Since then we have found that when this substnce is injeted intravenously into animals, there occur disturbances in the blood, spleen and bone marrow. And also it has become clear that this substance brings about Heinz's body appearance in erythrocytes. As Heinz's body also appears in cancer anemia and it is transformed into hemolysin, it may be assumed that the hemolytic, anemia-inducing substance is contained also in cancer tissue. Upon such assumption we have compared the hemolytic capacity of the extract obtained from the fresh gastric cancer tissue resscted at operation with that of the extract from normal gastric tissue. As the result, we have recognized that this hemolytic, anemia-inducing substance is contained considerably in cancer tissue. en-copyright= kn-copyright= en-aut-name=YamamotoMichio en-aut-sei=Yamamoto en-aut-mei=Michio kn-aut-name=山本道夫 kn-aut-sei=山本 kn-aut-mei=道夫 aut-affil-num=1 ORCID= en-aut-name=NobukiSigeo en-aut-sei=Nobuki en-aut-mei=Sigeo kn-aut-name=信木茂生 kn-aut-sei=信木 kn-aut-mei=茂生 aut-affil-num=2 ORCID= en-aut-name=SiakuTakeru en-aut-sei=Siaku en-aut-mei=Takeru kn-aut-name=塩飽健 kn-aut-sei=塩飽 kn-aut-mei=健 aut-affil-num=3 ORCID= en-aut-name=AkagiKeiko en-aut-sei=Akagi en-aut-mei=Keiko kn-aut-name=赤木瑩子 kn-aut-sei=赤木 kn-aut-mei=瑩子 aut-affil-num=4 ORCID= en-aut-name=SiakuMidori en-aut-sei=Siaku en-aut-mei=Midori kn-aut-name=塩飽緑 kn-aut-sei=塩飽 kn-aut-mei=緑 aut-affil-num=5 ORCID= en-aut-name=IgutiYosiko en-aut-sei=Iguti en-aut-mei=Yosiko kn-aut-name=井口与志子 kn-aut-sei=井口 kn-aut-mei=与志子 aut-affil-num=6 ORCID= en-aut-name=TanimotoJunichi en-aut-sei=Tanimoto en-aut-mei=Junichi kn-aut-name=谷本潤一 kn-aut-sei=谷本 kn-aut-mei=潤一 aut-affil-num=7 ORCID= en-aut-name=KojimaSumikazu en-aut-sei=Kojima en-aut-mei=Sumikazu kn-aut-name=小島澄一 kn-aut-sei=小島 kn-aut-mei=澄一 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=8 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=72 cd-vols= no-issue=3 article-no= start-page=959 end-page=993 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Effect of Respiratory Enzyme Inhibitors on Infection of Rickettsia kn-title=各種呼吸酵素阻害剤のRickettsiaの感染に及ぼす影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Using several kinds of respiratory enzyme inhibitors, the author studied the effect of the inhibitors on infection of rickettsia to mouse. The investigations were carried out in vitro and in vivo and the observations were made from day to day. Moreover, the characters of rickettsia were investigated by the re-inoculation to normal mouse from the culture. The following results were obtained. 1) The infection of rickettsia were found to be suppressed by previous in vitro treatment of rickettsia with any enzyme inhibitors tested, but the suppression effect was varied by hind of inhibitors, its concentration, duration of its action and the concentration of rickettsial suspension. The infection capacity of enzyme inhibitor treated-rickettsia showed a decrease in cases of 5 hours treatment of 10-20 mg malonate, of 1.0 mg monojodo acetic acid or of 1.0 mg fluoride. However, the affection of these inhibitors was vary specific, and found to have caused merely a reduction of infection capacity or a suppression of infection instead of to caused an inactivation of rickettsia. 2) On the contrary the inhibitors did not show an inhibitory effect to the infection of the rickettsia, if the inhibitors were administrated to the mouse to be tested before the attack of rickettsia. Accordingly a fairly difinite infection and the successive multiplication of rickettsia were observed on the previousely inhibitor-treated mouse; upon rare occasions the infection was found to be severe on these treated mouse. 