Abstract
The effect of alcoholic patient sera on in vitro lymphocyte transformation was studied using mitogen-induced uptake of 3H-thymidine to measure blastogenesis. With pokeweed mitogen as the stimulus, transformation of normal lymphocytes in sera of alcoholics with either normal or fatty livers was not significantly different from that obtained in pooled human serum (PHS). However, in sera of patients with either alcoholic hepatitis or inactive cirrhosis mean transformation was significantly reduced (P 125I-labelled mitogens to the lymphocyte surface. These findings indicate that the inhibitory effect of sera from alcoholics is of potential in vivo importance, that the effect increases with the degree of heptocyte damage, and that it is unrelated to the nonhepatic metabolic affects of chronic alcoholism.
