Objectives The purpose of this study was to know the effects of Danggwisayeok-tang (Dangguisinitang) extract (DGSYT) on monosodium iodoacetate (MIA)-induced rat osteoarthritis. Methods For this purpose, rats were divided into 5 groups. Normal group was not injected with MIA and orally administered any medication. Control group was injected with MIA and not orally administered any medication. DGSYT100 group was injected with MIA and orally administered 100 mg/kg of DGSYT. DGSYT300 group was injected with MIA and orally administered 300 mg/kg of DGSYT. JoinsT group was injected with MIA and orally administered 20 mg/kg of Joins tablet. DGSYT100 and DGSYT300 groups were orally administered DGSYT during a week before and 3 weeks after based on the day MIA injected. The changes of hepatotoxicity, nephrotoxicity, relative hind paw weight distribution, cytokine in serum, cytokine messenger ribonucleic acid (mRNA) in joint tissue and histopathological observation (Hematoxylin & Eosin and Safranin-O staining) were measured. Results Alanine aminotransferase (ALT) levels of DGSYT100, DGSYT300 and JoinsT groups were increased significantly, but these results were within normal range. Aspartate aminotransferase (AST) and creatinine levels of all groups were not changed significantly. In the change of relative hind paw weight distribution, DGSYT300 and JoinsT groups were decreased significantly 14 and 21 days after MIA injected. Interleukin-$1{\beta}$ (IL-$1{\beta}$) and Interleukin-6 (IL-6), Leukotriene $B_4$ and Osteocalcin levels of DGSYT300 and JoinsT groups were decreased significantly. In measurement of IL-$1{\beta}$ and nitric oxide synthase-II mRNA relative quantitative of control, DGSYT100, DGSYT300 and JoinsT groups were decreased significantly. In measurement of TNF-${\alpha}$, IL-6 and Cyclooxygenase-2 mRNA relative quantitative of control, DGSYT300 and JoinsT groups was decreased significantly. In histopathological observation of knee, synovial tissue, cartilage and proteoglycan of DGSYT100, DGSYT300 and JoinsT were well preserved compared with control group. Conclusions According to the results, DGSYT has anti-inflammation and pain relief effects. So it should be suppressed progression of arthritis in MIA-induced osteoarthritis rat.

The present study was conducted to evaluate the anti-inflammatory and anti-arthritic effects of fermented Achyranthes japonica (Miq.) Nakai extract (FAJE). The FAJE was effective in nitrogen oxide (NO) scavenging in RAW264.7 cells. In the case of experimental Sprague Dawley (SD) rats injected with monosodium iodoacetate (MIA), the levels of $TNF-{\alpha}$ and $IL-1{\beta}$ in blood increased in the osteoarthritis-induced group while decreasing in the group administered with FAJE. In addition, MMP-2 and MMP-9 in cartilage tissues increased in the osteoarthritis-induced group, but decreased in the group treated with FAJE. Cartilage examination indicated that the osteoarthritis-induced group exhibited cartilage erosion and cell degeneration, but in the FAJE administered group the tissue, conditions were recovered and cartilage proteoglycan was increased. Therefore, FAJE clearly showed anti-inflammatory effects and this suggests it is effective for recovery from osteoarthritis induced by MIA.

Purpose: This study was performed to investigate the effect of joint mobilization on pain relief and cartilage repair in an induced osteoarthritis rat model by analyzing the expression of heat shock protein 70 in articular cartilage. Methods: MIA was injected into SD rats to induce osteoarthritis. These rats were divided into 4 groups: control group (n=30), no further treatment after the MIA injection ; experimental group I(n=30), performed swimming exercise after the MIA injection experimental group II (n=30), underwent joint mobilization after the MIA injection and experimental group III (n=30), performed swimming exercise and underwent joint mobilization after the MIA injection. For the histologic and pathophysiologic evaluation, safranin-O staining and for the immunohistochemical evaluation, the expression of HSP 70 in articular cartilage was analyzed 1, 7, 14, and 21 days after the MIA injection. Results: The inflammatory response and loss of tissue declined in experimental groups I and II over time, whereas the greatest decreases were noted in experimental group III. In the articular cartilage, low expression of HSP 70 was observed in every group on day 1, whereas HSP 70 expression was elevated on days 7 and 14 in experimental groups II and III. After 21 days, experimental group II displayed the strongest positive reaction, whereas HSP 70 was higher in experimental group III at this time point compared to that after 14 days. Conclusion: Our results showed that swimming exercise and joint mobilization had positive effects on pain relief and histologic and functional recovery in an induced osteoarthritis rat model.

Objectives Bogol-tang has clinically been used to protect joint cartilage and to treat osteoarthritis. Our objective was to study the protective effect of Bogol-tang extract (BGT) in functional impairment, behavioral disorders, cartilage loss and pathological changes in a monoiodoacetate (MIA)-induced murine osteoarthritis (OA) model and interleukin (IL)-$1{\beta}$ -treated primary rat chondrocytes. Methods Mouse knee joints were injected with MIA, a chemical that inhibits glycolysis and causes joint inflammation and matrix loss. MIA-OA induced mice orally administered BGT or acetaminophen (AAP) for 18 days by daily. Primary rat chondrocytes were pretreated with BGT or dexamethasone (DEX) and followed by co-incubation with IL-$1{\beta}$ (10 ng/mL). Results In MIA-OA mice model, BGT led to delayed response on hot plate analysis, and suppressed the cartilage loss and damages in joint tissues. BGT suppressed the elevated levels of inflammatory mediators, nitrite and $PGE_2$, the gene expression of matrix degrading enzymes, and extracellular-signal-regulated kinases 1/2 and c-JunN-terminal kinase phosphorylation in IL-$1{\beta}$-treated primary rat chondrocytes. Conclusions Our results suggest that BGT improve the knee joint function and delay the cartilage damages by anti-nociceptive, anti-inflammatory and ant-catabolic effects, which indicate BGT could be a potential candidate for osteoarthritis treatment.