3) The effect of inhibitors also studied by obeorving properties of re-inoculated rickettsia to normal mouse, the rickettsia was taken from the culture on the previously inhibitor-treated mouse. The multiplication of re-inoculated rickettsia was measured by means of LD(50) curve, and was demonstrated that the appearance of symptomes and the days to death after the infection was somewhat delayed on the treated animal compared to the control; but the occurences were almost in the same way as in the control except a short delay of the time. Hence, the affected metabolism of host cell and metabolic system of animal required to multiplication of the rickettsia were supposed to show so much definite effect to the suppression of infection. en-copyright= kn-copyright= en-aut-name=KiyotoMasahiro en-aut-sei=Kiyoto en-aut-mei=Masahiro kn-aut-name=清遠正博 kn-aut-sei=清遠 kn-aut-mei=正博 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=72 cd-vols= no-issue=3 article-no= start-page=951 end-page=958 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Influences of OX (unsaturated fatty acidextract) on Ehrlich's Ascites Tumor cells kn-title=工ールリッヒ癌に及ぼすOXの影響に就いて en-subtitle= kn-subtitle= en-abstract= kn-abstract=In view of the fact that there may be two possible actions in radiation distrurbaces in vivo, namely, one acting directly and the other acting indirectly, and on the assumption that these actions, persisting quite a long time after irradiation, induce specific substance in the irradiated nimals, Yamamoto of our department, has succeeded in isolating unsaturated fatty acid substance (OX) specific to the irradiated animals. With the purposa to find out what influences this substance (OX) will have on Ehrlich's ascites tumor cell, the author studied its effect on the number, mitotic phases and DNA ontents of the cancer cells. Test animals used are 80 mice each wighing about 15-20g. To these animals 0.2cc cell suspension of Ehrlich's ascites tumor cell is transplanted intraperitoneally and one week after the transplantation 0.2cc of 2%-, 1%-, 0.5%- OX substance is injected intrapeitoneally to these animals. By observing the changes in the cell counts, mitotic phase, and the DNA contents in each cell (with spectrophotometry) at the intervals of 1, 3, 6, 9, 12, and 24 hours after the injection of OX substance, and the following results were obtained: The number of cancer cells has been found markedly decreased; nomely, after one hour it is down to 78 per cent of the original count; down to 44per cent after 9 hours; and clown to 46.2 per cent after 24 hours. As for the mitotic phases, metaphase, anaphase telophase have been increased and the number of cells undergoing mitosis is diminished. Moreover, as for the DNA contents per cell, there can be observed an increase ni the number of cells with a markedly small amount of DNA, while the cells undergoing duplication due to mitosis have been found decreased in number. From these facts it is concl ded that OX substance acts on Ehrlich's ascites tumor cells as to induce the following disturbances: (1) cell destruction, (2) impairment of the activity in mitotic apparatus, (3) disturbance of the DNA synthesis, and (4) elicits atypical cell divistion. en-copyright= kn-copyright= en-aut-name=ItamiMotoya en-aut-sei=Itami en-aut-mei=Motoya kn-aut-name=伊丹尤也 kn-aut-sei=伊丹 kn-aut-mei=尤也 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=72 cd-vols= no-issue=3 article-no= start-page=943 end-page=949 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A CLINICAL