Abstract: | An animal model of alcohol dependence is being produced by selecting mice for differences in severity of ethanol withdrawal seizures. Replicate lines of high-dependence (HA), low-dependence (LA), and control (CA) mice are being developed by within-family selection. After seven generations both (replicate) HA and LA lines have separated significantly. Some of the difference between the replicate pairs of HA and LA in the early generations was due to differences in ethanol consumption. This difference in consumption may be attributable to a difference in metabolic rate or activity level rather than to a difference in ethanol preference. Females are more susceptible to seizures than males; this appears to be due partly to their higher consumption of ethanol during treatment.This research was supported in part by Grant AA-03527 from the National Institute of Alcohol Abuse and Alcoholism to the University of Colorado Alcohol Research Center. |
