Sjogren's syndrome is an autoimmune disease characterized by dry mouth and neutropenia. Although it does not commonly involve the central nervous system, Sjogren's syndrome sometimes affects small vessels through microangiopathic alterations. A 34-year-old woman was hospitalized for left upper quadrantanopia and a tingling sensation in the left hemibody. Brain magnetic resonance imaging revealed acute infarction in the right posterior cerebral artery territory. In laboratory tests, antinuclear (FANA2+) and anti-DNA antibodies (anti-SS-A (Ro)) were detected. Salivary gland scintigraphy revealed moderately decreasedexcretion of saliva. Based on these findings, we concluded she had Sjogren's syndrome. As in this patient, large vessel involvement in Sjogren's syndrome is far less common. Furthermore, it is difficult to administer antiplatelet drugsto patients with thrombocytopenia in Sjogren's syndrome. This is a case of the patient with Sjogren's syndrome that involved thrombocytopenia and large vessel invasion who was treated with antiplatelet drugs and hydroxychloroquine.

최근에 고령화 사회에 접어들면서 건강하게 활동하며 수명을 다하는 것이 중요한 연구과제가 되고 있다. 이 때문에 영양, 운동, 스트레스, 환경 등과 관련하여 암, 당뇨병, 고혈압, 비만, 동맥경화 등 생활습관병의 극복이 사회문제가 되고 있는 실정이다. 지금까지 고려인삼의 대표적인 동물실험 및 임상학적 연구결과를 종합하여 보면 성인의 난치성 만성질환에 대해서 치료제보다는 질병을 예방하고 회복촉진에 보다 큰 효과 있음을 확인할 수 있다. 이는 인삼이 식품과 의약품의 중간에 위치한 식품의약품(Nutraceutical)의 용도로 활용할 수 있음을 시사한다. 현재까지 인삼제품에 표시되는 기능성의 내용은 약 3,000여편 이상의 약리효능에 관련된 논문이 발표되었다 하더라도 "피로회복, 면역력 증진, 혈소판 응집 억제를 통한 혈액흐름에 도움이 됩니다"이며 이외의 기능성 표시는 현재로서 원칙적으로 불가한 것으로 되어 있다. 그러나 시험물질의 규격화 및 임상시험의 검토기준을 만족시키는 과학적 자료제출에 의한 개별 평가 후 표시내용의 확대가 가능하다. 고려인삼의 다양한 성분 중 ginsenoside는 주요 약효성분으로 인정을 받고 있으며 현재 품질관리의 지표성분으로 활용되고 있다. 이러한 개별 ginsenoside의 약리작용을 보면 서로 유사 또는 상반된 효과를 보여주는 성분들이 공존하고 있어 인삼의 다양한 약리효과와 일맥상통하는 것으로 보고되고 있다. 아울러, ginsenoside는 인삼의 부위 별로 현격한 차이를 보여주기 때문에 소재의 규격화는 매우 중요하다고 판단된다. 따라서, 인삼제품 개발의 가장 중요한 조건은 의약품에 가까운 기능성식품으로 세계적인 제품을 만들기 위해서는 표준화가 선행되어야 한다. 이와 같은 조건을 잘 충족시키는 제품이 스위스 "파마톤의 진사나(백삼추출물, G115)" 제품으로 생각할 수 있다. 따라서, 고려인삼의 수출시장 확대 및 세계적인 제품을 위해서는 진사나에 필적할 수 있는 새로운 홍삼의 표준화된 추출물을 도출하는 것이 무엇보다 급선무라 생각한다. 아울러 고려인삼의 특장점 발굴을 위한 표준화 된 추출분획물, 활성성분 및 효능과 연계한 새로운 고부가가치 창출제품(식품/의약품)개발에 주력해야 할 것이다.

