyright= kn-copyright= en-aut-name=ChenPo-min en-aut-sei=Chen en-aut-mei=Po-min kn-aut-name=陳博明 kn-aut-sei=陳 kn-aut-mei=博明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=535 end-page=543 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Immunological studies on chronic myelogenous leukemia Part T. Cell-mediated immunity in chronic myelogenous leukemia kn-title=慢性骨髄性白血病の免疫学的研究 第一編 細胞性免疫の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cell-mediated immunity in chronic myelogenous leukemia (CML) was investigated by means of three kinds of skin tests, including purified protein derivated of tuberculin (PPD), candida and dinitrochrolobenzene (DNCB), and macrophage migration inhibitory test (MIT). Immunological examinations were made on 21 patients with CML, who have been admitted to our hospital or controled in our outpatient department since October 1974, at the same, 20 healthy adults were used as control study. The following results were obtained: T. Skin tests: 1) Thirteen (61.9%) of 21 patients showed positive reactions to the PPD at least once throughout clinical course of each patient, while positive in 18 (90.0%) of 20 controls. 2) Candida test was attempted on a total of 13 patients. One (7.7%) of these 13 patients showed positive reaction to the candida, while positive in 9 (45.0%) of 20 healthy subjects. 3) Seven (41.2%) of 17 patients showed positive reactions to the DNCB sensitization, while all of 20 controls proved to be positive. 4) The results of PPD skin test were analyzed according to the stages in clinical course of each individual. Positive reactions were obtained from 50% of the patients at pretreatment stage, 66.6% at remission stage, 20% at relapse stage and 16.6% at blastic crisis. 5) The PPD skin test changed from negative, or false positive, to positive in 5 of 21 cases who had achieved remission during the observation period, while it changed from positive to negative in one case who had relapsed during the same period. It kept positive in 4 of 8 cases who had maintained remission, and kept negative in one relapsing case having failed to achieve remission. In 2 of 6 cases who had a blastic crisis during the observation period, it was positive before the crisis and became false positive after the crisis. According to these results a significant correlation was found between PPD and clinical stage of CML. U. Macrophage migration inhibitory test (MIT): 1) In the preliminary studies, the optimal ratio was determined that 10(6) lymphocytes react properly to 0.1ml antigen fluid, which is equivalent to 0.11-0.03μ g of protein level and is extracted from the leukemic cells by means of sonication. 2) Eight (53.3%) of 17 patients were regarded as positive in allo-antigen system of MIT and 5 (55.5%) of 9 patients in auto-antigen system. Because of the difficulty of collecting lymphocytes, all MIT were conducted only in the remission stage of each patient. From these results, the following conclusion can be made. Cellular immunity in CML is somewhat impaired at pretreatment or relapsing stage. It is, however, repaired mostly at remission stage and it has a close correlation to clinical stage of CML. en-copyright= kn-copyright= en-aut-name=ChenPo-min en-aut-sei=Chen en-aut-mei=Po-min kn-aut-name=陳博明 kn-aut-sei=陳 kn-aut-mei=博明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=527 end-page=534 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A report of field survey on acatalasemia and hypocatalasemia in 1972 and 1973 kn-title=昭和47年度および48年度 Acatalasemia, Hypocatalasemia 調査集計 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The authors reported the results of field survey on acatalasemia and hypocatalasemia during the year of 1972 and 1973.

By the light microscopy it was found that in the case of the intraperitoneal injection of H(3)-thymidine, S(35)-DL-cysteine and S(35)-H(2)SO(4) into mice, most of siliver particles deposit in the cytoplasm and nucleus of spheroid alveolar cells. In observing this phenomenon by the electron tracers, the above tracers enter not only into the nucleus but also into mitochondria, degenerated mitochondria, and into inclusion bodies of myelin-type or lamellar microbodies in the cytoplasm of the spheroid alveolar cells. From these results it is understood that the inclusion body not clarified at present is formed by the degeneration of mitochondria. This inclusion body seems to be a kind of cytolysomes and by various enzymes contained in it, nucleic acids, proteins, mucopolysaccharides, phosphoric acid ester, and glucuronide are dissolved and finally they are reduced into the myeline figure substance as the endproduct. The endproduct is to be secreted into the alveolar lumen from the spheroid alveolar cell. en-copyright= kn-copyright= en-aut-name=SuwaKiichi en-aut-sei=Suwa en-aut-mei=Kiichi kn-aut-name=諏訪喜一 kn-aut-sei=諏訪 kn-aut-mei=喜一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部解剖学教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=505 end-page=513 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Light and electron microscope observations of the structures of the elastic components in the arterial wall and their functional, structural mechanism kn-title=動脈壁の弾性成分の構造の光顕的ーと電顕的検査及びその構造の機能的形成機序について en-subtitle= kn-subtitle= en-abstract= kn-abstract=From both the light and electron microscope observations of histological structure and mechanisms of contruction of arterial wall, the functional, formative mechanisms of elastic membrane of arterial wall may be explained as follows: The fundamental type of artery is the muscular-type artery in which the chain of smooth muscle cells runs criss-cross wise from left to right or vice versa in Archimedes spiral formation as viewed from the upper surface. That further differentiates and the chain disintegrates, resulting in individual smooth muscle cells bridging between the elastic membranes to form an elastic-type artery. In the case of the muscle-type artery of a relatively high differentiation, the smooth muscle cell chain is divided into equal parts each of which forms an individual Archimedes segment composed of original elastic components. In the case of elastic-type artery within such a segment, cells become individual smooth muscle cells. The elastic component ejected from the cytoplasm of each smooth muscle cell forms the elastic fiber sheath by its kinetic movement. This sheath in the muscle-type is divided into two equal numbers in the center of the above segment, and longitudinal sheath-segments of about one fourth of the original size separate to left and right, then at the horizontal level they form Archimedes segments with the original elastic networks by attaching themselves to the anterior-posterior surfaces and the lateral surface. However, only the inner layer of the internal elastic membrane is formed by the elastic prefibers of high ascending angle produced by endothel cells. In the case of elastic-type artery, the elastic sheath containing the individual smooth muscle cell is similarly divided into two equal parts at the center, which are further split up longitudinally that reinforce the original elastic network to form an elastic membrane. In each elastic sheath there are formed a spiral ascending fiber in the direction of the longitudinal axis and a fiber of approximately circular shape, the former of which becomes an ascending fiber and the latter becomes the longitudinal fiber of the elastic membrane. Therefore, the ascending angle of fiber of the elastic membrane is equal at the opposite surface of the stroma. In addition, the reason why the ascending angle of fiber is higher in the outer-layer fiber than in the inner-layer fiber is because the twisting phenomenon by contracting movement of the smooth muscle cells is stronger in those of the outer layer and the ascending angle of the fiber of elastic sheath is lower in the outer side. en-copyright= kn-copyright= en-aut-name=SuwaKiichi en-aut-sei=Suwa en-aut-mei=Kiichi kn-aut-name=諏訪喜一 kn-aut-sei=諏訪 kn-aut-mei=喜一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部解剖学教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=497 end-page=504 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Light and electron microscope observations of the structures of elastic-type artery and muscular-type artery and their functional, formative mechanism kn-title=弾性型動脈と筋型動脈の光顕的ーと電顕的検査及びそれらの構造の機能的形成機序 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The arterial wall is all consisted of the chain of fibroblasts that run stereoscopically crisscrossing with each other in the Archimedes spiral formation, as viewed from the upper surface, originating from the endothel cells in the initial embryonic stage, and also with the heterogenous fibroblasts that continue in the same spiral direction. The endothel cells form the elastic prefibers of the subendothelial layer, while the fibroblasts of tunica media which form Archimedes spiral, construct elastic and collagenous fibers and transform into smooth muscle cells. On the other hand, heterogenous fibroblasts construct collagenous and elastic fibers of tunica adventitia. This chain of the smooth muscle cells of tunica media that retains Archimedes spiral, as viewed from the upper surface, is the muscular-type artery and the one that has differentiated and each smooth muscle cells have bridged between elastic membranes is the elastic-type artery. en-copyright= kn-copyright= en-aut-name=SuwaKiichi en-aut-sei=Suwa en-aut-mei=Kiichi kn-aut-name=諏訪喜一 kn-aut-sei=諏訪 kn-aut-mei=喜一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部解剖学教室 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=7-8 article-no= start-page=493 end-page=496 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Theoretical study on the structural mechanism of the valves of the venous and thoracic duct wall kn-title=静脈壁と胸管壁の弁膜の形成機構についての理論的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The height, the size and the interval space of the valves of the vena saphena magna and the ductus thoracicus of adult dogs were measured.

In man, three positive and three negative waves, namely T-P, T-N, U-P, U-N, V-P and V-N, were observed as cortical evoked responses after single stimulation of the ventrolateral thalamic nucleus. And W-P and W-N were observed after the stronger stimulation which could provoke augmenting response with the repetitive volley. Later components of evoked cortical responses were investigated in cat immobilized under local anesthasia. Recording electrole was located on the anterior sigmoid gyrus. As the intensity of the thalamic stimulation was increased, afterdischarges of the negative waves, which appeared with long latency (about 200 msec.), increased in number and developed into spindle-like pattern with notches on afterdischarges. The long latencied negative wave in cat and W-N in man were considered to correspond to Lehtinen's "precursor of the evoked spindle activity". It has been already reported by Miyamoto that W-N was supposed to play an important role in augmenting response in man. Close relationship was indicated between augmenting response and spindle-like afterdischarges. Futhermore, the similarities of the pattern between spindle-like afterdischarges following thalamic stimulation and spontaneous spindle waves in cat, and attenuation of ipsilateral spontaneous spindle waves after destruction of the ventrolateral thalamic nucleus in cat as well as in man were also observed. From these facts these cortical synchronized activities, namely AR, spindle-like afterdischarges and spontaneous spindle waves were considered to be brought by similar neuronal mechanism with some varieties of synchronization ascribed to arousal levels under influences of activities of the ventrolateral thalamic nucleus. On the other hand, spindle-like afterdischarges and spontaneous spindle waves in cat were analized for investigating their waxing and waning phenomena. Notches were observed on each waves. When the wave grew with maximal amplilude in a train of spindle, the notch of the wave became obscure. The phenomenon was considered that the notch was synchronized with the wave, forming maximal amplilude of the wave in a train of spindle. In other words, mechanism of this phenomenon was supposed to be explained as a beat of two rhythmic activities slightly different in frequency. en-copyright= kn-copyright= en-aut-name=BeckHiroichi en-aut-sei=Beck en-aut-mei=Hiroichi kn-aut-name=別宮博一 kn-aut-sei=別宮 kn-aut-mei=博一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学脳神経外科教室 END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=7-8 article-no= start-page=363 end-page=371 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Guanidino Compounds in Brain by Automatic Liquid Chromatography kn-title=液体クロマトグラフィーによる脳グアニジノ化合物の分析に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1.

These studies reveal that changes in serum α(1)-AG levels during chemotherapy would be an index to the efficacy of chemotherapeutic agents for malignant neoplasms because it has been shown that α(1)-AG levels changed in intimate relation to neoplastic processes in almost all the cases of lung or stomach cancer. Especially, in malignant lymphoma, changes in α(1)-AG levels during the clinical course showed such a close relation to vicissitudes of lymphadenopathy that serial determinations of this glycoprotein was regarded as a reliable index not only for the efficacy of chemotherapy but also for the early detection of relapse prior to the manifestations of clinical symptoms. On the other hand, changes in α(1)-AT levels did not correlate to the progression of canecrous lesions in almost half the cases recieving various chemotherapeutic agents and corticosteroids. It was considered that these agents, especially corticosteroids, might be directly concerned with metabolism of this glycoprotein. In patients with lung or stomach cancer who did not obtain any clinical improvement during chemotherapy, significant correlation was observed between α(1)-AG as well as α(1)-AT levels prior to chemotherapy and their life spans. Therefore, it was possible to set up a regression line of life spans against these glycoprotein levels and life spans of ineffective cases to chemotherapy could be estimated roughly according to this regression line. en-copyright= kn-copyright= en-aut-name=OnoshiTaisuke en-aut-sei=Onoshi en-aut-mei=Taisuke kn-aut-name=大熨泰亮 kn-aut-sei=大熨 kn-aut-mei=泰亮 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科 END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=7-8 article-no= start-page=331 end-page=348 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical Studies on Serum Glycoproteins in Patients with Malignant Neoplasm Part T.

An almost parallel increase of these glycoproteins was observed in patients with advanced cancer except hepatoma, but in cases with localized lesion these serum levels remained normal. In 85 patients with lung cancer and 49 with stomach cancer, considerable relationship was observed between the serum levels of these glycoproteins and degree of progression of cancerous lesions. Therefore, it seems that these glycoprotein levels are a relible index for staging malignant diseases. In Hodgkin's disease, however, there was no relationship between these serum levels and its clinical stage, but these glycoprotein levels in B cases of Hodgkin's disease were significantly elevated than in A cases. Evaluation of these glycoproteins would serve as a diagnostic means in patients with hepatomegaly and/or jaundice, since in patients with hepatoma α(1)-AG levels are decreased and α(1)-AT levels are elevated, in patients with metastatic liver cancer both of them are significantly elevated and in cirrhosis of the liver α(1)-AG levels are clearly decreased and α(1)-AT levels remain normal. en-copyright= kn-copyright= en-aut-name=OnoshiTaisuke en-aut-sei=Onoshi en-aut-mei=Taisuke kn-aut-name=大熨泰亮 kn-aut-sei=大熨 kn-aut-mei=泰亮 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科 END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=7-8 article-no= start-page=323 end-page=330 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Two Cases of Crohn's Disease kn-title=Crohn病の2症例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We encountered a 24-year old female with a swelling and severe pain in the hypogastric region as her main complaints and another 32-year old male with hypogastric pain persisting for several years as main complaint.

