    Abstract:
    The effect of synthetic atrial natriuretic peptide (ANP) was examined on the in vivo and in vitro release of ACTH. Intravenous ANP (4 micrograms/kg body weight) administration did not affect the corticotropin releasing factor (CRF, 4 micrograms/kg body weight)-, arginine vasopressin (AVP, 2 micrograms/kg body weight)- and angiotensin II (A II, 4 micrograms/kg body weight)-induced ACTH release in unanesthetized freely moving rats. ANP did not inhibit the basal, CRF- and AVP-induced release of ACTH in pituitary cell cultures. ANP did not affect the CRF- and AVP-induced plasma corticosterone elevation, while it attenuated the AVP-induced corticosterone elevation. These results indicate that ANP does not affect the ACTH release at the pituitary level in vivo and in vitro.
