title: Renal artery stenosis: an example of how the periphery can modulate voluntary alcohol drinking.
abstract: Voluntary alcohol drinking, using a free-access procedure, was studied in rats three weeks after unilateral renal artery stenosis was produced by applying a 0.20 mm solid silver clip to the left renal artery (Two-Kidney, One-Clip, Hypertension). The group of animals with the arterial clip drank significantly less alcohol and more water than a sham-operated group. The two groups, however, drank similar amounts of a palatable glucose solution, suggesting that they did not differ in taste sensitivity. Blood alcohol levels measured for six hours following a 2.5 g/kg intraperitoneal injection of alcohol indicated that the difference in alcohol consumption between the two groups could not be accounted for in terms of differences in drug disposition or metabolism. These findings provide an example of a previously unknown type of control which originates in the periphery and contributes to the regulation of voluntary alcohol drinking.