Four lines of tissue culture cells were obtained. A-419 and A-319 lines of cells were obtained from the fourth transplant generation of the tumor (adenocarcinoma), A-600 line of cells were obtained from the 26th transplant generation of the tumor (sarcomatous), and A-162 line of cells were from the adenocarcinoma produced by back-transplantation of primary culture cells of A-419 line cells to AKR mice. These four lines of tissue culture cells showed similar morphology and distribution, mixed growth of both epithelial cells and fibroblastic cells. Back-transplantation of primary culture cells of A-419 and A-319 lines to AKR mice produced adenocarcinomas, but A-319 line cells of later passages (28th, 29th, 31st, and 35th passage) and A-600 line cells produced sarcomas when transplanted back to AKR and C(3)Hf mice. Two mechanisms have been proposed to explain the sarcomatous transformation; 1) transformation of carcinoma cells to sarcoma cells and 2) malignant change of interstitial connective tissue cells during serial passages of the culture cells. The second mechanism was considered to be most probable in the present case. en-copyright= kn-copyright= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name=原田英雄 kn-aut-sei=原田 kn-aut-mei=英雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学第二内科 END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=7-8 article-no= start-page=297 end-page=306 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Spontaneous Mammary Carcinoma of Low Cancer Strain AKR Mice T Electronmicroscopic Studies on Virus Particles in Primary and Serially Transplanted Tumors kn-title=乳癌嫌発系AKRマウスに自然発生した乳癌に関する研究 第1編 原発腫瘍および動物継代移植腫瘍に観察されたウィルス粒子の電子顕微鏡的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This report is concerned with histological and electronmicroscopic studies on a spontaneous mammary carcinoma of AKR mice which are known to be high leukemic and low cancer strain. Followings are the conclusions obtained. 1) The spontaneous mammary carcinoma was type B adenocarcinoma according to Dunn's classification. The histology was similar to those frequently observed in mammary carcinoma of high cancer strain of mice such as C(3)H, RIII, and DBA mice. Electronmicroscopic studies revealed many type A virus particles around the cytoplasmic vacuoles or free in the cytoplasm, and numerous type B virus particles In the acinar spaces. In addition, a few type B virus particles were observed in the cytoplasmic vacuoles and in the intercellular spaces. Morphology, distribution, and formation process of these virus particles were similar to those observed in mammary carcinoma of high cancer strain of mice and some of low cancer strain of mice. These results indicate that there exist "milk factor" in low cancer strain of mice as well as in high cancer strain of mice and that the factor can induce mammary carcinoma even in low cancer strain of mice when hormonal and other environmental factors are abequate. 2) Serial electronmicroscopic observations of the original and serially transplanted mammary carcinoma of AKR mice disclosed a gradual decrease in numbers and only a few immature type B virus particles were observed after the 21st generation. These findings were ascribed to the sarcomatous transformation and loss of acinar spaces observed during the serial transplantation of the original mammary carcinoma.. 3) The original mammary carcinoma of AKR mice harbored numerous type A and type B virus particles. Type C particles, however, were hardly observed. In tissue culture cells derived from the tumor, in contrast, numerous type C virus particles were observed and type B virus particles were hardly found.

By the passive transfer of sensitized spleen cells, there could be detected the infiltration of round cells in Glissons capsule and sinusoid of the liver and in a few cases liver cell necrosis mainly of piecemeal necrosis. In the subsequent observations on blood anti-liver antibody, intratissue γ-globulin as well as the localization of anti-liver antibody, there could be recognized no significant corre lations to the above-mentioned histological changes of liver, but in the culture of sensitized rat peripheral lymphocytes conductes in the presence of liver antigen there was observed a significant blast-like transformation as compared with control group. From these experimental results with rats it seems that the lymphoid focus and piecemeal necrosis observable in Glissons capsule of the liver in human liver diseases can also be said fairly safely to be the histological expression of auto-immune phenomenon. en-copyright= kn-copyright= en-aut-name=OkaKanji en-aut-sei=Oka en-aut-mei=Kanji kn-aut-name=岡莞爾 kn-aut-sei=岡 kn-aut-mei=莞爾 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=7-8 article-no= start-page=265 end-page=276 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the induction and development of lymphosarcoma by N-Nitrosobutylurea in RF Mice. 2.

In other words, the administration of MCA reduces the PFC number of spleen cells in mice and it markedly suppresses the immunological activity of normal mice. This indicates that MCA is appreciably involved in the immunity to carcinogenesis. On the other hand, the activity of allogeneic inhibition in the precancerous stage is maintained during the period between MCA administration and the time of cancer development. However, the allogeneic inhibition activity decreases by 8 weeks after MCA administration, the time when the tumor has grown to the size macroscopically visible. This finding suggests that the activity of the allogeneic inhibition is associated more with the proliferation rather than with oncogenesis. en-copyright= kn-copyright= en-aut-name=TeradaNorihiko en-aut-sei=Terada en-aut-mei=Norihiko kn-aut-name=寺田紀彦 kn-aut-sei=寺田 kn-aut-mei=紀彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科教室 END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=7-8 article-no= start-page=231 end-page=240 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Anticancer Activity of Lymph Node Cells on Primary Cultured Tumor Cells Derived from Human Cancers kn-title=人癌由来初代培養細胞に対する人リンパ節細胞の抗増殖性に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study was conducted to determine the concomitant immunity in cancer patients by culturing lymph node cells obtained from various cancer patients with the primary cultured tumor cells derived from human cancer and the following results were obtained. 1. The primary cultures were conducted with 42 cases of gastric cancer, 12 of mammary cancer, 8 of cancerous thoracic fluid, 5 of cancerous ascites, 2 of metastatic hepatoma, 2 of thyroid cancer and 7 others. Among them there were 29 cases where the sufficient number of free cells were obtained by the same type of culture so that there were enough viable tumor cells attached on the culture vessel wall to harvest. 2. Effects of autochthonous lymph nodes on human primary cultured cancer cells : From the total of 22 cases comprising 9 cases of gastric cancer, 6 of mammary cancer, 2 of metastatic hepatoma, one of thyroid cancer, 2 of cancerous thoracic fluid and 2 of cancerous ascites, 30 series of cytotoxicity tests were conducted by mixing each of them with autochthonous lymph node cells mainly prepared with lymph nodes obtained at surgical operation. During the mixed culture for the period of 24 hours to 72 hours the cases where the autochthonous lymph node cells had shown anti-proliferative effect on the primary cutured cells amounted to 12/30 cases (70%), and those that showed a proliferative effect instead amounted to 1/30 cases (3.3%). 3. Effects of autochthonous lymph nodes according to their sites on human primary cultured cancer cells : Considering the sites of tumors, the lymph nodes collected were roughly divided into the regional lymph nodes and distant lymph nodes, and looking at their anti-proliferative effect 7/13 cases (54%) of the regional lymph nodes and 14/17 cases (82.4%) of the distant lymph nodes had shown the anti-proliferative effect. 4. Effect of allogeneic lymph nodes on the primary cancer cells derived from human patients: There were 30 lines of mixed cultures of allogeneic lymph node cells and the human primary cultured cancer cells, and of them 11/30 cases (36.7%) showed anti-proliferative effect. By dividing lymph nodes according to cancer patients and non-cancer patients 8/16 cases (50%) in the former had anti-proliferative effect while 3/14 cases (21.4%) in the latter group. From these findings it may be said that there is concomitant immunity established in human cancer and lymph nodes act inhibitorily on tumor. Moreover, most cases having larger tumors are in the terminal stage of cancer, and there can be observed a decrease-disappearance of immunity of regional lymph nodes in such cases. en-copyright= kn-copyright= en-aut-name=KobayashiMasami en-aut-sei=Kobayashi en-aut-mei=Masami kn-aut-name=小林雅己 kn-aut-sei=小林 kn-aut-mei=雅己 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学第一外科 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=697 end-page=706 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on bilirubin sulfate Part 2.

Forty-three examined cases were consisted of eight cases with cholecystopathy, seven cases with acute hepatitis, nine cases with chronic hepatitis, seven cases with cirrhosis of the liver, four cases with Gilbert's syndrome and eight normal subjects, and their bile were collected with duodenal tube. The sulfate radical in direct bilirubin was quantitatively determined by Weber & Schalm's method and the molar ratio of sulfate radical to bilirubin was calculated. The following results were obtained. 1) No difference was observed between male and female, and among the age of patients on the molar ratios of sulfate to bilirubin. 2) The molar ratio of glucuronic acid to ester-form bilirubin was inversely proportional to that of sulfate radical to direct bilirubin. 3) The mean molar ratio of sulfate radical to direct bilirubin was found to be 0.10 in normal subjects, 0.08 in the cases with cholecystopathy, 0.27 in chronic hepatitis, 0.39 in acute hepatitis, 0.51 in liver cirrhosis and 0.48 in Gilbert's syndrome. The each values of liver diseases was significantly higher than normal subjects, and no difference between normal subjects and the cases with cholecystopathy. 4) Significant correlation was observed between the molar ratio of sulfate radical to direct bilirubin and following items, that is, ZnTT, TTT and γ-globulin; but no correlation between the molar ratio of sulfate radical to direct bilirubin and S-GOT, S-GPT, serum alkaline phosphatase, serum bilirubin and BSP retention test. These results suggest that the sulfate conjugation of bilirubin was compensated as compared to the disturbance of glucuronide formation of bilirubin in liver parenchymal damage. en-copyright= kn-copyright= en-aut-name=WatanabeYutaka en-aut-sei=Watanabe en-aut-mei=Yutaka kn-aut-name=渡部寛 kn-aut-sei=渡部 kn-aut-mei=寛 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=687 end-page=696 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on bilirubin sulfate Part T. The ability to excrete bilirubin sulfate into bile in the heterozygote Gunn rat kn-title=硫酸抱合型bilirubinに関する研究 第1編 Heterozygote Gunn ratの胆汁中への硫酸抱合型bilirubinの排泄能 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The nature of biochemically synthetic bilirubin sulfate was examined on detail, and bilirubin sulfate and bilirubin glucuronide were measured in bile of heterozygote Gunn rat and Wister strain rat. Further, after the intrvenous injection of (3)H-bilirubin sulfate into heterozygote Gunn rats and Wister strain rats, the biliary excretion rate of bilirubin sulfate was studied in them. The following results were gained by these studies. 1) The absorption peak was 452 nm in the synthetic bilirubin sulfate solution, pH 2.2, and its azo pigment showed each peak absorptions at 535-545 nm in pH 2.0 and at 565-575 nm in pH 1.0. The molar ratio between bilirubin and sulfate in the band of thin layer chromatography showing an Rf of 0.26 was determined from 1.72 to 1.96 with a mean of 1.78±0.09 S.D.. These data suggest that this compound is bilirubin disulfate. 2) In the bile of Gunn rats and Wister strain rats, the molar ratio of glucuronic acid to esterfrom bilirubin was inversely proportional to that of sulfate radical to direct bilirubin (r=-0.74, p<0.05). This implies that the conjugation of bilirubin with sulfate increases compensatedly as compared to the disturbance of that of bilirubin with glucuronic acid. 3) The excretion ratios of 2 hours to 24 hours in the intravenous (3)H-bilirubin sulfate loading were 54.2% in Gunn rats and 63.4% in Wister strain rats. This finding supports the concept that bilirubin sulfate is easily excreted in the bile. The biliary excretion within 24 hours following the administration of bilirubin sulfate was 40.4% in Gunn rats and 69.4% in Wister strain rats, and these excretion rates decreased in parallel with the decrease of molar ratio in bilirubin glucuronide (r=0.96, p<0.01). It is suggested that the ability to excrete bilirubin sulfate may be the limiting factor in the existence of defective hepatic bilirubin glucuronidation. en-copyright= kn-copyright= en-aut-name=WatanabeYutaka en-aut-sei=Watanabe en-aut-mei=Yutaka kn-aut-name=渡部寛 kn-aut-sei=渡部 kn-aut-mei=寛 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=673 end-page=686 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical and experimental studies on guanidino compounds in uremia kn-title=尿毒症におけるグアニジノ化合物に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1) Eleven guanidino compounds were successively isolated and determined in uremic serum and brain by liquid chromatography using the cation-exchange resin (LCR-2, Jelco) and selecting the proper buffer system for elution. 2) The concentration of total guanidino compounds, including arginine, taurocyamine, glycocyamine, and guanidinosuccinic acid etc., was 143±39nmoles/ml in normal human serum (BUN:7-20mg/dl). 3) The concentration of total guanidino compounds was 296±101nmoles/ml in serum of uremic patient (BUN: 40-161mg/dl). The concentration of taurocyamine and guanidinosuccinic acid were significantly elevated and methylguanidine was detectable in uremic serum. 4) Experimental uremia was induced by bilateral ureteral ligation of rabbit. Forty-eight hours after ligation when blood urea level rose to 90-219mg/dl, the concentration of guanidino compounds, especially taurocyamine and guanidinosuccinic acid, significantly increased. 5) The concentration of total guanidino compounds in norlnal rabbit brain was 359±37nmoles/g and that of γ-guanidino-β-hydroxybutyric acid and γ- guanidinobutyric acid were much higher than in serum. At forty-eight hours after bilateral ureteral ligation, significant increment of taurocyamine and decrease of glycocyamine and arginine were noted. The trace amount of methylguanidine was detected. 6) Generalized tonic and clonic convulsion was observed in the rabbit three minutes after intracisternal injection of methylguanidine (1.5mg/kg b. w.). Seizure discharges were recorded on electrocorticogram of the rabbit and cat, and it was comfirmed that spike activity originated in hippocampus on depth recordings. en-copyright= kn-copyright= en-aut-name=MatsumotoMichiko en-aut-sei=Matsumoto en-aut-mei=Michiko kn-aut-name=松本路子 kn-aut-sei=松本 kn-aut-mei=路子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳代謝研究施設機能生化学部門 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=661 end-page=671 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Statistical study on tympanoplasty and postoperative hearing gain. -Observations of cases operated for the past 10 years (1963-1972) in the Dept. of Otolaryngology, Okayama University- kn-title=岡山大耳鼻科教室における鼓室成形術の統計と術後聴力―昭和38‐47年の間の手術に関して― en-subtitle= kn-subtitle= en-abstract= kn-abstract=(1) Tympanoplasties were done on 956 ears (789 persons) in our clinic for the past 10 years.

The comparative study of the percentage of bilirubin phosphate fraction to the ester-form bilirubin and various liver function tests was investigated. Crude direct bilirubin was extracted from the jaundiced urine in the cases of liver diseases and fractionated into ester-form bilirubin by Kosaka-Hara's method and fractionated into three bilirubin fractions by the cellulose powder column chromatography with the solvent system of n- butanol, ethanol and water (4:1:2). The third fraction showed positive phosphate-ester reaction (bilirubin phosphate), and the glucuronic acid was negative in this fraction. 1. Percentages of bilirubin phosphate fraction to total ester-form bilirubin were 26.7 in the acute yellow liver atrophy, 11.27 in liver cirrhosis, 9.24 in the obstructive jaundice, 6.83 in the chronic hepatitis, and 6.09 in the acute hepatitis in each average, respectively. 2. Significant correlation could be found between the percentage of bilirubin phosphate fraction to the ester-form bilirubin and various liver function tests, that is, thymol turbidity test, zinc sulfate turbidity test and the percentage value of serum γ-globulin. 3. The decreasing tendency of the percentage of bilirubin phosphate fraction to the esterform bilirubin could be indicated the improvement of the liver function tests and the course of the disease. en-copyright= kn-copyright= en-aut-name=YamamotoTakehiko en-aut-sei=Yamamoto en-aut-mei=Takehiko kn-aut-name=山本武彦 kn-aut-sei=山本 kn-aut-mei=武彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=645 end-page=651 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on urinary bilirubin Part 1.

