摘要 目的探讨地尔硫、N-乙酰半胱氨酸(NAC)和过氧化氢酶(CAT)联合应用对兔脊髓缺血再灌注(I/R)损伤的保护作用。方法阻断肾下腹主动脉及髂动脉建立兔脊髓I/R损伤模型,治疗组经阻断动脉灌注地尔硫、NAC和CAT混合盐溶液,检测丙二醛(MDA)、超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPx),观察实验兔行为学变化及损伤病理变化,并与单纯手术组作对照。结果治疗组SOD和GPx活性高于对照组,而MDA水平低于对照组(P<0.05)。病理学检查发现脊髓出血和神经细胞破坏治疗组较对照组轻。治疗组神经行为学评分优于对照组(P<0.01)。结论在脊髓缺血后应用地尔硫艹卓、NAC和GPx的混合盐溶液可以有效减少脊髓I/R损伤造成的损害。
