Abstract

Objectives : This study was to investigate the effects of GCP treatment on the monosodium iodoacetate-induced osteoarthritis in rats. Methods : Arthritis was induced by injection of Monosodium lodoacetate(0.5mg) into knee joints of rats. Arthritic rats were divided into control(n=8) and treated(n=8) group. Control group was taken distilled water for 20 days. Treated group was taken extracts of GCP by oraly for same duration. Normal group(n=8) was injected with normal saline and was taken distilled water for 20 days. Body weight was measured at 0, 5, 10, 15, 20 days after injection. Macroscopic examination and histopathological study on articular cartilage of knee joint were operated at 20 days after injection. Proteoglycan(PG) content of articular cartilages of knee joint was represented by safranine O staining, was measured at 20 days injection. Tumor necrosis $factor-{\alpha}$, $Interleukin-1{\beta}$, Interleukin-6 in synovial fluid were measured with ELISA kit at 20 days after injection. Immunohistochemical staining of COX-2, iNOS in knee joints were observed at 20 days after injection. Results : 1. Body weight of the treated group increased compare with control group at 20 days after injection. 2. Macroscopically, degree of osteoarthritis in the treated group were evaluated compared with the control group. 3. PG content in articular cartilage of the treated group was significantly increased compared with the control group. 4. Histopathologically, osteoarthritic scores of the treated group was significantly decreased compared with the control group. 5. $TNF-{\alpha}$ content in synovial fluid of the treated group was decreased compared with the control group. 6. $IL-1{\beta}$ content in synovial fluid of the treated group was significantly decreased compared with the control group. 7. Positive reaction of COX-2 in chondrocytes and synovial membrane of the treated group was faint compared with the control group. Conclusions : On the basis of these results, we concluded that GCP has inhibiting effects on the $IL-1{\beta}$ and COX-2 secretion of chondrocytes and synovial membrane in Monosodium lodoacetate-Induced osteoarthritis model of rats.
