摘要 【目的】探讨万汶对失血性休克兔复苏过程中氧自由基的影响。【方法120只兔随机分为四组:对照组;失血性休克组;万汶组和林格组。测定休克前、休克1h和复苏后2h血浆中超氧化物歧化酶活性(SOD)和丙二醛(MDA)的含量。【结果】对照组MDA、SOD含量各时点比较无显著性差异;与对照组相比,休克1h时机体血中SOD活性明显下降,MDA水平明显升高。与休克组相比,休克1h后用林格氏液复苏2h,SOD活性升高,MDA水平降低。与对照组相比,万汶可以明显提高机体血中SOD的活性,减少MDA的生成。【结论]万汶可抑制失血性休克兔血浆中MDA的产生,增强SOD的活性,减轻氧自由基造成的脂质过氧化反应,从而减轻和延缓失血性休克进一步的发展。
