Objectives : The effects of water extract of deer antler herbal-acupunture solution(DHS), prepared from the pilose antler of Cervus korea TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immunosuppressive and immune-activating Korean herbal- acupuncture, on collagen-induced arthritis(CIA:RA model) in mice was studied. Destruction of cartilage and bone are hallmarks of human rheumatoid arthritis, and controlling these erosive processes is the most challenging objective in the treatment of RA. Methods : We investigated the tissue protective effects of deer antler treatment using established murine collagen-induced arthritis(CIA) as a model. Potential synergy of low dosages of anti-inflammatory glucocorticosteroids and deer antler was also evaluated. Results : Treatment of established murine CIA with deer antler herbal-acupunture solution(DHS) $(10-50{\mu}g/day)$ suppressed disease activity and protected against cartilage and bone destruction. Although $10-50{\mu}g/day$ DHS had only a moderate effect on the inflammatory component of the disease activity, it strongly reduced cartilage pathology, as determined by histological examination. Serum cartilage oligomeric matrix protein(COMP) levels were significantly reduced, confirming decreased cartilage involvement. Histological analysis showed that bone destruction was prevented. DHS administration increased serum IL-1Ra levels and reduced anticollagen type II antibody levels. Treatment with low-dose $DHS(1{\mu}g/day)$ was ineffective in suppressing disease score, serum COMP or joint destruction. Synergistic suppression of both arthritis oseverity and COMP levels was noted when low-dose DHS was combined with prednisolone(0.05mg/kg/day), however, which in itself was not effective. Conclusion : DHS was shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption. These results indicated that the DAS is not only highly stable and applicable to clinical uses in bone resorption, but also it will be served as a potent anti-inflammatory and anti-arthritic agents for treatment of human RA.

Objectives : The purpose of this study was find out the therapeutic effects of Ulmus davidiana Planch pharmacopuncture(UPP) on the mice with collagen-induced rheumatoid arthritis. Methods : UPP was prepared and tested for therapeutic potential of rhematoid arthritis by measuring the inhibition of cyc1ooxgenase-2(COX-2) and phospholipase A2(PLA2) activities in mice. Results : UPP showed therapeutic effects on collagen-induced rheumatoid arthritis on week 8 and week 9. UPP also inhibited Freund's complete adjuvant induced chronic rheumatoid arthritis in mice. UPP showed significant inhibition of type I and type II PLA2 activities in a dose dependent manner. However, PGE2 Production was not decreased with UPP and lipopolysaccharide-induced COX-2 protein expression was not inhibited by UPP. Conclusions : These results suggest that UPP has an therapeutic effects on drug induced-rheumatoic arthritis by inhibiting PLA2 activity.

Objectives : The purpose of this study is to evaluate effect of suppressing the expression of cyclo-oxygenase-type-2 (COX-2) as a consequence of inhibition macrophage migration inhibitory factor (MIF) activation by $Sambucus$ $williamsii$ $Hance$ (SWH) pharmacopunctureon rheumatoid arthritis (RA). Methods : In vitro test, synoviocytes extracted from type II collagen-induced arthritis (CIA) mouse's knee joint were cultivated After that, each well of synoviocytes was mixed with the extract of SWH at the dosage of $0.4mg/m{\ell}$, $0.6mg/m{\ell}$, $0.8mg/m{\ell}$, and $1.0mg/m{\ell}$ respectively, and cultivated for 24 hours after the addition. Reverse transcriptase - polymerase chain reaction (RT-PCR) is used to investigate the expression of MIF, Tumor necrosis factor (TNF)-${\alpha}$, COX-2 mRNA. $In$ $vivo$ test, thirty DBA female mice were used, and each ten mice were allocated into three group; normal group, CIA-elicitated group, and group treated with SWH pharmacopuncture on it's the point of $ST_{35}$ after CIA elicitation. It is investigated that change of mice foot thickness, histologic change of sliced synovial joint of mouse, and extent change of MIF, TNF-${\alpha}$, COX-2 in synovial membrane. Results : $In$ $vitro$ test, the expressions of cytokine(MIF, TNF-${\alpha}$, COX-2) mRNAs related to RA were dose-dependent decreased. In the SWH pharmacopuncture group, foot thickness and histologic change of sliced synovial joint were decreased comparing with CIA-elicitated group's change. In the SWH pharmacopuncture group, the suppression of MIF, TNF-${\alpha}$, COX-2 in synovial membrane was clearly shown comparing with CIA-elicitated group's change. Conclusions : It might be suggested that SWH pharmacopuncture mitigate tissue damage originated from rheumatoid arthritis by suppressing the expression of COX-2 as a consequence of inhibition MIF activation.

