title: T-lymphocytes and hepatitis B serology.
abstract: The incorporation of 14C-thymidine by peripheral blood lymphocytes stimulated by phytohemagglutinin (PHA) and the proportion and absolute number of E-rosettes were determined in 28 prostitutes and the results were correlated with hepatitis B virus (HBV) serology. Women were tested for hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs) as well as for antibody to the hepatitis B core antigen (anti-HBc). It was found that women who were carriers of HBsAg had significantly lower incorporation of 14C-thymidine (median value 14451 counts per minute-cpm) compared to women positive for anti-HBc but negative for the other two markers (median value 28590 cpm) as well as to women negative for all the tested markers (median value 30600 cpm). No significant difference was found among the three groups studied with respect to either the absolute number or the percentage of E-rosettes. The results indicate that the presence of anti-HBc alone, is not related to the responsiveness of lymphocytes to PHA.
