title: Voluntary alcohol intake is attenuated in two-kidney, one-clip, but not in one-kidney, one-clip Goldblatt hypertensive rats.
abstract: Voluntary alcohol intake was examined in two models of renovascular hypertension known to differ in their effects on the renin-angiotensin system. In experiment 1, Two-Kidney, One-Clip (renin-dependent) hypertensive rats (T-K,O-C) or their sham operated controls were offered limited access to alcohol for 1 hr each day. Over a four week period the T-K,O-C rats drank significantly less 3% and 6% (w/v) alcohol solution than the sham operated controls. In experiment 2, One-Kidney, One-Clip (renin-independent) hypertensive rats or their sham operated controls were offered alcohol on a similar limited access basis. Over a four week period, the O-K,O-C rats did not show a reduction in the intake of either a 3% or 6% alcohol solution compared to the sham operated controls. These results provide further documentation for the role of the renin-angiotensin system in modulating alcohol intake. The process by which this system might influence alcohol intake is outlined.
