Anticonvulsant hypersensitivity syndrome is a rare but fatal complication. It manifests as fever, skin rash, lymphadenopathy, and hepatitis. Phenytoin, phenobarbital, and carbamazepine are the most frequently involved drugs. We here report a case of phenytoin-induced anticonvulsant hypersensitivity syndrome. A 37-year-old woman presented with fever and generalized skin rash, 3 weeks following commencement of phenytoin 400mg daily for treatment of seizure after superficial temporal artery-middle cerebral artery(STA-MCA) anastomosis for moyamoya disease. Her temperature was $39.3^{\circ}C$ and her face was edematous. Laboratory findings showed elevated hepatic enzymes and eosinophilia. Blood and urine culture were all negative. Initially, prednisolone was commenced at 30 mg daily. But fever and skin rash did not improved and hepatic function was more aggravated. After increasing dose of steroid(methylprednisolone 125mg/day), fever and skin rash disappeared and hepatic enzymes returned to normal range.

섬모충플랑크톤은 크게 두 분류군, 세포가 피갑(lorica)에 에워 쌓여 있는 유종섬모류(tintinnids)와 피갑(lorica)이 없는 소모류(oligotrichs)로 대별하고 있다. 국내에서 해양 섬모충플랑크톤의 분류학적 연구는 비교적 종 동정이 용이한 유종섬모류를 대상으로 먼저 시작되었고, 분류기준인 피갑의 가변성 때문에 분류학적 문제점은 있으나, 현재까지도 주로 피갑의 형태적 특징에 따라 종을 구별하여 생태·생리학적 연구정보로 활용하고 있다. 반면, 소모류의 경우, 세포염색을 통한 섬모열의 정밀한 특징으로 종을 구별하는 어려움으로 인해, 소모류의 분류학적 연구는 2000년 이후에 비로소 국내에 소개되었다. 최근 분석기술의 발달과 더불어 섬모충의 분류체계와 종 정보에도 많은 변화가 생겼고 이를 반영하여 국내 해양에서 출현하는 주요 섬모충플랑크톤 종류가 새롭게 정리되어 도감으로 출간되었다. 섬모충플랑크톤은 동물플랑크톤의 질 높은 먹이원이 되는 동시에 초미소(pico)와 미소(nano)플랑크톤의 포식자로서 해양 미세먹이망에서 중요한 중간 역할을 하고 있다. 이러한 부유생태계에서 섬모충플랑크톤의 역할은 새로운 주제가 아닌, 현재는 해양생태학의 보편적 지식으로 공유되고 있다. 따라서 해양 섬모충플랑크톤의 현장 모니터링 방법과 실험실 분석의 과학적 타당성을 기반으로, 획득된 자료로써 그 신뢰성을 확보함은 국내 섬모충플랑크톤 연구 발전에 크게 일조하리라 기대된다. 섬모충플랑크톤 연구 경험을 바탕으로 유종섬모류 동일종의 피갑변이, 세포염색에 의한 소모류의 정량·정성분석, 유전자 분석결과의 자료비교, 생태학적 정보비교, 섬모충플랑크톤 현장채집 방법을 제안하며, 현실적 수용가능 범위를 설정하여 섬모충플랑크톤 모니터링의 정도관리를 위한 연구자들의 관심을 유도하고자 한다. Marine planktonic ciliates include two major groups, loricated tintinnids and naked oligotrichs. The study of marine ciliate plankton in Korea began with taxonomic efforts on tintinnids based on the morphology of lorica, a vase-shaped shell. Despite polymorphism in the lorica, it is utilized as a key characteristic in identification of tintinnid species. However, oligotrichs have been studied only recently in Korea due to challenges associated with the observation of ciliary arrangements and the technical development for cell staining. Species diversity and phylogenetic classification of the ciliates have been informed by recent advances in morphological and molecular analyses. Illustrations of the planktonic ciliate in Korea have been published on the basis of taxonomic data of tintinnids and oligotrichs. Planktonic ciliates acting as the major consumers of pico- and nanoplankton as well as the prey of mesozooplankton, has been monitored by spatial and temporal investigations in Korean coastal waters. A practical approach addressing the limitations and potential of marine ciliate studies in Korea is proposed here to improve the data quality of planktonic ciliates, providing an enhanced basis for quality control of ciliate monitoring.

In vitro AM extract(1mg/ml) inhibited melanin biosynthesis and are useful for the material used in cosmetics. B16 mouse melanoma cells were cultured in different concentrations. The non-cytotoxicity of the plant extracts was confirmed by MTT assay.

