[en] The extracellular changes of amino acids glutamate, taurine and GABA in the nucleus accumbens of freely moving rats were estimated using the microdialysis technique following acute and chronic ethanol injections (1, 2, and 3 g/kg body weight). Compared to baseline values, taurine increased by 154%, 142% and 162%, 20 min after the acute injection of, respectively, 1, 2 and 3 g/kg body weight ethanol, while 40 min after ethanol injection, taurine had increased by 124%, 146% and 168%. No changes in either glutamate or GABA were detected at any time points assayed. In the rats which had received chronic ethanol administration prior to a further acute ethanol injection (1, 2, and 3 g/kg body weight), taurine increased by 138%, 144% and 180%, 20 min after the ethanol injection, and at 40 min post ethanol injection taurine had increased by 134%, 160% and 158%, compared to the basal baseline value. No significant changes were observed in either glutamate or GABA microdialysate content in these chronic studies. The biological role played by taurine after acute ethanol injection in the nucleus accumbens remains unclear but may be associated with a yet, undefined mechanism, in reducing the cytotoxicity of ethanol.
