a Protective effect of BME (100 µg/ml) against H₂O₂ (300 µM for PC12 and 500 µM for L132 cells) induced lipid peroxidation in PC12 and L132 cells. b Effect of BME (100 µg/ml) on H₂O₂ (300 µM for PC12 and 500 µM for L132 cells) induced decrease of mitochondrial membrane potential determined by spectrofluorimetric method. The data are presented as mean ± SEM of three independent experiments. *p < 0.05 versus the respective control group and ^# p < 0.05 versus the respective H₂O₂ treated group
