Changes in the blood serum lipids and lipoproteins of rats in ovariectomy and to the administration of the methyl ester of 6-hydroxy-D-homo-8-isoestrone]

Ovariectomy of rats resulted in biphasic increase of the blood plasma cholesterol (on days 42-54, 70), the alteration of lipoprotein spectrum. The administration to ovariectomized rats of methyl ether 6-oxy-D-homo-8-isoestrone in a dose of 0.01 mg/kg brought about lowering of serum cholesterol and normalization of lipoproteins spectrum. The above trends were not observed after introduction of 0.01 mg/kg estradiol.
