  • 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.

  • 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.

  • Objectives : This study was carried out to understand the immunity responses and anti-oxidation effect of the Gamidaeganghwal-tang(GDT) on rheumatoid arthritis by using the THP-1 cells and the serum of CIA mice. Methods : For this purpose, GDT was orally administerd to mice with rheumatoid arthritis induced by collagen II. To investigate the immunity responses, value of cytokine and gene expression in the THP-1 cell, levels of cytokines in the serum of CIA(collagen type II induced arthritis) mice, number of immunocyte in PBMC of CIA mice were measured. Then, anti-oxidant activity, scavenging activity on DHHP(2,2-diphenyl-1-picrylhydrazyl) free radical and SOD(Superoxide dismutae)-like activity of GDT was observed. Results : 1. The levels of IL-$1{\beta}$, IL-6, IL-8, MCP-1 at 100, $50{\mu}g/m{\ell}$ of GDT were significantly reduced in the THP-1 cell. 2. The levels of TNF-${\alpha}$, COX-2 mRNA expression at 100, $50{\mu}g/m{\ell}$ of GDT and IL-$1{\beta}$, IL-6 at $100{\mu}g/m{\ell}$ of GDT were significantly reduced in the THP-1 cell line. 3. The levels of IL-6, TNF-${\alpha}$ and IL-$1{\beta}$ were significantly reduced in the serum of CIA mice. 4. The absolute number of CD3+, CD4+ and CD8+ cells were significantly induced, CD3+/CD69+, CD3+/CD49+, CD19+, B220+/CD23+ cells were significantly reduced in PBMC. 5. Scavenging activity on DPPH free radical and SOD-like activity were significantly induced in a concentration dependent manner. Conclusions : Taking all these observations, GDT considered to be effective in treating rheumatoid arthritis. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • Purpose: The purpose of this study was to examine the effects of a self-management program on self-efficacy and quality of life for Korean women with rheumatoid arthritis. Methods: A quasi-experimental study using a nonequivalent control group pretest posttest design was used. The data were collected from July 1 to Sep. 15, 2007. Thirty one arthritis patients (15 in the experimental group and 16 in the control group) were participated in this study. A self-management program developed by Korean Society of Muscle and Joint Health in 1994 was used. The program was consisted of 6 sessions, 2 hours each and held every Friday for 6 weeks. General Self-Efficacy Scale and Quality of Life were used to test the effect of the program. Results: Hypothesis 1; "Self-efficacy in the experimental group after program would be higher than the control group" was supported. Hypothesis 2; "Quality of Life in the experimental group after program would be higher than the control group " was not supported. Conclusion: The self-management program was effective for Korean women with rheumatoid arthritis in terms of increasing self-efficacy. Therefore, to increase self-management skills and self-efficacy for female rheumatoid arthritis patients, the program can be useful.

  • To purpose of this study was to evaluate clinical results between rheumatoid arthritis shoulder cases and traumatic proximal humerus fracture cases. Fourteen patients who had been shoulder hemiarthroplasties between March 1991 to July 1996, six had rheumatoid arthritis and eight had comminuted proximal humerus fracture by the various trauma. Neer II prothesis were implanted in twenty cases and global prothesis were implanted in two cases. The follow up period was 15 months to 36 months. To evaluate this study, we used the UCLA shoulder rating. We were able to follow up thirteen cases for more than fifteen months, of which five cases had excellent, five cases had good, two cases had fair and one case had poor. And the results were better for patients with rheumaroid arthritis than for patients with trauma.

  • Rheumatoid arthritis is an incurable chronic inflammatory and destructive arthopathy that affects 1% of the population world-wide. It has substantial personal, social and economic costs. The long-term prognosis is poor: 80 percent of affected patients will become disabled within 20 years after onset of disease. Medical costs of rheumatoid arthritis average ∼$ 6000 (US) per patient (1), Current antirheumatic drugs have limited efficacy and many side effects and more importantly they do not improve the long-term prognosis of rheumatoid arthritis (2). After a decade of few notable advances in therapy, several biological response modifiers that target pathophysiological processes in the disease have now emerged in the clinic. These new drugs are termed biological agents, and although information about their use in the clinic is still limited to short term treatment, they appear to have the ability to modify disease progress. In addition, COX-2 selective agents have now been approved that have comparable efficacy with standard NSAIDs, but fewer gastrointestinal side effects (3). Thus today many more therapeutic options are suddenly open to patients that even five years ago had little hope of relief from chronic pain and inflammation.

  • Dendritic cells (DCs) are professional antigen presenting cells, and play an important role in the induction of antigen-specific adaptive immunity. However, some DC populations are involved in immune regulation and immune tolerance. These DC populations are believed to take part in the control of immune exaggeration and immune disorder, and maintain immune homeostasis in the body. Tolerogenic DCs (tolDCs) can be generated in vitro by genetic or pharmacological modification or by controlling the maturation stages of cytokine-derived DCs. These tolDCs have been investigated for the treatment of rheumatoid arthritis (RA) in experimental animal models. In the last decade, several in vitro and in vivo approaches have been translated into clinical trials. As of 2015, three tolDC trials for RA are on the list of ClinicalTrial.gov (www.clinicaltrials.gov). Other trials for RA are in progress and will be listed soon. In this review, we discuss the evolution of tolDC-based immunotherapy for RA and its limitations and future prospects.
