Abstract

The role of atrial natriuretic peptide (ANP) in the ACTH response to stress and the glucocorticoid negative feedback control of ACTH release was investigated in adult male homozygous Brattleboro and adrenalectomized Wistar rats respectively, using the technique of immunoneutralization. The relatively low ACTH response to stress and the lack of arginine vasopressin make the homozygous Brattleboro rat a more rigorous and simpler preparation in which to test the hypothesis that ANP is involved in the ACTH response to stress. In both sets of experiments, blood sampling and injection of sheep anti-ANP or control serum were carried out in conscious animals through intra-atrial cannulae implanted 2..
