Osteoarthritis is a chronic degenerative articular disorder. Formation of bone spurs, synovial inflammation, loss of cartilage, and underlying bone restructuring have been reported to be the main pathologic characteristics of osteoarthritis symptoms. The onset and progression of osteoarthritis are attributed to various inflammatory cytokines in joint tissues and fluids that are produced by chondrocytes and/or interact with chondrocytes, as well as to low-grade inflammation in intra-articular tissues. Disruption of the equilibrium between the synthesis and degradation of the cartilage of the joint is the major cause of osteoarthritis. Hence, developing a promising pharmacological tool to restore the equilibrium between the synthesis and degradation of osteoarthritic joint cartilage can be a useful strategy for effectively managing osteoarthritis. In this review, we provide an overview of the research results pertaining to the search for a novel candidate agent for osteoarthritis management via restoration of the equilibrium between cartilage synthesis and degradation. We especially focused on investigations of medicinal plants and natural products derived from them to shed light on the potential pharmacotherapy of osteoarthritis.

Adhesive capsulitis of the shoulder joint is a common disease characterized by pain at the insertional area of the deltoid muscle and decreased range of motion. The pathophysiological process involves fibrous inflammation of the capsule and intraarticular adhesion of synovial folds leading to capsular thickening and contracture. Regarding the multidirectional limitation of motion, a limitation in external rotation is especially prominent, which is related to not only global fibrosis but also to a localized tightness of the anterior capsule. Ultrasound and magnetic resonance imaging studies can be applied to rule out other structural lesions in the diagnosis of adhesive capsulitis. Hydraulic distension of the shoulder joint capsule provides pain relief and an immediate improvement in range of motion by directly expanding the capsule along with the infusion of steroids. However, the optimal technique for hydraulic distension is still a matter of controversy, with regards to the infusion volume and rupture of the capsule. By monitoring the real-time pressure-volume profile during hydraulic distension, the largest possible fluid volume can be infused without rupturing the capsule. The improvement in clinical outcomes is shown to be greater in capsule-preserved hydraulic distension than in capsule-ruptured distension. Moreover, repeated distension is possible, which provides additional clinical improvement. Capsule-preserved hydraulic distension with maximal volume is suggested to be an efficacious treatment option for persistent adhesive capsulitis.

Phytoceramide (Pcer) is found mainly in plants and yeast. It can be neuroprotective and immunostimulatory on various cell types. In this study, the therapeutic effect of Pcer was explored using the carrageenan/kaolin (C/K)-induced arthritis rat model and fibroblast-like synoviocytes (FLS). Pcer treatment (1, 10, and 30 mg/kg/day) were given to the arthritic rats for 6 days after disease induction. Weight distribution ration (WDR), knee thickness, squeaking score, serum levels of proinflammatory mediators, and histological analysis were measured and performed to evaluate arthritic symptoms in the rat model. In interleukin (IL)-1β-stimulated FLS, proinflammatory mediators were measured after Pcer (1-30 µM) treatment. Arthritic symptoms in rats with Pcer treatment were significantly decreased at days 4 to 6 after C/K arthritis induction. Inflammation in the knee joints were also significantly decreased in rats with Pcer treatment. Furthermore, in IL-1β-stimulated FLS, the expressions of proinflammatory mediators were also inhibited by Pcer. As shown by the results, Pcer has anti-arthritic effects in the C/K rat model and in synovial cells, suggesting that Pcer has the potential to be a useful agent in arthritis treatment.

Phospholipase A$_{2}$ (PLA$_{2}$) is lipolytic enzyme that has known to be involved in inflammation. In the course of our screening for antiinflammatory compounds from natural products, a compound having PLA$_{2}$ inhibitory activities was isolated from the methanol extract of Umbilicaria esculenta. The compound was identified as lecanoric acid based on various NMR studies including DEPT, HETERO-COSY and HMBC experiments. Lecanoric acid inhibited human rheumatoid synovial PLA$_{2}$ activity with IC$_{50}$ of 0.17 mM and also exhibited antitumor activity (ED$_{50}$=2.7 $\mu $g/ml) against skin tumor cell line (LOX-IMVI).

