[The effects of testosterone and estradiol on the activity of lysosomal enzymes in rat liver and kidneys].

In in vitro tests with lysosomes isolated from the liver and kidneys of castrated rats of both sexes the action of testosterone and beta-estradiol in concentrations of 3.76.10(-4)M on the activity of beta-glucosidase, beta-galactosidase and acid phosphatase was investigated. Testosterone is shown to reduce the total and free activity of the membrane-bound enzymes and to increase the release from the matrix lysosomes. Estradiol proved less active than is testosteron. The renal lysosomes in vitro are more sensitive to the action of sex hormones than are hepatic lysosomes. In the interaction of testosterone and estradiol with lysosomal membranes a sex specificity was revealed.
