Background: The aim of this study was to investigate the mid-term outcomes of our modifications to the maze procedure using cryoablation for treating atrial fibrillation associated with rheumatic mitral valve disease. Material and Method: Between March 2000 and February 2004, 177 consecutive patients underwent the modified maze procedure with the use of cryoablation concomitant with mitral valve surgery for atrial fibrillation associated with rheumatic mitral valve disease, and were divided into three groups: (1) modified Cox-maze III (CM group, n=88): (2) modified Kosakai-maze (KM group, n=63): and (3) left atrial maze procedure (LA group, n=26). The postoperative and follow-up results were analyzed and compared between the groups. Result: There were three hospital deaths (1.7%) and no significant differences in the incidence of postoperative complications between the three groups. The operative time, such as the cardiopulmonary bypass and aortic crossclamp time, were significantly longer in the CM group than in the KM and LA groups, respectively (p<0.0001). The mean follow-up was $22.4{\pm}15.1$ months ($1\sim52.6$ months) for all patients. One late death developed in the CM group (0.0%). At last follow-up, 139 patients exhibited sinus rhythm (79.9%), which was also regained in 67 patients (77.9%) in the CM group, 50 (80.7%) in the KM group and 22 (84.6%) in the LA group (p=0.743). The actuarial freedom from stroke at 4 years was $84.5{\pm}9.4%$ in the CM group, $95.0{\pm}4.9%$ in the KM group, and $92.9{\pm}6.9%$ in the LA group (p=0.916). Conclusion: The modified maze procedure using cryoablation is safe and effective in treating chronic atrial fibrillation associated with rheumatic mitral valve disease.

실험목적 : 빈소산은 11가지 생약으로 구성된 복합 한약 처방으로 관절염을 포함한 다양한 염증성 질환의 치료제로 사용되어 왔으나, 관절염에 대한 직접적인 효력평가는 찾아 보기 힘들다. 따라서 본 실험에서는 빈소산 추출물이 Freund's complete adjuvant (FCA)로 유발된 rat 류마티스성 관절염에 미치는 치료 효과를 dexamethasone (15mg/kg, 복강 투여) 의 효과와 비교 평가하였다. 실험방법 : 류마티스성 관절염은 FCA (10mg in 1ml paraffin oil 0.1ml/rats)를 좌측 후지에 피내 투여하여 유발하였다. 실험동물은 Wistar 랫트를 사용하였고, FCA 투여 14일 후 유사한 무릎관절 둘레를 나타내는 류마티스성 관절염 유발 rat와 정상 rat 및 실험군을 그룹당 9마리씩 나누었다. 실험동물은 100 또는 200mg/kg의 빈소산 추출물을 FCA 투여 14일 후부터 14일간 경구 투여하였으며, dexamethasone은 15mg/kg 농도로 복강 투여한 다음, 희생하여, 체중, 연골내 collagen 함량 및 chondroitin sulphate, heparin sulphate 및 hyaluronic acid와 같은 뼈내 glycosaminoglycan 함량의 변화를 각각 관찰하였다. 실험결과는 항염 효과가 이미 입증되어 있는 dexamethasone 15mg/kg 복강 투여군과 비교하였다. 결과 : FCA 투여는 현저한 체중, 연골내 collagen 함량 및 chondroitin sulphate, heparin sulphate 및 hyaluronic acid와 같은 뼈내 glycosaminoglycan 함량의 감소와 함께 유발 관절 둘레 및 조직내 prostaglandin $E_2$의 증가와 같은 전형적인 류마티스성 염증을 초래하였으나, 이러한 류마티스성 관절염 소견은 dexamethasone 및 모든 용량의 빈소산 추출물 투여에 의해 현저히 억제되었으며, 특히 빈소산 투여군에서는 투여 용량 의존적인 감소가 인정되었다. 결론 : 이상에서 빈소산 추출물은 투여 용량 의존적인 prostaglandin $E_2$ 억제를 매개하여 FCA 유발 류마티스성 관절염에 대한 치료 효과를 나타내는 것으로 관찰되었다. 따라서 새로운 관절염에 대한 치료제로서 개발 가능성이 있을 것으로 판단된다. 한편 빈소산 추출물은 주로 prostaglandin $E_2$ 억제작용에 의해 항염 효과를 나타내는 것으로 관찰되었으나, 금후 다른 작용기전에 대한 연구와 빈소산의 구성성분 중 유효 성분 규명을 위한 실험이 수행되어야 할 것으로 판단된다.

