This study was to investigate the effects of Gyeonbi-Tang Treatment on the monosodium iodoacetate(MIA)-induced mild osteoarthritis in rats. Arthritis was induced by injection of MIA(0.25 mg) into knee joints of rats. Arthritic rats were divided into control(n=8) and treated(n=8) group. Control group was taken distilled water and treated group was taken extracts of Gyeonbi-Tang by orally for 20days. Body weights were measured at 0, 5, 10, 15, 20 days after MIA injection. At the end of experiment(20day after MIA injection), gross and histopathological examination on the articular structures of knee joints were performed. Proteoglycan(PG) contents in articular cartilages were analysed. And also, tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) and interleukin-1${\beta}$(IL-1${\beta}$) contents in synovial fluids were measured by ELISA method. Body weights of the treated group were significantly increased compared with control group at 15, 20 days after injection. Grossly, the severity of osteoarthritis in the treated group were alleviated compared with control group. PG contents in articular cartilages of the treated group were increased compared with control group. Histopathologically, osteoarthritic scores of the treated group was decreased compared with the control group. TNF-${\alpha}$ contents in synovial fluids of the treated group were significantly decreased compared with control group. On the basis of these results, we concluded that Gyeonbi-Tang Treatment has anti-arthritic effects on the monosodium iodoacetate-induced mild osteoarthritis in rats. And it's effects were related with reduced secretion of TNF-${\alpha}$ from synovial membranes.

Background: Ginsenoside Rb1 (G-Rb1), one of the major active compounds in Panax ginseng, has already been shown to reduce inflammation in various diseases. Osteoarthritis (OA) has traditionally been considered a degenerative disease with degradation of joint articular cartilage. However, recent studies have shown the association of inflammation with OA. In the present study, we investigated whether Rb1 had an antiinflammatory effect on monoiodoacetate (MIA)-induced OA in ovariectomized rats as a model of postmenopausal arthritis. Methods: G-Rb1 at a dosage of 3 and 10 ㎍/kg body weight was administered every 3 days intraarticularly for a period of 4 weeks to observe antiarthritic effects. Diclofenac (10 mg/kg) served as a positive control. Results: The administration of Rb1 significantly ameliorated OA inflammatory symptoms and reduced serum levels of inflammatory cytokines. Furthermore, G-Rb1 administration considerably enhanced the expression of bone morphogenetic protein-2 and collagen 2A and reduced the levels of matrix metalloproteinase-13 genes, indicating a chondroprotective effect of G-Rb1. G-Rb1 also significantly reduced the expression of several inflammatory cytokines/chemokines (interferon gamma (IFN-γ), monocyte chemoattractant protein-1 (MCP-1)/CCL-2, interleukin [IL]-1β, and IL-6). Histological analysis demonstrated that G-Rb1 significantly attenuated the pathological changes in MIA-induced OA in ovariectomized rats. Safranin O and toluidine blue staining further demonstrated that G-Rb1 effectively prevented the degradation of cartilage and glycosaminoglycans, respectively. Conclusion: Overall, our results suggest that G-Rb1 exerts cartilage protective effect on MIA-induced ovariectomized OA rats, by inhibiting inflammatory mediators such as IL-6, IL-1β, MCP-1/CCL-2, cyclooxygenase-2 (COX-2), and prostaglandin E₂ (PGE2). These results shed a light on possible therapeutic application of G-Rb1 in OA.

