Protective effect of LMWSPs on L02 cells impaired by H2O2. a ROS level was determined by measuring the fluorescence of L02 cells under a confocal microscope. a: Wt; b: 2000 H2O2 + 0 peptides; c: 2000 H2O2 + 500 μg/mL peptides; d: 2000 H2O2 + 1000 μg/mL peptides. b Quantification of intracellular ROS production in damaged and normal cells. Data are expressed as mean ± SE, n = 3, **P < 0.01 (compared with H2O2 control group). c NO level was determined by measuring the fluorescence of L02 cells under a confocal microscope. a: Wt; b: 2000 H2O2 + 0 peptides; c: 2000 H2O2 + 500 μg/mL peptides; d: 2000 H2O2 + 1000 μg/mL peptides. d Quantification of intracellular NO production in damaged and normal cells. Data are expressed as mean ± SE, n = 3, **P < 0.01 (compared with H2O2 control group)
