title: Selective breeding in mice for severity of the ethanol withdrawal syndrome.
abstract: Starting with a foundation population of 200 genetically heterogeneous mice (HS/Ibg), selective breeding has been initiated for a multivariate index of the ethanol withdrawal syndrome. This paper discusses the advantages of using multivariate indices to define pharmacological concepts. The seven variables included in our multivariate index are described. Because five of the seven variables showed a significant sex difference, separate principal component analyses were performed to establish selection indices appropriate for each sex. The study employs within-family mating to minimize inbreeding and includes replicate high, low, and control lines. These selectively bred lines should eventually provide a useful animal model for studying physiological and neurological mechanisms that may be involved in the ethanol withdrawal syndrome.
