title: [Therapeutic usefulness of antioxidant drugs in experimental intestinal reperfusion syndrome].
abstract: The intestinal reperfusion injury has been studied in Sprague-Dawley rats weighing 200 g. Intestinal ischemia has been induced by clamping the Superior Mesenteric Artery (SMA) for 120 minutes. In order to parallel clinical situations, free radical scavengers (allopurinol [ALLO]) and superoxide-dismutase [SOD] were inoculated at a low perfusion rate through the femoral vein during the last 20 minutes of the ischemic period. Both drugs have decreased the mortality rate (from 70% in control group, to 40%) and the mean percentage of damaged intestine (30.89% vs. 23.84% and 24.70%). Histologically, ALLO was less effective than SOD (12.54 control; 8.40 SOD; 11.54 ALLO). The modification of glucose, SGOT, SGPT and LDH found in all the ischemic animals shows the hepatocellular injury induced by intestinal reperfusion.
