title: Effects of atrial natriuretic peptide on phenylephrine-induced renin release in dogs.
abstract: 1. The effect of atrial natriuretic peptide (ANP) on alpha-adrenoceptor agonist-induced renin release was examined in the de-ennervated kidney of the anaesthetized dog pretreated with propranolol (1 mg/kg, intravenous). 2. Phenylephrine (50 ng/kg per min) infused into the renal artery increased the renal secretion rate of renin (RSR) without affecting systemic blood pressure or renal blood flow. 3. Although basal RSR was unaffected, the phenylephrine-induced increase in RSR was abolished during intrarenal arterial infusion of ANP (10 ng/kg per min). 4. The results suggests that exogenously administered ANP could suppress alpha-adrenoceptor-mediated renin release in the dog.
