Wir beschrieben oben einen Fall von chronischer myeloischer Leukamie verbunden mit Typhus abdominalis, wobei wir unter anderem die Krankengeschichte und die Therapie hervorhoben. Durch die Ansteckung mit Typhus abdominalis verkleinerte sich der Milztumor schnell und rasch, begleitet von einer Verminderung der absoluten Zahl und des Prozentsatzes der pathologischen Leukozyten. Dies war am deutlichsten nach dem Verschwinden des Fiebers, wenn es auch nur vorubergehend war. Die Injektionen von Autovakzin sowie Kitasato-Typhusvakzin gaben dieselben Resultate, soweit der Milztumor und das Blutbild in Betracht kommen. Hierbei konnten keine Nebenwirkungen auf die allgemeinen und lokalen Befunde beobachtet werden, aber anders wirkte die perorale Anwendung von ,,Bilivaccin antityphique". Anhang : Die Herstellung des Autovakzins. Der Stamm des Autovakzins, das wir vom 12. Jun. bis 7. Jul. benutzten, wurde am 20. Apr. aus dem Krankenblut nach der Anreicherungsmethode mit Galle-Glyzerin-Nahrflussigkeit gewonnen. Wir suspendierten die Bazillen, die frisch auf der gewohnlichen Agarplatte verpflanzt und kultiviert wurden, in einer 0.5%igen Karbolsaure-physiologischen Kochsalzlosung im Verhaltnis von einer Ose zu 10 cc, dann erhitzten wir die Suspension im Wasserbad von 60℃ eine halbe Stunde lang. Darauf uberzeugten wir uns vom Absterben der Bazillen, indem wir die Suspension auf die Drygalski-Conradische Nahrplatte verpflanzten und auch gleichzeitig ihre Anreicherung in der Galle-Glyzerin-Nahrflussigkeit anstrebten. Beim Gebrauch wurde dieser Suspension wieder die Kochsalzlosung bis auf 40 cc zugesetzt.

Die Gallen- sowie Gallensaureausscheidung aus der Gallenblasenfistel des Hundes wird durch subkutane Zufuhr des aus der Krotengalle in der Laichzeit bereiteten Alkoholextraktes vermehrt.

1. Die Ausscheidung von Kreatin im Harn von normalen Kaninchen wird durch Zufuhr von Cholsaure vermehrt, dagegen durch Adrenalin vermindert, wahrend die von Kreatinin durch Cholsaure etwas vermindert, dagegen durch Adrenalin vermehrt wird und zwar wird die gesamte Kreatinkorperausscheidung im Harn durch Cholsaure vermindert, dagegen durch Adrenalin vermehrt. 2. Die Ausscheidung von Kreatin im Harn wird durch Orcheotomie stark herabgesetzt, wahrend die von Kreatinin dadurch vermehrt wird. 3. Bei orcheotomierten Kaninchen zeigt sich ein ganzlich umgekehrtes Verhalten : die Ausscheidung von Kreatin im Harn wird durch Cholsaure vermindert, dagegen durch Adrenalin vermehrt, wahrend die von Kreatinin durch Cholsaure vermehrt, dagegen durch Adrenalin vermindert wird, und zwar wird die gesamte Kreatinkorperausscheidung im Harn durch Cholsaure vermehrt durch Adrenalin aber vermindert. 4. Bei normalen Kaninchen setzt die Zufuhr von Atropin die Kreatininausfuhr im Harn herab, dagegen vermehrt sie die Zufuhr von Ergotamin etwas, wahrend Atropin die Kreatinausfuhr im Harn vermehrt, Ergotamin dagegen sie stark vermindert und zwar wird die gesamte Kreatinkorperausfuhr sowohl durch Atropin als auch durch Ergotamin nicht merklich beeinfluβt. 5. Bei orcheotomierten Kaninchen zeigt der Einfluβ von Atropin und Ergotamin auf die Kreatinkorperausscheidung im Harn ein gerade umgekehrtes Verhalten : die Ausscheidung von Kreatin im Harn wird durch Atropin stark vermindert, durch Ergotamin dagegen stark vermehrt, wahrend die von Kreatinin im Harn durch Atropin etwas vermehrt, durch Ergotamin dagegen etwas vermindert wird und zwar bleibt die gesamte Kreatinkorperausscheidung im Harn durch Atropin sowie durch Ergotamin fast unbeeinfluβt. Die vegetativen Nervengifte beeinfluβen das Gleichgewicht zwischen Kreatin und Kreatinin. 6. Die Kreatinausscheidung im Harn von orcheotomierten Kaninchen wird durch Zufuhr von Hodenextrakt stark vermehrt, wahrend die Kreatininausscheidung dadurch etwas vermindert wird, wobei die gesamte Kreatinkorperausscheidung im Harn durch Zufuhr von Hodenextrakt etwas vermindert wird. Die Funktion des Hodens hangt also mit der Kreatinbildung eng zusammen ; letztere kann durch die vegetativen Nervengifte stark beeinfluβt werden.

