| Abstract: | E ects of prolactin (PRL), bromocriptine (Br), testosterone propionate (TP), dihydrotestosterone (DHT) and the combinations of these androgens with PRL/Br on specific activities of adenosine triphosphatases (ATPases) of seminal vesicles and cranial and caudal prostates were studied in castrated adult bonnet monkeys. Castration decreased all ATPases (sodium/potassium, magnesium and calcium dependent) of seminal vesicles and both the lobes of prostate. PRL restored the normal activities of all ATPases in both the organs. Br given alone decreased all ATPases of prostate but caused no significant alteration, particularly calcium dependent ATPases of seminal vesicles and caudal prostate. TP/DHT replacement restored all ATPases of both the organs to the normal levels. PRL + TP/DHT further enhanced all the ATPases activities of all the regions studied. Br + TP/DHT decreased all ATPases but it did not produce any alteration in the calcium ATPases of seminal vesicles. The results suggest that prolactin facilitates membrane transport enzymes in the cranial and caudal prostate and seminal vesicles of adult castrated bonnet monkeys. |
