摘要 目的将葛根芩连汤饮片纳米化治疗幼鼠实验性结肠炎,并与常态中药、柳氮磺胺吡啶进行疗效比较。方法将56只6周龄SD雄性大鼠随机分为7组每组8只,其中两组为正常对照,剩余各组依次为模型对照组、空白对照组、常态中药组、纳米中药组和水杨酸柳氮磺胺吡啶(SASP)组,除正常对照组外均采用溶于50%乙醇的三硝基苯磺酸(TNBS)一次性给幼鼠灌肠的方法复制幼鼠的结肠炎(IBD)模型。将一个正常对照组与模型对照组比较判断模型是否复制成功,其余组分别予以等体积生理盐水、常态中药饮片水煎剂、纳米中药水冲剂和SASP水溶液灌胃10天,然后通过形态学积分、OBT积分、MPO值与组织形态学来判断治疗效果。结果纳米化的葛根芩连汤在改善IBD幼鼠的肠粘连与溃疡等形态学指标、降低OBT、减轻局部的炎症程度(MPO水平)方面,其疗效明显优于同剂量的常态中药组(P<0.05)。虽然纳米中药组在对OBT与MPO的水平影响方面与SASP组相比没有明显差别(P>0.05),但其减轻局部粘连和溃疡等组织形态学指标方面有明显优势(P<0.05)。结论葛根芩连汤纳米粒对幼鼠IBD有明显的治疗作用,优于常态中药和SASP。
