the hypothesis that genetic differences in opiate receptor concentration are involved in determining the sensitivity to some of the effects of alcohol was studied by comparing the hypothermic and analgesic effects of ethanol in four strains of mice that can be divided into three groups on the basis of their brain opiate receptor concentration : high ( cxbh ) , low ( cxbk ) and intermediate ( c57bl/6by and balb/cby ) .
