Effect of BPA on the activity of the antioxidant enzymes, glutathione peroxidase (GSHPx), catalase (CAT), glutathione transferase (GST), and glutathione reductase (GR) in liver tissues. Data are presented as the mean ± SEM.
*Indicate significant change from control, at using ANOVA followed by Tukey-Kramer as a post-ANOVA test.
