ジャーナル フリーThe axillary apocrine swe a t glands of ten patients of osmidrosis axillae were examined before and after pilocarpine injection.
After pilocarpine injection the cytoplasmic p r o tuberance increases. Mitochondria decrease and the secretion granules increase after injection. The alkaline phosphatase activity of the cytoplasm somewhat increases after injection. Also the activity of the myoepithelium increases. At the base of gland cells, there are metachromatically, with thionin stainable substances, and these substances decrease after pilocarpine injection. The PAS positive substances in the gland cell decrease after pilocarpine injection. It is probably true, that the apocrine sweat gland is stimulated by the injection of pilocarpine.抄録全体を表示PDF形式でダウンロード (1958K) -

ジャーナル フリー1. Using male albino rats of a subline of the Wistar strain weighing around 200 g, a series of quantitative measurements on the mitotic activity in the thymolymphatic organs have been made, with the aim to make possible a calculation of the total number of lymphocytes produced by mitosis per day in the thymolymphatic system. Mitotic counts were performed after suspensions of cell nuclei had been prepared from the thymolymphatic organs according to the technique described in the preceding paper (Ito,1959).
2. Normal values of the mitotic index were found to be 1.13+0.06% in the thymus,0.79 ±0.06% in the mesenteric lymph n odes, and 0.75±0.06% in the other lymph nodes.
3. The total percentage of mitoses per day in different organs of the thymolymphatic system was estimated to be 22.23 ±0.77% in the thymus,7.85±0.37% in the mesenteric lymph nodes, and 6.65±0.26%in the other lymph nodes. These figures were obtained after repeating the same experiment with colchicine over 4 successive 6-hour periods so as to cover a total of 24 hours.
4. Using the data of Mon d en (1959a) on the total number of lymphocytes contained in the thymolymphatic organs, the average number of excess mitoses of lymphocytes in the whole thymolyphatic organs was calculated to be 432 x 106. This is 3.3 times as great as the number of total lymphocytes present in the circulating blood.
5. By a direct calculation from the figures obtained f o r the daily mitotic rate, the turnover time of the lymphocytes in each organ of the thymolymphatic system was estimated to be 4.5 days in the thymus,12.8 days in the mesenteric lymph nodes, and 15.0days in the other lymph nodes.
6. Besides, an indirect calculation of the turnover time was made from Hoffman's formula, assuming that the mitotic time of dividing cells in the thymolymphatic tissue is of 1-hour and of 30-minute duration.抄録全体を表示PDF形式でダウンロード (2140K) -

ジャーナル フリーThe gingiva and the hard palates of the human embryos from the fourth to the ninth foetal month were used as materials and the attachment between the epithelium and the lamina propria were studied. The materials were fixed in 10% formalin, embedded in paraffin. Six micra thick sections were made vertically and parallel to the surface of the mucous membrane. Masson's trichrome stain and Pap's silver impregnation were done.
In general the reticular fibers in t h e lamina propria mucosae of the embryo show the transitional form to the structure of the 'adult. The cytoplasmic processes of the basal cells of the epithelium were not observed. The boundary between the epithelium and the lamina propria mucosae shows an almost straight line, and the reticular fibers in the boundary between the epithelium and the lamina pkopria run parallel or wavy to the basal surface of the epithelium. The penetration of the reticular fibers into the epithelium is not yet observed. With the increase of foetal months, the cytoplasmic processes of the basal cell penetrate into the lamina propria, and the reticular fibers of the lamina propria protrude into the epithelium, and both of these fit together. This structure can be observed imcompletely after the seventh foetal month. The fibers which protrude into the epithelium end blind. In general the development of the papillae and the reticular fibers of the lamina propria in the hard palate is more conspicuous than that in the gingiva. No histological difference is observed in the gingiva of the maxilla and that of the mandibula.抄録全体を表示PDF形式でダウンロード (2811K)
