Abstract:AIM: To explore probable mechanism underlying the therapeutic effect of针对实验性结肠炎的阿astagalus多糖(APS)。
方法: sprague-dawley大鼠是随机分裂的分为四组。用2、4、6-三硝基苯磺酸(TNB)诱导结肠炎。用结肠炎的大鼠用400 mg/kg的AP治疗7 d。通过结肠体重,结肠长度,结肠长度以及宏观和组织学评分评估治疗效应。通过流式细胞术测量了Peyers斑块中调节t(Treg)细胞的水平,并使用酶联免疫吸附测定法分析了结肠组织匀浆中的细胞因子。 The expression of related orphan receptor-γt (ROR-γt), IL-23 and STAT-5a was measured by Western blot.
RESULTS: After 7-d treatment with APS, the weight index of the colon, colonic weight, macroscopical and histological scores were decreased, while the colonic length was increased compared with the模型组。白介素(IL)-2,IL-6,IL-17,IL-17,IL-23和ROR-γT在结肠组织中的表达被下调,但是Peyers Patc中的Treg细胞在结肠组织中的HES,TGF-β和Stat5a上调。
结论:
