JOURNAL FREE ACCESSThe author used the subm a xillary glands of mice which stimulated the secretion of saliva by the subcutaneous injection of pilocarpine. And changes with the lapse of time after injection were observed cytologically and histo- and cytochemically, the following results were obtained.
1. The terminal portion of the submaxillary glands of mice is divided into the glands consisting of clear cells and those consisting of dark cells. In the process of the secretion of the clear cells, stainable granules are observed, but in the dark cells the stainable granules are not observed.
2. On the changes in polysaccharide by PAS staining, PAS positive substance in the cytoplasm, the basement membrane and other tissues decrease throughout from the beginning of the secretion to the end.
3. Alkaline phosphatase is very intense in its activity in the basement membrane and in the capillaries. The activity in the cytoplasm is temporarily strengthened immediately after the onset of secretion but it becomes weak with the lapse of time. The activity in the capillaries is almost constant.
4. The activity i n acid phosphatase is more intense in the cytoplasm of the clear cells than in that of the dark cells. Besides, the activity in the apical portion of the cell is more intense than that in the base. Though generally the activity in acid phosphatase is temporarily strengthened immediately after the onset of the secretion and it gradually becomes weak with the lapse of time, the activity of the nucleus becomes hardly low.
5. A lot of RNA is contained in the cytoplasm of the glandular cells, and its variety in quantity is about the same as the formation of the stainable granules in protein staining. This fact shows that RNA has to do with the synthesis of protein.
The author wishes to express his sincere thanks to Prof. T. Taniguchi for his criticism. This study was performed under the project of Instructor M. Jhnuma.View full abstractDownload PDF (4831K) -

JOURNAL FREE ACCESSIn a series of adult albino rabbits, the common carotid artery was tied by two ligatures about 10-15 mm apart. After 4,8,12 and 16 days, cellular elements or fragments of bone marrow and those of lmyph node of the same animal were injected into the double-ligate d segment of the artery. It was disclosed that neither the immature blood cell of bone marrow nor the lymphoid cells of lymph node injected into the ligated artery showed any tendency toward growth therein. In contrast, the endothelial cells in the enclosed segment of the artery were in active proliferation from the 7th day on after ligature.View full abstractDownload PDF (1195K) -

JOURNAL FREE ACCESSThree groups of prepuberal, young adult and old mice in our colony originating from a Japanese mixed albino strain were injected once with 100 I.U. of mare gonadotropic hormone and soon after or a few days after injection were mated. In the former two groups, impregnation occurred immediately or some days or weeks after treatment. A tendency towards superfecundity and a high mortality of the fetuses were recognized in the mice of those groups, which conceived shortly after injection. Furthermore, the occasional occurrence of various skeletal malformations in the extremities, spinal column and palate were recognized in the fetuses of the treated prepuberal, and young adult mice. These anomalies were most often found in prepuberal cases. The length of the interval between the day of hormone injection and that of conception, seems to have no influence upon the frequency of malformations. As a mechanism for producing these malformations, effects of hormone, young maternal age and superfecundity were considered. When this hormone was given to old mice showing no oestrus cycle, pregnancy occurred in only one case, but the fetuses on it were found to be dead at midpregnancy.View full abstractDownload PDF (1253K) -

JOURNAL FREE ACCESS1) In the sciatic nerve of toads, the greater the diameter of nerve fibers, the more the number of incisures in 1000μ,. The correlation coefficient is+0.44 (significant level 0.1 % ). Its regression line y is 1.87x+17.1.
2) T he greater the diameter of a fiber, the longer the internodal length. The correlation coefficient is 0.75 (significant level 0.1 %). Its regression line y is 185x-165
.3) The greater the diameter of a nerve fiber, the more the number of incisures in a myelin segment. The correlation ratio is 0.975. The curved line E is 8.71×1.17x
4) There is no regularity in th e arrangement of incisures.
5) When fixing solution is added incisures are o p ened, but the number of incisures shows no increase or decrease. The opened incisures do not recover to their former form.

JOURNAL FREE ACCESSThe Gil. vestibulares nasi of cats were observed cytologically and cytochemically before and after adrenalin injection. The vacuoles, which have no stainability with iron hematoxylin and exist in the luminal cytoplasm in the control case, decrease in the five minutes case and then increase in the twenty minutes case after injection.
The PAS positive, coarse granules, appear in the luminal cytoplasm in the five minutes case after injection as compared with the control. In the twenty minutes case above mentioned granules disappear.
The alkaline phosphatase activity in the luminal cytoplasm increases in the five minutes case after injection as compared with the control. In the twenty minutes case after injection the activity of the terminal extension of the cytoplasm is the strongest.
No difference of the activity o f acid phosphatase is observed before and after pilocarpine injection.
In the five minutes case after injection the stainability of nucleoli with thionin increases and the pigment granules with capsules of RNA appear in the luminal cytoplasm. In the twenty minutes case, after injection, the stainability of the side of and above the nucleus increases. In the five minutes case, after injection, the stainability b y the Hg-BPB method in the base of cells increases. In the twenty minutes case, after injection, the stainability of the myoepithelium increases.
