摘要 目的:探讨大鼠肢体缺血/再灌注(LI/R)后心肌的损伤性变化及NO的保护效应。方法:制备LI/R动物模型,将Wistar大鼠随机分为4组(n=10):C(control)组、I/R组、L-Arg组和L-NAME组。用生物化学方法测定大鼠血浆CK、CK-MB及NO水平,测定心肌组织XOD、SOD、MDA含量。用BL-420生物机能实验系统监测大鼠MAP、LVSP、±dp/dtmax等。结果:LI/R后,血浆CK、CK-MB水平均明显升高(P<0.01);心肌组织SOD活性降低而MDA、XOD含量增加(P<0.01或P<0.05);MAP、LVSP、dp/dtmax、-dp/dtmax均降低(P<0.01或P<0.05);血浆NO水平在L-Arg组明显升高(P<0.01),在L-NAME组显著降低(P<0.05)。结论:大鼠LI/R可引起心肌损伤,机体的氧化应激状态可能是其发生机制之一;提高体内NO水平可在一定程度上减轻LI/R后心肌损伤的程度。
