MDA, SOD, GSH, GSH-Px and CAT levels of hydrogen peroxide damaged human embryonic kidney 293 T cells. Values presented are the mean ± standard deviation. Different letters indicate significant differences from each other at the level of p < 0.05 according to Tukey’s honestly significant difference. Normal: untreated human embryonic kidney 293 T cells; model: hydrogen peroxide induced oxidative damage human embryonic kidney 293 T cells
