Abstract:

BACKGROUND: Type Ⅱ collagen and chondroitin sulfate are the major components of articular cartilage. They cannot only protect the cartilage, but also inhibit pathology of osteoarthritis.
OBJECTIVE: To evaluate the curative effect of type Ⅱ collagen injection and type Ⅱ collagen- chondroitin sulfate composite injection on osteoarthritis by detecting the expression of rheumatoid factor and C-reactive protein.
METHODS: A rat model of knee osteoarthritis was established by using improved Hulth’s method. The treatment was performed via injection into the articular cavity (treatment group A: type Ⅱ collagen injection; treatment group B: type Ⅱ collagen-chondroitin sulfate composite injection; positive control: sodium hyaluronate; model control: physiological saline). After operation, rats in each group were characterized with daily observation, weighing, serum antibody test and histological observation.
RESULTS AND CONCLUSION: After treatment, the content of rheumatoid factor and C-reactive protein in rats’ serum of model group was increased, and inflammation was aggravated; while compared with the model group, the content of rheumatoid factor and C-reactive protein in the other groups, especially in the treatment group B, were lower and the inflammation was eased (P < 0.01). The findings show that both type Ⅱ collagen and sodium hyaluronate can prevent and treat osteoarthritis effectively. The therapeutic effect of type Ⅱ collagen combined with chondroitin sulfate is better.