A 76-year old farmer ingested 100 g of chlorphenamidine (Galectron), a plant acaricle, for the purpose of suicide. Gastric lavage was performed and the patient survived. Methemoglobinemia was noted after emergency treatment and was still present at 20 hours after ingestion of the compound. The patient was lethargic for at least 50 hours. Moderate neutrophilic leukocytosis and kidney injury were observed.

A simple method is described for determing thyroxine binding proteins in human serum by electrophoresis at pH 8.6, using cellulose acetate membrane as the supporting medium. The procedure had high reliability in sera of normal subjects, pregnant women and patients with decreased thyroxine binding capacity of thyroxine binding globulin.

Cells from methylcholanthrene-induced tumor (MC-tumor), Ehrlich ascites cancer or mouse ascites hepatoma (MH-134) were subcutaneously implanted in dorsal area of mice to examine the specific cell mediated immunity following implantation. The migration index (MI) of lymphocytes was determined at various time periods after cell transplantation. The MI-activity increased under all three implantations, reached maximum at a certain period, decreased gradually and disappeared. The maximum MI-activity coincided with the proliferation period of the implanted tumor cells. This peak occurred on the tenth postimplantation day with MC-tumors, on the fifth day with Ehrlich ascites cancer and on the sixth day with MH-134 cancer. In lymphoid tissues of animals with MC-tumor and Ehrlich ascites cancer, strong MI-activity appeared early in the regional axillary lymph nodes, while weak activity was observed consistently in the distant mesenterial lymph nodes. The MI-activity of the splenic lymphoid cells resembled the axillary lymph nodes cell activity. The MI-activity of venous blood lymphoid cells was parallel to the average value of lymphoid cells of the spleen and axillary and mesenterial lymph nodes.

The relationship between muscle activity at the terminal region of the common bile duct and the duodenal muscle was examined in rabbits. The rhythmic muscle activity in the terminal region was synchronous with duodenal muscle activity. The activity of the latter muscle preceded the former. The activity at the terminal region synchronous with the rhythmic activity of the duodenal muscle sometimes disappeared spontaneously. The muscle activity of the ampulla and the spincter at the terminal region was sometimes independently lost. The conduction of excitation from the duodenal muscle to the terminal region appeared to be performed at several sites. The existence of a "conduction-shunt path" between the terminal region and the duodenum, as well as between the ampulla and the sphincter appeared probably. Some quantitative differences were found between the spincter, ampulla and duodenum in inhibitory effects to stimulation of splanchnic nerves and reflex effects and to excitatory effects of cholecystokinin-pancreoxymin and caerulein. These results seem to indicate that the sympathetic nerves and the intramural cholinergic neurones controlling these region carry out activities quantitatively different from each other.

HB surface antigen (HBs Ag) was detected using the enzyme-labelled antibody technique on routinely processed liver biopsy material fixed in Bouin's fixative and embedded in paraffin. Of 85 examined specimens, 45 cases were HBs Ag positive by both the immunofluorescent test and the enzyme labelled antibody technique. The remaining 40 cases were negative by both techniques. The specificity of HBs Ag detected by the enzyme-labelled antibody technique was confirmed by the blocking test using guinea pig specific HBs antibody. The results indicate that the enzyme-labelled antibody technique may be useful for detecting HBs Ag on routine paraffin sections.

