摘要(Abstract):
[目的]探讨当归、阿魏酸钠关节腔注射对大鼠骨关节炎(OA)的疗效。[方法]40只大鼠木瓜蛋白酶法建立双膝OA模型,造模后分为模型对照组,25%及5%当归治疗组,0.5%及0.1%阿魏酸钠治疗组,另取8只大鼠作正常对照;各组关节腔注射相应浓度药物或生理盐水0.1ml,3日一次;6周后检测血浆、关节液SOD、MDA,关节软骨取材光镜观察,检测软骨MMP-1、TIMP-1、Bcl-2、Bax的表达。[结果]25%当归和0.5%阿魏酸钠可增加血浆、关节液SOD活性(均P<0.05)并降低其MDA水平(均P<0.01);降低关节软骨Mankin’s评分(均P<0.01),降低软骨细胞MMP-1、Bax的表达(P<0.05或P<0.01),同时使TIMP-1、Bcl-2的表达增加(P<0.05或P<0.01);5%当归无显著效果,0.1%阿魏酸钠对部分检测指标有统计意义。[结论]当归、阿魏酸钠关节腔注射治疗大鼠OA均有疗效,其作用具有剂量依赖性,阿魏酸是当归注射液治疗OA的有效单体成分。
