Brugada syndrome is characterized by right bundle branch block morphology and ST segment elevation in the right precordial leads and a propensity to develop ventricular arrhythmias. Mutations in a cardiac sodium channel gene have been linked to this syndrome, and the ionic mechanisms responsible for the electrocardiographic phenotype are temperature-dependent. This case report describes a patient in whom a typical Brugada ECG pattern developed during fever and returned normal ECG after fever was subsided.

Metamifop, (R)-2-[4-[(6-chloro-2-benzoxazolyloxyphenoxy]-N-(2-fluorophenyl)-N-methyl propanamide, was newly developed by Dongbu Hannong Chemicals in Korea. In the present study we conducted acute oral toxicity and acute dermal toxicity test. The values of LD_(50) of metamifop was found to be over 5,000 mg/kg for ICR mice. On the other hand, metamifop showed no acute dermal toxicity to SD rats.

배경 : 2002년 내국인에서의 첫 사람 브루셀라증의 증례 보고 이후 국내에서 사람 브루셀라증이 빠른 증가를 보이고 있다. 이에 연구자들은 국내에서 발생하는 브루셀라증의 임상적 특성을 연구하고자 하였다. 방법 : 2003년부터 2006년 7월까지 7개 대학병원에 내원한 환자들을 대상으로 WHO의 진단기준에 의하여 확진된 브루셀라증 환자들의 의무기록을 후향적으로 조사분석 하였다. 배양된 균은 삼성서울병원에 의뢰하여 16S rRNA 유전자 분석방법을 이용하여 종을 확인하였고, 표준시험관응집검사는 국립보건원에 의뢰하여 시행하였다. 결과 : 34예의 환자들이 브루셀라증으로 확진되었고, 31명이 남자였다. 혈액에서 B. abortus가 증명된 경우가 8예, 표준시험관 응집검사상 의미 있는 항체가 상승을 보인경우가 26예이었다. 환자들은 대부분 축산업관련 종사자였고, 추후 브루셀라증으로 확진된 소와의 직접 접촉을 통해 감염된 것으로 여겨진다. 국내 사람 브루셀라증의 가장 흔한 증상은 발열이었고, 위장관계 합병증이 가장 흔히 동반되었다. 치료로는 doxycycline/rifampicin이 24예의 환자에서 doxycycline/aminoglycoside (streptomycin 혹은 gentamicin)이 10예의 환자에서 6주 이상의 기간 동안 투여되었다. 치료에 반응을 보이지 않는 환자는 없었고, 재발이 1예 있었다. 결론 : 국내에서 발생하는 사람 브루셀라증의 원인균으로 현재까지 분리 동정된 것은 B. abortus이며, 소 브루셀라증의 증가로 인해 인체감염사례가 함께 증가하는 것으로 사료된다. 위험 직업군 종사자들에서 감염된 소와의 직접 접촉을 통해 주로 발생하고 있는 브루셀라증의 임상종상은 국외에서 발생하는 경우와 유사한 양상을 보이고 있으며 치료에 대한 반응은 비교적 좋은 편이긴 하나, 추후 보다 많은 환자들을 대상으로 한 연구가 필요하리라 사료된다. 사람 브루셀라증의 조절을 위해서는 소 브루셀라증의 조절이 필수적이며, 브루셀라증의 조절에 성공한 선진국의 사례를 적극적으로 도입해야 할 것으로 생각된다. Background : Since the first Korean case of human brucellosis was reported in 2002, the incidence of human brucellosis has been rapidly increasing. We performed this study to evaluate the clinical characteristics of human brucellosis occurring in South Korea. Materials and Methods : Demographic features, clinical manifestations, and therapeutic outcomes of cases confirmed as brucellosis according to WHO diagnostic criteria were evaluated. Species of Brucella isolates were identified with 16S rRNA gene sequencing method. Serologic diagnosis was performed with standard tube agglutination test (STA). Results : A total of 34 cases were enrolled from 2003 to 2006 in six hospitals. Eight cases were confirmed with the isolation of Brucella from blood and 26 cases were confirmed with titer of antibodies ≥1:160 by STA. Male (31) was predominant and most of the patients were cattle farmers. The most common transmission route was direct contact with infected or their cattle byproducts. Fever was the most prominent symptom and fatigue followed. Gastrointestinal and musculoskeletal systems were commonly complicated. Patients were treated with doxycycline and rifampin or aminoglycosides for more than 6 weeks. All patients responded well to the therapeutic regimens, but one patient relapsed 10 months after treatment. Conclusion : Brucellosis occurring in Korea has been caused by B. abortus, whose preferred natural host animals are cattle. Korean patients were infected through direct contact with bovine brucellosis. Clinical manifestations of brucellosis were similar to those occurring worldwide. Therapeutic outcomes were good among patients with brucellosis in Korea. In order to prevent human brucellosis, measures to eradicate bovine brucellosis should precede.

