title: Ethanol consumption and hepatic enzyme activity.
abstract: Enzyme activity and ethanol consumption were measured in an F2 generation derived from the C57BL and C3H inbred mouse strains. A significant correlation (0.25) was found between alcohol dehydrogenase activity and ethanol acceptance in the F2 generation. Mass selection from a genetically heterogenous mouse stock, HS/Ibg, has yielded high ethanol acceptance (HEA) and low ethanol acceptance (LEA) lines of mice. The mean ethanol acceptance scores for the fifth generation of these lines are 1.008 and 0.606, respectively. The total liver alcohol dehydrogenase activity was found to be 24% higher in the HEA line than in the LEA line after five generations of selective breeding. No association between cytosolic aldehyde dehydrogenase activity and ethanol acceptance was found in either the F2 generation or the fifth generation of the selectively bred lines.
