  • For evaluating the effect of Siegesbeckiae Herba (here after abbreviated as SBH) on rheumatoid arthritis, the experiment was carried out; Incidence of rheumatoid arthritis, IRA(indices of rheumatoid arthritis), immunophenotypes by flow cytometer and histopathological changes in MRL/MpJ-Ipr-Ipr Mice in vivo were studied. The results were obtained as follows: 1. Incidence of RA in MRL/Ipr mice was suppressed to 60% of control by SBH. 2. IRA was significantly reduced for IgG3 and IgM at 20 weeks of age and for IgG2b at 12 and 20 weeks of age in mice by SBH compared with control. 3. Immunophenotypes such as CD4/sup +//CD25/sup +/, CD8/sup +//CD3e/sup +/, CD69/sup +//B220/sup +/, NK/sup +//CD3e/sup +/ were significantly increased by SBH compared with control. 4. In histopathological analysis, SBH suppressed the progression of PMN(polymorphonuciear leukocyte), leukocyte and fibroblast infiltration, and subsynovial soft tissue edema frequently showing in the early stage of the arthritis, and also effectively reduced the degeneration of cartilages and degenerative bone symptoms. These results suggest Siegesbeckiae Herba can be effectively applied to the treatment of rheumatoid arthritis and it is still necessary to isolate effective compound from Siegesbeckiae Herba in the near future.

  • 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.

  • Objectives : The aim of this study was to know the immunity reponse of Esubwhaltong-tang(hereafter referred to ESWTT) to rheumatoid arthrits in CIA(collagen induced arthritis) mice. Methods : For this purpose, ESWTT was orally administerd to mice with arthritis induced by collagen II and then value of immunocyte in paw joint, cytokine(IL-6, $TNF-{\alpha}$), rheumatoid factor(IgG and IgM) and collagen II specific antibody in the serum were measured. Results : 1. The cytotoxicity was not shown on hFLSs and liver. 2. Marginal erosion, necrotic chodrocytes, cartilage and bone degradation were improved in histological section of paw joints from CIA mice(ESWTT extract administration group). 3. Total cell number of paw joint in CIA mice(ESWTT extract administration group) was decreased significantly. 4. The absolute number of CD3+, CD3+/CD69+, CD4+, CD4+/CD25+, CD49b+, CD3+/CD49b+ cells in CIA mice(ESWTT extract administration group) were decreased significantly. 5. The levels of IL-6 and $TNF-{\alpha}$ in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 6. The levels of total IgG and IgM in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 7. The level of collagen II specific antibody in the serum of CIA mice(ESWTT extract administration group) was decreased significantly. Conclusions : Comparison of the results for this study showed that ESWTT had immunomodulatory effects of suppressing. So we expect that ESWTT could be used as an effective drugs for not only rheumatoid arthritis but also auto-immune disease.

  • Objectives : Smilacis glabrae rhizoma (SG) has been traditionally used as a herbal medication of musculoskeletal disorders like arthritis, pain, convulsions, and syphilis in traditional Korean medicine. This study was investigated anti-oxidative and anti-inflammatory effect of fractionated extracts of Smilacis Glabrae Rhizoma in Human Umbilical Vein Endothelial Cell (HUVEC). Methods : SG extract prepared with methanol, and then fractionated with hexane, dichloromethane, ethylacetate, n-butanol and water. Inhibitory effect of SG onto free radical generation was determined by measuring DPPH, superoxide anions and nitric oxide scavenging activities in vitro. Cytotoxic activity of extracts on RAW 264.7 cells was measured using 5-(3-caroboxymethoxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. Intracelluar oxidation was analysed by DCF-DA assay. The nitric oxide (NO) production was measured by Griess reagent system. The levels of ICAM-1 and VCAM-1 expression were confirmed by western blot. And proinflammatory cytokines were measured by ELISA kit. Results : Our results indicated that fractionated extracts, especially ethyl acetate (EA) extract, significantly inhibited free radical generation, the TNF-$\alpha$-induced intracellular oxidation. Furthermore, the EA extract protected TNF-$\alpha$-induced adhesion to THP-1, expression of adhesion molecules accompanied by an attenuation of IL-6 and IL-8 formation in HUVEC. Conclusions : These results indicate that EA extract of SG have potential as an agent of atherosclerosis and other chronic inflammatory diseases including diabetes, hypertension, and arthritis.
