title: [The effect of nootropics on impared learning performance in a pole jumping test after repeated ethanol administration].
abstract: The influence of ethanol administration (4 ml of 10% ethanol/d p.o.) for 6 and 13 d respectively, on learning behaviour of rats has been studied using an active avoidance reaction. While the formation of an active avoidance reaction was only insignificantly impaired by the application of ethanol for 6 d, the learning performance of rats showed a significant deficit after 13d of ethanol ingestion. Repeated nootropic pretreatment (d11 to 14 following first ethanol dose b.i.d.) resulted in an attenuation of learning deficits. The nootropics piracetam (100 mg/kg i.p.) methyl-glucamine orotate (225 mg/kg i.p.), meclofenoxate hydrochloride (100 mg/kg i.p.), pyritinol (100 mg/kg i.p.) and dihydroergotoxine mesilate (1 mg/kg i.p.) showed to be effective. The possible mechanism of action is discussed.
