JOURNAL FREE ACCESS1. The influence of ninh y drin on the activity of the alkaline phosphatase was examined.
2. In the inje c tion method, remarkable decrease of the activities are noticed chiefly in the central region of the liver sections aft the 30 minutes cases after the injection of the aqueous solution of ninhydrin. In the kidney sections, the decrease of the activity of the enzyme is recognized into the epithelial cells of the distal convoluted tubules in the 30 minutes cases after the injection, in the glomeruli, in the one hour case, and in the epithelial cells of the proximal convoluted tubules, in the six hours cases.
3. M the results of the method in which the sections are stained after they are exposed to the solution of the drugs directly, the activities in the liver and kidney sections disappear after they are incubated in the 1% aqueous solutions of ninhydrin for 30 minutes at 37°C.
4. As the method in which the sections are stained after they are treated with the mixture of the substrate solution and the solution of the drug, the activities of the liver and kidney sections and undemonstrable when the sections are stained after they are incubated in the mixture of the substrate solution and 5 cc of the 1% aqueous solution of ninhydrin.
We should like to record our thanks to Prof. Dr. T. Taniguchi for his helpful guidante and criticism.View full abstractDownload PDF (779K) -

JOURNAL FREE ACCESSDifferentiation of the spermatids ofMus molossinus TemmincketSchlegel has been described from a study of electron microscopy of thin sections of testis. The head cap and acrosome develop from the Golgi complex. The development of the caudal sheath from the outer layer of the nuclear membrane takes place in the same manner as in albino rat spermatogenesis.
The caudal sheath has played a role in separating mitochondria during the formation of the tail axial fibrils.
During maturation of the spermatid the karyoplasm undergoes striking physicochemical alterations. Both fine dense chromocenters and less dense coiled filaments at random dispersed in the karyoplasm are replaced by dense coiled filaments arranged parallel along the longitudinal axis of the spermatid nucleus.View full abstractDownload PDF (862K) -

JOURNAL FREE ACCESSThe author observed cytochemically the effect of the pilocarpine administration of the plantar sweat gland of the cat, comparing the results obtained in the cases with and without the pilocarpine injection, by applying the detecting procedures for acid phosphatase, alkaline phosphatase, protein and glycogen and the iron-hematoxylin technique.
The presence of the cells of the two different types, the superficial and the basal cells, which was described by Ito and his collaborator on the human eccrine sweat glands, has been ascertained cytochemically by the author also on the cat eccrine sweat glands. These cells can be distinguished cytochemically by the difference of the intensities of the acid phosphatase activity. The differentiation of these cells from each other is not appreciably distinct by the alkaline phosphatase technique, and it is impossible by the protein and the glycogen stain procedures.
After the administration of pilocarpine by injection, the most distinct changes are seen in the alkaline phosphatase activity and the glycogen contents, and the acid phosphatase activity and the stain reaction by the iron-hematoxylin technique change moderately. Generally these changes are remarkable in the basal cells.
From. these findings the author concludes that the basal cells have also a secretory function as well as the superficial cells, and play a certain roll in the perspiration caused by the pilocarpine injection.
The stainability of protein, is not influenced by the pilocarpine perspiration, showing no change in the cytomorphological features.View full abstractDownload PDF (2248K)
