Effect of resveratrol and curcumin on the proliferation of concanavalin A (ConA)-stimulated lymphocytes. ConA-stimulated lymphocytes were cultured with different concentrations (1, 5, 10, 20 μM) of resveratrol (RVT) and curcumin (CMN). After 72 h of incubation, [³H]-thymidine 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 ConA. The data are the mean ± standard error (s.e.) of triplicate determinants.
