[Histofunctional state of mouse ovaries in normal conditions and during hypervitaminosis A].
Morphometry was used to analyze different histofunctional structures of mouse ovaries (follicles of varying maturation grades, yellow and atretic bodies, interstitial tissue) in health and hypervitaminosis A (80 000 IU). It was noticed that in the ovaries of female mice in health, there occurred consistent cyclic processes marked by the changes in the number and size of the morphofunctional structures during different stages of the estrous cycle. In hypervitaminosis A, female mice had no estrous cycle. The ovaries showed the impairment of the growth of the follicles and enhancement of atresia. As a result, the follicles did not reach the final stages of development, which led to the cessation of ovulation and formation of yellow bodies.