STUDY OF THE INTRAVENOUS THIAMYLAL SODIUM ANESTHESTA FROM THE STANDPOINT OF THE BLOOD AND INTERSTITIAL FLUID PART II THE RELATIONSHIP BETWEEN THE ANESTHESIA DURATION AFTER ADMINISTRATION OF THIAMYLAL SODIUM AND BLOOD AND INTERSTITAL FLUID kn-title=体内水分電解質分布とThiamylal Sodium静脈麻酔との関係に関する臨床的研究 第2編 体内水分電解質のThiamylal Sodium静脈麻酔における麻酔時間に及ぼす影響について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Twenty-one patients were anesthetized by intravenous injection of thiamylal sodium and the relationships between the duration of anesthesia and the blood and interstitial fluid were studied. 1) A parallel correlation was seen between the anesthesia duration and the water content of plasma. 2) A reverse correlation was found between the sleeping time of anesthesia and quantity of the total plasma protein. 3) No interrelatiohships were found between the duration of anesthesia and hematerit, water content of blood, serum natrium, serum chloride, serum pottasium and plasma volume. 4) A reverse correlation was seen between the sleeping time of anesthesia and the interstitial fluid volume. en-copyright= kn-copyright= en-aut-name=MatsudaSumizo en-aut-sei=Matsuda en-aut-mei=Sumizo kn-aut-name=松田住蔵 kn-aut-sei=松田 kn-aut-mei=住蔵 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1(陣内)外科教室 END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=3 article-no= start-page=933 end-page=942 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A CLINICAL STUDY OF THE INTRAVENOUS THIAMYLAL SODIUM ANESTHESIA FROM THE STANDPOINT OF THE BLOOD AND INTERSTITIAL FLUID PART I CHANGES IN BLOOD AND INTERSTITIAL FLUID BY INTRAVENOUS THIAMYLAL SODIUM ANESTHESIA kn-title=体内水分電解質分布とThiamylal Sodium静脈麻酔との関係に関する臨床的研究 第1編 Thiamylal Sodium静脈麻酔前後における体内水分電解質分布の変動について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Twenty-one patients were anesthetized by intravenous injection of thiamylal sodium and changes in blood and interstitial fluid were observed before and after anesthesia. 1) The specific gravity of blood and plasma, plasma protein and hematcrit slightly increased after intravenous administration of thimylal sodium, while the water content of blood and pleasma decreased. 2) Among the plasma electrolytes, plasma nartrium and chloride decreased, while plasma pottasium increased. 3) A decrease of plasma volume and an increase of interstitial fluid were observed. 4) The changes of factors mentioned above is regarded to be caused not only by blood concentrasion but also by transmission of plasma fluid to extracellular fluid. en-copyright= kn-copyright= en-aut-name=MatsudaSumizo en-aut-sei=Matsuda en-aut-mei=Sumizo kn-aut-name=松田住蔵 kn-aut-sei=松田 kn-aut-mei=住蔵 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第1(陣内)外科教室 END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=3 article-no= start-page=927 end-page=931 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Comparative Study on the Effect of Aureomycin, Chloromycetin, and Streptomycin on the Bacterial Respiration kn-title=微生物の呼吸に対するオーレオマイシン,クロロマイセチン及びストレプトマイシンの作用 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This experiment was performed to investigate the effect of aureomycin, chloromycetin, and streptomycin upon the oxidation of several substrates by Sh. flexneri 2a and E. coli communis.

The inhibitory rate has no relation to the preincubation time of a mixture of aureomycin and a cell suspension. 2) A high concentration (200γ/ml) of chloromycetin slightly inhibits the oxidation of amino acids such as glutamate and aspartate.

The oxidation of proposed substrates by Sh. flexneri 2a is not also prevented by streptomycin.

