[Hormonal function of the ovaries in women with breast hyperplasia].

In females showing fibrous-cystic mastopathy and fibroadenomatosis of mammary glands a specific form of progesterone insufficiency- relative one, was revealed, a high persistantly maintained level of urine pregnandiol and blood progesterone in a luteal phase (indicating a high hormonal activity of the corpus luteum) being observed. But luteal transformations were insignificant both in endometrium and vaginal epithelium, a moderate hypoestrogenemia being noted in the first phase and increased estrogen excretion- in the second phase of the cycle.

[Change in the RNA content in the rat endometrium under the action of estrogen-megestrol and neurotropic substances].

The effect of the hormone-like estrogen-progestagen preparation megestranol and of megestranol-spasmolytin combination on the activity of metabolic processes in the uterine mucous membrane was studied in experiments on rats. Results of cytochemical studies showed megestranol and megestranol-spasmolytin combination to change the metabolic activity of the uterine mucous membrane resulting in a decrease in the RNA content in the epithelial cells of the endometrial glands, thereby creating conditions preventing normal implantation and development of the fertilized ovum.
