摘要 目的观察天星健骨胶囊对佐剂性关节炎大鼠足爪组织MMP-2、MMP-9表达的影响。方法采用注射弗氏完全佐剂制作大鼠佐剂性关节炎模型,将造模成功的50只SD大鼠随机分为模型组、天星健骨胶囊低、中、高剂量组(0.4、0.6、0.8 g/kg)、地塞米松组(2 mg/kg)各10只,另设正常组(10只)。观察各组大鼠足爪肿胀度;至28 d采用免疫组化法检测大鼠足爪组织中MMP-2和MMP-9蛋白的表达。结果模型组和正常组,肿胀度差异显著(P<0.01),各治疗组肿胀度与模型组比较均有下降(P<0.05或P<0.01),中药中、高剂量组MMP-2、MMP-9阳性密度明显降低(P<0.05或P<0.01)。结论天星健骨胶囊可明显改善佐剂性关节炎模型大鼠的症状,其机制可能与其下调MMP-2、MMP-9表达有关。