The authors performed this experiment in order to find out the differencies of the tryptophan metabolism between streptomycin-sensitive and streptmycin-resistant Shigella flexneri 2a. The results were as follows: 1. When streptomycin-resistant strains were grown in the streptomycin-containing medium, they have quantitatively lower tryptophanase activity than streptomycin-sensitive strains. 2. Streptomycin-resistant strains restores tryptophanase activity when streptomycin is absent in the growth medium, but they are resistant to streptomycin (10,000γ/ml). 3. Tryptophanase activity of both strains is inhibited slightly by divalent metal ions such as Mg, Fe, and Mn, but the inhibitive action of Cu is very remarkable. Natrium azide and arsenite have no effect. Vitamin B(6) and 2.4-dinitrophenol accerelates indole production from tryptophan by this organism. 4. Of the the various antibiotics aureomycin inhibits most markedly tryptophanase activity and chloromycetin does slightly, but streptomycin has no influence. 5. Tryptophanase is an adaptive enzyme, and considered to have essentially no relation to streptomycin-resistant mutation. en-copyright= kn-copyright= en-aut-name=KawaiKiyoshi en-aut-sei=Kawai en-aut-mei=Kiyoshi kn-aut-name=川井潔 kn-aut-sei=川井 kn-aut-mei=潔 aut-affil-num=1 ORCID= en-aut-name=NishiiEmiko en-aut-sei=Nishii en-aut-mei=Emiko kn-aut-name=西井笑美子 kn-aut-sei=西井 kn-aut-mei=笑美子 aut-affil-num=2 ORCID= en-aut-name=TakahashiManabu en-aut-sei=Takahashi en-aut-mei=Manabu kn-aut-name=高橋学 kn-aut-sei=高橋 kn-aut-mei=学 aut-affil-num=3 ORCID= en-aut-name=HonmatuKakushi en-aut-sei=Honmatu en-aut-mei=Kakushi kn-aut-name=本松格史 kn-aut-sei=本松 kn-aut-mei=格史 aut-affil-num=4 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 affil-num=4 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=72 cd-vols= no-issue=3 article-no= start-page=901 end-page=913 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Physiological Studies on the Metabolic Activities of Streptomycin-Resistant B. dysentheriae U.

The pH optimum for oxidation of pyruvate of resistant strain is pH 5.6-6.0, whereas that of susceptible strain is pH 7.0-7.5. 2) The consumption rate on pyruvic acid substrate by resistant strain is significantly less than by susceptible strain. 3) Both resistant and susceptible strains oxidizes pyruvic acid via succinate. Pyruvate accumulates during the oxidation of the tricarboxylic acid cycle intermediates such as succinate, malate, fumarate, α-ketoglutarate by resistant and susceptible strains. 4) Aspartic-glutamic transamination has been demonstrated in susceptible strain under aerobic condition with both aspartic acid and glucose added. 5) The oxidation of pyruvate of susceptible strain can be accerelated more rapidly by divalent metal ions such as Mg??, Fe??, Mn?? than that of resistant strain. 6) Panthotenate accerelates more reasonably the respiration of pyruvie acid by susceptible strain than by resistant strain. 7) The significance of these results in relation to the presence of the citric acid cycle in the organism is discussed, and it is considered possible that an significant difference in metabolic activities between resistant and susceptible strains exists in the metabolic pathway from pyruvate to succinate in the citric acid cycle. en-copyright= kn-copyright= en-aut-name=KawaiKiyoshi en-aut-sei=Kawai en-aut-mei=Kiyoshi kn-aut-name=川井潔 kn-aut-sei=川井 kn-aut-mei=潔 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=72 cd-vols= no-issue=3 article-no= start-page=889 end-page=899 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Physiological Studies on the Metabolic Activities of Streptomycin-Resistant B.

