title: Uptake in vivo of 45Ca in male accessory sex organs of the rat: effect of estramustine phosphate and diethylstilbestrol diphosphate.
abstract: The radioactivity following a single i.v. injection of 45Ca into male rats was found to be significantly higher in seminal vesicles, dorsolateral prostate, coagulating glands and ventral prostate than in muscle. The acute effect of a single dose given intraperitoneally of estramustine phosphate (Estracyt) and diethylstilbestrol diphosphate (Honvan) were examined on 45Ca uptake. Generally, the 45Ca concentration in the accessory sex organs with the exception of the dorsolateral prostate increased after administration of estramustine phosphate. Diethylstilbestrol phosphate treatment also significantly increased 45Ca uptake in the ventral prostate when measured on the basis of tissue wet weight but not on the basis of protein. The implications of these findings are discussed in relation to the therapeutic action of Estracyt in prostatic carcinoma.
