【摘要】：目的比較木瓜蛋白酶關節(jié)腔注射與關節(jié)石膏伸直位制動建立兔膝骨關節(jié)炎模型的效果。方法將21只實驗兔采用隨機區(qū)組分組法分為正常組、木瓜蛋白酶組及石膏組,每組7只。木瓜蛋白酶組予6%木瓜蛋白酶生理鹽水溶液于實驗開始第1、4、7天行右膝關節(jié)腔注射,注射結(jié)束4周后造模完成;石膏組予膝關節(jié)伸直位固定6周;記錄實驗期間動物不良情況發(fā)生率,造模完成后處死實驗兔,取軟骨標本進行大體觀察、Pelletier評分、Mankin's評分,免疫組化測定軟骨Ⅱ型膠原蛋白含量,ELISA法檢測血清和關節(jié)液中腫瘤壞死因子-α(TNF-α)、軟骨寡聚基質(zhì)蛋白(COMP)以及基質(zhì)金屬蛋白酶-3(MMP-3)的含量。結(jié)果大體觀察顯示木瓜蛋白酶組與石膏組均出現(xiàn)關節(jié)腫脹、關節(jié)間隙變窄、軟骨缺損、滑膜增生硬化、炎癥改變、骨贅形成;Pelletier評分、Mankin's評分、Ⅱ型膠原蛋白含量、血清和關節(jié)液中TNF-α、COMP以及MMP-3的含量,木瓜蛋白酶組、石膏組與正常組比較,差異均有統(tǒng)計學意義(P0.05);木瓜蛋白酶組與石膏組比較,上述指標差異均無統(tǒng)計學意義(P0.05)。木瓜蛋白酶組動物不良情況發(fā)生率明顯低于石膏組,差異有統(tǒng)計學意義(P0.01)。結(jié)論木瓜蛋白酶關節(jié)腔注射與石膏關節(jié)伸直位制動均能成功建立膝骨關節(jié)炎模型,但木瓜蛋白酶關節(jié)腔注射法更為快捷、簡便,并發(fā)情況少,可行性好。
[Abstract]:Objective to compare the effect of papain injection and plaster immobilization on rabbit knee osteoarthritis model. Methods 21 rabbits were randomly divided into normal group, papain group and gypsum group with 7 rabbits in each group. In the papain group, 6% papain saline solution was injected into the right knee joint on the 1st and 4th day of the experiment, and the model was made after 4 weeks of injection, while the gypsum group was fixed in the straight position of the knee joint for 6 weeks. The incidence of adverse animal conditions during the experiment was recorded. After the model was made, the rabbits were killed, and the cartilage samples were taken for general observation, Pelletier score, Mankin's score, and so on. The content of collagen 鈪，
