Abstract

The effect of intracerebroventricular (i.c.v.) injection of brain natriuretic peptide (BNP), a novel peptide purified from the porcine brain, on arginine vasopressin (AVP) secretion was studied in conscious, unrestrained rats and was compared with that of atrial natriuretic polypeptide (ANP). I.c.v. administration of BNP (0.01, 0.1 or 1 nmol) significantly inhibited basal AVP secretion and the effect of BNP was comparable to that of ANP. The AVP secretion induced by i.c.v. injection of angiotensin II (0.1 nmol) was significantly suppressed by the pretreatment with BNP (0.1 or 1 nmol). These results suggest that BNP is involved in the central control of AVP secretion either alone or in combination with brain ANP.
