Effect of desglycinamide(9)-lysine(8)-vasopressin and prolyl-leucyl-glycinamide on oral ethanol intake in the rat.
Rats given ethanol in their drinking water at a concentration that permitted adequate fluid intake gradually accepted higher concentrations and consumed larger amounts of ethanol. These increases were augmented when daily subcutaneous injections of 1 microgram of desglycinamide9-lysine8-vasopressin (DGLVP) or 10 microgram of prolyl-leucyl-glycinamide (PLG) were given concomitantly. Nonsignificant changes in ethanol consumption were seen with injections of 1 microgram PLG, or 0.42 or 42 microgram of lysine8-vasopressin (LVP). In a second experiment 4 microgram DGLVP given every second day as a long-acting zinc phosphate complex, commencing after the increases in ethanol intake had taken place, failed to produce any change in ethanol consumption subsequently. In both Experiments 1 and 2, the rats were switched from forced ethanol intake to a choice between ethanol and tap water. On these tests there was only marginal evidence of peptide-produced changes in ethanol intake.
