The role of nuclear factor kappaB in intestine injury induced by hepatic ischemia reperfusion was investigated. Eighteen male Wistar rats were divided into 3 groups randomly: sham operation group (group A), hepatic ischemia reperfusion group (group B) and hepatic ischemia reperfusion plus pyrrolidine dithiocarbamate (PDTC) group (group C). The rats in group A were only subjected to laparotomy, those in group B underwent partial hepatic ischemia reperfusion (ischemia for 1 h and reperfusion for 2 h) and those in group C underwent the same procedure as that of group B but received PDTC 200 mg/kg i. v. before and after ischemia. After reperfusion, tissues of jejunum and venous blood were obtained for measurement of TNF-α, MDA and MPO. The levels of TNF-α in jejunum and venous blood, the levels of MPO in jejunum in group B were significantly higher than those in group A and group C (P<0.05). There was no significant different in the levels of MDA between group B and group C. The severity of histological intestinal injury in group B and group C was similar. Hepatic ischemia reperfusion caused intestine injury, NF-kappaB may play an important role in this course and the targeting of upstream components of the inflammatory response, such as NF-kappaB, may have important therapeutic applications.
