摘要: 目的: 研究西红花酸对小鼠脑缺血再灌注(CIR)损伤的保护作用。方法: 采用CIR 模型,观察西红花酸对CIR 小鼠脑水肿、脑毛细血管通透性及脑组织中乳酸脱氢酶(LDH)、超氧化物歧化酶(SOD)、谷胱苷肽过氧化酶(GSH-Px)活性和丙二醛(MDA)、NO 含量的影响。结果: 与CIR 模型组比较,西红花酸(50、100 mg kg)连续5 d 灌胃能减少CIR 小鼠脑组织含水量、伊文思蓝和MDA、NO 含量,提高脑组织中LDH、SOD、GSHPx活性,差异具有统计学意义。结论: 西红花酸对小鼠CIR 损伤有一定的保护作用,其作用机制可能与西红花酸抗氧化、降低NO 含量有关。

Abstract: AIM: To research the protective effects of crocetin on cerebral ischemia-reperfusion (CIR)injury in mice.METHODS: The effects of crocetin on brain edema , brain capillary permeability , the activities of lactate dehydrogenase (LDH), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) in brains and the contents of malondialdehyde (MDA)and nitric oxide(NO)in CIR model mice were observed.RESULTS: Compared with the CIR group , crocetin (50 ,100 mg/kg for 5 d )decreased the content of water , Evans blue , MDA and NO in mice brain tissue , and increased LDH 、SOD and GSH-Px activity in brains of CIR mice , with statistical significance.CONCLUSION: Crocetin has protective effects on cerebral ischemia-reperfusion injury in mice , the mechanism may be related to its anti-oxidative activity and inhibition of NO overproduction.
