Fig. 3From: Effect of Moringa oleifera stem extract on hydrogen peroxide-induced opacity of cultured mouse lensEffects 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 groupBack to article page
