摘 要 目的:考察乌头注射液对膝关节骨性关节炎(KOA)模型兔体内软骨寡聚基质蛋白(COMP)、抑癌基因p53编码蛋白(p53
蛋白)、骨形成蛋白2(BMP-2)等因子的影响,探讨该注射液治疗KOA的作用机制。方法:将24只兔随机分为空白组、模型组、玻

ABSTRACT OBJECTIVE:To investigate the effects of Aconitum injection on cartilage oligomeric matrix protein(COMP),
encoded protein by tumor suppressor gene p53(p53 protein)and bone morphogenetic protein 2(BMP-2)in knee osteoarthritis
(KOA)model rabbit,so as to explore the mechanism of the injection in the treatment of KOA. METHODS:Totally 24 rabbits
were randomly divided into blank group,model group,Sodium hyaluronate group and Aconitum injection group,with 6 rabbits in
each group. KOA model was established by injecting 2% papain-0.03 mol/L L-cysteine solution into the articular cavity of rabbits in
model group,sodium hyaluronate group and Aconitum injection group at the 1st,4th and 7th day,respectively,except the blank
group. At the 1st,4th and 7th day after modeling succeeded,0.1 mL/kg of normal saline,Sodium hyaluronate injection and
Aconitum injection were injected into the articular cavity of rabbits,respectively. The cartilage tissue of knee joint was taken from
above 4 groups,and the contents of COMP and p53 protein were detected by ELISA. The cartilage morphology of rabbit knee joint
was observed by naked eye. The cartilage of the knee joint was collected and stained by HE staining,and then the histomorphology
changes were observed by light microscope;Mankin scoring was conducted. The two-step method of PV was used to make the
immunohistochemical specimens of knee joint cartilage,and the relative expression of BMP-2 was detected. RESULTS:Compared
with blank group,the edge of cartilage was damaged and the cartilage surface was damaged in the model group. The results of
histomorphology observation showed that the joint tissue structure was obviously irregular,the distribution of chondrocytes was
disordered with morphological changes,and the Mankin score was significantly increased(P<0.05);the contents of COMP and
