title: [Effects of adrenal medullectomy and passive immunization with an anti-CRF antiserum on the corticotropin secretion in response to stress in Long-Evans rats].
abstract: Ether stress-induced ACTH and corticosterone secretion is similar in 60 days adrenal medullectomized and intact Long-Evans Rats. Passive immunisation with a 41-CRF antiserum impairs corticotropic function after stress. This decrease is more pronounced in adrenal medullectomized than in intact animals. These results suggest that epinephrine plays a minor role on the stress induced ACTH secretion. This role can be demonstrated only after immunoneutralisation of endogenous 41-CRF.
