Abstract
Effects of four doses (0.1, 0.2, 1.0 and 2.0 nmol/kg) of brain natriuretic peptide (BNP) on natriuresis and blood pressure were investigated in anesthetized spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY). An intravenous injection of 1.0 and 2.0 nmol/kg of BNP caused a significant increase of natriuresis and reduction of blood pressure in SHR and WKY. These effects were essentially identical to the effects of atrial natriuretic peptide (ANP). Remarkable bioactivity elicited by BNP rasises the possibility that BNP has a role in the regulation of blood pressure and water-electrolyte balance. On the other hand, when the effects of BNP on both strains of rats were compared with those of alpha-human ANP reported previously, the hypotensive effect of BNP was less than those of alpha-human ANP only in SHR. It is suggested that BNP might have different bioactivity than that of ANP in SHR.Entities:
