Abstract
In guinea-pig isolated ileum from animals pretreated with Pertussis toxin, the acute inhibitory effects of normorphine and clonidine on electrically induced contractions were markedly attenuated whilst responses to acetylcholine and electrical stimulation were unaltered. Pertussis toxin treatment also reduced naloxone-precipitated withdrawal contractures in normorphine-dependent tissues. These results suggest that the acute and chronic effects of normorphine are mediated by the same mechanism, namely that of adenylate cyclase inhibition.Entities:
