Effect of EPS on MDA (A); LDH (B); intracellular GSH level (C); CAT (D) and SOD (E) activity in PC12 cells. Cells were pretreated with 50–300 μg/mL EPS or 500 μM vitamin E (Vit E) for 24 h and then incubated in the presence of 150 μM H₂O₂ for 3 h. The control group was treated with fresh medium only under the same culture conditions. Data presented are the means ± SD of results from three independent experiments (## p < 0.01 vs. control; * p < 0.05 and ** p < 0.01 vs. H₂O₂-treated cells).