This paper is concerned with the examination of the glucose metabolism of streptomycin-susceptible and streptomycin-resistant strains of Sh. flexneri 2a. The resistant strains was obtained by serial transfers in progressive levels of streptomycin. This resistant variant could withstand at least 10,000γ per ml of streptomycin. 1) The oxidative abilitys of the resistant strains is considerably less on pyruvate among the components of the citric acid cycle than is that of the susceptible strain. 2) Pyruvic acid, lactic acid, and acetic acid accumulates during the oxidation of glucose by resistant and susceptible strains. The amount of pyruvic acid produced from glucose by resistant strain is more than that by susceptible strain. In the rate of consumptions of glucose between resistant and susceptible strains there is much less difference. 3) No significant difference between both strains is detected in anaerobic metabolism of glucose. 4) Resistant strains which has grown on continued subculture by serial transfer in the medium not containing streptomycin possess still these properties. This culture was also found to be resistant to at least 10,000γ per ml of streptomycin. 5) It is suggested that streptomycin-resistant and susceptible strains dissimilates glucose mainly by way of Embden-Myerhof pathway, and also have Warbung-Dickens pathway as an alternate pathway. 6) Streptomycin-susceptible strain growes more rapidly than streptomycin-resistant strain in shaking culture. 7) These results suggests that streptomycin-resistant strain is more fermentative in the metabolism of glucose than streptomycin-susceptible strain, and a significant difference between streptomycin-resistant and streptomycin susceptible strains exists in pyruvate metabolism and its terminal respiration system. en-copyright= kn-copyright= en-aut-name=KawaiKiyoshi en-aut-sei=Kawai en-aut-mei=Kiyoshi kn-aut-name=川井潔 kn-aut-sei=川井 kn-aut-mei=潔 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=72 cd-vols= no-issue=3 article-no= start-page=845 end-page=854 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cytological Studies on the Aspirated Fluid with the Phase-Contrast Microscope Part 1.

As the results the following conclusions were arrived at: 1. The majority of mouse phagocytes have the characteristics similar to those of monocytes and histiocytes. 2. In the higher animals such as rats and rabbits a greater portion of them show flagellar pseudopodia and the aggregating tendency of highly reflactile granules and the distribution of mitochondria along the groove of the nucleus. And their nuclear membrane is thin and the nuclei are solid with a complicated shape, and the nuclear substance is soft but without any nucleoles. All of these findings become quite similar to those of monocytes, and in dogs and cats they can hardly be distinguished from monocytes. In the case of normal human phagocytes most of them show degeneration but even these cells reveal the characteristics very close to those of monocytes but far different from those of histiocytes. Even in the chicken phagocytes an unexpectedly large portion of them possess marked characteristics of monocytes. 3. As for the movement of these cells it is minimal, differing from blood monocytes this point, but it seems that this is due to the adaptation peculiar to the circumstances as ascites. From these findings it can be concluded that the ascitic cells possess characteristics far different from those of histiocytes but extremely similar to those of monocytes. en-copyright= kn-copyright= en-aut-name=KamuraJunta en-aut-sei=Kamura en-aut-mei=Junta kn-aut-name=嘉村淳太 kn-aut-sei=嘉村 kn-aut-mei=淳太 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=72 cd-vols= no-issue=3 article-no= start-page=831 end-page=844 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Sulfur Metabolism in Infants Part 2.

