[The morphofunctional parallels in rat ovaries after 40-day hypokinesia]. / Morfofunktsional'nye paralleli v iaichnikakh krys posle 40-sutochnoi gipokinezii.

An effect of a 40-day hypokinesia produced by the stay of the white mongrel female rats in the small cages on their reproductive system was studied. The data being indicative of the involvement changes in the ovaries which appear as the decreased mass of an organ and qualitative alterations of its structures (depletion of germinate stroma, decrease in volumetric part of the follicles) have been obtained with the use of radioimmunologic technique, light-optical methods and quantitative analysis of tissue specimens. In this case, the yellow bodies become dominant structures in the ovary. A comparison of structural changes with progesterone and estradiol concentrations revealed a pronounced hormonal insufficiency of the follicles and yellow bodies.
