Abstract | BACKGROUND/AIMS: METHODOLOGY: Forty-eight male 200-250 g Spraque-Dawley rats in six groups were used to determine the biochemical and histopathological changes after a 30-min ischemia and 30-min reperfusion. Pre-treatment with 50 mg/kg EGb 761 (Tebofortan, Karlsruhe-Germany) or 10-mL/kg saline was administered intravenously in the treatment and control groups. The superior mesenteric artery was occluded distal to the right colic artery and collateral arcades were ligated to provide complete ischemia. Ischemia was determined by the existence of pulseless or pale color of the small intestine. The return of the pulses and the reestablishment of the pink color were assumed to be the reperfusion of the intestine. Rats that were administered Egb 761 and saline were subjected to laparotomy, ischemia, or ischemia-reperfusion procedures. Mucosal lesions were graded from 0 to 5 in histopathological examination. Malondialdehyde and myeloperoxidase levels of the intestinal mucosa were measured. RESULTS: No significant difference was noted between the control and treatment groups regarding the histopathological changes. Although malonyldialdehyde and myeloperoxidase levels of the reperfusion + EGb 761 group were slightly higher than the laparotomy + saline group, they were significantly lower than the reperfusion + saline group.