In the infants under breast feeding at the age of 1-2 months, 3-4 months, and 5-6 months old the average sulfur retention at each period has bead 25.7, 33.7, and -0.53 per cent respectively. Similarly in the infants under artificial feeding at the same age range the average retenrion has beed 35.1, 48.6 and 40.4 per cent respectively. 2. In the case of the infants under breat feeding at the age of 5-6 months old the quantity of sulfur retained gives a negative value, but this seems to be due to an increased urinary excretion of sulfur in the process of the conversion of cartilage to bone. 3. The nitrogen retention rate shows no difference due to feeding methods. 4. Nitrogen-sulufr ratio (N/S) of the retention differs according to the method of feeding. Namely, the ratio N/S in infants under breast feeding is 25.2 while that in infants under artificial feeding is 18.8. 5. N/S values of the retention in infants under breast feeding are higher than those in infants under artificial feeding. This fact indicates that sulfur in breast milk is more effective than that in cow's milk for increasing the quantity of nitrogen to be retained, and this in turn seems to be due to the action of cystine-sulfur contained in breast milk. en-copyright= kn-copyright= en-aut-name=HamadaGibun en-aut-sei=Hamada en-aut-mei=Gibun kn-aut-name=濱田義文 kn-aut-sei=濱田 kn-aut-mei=義文 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大挙医学部小児科学教室 END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=3 article-no= start-page=821 end-page=830 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Sulfur Metabolism in Infants Part I. Some Suggestion for the Quautative Analysis of Total Sulfur in Milk, Faces and Urine and the Total Sulfur Contents in Various Milk kn-title=乳児の硫黄代謝に関する研究 第1編 乳汁,屎及び尿中の総硫黄定量法の考案並びに各種乳汁中の総硫黄量 en-subtitle= kn-subtitle= en-abstract= kn-abstract=There are numerous articles concerning the estination of total sulfur in organic substances and yet the results obtained hitherto are not by any means quite satisfactory. The gratest difficulty encountered in the estination of sulfur seems to lie in the insufficient ashing of the substance. Therefore, the author studied various ashing metheds and finally modified Bethge's wet ashing in the following manner: 1, Ammoniated vanadium (NH(4)VO(3)) is added as an oxidizing catalyst. 2. As an indicator of the complete oxidation potassium chromate (K(2)Cr(2)O(7)) is used. 3. The ratio of acid mixture is set in the proportion of three parts perohloric acid to two parts nitric acid. 4. The reduction mixture is placed into an ampule filled with pitrogan immediately after it is prepared and is sealed tightly, and the quantity of the mixture to be added is increased. By the modified method mentioned above it has been possible to raise the recovery rate of sulfur added as much as 95.4 per Gent, proving that this method is sufficiently useful for the estimation of the total sulfur in milk, urine and faces. In the estimations of total sulfur of various milk such as breast milk, milk on the market and 18% solution of regulated powered milk the average contents of total sulfur have been found to be 11.7 mg and 31.8 mg per dl respectively. en-copyright= kn-copyright= en-aut-name=HamadaGibun en-aut-sei=Hamada en-aut-mei=Gibun kn-aut-name=濱田義文 kn-aut-sei=濱田 kn-aut-mei=義文 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部小児科教室 END start-ver=1.4 cd-journal=joma no-vol=72 cd-vols= no-issue=3 article-no= start-page=811 end-page=820 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Serum Hepatitis Resulted from Blood Transfusion kn-title=輸血による血清肝炎について en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years there have been many cases, with increasing frequency, of serum hepatitis resulted from blood transfusion. The purpose of this study was to investigate the incidence, clinical feature, prognosis and prophylaxis of serum hepatitis followed by blood transfusion. The results obtained were as follows; 1) Incidence of serum hepatitis among the patients who had blood transfusion at local institutions in Okayama City was 3.3% in 1957 and 4.7% in 1958, on the other hand, at Okayama University Hospital in 1958 it was 5.0% in the First Surgical Division, 5.4% the Second Surgery and 5.2% OBGYN respectively. The patients with serum hepatitis had received the amount 2,600 to 1,120 cc of blood, whereas 810 to 1,120 cc in the cases who never developed serum hepatitis after blood transfusion. 