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.
