查询词典 ischemia

Since the findings of Murry and Currie et al . that ischemic preconditioning and heat shock response could protect evidently myocardium against ischemia-reperfusion injury in the middle of 1980s, endogenous myocardial protection has drawn widespread attentions.

摘 要：自上世纪80年代中期Murry及Currie等分别发现缺血预适应(ischemic preconditioning， IPC)与热休克反应(heat shock response， HSR)具有明显的心肌保护作用以来，有关心肌内源性保护作用的研究引起了学术界的广泛关注。

麝香酮对4VO法所致完全性脑缺血模型其有明显的保护作用。

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.