2) Mean incubation period was 72.8 days ranging 19 to 180 days calculated from the date of last blood transfusion. Prodremal stage varied from 1 to 20 days, average 6.1 days, icteric stage 7 to 15 days, average 35.8 days, and convalescent stage 7 to 200 days, average 30.0 days. 3) Characteristic initial symptoms were anorexia, malaise and jaundice by which fairly number of the cases noticed the onset of the disease. Few had febrile course but low grade in most of the cases. 4) Laboratory data were obtained from the 20 cases of serum hepatitis admitted to our First Mebical Division. Serum bilirubin showed the maximum level on the 10 th day, average 13.0 mg% . No significant changes were noted in peripheral blood picture but for a slight initial monocytosis. SGO-T and SGP-T presented a elevation earlier than that of serum bilirubin, maximum on or about the 5 th day and then decreased abruptly. Serum colloidal liver function tests; in initial stage, positive Takata's reaction in 51.%, positive CCF 46% and TTT 58% were noted, but even after 100 th day Takata's reaction was positive in 25% of the cases. 5) Follow-up studies were made on 49 serum hepatitis cases discharged from our hospital with complete recovery. 69% of these had subjective symptems in some sort or another. Enlargement of the liver was noted in 20% of the cases. 33 cases were studied with special reference to liver function tests and liver biopsy. It was revealed that 43% of the cases still had impairment of liver function and that by means of liver biopsy, postnecrotic cirrhosis was found 9.1% of the cases. Therefore, the prognosis of serum hepatitis of this type was considered to be grave. 6) For the purpose of prophylaxis, 300 to 600 mg of gamma globulin was simultaneously administered on blood transfusion in 38 cases. Inspite of this, 4 cases suffered from serum hepatitis later on, and no definite prophylactic effect of gamma globulin was noted. en-copyright= kn-copyright= en-aut-name=KosakaKiyowo en-aut-sei=Kosaka en-aut-mei=Kiyowo kn-aut-name=小坂淳夫 kn-aut-sei=小坂 kn-aut-mei=淳夫 aut-affil-num=1 ORCID= en-aut-name=NagashimaHideo en-aut-sei=Nagashima en-aut-mei=Hideo kn-aut-name=長島秀夫 kn-aut-sei=長島 kn-aut-mei=秀夫 aut-affil-num=2 ORCID= en-aut-name=YamabukiTakahiro en-aut-sei=Yamabuki en-aut-mei=Takahiro kn-aut-name=山吹隆寛 kn-aut-sei=山吹 kn-aut-mei=隆寛 aut-affil-num=3 ORCID= en-aut-name=YamamotoShigeru en-aut-sei=Yamamoto en-aut-mei=Shigeru kn-aut-name=山本繁 kn-aut-sei=山本 kn-aut-mei=繁 aut-affil-num=4 ORCID= en-aut-name=UedaYutaka en-aut-sei=Ueda en-aut-mei=Yutaka kn-aut-name=植田胖 kn-aut-sei=植田 kn-aut-mei=胖 aut-affil-num=5 ORCID= en-aut-name=EndoKenichi en-aut-sei=Endo en-aut-mei=Kenichi kn-aut-name=遠藤憲一 kn-aut-sei=遠藤 kn-aut-mei=憲一 aut-affil-num=6 ORCID= en-aut-name=KusudoHiroshi en-aut-sei=Kusudo en-aut-mei=Hiroshi kn-aut-name=楠戸宏 kn-aut-sei=楠戸 kn-aut-mei=宏 aut-affil-num=7 ORCID= en-aut-name=OnoNobuhiro en-aut-sei=Ono en-aut-mei=Nobuhiro kn-aut-name=小野延宏 kn-aut-sei=小野 kn-aut-mei=延宏 aut-affil-num=8 ORCID= en-aut-name=KobashiNobuo en-aut-sei=Kobashi en-aut-mei=Nobuo kn-aut-name=小橋暢夫 kn-aut-sei=小橋 kn-aut-mei=暢夫 aut-affil-num=9 ORCID= en-aut-name=AsadaKiyotaka en-aut-sei=Asada en-aut-mei=Kiyotaka kn-aut-name=浅田清隆 kn-aut-sei=浅田 kn-aut-mei=清隆 aut-affil-num=10 ORCID= en-aut-name=KajiMasayoshi en-aut-sei=Kaji en-aut-mei=Masayoshi kn-aut-name=加地正義 kn-aut-sei=加地 kn-aut-mei=正義 aut-affil-num=11 ORCID= en-aut-name=KitagawaToshinori en-aut-sei=Kitagawa en-aut-mei=Toshinori kn-aut-name=北川紀典 kn-aut-sei=北川 kn-aut-mei=紀典 aut-affil-num=12 ORCID= en-aut-name=ShinoharaToshio en-aut-sei=Shinohara en-aut-mei=Toshio kn-aut-name=篠原敏夫 kn-aut-sei=篠原 kn-aut-mei=敏夫 aut-affil-num=13 ORCID= en-aut-name=TakakiTadateru en-aut-sei=Takaki en-aut-mei=Tadateru kn-aut-name=高木直輝 