JOURNAL FREE ACCESS1) On the type of the 'ga n glion cervicalis uteri of the rats and mice, Forma-compacta which was classified by Blotevogel, predominates in general, but the type belonging to Farma-disserninata is seen too.
2) It is supposed that the vacuoles in the ganglion cells of the ganglion cervicalis uteri of the rats and mice have something to do with the secretory phenomena of the nerve cells. Namely, the vacuoles are not considered as a degenerative phenomena.
3) In the ganglion cells of the ganglion cervicalis uteri of the rats and mice, the vacuoles are increased at the pregnancy period and at the time of given follicle hormone injection, while they are decreased in the castrated animals, and there are none in the young animals. Accordingly it is thought, that the vacuoles have some relationship with the sexual activity, especially with the ovary.View full abstractDownload PDF (3486K) -

JOURNAL FREE ACCESSMore than 130 rats inclu d ing normal controls was used for studying the histology of the thyroid gland after partial thyroidectomy, with special reference to its regeneration. Partial thyroidectomy was performed by removal of one-third of the left lobe at 50 days of age (first group), and in the same way at 170 days and 300 days of age (second group) and by removal of the left lobe and isthmus at 50 days (third group). Long-term observation was tried only in the first group.
1. Partial re m oval induces regeneration of follicle cells and follicles in the remaining part. Regeneration of the follicle cells occurs by mitotic division, and not by amitotic division. The division occurs most frequently at three to 4 days after operation, ranking in frequency first in an injured area of the operated lobe, next in order in an non-injured area of the operated lobe and in the non-operated lobe. The frequency of mitotic division depends upon the age of animals, and division is more frequent in younger anima/s.
2. Regeneration of follicles occurs less frequently than might be expected, and chiefly occurs from,1. surviving cell cords and conglomerates originating from destroyed follicles in an injured area, and 2. from buds of follicles in other areas and continues to approximately 7 days after operation. No other modes of -regeneration of follicles by fusion and division of follicles, by re-arrangement of follicle cells broken up and by forming As c h of f's proliferative Regeneration of Thyroid Gland 227buds and S a n d e r so n's bolster-like swellings in the follicle walls are found.
3. The problem of regeneration of follicles from parafollicular cells remains undetermined. Cysts and their extending cell cords of ultimobranchial origin indicated no sign of production of follicles.
4. Partial removal soon induces transient increased activ i t y in the remaining part of the gland, indicated by various signs such as irregular change of follicles, swelling and height-increase of follicle cells with the formation of colloid droplets, feeble staining, dilution and reduction of colloid, and marked engorgement of capillaries.
5. This histological picture depends in intensity i n direct proportion to the extent of removal of the gland, and is more conspicuous by removal of the left lobe and isthmus than by removal of one-third of the left lobe. On the other hand, radioiodine is contained in inverse proportion to the extent of removal and the turnover and excretion of iodine may occur more rapidly by a greater extent of removal.View full abstractDownload PDF (3949K) -
VII. On the ramification of A. lingualis and its fine distribution in some mammalsHakuro Okano1960 Volume 34 Issue 3 Pages 233-279_14

JOURNAL FREE ACCESSDescriptions on the lingual artery achieved so far in literature are summerized as follows: 1) ramifications of the lingual artery and distributing appearances in perilingual tissues,2) distributions of finer blood vessels within the dorsal mucosa of the tongue as well as the lingual papillae,3) arteriovenous anastomoses within the tongue. The indian ink has been chiefly used for injection, and recently neoprene latex has come into use. But the acrylic resin is not yet employed. The present author is the first to observe cubically on branches of the lingual artery including thick vesseles as far as the fine, comparing them on each animal, and now takes an opportunity to discuss on each item with results by the seniors.View full abstractDownload PDF (17150K)