The cause of Parkinson's disease (PD) is largely unknown. However, free radical toxicit? may plaf a role ip. the degeneration of substantia nigra, which is the Hajorfocus of pathological damages in PD. Recently, a neuroprotective effect of nicotine in PD has been suggested. Therefore, the mechanism of neurodegenerafion and protective potential o( nicotine in PD were investigated in the experimental modeB of Pll using a neurotoxin, C57BL/6mice were administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg,j.p.). The degree of neurodegenerafion was determined by immunohistochemical stainiHB oftyrosine hydroxylase (TH). TH-positive cells on nigral sections were found 56.0 ±4, 57.9 ±6,52.315ce11s, 49.0±3cells, and 39,4±Scells at days 1, 2, 3, 4, 5, respectively (controls : 57.6±Scells). Hoechst and TUNEL staining showed no evidence of apoptosis. The exandnation on themice co-adrunistered with nicotine(0.2mgAg) and MPTP(30mgag) revealed a tendency ofnicotine protective effects. At days 4 and 5, the degree of TH-positive cells was decreased by20-30%, In corclusiffn, the role of apoptosis was not evidenced in this MPTP modeB of PB.The possible proteccon by nicotine should be elucidated with further studies.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease (PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board (IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: < 25 months and ≥ 25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of < 25 months group (66.9 ± 8.0 yr) was significantly higher than that of ≥ 25 months group (62.2 ± 8.8 yr) (p < 0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in < 25 months group and the amounts of alcohol consumption were significantly higher in ≥ 25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in < 25 months group (p < 0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

Helicobacter pylori is a Gram-negative bacterium which causes chronic gastritis and is associated with gastric ulcer, duodenal ulcer and gastric carcinoma. In the process of screening of antibacterial activities against H. pylori from soil microorgani는, fungus No. 60686 was isolated. After fementaion of No. 60686, the antibacterial compound was isolated, purified and followed by extraction of mycelium with orgainic solvents, acetone and ethyl acetate, through silica gel chromatography, LH-20 gel chromatography and HPLC. As a result of the structural analyses of the compound by IR, ^1H- and ^13C-NMR, FAB/Mass spectrophotomer, the compound having the antimicrobial activity was idenfitied as chaetoglobosin A (C_32H_36N_2O_5), a cytochalasan derivative. The antimicrobial activity of chaetoglobosin A was tested against Gram-positive and negative bacteria by paper disk method. Among the test strains of 9 Gram-positive bacteria and 18 Gram-negative bacteria containing 4 H. pylori strains, the growth of 4 H. pylori strains and 3 S. aureus strains (SG 511, 285 and 503) was only inhibited by chaetoglobosin A. Also it was shown that its growth inhibition against H. pylori strains was stronger than that against S. aureus strains at the treatment of the same concentration. Therefore it was concluded that chaetoglobosin A has a specific growth inhibition against H. pylori of the tested bacteria.
