摘要: Abstract Although exogenous angiotensin is recognized as a potent dipsogen, the participation of endogenous in thirst has not been well established. To investigate this question, we produced rats by relative cellular dehydration (hypertonic NaCl injection), or hypovolemia (hyperoncotic polyethylene glycol injection). An receptor antagonists (sar(1)-ala(8)- II, P-113), converting enzyme inhibitor (SQ, 20, 881, SQ) given to thirsty intracerebroventricular (IVT) peripheral routes. P-113 infused i.v. (10 μg/kg/min) injected IVT μg) did alter drinking response either stimulus. The latter treatment reduced 50 ng II (p
