title: Selective breeding of rats for differences in reactivity to alcohol: an approach to an animal model of alcoholism. III. Some physical and behavioral measures.
abstract: The results of selective breeding for differential impairment of motor activity after alcohol injection is shown for the first 13 generations of the LA and MA rat strains. In F13 rats, the mean decrement of activity after 1.5 g ethanol per kg i/p. is 90% for MA rats and 42% for LA rats, the strain difference significant at a "p" of 1.8 x 10(-11). Blood alcohol levels, body weight, litter size, organ weights and induction of taste aversion to alcohol and lithium chloride are described for these strains in various of the generations. Although strain differences are apparent on some of these measures, none are of a degree or kind which offers more than a speculative explanation of the large difference between the strains in their central nervous system sensitivity to alcohol.
