Effect of Troxerutin on Oxidative Stress Induced by Sciatic Nerve Ischemia-reperfusion Injury in Rats

Troxerutin has antioxidant and anti-inflammatory properties and in this study, its antioxidant effect on the reduction of oxidative stress induced by ischemia-reperfusion sciatic nerve injury was investigated. In this study, 64 male rats were randomly divided into 8 groups as follows: 1- IR2: ischemia (3 hours) and reperfusion (2 days), 2- Trox+IR2: ischemia (3 hours) and reperfusion (2 days), 3- IR7: ischemia (3 hours) and reperfusion (7 days), 4- Trox+IR7: ischemia (3 hours) and reperfusion (7 days), 5- IR14: ischemia (3 hours) and reperfusion (14 days), 6- Trox+IR14: ischemia (3 hours) and reperfusion (14 days), 7- IR28: ischemia (3 hours) and reperfusion (28 days), 8- Trox+IR28: ischemia (3 hours) and reperfusion (28 days). The rats received 150 mg/kg troxerutin in one injection (single dose). After separation of serum, biochemical parameters of the serums such as NO, PON1, CAT, and GPX were measured. Troxerutin significantly increased the GPX and PON1 levels in groups that their reperfusion time was 2 and 14 days (P 0.05). There was no significant difference in the levels of NO and CAT between the groups received troxerutin and control groups (P 0.05). Troxerutin relatively decreased the oxidative stress in the sciatic nerve ischemia-reperfusion injury by increasing the level of antioxidant enzymes.
