Effect of sino on the levels of inflammatory cytokines. a Cells viability at different concentrations of sino (25, 50, 100 μg/ml) was determined. Then, for the assay for NO (b), TNF-α (c), IL-6 (d), PGE2 (e) and IL-1β (f) with ELISA kits was determined. The values are presented are the mean ± SD (n = 3 in each group) of three independent experiments, *p < 0.05, **p < 0.01 compared with LPS group; △p < 0.05, △△p < 0.01 compared with con group
