1 Effect of beta-blocking agents and angiotensin II on isoproterenol-stimulated renin release from rat kidney slices. Isoproterenol renin Rattus norvegicus
2 We previously demonstrated that renin release by kidney slices may be increased by beta-adrenergic agonists, and the present communication contains our results on the effects of 15 beta-blocking agents and angiotensin II on isoproterenol-stimulated renin release. Isoproterenol renin Rattus norvegicus
3 We previously demonstrated that renin release by kidney slices may be increased by beta-adrenergic agonists, and the present communication contains our results on the effects of 15 beta-blocking agents and angiotensin II on isoproterenol-stimulated renin release.

4 (3) Dose-related inhibition was observed with practolol, oxprenolol, timolol, nadolol, and atenolol at concentrations ranging from 10-8 to 10-5 m. Basal renin release was significantly (P is less than 0.01) inhibited by angiotensin II at 10-6 m, which also inhibited isoproterenol-stimulated renin release in a dose-related fashion. Isoproterenol renin Rattus norvegicus
5 CONCLUSIONS: There are three different effects of beta-blocking agents on isoproterenol-stimulated renin release which can only partially be explained by their presently ascribed pharmacological properties. Isoproterenol renin Rattus norvegicus