(3)H-bilirubin was prepared with Wilzbach's method. Crude direct (3)H-bilirubin was extracted from the rat bile after injection of (3)H-bilirubin dissolved in rat serum into the duodenal canal. Crude direct (3)H-bilirubin were fractionated into three bilirubin fractions named indirect, salt-form and ester-form bilirubin by Kosaka-Hara's method. Change of excretion rate of ester-form bilirubin into urine in various blood pH ranged from 6.4 to 7.4 was investigated from the point of bilirubin-protein binding. The results were as follows; 1. (3)H-radio activity in the urine was bound with the indirect bilirubin at the rate of 85.78% in average and with the ester-form bilirubin at the rate of 93.81% in average. 2. Ester-form bilirubin was excreted into the urine 1.69% in average by loading it to the renal portal vein, in the other hand, that of indirect bilirubin was 0.57% in average, in the first 5 minutes after loading. 3. Loading bilirubins to the renal artery, ester-form bilirubin was excreted into the urine, 10.60%, in average, indirect bilirubin was 0.08%, in average. 4. Excretion of ester-form bilirubin increased according to lowering blood pH, and reached maximum at pH 6.8. 5. As the results, most parts of bilirubin excreted into the urine was the ester-form bilirubin. The site of excretion of bilirubin was mainly tubulus and its rate of excretion might depend on affinity between serum protein and bilirubin. en-copyright= kn-copyright= en-aut-name=YamamotoTakehiko en-aut-sei=Yamamoto en-aut-mei=Takehiko kn-aut-name=山本武彦 kn-aut-sei=山本 kn-aut-mei=武彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=637 end-page=644 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of Irradiation on Lipid Peroxidation in SerumPart 1.

In addition, a study was made on the correlation between the peroxidation product and the change of fatty acids, and the following results were obtained. 1) The whole lipid content of serum: The whole lipid content was found to have increased about 2.6 times that before the irradiation by 24 post-irradiation hours, and even after the lapse of 48 hours such a tendency persisted. 2) Serum whole TBA level: By 24 post-irradiation hours the whole TBA level increased markedly up to about 6.5-fold that before the irradiation. 3) Lipid content of fraction: Except for cholesterol, every lipid fractions are found to have increased after irradiation. Especially marked is the increase of triglyceride. 4) TBA level of fractionated lipid: There is seen a marked increase of cholesterol ester, which proctically occupied entire serum TBA value. Next marked was the increase of phospholipid, and quantitatively it was classified that the increases seen in triglyceride and free fatty acids are not concerned with the rise in the free fatty acid content and TBA level. 5) Serum lipid contents and TBA level infasting: By taking the level of serum lipid 24 hours after the start of fasting as one, the serum lipid levels were studied at 48 and 72 hours after the start of fasting, and it was found that both serum lipid and TBA levels rose only very slightly. 6) Changes of fatty acids: The relative ratio of palmitic acid of the whole fatty acids increased after irradiation, and the ratio of linolic acid and linolenic acid was decreased by irradiation while by 48 hours the relative ratio of linolic acid was decreased to about 1/5 that before irradiation, and the relative ratio of linolenic acid was markedly decreased to about 1/35. en-copyright= kn-copyright= en-aut-name=HaisaYoshio en-aut-sei=Haisa en-aut-mei=Yoshio kn-aut-name=羽井佐芳雄 kn-aut-sei=羽井佐 kn-aut-mei=芳雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部放射線医学教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=615 end-page=635 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical Significance of Serum γ-Glutamyl Transpeptidase Activity in Hepatobiliary Diseases kn-title=肝・胆道疾患における血清γ-Glutamyl transpeptidase活性の臨床的意義 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serum γ-glutamyl transpeptidase (γ-GTP) activities in patients with various hepatobiliary diseases were studied to elucidate the clinical significance of the enzyme. In an early stage of acute hepatitis, an elevation of the enzyme activity was slight or moderate, and the alteration of the activity in the clinical course behaved in a parallel manner with that of serum GPT activity. Estimation of the γ-GTP activity in a convalescent stage of acute hepatitis was useful for predicting the prognosis of the disease. A marked elevation of serum γ-GTP activity was observed in icteric primary hepatoma, especially when the tumor was large and situated at the hilar portion or in the right lobe of the liver, and in secondary carcinoma, the activity higher than that in primary hepatoma was obtained, when the cancer metastasized to the porta hepatis or infiltrated into the liver along the bile ducts even though jaundice was not revealed. In biliary diseases, the level of serum γ-GTP had a close correlation with those of alkaline phosphatase and leucine aminopeptidase. en-copyright= kn-copyright= en-aut-name=NomaKeisuke en-aut-sei=Noma en-aut-mei=Keisuke kn-aut-name=野間啓輔 kn-aut-sei=野間 kn-aut-mei=啓輔 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=611 end-page=614 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on non-bilirubin fraction showing positive diazo-reaction in heterozygote Gunn rat bile kn-title=Gunn rat （Hetero）の胆汁中非bilirubin-diazo反応陽性分画 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Non-bilirubin fraction was extracted from the bile obtained from Wister strain rats and heterozygote Gunn rats, and separated by Ostrow(1)s method with minor modification. Azo-pigments was prepared with the non-bilirubin fraction after addition of Ehrlich(1)s diazo reagent. Significance of non-bilirubin fraction showing positive diazo reaction (NBAPF) was studied on the basis of the relation between the percentage of NBAPF to total bile azo pigments (proportion of NBAPF) and molar ratio of glucuronic acid to the ester-form bilirubin. The following results were obtained; 1) Averaged proportions of NBAPF were 0.94% in Wister strain rats and 2.50% in heterozygote Gunn rats, respectively. The latter proportion was higher than the former but not significant due to the wide variation of the measured values of the latter group. 2) Good correlation between the proportion of NBAPF and the molar ratio of glucuronic acid to the ester-form bilirubin was observed. 3) No significant correlation was observed between the bilirubin concentration in the bile and the molar ratio of glucuronic acid to the ester-form bilirubin or the proportion of NBAPF. 4) These results suggest when the conjugation of bilirubin and glucuronic acid in the liver was impaired, both the excretion of dipyrryl substance yielded from bilirubin and other conjugation mechanism increase compensatory. en-copyright= kn-copyright= en-aut-name=KondoTadasuke en-aut-sei=Kondo en-aut-mei=Tadasuke kn-aut-name=近藤忠亮 kn-aut-sei=近藤 kn-aut-mei=忠亮 aut-affil-num=1 ORCID= en-aut-name=HirohataMamoru en-aut-sei=Hirohata en-aut-mei=Mamoru kn-aut-name=広畑衛 kn-aut-sei=広畑 kn-aut-mei=衛 aut-affil-num=2 ORCID= en-aut-name=SeoKenji en-aut-sei=Seo en-aut-mei=Kenji kn-aut-name=瀬尾憲司 kn-aut-sei=瀬尾 kn-aut-mei=憲司 aut-affil-num=3 ORCID= en-aut-name=WatanabeYutaka en-aut-sei=Watanabe en-aut-mei=Yutaka kn-aut-name=渡部寛 kn-aut-sei=渡部 kn-aut-mei=寛 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=2 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=3 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=4 en-affil= kn-affil=岡山大学医学部第一内科教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=601 end-page=609 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=In-vitro Study of Cell-mediated Immunity in Collagen Diseases Part U: Macrophage migration inhibition test (MIT) and leucocyte migration inhition test (LMIT) in rheumatoid arthritis (RA) kn-title=In vitro assayを用いた膠原病における細胞性免疫の検索 第二編 RAにおけるMIT, LMIT en-subtitle= kn-subtitle= en-abstract= kn-abstract=The inflamed synovium of a patient with RA is intensively infiltrated with lymphocytes which often form follicles with aparent germinal centers. The synovial fluid contains aggregates of IgG and its complexes with rheumatoid factor. These evidences point out the immunological significance for the synovial inflammation and also suggest the need to determine whether cell-mediated immunity is concerned with the pathogenesis of RA. In the present study, an attempt has been made to determine whether heat-aggregated IgG and synovial crude extract have acted as antigns capable of causing cellular hypersensitivity in patients with RA. MIT and LMIT have been taken as in-vitro expression of cellular hypersensitivity. The value below the mean percent migration of normal subjects minus 2 SD was considered to be positive. MIT with heat-aggregated IgG was positive in 6 out of 14 patients with RA. Heat-aggregated IgG and synovial crude extract inhibited leucocyte migration in 4 out of 12 patients with RA. Indirect LMIT with heat-aggregated IgG was positive in 4 out of 14 patients with RA and with synovial crude extract in 5 out of 14 patients. None of normal subjects showed positive leucocyte migration inhibition to both antigens. There was no correlation between positive tests and titers of rheumatoid factor, duration, activity of the disease. The data presented above raise the possibility that cell-mediated immune mechanisms play a role in the pathogenesis of RA. en-copyright= kn-copyright= en-aut-name=YanoKeisuke en-aut-sei=Yano en-aut-mei=Keisuke kn-aut-name=矢野啓介 kn-aut-sei=矢野 kn-aut-mei=啓介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第三内科 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=587 end-page=599 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=In-vitro Study of Cell-mediated Immunity in Collagen Diseases Part T: Macrophage migration inhibition test (MIT) and leucocyte migration inhibition test (LMIT) in systemic lupus erythematosus (SLE) kn-title=In vitro assayを用いた膠原病における細胞性免疫の検索 第一編 SLEにおけるMIT, LMIT en-subtitle= kn-subtitle= en-abstract= kn-abstract=The appearance of circulating antibodies to nuclear components (e.g. DNA, Histone, Nucleoprotein) is characteristic of SLE and may have pathogenic importance. But, it is not evident why these autoantibodies are produced. Concerning these immunological abnormalities, most research has concentrated on the humoral immune responses made against nuclear antigens. The role of cell-mediated immunity to unclear antigens in SLE has not been investigated. Therefore, the evidence of cell-mediated immunity to native calf thymus DNA was determined by MIT and LMIT in patients with SLE and normal subjects. The mean percent migration of MIT in SLE and normal subjects was 79.8±24.1 and 101.4±15.3%, respectively. The percent migration below 70.8% was considered to be a positive test and 17 out of 42 patients with SLE had a positive test. In contrast, none of normal subjects did. These findings indicate that there is cellulay hypersensitivity to native DNA and peripheral lymphocytes of SLE patients produced a migration inhibitory factor (MIF) with responding to it. No correlation could be made between results of MIT and staining patterns of antinuclear factor (AMF), titers of anti-DNA antibody, serum complement levels and activity of the disease. The results of LMIT was differed from those of MIT. The mean percent migration of LMIT was not significantly different in SLE patients and normal subjects, and only a few cases in SLE exhibited a positive test. Considering the dissociation of these results in MIT and LMIT, the conclusion has been made that MIT is more useful in investigation the existence of cellular hypersensitivity. In addition, the role of T cells in the development of autoimmunity was discussed in accordance with the existence of cellular hypersensitivity to native DNA in SLE. en-copyright= kn-copyright= en-aut-name=YanoKeisuke en-aut-sei=Yano en-aut-mei=Keisuke kn-aut-name=矢野啓介 kn-aut-sei=矢野 kn-aut-mei=啓介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第三内科 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=575 end-page=585 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on bile pigments Part 2.

Following results about the nature of non bilirubin fraction positive for diazo reaction and its clinical significance was obtained. 1) The material obtained in the fraction was yellowish and soluble in water and showed positive diazo reaction. Its absorption maximum showed 545-555nm in water solution (pH 2.4) and unchanged by acidulation. 2) In thin layer chromatogram of this azo pigment of non bilirubin fraction, two to four spots appeared usually. This results suggested that it was not composed from one substance. The Rf values were different from those of already reported azo pigments in thin layer chromatogram and it was confirmed that the Rf value of one of these spots was changed by methylation. 3) Percentage of non bilirubin fraction in total bilirubin in bile of various liver and biliary tract diseases was significantly increased in comparison with that of control subjects. This ratio increased in the order of the group of constitutional jaundice, cirrhosis of the liver and chronic hepatitis respectively. 4) Significant correlations between percentage of non bilirubin fraction in total bilirubin and liver function tests (ZnTT, TTT, γ-globulin) were obtained. These findings suggested that non bilirubin fraction was increased in the case of hepatic parenchymal damage or the disturbance of the bilirubin conjugation enzyme. en-copyright= kn-copyright= en-aut-name=HirohataMamoru en-aut-sei=Hirohata en-aut-mei=Mamoru kn-aut-name=広畑衛 kn-aut-sei=広畑 kn-aut-mei=衛 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科学教室 END start-ver=1.4 cd-journal=joma no-vol=87 cd-vols= no-issue=7-8 article-no= start-page=563 end-page=573 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on bile pigments Part 1.

Bilirubin was extracted from the bile and separated with Billing's siliconized Kieselguhr column chromatography. Bilirubin-phosphate fraction showing positive phosphate ester reaction reported by Kondo, was fractionated with cellulose column chromatography as reported by Monobe, and finally its percentage to total direct bilirubin was calculated. Correlations between bilirubin-phosphate fraction and various liver function tests were studied and the following results were obtained. 1) Bilirubin-phosphate fraction was found to be 7.3% in cirrhosis of the liver, 5.5% in constitutional jaundice, 5.0% in acute hepatitis, 3.5% in chronic hepatitis, 2.2% in cholecystopathy and 2.1% in controls. Percentage of bilirubin-phosphate fraction was significantly higher in cirrhosis of the liver than in control, cholecystopathy and chronic hepatitis, and in acute hepatitis than in control and cholecystopathy. 2) There were good correlations among percentage of bilirubin-phosphate fraction, colloidal reaction (ZnTT, TTT) and serum γ- globulin fraction. 3) No significant correlations could be found among percentage of bilirubin-phosphate fraction, serum transaminase (GOT, GPT), cholesterol and alkaline phosphatase. 4) There was a good correlation between percentage of bilirubin-phosphate fraction and BSP retention at 45 minutes. 5) A significant negative correlation was obtained between percentage of bilirubin-phosphate fraction and K(ICG). en-copyright= kn-copyright= en-aut-name=HirohataMamoru en-aut-sei=Hirohata en-aut-mei=Mamoru kn-aut-name=広畑衛 kn-aut-sei=広畑 kn-aut-mei=衛 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=1055 end-page=1064 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the host immune response in cancer Part U.

