The relationships between ambient temperature, body temperature, ethanol pharmacokinetics and behavioral sensitivity to ethanol were examined in C57BL/6 mice. Mice were injected intraperitoneally with 3.6 or 2.0 g/kg ethanol. Exposure to increasing ambient temperatures of 4-34°C immediately after ethanol injection resulted in a significant increase in body temperature, ethanol elimination rate and brain:blood ethanol concentration ratios in 3.6 g/kg ethanol-injected mice, but not in mice injected with 2.0 g/kg ethanol. As the mean body temperature increased from 26.0 to 38.2°C in the 3.6 g/kg mice, there was a 50% increase in ethanol elimination rate. Delayed (30 min) exposure to increasing ambient temperatures following injection of 3.6 g/kg ethanol resulted in a significant increase in ethanol elimination rate, a marked increase in the duration of loss of righting reflex and a decrease in ethanol concentration at the regain of righting reflex. The results indicate that temperature-induced changes in the absorption, distribution and elimination of ethanol do not appear to mediate the effects of temperature on behavioral sensitivity to ethanol in C57 mice.
