title: beta-Adrenergic receptor manipulation and acid phosphatase and zinc levels in the ventral prostate of the adult rat.
abstract: The influence of 15-day treatments with the beta-adrenergic receptor agonist isoproterenol (120 micrograms/kg/d) or the antagonist propranolol (1.00 mg/kg/d) on acid phosphatase and zinc levels in the ventral prostate was examined in intact rats, rats simultaneously injected with dexamethasone (0.25 mg/kg/d) and animals chemically castrated with a single dose of ethane dimethanesulphonate (75 mg/kg). Isoproterenol-treatment significantly increased acid phosphatase concentration in the ventral prostate of intact rats, whereas propranolol prevented a glandular zinc loss induced by dexamethasone administration. These results demonstrate that the levels of both biochemical parameters in the prostate can be altered by beta-adrenergic receptor manipulation. The responsiveness of the two secretory processes is different and depends on the functional status of the ventral prostate.
