  • Corilagin (CRN) isolated from Euphorbia helioscopia as rheumatoid arthritis drug. CRN was medicated to the abdominal cavity of collagen induced arthritis (CIA) mice that was an animal model for rheumatoid arthritis and its effects on incidence and arthritis index were studied. The results were as folllows; It was exhibited that medicating corilagin inhibited the infiltration of activated T lymphocytes into an inflammatory joint. The production of IgG and IgM that were RF (rheumatoid factor) and inflammatory cytokine, IL-6 and $TNF-{\alpha}$were reduced. After measuring $IFN-{\gamma}$and IL-4, it was found that it was shifted into Th2 immune response as increasing in IL-4. After liver function test, studies on liver poisoning of AST/ALT should be continued.

  • Rheumatoid arthritis (RA) is a connective tissue disease involving the larynx in 30 % of the patients. Foreign body sensation, hoarseness, and cough are common symptoms in laryngeal involvement. An urgent tracheostomy is required when acute airway obstruction occurs in case of bilateral vocal fold paralysis. The most common cause of bilateral vocal fold paralysis in RA patients is a cricoarytenoid joint arthritis. Laryngeal nerve degeneration is rare cause of bilateral vocal fold paralysis in RA patients. In this case report, an emergent tracheostomy was performed on a 64-years-old male patient with acute dyspnea, and concurrent involvement of RA on laryngeal nerve and cricoarytenoid joint was revealed by laryngeal electromyography and histopathology. The vocal fold mobility was restored after 3-months medical treatment.

  • The effect of beta-glucan ($Polycan^{TM}$) derived from Aureobasidium pullulans SM-2001 were observed on, collagen-induced rheumatoid arthritis (RA) in DBA mice. Six week-old male DBA/1J mice were immunized by the intradermal injection of $200\;{\mu}g$ of bovine type II collagen with the equal volume of complete Freund's adjuvant at the tail base on day 1. On day 21, the mice were boosted by the intradermal injection of $200\;{\mu}g$ of bovine type II collagen with incomplete Freund's adjuvant. From the first immunization, mice had been administered $Polycan^{TM}$ (21.25, 42.5 and 85 mg/kg), diclofenac and vehicle once a day for 4 weeks, respectively. Collagen-induced hyperimmunities and arthritis signs were markedly and dose-dependently inhibited by treatment of $Polycan^{TM}$ compared with RA control except for tibial cartilages of $Polycan^{TM}$ 21.25 group. $Polycan^{TM}$ effectively inhibited the histopathological changes of collagen-induced arthritis and hyper-immunities.

  • Purpose: We investigated whether Tc-99m MIBI imaging is useful to predict the response of drug treatment in patients with rheumatoid arthritis. Materials and Methods: 24 patients (15 women and 9 men, age $49{\pm}12$ year) rheumatoid arthritis and treated with disease modifying antirheumatic drugs (DMARDs) were included in this study. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured, and Tc-99m MIBI scan was obtained before drug treatment. Quantitative analysis of uptake in diseased joints was performed and expressed as joint-to background ratio (J/B) and percent retention (%R) of Tc-99m MIBI. Clinical symptoms were evaluated and graded from 0 (no) to 3 (severe) regarding to presence of tenderness and swelling. Results: J/B of the diseased joints were significantly correlated with ESR and CRP (p<0.05). A highly significant correlation was found between the improvement of clinical symptoms and %R of Tc-99m MIBI (p<0.05). Conclusion: The results demonstrate that Tc-99m MIBI scan may be used to predict the therapeutic response in patients with rheumatoid arthritis.

  • Rheumatoid nodules are the most common extra-articular presentations of rheumatoid arthritis. Although rheumatoid nodules can develop anywhere in the body, they develop most commonly in the subcutaneous region, where they are easily exposed to repetitive trauma or pressure. However, an infrascapular presentation has not yet been reported. We report a case of giant bilateral rheumatoid nodules that developed in the infrascapular area, complicating its distinction from elastofibroma dorsi on radiological examination.

  • Background: Rheumatoid arthritis is an autoimmune disease characterized by a chronic inflammatory process, primarily involving the synovial membrane of peripheral j oints, where T cell activation is found. To address the superantigen stimulation in rheumatoid arthritis, T cell clonality and the expression of activation markers were analyzed. Methods: To detect TCRB V usage, inverse PCR and sequencing were done. Monoclonal antibodies were used for flow cytometric analysis of TCRBV8 or TCRBV5. As results, a restricted usage of TCRBV3 gene was detected in synovial lymphocytes from one rheumatoid arthritis patient. However, preferential usage for TCRB V8, which may be one indicator for stimulation by staphylococcal superantigen, was not obvious although general activation of T cells was found as high DR+ percentage in synovial T cells. These data show specific antigen rather than superantigen might involve the pathogenesis of rheumatoid arthritis.

  • Purpose: The purpose of the study was to compare the effects of Tai Chi exercise program on arthritic pain, difficulties in performing activities of daily living, and fear of falling in women with osteoarthritis (OA) and rheumatoid arthritis (RA). Method: A quasi-experimental design with two intervention groups was used. According to the inclusion criteria, 35 women with OA and 22 with RA were recruited and participated in the Tai Chi for arthritis program for 12 weeks. In 12 weeks, 21 in the OA group and 15 in the RA group completed both pretest and posttest measures. Outcome variables consisted of pain, difficulties in performing activities of daily living, and fear of falling for both groups. Results: The women with OA (64 years) were significantly older and perceived better health than those with RA (49 years) with more than 6 years of diagnosis. The pain scores and the performance of activities of daily living were significantly improved in the OA group at the completion of 12 week Tai Chi exercise, but RA group decreased pain only. The improvements in pain and activities of daily living were significantly more in women with OA than those with RA. No significant changes were found in fear of falling for both groups. Conclusion: The 12 week Tai Chi exercise was more effective on pain and activities of daily living for women with OA than those with RA. Considering that the women with RA perceived more pain and had limited activities of daily living, Tai Chi exercise should be applied slowly and gradually for longer period of time than those with OA.
