'检测突出和非突出椎间盘中是否有肉芽组织形成以及基质金属蛋白酶-1、3的表达,并分析酶活性与肉芽组织和椎间盘突出类型之间的关系.52个椎间盘(12个非突出,40个突出)标本分别用HE染色以检测肉芽组织的数量,以及链酶亲和素-生物素复合物(SABC、Strep': [1], 'Avitin-Biotin': [2], 'Conplex)加MMP-1和MMP-3单克隆抗体染色以检测MMP-1和MMP-3的表达.结果在经韧带型脱出和游离型标本中普遍有包含巨噬细胞,纤维母细胞及毛细血管的肉芽组织存在.而在凸出及韧带下突出型标本中很少见,在非突出型标本中,无肉芽组织表达.在肉芽组织中的大部分细胞和软骨细胞(纤维环和髓核)有明显的染色阳性的MMP-1和MMP-3的表达.突出组织中的MMP-1和MMP-3含量较非突出组织中的含量明显增高(P<0.01),游离型和经韧带型脱出标本中的MMP-1和MMP-3的表达较韧带下脱出和凸出型增高(P<0.05).MMP-1、MMP-3可能与椎间盘退变及突出等病理改变有关.在突出椎间盘中,与肉芽组织炎性细胞有关的MMP-1、MMP-3的阳性表达,提示这些蛋白酶与组织降解造成的椎间盘病理改变有关系。':
