title: Treatment with edaravone improves the survival rate in renal warm ischemia-reperfusion injury using rat model.
abstract: Renal ischemia-reperfusion (I/R) injury during renal transplantation is a significant cause of renal dysfunction. The pathological role of free radicals in this process is a major concern. We investigated the effect of a free radical scavenger, edaravone (MCI-186), in renal I/R injury. Male Lewis rats (270 to 320 g) were used for the model. The right kidney was harvested and left renal artery and vein were clamped as laparotomy. The kidney was reperfused after 90 minutes of ischemia. Edaravone (10 mg/kg) was delivered intravenously before ischemia and after reperfusion to prevent the neutrophil activation. In the nontreatment I/R group, no rat survived beyond 4 days. However, in the edaravone I/R treatment group, one among five rats survived more than 7 days. These results suggested that treatment with edaravone ameliorated renal I/R injury, and that the agent has the potential to ameliorate preservation injury in renal transplantation.
