摘要 目的观察白芍总苷(TGP)对大鼠胶原性关节炎(CIA)足爪组织基质金属蛋白9表达和血清中炎性细胞因子IL-1β、TNF-α等水平的影响,以探讨其保护关节炎的机理。方法用鸡Ⅱ型胶原诱导建立CIA大鼠模型,造模后第7~27天ig给予TPG 25,50和100 mg.kg-1。用免疫组化法测足爪组织基质金属蛋白酶9的表达;用ELISA法测RA大鼠血清中炎性细胞因子IL-1β、TNF-α的含量。结果与模型组相比,白芍总苷大、中剂量组的足爪组织基质金属蛋白酶9阳性表达明显降低(P<0.05),白芍总苷大、中剂量使CIA大鼠血清中异常增高的IL-1β和TNF-α的水平降低(P<0.01)。结论白芍总苷对大鼠胶原性关节炎有明显抑制作用,其机制可能是与其下调基质金属蛋白-9的表达,降低血清促炎性细胞因子IL-1β、TNF-α的水平有关。
