Effects of MOSE and luteolin on ROS production and SOD, CAT activities in lenses. The fluorescent probe DCFH-DA was used to detect the ROS level in lenses pre-treated with MOSE (0.5 and 1.0 mg/mL) or luteolin (0.05 mg/mL) before H₂O₂ exposure. The fluorescent intensities are summarized in a. GSH content (b), and SOD (c) and CAT (d) activities were measured in lenses pretreated with MES or luteolin before H₂O₂ exposure. Data are expressed as the mean ± SEM (n = 6); ^##P < 0.01, compared with the normal control group; *P < 0.05, **P < 0.01, compared with the H₂O₂ treatment group
