从胫骨平台的3个部位(骨关节炎病变中心、病变边缘和远端部位)采集49份人软骨标本,并采用Mankin评分标准进行组织学分级。将组织匀浆并离心,以获得不溶性沉淀。将其重悬于缓冲液中并在37°C,pH 7.5下孵育。通过释放含羟脯氨酸的肽定量胶原蛋白消化。最高的胶原溶解活性(4.6%)被发现在病变的中心,在偏远的网站下降到2.4%和对照组的1.1%。6-9级的中度严重疾病具有最高的胶原溶解活性。大约55%的金属依赖性胶原蛋白溶解活性为潜伏形式,可被醋酸氨基苯汞激活;其余为自激活。建立了一种从软骨中提取胶原酶的方法,提取的胶原酶产生典型的I型胶原75:25裂解产物。
Forty‐nine specimens of human cartilage were taken from 3 sites on the tibial plateau (center of osteoarthritic lesion, edge of lesion, and remote site) and graded histologically by the scale of Mankin.The tissue was homogenized and centrifuged to obtain an insoluble pellet. This was resuspended in buffer and incubated at 37°C, pH 7.5. Collagen digestion was quantitated by the release of hydroxyproline‐containing peptides. The highest collagenolytic activity (4.6%) was found in the center of lesions, declining in remote sites to 2.4% and in controls to 1.1%. Moderately severe disease of grade 6–9 had the highest collagenolytic activity. Approximately 55% of the metal‐dependent collagenolytic activity was in a latent form, activatable by amino‐phenylmercuric acetate; the remainder was self‐active. A method was developed for the extraction of collagenase from cartilage; the extracted enzyme produced the typical75:25 cleavage products of type I collagen.
