摘要：

An immunoneutralization technique with specific antibodies was used to explore the role of neuropeptide Y (NPY) in the adrenocorticotropic hormone (ACTH) release after hypoglycemic stress in the dog. Dogs received injections of rabbit antihuman NPY γ-globulin (anti-NPY) or normal γ-globulin (NGG) into the third cerebral ventricle, which was followed by i.v. injection of insulin. Hypoglycemia of a 40% fall in systemic glucose levels occurred in anti-NPY-treated dogs as well as NGG-treated animals. An intraventricular administration of anti-NPY significantly inhibited the ACTH and cortisol release to hypoglycemia, but had no effect on the pancreatic polypeptide (PP) response. These findings suggest involvement by endogenous NPY in the ACTH secretion induced by hypoglycemia. © 1990.