Objective: Since Ulmus davidiana Planch (Ulmaceae) has been known to have anti-inflammatory and protective effects on damaged tissue, inflammation and bone among other functions, this study was undertaken to address whether the water extract of the bark of Ulmus davidiana Planch (Ulmaceae) (UD) could modulate the expression of inducible inflammatory cytokines in mice. The present study was also done in order to assess the therapeutic effects of UD in collagen-induced arthritis (CIA) in mice. Methods : DBA/1 mice were immunized with bovine type II collagen. After a second collagen immunization, mice were treated with UD orally at 100 mg/kg once a day for 3 weeks. Paws were evaluated macroscopically for redness, swelling and deformities. The levels of $TNF-{\alpha}\;and\;IL-1{\beta}$ in the ankle were examined. The severity of arthritis within the knee joints was evaluated by histological assessment of cartilage destruction and pannus formation. Results : Administration of UD significantly suppressed the progression of CIA and inhibited the production of $TNF-{\alpha}\;and\;IL-1{\beta}$ in the paws. The erosion of cartilage was dramatically reduced in mouse knees after treatment with UD. In the serum of UD-treated mice, the levels of IL-4 and IL-10, anti-inflammatory cytokines, were increased. Conclusion : From the results, it was concluded that administration of UD has therapeutic effects on CIA including protection of cartilage and RA for a potential therapy.

OBJECTIVE: This study was Far infrared(FIR) irradiating to a rat collagen-induced autoimmune arthritis and observed nitric oxide level of spine. METHODS: Type II collagen(CII) in adjuvant was injected into rats on day 0. The results showed that rats injected with CII plus adjuvant had signs of autoimmune arthritis on day 14. Thereafter, Far infrared(FIR) irradiation was begun on day 15. The rats were irradiated FIR twice per day for 20 min each time. RESULTS: Seven days later(Day 22), the level of NO at FIR irradiated group(FRG; Arth+FIR) was decreased more than FIR-non irradiated group(FNRG; Arth). Twenty-one days later(Day 36), the level of NO at FRG was more closed to the control group's NO level than the FNRG. CONCLUSION: These results indicated that Far infrared irradiating appears to reduce the nitric oxide level at a rat model of autoimmune arthritis induced.

