Effect of resveratrol (RVT) and curcumin (CMN) on the proliferation of lipopolysaccharide (LPS)-stimulated lymphocytes. RVT and CMN were added in different concentrations (1, 5, 10, 20 μM) to LPS-stimulated lymphocytes. After 72 h of incubation, [³H]-thymidine (0·5 μCi/well) was added and the cells were harvested 16 h later and radioactivity incorporated was measured. As a control, cells + medium, cells + RVT/CMN, could not generate more than 5000 counts per minute (cpm). *P < 0·05 compared to cells cultured with LPS. The data are the mean ± standard error (s.e.) of triplicate determinants.