With an aim of obtaining high efficacy in cartilage regeneration, implantable polymeric rods were fabricated. These rod-type matrices were anticipated to perform structural tissue supporting activity and enhance extracellular matrix (ECM) formation by releasing specific agent, DHEA-S, in controlled manner. It is expected that application for the drilling operation on the articular cartilage of OA patients as the implants may promote regeneration of their cartilage. Osteoarthritis (OA) is a degenerative joint disease characterized by progressive loss of articular cartilage, subchondral bone remodeling, spur formation, and synovial inflammation. (omitted)

To evaluate effect of CYTG on inhibiting the occurrence of arthritis, we performed the experiments including production of inflammatory cytokine and immunoglobulin in collagen arthritis model. The results were obtained as fellows. CYTG group showed inhibitory effect on arthritis incidence than control group for four weeks. Arthritis index of CYTG group reduced compared with control group. In CYTG group, production of cytokines which show suppressive effect on inflammation(IL-2, COX-2) was increased and which promotes inflammation(IL-10) was decreases in spleen. In CYTG group, production of immunoglobulin (IgG-RF) was reduced compared with control, and rate of CD3+CD69+T cell is lower in lymph node and CD4+CD25+ T cell is higher in lymph node and spleen. And synovial infiltration in the knee were observed in the controls (PBS-treated mice), whereas CYTG-treated mice exhibited significantly reduced histologic evidence of destruction and inflammation. So, the histopathological scoring average of CYTG group was 2.5 compared with control group(CIA mice) 4.5. It was thought that our data express high effect via immune system specially through the controling the inflammatory cytokines and immunoglobulins. CYTG could be usefully applied for the prevention and treatment of RA, and also is expected to be clinically helpful on the treatment of RA through modification.

Objectives: This study was carried out to find the effects of Changchuldoin-tanggamibang (hereinafter referred to CDIT) on the inhibition of arthritis induced by collagen on DBA/1J mouse. Methods: The experimental mice were divided into four groups: normal group (Nr), control group (CIA-CT), methotrexate group (CIA-MTX), and Changchuldoin-tanggamibang group (CIA-CDIT). Cytotoxicity, hepatotoxicity, arthritis index, value of immunocytes in draining lymph node and paw joint, and rheumatoid factor (IgG, IgM) in serum were measured in vivo. Results: 1. Cytotoxicity against hFCs was not shown in any concentration. 2. Hepatotoxicity was low in the CDIT-treated group compared with the MTX group. 3. The arthritis index decreased significantly. 4. In total cell counts of DLN and paw joint, the cells in DLN increased significantly while there was a significant decrease in paw joint. 5. In lymph nodes, CD19+, CD3+, CD4+, CD8+, CD3+/CD8+, CD3+/CD69+, CD4+/CD25+, CD3+/CD49b+, and CD4+/CD44+ cells increased significantly, while B220+/CD23+, and CD11c+/MHCII+ cells decreased significantly. 6. In joints, CD3+, CD4+, CD4+/CD25+, and CD11b+/Gr-1+ cells decreased significantly. 7. The level of IgG decreased and the level of IgM significantly decreased compared with the control. 8. Anti-collagen II in serum decreased compared with the control. 9. Around the joint of the CDIT group, infiltration of inflammation, synovial hyperplasia, invasion of cytokine, of cartilage, deposition of collagen and synovial injury decreased compared with the control in histopathologic observation (HE, MT staining). Conclusions: Comparison of the results for this study showed that CDIT had immunomodulatory effects. We expect that CDIT could be used as a effective drug for not only rheumatoid arthritis but also another auto-immune diseases. Therefore, we have to survey continuously, looking for effective substances and mechanisms in the future.