Immune function, including total lymphocyte counts, T and B lymphocyte counts, in vitro lymphocyte blastogenesis by PHA and PPD and PHA skin reaction, were evealuated serially in reference to intensive cancer chemotherapy. The results obtained were as follows: 1) Although total lymphocyte counts, T and B lymphocytes counts, and in vitro blastgenic activity by PHA were significantly decreased immediately after COMP therapy, these parameters recovered to pretreatment level approximately within 3 to 4 weeks interval to next COMP therapy, there were no significant changes in PPD and PHA skin reaction following COMP therapy. 2) There was no relationship between pretreatment immune function and response to COMP therapy. 3) Recovery from impaired immune function was noted occasionally among the responders to COMP therapy. 4) A close relationship was noted between pretherapy response to PHA skin reaction, as well as pretherapy performance status, and survival of stage V lung cancer patients treated with COMP therapy. en-copyright= kn-copyright= en-aut-name=KanagawaOsami en-aut-sei=Kanagawa en-aut-mei=Osami kn-aut-name=金川修身 kn-aut-sei=金川 kn-aut-mei=修身 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=1041 end-page=1054 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the host immune response in cancer Part I.

When tumor bearing mice were injected their own tumor cells in foot pad, foot pad thickning was observed. Microscopic examination revealed that this thickning was not due to tumor growth but caused by polymorphonuclear and mononuclear cell infiltrations. This reaction was specific to their own tumor cells and was able to be transfered by spleen cells and peritoneal exudate cells. Immunopotentiators, when administered prior to tumor inoculation, these three agents had no effects on foot pad reaction, but when administered after tumor inoculation PS-K enhanced the foot pad reaction. Although cyclophosphamide had a significant suppressive effects on foot pad reaction, the reaction was restored by the concomitant use of these three immunopotentiators. This findings suggested that these immunopotentiators might restore the patient's immunity against one's own tumor when used concomitantly with cytotoxic agents in the management of cancer patient. On the other hand, concomitant use of carragheenan with OK-432 or Levamisole resulted in enhancing the suppressive effect cauced by carragheenan alone. en-copyright= kn-copyright= en-aut-name=KanagawaOsami en-aut-sei=Kanagawa en-aut-mei=Osami kn-aut-name=金川修身 kn-aut-sei=金川 kn-aut-mei=修身 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=1029 end-page=1039 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the cause of iron deficiency anemia Part 2. Induction of experimental anemia by excess iron excretion kn-title=鉄欠乏性貧血の成因に関する研究 第2編 鉄過剰排泄による実験的貧血 en-subtitle= kn-subtitle= en-abstract= kn-abstract=It was studied experimentally whether excess iron excretion can cause anemia in growing rats given desferrioxamine (DFO) intramusclarly. In the group injected with 150 mg/kg DFO daily for five weeks, urinary iron excretion started to increase after one week, and then hemoglobin concentration decreased after two weeks of treatment. The difference in hemoglobin concentration between the experimental and control groups was significant when treatment was continued for four weeks, although no significant differences were observed in erythrocyte counts. Thus, hypochromic anemia was induced. However, DFO at this dose did not retard growth in rats. In the second step, iron metabolism was examined. The same dose of DFO was administered to another group of rats every day for the same period. Compared to the control group, serum iron levels were higher in the rats injected with DFO. On the contrary, there were no differences in the total iron binding capacity. Liver nonhemin iron content in DFO-injected rats showed a marked decrease, which was nearly half of that in the controls. Diminution of bone marrow sideroblasts and bone marrow stainable iron was found at almost every case treated with DFO. It was demonstrated in these experiments that excess iron excretion induced by DFO resulted in iron deficiency anemia. These results give an experimental support to the concept of "Iron-losing anemia", anemia caused by the loss of nonhemin iron. en-copyright= kn-copyright= en-aut-name=MiyataAkira en-aut-sei=Miyata en-aut-mei=Akira kn-aut-name=宮田明 kn-aut-sei=宮田 kn-aut-mei=明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=1015 end-page=1027 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the cause of iron deficiency anemia Part 1.

In this test, urinary iron excretion and serum iron levels were measured after intravenous administration of 10mg of saccharated iron oxide. Thirty men and 68 women were studied with this test. They were divided into four groups: 62 cases of idiopathic hypochromic anemia, 9 cases of anemia due to blood loss, 4 cases of postgastrectomy anemia and 11 healthy controls. Patient with idiopathic hypochromic anemia were divided into two subgroups according to the rate of recurrence. Cases that developed anemia at least two times despite the standarized treatment with iron preparations constituted a group difficult to control, while the other group was easy to control. In the difficult-to-control group, urinary iron excretion showed a significant increase until two hours after injection when compared with that of the other four groups. An "Iron excretion index" was calculated to estimate the tendency for urinary iron loss more clearly. The difficult-to-control group of idiopathic hypochromic anemia had significantly higher excretion indices than other groups, which frequently exceeded 1.0. These results suggest that excess iron excretion may be one of the causes of idiopathic hypochromic anemia. This type of anemia may be designated "Iron-losing anemia". And "Iron excretion test" would be useful to detect this condition easily. en-copyright= kn-copyright= en-aut-name=MiyataAkira en-aut-sei=Miyata en-aut-mei=Akira kn-aut-name=宮田明 kn-aut-sei=宮田 kn-aut-mei=明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=999 end-page=1013 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Purification and properties of a high molecular weight acid soluble nuclear protein from mouse ascites sarcoma cells kn-title=マウス腹水肉腫細胞核からの高分子量酸可溶性蛋白質の精製とその性質 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A high molecular weight acid soluble nuclear protein (HAN-1) was isolated in a electrophoretically homogeneous state from mouse ascites sarcoma cells (SR-C3H cells) by the exclusion chromatography in Sephacryl S-200 and the DEAE-Sephadex chromatography of the nuclear 0.2M H(2)SO(4) extract.

The clarified facts and the conclusions thereby were as follows: 1) At the shipbuilding plant, lagging workers and carpenters were engaged in asbestos-handling works. The environmental airs around the lagging workers and carpenters were measured and proved to have 4 and 55.4 fibres/c? of asbestos in maximum respectively. Carpenters were engaged in works cutting several kinds of noninflammable board and sound proofing board. For the works, large quantity of asbestos dust was generated. It was observed that the lack of experience and knowledge for asbestos-works had delayed the measures to protect the hazards. The need of the establishment of the countermeasures against general dust hazards as well as asbestos dust hazards must be urgently recognized. 2) The asbestos-handling works might influence on other works which were carried out simultaneously in the same new ship under construction. The prevention of asbestos hazards for other workers must be considered. 3) Chest X-ray examination explored that 35.7% of lagging workers and 31.0% of carpenters had pneumoconiosis. Asbestos bodies were found with high frequency in both groups. The facts supported that they had suffered from the exposure of asbestos substantially. Between the two groups, differences of X-ray findings were observed; irregular small opacities in lagging workers and irregular small opacities as well as compound small opacities in carpenters. They were thought to be due to the differences of kinds of dust inhaled. 4) The countermeasures against the cutting procedure of asbestos cloth and pipe covering in the case of lagging workers, and the dust generated in high density by electric rotary saw in the case of carpenters are the urgent need to be established. en-copyright= kn-copyright= en-aut-name=MimuraKeiji en-aut-sei=Mimura en-aut-mei=Keiji kn-aut-name=三村啓爾 kn-aut-sei=三村 kn-aut-mei=啓爾 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部衛生学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=969 end-page=979 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Aging and sensitivity of rat granulation tissue and thymus to glucocorticoids kn-title=加令と肉芽組織ならびに胸腺の糖質コルチコイドに対する感受性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Granulomas were induced in rats of both sexes at different weeks of age by subcutaneous implantation of formalin-soaked filter-paper disks. The sensitivity changes with aging to the antigranuloma and thymolytic actions of prednisolone acetate were studied by measuring the dry-defatted weight of granulomas and the wet weight of thymus. The prednisolone acetate effects on these tissues were also investigated by electron microscopy. In male rats, the amount of granulation tissue increased from 6 to 12 weeks of age; but no difference in granuloma weight was evident between the 12- and 20-week-old groups. In females, the granuloma weight also increased form 6 to 8 weeks. However, heavier granulomas were found in males than in females. In both sexes, the 20-week-old group showed lower sensitivity to the antigranuloma and thymolytic actions of prednisolone acetate than the 6- and 8-week-old groups. In the 6-, 8-and 20-week-old groups of both sexes, marked differences were not found between the antigranuloma potency and thymolytic potency of prednisolone acetate. The prednisolone acetate dose required to produce appreciable electron microscopic changes were about the same in granulation tissue and thymus. The present results show that rat granulation tissue and thymus have similar degrees of sensitivity to glucocorticoids and that the sensitivity of these tissues is lowered with aging. en-copyright= kn-copyright= en-aut-name=FujiwaraRyoichi en-aut-sei=Fujiwara en-aut-mei=Ryoichi kn-aut-name=藤原良一 kn-aut-sei=藤原 kn-aut-mei=良一 aut-affil-num=1 ORCID= en-aut-name=SaekiKiyomi en-aut-sei=Saeki en-aut-mei=Kiyomi kn-aut-name=佐伯清美 kn-aut-sei=佐伯 kn-aut-mei=清美 aut-affil-num=2 ORCID= en-aut-name=TomitaSeiichiro en-aut-sei=Tomita en-aut-mei=Seiichiro kn-aut-name=富田精一郎 kn-aut-sei=富田 kn-aut-mei=精一郎 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部薬理学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部薬理学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部寄生虫学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=949 end-page=968 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Electron microscopic study of the histamine effect on granulation tissue growth kn-title=肉芽組織の増殖に及ぼすhistamineの効果に関する電顕形態学的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Daily administration of histamine at 0.5 mg/kg x 2, s.c., and prednisolone at 5 mg/kg, p.o., significantly inhibited growth in granulomas induced by subcutaneous implantation of formalin-soaked filter-paper disks as shown by the lower dry-defatted granuloma weight compared with control group. Electron microscopic observations showed that both histamine and prednisolone decreased the cell density of granulation tissue. In granulomas of rats treated with prednisolone, the development of fibroblast rough endoplasmic reticulum was inhibited, and many lipid droplets were found in these cells. The formation of collagen fibers was significantly inhibited in such granulation tissues. Fibroblasts in granulation tissues from histamine-treated rats showed greater development of rough endoplasmic reticulum and had more mitochondria and dense bodies than fibroblasts of control granulation tissues. The collagen fiber formation in granulation tissue seemed more active in histamine-treated animals than in control animals. In cell counts under the electron microscope, in the period from 3 to 7 days after implantation of filter-paper disks, the percentage of macrophages in granulation tissue decreased to the total number of macrophages, fibroblasts and cells with intermediate characteristics, whereas the count of fibroblasts increased. These time-dependent changes in percentages of macrophages and fibroblasts were accelerated by histamine. These results suggest that histamine mainly through inhibition of cell proliferation, especially of fibroblasts, and acceleration of the differentiation of these fibroblasts inhibits the formation of granulomas. en-copyright= kn-copyright= en-aut-name=FujiwaraRyoichi en-aut-sei=Fujiwara en-aut-mei=Ryoichi kn-aut-name=藤原良一 kn-aut-sei=藤原 kn-aut-mei=良一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部薬理学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=915 end-page=948 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Microcirculation of gastric ulcer A scanning electron microscopic study of vascular casts kn-title=血管鋳型法による正常および胃潰瘍の血管構築の走査電子顕微鏡的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Under a scanning electron microscope, the microcirculation of normal and pathological stomachs was observed by a corrosion casting technique. This improved approach has been in the microvascular pattern of gastric ulcers to clarify its non-healing and recurring tendency. In the case of a normal rat, arteries, upon penetrating the serosa and immediately branched into capillaries at the base of the gastric gland. These mucosal capillaries run upward in more or less straight lines from the submucosal plexus toward the surface and continued to the vascular net on the mucosal surface. Part of the vascular net continued into a descending collecting venule which ran downward in a straight line, increasing in diameter and continuing into a collecting vein. An arteriovenous anastomotic channel was found between the artery and vein of the submucosal plexus. Although the microvascular pattern of the normal human stomach was little more complicated than that of the rat, its basic pattern was the much same. In the case of an experimental chronic gastric ulcer (acetic acid ulcer by Okabe), there are two unusual vascular structures, i.e., increased vessels and radiating vessels; histologically they represent zone of granulation and scar, these vessels are not observed horizontal anastomoses of each other. In particular, there are horizontal anastomose in the least between this vessel in scar and the vessel of the adjacent area. By the effects of the vagotomy and the drug (Gefarnate), this horizontal anastomose not change for the better during observation. In the case of a human chronic gastric ulcer, this particular pattern on the microcirculation was the much same. As a result of these observation, this particular pattern on the microcirculation can readily assumed that healing of deep ulcer is difficult. If it should heal, there appear weak points of blood supply, for the regenerated epithelium is supplied only by the poor scar vessels. en-copyright= kn-copyright= en-aut-name=TakaoMasahiko en-aut-sei=Takao en-aut-mei=Masahiko kn-aut-name=高尾正彦 kn-aut-sei=高尾 kn-aut-mei=正彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1外科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=901 end-page=914 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Spontaneous malignant transformation of rat liver cells in long-term culture Part 2.