Purpose: The purpose of this study was to construct and test a hypothetical model of self-management in patients with hemodialysis based on the Self-Regulation Model and resource-coping perspective. Methods: Data were collected from 215 adults receiving hemodialysis in 17 local clinics and one tertiary hospital in 2016. The Hemodialysis Self-management Instrument, the Revised Illness Perception Questionnaire, Herth Hope Index and Multidimensional Scale of Perceived Social Support were used. The exogenous variable was social context; the endogenous variables were cognitive illness representation, hope, self-management behavior, and illness outcome. For data analysis, descriptive statistics, Pearson correlation analysis, factor analysis, and structural equation modeling were performed. Results: The hypothetical model with six paths showed a good fitness to the empirical data: GFI=.96, AGFI=.90, CFI=.95, RMSEA=.08, SRMR=.04. The factors that had an influence on self-management behavior were social context (${\beta}=.84$), hope and cognitive illness representation (${\beta}=.37$ and ${\beta}=.27$) explaining 92.4% of the variance. Self-management behavior mediated the relationship between psychosocial coping resources and illness outcome. Conclusion: This research specifies a more complete spectrum of the self-management process. It is important to recognize the array of clinical resources available to support patients' self-management. Healthcare providers can facilitate self-management through collaborative care and understanding the ideas and emotions that each patient has about the illness, and ultimately improve the health outcomes. This framework can be used to guide self-management intervention development and assure effective clinical assessment.

Most cases of eosinophilic pneumonia reported previously have followed a chronic course. The case presented here was acute in onset, suggesting a acute eosinophilic pneumonia. A model of criteria for acute and chronic eosinophilic pneumonia was made by Umeki in 1992. A previously healthy young man presented with cough, sputum, fever, and multiple small nodules on the chest radiograph. We confirmed eosinophilic pneumonia with bronchoalveolar lavage analysis and transbronchial lung biopsy. This case examplifies the recently descrived acute eosinophilic pneumonia.

Inhibition of xanthine oxidase by seaweed extracts obtained from Undaria pinnatifida, Ecklonia stolonifera, Ecklonia cava, Laminaria japonica, Sargassum, Codiumfragile, Enteromorpha compressa and Porphyra tenera were investigated. Extracts of E. stolonifera and E. mua remarkably inhibited xanthine oxidase activity compared to those of other seaweed. The xanthine oxidase inhibitory activity of E. cava was higher than that of E. stolonifera. Diethyl ether extract from E. cava was more effective in the inhibition of xanthine oxidase than other solvent extracts. Two xanthine oxidase inhibitors(A-1 and A-2) from diethyl ether extract were isolated and purified by silica gel column chromatography, thin layer chromatography and high performance liquid chromatography. Xanthine oxidase inhibitory activities of these compounds were 27.8 and 48.1% per 0.4mg, respectively. The active compound A-2 had absorption peak at 420nm, 456nm and 467nm, which can be considered as siphonaxanthine.

연구 목적 : 구취의 주된 화학적 요소는 휘발성 황 화합물 (VSCs)들이다. 이들은 치태, 설태, 타액과 혈액, 상피세포의 혐기성 그람 음성 세균에 의한 단백분해 변성으로 만들어 진다. 또한 구취는 치주질환과 타액내의 세균의 증가를 야기하는 불량한 구강 위생상태에서 기인한다고 보고되고 있다. 이 연구의 목적은 VSCs를 측정함으로 구취에 대한 비외과적 치주 치료의 영향을 평가하고, 타액내의 세균 수를 측정함으로써 VSCs와의 상관관계를 살펴보고자 하는 것이다. 연구 대상 및 방법 : 중등도의 만성치주염을 가지는 23명의 참가자들이 대조군과 실험군으로 분류되었다. 대조군은 구강위생교육 (치간청결기구와 혀세정 포함)만을 시행하였고 실험군은 구강위생교육과 함께 24시간 내에 전악 치석제거술과 치근활택술을 시행하였다. 치료 전과 치료 4주 후에 VSCs 농도를 $Halimeter^{(R)}$(Interscan Corp., CA, USA)를 사용하여 측정하였고 타액 시료는 혐기성과 호기성 조건에서 배양되었다. 결과 : 4주 후에 두 군 모두에서 휘발성 황화합물의 농도가 유의하게 감소하였고, 실험군에서의 감소량이 통계적으로 유의하게 더 크게 나타났다. 타액 내 세균의 배양에서 총세균수에 대한 혐기성 세균의 비율이 실험군에서만 통계적으로 유의하게 감소하였다. 그러나 세균의 비율과 휘발성 황화합물의 농도와의 상관관계는 낮게 나타났다. 즉 구취의 감소는 타액 요인 보다는 치주치료에 의한 다른 복합적인 인자의 작용에 의한 것으로 추론할 수 있었다. 결론 : 본 연구는 중등도의 치주염환자에서 구강위생교육만으로도 구취의 주요 화학적 요인인 휘발성 황화합물의 농도를 감소시킬 수 있으나 비외과적 치주치료를 동반하였을 때 더욱 큰 효과를 얻을 수 있는 것으로 해석된다. 그러나 실험 참가자의 수가 적었고 장기간의 분석이 이루어지지 않았으므로 앞으로 더 많은 연구가 구취에 대한 치주치료의 영향을 이해하기 위해서 필요할 것으로 사료된다.

