Abstract

BACKGROUND: Intestinal ischemia-reperfusion (I/R) injury can lead to multiple organ failure and death. The aim of this study was to investigate the effects of pentoxifylline and iloprost administered before reperfusion in intestinal ischemia. METHODS: In total, 25 male Wistar Albino rats weighing 250–300 g were divided into five groups each comprising five subjects: control group (n=5), sham group (n=5, no I/R), I/R group (n=5, 45 min ischemia, and 120 min reperfusion), I/R + pentoxifylline group (n=5, 45 min ischemia following intraperitoneal 50 mg/kg pentoxifylline and 120 min reperfusion), and I/R + iloprast group (n=5, 45 min ischemia followed by intraperitoneal 2 mcg /kg iloprost and 120 min reperfusion). At the end of the experiment, ileum specimens were stained using hematoxylin-eosin and histopathologically evaluated using the Chiu score. Isometric contraction–relaxation responses were recorded using organ baths for contraction–relaxation responses. RESULTS: Pentoxifylline provided a significant improvement in response to histopathological and contraction–relaxation responses. Although iloprost provided recovery in reperfusion injury, it was not statistically significant. CONCLUSION: Our findings demonstrate that pentoxifylline may be promising in preventing small bowel ischemia-reperfusion injury. We concluded that further clinical and experimental studies for iloprost are needed.
