摘要
目的:探讨复方苦参汤对溃疡性结肠炎(UC)大鼠的作用及机制。方法:采用2,4,6-三硝基苯磺酸(TNBS)诱导溃疡性结肠炎大鼠模型,用不同剂量的复方苦参汤进行干预,检测结肠组织丙二醛(MDA)、一氧化氮合酶(i NOS)和一氧化氮(NO)水平,以及髓过氧化物酶(MPO)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-Px)活性,观察UC大鼠一般情况和结肠组织形态变化。结果:UC大鼠结肠组织MDA(P<0.05)、i NOS(P<0.01)和NO(P<0.01)水平及MPO(P<0.01)活性显著高于正常对照组,SOD(P<0.01)和GSH-Px(P<0.05)活性显著低于正常对照组;复方苦参汤高剂量组治疗后可明显降低UC大鼠结肠组织中MPO(P<0.01)、MDA(P<0.05)、i NOS(P<0.05)和NO(P<0.01)水平,增加SOD(P<0.01)和GSH-Px(P<0.05)活性,其疗效呈剂量依赖性。同时大鼠的一般情况及结肠组织形态亦得到明显改善。结论:复方苦参汤能显著抑制UC大鼠氧化应激反应,减轻结肠炎症损伤,具有较高的临床治疗价值。
