    Regional cerebral blood flow was simultaneously measured in six regions of 4 normal subjects and 13 patients with apoplexy in subacute and chronic stages by 133Xe clearance method. The average values of mean cerebral blood flow of the six regions, the flow of fast and slow components and the relative weight ratio of the fast component in normal subjects were 46.9ml/100g/min, 73.7ml/100g/min, 22.1ml/100g/min and 49%, respectively. The patients were divided into two groups: one group of 9 patients without cerebral arterial occlusion on the carotid angiogram and the other group of 4 patients with the middle cerebral artery occlusion. In both groups, the cerebral blood flow was decreased, especially in the group with the middle cerebral artery occlusion. Abnormal foci, where interregional differences exceeded 14%, were observed in 6 out of 9 patients without arterial occlusion and in 3 out of 4 patients with the middle cerebral artery occlusion. In the former, such abnormal foci did not coincide in all cases except one with the diseased regions which were assumed from neurological findings. However, in the latter, ischemic regions were almost restricted to the territory of the middle cerebral artery.

    Three cases of atypical pneumonia with pleural effusion were reported. Two cases were siblings. There was no evidence for tuberculosis or bacterial infection in these cases. There was a significant rise of complement-fixing (CF) antibody titer to Mycoplasma pneumoniae (M. pneumoniae) in the three cases. M. pneumoniae was isolated from the pleural fluid of a case. CF antibody was demonstrated in the pleural fluid in two cases. Skin rashes were found in two cases during course of illness.

    The dermatoglyphic analyses in 10 Japanese patients with Rubinstein-Taybi syndrome were made in comparison with those of 571 control individuals. It appeared that these patients showed characteristic configurations of patterns on the thenar/first interdigital area, patterns in the hypothenar area and simian creases. There appears to be little difference in Rubinstein-Taybi syndrome between Japanese and Caucasian patients.

    The latest techniques in scanning electron microscopy have been applied to this study. In cholesterol gallstones, the fracture surface generally shows a crystalline plane radiating pattern, often showing dendritic growth, around the nucleus. On the surface or fracture plane of a cholesterol stone, parallelogram crystals or corrugated crystals are sometimes seen. In higher magnification, the surface of a crystalline plane is seen to be composed of lamellae of about 200 A in thickness, which is frequently associated with spiral growth. In view of the fact that a number of linear boundaries are just visible near the center of each spherulite, it appears that, in the multinuclear stones, cyrstallization starts at various points or nuclei and spreads out from these points. These results support the view that cholesterol crystals proceed from the center toward the periphery.

    A series of experiments was carried out to clarify the significance and indication of pyloromyotomy or pyloroplasty as a drainage operation obtaining the following results. Pyloromyotomy suppresses the state of abnormal excitation of the pyloric portion, resulting in the decrease of contraction pressure of the pylorus, when an incision is done long enough. Pyloroplasty after Heineke-Mikulicz, however, is more effective as a drainage operation. The fundamental significance of pyloromyotomy seems to be in reducing the contractile force of the circular muscle at the pyloric region maintaining the sphincteric function. And that of pyloroplasty is in its effect in sacrificing the sphincteric function of the pylorus and in widening its lumen to result in a greater drainage effect. Thus, pyloroplasty is indicated when severe excitation of the remaining pyloric portion is present and the powerful drainage effect is desired even sacrificing the sphincteric function of the pylorus. On the other hand, pyloromyotomy has an indication when the less drainage effect seems sufficient and preservation of the sphincteric function of the pylorus is needed.

