To investigate the role of platelet-activating factor (PAF), neutrophils in ischemia-reperfusion-induced liver injury and their possible mechanism, PAF and the degree of neutrophil infiltration in liver tissue and the preventive effects of PAF antagonist kadsurenone were evaluated in this study by means of a partial liver ischemia model, in which it was induced by clamping only left and median lobes of the liver without causing intestinal congestion. The present study was undertaken to find out the mechanism of liver ischemia-reperfusion injury and preventive effect of kadsurenone. The results indicate that in early stage of reperfusion liver injury possibly caused by the generation of free radicals, declined of autioxidant defence and increased Ca２＋ influx, and in the later stage of reperfusion injury was mainly mediated by accumulation of PAF in the liver, which elicits the release of polymorphonuclear leukocytes induced toxical free radical, endothelial damage, microcirculatory collapse. The authors conclude that the effectiveness of antagonist kadsurenone in protecting against ischemiareperfusioninduced liver injury is due not only to their action in preventing the direct effects of PAF, but also to their ability to inhibit both PAF priming and PAF dependent feedback processes, thus preventing escalation of auto generated inflammatory damage.