Mori Ramulus has multiple applications in Korean traditional medicine prescription because it has antioxidant and anti-inflammatory effects by reducing macrophage activities. Yet, no studies on the anti-arthritic activity of EMR (extract of Mori Ramulus) have been reported in vitro and in vivo. Rheumatoid arthritis (RA) is a systemic autoimmune disease with chronic inflammation characterized by hyperplasia of synovial cells in affected joints, which ultimately leads to the destruction of cartilage and bone. Because collagen-induced arthritis (CIA) is similar to RA in pathological symptoms and immune reactions, there have been several reports concerning RA using CIA mouse model. Here, we investigated the effects of Mori Ramulus on RA using CIA mice. The importance of CD4+ Th1 cells in RA progress was previously indicated and studies further showed that Th17 cells play a prime role in severity of disease. Accordingly, the present study was focused on CIA associated with CD4+ Th1 cells and Th1 7 cells. DBA/1OlaHsd mice were immunized with bovine type II collagen (CII). After a second collagen immunization, mice were treated with EMR once a day for 4 weeks. The severity of arthritis within the paw joints was evaluated by histological assessment of cartilage destruction and pannus formation. Immune cells in peripheral blood mononuclear cells (PBMC), draining lymph node (DLN) and paw joints, cytokine production and gene expression were assessed from CIA mouse using ELISA, FACS and real-time PCR analysis. Administration of EMR significantly suppressed the progression of CIA and inhibited the production of TNF-$\alpha$, IL-6 and IL-17 in the serum. The erosion of cartilage was dramatically reduced in mouse knees after treatment with EMR. In conclusion, our results demonstrate that EMR significantly suppressed the progression of CIA and that this action was mediated by the decreased production of TNF-$\alpha$, IL-6, IL-17 and collagen II-specific antibody in the serum. EMR suppressed Th17 cells and reduced level of IL-6 via B cell suppression, and thus, the levels of autoantibodies produced from B cells were decreased. Furthermore, EMR suppressed NKT cells which directly stimulate B cells and develop imbalance of Th1/Th2 cell. Oral administration of EMR (100 mg/kg or 200 mg/kg) significantly suppressed the progression of CIA, which is comparable to that of methotrexate (MTX, 0.3 mg/kg) used as a positive control. We are currently studying the mechanism underlying the therapeutic role for EMR in CIA mice.

The fruit of Terminalia chebula Retzius has been used as a panacea in India and Southeast Asia but its biological activities have not been fully elucidated. Here we report anti-arthritic and analgesic effect of NDI10218, a standardized ethanol extract of Terminalia chebula, on collagen-induced arthritis and acetic acid-induced writhing model, respectively. Arthritis was induced in DBA/1J mice by immunizing bovine type II collagen and mice were treated with NDI10218 daily for 5 weeks after the onset of the disease. NDI10218 reduced the arthritis index and blocked the synovial hyperplasia in a dose-dependent manner. The serum levels of pro-inflammatory cytokines TNF-${\alpha}$, IL-6, and IL-$1{\beta}$ were significantly reduced in mice treated with NDI10218. Production of the inflammatory IL-17, but not immunosuppressive IL-10, was also inhibited in splenocytes isolated from NDI10218-treated arthritis mice. Administration of NDI10218 markedly decreased the number of T cell subpopulations in the regional lymph nodes of the arthritis mice. Finally, NDI10218 reduced the number of abdominal contractions in acetic acid-induced writhing model, suggesting an analgesic effect of this extract. Taken together, these results suggest that NDI10218 can be a new therapeutic candidate for the treatment of rheumatoid arthritis.

Background: The treatment of rheumatoid arthritis still depend on conserve therapy in major. Recent studies report that n-3 polyunsaturated fatty acids(PUFA) could modulate the incidence and progress of arthritis. The purpose of this study was to investigate the effects of n-3 PUFA on the development of collagen-induced arthritis in rats. Materials and Methods: Female Louvain rats were used for this experiment. Rats were randomly assigned into either normal (n=8) or collagen-immunized groups, and collagen immunized groups were divided into control(n=8, normal diet) and n-3 PUFA(n=8, 5% n-3 PUFA in diet) groups. One week after feeding n-3 PUFA to rats, they were immunized with type II collagen emulsified in incomplete Freund's adjuvant into tail and back. Development of arthritis was confirmed by x-ray and microscopic examination. Results: Incidence of arthritis at the 5th week after immunization was 38% in control and 0% in n-3 PUFA. Rats with arthritis showed edema in hind paws and inflammation in synovial membrane of the knee joint. Plasma glucose and insulin were not changed by both of immunization and diet. Plasma triglycerides and cholesterol concentrations were decreased by n-3 PUFA. Conclusion: n-3 PUFA may prevent or treat collagen-induced arthritis m rats. Further studies are needed for action mechanism of it.
