Abstract

The authors studied the role of brain angiotensin II in subfornical organ-pressor responses using urethane-anesthetized, tubocurarine-immobilized rats, and the present work obtained the following finding: angiotensin II (AII) induced pressor responses by injection into several brain regions: either subfornical organ (SFO), nucleus paraventricularis (NPV) or its projection areas, including rostral ventrolateral medulla (RVLM), periaqueductal gray matter (PAG) and locus coeruleus (LC).

Key words: Angiotensin Ⅱ;Pressor response;Subfornical organ;Nucleus paraventricularis;Periaqueductal gray matter;Locus coeruleus
