  • 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.

  • Collagen-induced arthritis (CIA) is a model for some types of human autoimmune rheumatoid arthritis (RA). In this study, we examined whether ethanol extract of potato (Solanum tuberosum) is efficacious against CIA in mice. Potato extracts (100 and 200 mg/kg) were orally administered to DBA/1J mice once daily for 49 day after initial immunization with type II collagen. Clinical assessment of disease and measurement of paw edema were conducted throughout the study. The production of CIA-related rheumatoid factor, anti-type II collagen antibody, and cytokines were examined in DBA/1J mice. Serum levels of AST, ALT, creatinine, and lipids were measured, and antioxidant enzyme activity in the spleen was also determined. The arthritis score and paw edema were markedly suppressed in the groups treated with potato extract. Levels of rheumatoid factor, anti-type II collagen antibody, interleukin (IL)-1, IL-6, LDL-cholesterol, and malondialdehyde in sera were also reduced by potato extract treatment. The activities of glutathione peroxidase and glutathione reductase were increased in the spleens of CIA mice treated with potato extract. These findings suggest that potato extract has suppressive effects on type II collagen-induced arthritis, an animal model for human RA.

  • This study examined the effects of calcium (Ca) gluconate on collagen-induced DBA mouse rheumatoid arthritis (CIA). A single daily dose of 200, 100 or 50 mg/kg Ca gluconate was administered orally to male DBA/1J mice for 40 days after initial collagen immunization. To ascertain the effects administering the collagen booster, CIA-related features (including body weight, poly-arthritis, knee and paw thickness, and paw weight increase) were measured from histopathological changes in the spleen, left popliteal lymph node, third digit and the knee joint regions. CIA-related bone and cartilage damage improved significantly in the Ca gluconate-administered CIA mice. Additionally, myeloperoxidase (MPO) levels in the paw were reduced in Ca gluconate-treated CIA mice compared to CIA control groups. The level of malondialdehyde (MDA), an indicator of oxidative stress, decreased in a dose-dependent manner in the Ca gluconate group. Finally, the production of IL-6 and TNF-${\alpha}$, involved in rheumatoid arthritis pathogenesis, were suppressed by treatment with Ca gluconate. Taken together, these results suggest that Ca gluconate is a promising candidate anti-rheumatoid arthritis agent, exerting anti-inflammatory, anti-oxidative and immunomodulatory effects in CIA mice.

  • The influence of moxibustion, a traditional Chinese medical treatment, on type II collagen-induced arthritis (CIA) was examined in DBA/1J mice in vivo. Mice were immunized intradermally twice at the 3-week interval with bovine type II collagen (C Il). The main incidence of arthritis started about on day 30 and lasted to day 60 after the first immunization. Moxibustion with three different regimens, was applied at the acupoint equivalent to GV 4 every other day. Moxibustion, from day 0 to day 30 after the first immunization, suppressed the onset and development of arthritis, as well as anti-collagen antibody level. Treatment with moxibustion, from the day 31 to day 60, also resulted in a significant inhibition of progression of arthritis and production of anti-C II antibody. Thirdly we examined the influence of moxibustion on the established arthritis. Moxibustion given from day 61 to day 120, significantly but mildly decreased the anti-C II antibody level in diseased mice, while the bone erosion and joint destruction were not affected. These results indicate that moxibustion could prevent the incidence and attenuates the development of murine CIA.

  • Objectives & Methods : The purpose of this study is to observe the effects of Coicis Semen Herbal-acupuncture solution (CS-HAS) at the Joksamni (ST36) on the collagen-induced arthritis in the DBA/1J mouse. The author performed several experiments to analyze the effects of CS-HAS on arthritis; change of the weight; the spleen size and adhesion rate; serum cytokine levels; serum antibody levels; changes of immunocyte counts; the histological changes of joint. Results : In the Coicis Semen Herbal-acupuncture (CS-HA), arthritis index, the incidence of arthritis, and the degree of joint edema were decreased. In CS-HA, there was no weight loss. The size of the spleen, adhesion rate, and the edema and transformation of joint were lowered. In CS-HA, the levels of IL-1${\beta}$, IL-6, TNF-${\alpha}$, IFN-${\gamma}$, IgG, IgM, and anti-collagen II in serum and the levels of IFN-${\gamma}$, IL-4, IL-10 in spleen were significantly decreased. In CS-HA, the expression ratios of $CD45^+$ to $CD3e^+$ and $CD8^+$ to $CD4^+$ were decreased. Also, the overall $CD4^+/CD8^+$ cell ratio was lowered in spleen. Ratios of the $CD4^+/CD25^+$, $CD45^+/CD69^+$ cells were decreased in lymph nodes. In addition, ratios of the $CD3^+/CD69^+$, $CD11b^+/Gr-1^+$ cells were also decreased in synovium. In the histological study, the cartilage destruction and synovial cell proliferation, and collagen fiber destruction were decreased with CS-HA treated group. Conclusions : From the results mentioned above, it is suggested that CS-HA at the ST36 has several significant effects on the collagen-induced arthritis.
