to evaluate a central role of angiotensin in vasopressin ( adh ) release in response to hyperosmolality or hypovolaemia , we examined in conscious rats the effects of intraperitoneal ( ip ) injections of 2 ml/100 g body weight of hypertonic saline or polyethylene glycol ( peg ; 250 mg/ml of 145 mm nacl ) on plasma adh and angiotensin ii ( aii ) levels and of intracerebroventricular ( icv ) administrations of sar1-ala8-aii ( a competitive receptor blocker for aii ) on the plasma adh responses to the ip injections .
