title: Effect of FR167653 on small bowel ischemia-reperfusion injury in dogs.
abstract: IL-1 and TNF-alpha are known to be pleiotropic cytokines associated with various inflammatory conditions such as small intestinal injury after ischemia-reperfusion. FR167653 has been characterized as a potent suppressant of IL-1 and TNF-alpha production. The effect of FR167653 on intestinal reperfusion injury was investigated in a warm ischemia model of the canine gut. Sixteen mongrel dogs were divided into two groups: a control group and a FR group to which FR167653 was administered. Both the superior mesenteric artery and vein were clamped for 2 hr. Arterial pH, hepatic venous hemoglobin oxygen saturation, intramucosal pH, and the survival rate were well maintained in the FR group in comparison with the control group after reperfusion. FR167653 inhibited the expression of IL-1beta mRNA. Histologically, ischemia-reperfusion injury was more severe in the control group than the FR group. This study suggests that FR167653 inhibits proinflammatory cytokines and ameliorates ischemia-reperfusion injury of the small intestine.
