摘要
目的:比较黄连总生物碱(TAC)与盐酸小檗碱(BER)对溃疡性结肠炎(UC)的治疗作用。方法:采用5%乙酸灌肠和5%葡聚糖硫酸钠(DSS)灌胃复合法制备小鼠UC模型。小鼠随机分为正常组、模型组、柳氮磺吡啶组、黄连总生物碱(TAC)高、中、低剂量(360mg/kg、180mg/kg、90mg/kg)组及盐酸小檗碱高、中、低剂量(170mg/kg、85mg/kg、42.5mg/kg)组。观察各组小鼠疾病活动指数(DAI)、血清丙二醛(MDA)含量以及结肠病理切片等指标的变化。结果:与模型组比较,各治疗组小鼠DAI与血清MDA含量有不同程度的下降;治疗组的结肠组织病理改变明显减轻。在相同给药剂量和含等剂量盐酸小檗碱的条件下,综合疾病活动指数(DAI)、血清丙二醛(MDA)含量以及结肠病理切片等指标,黄连总碱优于盐酸小檗碱。结论:在相同给药剂量和含等剂量的盐酸小檗碱条件下,黄连总生物碱对小鼠UC的治疗作用较盐酸小檗碱有一定的优势。
Objective: To compare the pharmacological effect of total alkaloids from coptis root(TAC) and berberine(BER) on ulcerative colitis(UC) treatment.Methods: The ulcerative colitis model was established by 5% dextran sulfate sodium(DSS) solution(ig) with intra colonic administration of 5% acetic acid solution.Mice were divided randomly into normal group,model group,sulfasalazine group,large,medium,low dosage(360mg/kg、180mg/kg、90mg/kg) TAC treated groups and large,medium,low dosage(170mg/kg、85mg/kg、42.5mg/kg) BER treated groups.The changes of disease activity index(DAI),contents of MDA in serum and histopathology of colon were obtained.Results: Compared with the model group,DAI and the contents of MDA in serum were decreased in different degree and the histopathological changes were attenuate.Conclusion: In total,the treatment effect of TAC on UC is better than BER.
