title: [The effect of adenosine and beta-endorphin on the contractions of the vas deferens in rats with various durations of ethanol narcosis].
abstract: Action of ethanol on animals with different predisposition to alcohol consumption depended on the level of ethanol metabolism or sensitivity of nervous system to alcohol. There was studied the ethanol effects on contraction of rat vas deferens. Such an approach enables to distinguish the metabolic effects from action on nervous system. It was shown, that dose of ethanol, which inhibits the contraction of rat vas deferens of by 50% is the same in both groups of rats, but the ED50 of adenosin and beta-endorphin were 1.7 and 4.7 times lower for vas deferens of predisposed rats. It's possible to suggest the differences between two groups of rats to be connected with the effects of ethanol on purinergic and endorphinergic system, but not with ethanol itself.
