Glutathione peroxidase activity (Gpx) (a), glutathione reductase activity (GR) (b), reduced glutathione (GSH) (c), and glucose-6-phosphate dehydrogenase activity (G6PDH) (d). Nondiabetic (ND), diabetic (D), diabetic treated with insulin (D+I), diabetic treated with metformin (D+M), and diabetic treated with insulin and metformin (D+I+M). ∗ p < 0.05 versus ND, # p < 0.05 versus D, and & p < 0.05 versus D+I.
