【摘要】 目的:观察三皮汤对溃疡性结肠炎模型小鼠的疗效及探讨其治疗机制。方法:40只BALB/C小鼠随机分成正常组、模型组、柳氮磺胺吡啶(SASP)组和三皮汤组,每组10只。予以恶唑酮建立模型后,三皮汤组和SASP组分别给予三皮汤和SASP灌胃治疗,每天观察小鼠体重、大便、饮食等情况,十天后处死所有小鼠,剪取脾组织检测重量的变化,取其病变结肠观察组织学改变,并采用酶联免疫吸附法(ELISA)测定各组小鼠血清白细胞介素(IL)-2及IL-10的含量。结果:1.三皮汤组和SASP组溃疡性结肠炎模型小鼠症状较模型组有明显改善。2.模型组小鼠免疫器官脾组织明显萎缩,三皮汤组和SASP组小鼠脾组织重量较模型组有所增加。3.模型组小鼠血清IL-2表达水平较正常对照组明显下降,而IL-10水平则明显升高,治疗后三皮汤组IL-2含量较模型组明显升高(P＜0.01),IL-10含量下降,与模型组对比有统计学意义(P＜0.01)。结论:1.三皮汤具有抗溃疡性结肠炎的药理作用2.三皮汤能通过调节细胞因子间的网络平衡,改善机体免疫功能,控制肠道炎症,从而到达治疗溃疡性结肠炎的作用。更多还原

【Abstract】 Objective: To investigate the therapeutic effect of sanpi decotion in ulcerative colitis(UC) mice and discuss its therapeutic mechanism.Methods: Forty BALB/C mice were divided randomly and equally into normal group, model group, sulfasalazine (SASP) group, and sanpi decotion group, ten mice in each group. After set up the oxazolone colitis, SASP group and sanpi decotion group were treated with sulfasalazine and sanpi decotion respectively, to observe the weight、stool、food and drink situation of the mice every day. Killed all the mice on the tenth day, separated the spleen and weight it, got the colon and evaluated the histological changes of the damaged colonic tissues, and measured the interleukin(IL)-2 and IL-10 concentrations in serum by using the enzyme-linked immunosorbent assay(ELISA).Result: 1. The symptom of sanpi decotion group and SASP group UC mice had great amelioration compared to model group mice2.The immune organ spleen of the model group mice was conspicuous shrunk, and compared to model group, the weight of spleen in sanpi decotion group and SASP group was increased.3. The concentration of IL-10 in the serum was markedly increased in model group, and the expression of IL-2 was decreased, oral administration of sanpi decotion significantly increased the expression of IL-2, and down regulation the expression of IL-10 in the serum compared to the model group.Conclusion: 1. Sanpi decotion can certainly treat the UC model mice.2. Sanpi decotion can ameliorate the ulcerative colitis by regulate the balance of the cytokines, improve the function of immunity, and control the inflammation in the colon.更多还原
