Figure 1: Effect of rice bran hydrolysates on PBMC proliferation. PBMCs were cultured in RPMI 1640 containing (A) rice bran hydrolysates (400-1 600 μg/mL) alone, and (B) with PHA (10 μg/mL) or PHA with or without CsA (2 μM) for 72 h. Cell viability was determined by MTT assay. Each bar represents mean ± SD of 3 experiments. *P < 0.05 vs. Control, #P <0.05 vs. PHA. PBMC: peripheral blood mononuclear cell, CsA: cyclosporine A, PHA: phytohemagglutinin, RBH: rice bran hydrolysates.
