Abstract

The effects of intracerebroventricular (i.c.v.) administration of angiotensin II (AII) and atrial natriuretic polypeptide (ANP) on the plasma corticosterone level were studied in conscious, unrestrained rats. Although i.c.v. injection of ANP had no apparent effect on the basal plasma corticosterone level, it attenuated the plasma corticosterone increase induced by centrally injected AII dose-dependently. These results suggest that ANP in the brain is involved in the regulation of the hypothalamo-pituitary-adrenal axis.