Posttranplantations lymphoproliferative disease (PTLD) is a common and life-threatening complication for soid organ transplantation associated with the use of chronic immunosuppression and Epstein-Barr virus. There is no standardized treatment algorithm, but numerous management strategies are vaiable. Partial splenic embolization (PSE) had been demonstrated to be an effetive alternatie to splenectomy for patients hypersplenism and portal hypertension. PSE has the advantages of non-invasive intervention and resolution of the complications of hypersplenism. We report the effect of the PSE in a 6-year old male liver transplantation recepient with PTLD who has undergone persistent hypersplenism post-transplant. We reduced immunosuppression agent, started antiviral agent. We started with interferon and IV globulin one month after admission. Hepatosplenomegaly and cervical lymphadenopathy were improved. But fever was not subside. We selectively embolized the lower pole of the spleen to achieve a 50~60% reduction in flow as determined by angiography. After embolization, fever subside and peripheral blood findings were improved. Follow up abdominal CT revealed reduced volume of spleen due to ischemic change and there was no multiple enlarged mesenteric lymphnode compared to preembolization state. We thick that PSE is a safe an effetive treatment modality of PTLD with persistent hypersplenism in patients twho failed to medical treatment.

Cystinosis, an autosomal recessively inherited lysosomal storage disease, results from impaired transport of the amino acid cystine out of cellular lysosomes. The consequent accumulation and crystallization of cystine destroys tissues, causing growth retardation, Fanconi syndrome, renal failure, eye problems, and endocrinopathies. The gene for cystinosis, CTNS, was mapped to chromosome 17p13. The diagnosis of cystinosis is made by measuring the leukocyte cystine content and the presence of typical corneal crystals on slit-lamp examination is also diagnostic. Since treatment with cysteamine has proved extremely effective, early diagnosis and treatment are critical aspects. We experienced a typical case of cystinosis in a 12-year-old boy with growth retardation.

Objectives : To investigate the clinical features of drug-induced liver injury (DILI) and traditional Korean medicine (TKM) -based management. Methods : A female patient diagnosed with DILI caused by Western drugs had been treated with Oriental therapies, then the subjective clinical outcome and biochemical parameters were monitored. Results : A 73-year-old female had taken Western drugs (nonsteroidal anti-inflammatory and skeletal muscle relaxants) for about 3 months, and complained of severe abdominal discomfort and tiredness. Her RUCAM score was 9, which met the criteria for DILI (AST 90 IU/L, ALT 100 IU/L, ALP 191 IU/L, and GGT 614 IU/L). She was treated with herbal drugs, moxibustion, and acupuncture, and her symptoms completely resolved, with normalized hepatic enzymes within two weeks. Conclusions : This case report provides a clinical characteristic for a typical DILI caused by Western medicine, and shows an example of a TKM-based application.

With the improvement of hemodialysis, the course of the disease in patient with endstage renal disease has been clearly improved. Nevertheless, among several shortcomings to our present mode of renal replacement therapy, cardiovascular complications have been the leading cause of morbidity and mortality. Several factors such as anemia, arteriovenous shunting of blood, intermittent extracorporeal circulation and hypertension may be contributing. But little is known about the quantitative cardiac hemodynamic characteristics occurred during hemodialysis. The purpose of this study is to observe the sequential hemodynamic changes before, during and after the hemodialysis and to investigate reliable parameters in the detection of ventricular dysfunction. In the present study, equilibrium radionuclide cardiac angiography was performed and left and right ventricular volume indices, ejection phase indices of both ventricular, performance were measured in the 16 stable patients with chronic renal failure treated with maintenance hemodialysis sequentially i.e. before, during (early and late phase) and after the hemodialysis. The results obtained were as follows; 1) The indices of the left ventricular function were not changed during the hemodialysis but increased after the hemodialysis. 2) The indices of the right ventricular function(EF, SVI) were significantly decreased in the early phase (15, 30 minutes after starting extracorporeal circulation) but recovered after the hemodialysis. 3) The ratio of right ventricular to left ventricular ejection fraction was significantly decreased in the early phase and the lung volume indices were significantly increased at the same phase. As a conclusion, hemodialysis improves left ventricular function maybe due to increased contractility, and effects on the right ventricular function maybe due to the increased lung volume in the early phase of hemodialysis.
