采用在兔膝关节内注入木瓜蛋白酶造成的膝关节退行性改变模型,考察关节腔内长期多次注射玻璃酸钠对这种退行性改变的抑制和改善作用。结果表明:玻璃酸钠对已造成退行性改变的关节软骨有减轻和改善其病变程度的作用。
The knee joint degeneration model induced by papain injection in rabbit knee joint was used to investigate the inhibitory and ameliorative effects of sodium hyaluronate injection on the degenerative changes in the joint cavity. The results showed that sodium hyaluronate can reduce and improve the degree of lesion in articular cartilage which has caused degenerative changes.
