中文摘要
目的观察大黄素、茶多酚和鱼腥草素钠对2,4,6-三硝基苯磺酸(TNBS)诱导大鼠结肠炎的治疗作用,并探讨其可能的免疫机制。方法将90只SD大鼠随机分为9组,采用TNBS诱导建立炎症性肠病大鼠模型。造模24 h后,定时ig给予药物治疗组大鼠相应剂量的药物,空白对照组和模型组大鼠ig给予同体积的蒸馏水,每天1次,持续14 d。观察大鼠每日的体重变化、大便状态,解剖大鼠后观察结肠组织的大体改变和病理变化,检测大鼠血清中肿瘤坏死因子α、白介素-lβ(IL-lβ)、IL-4、IL-10的水平及丙氨酸氨基转移酶、天门冬氨酸氨基转移酶、肌酐的含量。结果与空白对照组比较,药物治疗组和模型组大鼠的一般情况较差,体重明显减轻,炎性指标显著减低;与模型组比较,除鱼腥草素钠低剂量组外,其余药物治疗组大鼠的体重均明显增加,炎症情况明显缓解,炎性指标显著降低;茶多酚和鱼腥草素钠高剂量组改善炎症的效果显著优于低剂量组的,而鱼腥草素钠低剂量组的抗炎效果与模型组的比较无显著性差异。结论大黄素、茶多酚和鱼腥草素钠均对大鼠结肠炎有治疗作用,其中,茶多酚和鱼腥草素钠的治疗作用存在量效关系。