Juvenile rheumatoid arthritis(JRA) is the most common major connective tissue disease in children. Renal involvement in JRA is rare. Among the renal lesions that have been reported in JRA, amyloidosis and drug-induced nephropathy are the most common. Crescentic glomerulonephritis in JRA has rarely been reported. We report a case of ANCA-associated pauci-immune crescentic glomerulonephritis in JRA. The patient was a 15-year old boy with a 3-year history of JRA. He presented with gross hematuria, proteinuria, positive p-ANCA and elevation of BUN and creatinine. Pathologic findings revealed focal necrotizing and crescentic glomerulonephritis. There were no significant immunoglobulin or complement deposits. His renal function recovered after intravenous methylprednisolone pulse therapy and oral steroid use. In Korea, this is the first reported case of pauci-immune crescentic glomerulonephritis in JRA. (J Korean Soc Pediatr Nephrol 2005;9:231-236)

Chronic inflammation is involved in cancers, rheumatoid arthritis, and Crohn's disease. Inerleukin-6 (IL-6) plays major roles in inflammation. Chungkookjang, fermented soybean contains diverse peptides produced by cleavage of soybean proteins. The peptides can be bioactive compounds. Peptide (Gly-Val-Tyr-Tyr-Met-Tyr was purified from Chungkookjang, and modified to be 6mer H, Glu-Val-Tyr-Tyr-Met-Tyr (EVYYMY). Peptide H's activity to suppress IL-6 expression in a human breast cancer cell, MDA-MB-231 was determined. IL-6 Expression was reduced in the cell treated with peptide H 25 times less than controls which were not treated with peptide H. Proliferation of MDA-MB-231 cells was inhibited by peptide H, which is concentration-dependent. Blocking of IL-6 signals is known to be effective in reducing inflammation in rheumatoid arthritis, Crohn's disease, and cancers. Since peptide H can reduce inflammatory IL-6 expression, application of this study will contribute to drug development for diseases which are caused by excessive IL-6.

This study was designed to explore use of unconventional treatments and identify related variables of patients with rheumatic disease. One hundred fifty rheumatic patients were recruited from two university based rheumatic centers according to selection criteria. Collected data were analyzed using SAS program through with a structured questionnaire. T-test, ANOVA, and Scheffe's test were adopted. The results were as follows: 1. 77.7% of the subjects were over forties and mean age was 48.5 years. 74.0% were women and 73.2% were living with their spouse. 82.0% of them was good or moderate or good economic status, 38.3% was university graduates. 2. 58.0% of the subjects had rheumatoid arthritis, and mean duration of suffering rheumatic disease was 6.5 years. 89.3% of them had joint pain and their mean pain score was 4.07. Most painful joints were hip(58.0%), finger(42.0%), wrist(42.0%), and the number of painful joint was 5.4. 70% of the subjects using unconventional treatments, the most common treatments using them was herb medicine(42.7%) and acupuncture(36.7%). 3. Level of pain was different according to subject's age, educational background, diagnosis, number of painful joints, and using unconventional treatments or not. It is recommended that use of a larger sample to understand more about unconventional treatments and pain of patients with rheumatic disease. More research is needed to consider developing individual nursing interventions for their well-being and quality of life.

Mixed connective tissue disease (MCTD) is characterized by diverse symptoms including rheumatoid arthritis, scleroderma, systemic lupus erythematosus, and dermatomyositis, associated with high titers of antibodies to extractable nuclear antigen (ENA), especially anti-ribonucleoprotein (anti-RNP) antibody. Since the first report of 25 cases with MCTD in adults, there have been only a few cases of MCTD reported in children. Here, we report a rare childhood case of MCTD in a 7-year-old girl presenting initially with Raynaud's phenomenon, swollen hands, and ulceration of the right index finger tip followed by alopecia and arthritis during follow-up.

Sulfasalazine is a disease-modifying antirheumatic abiotic agent. It is a derivative of aminosalicylic acid and has been used for the treatment of various inflammatory diseases, such as rheumatoid arthritis, ulcerative colitis, and Crohn's disease, since it was first synthesized in 1941 and approved as a medicine in the United States in 1950. However, its mechanism of action has not yet been clearly identified. In this study, the effects of sulfasalazine on cell survival, apoptosis, and cell cycle progression in macrophages, which are major immune cells that regulate inflammatory responses, were investigated using mouse macrophage RAW 264.7 cells. Sulfasalazine inhibited the viability of RAW 264.7 cells in a dose-dependent manner, starting at a concentration of 0.25 mM. Annexin-V staining was used to confirm that the decrease in cell viability was due to apoptosis, and the number of Annexin-V-positive cells increased significantly at a concentration of 0.25 mM or higher. The effect of sulfasalazine on the expression of key proteins that regulate the G0/G1 phase of the cell cycle was also investigated. Sulfasalazine treatment significantly increased the expression of the cyclin-dependent kinase inhibitors p21 and p27 in RAW 264.7 cells. Although sulfasalazine is frequently used as a control drug in studies on inflammatory diseases, such as inflammatory colitis and rheumatoid arthritis, studies on its effect on macrophages are very limited. Therefore, the results of this study are expected to provide vital information on the use of sulfasalazine as a disease treatment.

The incidence of degenerative valve disease also increasing with the increasing life expectancy of the elderly population. Rheumatic valve disease is decreasing gradually and the incidence of calcified degenerative aortic stenosis (AS) is growing. Echocardiography is a very important tool for evaluating the prognosis and treatment method as well as the time of operation and diagnosis of heart valve disease. When evaluating valvular heart disease, 2-dimensional echocardiography, which observes all heart valves in detail, should take precedence. Understanding the clinical findings of degenerative valve disease and performing precise echocardiography are extremely important. In addition, an assessment of the severity of aortic stenosis is necessary to determine the surgical indications. An assessment of the severity by echocardiography was explained with three cases of degenerative aortic stenosis. To perform echocardiography accurately, it is necessary to understand degenerative valve disease and its clinical findings accurately.