Three cases of CLL were T-cell type, e.g. SRBC rosette forming cells, and 3 cases of ALL were null cell type. The surface structure of leukemic cells in CLL was smooth type, or intermediate type, although it was smooth type or a part of the cells had many blebs and ridge-like processes in ALL. A part of peripheral lymphocytes in patients with SLE showed abnormal, irregular shape and had blebs, ridge-like processes. Such abnormal cells were frequently detected in the cases which T-cells were decreased. Leukemic cells in one case of leukemic reticuloendotheliosis (acute type) had very short ridge-like projections. Monocytic leukimic cells had the similar surface structure as normal peripheral monocytes which had ruffled membranes, but their processes were larger or broader. Plasmoid cells in patient with IgG(k) type multiple myeloma had villous surface structure, however that in IgD (λ) type were bullous. This findings suggested that the surface structure was different among immunoglobulin classes which were produced by myeloma cells. en-copyright= kn-copyright= en-aut-name=NishiyaKoji en-aut-sei=Nishiya en-aut-mei=Koji kn-aut-name=西谷皓次 kn-aut-sei=西谷 kn-aut-mei=皓次 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第三内科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=869 end-page=885 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Scanning electron microscopic observation of the cells related to immunological phenomena Part I. normal cells kn-title=免疫担当細胞の走査型電子顕微鏡像 第一編 正常細胞 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Human lymphocytes, granulocytes and monocytes were purified from normal human peripheral blood, using Ficoll-Conray gradient sedimentation and glass adherent activity of monocytes. The characteristics of surface structure among them were easily shown by SEM observation, e.g. monocytes had ruffled, granulocytes had ridge-like and lymphocytes had finger-like projections on their surface. Most of purified SRBC-RFL (T-cells) had smooth surface structure. However, the approximate ten percentage of them showed the villous one. A MRBC-RFL which belonged to surface immunoglobulin bearing cells (B-cells), showed the smooth one. It was concluded from the results that it was difficult to judge only from their surface characteristics whether the lymphocytes were T-or B-cells. Erythrophagocytosis by human monocytes bia Fc-receptor consisted of attachment, engulfment and cytolysis. SEM observation clarified the surface morphological changes of monocytes and erythrocytes in each stage. This phenomenon indicated that erythrophagocytosis might play a role in hemolysis of patient with autoimmune hemolytic anemia. en-copyright= kn-copyright= en-aut-name=NishiyaKoji en-aut-sei=Nishiya en-aut-mei=Koji kn-aut-name=西谷皓次 kn-aut-sei=西谷 kn-aut-mei=皓次 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第三内科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=863 end-page=868 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Bacteriuria in the community by testape kn-title=試験紙法による集団の細菌尿のスクリーニング成績について en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the course of the screening examination of the adult diseases, 4959 inhabitants (both sex with age from 20 to 89 years) of communities in the south of Okayama Prefecture were examined bacteriuria with the nitrite testape (N-multisticks, Ames Co.) without cleaning pudenda from April to December, 1977, and the following results were obtained. 1) The rate of bacteriuria was 1.4% of the examinee, but the rate of bacteriuria of female (1.6% ) was 3.2 times higher than that of male (0.5% ). The rate by age of bacteriuria of male had single peak in his fifties, but that of female had bottom in her thirties, and after this age the rate rose with increasing age. 2) The cystitis of the urinary bladder or the kidney disease were the commonest disease among the past history of the cases, especially in female, with bacteriuria. About 1/4 of the cases with bacteriuria had complaints, and the pollakisuria was the commonest complaints (23.5% ). 3) The cases of bacteriuria complicated with albuminuria or occult blood were superior to that non-complicated in number, and the cases of glykosuria had bacteriuria to a high rate. 4) In 59.5% of the positive cases of the N-multisticks pyuria was observed microscopically in urinary sediments. en-copyright= kn-copyright= en-aut-name=OkamotoTadashi en-aut-sei=Okamoto en-aut-mei=Tadashi kn-aut-name=岡本正 kn-aut-sei=岡本 kn-aut-mei=正 aut-affil-num=1 ORCID= en-aut-name=SunamiShigeo en-aut-sei=Sunami en-aut-mei=Shigeo kn-aut-name=角南重夫 kn-aut-sei=角南 kn-aut-mei=重夫 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=川崎医科大学 affil-num=2 en-affil= kn-affil=川崎医科大学 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=851 end-page=861 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=CSF monoamine metabolites and cyclic nucleotides in chronic schizophrenic patients with tardive dyskinesia or drug-induced tremor kn-title=遅発性ジスキネジア及び薬剤性振戦を伴う患者の髄液アミン代謝物質と環状ヌクレオチド en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lumbar CSF HVA, MHPG, 5HIAA, cAMP and cGMP were measured in 12 chronic schizophrenics with tardive dyskinesia (TD) before and 3 weeks after sodium valproate (VPA) or cyproheptadine treatment. The amount of medication was kept constant throughout the study. Three of the 7 patients treated with VPA and 1 of the 5 with cyproheptadine showed improvement. HVA levels significantly decreased and cAMP and cGMP levels significantly increased. MHPG levels increased significantly during the treatment with VPA but declined during cyproheptadine treatment. There were no significant correlations between the degree of improvement in TD and the changes of amine metabolites or cyclic nucleotides. None of the pre-treatment values for CSF amine metabolites or cyclic nucleotides were different from those of 15 chronic schizophrenics without TD as controls. Decrease in HVA and increase in cGMP during the treatment might indicate the normalization of dopaminergic-cholinergic imbalance in the brain. Furthermore, amine metabolites and cyclic nucleotides were measured in 5 chronic schizophrenics with parkinsonian tremor. Low HVA and 5HIAA levels and high cAMP levels were observed in tremor group. However, only 5HIAA levels in tremor group were significantly lower than those in age-matched control group. It is suggested that neuroleptic-induced tremor may be attributed to serotonergic dysfunction in the brain. en-copyright= kn-copyright= en-aut-name=NagaoTakuo en-aut-sei=Nagao en-aut-mei=Takuo kn-aut-name=長尾卓夫 kn-aut-sei=長尾 kn-aut-mei=卓夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=841 end-page=849 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the cornin extracted from liver 2.

Crude rat liver microsomal cornin (RLMC) inhibits the growth of L-929 cells. MF1 is purified about 4 fold from RLMC by gel filtration through Sephadex G-50 column. 2. The concentration of MFI that inhibits the growth of L cells to 50% is 270 μg/ml and this specific activity is the highest of the cornin fractions reported up to date. 3. The content of acidic amino acids is more than 23% but that of histidine and sulfurcontaining amino acids is very low in MFl. 4. MFl shows the maximum ultraviolet absorption at 276nm and its main substance is a kind of protein, and its inhibitory effect on the cell growth diminishes by protease treatment. 5. MFl is a single peak both by polyacrylamide gel electrophoresis and by thin layer gel filtration and the molecular weight is calculated about 26,000. 6. MFl is separated in two bands by SDS-polyacrilamide gel electrophoresis and the molecular weight is estimated to be 11,000 and 15,000 respectively. en-copyright= kn-copyright= en-aut-name=DoiAkitaka en-aut-sei=Doi en-aut-mei=Akitaka kn-aut-name=土井昭孚 kn-aut-sei=土井 kn-aut-mei=昭孚 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一生理学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=819 end-page=840 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study of serum leucine aminopeptidase in lung cancer with particular reference to its isozyme fraction kn-title=肺癌患者における血清ロイシンアミノペプチダーゼに関する研究―特にアイソザイムと病態との関連について― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Leucine aminopeptidase (LAP) activity and its isozyme fraction were assayed in the serum of 34 cases of lung cancer, and were compared with those in the 34 cases of stomach cancer, 12 of breast cancer and 10 of various kinds of nonneoplastic lung disease as well as those of 25 healthy subjects. The cases with those having any abnormality in the result of hepatorenal function tests were excluded from this study. The activity of LAP was remarkably high in the lung cancer and 90% of the patients who showed abnormally high level of the activity was proved to be the lung cancer patient. The ratio of Y fraction in the isozyme of lung cancer was also significantly higher than that in any other group and this was demonstrated in 96% of the cases. Although there was no significant difference in the total activity of LAP among the stages of lung cancer, elevation of the ratio of Y fraction in isozyme was significant in accordance with the stage. This was fact even in the range of the tumor size. As to lymphnode metastasis of lung cancer, increase in both the ratio and activity of the Y fraction was observed in association with the progress of extent of the metastasis, and there was a significant difference in the values between those having metastasis within and beyond the mediastinum. It was demonstrated that the total activity of LAP and the ratio and activity of its Y fraction were higher even in the cases with stomach or breast cancer, but it was observed in the advanced stage in contrast with the lung cancer. Furthermore, the elevation of the ratio was consistently lower than that in the lung cancer. On the basis of the results mentioned above, it would be reasonable to signify a clinical value of assaying the Y fraction of LAP isozyme on the diagnosis and the treatment of lung cancer. en-copyright= kn-copyright= en-aut-name=OkadaKoji en-aut-sei=Okada en-aut-mei=Koji kn-aut-name=岡田幸司 kn-aut-sei=岡田 kn-aut-mei=幸司 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2外科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=795 end-page=818 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Serum human prolactin in patient with breast cancer kn-title=乳癌患者における血漿Prolactinの分泌動態に関する臨床的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endocrinological effects of prolactin on human breast cancer have not been documented.

Then, blood samples were taken in series after an injection of 500μg of TRH for stimulation. Patients studied were 61, including 57 with primary breast cancer, 4 with recurrent breast cancer. Control group consisted of 10 healthy women. Results obtained were as follows: 1) Basal level of prolactin was higher in 22 out of 61 patients (36%), compared with that of controls, and there was no statistically significant difference in the incidence in the patient whose basal level was higher than the upper limit of the control, between the each stage as well as between the pre- and postmenopausal group. 2) All patients responded to TRH stimulation and, in approximately 90% of the patient, the prolactin level reached to peak in a period of 15 to 30 minutes after the stimulation, regardless of the clinical stage and nearly one half of the patient except in stage I showed an excessive response. However, the return to the basal level was apparently retarded and about 30% of the patients showed higher level even at 60 and 90 minutes after the TRH stimulation. 3) There was no stage difference in incidence in patients whose levels 15 and 30 minutes after the stimulation were significantly elevated. However, the incidence in patient whose levels were higher that of the upper limit of controls was higher in patients belonged to stage U and V, compared with that in stage T. 4) No significant correlation existed between lymph node involvement and incidence of patients with high prolactin level in each stage groups. However, significant increase was present in the 15-minute and 30-minute levels of prolactin in patients with lymph node metastases, though there was no significant difference in accordance with extension of the metastasis. 5) In histological classification, scirrhus type showed higher basal levels as well as the levels after the stimulation, compared with those of papillotubular and medullotubular types. en-copyright= kn-copyright= en-aut-name=ItagakiFumio en-aut-sei=Itagaki en-aut-mei=Fumio kn-aut-name=板垣文夫 kn-aut-sei=板垣 kn-aut-mei=文夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=785 end-page=793 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Homogeneity of erythrocyte catalase and its stability to SDS and to LIS in acatalasemia and hypocatalasemia mice kn-title=アカタラセミア,ヒポカタラセミアマウスの赤血球カタラーゼの均一性およびSDS,LISに対する安定性について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Behavior of hemoglobin in the erythrocytes to the addition of H(2)O(2) in saline was examined to be confirmed the equal distribution of catalase in erythrocyte population from acatalasemic heterozygote mouse (Cs(a)Cs(b)) which showed the half of normal (Cs(a)Cs(a)) catalase activity. When H(2)O(2) was added in the suspension mixed erythrocytes with Cs(a)Cs(a) and acatalasemia (Cs(b)Cs(b)), the color changed immediately from red to brownish red with emitting a little buble of O(2). One population of erythrocyte lacking catalase activity should be caused the methemoglobin formation. In fact, rapid spectrophotometric scanning proved that the wave length of maximum absorbance were 500nm and 630nm. When H(2)O(2) was added in the erythrocyte suspension from Cs(a)Cs(b), the color unchanged, remained red, with emitting bubles of O(2). This result was the same as in the erythrocyte suspension from Cs(a)Cs(a). Data indicated that erythrocyte from heterozygote (Cs(a)Cs(b)) is consist of one population and is not two populations of Cs(a)Cs(a) and Cs(b)Cs(b). The nature of blood catalase by stability to the surfactant (SDS and LIS) was compared among normal (Cs(a)Cs(a)), acatalasemic homozygote and heterozygote (Cs(b)Cs(b) and Cs(a)Cs(b)), and hypocatalasemic homozygote and heterozygote (Cs(c)Cs(c) and Cs(a)Cs(c)) mice. In both respects of SDS and LIS stability, Cs(a)Cs(a) was most stable and two heterozygotes (Cs(a)Cs(b) and Cs(a)Cs(c)) were less stable than Cs(a)Cs(a). Cs(c)Cs(c) and Cs(b)Cs(b), namely Cs(b)Cs(b) were of least stability to SDS and to LIS. It was demonstrated that blood catalase molecule of acatalasemic and hypocatalasemic heterozygote (Cs(a)Cs(b) and Cs(a)Cs(c)) differs from that of both parents (Cs(a)(Cs(a), Cs(b)Cs(b) and Cs(a)Cs(c)). It was concluded that 5 sorts of blood catalase were different each other and consist of a single molecular species and suggested that since catalase was a tetramer, the combination of subunits was different each other. en-copyright= kn-copyright= en-aut-name=MizugakiJunko en-aut-sei=Mizugaki en-aut-mei=Junko kn-aut-name=水垣順子 kn-aut-sei=水垣 kn-aut-mei=順子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=7-8 article-no= start-page=765 end-page=783 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=197808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Influence of differential hypothermia on the metabolism of the Vx2 tumors transplanted in rabbits kn-title=家兎Vx2移植腫瘍の代謝におよぼすDifferential Hypothermia処置の影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=As a non-surgical treatment of malignant tumors, it has been experimentally confirmed that the differential hypothermia (D.H.), to keep the tumor normothermic locally under total body hypothermia, showed therapeutic effect on the tumor which was intensified by combination with antitumor agents. The application of D.H. to the treatment of malignant brain tumors in human beings and its mechanism against tumor have been discussed in the previous paper. In order to study the metabolic effect of D.H. on the tumor tissue, the present study was performed by using rabbit Vx2 tumor and applying D.H. for 10hours. The concentrations of major metabolites of the glycolytic pathway (glucose, G-6-P, F-6-P, FDP DAP, pyruvate, lactate) and high energy phosphate bonds (ATP, ADP, AMP, P-creatine) were measured by enzymatic techniques before, during and after the D.H. treatment. 1) The G-6-P concentration in D.H.-treated tumors showed an elevation as compared with that in control. Its concentration rose to 0.251 ± 0.044 mol/g immediately after the D.H. treatment and to 0.233 + 0.030 mol/g at 36th hour later. 2) Lactate concentration in D.H.-treated tumors also showed an elevation. Its concentration at 6th hour following the D.H. treatment was 18.6 ± 1.0 mol/g at 36th hour it was 19.0 ± 1.8 mol/g. Lactate/pyruvate ratio also elevated. 3) ATP concentration in D.H.-treated tumors decreased. Its concentration at 6th hour during the D.H. treatment was 0.708 ± 0.108 mol/g and at 36th hour it was 0.428 ± 0.090 mol/g. D.H.-treated tumors revealed a decrease of energy charge potentials. These experimental results are considered to show a metabolic mechanism of the antitumor effect of the D.H. treatment and seem to be compatible with the morphological evidence of tumor disappearance reported in the previous paper. en-copyright= kn-copyright= en-aut-name=KatagiRyosuke en-aut-sei=Katagi en-aut-mei=Ryosuke kn-aut-name=片木良典 kn-aut-sei=片木 kn-aut-mei=良典 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学脳神経外科学教室 END start-ver=1.4 cd-journal=joma no-vol=90 cd-vols= no-issue=3-4 article-no= start-page=479 end-page=496 dt-received= dt-revised= dt-accepted= dt-pub-year=1978 dt-pub=19780430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Optimal flow rate and studies in oxygen consumption during hemodilutional extracorporeal circulation kn-title=常温希釈体外循環における適正潅流量の検討:とくに酸素消費量の面より en-subtitle= kn-subtitle= en-abstract=Serial oxygen uptake determination were done in 39 patients and 24 mongrel dogs during 20% hemodilutional cardiopulmonary bypass at normothermia. In patients, the time of the bypass ranged from 37 to 161 minutes. In dogs, the bypass time was standardized at 120 minutes. In patients, average of the mean perfusion index was 2.03 l/M(2)/min in the group I (BSA≧1.2M(2),n=13), 2.47 l/M(2)/min in the group U (0.8≦BSA<1.2M(2),n=6) and 2.72 l/M(2)/min in the group V (BSA<0.8M(2),n=20). During total perfusion, the average of the mean arterial blood pressure was 75.7mmHg in group I, 53.6mmHg in group U, and 44.1mmHg in group V. The average of the mean oxygen saturation during perfusion were 60.5%, 64.2%, 56.7% and the average of the O(2) consumption were 72.5ml/M(2)/min, 94.7ml/M(2)/min and 112.6ml/M(2)/min respectively. O(2) consumption (during perfusion)/O(2) consumption (predicted) ranged 0.22 to 0.96 in all patients and 0.52, 0.62, 0.63 respectively. The average of the O(2) extraction rate during perfusion were 32.9% , 42.8% and 36.0% respectively. The average of hematocrit during perfusion was 24.4% in patients and 23.5% in dogs. In dogs, classified into 5 groups, group A perfused at rate 25ml/Kg/min had an average mean arterial blood pressure of 20.6mmHg, group B perfused at rate 50ml/Kg/min had 38.3mmHg, group C perfused at rate 75ml/Kg/min had 58.7mmHg, group D at rate 100ml/Kg/min had 67.7mmHg, group E at rate 125ml/Kg/min had 58.4mmHg. The average of the O(2) consumption were 1.66ml/Kg/min (group A), 2.87ml/Kg/min (group B), 4.10ml/Kg/min (group C), 3.62ml/Kg/min (group D), 5.91ml/Kg/min (group. E). 1) Mean arterial blood pressure varied directly with flow rate in dogs, but not in patients. During perfusion mean arterial blood pressure was maintained at a lower level and mean central venous pressure at a higher level than at pre-perfusion value. 2) There is a linear relationship between flow rate and oxygen consumption both in patients and dogs. Oxygen consumption during perfusion were considerably lower than normal oxygen consumption. 3) Venous oxygen saturation during perfusion was lower than pre-perfusion value. There is a linear relationship between flow rate and venous oxygen saturation in dogs, but not in patients. 4) In patients, relationship between perfusion index and O(2) consumption indicates that the perfusion index over than 2.7 l/M(2)/min will be desirable, and in dogs splanchnic pooling during perfusion suggested the flow rate 75-100ml/Kg/min will be desirable. kn-abstract=19世紀から多数の研究者により報告された体外での臓器潅流の研究は,1937年Gibbon(1))の酸素付加装置による猫の潅流実験ののちに,さらに進展の度を早め,臨床的には,1951年Dennisら(2))が心房中隔欠損症の手術に試み,ついで1953年Gibbonが本症の手術に成功して以来,直視下心臓手術は人工心肺装置ならびに体外循環手技などの改良により広くおこなわれるようになった.一方,体外循環の副作用として,血清肝炎(3)),赤血球のsludgingやaggregation(4)),blood pooling(5)6))や同種血症候群(7)8))が問題となり,また装置充填に多量の新鮮血を要することも欠点であった.当時,生理学的研究では臓器潅流に電解質液を使用していたこと,Gollanら(9))が低体温下では赤血球の無い液体でも溶存酸素のみで組織は酸素を摂取しうることを示したことにより,血液希釈体外循環が考えられた.1951年PanicoとNeptune(10))が生理的食塩水で充填したのに始まり,Longら(4))の低分子量デキストラン,Gooleyら(11)),Zuhdiら(12)),De WallとLilleheiら(13))の5% 糖液,そしてNevilleら(14))の乳酸加リンゲル液の使用により希釈体外循環が主流となった.しかし,血液希釈にともなう問題も生じた.すなわち血液希釈によるヘモグロビン濃度の低下した血液は,酸素運搬能力も低下し,この低下を代償するために潅流量を増加しなければならないと考えられる.従来は全血体外循環時に設定された潅流量を希釈体外循環にも用いられてきたが,その可否を酸素消費量および血行動態の面より検討した. en-copyright= kn-copyright= en-aut-name=SugimotoSeiki en-aut-sei=Sugimoto en-aut-mei=Seiki kn-aut-name=杉本誠起 kn-aut-sei=杉本 kn-aut-mei=誠起 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=1035 end-page=1047 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the distribution of lymphocyte subpopulations in human tissues Part 2.

