Glutamine-induced alterations in the content of brain amino acid neurotransmitters in rats with different alcohol motivation.

Abstract

The 10-day administration of glutamine (500 mg/kg per day) with the drinking water to adult albino rats with different alcohol motivation resulted in a significant increase in the content of glutamate, GABA and taurine in the brain. The level of glycine was decreased only in the ethanol-preferring animals. The results obtained are discussed in terms of a possible role of the amino acid neurotransmitters, particularly GABA, in the antialcoholic action of glutamine.
