临床观察到，脑栓塞患者血管再通后，患者症状反而加重，即缺血可导致脑损伤，再灌注还会进一步加重损伤。这种损伤与再灌时组织中大量氧自由基产生有关。丙二醛（MDA）是体内氧自由基作用于细胞膜上不饱和脂肪酸所产生的过氧化脂质代谢产物。它一旦形成，便相对稳定。因此，笔
Clinically observed, after recanalization of patients with cerebral embolism, the patient’s symptoms actually aggravate, that ischemia can lead to brain damage, reperfusion will further aggravate the injury. This damage and reperfusion tissue in a large number of oxygen free radicals related. Malondialdehyde (MDA) is a lipid peroxide metabolite produced by oxygen free radicals acting on the unsaturated fatty acids in the cell membrane. Once formed, it is relatively stable. So, pen
