摘要
目的:观察苦豆子总碱对实验性结肠炎大鼠的结肠组织中超氧化物歧化酶(SOD)、丙二醛(MDA)、一氧化氮(NO)、髓过氧化酶(MPO)表达的影响。方法:将SD大鼠随机分成6组,采用三硝基苯磺酸(TNB)灌肠法,制备实验性结肠炎大鼠模型。第2天开始灌胃,3周后测定结肠黏膜组织中SOD活力、MDA含量、NO含量、MPO活力。评价大鼠的症状和结肠组织学变化。结果:造模组大鼠结肠炎黏膜SOD值显著低于正常组,MDA,NO,MPO值显著高于正常组(P<0.05)。各治疗组均能升高SOD值,降低MDA,NO,MPO值(P<0.05),改善大鼠的症状和结肠组织学损伤(P<0.05)。结论:苦豆子总碱可能通过抑制氧自由基反应,抑制NO生成,抗炎作用来改善或减轻结肠炎症状。
Objective: To investigate the effects of total base of Sophora alopeeuroides on expression of SOD, MDA, NO, MPO in rots with experimental colitis (UC). Method: SD rats were randomized into 6 groups and colitis was induced by administrating 2,4,6-trinitrobenzesulphonic acid(TNB) recatlly in rats. Rats were given drug by stomach after the first day for 3 weeks, and sacrificed at 23^rd day to determine the content of MDA and activities of SOD, NO, MPO in colonic mucosa, and to estimate the symptom and colonic histology. Result: In UC rats, SOD was significantly decreased whereas MDA, NO, MPO were increased when compared with the normal group( P 〈 0.05). In all treatment groups, Sophora alopecuroides could increase SOD, decrease MDA, NO, MPO( P 〈 0.05), and improve the symptoms and histological damages. Conclusion: The total dose of S. alopecuroides may ameliorates or alleviate the symptoms of UC through inhibiting oxygen free radical reaction, decreasing the generation of NO and exerting anti-inflammatory effects.
