Preliminary Reports Animal Studies


Small doses of ethanol (1 or 2 g/kg 20% w/v) caused increased motor activity in rats and mice as measured by an Animex activity meter. This effect was prevented by pretreatment with the tyrosine hydroxylase inhibitor α-methyl-p-tyrosine methyl ester hydrochloride, in doses of 40 or 200 mg/kg which per se caused no significant depression of motor activity. The data implicate a role for newly synthesized catecholamines in ethanol-induced motor stimulation.