Thymus-derived lymphocytes (T cells) and bone marrow-derived lymphocytes (B cells) were detected by rosette formation with sheep erythrocytes (E) or with sheep erythrocytes coated with antibody and complement (EAC) respectively. Almost all infiltrating lymphocytes in the salivery glands in patients with Sjogren's syndrome were identified as B cells and T cells were detected only along the ducts. In Hashimoto's thyroiditis, infiltrating lymphocytes with the lymph follicles in the thyroid gland were mostly B cells whereas T cells localized as surrounded the thyroid follicles. T cells would not be detected in the spleen sections obtained from the patients with hypoplastic anemia at all. The white pulp was constituted by B cells, and the mononuclear cells in the red pulp might be macrophages of which these cell surfaces had IgG-Fc receptors. The lymph follicles of the thymus in a patient with myasthenia gravis complicated with thymoma was demonstrated to be formed with B cells. Therefore, it could be concluded that B cells were predominant lymphocytes in the target organs, while T cells localized in situ developing the autoimmune reactions in various autoimmune diseases. en-copyright= kn-copyright= en-aut-name=KoriyamaKenji en-aut-sei=Koriyama en-aut-mei=Kenji kn-aut-name=郡山健治 kn-aut-sei=郡山 kn-aut-mei=健治 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=1021 end-page=1033 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the distribution of lymphocyte subpopulations in human tissues Part 1.

Invariable and stable reaction was obtained in EAC rosettes of the tissue lymphocytes while E binding of them was rather unstable. E could be adhered in the thymus sections which were obtained from normal infants during open heart surgery, but EAC did not bind to them at all. It was confirmed that B-cells located mostly in the lymph follicles of the lymph nodes as well as the palatine tonsils and T-cells were present predominantly in the paracortical area and interfollicular region. B-cells in the germinal centers would generally have more activated C(3) receptors than those of the mantle zones. In addition, B-cells of the lymph follicles both in the lymph nodes and in the palatine tonsils could be also detected utilizing the membrane immunofluorescence technique. The proportion of T and B-cells distribution in the lymphoid tissue was well correlated with that obtained on free cell suspension technique.Therefore, it could be concluded that T and B lymphocytes were able to identify respectively even in tissue level. en-copyright= kn-copyright= en-aut-name=KoriyamaKenji en-aut-sei=Koriyama en-aut-mei=Kenji kn-aut-name=郡山健治 kn-aut-sei=郡山 kn-aut-mei=健治 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=995 end-page=1019 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effect of an atherogenic diet on the healing of small vessel anastomoses in the rat kn-title=粥状硬化食投与ラットにおける微小動脈吻合術の実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=198 male albino rats were used in this experiment. First, 42 rats were divided into 13 different dietary groups to test the effects of high fat and cholesterol in the diet on the level of serum cholesterol and the degree of atherogenesis. Then the effects of four different types of diet upon the healing of small vessel anastomoses were studied. Group one received a regular control diet (MF diet, Oriental KOBO Co. Ltd.), group two, A diet (regular diet with cholesterol 5 % , peanut oil 5% and sodium cholate 2%), group three, AP diet (A diet with pyridinolcarbamate 0.05%), group four, AT diet (A diet with thiouracil 0.3%). All percentages were calculated on a weight basis. Each group received the above diets for 13 weeks before anastomosis. Then, end to end anastomosis of the common carotid artery was performed using the operating microscope. Rats were sacrificed in groups of 2 to 6 from 24 hours to 20 weeks postoperatively. Vessel patency was determined and histological and histochemical changes were noted. Average values of the level of s-cholesterol at the time of sacrifice were 80 mg/dl in the normal group, 484 mg/dl in the A group, 342 mg/dl in the AP group and 661 mg/dl in the AT group and patency rates were 23/30 (77%), 16/36 (44%), 17/32 (53%) and 3/8 (38%) respectively. Histologically, diffuse degeneration of smooth muscle cells in the media and marked deposition of fat granules in the intima and media were observed in the hypercholesteremic rats of groups A and AT. In the AT group mural thrombi were often observed around the site of anastomosis with narrowing of the lumen. In rats fed atherogenic diets, healing of the anastomosis was significantly delayed requiring 6 to 8 weeks as determined by histological evidence and about 12 weeks by histochemical. Some degree of degeneration with fat granules was noted in the walls of the vessels at the sites where the vascular clamps had been applied. Histochemical examination of anastomosed vessels from rats fed atherogenic diets A and AT showed markedly lower activities of LDH, G-6-PDH, SDH and Cy-O in the media and rather higher activities in the adventitia than in vessels from rats fed control diets. In all groups Ac-P activity increased in the adventitia following surgery then decreased gradually with the healing process and Al-P activity increased temporarily in granulation tissue. But the activity of this latter enzyme was found to be markedly decreased in the adventitia following surgery in the vessels of rats fed atherogenic diets and seemed to be correlated with the degree of medial necrosis. Patency rates were very low in rats fed the A, AP and AT diets as compared to those fed the control diet, there being a clear tendency for higher cholesterol levels to result in lower patency rates. It would appear that persistent hypercholesterolemia increases the risk of delayed occlusion at the anastomotic site caused by mural thrombi or atheromatous change. The rats in the AP group showed less prominent fat infiltration of the vessel wall and fewer mural thrombi than those of the A or AT groups. This work suggests that it would be advantageous to administer anti-coagulant and/or anti-atherogenic medication after vascular anastomosis and to maintain that therapy throughout the duration of the healing process. en-copyright= kn-copyright= en-aut-name=OharaSusumu en-aut-sei=Ohara en-aut-mei=Susumu kn-aut-name=小原進 kn-aut-sei=小原 kn-aut-mei=進 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室/徳島大学医学部脳神経外科学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=979 end-page=994 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Influence of differential hypothermia on transplanted hamster tumor II) A study of adenovirus type 12-induced T-antigen by immunofluorescence technique kn-title=Differential Hypothermiaのハムスター移植腫瘍におよぼす影響について II.

A high proportion of the tumor cells in the viable portions of the control tumors demonstrated specific fluorescent staining in three type. The most striking and consistent pattern was the presence of numerous fluorescent particles in the cytoplasm, which were granular and fleck-like shapes. A second type of fluorescence was fluorescent particles in the nucleus in addition to the cytoplasmic staining, and a third type was homogenous staining of nucleus. Immediately after DH treatment, the treated warmed tumor cells presented diminution of fluorescent staining, especially large numbers of granular fluorescences in the cytoplasms. Fleck-like and homogenous nuclear staining of the treated tumor cells scattered even at 10 and 15 hours after DH treatment, when treated tumor cells revealed necrobiotic findings in sections of HE and nucleic acid stain. But no fluorescence was observed at 20 and 24 hours after DH treatment, while not-treated hypothermic tumor cells demonstrated about same fluorescent staining as control tumor cells. It was suggested that cytoplasmic granular fluorescence diminished because DH treatment had an effect on thermo-sensitivity of T-antigen because DH treatment had an effect on thermo-sensitivity of T-antigen and/or inhibited T-antigen production, as well as loss of flecklike and hemogenous nuclear fluorescence was due to tumor cell necrosis by DH treatment. en-copyright= kn-copyright= en-aut-name=OhashiTakeo en-aut-sei=Ohashi en-aut-mei=Takeo kn-aut-name=大橋威雄 kn-aut-sei=大橋 kn-aut-mei=威雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学脳神経外科 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=955 end-page=977 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Influence of differential hypothermia on transplanted hamster tumor I) Effect of combination with shallow differential hypothermia and antimetabolites kn-title=Differential Hypothermiaのハムスター移植腫瘍におよぼす影響について I) Shallow Differential Hypothermiaと抗癌剤併用の効果について en-subtitle= kn-subtitle= en-abstract= kn-abstract=How to treat the malignant brain tumors has been one of the biggest problems in neurosurgery. It has been in the past, and it is still now. In addition to surgical removal of tumors, various non-surgical method have been tried for the treatment of malignant gliomas. The use of heating or of cooling are some of these methods. They have been tried for a long time. Already in 1866 Busch,W. observed disappearance of sarcoma in patients suffering from erysipelas. Westermark,N. in 1927 observed that rat transplanted tumors were caused to disappear by exposing to heating, while the adjacent normal tissues were not damaged under conditions lethal to the tumors. In 1960 Woodhall,B. heated tumors locally that were perfused with chemotherapy. Shingleton,W.W., in 1962, heated localized tumor tissue on the patients with cancer, combined with regional chemotherapy under generalized hypothermia. According to Popovic,V.P. et'al. in 1965, they were first to report that differential hypothermia, keeping tumors normothermic under total body hypothermia at a temperature of 4℃ during a period of 10 hours in experimental animals, induced disappearance of tumor without resuming their growth afterward. Popovic,V.P., et al. in 1966 carried out further experiments and observed that tumors of the animals disappeared also subsequent to cooling whole body to 4℃ for 1 hours with anti-tumor agent, as well as to cooling whole body to 30℃ for 24 hours without chemotherapy while the tumor kept at 37℃. However, in order to induce tumor disappearance the differential hypothermia has to last at least 4℃ for 1-10 hours, or 30℃ for 24 hours. Since deep hypothermia lasting several hours or shallow hypothermia for long time is not well tolerated in non-hibernators, namely human beings, present experiment has been performed in an attempt to simulate the conditions of clinical work as close as possible. For this purpose the bodies of 22 hamsters were mildly cooled to a temperature of 30℃, while cheek pouch transplanted tumors induced originally by adenovirus type 12 remained uncooled at 37℃ for 10 hours (Fig. 1, 2). The dose of 50mg/kg of 5-fluorouracil (5-FU) was administered intraperitoneally in single injection at the beginning of treatment of shallow differential hypothermia (Table 1, Fig. 2). This resulted in that within 7 days later 4 out of 22 tumors (20 % ) disappeared completely without resuming their growth afterward, and 12 out of 22 tumors (55 % ) regressed temporarily for a period of 10 days after treatment (Table 2, 3, Fig. 6-b, 8). When the same amount of 5-FU was administered into normothermic tumor-bearing animals or into hypothermic animals with hypothermic tumors, tumor size of the animals was not affected (Table 1, Fig. 5-a, 6-a). When shallow differential hypothermia was treated without any anti-tumor agent, neither normothermic tumor size nor hypothermic one of the animals was also affected (Table 1, Fig. 7-a). Histological findings were degeneration of tumor cells. Stainability of nucleolar RNA and nuclear DNA by means of methyl green-pyronine and Feulgen's methods was decreased already immediately after the shallow differential hypothermia treatment for 10 hours with 5-FU administration (Fig. 10-a). This was followed by, at 24 hours after the treatment, marked decreasing and loss of the stainability of nucleolar RNA and nuclear DNA as well as dismixture of chromatin and karyolysis of nuclei (Fig. 11-a, b). Scattered necrotic foci in the tumor tissue were obviously revealed 48 hours after the treatment. Tumor cells showed selectively these degenerative finding after treatment, while adjacent mucosal tissue of cheek pouch preserved their normal appearance almost wholly even 12 hours after the treatment (Fig. 10-c). Although inflammatory cell infiltration was observed 48 hours after the treatment, and followed by fibrocytic fibrosis in the submucosa thereafter, degenerative and necrotic change was never showed (Fig. 11-c, 12-a, b). The author discussed that 1) combination with differential hypothermia and anti-tumor agent was effective for experimental tumor, 2) selective destroying and normothermic state of the treatment should be useful for non-surgical therapy of malignant brain tumor, as well as 3) cellular sensitive function of differential hypothermia might be exsisted in nucleolus or nucleus of tumor cell. en-copyright= kn-copyright= en-aut-name=OhashiTakeo en-aut-sei=Ohashi en-aut-mei=Takeo kn-aut-name=大橋威雄 kn-aut-sei=大橋 kn-aut-mei=威雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学脳神経外科 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=949 end-page=953 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Pattern of immunoglobulin production in human lymphoblastoid cell lines kn-title=ヒトリンパ芽球様細胞株における免疫グロブリン産生の研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Membrane-associated (M-Ig) and cytoplasmic immunoglobulins (C-Ig) of 4 human lymphoblastoid cell lines and 3 clones isolated from one of them were examined by immunofluorescence test.

