近年来人们提出,心肌缺血再灌注损伤是由于产生了活性氧自由基。自由基清除剂对缺血再灌注引起的心肌损伤有一定保护作用,活性氧自由基对细胞的损伤也是明确的。但这些都是间接证明缺血再灌时可能产生了活性氧自由基。电子自旋共振(ESR)是检测自由基
In recent years, people have suggested that myocardial ischemia-reperfusion injury is due to the generation of reactive oxygen species. Free radical scavengers have a protective effect on myocardial injury induced by ischemia-reperfusion. The damage of reactive oxygen species to cells is also clear. But these are all indirect evidence that reactive oxygen species may be produced during ischemia reperfusion. Electron spin resonance (ESR) is the detection of free radicals
