摘要
目的观察盐酸小檗碱(berberine hydrochloride,BBR)对溃疡性结肠炎模型小鼠结肠组织TNF-α、IL-1β和IL-10表达的影响,探讨其治疗UC的可能作用机制。方法 BALB/c小鼠随机分为模型对照组、BBR低、高剂量组、柳氮磺吡啶阳性对照组和空白对照组。采用右旋葡聚糖硫酸钠法复制UC小鼠模型后,每日灌胃给药1次,连续7 d。实验期间每天观察小鼠一般情况并评估疾病活动指数(DAI);末次给药后解剖观察并评估结肠大体形态损伤指数(CMDI);组织切片染色,光镜下观察结肠组织的病理学变化并评估组织损伤指数(TDI);ELISA酶联法检测结肠组织中细胞因子TNF-α、IL-1β和IL-10的含量。结果与模型对照组比较,BBR治疗组小鼠的结肠炎临床表现明显改善,其DAI、CMDI和TDI评分显著下降,小鼠结肠组织中TNF-α、IL-1β水平均明显降低,IL-10水平升高(P<0.05)。结论 BBR能有效治疗UC小鼠的结肠炎症,其机制可能与其抑制结肠组织中TNF-α和IL-1β、提高IL-10的表达有关。
