Abstract
After 37 generations, the AA and ANA rat lines developed for high and low voluntary alcohol consumption, were revitalized by crossing with hybrid (Brown Norwegian X Lewis) rats. The line difference in alcohol consumption continued, although initially diminished, after revitalization. The greater acetaldehyde accumulation and longer loss of righting reflex after ethanol administration of the ANAs persisted after revitalization, but significant line differences in motor impairment were no longer found. The line characteristics for open-field test behavior were also different than before revitalization. Of the previously-observed line differences that have now been reexamined, the level of blood acetaldehyde during ethanol metabolism appears to be the most closely related to the genetically-determined factors influencing alcohol consumption.
