Effect of rutin on experimentally induced small intestinal ischemia reperfusion injury in rats: A biochemical and histopathological evaluation

Abstract

Background/Aim: The large amount of oxygen presented to the ischemic tissue in reperfusion causes the formation of excess free oxygen radicals and results in oxidative damage. Rutin is a flavonoid with potent antioxidant and anti-inflammatory effects. The aim of this study is to examine the effect of rutin on I/R-induced small intestinal (ileum) oxidative damage in rats. Methods: The animals were divided into three groups as follows: Intestinal ischemia-reperfusion (IIR), 50 mg/kg rutin+intestinal ischemia reperfusion (RIIR) and sham operation (Sham). Rutin was administered at a dose of 50 mg/kg by oral catheterization one hour prior to thiopental sodium anesthesia. Distilled water was administered with the same method to IIR and Sham groups as a solvent. To induce intestinal ischemia in RIIR and IIR groups, the superior mesenteric artery was suspended from the point where it left the aorta, and ischemia was induced for 45 minutes with the help of an atraumatic microvascular clamp followed by 60 minutes of reperfusion. Biochemical and histopathological examinations were performed on the dissected ileal tissues. Results: The amount of MDA and MPO activity increased, while tGSH levels and CAT activity decreased significantly in the intestinal tissue of the IIR group compared to sham group (P
