Research has suggested that catalase plays a role in mediating ethanol's psychopharmacological effects. Catalase is an enzyme that oxidizes ethanol to acetaldehyde. It has been reported that when catalase activity is reduced by 3-amino-1,2,4-triazole (AT), rats reduce their intake and preference for ethanol. The present study assessed the effects of AT on the brain amino acids levels following ethanol administration in Wistar rats. The study consisted of three parts. In the first part, we found no effects of acute and chronic intraperitoneally administered acetaldehyde on amino acids dialysate levels in nucleus accumbens. In the second part, AT was administered five hours prior to ethanol or its vehicle. Ethanol significantly affected the levels of taurine in rat pre-treated with AT. In the final part, ethanol was administered following the pre-treatment with AT but the dependent variable was the concentration of ethanol in the brain.
