Background : Intestinal ischemia-reperfusion injury is a serious and widespread clinical problem. Trolox effectively prevents lipid peroxidation in oxidative stress and protects cell injury. The aim of this study is to investigate the effect of Trolox alone on the intestinal ischemia-reperfusion injury in strangulation ileus model, which has not been investigated previously. Methods : Twenty-eight Sprague-Dawley rats randomly divided into four groups were used. Group Laparotomy + Physiological Saline underwent laparotomy and was administered physiological saline; Group Laparotomy + Trolox was administered Trolox. Group Strangulation + Physiological Saline was administered physiological saline before reperfusion following strangulation ileus; Group Strangulation + Trolox was administered Trolox. Results : Histopathological study was evaluated and catalase, malondialdehyde, superoxide dismutase measurements were performed in intestinal samples. Serum biochemistry parameters were evaluated. The higher grade (grade >= 2) was significantly observed to decrease in Group Strangulation + Trolox when compared with Group Strangulation + Physiological Saline (p = 0.04). In Group Laparotomy + Trolox, when compared with Group Laparotomy + Physiological Saline, the higher grade was found to be significantly lower (p = 0,03). The catalase values were found to be significantly lower in Group Strangulation + Trolox, when compared with Group Strangulation + Physiological Saline, and in Group Laparotomy + Trolox, when compared with Group Laparotomy + Physiological Saline (p < 0.01). Conclusions : Trolox is a powerful antioxidant as well as effectively prevents ischemia-reperfusion injury of the strangulated intestine segment.
