[Effect of estrogens on the lipid composition of the plasma membranes of the uterine cells in ovariectomized rats].

The effects of estradiol, estrone and estriol on lipid composition of plasma membranes of the ovariectomized rat uterus cells were studied. It was found that estrogens (10 micrograms/100 g weight) and estrone (25 micrograms/100 g) fail to produce statistically significant changes in lipid contents in plasma membranes. Estradiol and estriol (25 micrograms/100 g) were shown to increase phospholipid content in plasma membranes calculated for protein.