Hepatitis B core antigen (HBc Ag) and hepatitis B surface antigen (HBs Ag) were detected in the liver tissue of a patient with chronic aggressive hepatitis by the immunofluorescent complement technique. The presence of anti-HBc was examined by the same method in 67 human sera previously tested for HBs Ag, anti-HBs and s-GPT levels. HBc Ag was localized mainly in the nucleus and sometimes in the cytoplasm of the hepatic cells. HBs Ag was found only in the cytoplasm. The focal area of HBc Ag positive hepatic cells seemed to correspond to the HBs Ag positive cells. Double staining demonstrated the simultaneous presence of HBs Ag and HBc Ag in individual cells. Anti-HBc positive serum was found in 46 (68.7%) cases. Forty-eight (71.6%) indicated a combination of HBs Ag and anti-HBc.

In order to approach human cancer immunotherapy, the author carried out the immunotherapy with BCG on mice having homotransplanted cancer, observed the posttransplantation results with lapse of time, conduced daily macrophage inhibition test (MI test) and found the immunotherapy to be effective. At the same time the MI test proved to be a useful criterion in determining the course of cancer progress and effectiveness of the immunotherapy.

Phosphate-binding protein(s) was found in the inner mitochondrial membrane of calf heart by Sephadex G-200 and G-25 gel filtration. The binding activity was inhibited by N-ethylmaleimide and competed by a large amount of cold phosphate. The amount of phosphate bound to the fraction was 29 nmoles per mg of protein. Affinity chromatography with phosphate-bound Sepharose 4B confirmed the presence of phosphate-binding protein(s) in the active fraction of mitochondrial membrane fractionated by gel filtration.

In order to formulate an early diagnostic method for acute rejection after kidney transplantation, macrophage migration inhibition test (MIT) was carried out with lapse of time after inbred rat kidney allotransplantation. The mean survival time of rat kidney allograft was found to be 7.07 +/- 1.34 days. On the other hand, in the group treated with rabbit anti-rat lymphocyte serum (ALS) the mean survival time was lengthened to 14.15 +/- 2.14 days (p less than 0.05). The corresponding antigen used for MIT was prepared with donor kidney by ultrasonication, and its protein concentration at 180 mug/ml was the most optimal as not to elicit non-specific inhibition of macrophages. In the control group, activity of macrophage inhibitory factor (MIF activity) turned positive 3 days after the transplantation, and it became strongly positive by 5 or 7 dyas at the period when rejection crisis appeared frequently. ALS-treated group showed a lower MIF activity than the control group (p less than 0.05) and on 7-12 dyas before rejection crisis appeared frequently, MIF activity became strongly positive. These findings suggest that this MIT is simple and will be proved to be useful in predicting the acute rejection as well as in controlling the immunosuppression.

Human adenovirus type 12 (Ad 12) was inoculated through subtentorial route into inbred newborn mice (C3H/BifB/Ki), and sequential changes of the brain and tumor induction were examined by histological and immunofluorescent methods. Two days after virus inoculation, Ad 12 specific tumor antigen (fluorescent T-antigen) appeared in the cells of ependymal and subventricular matrix layers, choroid plexuses and leptomeninges in the subtentorial as well as the supratentorial brains. After 10 days, these fluorescent positive cells decreased gradually in number but still remained focally beneath the ependyma. Sixty days later, early tumor nodules were detected in the same regions in which remained the fluorescent cells. After 107 days, neurological signs and well-developed tumors were noted in 25 of 63 (30.1%) mice examined. In the cerebellum, both of T-antigens and tumors were limited around the IVth ventricle, but not in the granular layers. Histomorphologically, the tumors were of primitive neuroectodermal origin and consisted of the cells resembling immature matrix cells in the subventricular zone. These findings strongly suggest that the virus has a selective affinity to the remaining matrix cells, but not to cerebellar granular cells, at least, in newborn mice.

Heterokaryon formation and Rous sarcoma virus (RSV)-induction were studied by fusion of RSV-transformed human embryonic cells with chick embryo fibroblasts in the presence of lysolecithin. Heterokaryon formation was observed by autoradiography. RSV-induction was identified by focus formation, electron microscopy and density gradient centrifugation of 3H-uridine-labeled particles. The most effective concentration of lysolecithin for virus induction was 10 mug/10(6) cells/0.1 ml. Efficiency of lysolecithin in virus induction was not less than that of ultraviolet-inactivated Sendai virus (UV-HVJ).
