Abstract

BACKGROUND: Intestinal ischemia-reperfusion (I/R) injury can lead to multiple organ failure and death. The aim of this study wasto 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 minischemia followed by intraperitoneal 2 mcg /kg iloprost and 120 min reperfusion). At the end of the experiment, ileum specimens werestained using hematoxylin-eosin and histopathologically evaluated using the Chiu score. Isometric contraction–relaxation responseswere 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-reperfusioninjury. We concluded that further clinical and experimental studies for iloprost are needed.

Özet

AMAÇ: İntestinal iskemi-reperfüzyon (IIR) hasarı çoklu organ yetersizliği ve ölüme yol açabilir. Bu çalışmanın amacı, intestinal iskemide reperfüzyon öncesi uygulanan pentoksifilin ve iloprostun etkilerini araştırmaktır. GEREÇ VE YÖNTEM: 25–300 gr agırlığında 25 Wistar-Albino cinsi sıçan, her bir grupta beş sıçan olacak şekilde beş gruba ayrıldı: Kontrol grubu (n=5), sham grubu (n=5 IR yok), IR grubu (n=5, 45 dk iskemi 120 dk reperfüzyon), IR+Ptx grubu (n=5, 45 dk iskemiyi takiben 50 mg/kg intraperitoneal pentoksifilin ve 120 dk reperfüzyon), IR+IL (n=5, 45 dk iskemiyi takiben 2 mcg/kg intraperitoneal iloprost ve 120 dk reperfüzyon). Deney sonunda ileum örnekleri hemotoksilen-eosin ile boyandı ve histopatolojik olarak Chiu skorlamasına göre değerlendirildi. Izometrik kasılma –gevşeme cevapları organ banyosu kullanılarak kaydedildi. BULGULAR: Pentoksifilin histopatoljik ve kasılma –gevşeme cevapları açısından anlamlı düzelme sağladı. İloprost reperfüzyon hasarını düzeltmesine rağmen bu düzelme istatistiksel olarak anlamlı değildi. TARTIŞMA: Bulgularımıza göre pentoksifilin incebağırsak iskemi-reperfüzyon hasarından korumada ümit verici olabilir. Öte yandan, iloprost için daha ileri klinik ve deneysel çalışmalara gereksinim duyulmaktadır.
