缺氧预激和自由基清除剂对心脏缺氧应激耐受力的影响被研究,结果表明:缺氧预激显著增强了心脏对缺氧应激的耐受力,这可能与缺氧预激动员了心脏内在的自由基清除机制有关。外源性自由基清除剂SOD,VitE,VitC也有同样的增强心脏耐受缺氧应激的作用。
The effects of hypoxia preconditioning and free radical scavenger on cardiac hypoxia stress tolerance were studied. The results showed that hypoxia preconditioning significantly enhanced cardiac tolerance to hypoxia stress, which may be related to hypoxia preconditioning Agitated the heart’s intrinsic free radical scavenging mechanism. Exogenous free radical scavengers SOD, VitE, VitC also have the same heart to enhance hypoxia stress.