본 연구에서는 오디추출복합물(mulberry extract complex, MEC)의 퇴행성관절염 증상 완화 및 개선 효과 가능성을 탐색하기 위하여 monosodium iodoacetate(MIA)로 유도한 퇴행성관절염 in vivo 실험모델을 이용하였다. 연골의 주요 구성성분인 glycosaminoglycan(GAG) 및 collagen의 농도를 실험동물의 연골에서 측정한 결과 MIA로 인해 감소하였던 GAG 및 collagen의 농도가 MEC를 경구 투여한 실험군에서 농도 의존적으로 증가하였다. 또한 교원질 합성을 억제하고 분해를 촉진하는 matrix metalloproteinase-2, 9, 13의 농도를 측정한 결과는 MEC의 농도에 따라 감소하는 결과를 보여주었다. 연골 손상 지표인 cartilage oligomeric matrix protein과 C-terminal telopeptide 2의 측정결과에서는 대조군보다 유의성 있는 감소를 나타내어 MEC가 퇴행성관절염의 진행 억제에 도움을 줄 수 있을 것으로 생각된다. 관절염 지수 평가에서도 MEC는 모든 농도에서 대조군보다 유의성 있게 개선되는 결과를 나타내었다. 이상의 실험 결과를 통하여 MEC가 퇴행성관절염에서 나타나는 연골 구성성분의 분해를 억제하고, 여러 중요한 퇴행성관절염 진행 인자를 효과적으로 억제하여 결국 연골파괴 감소와 더불어 통증을 줄여줌으로써 퇴행성관절염에 대한 증상 완화 및 개선 효과가 있을 수 있는 건강기능식품의 원료로 활용될 수 있을 것으로 생각된다.

Objectives The anti-inflammatory and anti-arthritic effects of Youngseonjeatonguem (靈仙除痛飮, YSJTU) was evaluated in a cellular model using RAW264.7 macrophages, which are involved in osteoarthritis (OA), and an animal model using Sprague-Dawley (SD) rats, and a possible mechanism of anti-arthritic actions of YSJTU was presented. Methods RAW264.7 macrophages were activated by lipopolysaccharide (LPS). The production of pro-inflammatory cytokines (tumor necrosis factor [TNF]-𝛼, interleukin [IL]-1𝛽, and IL-6) and inflammatory mediators (nitric oxide [NO] and prostaglandin E2 [PGE2]) was determined by ELISA and Griess assay, respectively. Western blot was performed to determine inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression. OA was induced by intra-articular injection of monosodium iodoacetate (MIA) into the right knee joint of SD rats. Results In RAW264.7 macrophages, YSJTU reduced LPS-induced production of TNF-𝛼, IL-1𝛽, and IL-6. In addition, YSJTU inhibited LPS-induced production of NO and PGE2 by suppressing iNOS and COX-2 expression. In SD rats, YSJTU improved MIA-induced OA by reducing swelling, skin heat, and cartilage degradation. In addition, YSJTU reduced serum levels of TNF-𝛼, IL-1𝛽, and IL-6, along with its significant decrease in serum levels of NO and PGE2. Conclusions These results suggest that YSJTU may exert anti-arthritic effect, at least in part, by inhibiting macrophage-mediated joint inflammation.

Arthritis was induced by injection of MIA(0.5 mg) into knee joints of rats. Arthritic rats were divided into control(n=8) and treated(n=8) group. Control group was injected with normal saline once a day for 20 days, while treated group was injected with Bee-venom extract once a day for same duration. Body weights were measured at 0, 5, 10, 15, 20 days after injection. At the end of experiment, gross and histopathological examination on the articular cartilages of the knee joints were performed. Proteoglycan contents of articular cartilages were analysed by safranine O staining method. The contents of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 in synovial fluids were analysed by ELISA method. And also, COX-2 and iNOS immunohistochemical examination on the knee joints were performed. Body weights of the treated group were increased compared with control group at 20 days after injection. Grossly, the severity of osteoarthritis in the treated group were alleviated compared with control group. PG contents in articular cartilages of the treated group were significantly increased compared with control group. Histopathologically, degenerative and necrotic lesion of articular cartilages in the treated group were alleviated compared with those of the control group. $TNF-{\alpha}$ contents in synovial fluids of the treated group were decreased compared with control group. Positive reactions of COX-2 in chondrocytes and synovial membranes of the treated group were decreased compared with the control group. On the basis of these results, we concluded that Bee-venom treatment has anti-arthritic effects on the monosodium iodoacetate-induced osteoarthritis in rats. And it's effects were related with reduced secretion of $TNF-{\alpha}$ and COX-2 from osteoarthritic chondrocytes and synovial membranes.
