Objectives: This study was carried out to investigate the effects of Buja-tang treatment on the early change of the monosodium iodoacetate-induced osteoarthritis in rats.
Methods: Arthritis was induced by injection of monosodium iodoacetate(MIA)(0.25 mg) into both knee joint cavities of rats. Arthritic rats were divided into control(n=8) and treated(n=8) group. The control group was taken distilled water and the treated group, extracts of Buja-tang by orally for 20 days. At the end of the experiment(20 days after MIA injection), gross and histopathological examinations on the articular structures of knee joints were performed. Proteoglycan(PG) content in articular cartilages was analyzed by safranine O staining method. And also, tumor necrosis factor-α(TNF-α) and interleukin-1β(IL-1β) contents in synovial fluid were measured by enzyme-linked immunosorbent assay(ELISA) method.
Results: 1. Body weight(g) of the treated group was increased significantly compared with control group at 15 and 20 days after injection. 2. Grossly, the degree of osteoarthritis in the treated group was alleviated compared with the control group. 3. PG content in articular cartilage of the treated group was increased significantly compared with the control group. 4. Histopathologically, osteoarthritic score of the treated group was decreased significantly compared with the control group. 5. TNF-α content in synovial fluid of the treated group was decreased significantly compared with the control group.
Conclusions: On the basis of these results, we suggest that Buja-tang have inhibiting effects on the progression of arthritis in MIA-induced osteoarthritis model. And it is related to inhibiting the activity of TNF-α in osteoarthritic chodrocytes and synovial membranes.