Purpose: The aim of this study was to investigate the anti-osteoarthritic effect of the ethanol extract of Boswellia serrata gum resin (FJH-UBS) enriched with keto-β-boswellic acid and 3-O-acetyl-11-keto-β-boswellic acid compared to the conventional Boswellia serrata extract by adding the process of removing oil with hexane, in the monosodium iodoacetate (MIA)-induced osteoarthritis rat model. Methods: Sprague-Dawley (SD) rats were orally administered 0, 40, or 80 mg of FJH-UBS/kg body weight (BW)/day for 5 weeks and injected with MIA intra-articularly into right knee joints on day 15 to induce osteoarthritis. Changes in the knee joint microarchitecture, cartilage degradation, the expression of inflammatory mediators, cytokines, and matrix metalloproteinases (MMPs) in serum and synovia were observed. Results: Oral administration of FJH-UBS (80 mg/kg BW/day) reduced MIA-induced knee swelling and cartilage degradation and increased the expression of type II collagen and aggrecan in articular cartilage. Furthermore, FJH-UBS administration reduced MIA-induced increases in the serum levels of prostaglandin E2, leukotriene B4, interleukin (IL)-1β, IL-6, and MMP-13, and MIA-induced increases in the mRNA expressions of inducible nitric oxide synthase, cyclooxygenase-2, 5-lipoxygenase, IL-1β, IL-6, TNF-α, MMP-2, MMP-9, and MMP-13 in the synovia of knee joints. Conclusion: These results indicate that FJH-UBS exerts its anti-osteoarthritic effects by suppressing the expressions of inflammatory cytokines and MMPs and, thus, cartilage degradation. Furthermore, they suggest that FJH-UBS has potential use as a functional food that improves joint and cartilage health.

Objectives : The aim of this study was to investigate the protective effects of an aqueous extract from Taxillus chinensis (DC.) Danser (TCE) in Monosodium iodoacetate (MIA)-induced osteoarthritis (OA) rat model. Methods : Sprague Dawley male rats were divided into the following four groups (n=6 per group): Normal (saline control), MIA (MIA-induced OA with vehicle), TCE (MIA-induced with TCE treatment), and IM (MIA-induced with indomethacin treatment). Rats in which OA was induced by MIA were treated with TCE (200 mg/kg) or indomethacin (1 mg/kg) for 4 weeks. Weight-bearing on the hind legs and body weights were measured weekly. At the end of the experiment (3 weeks after MIA injection), serum aspartate aminotransferase and alanine aminotransferase levels were measured to assess the liver toxicity induced by TCE. Its effects on serum inflammatory cytokine levels and tissue histopathology were also evaluated. Results : TCE restored the hind limb weight-bearing distribution. Serum levels of Interleukin 6 (IL-6), Tumor necrosis factor alpha (TNF-${\alpha}$) and Leukotriene B4 (LTB4) were significantly higher in the MIA group than in the Normal group, but serum IL-6 levels were significantly lower in the TCE group. In the TCE group, the synovial membrane was protected in hematoxylin and eosin and Safranin-O staining, respectively. Conclusions : TCE recovered the hind paw weight bearing distribution, inhibited the production of inflammatory cytokine, and protected synovial tissue and cartilage in the OA rat model. Therefore, TCE appears to be an effective therapeutic agent for treating OA and OA-related symptoms.

Objectives : This study was planned to evaluate the therapeutic effectiveness and possible underlying mechanism of TPE (Tetrapanax papyrifer stem(inner part of the stem Extract) and AQE (Akebiae quinata stem Extract) on osteoarthritis. Methods : Osteoarthritis models were induced through intra-articular injection of MIA (monosodium iodoacetate) 50 μL with 80 mg/ml in rats. Excluding the normal group, Osteoarthritis-induced rats were divided into 4 groups (Control, INDO, TPE, AQE). The drug concentrations were indomethacin 5 mg/kg, TPE 200 mg/kg, and AQE 200 mg/kg, and were orally administered once a day for a couple of weeks. After drug supplementation, the effects of TPE and AQE were measured with serum diagnosis, western blotting, and histopathological staining. Results : It was found that the DPPH and ABTS free radical erasure ability of AQE was better than that of TPE. AQE administration improved rear limb overload and it led to relieving pain. Both PTE and AQE significantly reduced the expression of inflammatory mediators COX-2, iNOS, and inflammatory cytokine IL-1β and IL-6 by inhibiting the phosphorylation of IκBα and deactivating the pathway of NF-κBp65. On the other hand, TNF-α was significantly reduced only by administration of AQE. In addition, histopathological analysis showed that the administration of AQE compared to PTE suppressed cartilage degeneration and effectively suppressed damage to proteoglycan, a component of ECM. Conclusion : Reviewing these experimental results, TPE and AQE possessed the effect of delaying the progress of osteoarthritis and protecting cartilage. In addition, the results of this study show that AQE has a better cartilage protection effect than TPE.

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-$\alpha$($TNF-{\alpha}$) and interleukin-$1{\beta}$($IL-1{\beta}$) 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. $TNF-{\alpha}$ 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 $TNF-{\alpha}$ in osteoarthritic chodrocytes and synovial membranes.
