Viability of L02 cell pretreatment with H2O2 and LMWSPs by the MTT assay. Cells were incubated with the indicated concentrations of H2O2 for 24 h, and the effects of H2O2 on the L02 cells were analyzed. b Effects of LMWSPs in different concentrations (0–1000 μg/mL) on the L02 cells. The bar graph represents mean ± SE (n = 3), *P < 0.05, **P < 0.01 (compared with the blank control)
