title: In vivo effect of DDS on phytohemagglutinin (PHA)-induced lymphocyte transformation cultures in normal healthy volunteers.
abstract: Depression in PHA-induced lymphocyte transformation in peripheral blood has been observed in 15 healthy volunteers after administration of DDS (100 mg/day) for seven days. In vitro culture of lymphocytes obtained from these volunteers in DDS-free normal AB serum has not altered the blast cell numbers. Lymphocytes of these volunteers have been found to contain a significant amount of DDS, ranging from 0.42 to 3.2 micrograms per 10.6 lymphocytes.