These arteries usually indicate pathological alterations. However, there are only a few reports on the healing processes of the anastomotic sites on the pathological arterial wall. In the present study, the histological and histochemical healing processes were investigated in an anastomotic site of normal and pathological arterial walls. Ninety-two normal rats and 96 Goldblatt rats were used. End-to-end anastomosis was performed on the left common carotid artery by microsurgical technique. The patency rates of anastomosis were 71.6 % in normal rats and 73.0 % in Goldblatt rats. Patent anastomosed arteries were observed at various post-operative periods, ranging from 24 hours to 12 weeks. For histological studies, hematoxylin-eosin and Van Giesen stainings were used. For histochemical studies, lactic dehydrogenase, glucose-6-phosphate dehydrogenase, succinic dehydrogenase, cytochrome oxydase, acid phosphatase and alkaline phosphatase were examined. Goldblatt rats were divided into two groups histologically. One group had a slight degeneration of the medial muscle, and the other group had a marked degeneration. This histological difference between the two groups was probably due to blood pressure. A histological examination revealed a healing stage at four weeks in the former group and the histochemical study showed healing at eight weeks in the former group. There was no significant difference on the healing process between the former group and normal rats. Goldblatt rats which showed marked degenerative changes of the medial muscle indicated a poor healing process with granulation in the outer regions of medial necrotic areas. At 12 weeks after anastomosis, histological examination still showed the prominent and widespread degenerative changes on the medial wall. The histochemical examinations of this group revealed few enzymatic activities in the media in areas adjacent to the anastomosis, although rather higher activities were observed in the adventitia in granulation areas adjacent to the anastomotic site. But alkaline phosphatase in the adventitia around the anastomotic site markedly decreased in activity. These decreased activities of the alkaline phosphatase were probably due to destruction of the vasa vasorum. These findings suggested that the cause of these prominent and widespread necrotic regions were due to the absence of circulating blood which was stopped by temporarily clipping and destruction of the vasa vasorum during the operation. But, normal and slight degenerative arterial walls did not indicate such prominent changes. It was suggested from these experimental study that the pathological arterial walls were easily injured in the ischemic condition during the operation. en-copyright= kn-copyright= en-aut-name=KageyamaToshiaki en-aut-sei=Kageyama en-aut-mei=Toshiaki kn-aut-name=景山敏明 kn-aut-sei=景山 kn-aut-mei=敏明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=913 end-page=927 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Dynamics of immunoglobulin E in cerebrospinal fluid in patients with various neurological diseases kn-title=各種神経系疾患における髄液免疫グロブリンE(IgE)動態 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immunoglobulin E was measured in concentrated cerebrospinal fluid (CSF) of controls and patients with various neurological disorders, including multiple sclerosis (MS). The radioimmunoaasay method was used for IgE and the single radial immunodiffusion method was used for other immunoglobulins. IgE in CSF was able to quantify in 86.4 % of 118 cases, and then, it is thought that there is quantitative IgE component in normal CSF. In controls (N=23) IgE contents ranged from 0.03 to 0.71 U/ml (M: 0.28 U/ml). IgE /100mg of total protein ratio in CSF ranged from 0.06 to 1.52 (M: 0.61 ). Then, it is suspected that normal value of IgE and IgE % is below 0.8 U/ml and 1.6. The CSF/serum ratio of IgE was about 0.1 % (0.08-0.12 % ). This value is larger than that of IgM, and smaller than that of IgA and suggests immunoglobulin permeability through the blood-brain-CSF barrier in reverse proportion to molecular weight. In pathological CSF, the increase of IgE was related to the increase of total protein, IgG, IgA and IgM levels but IgD. IgE level was increased in 19 of 84 cases (22.6 % ), especially high IgE level was seen in acute inflammatory diseases of central nervous system but in chronic disorders (for example dementia paralytica). Otherwise, polyradiculoneuritis and diseases with abnormality of CSF dynamics or brain atrophy, revealed the tendency of high IgE levels. In these disorders, the increase of IgE was parallel with total protein level, IgG and other immunoglobulins in most cases. The incidence of high IgE level in MS was 3 of 15 cases, but these increases of IgE were not corelated with abnormalities of other components in CSF and it was revealed the possibility of another pathophysiological process of IgE from IgG and other immunoglobulins in central nervous system. No relationship was present between the incidence of high CSF IgE level and various factors such as clinical stage, suspected lesion and severity of disturbance in MS. en-copyright= kn-copyright= en-aut-name=HayabaraToshiyuki en-aut-sei=Hayabara en-aut-mei=Toshiyuki kn-aut-name=早原敏之 kn-aut-sei=早原 kn-aut-mei=敏之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=903 end-page=911 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Optic neuritis : Studies on the epidemiology and the cerebrospinal fluid kn-title=視神経炎に関する神経学的観察―その疫学と髄液所見― en-subtitle= kn-subtitle= en-abstract=A follow-up study on 60 previously healthy patients with nomosymptomatic optic neuritis, retrobulbar neuritis and idiopathic optic atrophy is reported. 73 per cent of the cases with insidious onset and slow progression were male, and 70 per cent of the cases who was troubled repeatedly on vision were female. In many cases, fever, common cold and overwork had precipitated the optic neuritis. During the following period, 6 patients (15.4 % of cases with acute onset) suffered from the other neurological manifestations, and a half of them (7.7 % ) were diagnosed as multiple sclerosis. Patients, who was diagnosed as retrobulbar neuritis by ophthalmoscopic examination and, who was disturbed on vision bilaterally but unsimultaneously, and repeatedly have an affinity to multiple sclerosis. At the beginning of the disease, a mononuclear pleocytosis was noted in 20.5 per cent of the patients, and elevated total protein level in 35.9 per cent. Polyacrylamide gel disc electrophoresis of the lumbar CSF proteins from 39 patients and the measurement of IgG by single radial immunodiffusion from 10 patients, were carried out. It was characteristic that the electropherogram showed the increase of pre-albumin, fast α(2)-globulin + transferrin and γ-globulin, and the decrease of albumin. These results are similar to those in multiple sclerosis. IgG and IgG % is increased in cases of retrobulbar neuritis, although total protein content is high level in optic neuritis, and then, cases who was disturbed on vision unilaterally or bilaterally but unsimultaneously showed the high level of γ-globulin. Two of 3 patients who subsequently developed to multiple sclerosis, had the CSF findings indistinguishable from those in multiple sclerosis. In one patient, CSF protein level was normal but γ-globulin was increased selectively. Another patient showed the CSF findings with slightly elevated protein level, pleocytosis and increase of IgG and IgG % . kn-abstract=原因不明のmonosymptomaticな視神経炎および視神経萎縮の60例に対し,アンケートによる初診後の経過を調べ,初診時の髄液検査(39例)の結果と合せ検討した.1)症例の発症年令は,思春期前および初老期後は著しく少なく,性別は男女同数だが,経過別にみると,緩徐発症慢性経過は男性に,急激発症反復は女性に多い.2)発症誘因に,発熱・感冒・過労などがあり, MSに類似する.3)後に神経症状を呈したのは6例で,急激発症例の15.4 % にあたる.うちMSへ移行したのは3例7.7 % である.球後視神経炎のみに限ると, 18例中3例16.7 % である.4)眼底所見,罹患側,臨床経過などを分析すると,各々,球後視神経炎,両側非同時性,急激発症反復型がMSへの指向を示す.5) 髄液では,軽度細胞数増多,軽度蛋白量増加を示す.蛋白分画ではalbuminの減少,fast α(2)-globulin＋transferrinの増加,γ-globulinの増加の他pre-albuminの増加がうかがえた.6)眼底所見別にみると,蛋白量は視神経炎で高値であるのに対し,IgG,IgG % は球後視神経炎で増加を示す.罹患側別にみると,片側性および両側非同時性においてγ-globulinの増加を認む.経過別にみると反復型およびMS移行群で,蛋白量, γ-globulinの増加を示す,又MS移行の3例中2例で,初回発作時にMS的髄液所見(γ-globulinの選択的増加, IgG, IgG % の増加)を示した. en-copyright= kn-copyright= en-aut-name=HayabaraToshiyuki en-aut-sei=Hayabara en-aut-mei=Toshiyuki kn-aut-name=早原敏之 kn-aut-sei=早原 kn-aut-mei=敏之 aut-affil-num=1 ORCID= en-aut-name=YabukiSeiso en-aut-sei=Yabuki en-aut-mei=Seiso kn-aut-name=矢吹聖三 kn-aut-sei=矢吹 kn-aut-mei=聖三 aut-affil-num=2 ORCID= en-aut-name=FukuiHideaki en-aut-sei=Fukui en-aut-mei=Hideaki kn-aut-name=福井秀明 kn-aut-sei=福井 kn-aut-mei=秀明 aut-affil-num=3 ORCID= en-aut-name=ChudaMasaki en-aut-sei=Chuda en-aut-mei=Masaki kn-aut-name=忠田正樹 kn-aut-sei=忠田 kn-aut-mei=正樹 aut-affil-num=4 ORCID= en-aut-name=NambaReiko en-aut-sei=Namba en-aut-mei=Reiko kn-aut-name=難波玲子 kn-aut-sei=難波 kn-aut-mei=玲子 aut-affil-num=5 ORCID= en-aut-name=IkedaHisao en-aut-sei=Ikeda en-aut-mei=Hisao kn-aut-name=池田久男 kn-aut-sei=池田 kn-aut-mei=久男 aut-affil-num=6 ORCID= en-aut-name=OtsukiSaburo en-aut-sei=Otsuki en-aut-mei=Saburo kn-aut-name=大月三郎 kn-aut-sei=大月 kn-aut-mei=三郎 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=国立岡山療養所・神経内科 affil-num=2 en-affil= kn-affil=高知県立中央病院・神経科 affil-num=3 en-affil= kn-affil=岡山大学・神経精神医学教室 affil-num=4 en-affil= kn-affil=岡山大学・神経精神医学教室 affil-num=5 en-affil= kn-affil=国立岡山療養所・神経内科 affil-num=6 en-affil= kn-affil=岡山大学・神経精神医学教室 affil-num=7 en-affil= kn-affil=岡山大学・神経精神医学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=895 end-page=902 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Prenatal diagnosis of chromosome abnormalities with cultivated amniotic fluid cells kn-title=羊水細胞培養による染色体異常の出生前診断 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The methods for cultivation of amniotic fluid cells were described.

These phenomena are very rational and suitable for hepatocyte regeneration. 4) The inhibitory activity was separatedly eluted by DEAE-cellulose chromatography of inactive regenerating liver fraction, and new peak that did not exist in normal inhibitory fraction was detected in polyacrylamid gel electrophoresis of regenerating liver same fraction. 5) These phenomena suggest that a possible new anti-inhibitory factor(s) would be formed by partial hepatectomy. en-copyright= kn-copyright= en-aut-name=FujiiToshitake en-aut-sei=Fujii en-aut-mei=Toshitake kn-aut-name=藤井利武 kn-aut-sei=藤井 kn-aut-mei=利武 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一生理学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=877 end-page=882 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effect of isometric handgrip exercise to the left ventricular performance -the evaluation for normal adults by echocardiography kn-title=等尺性握力負荷の左室機能に及ぼす影響―健常成人に対する心エコー図による評価― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Isometric handgrip exercise were performed to evaluate the left ventricular performances in fifteen normal adults by echocardiography.

MIF activity in the mouse transplanted s.c. with 5x10(6) Ehrlich cancer cells first appears markedly in the regional lymph nodes and the MIF activity disappears about 10 days after the cancer transplantation. 2. In three cases (8.6%) out of 36 having benign diseases MIF activity is positive. 3. In measuring the MIF activity of peripheral blood lymphocytes of 71 gastric cancer patients before operation, those showing positive or pseudo-positive activity of MIF are 24 cases, being 33.9% of the total. MIF activity of peripheral blood lymphocytes before operationin the cases of Stage II is 41.7% , in those of Stage III it is 29.0% and in those of Stage IV it is 15.4% , indicating that the positive rate of MIF declines as the cancer progresses. Lymphocytes of the lymph nodes extirpated during operation show a similar tendency. 4. In comparing MIF activity of peripheral blood lymphocytes of gastric cancer patients before operation with that after operation, the activity in Stage II before operation is 41.7% as against 0% after operation, that in Stage III it is 29.0 % before operation and 10.5% after operation, showing amarked decrease, while that in Stage IV, in contrast, rises from 15.4% to 23.1%. Usually the MIF activity disappears when tumor removal is completely performed, but in the cases of progressive cancer the MIF activity seems to be sustained. 5. Looking at the cross reaction, in gastric cancer cases with positive MIF activity for autochthonous antigen they show 42.9% positivity against heterogenous antigen. Besides we have observed the cross reaction between gastric cancer and colon cancer as well as between colon cancer and gastric cancer. The foregoing findings indicate that in human cancer just as in animal cancer MIF activity first appears in the regional lymph nodes, which tends to decrease and disappears as the cancer advances. Since there can be observed a marked cross reaction between gastric cancer patients, MIF would serve as a useful criterion for the discovery of gastric cancer and for the determination of prognosis. en-copyright= kn-copyright= en-aut-name=UchidaYoshio en-aut-sei=Uchida en-aut-mei=Yoshio kn-aut-name=内田善夫 kn-aut-sei=内田 kn-aut-mei=善夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一外科教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=859 end-page=863 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the lipid of rat dental pulp II.