    Zur morphologischen Oberflächenbetrachtung der Sinnesepithelien des Vestibularapparates wurde die Silberfärbung and Succinodehydrogenasereaktion erfolgreich angewandt.
    1) In der Mitte der Crista ampullaris werden oft grössere Sinneszellen gefunden, während an der Peripherie kleinere Zellen angeordnet sind. Die Zelldichte ist an der Peripherie grösser als im Zentrum.
    2) Die Striola setzt sich zu zwei Drittel aus Zellen des Typ I zusammen, während ausserhalb der Striola 45% dem Typ I angehören. Mit 55% aller Sinneszellen ist der Typ II beteiligt.
    3) Die groβen Sinneszellen des Typ I, die man in der Striola antrifft, werden gewöhnlich vom gemeinsamen Nervenkelch innerviert.
    4) Die groβen Sinneszellen der Striola enthalten mehr Succino-dehydroge-naseaktivität als die anderen kleineren, randständigen Zellen der Macula.
    Für herzliche Hilfe bei der Druchführung der Arbeit and für die Übersetzung danken wir bestens Fräulein Otgert Bull.

    The discharge of testicular ascorbic acid into spermatic venous blood was examined in intact and methylenedianiline-treated dogs. An intravenous injection of human chorionic gonadotrophin (HCG, 20iu or 40iu/kg) to intact dogs produced a marked increase in the discharge of ascorbic acid as well as in the secretion of 17-oxosteroids from the testis within 15 minutes after the injection. However, neither of these events occurred when methylenedianiline (20mg or 60mg/kg) was given beforehand, while the administration of methylenedianiline (60mg/kg) after HCG (40iu/kg) had been injected failed to abolish an increased discharge of ascorbic acid induced by HCG, although it brought about a substantial inhibition of the increased secretion of testicular 17-oxosteroids. From these results, it is suggested that HCG markedly stimulates the discharge of testicular ascorbic acid, and ascorbic acid in the testicular tissue is closely linked with biosynthetic mechanism of androgens.

    Adrenal biopsy was carried out at the time of operations for renal diseases and the histological findings in 62 cases were studied with systemic biochemical laboratory examinations. Adrenalitis prevalent in infected renal diseases as a probable sequence of contiguous involvement had apparently no direct relation to the level of urinary 17-OHCS. Hyperplasia of the adult glomerulosa was high in incidence in cases with hypertension and/or low levels of serum potassium. Outward transformation of fasciculata cells was prevalent in cases with high levels of NPN, hypertension and/or abnormal levels of serum potassium. Inward transformation of fasciculata cells was closely related with elevated levels of urinary 17-OHCS and 17-KS. This lesion as well as hyperplasia of the reticularis was frequently associated with low A/G ratios.

    Effect of tissue fixation for the histochemical identification of individual acid mucopolysaccharides was investigated by the application of the critical electrolyte concentration concept. Materials used were cock's comb, the femur-tibial joint and costal cartilage of rat, and human umbilical cords. As fixatives, neutral formalin, CPC-formalin and Carney's fluid were employed. Model experiments were performed with pure acid mucopolysaccharides. The pattern of the critical electrolyte concentration of each acid mucopolysaccharide in the non-fixed sections bore a close parallel to that in the model experiments. However, there was difference between the non-fixed and the fixed sections concerning the critical electrolyte concentration of each acid mucopolysaccharide. After peptic digestion, the pattern of the critical electrolyte concentration in the fixed sections was similar to that in the non-fixed sections.

    The specific elution method has been used for investigating the presence and quantitation of blood group antigens on the surface of HeLa and S3 cells. S3 cells which had been cultivated independently in various laboratories constantly exhibited B blood group antigenicity, but wild HeLa cells, represented H antigenicity. Each of the cells contained M blood group antigen, but not N antigen. Possible mechanisms of the conversion of the antigen from H to B in S3 cells were discussed.

    An apparatus for automatic recording of dose distribution in moving-field radiotherapy was devised. Ionization current output from the ionization chamber inserted in the human phantom made of acrylite was amplified and converted into voltage by the direct current amplifier. Output from the direct current amplifier of each channel was integrated in the integrator, which was put into the divider. Relative dose value thus obtained were typewritten in the corresponding points on the recording paper automatically through the A-D convertor. Actual examples of dose distribution by this method are illustrated.