kn-aut-sei=高木 kn-aut-mei=直輝 aut-affil-num=14 ORCID= en-aut-name=NishidaTakeshi en-aut-sei=Nishida en-aut-mei=Takeshi kn-aut-name=西田彪 kn-aut-sei=西田 kn-aut-mei=彪 aut-affil-num=15 ORCID= en-aut-name=NagoshiKazuma en-aut-sei=Nagoshi en-aut-mei=Kazuma kn-aut-name=名越一馬 kn-aut-sei=名越 kn-aut-mei=一馬 aut-affil-num=16 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 affil-num=5 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=6 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=7 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=8 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=9 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=10 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=11 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=12 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=13 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=14 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=15 en-affil= kn-affil=岡山大学医学部第一内科教室 affil-num=16 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=72 cd-vols= no-issue=3 article-no= start-page=801 end-page=810 dt-received= dt-revised= dt-accepted= dt-pub-year=1960 dt-pub=19600228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Epidemiological Observations on Infectious Hepatitis Prevailed in Okayama Prefecture kn-title=岡山県における流行性肝炎の流行に関する検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=6246 infectious hepatitis cases treated at 25 hospitals located in Okayama Prefecture during the last six years, 1952 to 1957, were studied mainly from the epidemiological point of view, and the following results were obtained. 1) Infectious hepatitis has been prevailed all over the prefecture since the initial epidemic in 1951. As the mode of epidemic became protracted, chronic and abortive forms were prone to increase in number. The ratio of total patients to infectious hepatitis cases was 1.27 per cent. 2) Extensive infections among villagers were noted in 73 hamlets, and it was presumed that the epidemic has been prevailed over the whole prefecture taking a hamlet, village or a town as unit. Infections among family were noted in 62 families, however, fnrther detailed study in the epidemic areas might show the higher morbidity. It was not certain whether these infections were entirely family or simultaneous infections. 3) As to seasonal occurence, considerable number of cases had onset of the disease during the period of early summer to early fall. 4) As to age, it has ranged mostly from the second to third decade, rather many in children but not rare in the aged. As to sex, predominant in males in general, but considerable differences were seen among hospitals and times. No definite relationship was noted between the epidemc and sex. 5) Throughout the last six years there have been 38.7 per cent of chronic hepatitis cases. In 41.3 per cent of the whole patients presented jaundice in their clinical courses. The fact that the longer the period of the epidemic the more increase increase in anicteric cases was noted. 6) Two year's follow-up studies after the epidemic, showed 209 of relapsed cases in whom 36.4 per cent were icteric. 7) 110 cases has jaundice, which was thought to be infectious hepatitis, in the past. Some of them were presumably reinfections or superinfections but definite conclusion could not be made. 8) 20 cases of fulminant hepatitis, malignant type of infectious hepatitis, and 6 cases of protracted form were studied. 22 cases of them were fatal. Such severe hepatitis patients were seen mainly in males of the second and third decades. 9) 61 cases (0.98%) developed postnecrotic cirrhosis, and 10 cases of them were fatal. 10) Serum hepatitis was noted in 1.6 per cent of the whole patients seen in Medical Services at 18 hospitals in Okayama Prefecture during the last six years, 1952 to 1957. No definite correlation between the epidemic of infectious hepatitis and outbreak of serum hepatitis was noted. en-copyright= kn-copyright= en-aut-name=KosakaKiyowo en-aut-sei=Kosaka en-aut-mei=Kiyowo
