Özet
Objectives: To evaluate the effects of N-acetylcysteine (NAC) on the injury of intestinal ischemia-reperfusion. Methods: Forty-eight Wistar-Albino rats were divided into 6 groups: as control, ischemia, ischemia-reperfusion, ischemia + N-acetylcysteine, ischemia-reperfusion + N-acerylcysteine (IRN), and reperfusion + N-acetylcysteine (RN). Histopathologic examination was performed to all groups. In the tissue and plasma, and erythrocyte samples, malondialdehyde, superoxide dismutase, glutathione, and nitric oxide (NO) levels were evaluated. The present study was carried out in Trakya and Istanbul University, Edirne, Turkey between December 2002 and July 2003. Results: The most severe histopathological damage was seen in the intestinal ischemia-reperfusion group, and this damage was observed to be reduced by NAC administration. Lowest plasma malondialdehyde levels were observed in RN group. The tissue glutathione levels were found to be higher in RN group than those in IRN group. Conclusion: It was found that administration of NAC has important effects on the injury of intestinal ischemia, as well as, reperfusion in rats. N-acerylcysteine administration causes an improvement in the histopathologic findings of ischemia/reperfusion damages. The N-acerylcysteine treatment protects the antioxidant enzymes in the tissue, plasma, and the erythrocytes, which are crucially important in the intestinal schemia/reperfusion injury in rats.
