Figure S1. Effects of luteolin on lens opacity in H2O2-induced cataract. Lenses were pretreated with luteolin (0.01, 0.05 and 0.1 mg/mL) for 24 h, followed by incubation with H2O2 (1 mM) for another 24 h and then recovered in fresh medium for 48 h. Data are expressed as the mean ± SEM (n = 6); ##P < 0.01, compared with the normal control group; **P < 0.01 compared with the H2O2 treatment group. (TIF 584 kb)
