[Effect of isolation stress on ethanol pharmacodynamics in the blood of rats].

Head space chromatography was used to study the rate of ethanol excretion as criterion of the activity of the ethanol-oxidizing enzymatic system. Isolational stress was shown to be one of the factors determining induction of the ethanol-oxidizing erzymatic systems. The isolation-induced activity of these systems was reduced by diazepam administration. This fact may evidence the existence of central regulation of the activity of the enzymatic systems that metabolize ethanol.
