Genetic differences in the hyperglycemic response to acute ethanol exposure and ethanol-induced conditioned taste aversion were examined using inbred mice. Adult male C57BL/6J and DBA/2J mice were injected with ethanol (0-6 g/kg, I.P.) and blood glucose levels determined over 4 h. C57 mice demonsrated greater dose-dependent elevations in blood glucose compared to DBA mice. In a conditioned taste aversion procedure, water deprived mice received ethanol injections (1-4 g/kg, I.P.) immediately after access to a NaCl flavored solution. DBA mice developed aversion to the ethanol-paired flavor at a lower dose (2 g/kg) than C57 mice. These results provide further support for a possible inverse genetic relationship between sensitivity to ethanol-induced hyperglycemia and sensitivity to conditioned taste aversion.
