    Electromyographic effects of intravenous administration and hypothalamic implantation of cinchophen on the gastric motor activities were studied in the mongrel dogs. Intravenous administration of cinchophen sodium in both doses of 100 mg and 300 mg per kg of body weight induced the prolongation of the intervals of spike potentials in the first 5 minutes. In the next 5 minutes, only by 300 mg/kg administration, the intervals were prolongated. Then in the third 5 minutes, action of cinchophen on the gastric motor activities ceased in both cases. The degree of prolongation aftcr administration in a dose of 300 mg/kg was greater than that ot 100 mg/kg.
    A consistent prolongation in the intervals of spike potentials was observed following only middle hypothalamic implantation of 1 mg cinchophen sodium. Median eminence implants, however, failed the prolongation of the intervals of spike potentials.
    These findings suggest that cinchophen reduced the gastric motor activities through the direct action upon the middle hypothalamus.

    On the charging of the skin or wearing clothes produced by the body motion was reported previously by the author. In this paper the charging of the body due to contact of the hand of the subject to the clothes of another person was reported.
    The method used in this experiment was almost the same as the one previously reported. An electrode was clasped in the left hand of the subject and the other one was connected to the earth. The subject stood on the earth putting on different kind of clogs. The charging of the body of the subject when he contacted with his right hand to the wearing clothes of the other person was recorded. The results were the following :
    1) The amplitude of the charging was different according to the kind of cloths of the wear, it was large when the cloth was made of chemical fiber.
    2) The amplitude of the changing was also different when intensity and rapidity of the contact was different, the more intense and rapider was the contact, the larger the amplitude.
    3) When the footclogs of the subject differed, the changing was different. In case of footclogs made of rubber the amplitude of the charging was the largest.

    With the object elucidating the fusion mechanism of the rats secondary palate, the following experiments were performed with rat embryos of 15 days 12 hours and 16 days 12 hours of age.
    1) Pairs of 15-day 12-hour embryos, separated from the neighbouring tissue were placed side by side to be incubated at 72 hours and 96 hours.
    2) Pairs of lateral palatal shelves of 15-day 12-hour embryo, with a portion of the basis cranii attached to each, were together incubated for 48 hours.
    3) Pairs of lateral palatal shelves of 16-day 12-hour embryo, with a portion of the basis cranii attached to each, were together incubated for 48 hours.
    4) Pairs of lateral shelves of 16-day 12-hour embryo with a foreign body-Milllpore Filter-inserted between each pair at an anterior 1/3, which had already been fused, were incubated for 72 hours to observe the development of the fusion.
    5) Pairs of lateral palatal shelves of 15-day 12-hour embryo, with each two parts shifted one another along the the median lines, were incubated for 72 hours and 96 hours.
    and the fusion processes in these experiments were histologically observed with the following results.
    a) In experiment 1, mesenchymal transmigration occured in all length of lateral palatal shelves.
    b) In experiments 2 and 3, epithelial fusion was confirmed to progress continuously both anteriorly and posteriorly frcm the point of the primary joining, accompanied by stratification of epithelial cells.
    c) In experiment 4, mesnchymal transmigration occurred except in the part where the contact of the two lateral palatal shelves was prevented by the insertion of a Millipore Filter. Then in experiments 3 and 4, even when continuous joining of lateral palatal shelves was inhibited, fusion took place at the posterior end.
    d) In experiment 5, mesenchymal transmigration occurred despite the horizontal shift of the two shelves on the surface of contact.
    f) From these results, the fusion mechanism of the lateral shelves of the rat embryo can be suggested a concrescence.
    g) In the end, a clinical case of the secondary palate showing a particular morphology of median fissure was examined, and its genesis was discussed.

    Fusion potentiality at the medial margin of the lateral palatal process and the nasal septum was investigated by organ culture. The material was obtained from Wistar rat foetuses of 15-days of gestation. The lateral palatal processes, nasal septa and tongues were cultivated in vitro before histological examination. The cultured materials were fixed in Zenker-formalin and Bouin's fixative, and embeded in paraffin. Stainings of these sections were in hematoxylin-eosin, Mallory's triple staining and PAS reaction.
    The results revealed the following facts.
    1) The types of the fusion in the resulting palatal processes were divided into the mesenchymal transmigration (complete fusion), epithelial fusion and no fusion.
    2) Mesenchymal transmigration was obtained between the both lateral palatal processes when the medial margins of them were apposed, after 72-hours incubation.
    3) Epithelial fusion was obtained when the lateral palatal processes were setted in cross position, and the medial margin of one lateral palatal process was in contract with an area other than the medial margin of the other lateral palatal process.
    4) Mesenchymal transmigration was obtained between the medial margin of lateral palatal process and lower part of the nasal septum after 72-hour incubation.
    5) Mesenchymal transmigration was obtained between the both of the lower parts of the nasal septa of the littermate embroys after 72-hours incubation.
    6) Epithelial fusion was obtained between the medial margin of the lateal palatral process and lateral margine of the tongue after 72-hours incubation.
    The following conclusions were drawn from the above that :
    In the secondary palatal formation of the rat embryos the medial margins of the lateral palatal processes have specific potentiality of fuston.
    The lower part of the nasal septum also have potential for fusion.

    1) Two cases of lymphoreticular hyperplasia of the stomach were reported. They were diagnosed as malignant ulcer of the stomach by preoperative radiologic and gastrofiberscopic examination, and were treated surgically with partial gastrectomy of Billroth 1 type.
    2) In both cases, radiological characteristic finding of the stomach showed wide filling-defect with multiple ulcers in part of the stmach body, which finding was resembled to gastric carcinoma.
    3) Macroscopic finding of the resected stomach showed that diffuse, granular or giant encephaloid hyphertrophy of mucous membrane, which surrounded gastric ulcer situated on center of it, and combined multiple erosions.
    4) Patho-histological findings showed that proliferation of the lymphoid tissues locating in the mucous membrane and submucosa around the chronic gastric, ulcer, and simultaneously infiltration of many kinds of inflammtory cells, and then there were none atypicality in structural cells of lymphoid tissues. Above those findings agreed with lymphoreticular hyperplasia.
    5) Preoperative diagnosis of this disease was possible to some extent by radiologic examinasion, but we thought that the most excellent diagnostic procedure was biopsy of the mucous membrane.
    6) Patho-histological differerential diagnosis of this disease from malignant lymphoma or giant follicular lymphoma was importance, those leasions were rare in the stomach, but exhibited the most resembling patho-histological findings.
    7) Commonly, lymphoreticular hyperplasia of the stomach was thought the benign lesion, but pathogeneses of this disease have not yet to be delineated completely, we think that operative treatment of this leasion is better procedure than the others.
