摘要 目的研究侗药五味止泻汤对溃疡性结肠炎大鼠白介素-4(IL-4)和组织核因子(NF)-κB p65表达的影响并探讨其作用机制。方法采用2,4,6-三硝基苯磺酸和乙醇灌肠法制备UC大鼠模型,10天后观察大鼠疾病活动指数(DAI)和结肠黏膜损伤指数(CMDI),用ELISA法检测各组大鼠的血清IL-4的水平,运用免疫组化染色(SABC法)检测NF-κB p65表达。结果侗药五味止泻汤能降低大鼠结肠结肠DAI及CMDI评分(P<0.01),提高大鼠血清IL-4水平(P<0.01),并且降低NF-κB p65的表达(P<0.01)。结论侗药五味止泻汤对大鼠溃疡性结肠炎有良好的治疗作用,其作用机制可能是通过提高IL-4含量和抑制NF-κB p65的激活发挥治疗作用。
