Abstract

Morphogenetic and histogenetic changes in the ovaries of Citellus citellus during the postnatal period and hibernation (September- March) at the age of 10, 25, 45 days and 2 to 12 months after birth were studied. Significant cellular and tissue-organoid differentiation processes were established. After birth oogonia enter the prophase I of meiotic division. At the end of the first month, oocytes with enlarged cytoplasm and single layer of satellite cells form the primary follicles. The growing follicles with organizing antrum are formed in the third postnatal month. During the same time, theca foliculi is observed. Between the 3d and the 6th months after birth the authors demonstrate a "stage ox isofolliculia" when the follicles stop undergoing further development. During the winter hibernation, the ovarian follicles continue to grow slowly and at the end of this period, preovulatory follicles are formed. The results reported demonstrate Citellus citellus ovary to be an organ of intensive cell-tissue reconstruction during the postnatal development and hibernation period determined by the ovarian histophysiology, the ovarian steroid hormones production and the hormonal activity of other glands and organs of the endocrine system.

摘要

研究了出生后10天、25天、45天以及出生后2至12个月处于冬眠期(9月至次年3月)的黄鼠卵巢的形态发生和组织发生变化。确定了显著的细胞和组织类器官分化过程。出生后,卵原细胞进入减数分裂前期I。在第一个月末,细胞质增大且有单层卫星细胞的卵母细胞形成初级卵泡。出生后第三个月形成带有组织化卵泡腔的生长卵泡。同时,观察到卵泡膜。在出生后第3至6个月间,作者观察到一个“等卵泡期”,此时卵泡停止进一步发育。在冬季冬眠期间,卵巢卵泡继续缓慢生长,在此阶段结束时,形成排卵前卵泡。所报道的结果表明,黄鼠卵巢是一个在出生后发育和冬眠期进行密集细胞 - 组织重建的器官,这一过程由卵巢组织生理学、卵巢甾体激素产生以及内分泌系统其他腺体和器官的激素活性所决定。
