abstract：:The effect of atrial natriuretic peptide (ANP) on renin release is controversial. Several reports state that ANP inhibits renin secretion, while others have shown no effect. We investigated the effect of synthetic rat ANP with 24 amino acids (atriopeptin III) on renin release in vitro in a dynamic superfusion system o...
