Measurement of phosphatidylcholine hydroperoxide in mild ischemia-reperfusion injury in rat intestine.

In the pathogenesis of intestinal ischemia-reperfusion injury, the measurement of lipid peroxides needs to be established. Sprague-Dawley rat intestines were assessed after 30 minutes of occlusion of the superior mesenteric artery followed by reperfusion at 30, 60, 120, 180, 360 minutes. Grade of the mucosal injury, accumulation of the activated neutrophils and ICAM-1 expression were transiently increased after reperfusion.