In the extracted lipid components of dental pulps, the peroxidation of phospholipid were marked, but those of choresterol, choresterol ester, mono-,di-, tri-glycerides, and fatty acid (non-esterified) were slightly or negligible. In the phospholipid components, the peroxidation was highly observed in lecithin, phosphatidyl ethanolamine and phosphatidyl serine, and the peroxidation of phosphatidyl ethanolamine showed the most value in them. By the analysis of the fatty acid composition, arachidonic acid was included in the phos-pholipid but not in the triglyceride, suggesting arachidonic acid is substrate of the peroxidation of dental pulps. kn-abstract=1) ラット切歯歯髄のホモゲネートにおいてFe(++)誘導脂質過酸化反応活性が認められた.エックス線全身照射(1000R)したラットより分離した歯髄ホモゲネートのFe(++)誘導脂質過酸化反応は非照射のそれに比して促進がみられた. 2) ラット切歯歯髄脂質の構成脂質中で,過酸化反応を誘起し易い脂質はリン脂質で,中性脂質ではほとんど誘起されなかった. 3) リン脂質中,そのリン脂質構成の大部分をしめるボスファチジルコリン,ホスファチジルエタノールアミン,ホスファチジルセリンにおいて過酸化反応が誘起し得た.中でもホスファチジルエタノールアミンの脂質重量当りの比活性が最も高い値を示した. 4) リン脂質の脂肪酸組成では,アラキドン酸をはじめ,不飽和含量が多く,トリグリセリドではアラキドン酸はみられなかった. en-copyright= kn-copyright= en-aut-name=HashimotoGonosuke en-aut-sei=Hashimoto en-aut-mei=Gonosuke kn-aut-name=橋本郷之助 kn-aut-sei=橋本 kn-aut-mei=郷之助 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部口腔外科学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=851 end-page=858 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the lipid of rat dental pulp I.

The ratio in the irradiated group (3 days after irradiation) did not change. 2) In fatty acid composition of lipid of normal rat incisor pulps, palmitic, oleic, stearic, arachidonic, and linoleic acids were much in this order, and palmitic, stearic and oleic acids were major component accounted for over 78% of the total fatty acids. In that of the irradiated group, the decrease of oleic acid and the increase of arachidonic acid were observed comparing those of normal pulp lipid. 3) The major lipid of normal dental pulps composed of phospholipid, choresterol, triglyceride and choresterol ester, and phospholipid and choresterol accounted for about 45% and 30% of the total lipids, respectively. In the irradiated group, the decrease of choresterol and the increase of choresterol ester were represented. 4) In results of tentative identification by various color reaction on the thin-layer chromatograph, the major phospholipids of dental pulps were lecithin, phosphatidyl ethanolamine and phosphatidyl serine, which accounted for over 90% of the total phospholipids. It is significant that phosphatidyl serine in dental pulp is greater than in any other mammalian soft tissue so far studied. In the irradiated group, it was slightly observed the increment of lecithin and the decrement of phosphatidyl serine, but they are not predominant. kn-abstract=ラット切歯歯髄の脂質組成ならびに脂肪酸組成を解析するとともに,あわせてエックス線全身照射の各々の組成に及ぼす影響を研究し次の如き結果を得た.(1)切歯歯髄の総脂質含量は蛋白量相対比にして0.26の値を得た.エックス線全身照射群(1000R照射後3日目のもの)の歯髄も同様0.26の値を得,その差は得られなかった.(2)正常切歯歯髄の総脂質の脂肪酸組成において,パルミチン酸,オイレン酸,ステアリン酸,アラキドン酸,リノール酸の順に主成分として認められ,前三脂肪酸で78%以上を占めた.エックス線全身照射群においてはオレイン酸の減少,アラキドン酸の増加が認められた.口腔領域への部分照射(1000R)でも同様の傾向がみられた.(3)正常切歯歯髄の脂質構成としてリン脂質,コレステロール,トリグリセリド,コレステロールエステルが主成分として認められ,リン脂質は45 % ,コレステロールは30 % を占めた.エックス線全身照射群ではリン脂質,トリグリセリドの構成比に変動はみられなかったが,コレステロールの減少とコレステロールエステルの増加が認められた.(4)正常切歯歯髄リン脂質の構成を各種呈色反応で仮同定した結果,レシチン,ホスファチジルエタノールアミン,ホスファチジルセリンが主成分として90 % 以上を占めた.特にホスファチジルセリン含量が多いのが注目される.照射群ではレシチンの増加,ホスファチジルセリンの減少など若干の組成比に変動がみられたが,対照との差は有意とは言えなかった. en-copyright= kn-copyright= en-aut-name=HashimotoGonosuke en-aut-sei=Hashimoto en-aut-mei=Gonosuke kn-aut-name=橋本郷之助 kn-aut-sei=橋本 kn-aut-mei=郷之助 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部口腔外科学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=819 end-page=849 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical and experimental study on the influence of cellular immune response in establishment of autotransplantation of autochothonous tumor-Analysis of their relationship by blastogenic activity of lymphoid cell kn-title=悪性腫瘍自家移植の成立におよぼす細胞性免疫能,とくにphytohemagglutininに対するリンパ球幼若化能の影響に関する臨床的ならびに実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=1) T cell population and blastogenic activity against both phytohemagglutinin (PHA) and pokeweek mitogen (PWM) were assayed in twenty patients, whose malignant neoplasma had been eradicated by surgery before more than six months, when the first clinical evidence of the recurrence was observed during the period of postoperative control. A deterioration of the blastogenic activity of the lymphocyte to PHA was highly significant, compaired with that in healthy subjects and patients who have had radical surgery for their neoplasm but showed no evidence of the recurrence. It was noted that this deterioration occurred regardlessly of the interval between the surgery and the recurrence and also of the mode of recurrent lesion. No remarkable differences were observed in the T cell population and the blastogenic activity to PWM among these three groups. 2) Swiss mice were undergone subcutaneous autotransplantation of isolated tumor cells from their own methylcholanthrene-induced leg sarcoma after surgical removal of the tumor. The establishment of the autotransplantation and the growth of the tumor was daily observed and the blastogenic activity of the splenic lymphocyte to PHA was assayed 14 days after the tumor implantation. Neither a period before the tumor take nor cumulative incidence of the take were correlated with the blastogenic activity of the splenic cell. However, the individual size of the tumors 14 days after the transplantation was markedly smaller in mice having the blastogenic activity higher than the mean value in the group than in those having the activity lower than the mean. Thus the reverse correlation between the tumor size and the blastogenic activity ratio were statistically significant (p<0.01). An additional skin homograft performed simultaneously with the tumor inoculation resulted in the apparent increase in the number of the mice showing the blastogenic ratio higher than the mean in the non-grafted control, and this caused further inhibition of the tumor growth, showing also the significant reverse correlatio between the tumor size and the blastogenic ratio (p<0.01). B. C. G. inoculation, before, at and after the tumor transplantation, caused marked decrease in the mitogenic activity of the splenic cell, but the tumor growth was significantly detarded and the reverse correlation between the tumor size and the blastogenic ratio among the individual mice was preserved as in the above two experiments. In mice administered with Cephranthin, daily for 14 successive days starting with the tumor transplantation, the tumor growth inhibition of slight grade was observed as late as 14 days following the tumor inoculation and no significant effect on the blastogenic activity of the splenic cell was observed, and though the reverse correlation above was affirmed it was not highly significant (p<0.05). 3) From the results mentioned above, the author intended to conclude that the reverse correlation between tumor growth and blastogenic activity of the lymphoid cell does exist and even the nonspecific immunopotentiation contribute to bestow the ability for the lymphoid cell to suppress the tumor growth by potentiation of the blastogenic activity, even in mechanism of establishment of autotransplantation of malignant tumor in the subject whose malignant neoplasma was eradicated, as in cancer bearing hosts. Additionally, the possibility that deterioration of the blastogenic activity of the lymphoid cell may play a role of triggering effect for dormant cancer cell to obtain a growing ability was presumed and a possibility of significant contribution to this mechanism of cell- mediated cancer immunity other than that can be assessed by mitogenic activity of the lymphoid cell was also discussed. en-copyright= kn-copyright= en-aut-name=OnoKensaku en-aut-sei=Ono en-aut-mei=Kensaku kn-aut-name=小野監作 kn-aut-sei=小野 kn-aut-mei=監作 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=793 end-page=817 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effect of serum alpha 1-antitrypsin on the fibrinolytic system in cancer patients kn-title=担癌病態におけるα(1)―antitrypsinに関する臨床的研究-とくに根治手術前後における線溶現象への関与について― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The α(1)-antitrypsin (α(1)AT), which comprises more than 90 % of the protein content of the α(1)-globulin, inhibits a variety of enzyme. α(1)AT is the major trypsin inhibitor in human serum and has an important role as antiplasmin in fibrinolytic system. The experiments were carried out to investigate the effect of α(1)AT on fibrinolytic system, measuring serum α(1)AT levels and coagulative and fibrinolytic activities in man. The serum α(1)AT levels were measured in 30 controls, 93 cancer and 107 nonmalignant patients. They were also measured in the postoperative patients who were 7 cases of gastric cancer, 5 of lung cancer, 5 of breast cancer and 5 of cholelithiasis. The serum levels were measured by a single radial immunodiffusion plate (M-partigen) obtained from the Behring Institute. The results obtained were as follows: 1) The levels of α(1)AT were significantly increased in patients with lung cancer, gastric cancer and colon cancer, while those with breast cancer and thyroid cancer remained in normal range. There was a significant correlation between α(1) AT and the clinical stage of lung cancer and gastric cancer. Among nonmalignant patients, AT was significantly elevated in the inflammatory diseases such as lung abscess and hepatitis. 2) α(1)AT had the lowerest level at the end of operation and it exceeded the preoperative value and returned to preoperative level at the 14th day. These changes of α(1)AT were observed both cancer and nonmalignant patients. The plasma fibrinogen levels showed a similar pattern to α(1)AT during postoperative period, whereas d(2)-macroglobulin had no significant changes. The concentration of plasma plasminogen and antithrombin III had been fallen below the preoperative levels by the 7th day and returned at the 14th day. Antitrypsin activities were increased to some extent by the 7th postoperative day. These results suggest that the elevation of α(1)AT is closely related to two factors as follows: a) α(1)AT may increase to neutralize a certain leucocytic protease when leucocytes increase in body. b) The increase in α(1)AT might be due to regulating the plasmin which auguments in cancer, inflammation or postoperative patients, may induce release of antiplasmin whose activity is mainly dependent on α(1)AT. en-copyright= kn-copyright= en-aut-name=OnoYoshihiko en-aut-sei=Ono en-aut-mei=Yoshihiko kn-aut-name=小野好彦 kn-aut-sei=小野 kn-aut-mei=好彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=781 end-page=791 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Histochemical study on catecholamine of substantia nigra of the brain kn-title=黒質のカテコールアミンに関する組織化学的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The distribution of catecholamine of substantia nigra was observed under fluoromicroscopy by Falck-Hillarp method for catecholamine detection. Several mammals (monkey, goat, dog, cat, rabbit, guinea pig, rat and mouse) were used. Substantia nigra of all mammals used consisted of two regions, zona compacta and zona reticularis. Nerve cells and fibers with strong catecholamine-specific fluorescence were observed in zona compacta of all mammals used, but in zona reticularis nerve cells did not contain catecholamine and nerve fibers contained a little catecholamine. Nerve cells which consisted zona compacta of monkey, goat, dog and cat were large and sparsely distributed, while those of rabbit, guinea pig, rat and mouse were small and densely distributed. The strength of fluorescence of the latter animals were stronger than that of the former animals. Thus, the absence of significant differences among animals of distribution and cell shape of nerve cells of subatantia nigra suggest that this region has central role in the function of catecholamine, especially dopaminergic neurons of the brain. en-copyright= kn-copyright= en-aut-name=YokoyamaYoshihumi en-aut-sei=Yokoyama en-aut-mei=Yoshihumi kn-aut-name=横山好文 kn-aut-sei=横山 kn-aut-mei=好文 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一解剖学教室 END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=7-8 article-no= start-page=757 end-page=780 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=19770830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects of total parenteral nutrition on the histological and cytological changes of several organs in rats. kn-title=完全静脈栄養法による各臓器の変化に関する組織学的,細胞学的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The experiment was carried out to investigate the effects of total parenteral nutrition (TPN) on body weight, nitrogen balance and the histological or cytological changes of main organs in rats. TPN was introduced to 59 female Wistar rats of seven weeks after birth, for ten days. The animals were devided into six groups as follows: Group I Control, fed orally by pellets Group II TPN of amino acid-fat-glucose Group III TPN of amino acid-glucose Group IV Fat and glucose Group V Amino acid exclusively Group VI Starvation 1) The body weight increases in Group II and III were 6.7% and 3.6% of the initial value, respectively. However, the increase in body weight of each group was less than that of control. Nitrogen balance study showed that cumulative nitrogens of Group II and III for seven days were 1.10 and 0.93 grams, respectively. 2) Fatty infiltration in the liver was not due to whether TPN consisted of fat or not. When a Cal/N ratio was increased in TPN, liver showed fatty infiltration at the peripheral regions of the lobules. The fatty infiltration seemed to become more diffuse as caloric excess was greater. Electron microscopy of hepatocytes revealed multiple giant lipid droplets in cytoplasm and glycogen cluster localizing around lipid droplets. This suggests that glycogen may change to fat following TPN. 3) TPN caused an atrophy of exocrine pancreas. The atrophy was much greater in Group IV, which was excluded amino acid. Ultrastructurally, pancreatic acinar cells revealed increased FCD (focal cytoplasmic degradation) of various size, augumented flat mitochondria, increased immature zymogen granules and dilatation of rough surfaced endoplasmic reticulum. These results show that deprivation of amino acid from TPN causes impairment to pancreatic acinar cells, even in short period. 4) Infusion of hypertonic glucose or amino acid caused cloudy swelling and vacuolization of renal tubule epithelial cells, which ultrastructurally coincided with the swelling, deformity and vacuolization of mitochondria, low electron density of cytoplasm and increased lysosomes. en-copyright= kn-copyright= en-aut-name=MizobuchiMasayuki en-aut-sei=Mizobuchi en-aut-mei=Masayuki kn-aut-name=溝渕正行 kn-aut-sei=溝渕 kn-aut-mei=正行 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部外科学第二教室 END
