It was first described by Murry who showed that IPC decreased the infarct size induced by a 40 minutes of coronary occlusion in a canine model of myocardial ischemia and reperfusion.

首先提出这一概念的是Murry等，他们在实验中发现数次短暂的缺血预处理后能使心肌更好对抗缺血再灌注损伤。

Methods The global cerebral ischemia/reperfusion injury model was established by the four-vessel occlusion (4VO) method, and then the model animals sere given high-middle-and low-dose muscone. Meanwhile, sham-operation group, model group, and positive control group were also set up. The rats neuroethology behavior, and the contents of superoxide dismutase, malondialdehyde and excitatory amino acid in is-chemic brain tissue were examined.
