a Effect of BME on DNA damage induced by H₂O₂ in PC12 and L132 cells. a Control cells without any treatment, b 100 μg/ml BME, c H₂O₂ (300 µM for PC12 and 500 µM for L132) for 24 h d cells pre-treatment with 100 μg/ml BME for 1 h and then exposed to H₂O₂ (300 µM for PC12 and 500 µM for L132) for 24 h and (b). The tail length of the comet was measured in each cell using image pro^® plus software and represented as percent tail movement. 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
