Effect of n-dipropylacetate and L-glutamine on gamma amino-n-butyric acid levels in brains of rats intoxicated with ethanol.

The concentrations of gamma-amino-n-butyric acid in brains of rats intoxicated with half intraperitoneal LD50 ethanol were determined at various times and found increased at early times (10 min) and decreased later (1 to 3 hours). The concentration tended to be restored to normal values upon administration of n-dipropylacetate (400 mg/kg) or L-glutamine (340 mg/kg). The treatment with both substances showed a positive interaction with an overall positive effect greater than the sum of each.
