Effect of vitamin E on oxidative stress status in small intestine of diabetic rat

Figure 1 Biochemical markers which indicate status of oxidative stress. Significant high levels of superoxide dismutase activity (A) were observed in the non-treated diabetic rats instead of low level of catalase activity (B); 8-isoprostan (C) and protein carbonyl (D) contents of the small intestine of the non-treated diabetic rats were also significantly high. Vitamin E-treated diabetic rats showed elevated levels of superoxide dismutase (A) and catalase activities (B) accompanying with significant decrease in 8-isoprostan (C) and protein carbonyl (D) contents.
