[en] The present study investigated the possible modulatory action of oral taurine supplementation on the rewarding and aversive properties of low and high ethanol doses in male Wistar rats. A vinegar odor stimulus was daily paired with either ethanol (0.3 or 2.0 g/kg) or saline. In addition, half of the rats were supplemented orally with taurine (0.5 g/kg/day). After eight conditioning sessions, all rats were tested for their vinegar stimulus preference or aversion. In nontaurine-treated rats, 2.0 g/kg ethanol conditioning induced a significant aversion for the vinegar stimulus, while there was no preference after 0.3 g/kg ethanol conditioning. However, in taurine-supplemented rats, the 2.0 g/kg ethanol-induced aversion for the stimulus was decreased significantly, while the rats administered the lower ethanol doses, 0.3 g/kg, in combination with taurine supplementation, demonstrated a significant stimulus preference. Such results suggest that taurine modulates some of the aversive or rewarding effects of ethanol.