유방에 발생한 에크린 선단공한산종의 세침흡인 세포소견 -관암종으로 오인한 1예 보고-

김영옥,전창완,장희경,Kim, Young-Ok,Jeon, Chang-Wan,Chang, Hee-Kyung 대한세포병리학회 2005 대한세포병리학회지 Vol.16 No.1

Eccrine acrospiroma is a rare adnexal tumor of the skin. When the clinical presentation is that of a breast lump, diagnosis can be difficult. Also, most of the cytopathologists are not familial with the cytologic features of this tumor and this is responsible for diagnostic pitfalls. We experienced a case of eccrine acrospiroma of the right breast in a 41-year-old female, misdiagnosed by fine needle aspiration cytology (FNAC). FNAC was characterized by tight clusters or sheets of small round cells, polygonal cells, and spindle cells and tubule like structures within clusters. Myoepithelial cells were not noted in the clusters. The diagnosis of eccrine acrospiroma was confirmed by histology.

목 적 : 한 나라의 건강 지표로 중요한 의의를 갖는 영아 사망의 2/3는 신생아기에 일어나며 주로 저출생 체중아에 의한 것이다. 최근 신생아 집중치료의 발달로 1,500 gm 미만의 극소 저출생 체중아의 생존율이 향상되는 추이여서, 본 연구는 1996년 부터 2001년까지 6년간 전남대학교병원에서 극소 저출생 체중아의 발생 빈도와 생존율 및 이환율 변화를 알아보고자 하였다. 방 법 : 본 연구는 1996년 1월부터 2001년 12월까지 전남대학교병원 신생아 집중 치료실에 입원했던 1,500 gm 미만의 극소 저출생 체중아 565명을 대상으로 하였다. 1996년부터 1998년까지를 전반기, 1999년부터 2001년까지를 후반기로 나누어 기간별 VLBWI의 생존율, 이환율 및 입원 기간의 차이를 비교하였고, 이를 또한 출생 체중과 재태 연령별로도 비교하였다. 생존 환아에서의 이환율은 '단기 질환'과 '장기 질환'으로 질환을 구분하여 비교하였고, 원내 출생아에서의 VLBWI 발생 빈도 및 기간별 변화, 기간별 주산기 인자와 생존율과의 상관관계, 사망 원인에 대해서도 조사하였다. 결 과 : 원내 출생 VLBWI의 발생 빈도는 총 8.3%이었으며 전반기 6.0%, 후반기 11.0%로 후반기에 그 빈도가 증가하였다. VLBWI 총 생존율은 76.8%이었으며, 전반기(71.8%)에 비해 후반기(80.1%)에 향상되었고, 특히 출생 체중 1,000-1,249 gm과 재태 연령 28-30주에서 개선되었다. 주산기 인자 중 후반기에 제왕 절개 분만이 증가하였고, 다태아에 비해 단태아일 경우, 질식 분만에 비해 제왕 절개 분만일 경우에 생존율이 증가하였다. 사망의 빈도는 생후 7일 이전 사망이 전체 사망의 58.8%로 가장 빈번하였다. 사망 원인으로는 신생아 호흡 곤란 증후군이 주요한 원인이었고, 패혈증, 폐출혈 빈도순이었다. 이환율은 전반기(82.5%)에 비해 후반기(92.3%)에 유의하게 증가하였다. 생존한 환아에서 전반기에 비해 후반기에 총 이환율과 단기 이환율은 증가하였으나 장기 이환율은 통계학적으로 유의한 차이가 없었으며, 출생 체중 1,000-1,499 gm과 제태 연령 28-33주에서는 단기 이환율이 유의하게 후반기에 증가한 반면 오히려 장기 이환율은 감소하였다. 생존 환아에서 평균 입원 기간은 전반기에 비해 후반기에 유의하게 연장되지는 않았다. 결 론 : VLBWI의 빈도가 증가하고 생존율이 향상된 반면 이환율은 증가되었다. 그러나, 출생 체중 1,000-1,249 gm과 재태 연령 28-30주에서 현격한 생존율 증가와 함께 '단기 이환율'은 증가되었으나 오히려 '장기 이환율'은 감소하였다. Purpose : The survival rate of very low birth weight infants(VLBWI) has improved by virtue of specialized neonatal care. This study was performed to analyze the changes in incidence, survival rate and morbidity of VLBWI who admitted to Chonnam National University Hospital from 1996 to 2001. Methods : We enrolled 565 VLBWI, and compared the incidence and the survival rate according to the birth weight or gestational weeks between period I(1996 to 1998) and period II(1999 to 2001). The mortality rate according to the postnatal age, cause of death, morbidity and days of hospital stay were also compared. Morbidity is categorized into 'short term' which is curable until discharge, and 'long term' causing any types of sequelae after discharge. Results : Incidence of VLBWI significantly increased in period II over period I(6.0% vs. 11.0%, P< 0.001). The survival rate also increased in period II(71.8% vs. 80.1%, P<0.05), especially in 1,000 to 1,249 gm of birth weight(P<0.001) and in 28 to 30 weeks of gestation(P<0.001). The most common cause of death was respiratory distress syndrome in period I; however it was sepsis in period II. Although overall and short term morbidity rate increased, long term morbidity and days of hospital stay didn't increase in period II. Conclusion : Although the incidence of VLBWI significantly increased and the survival improved in period II compared to period I, especially in 1,000 to 1,249 gm of birth weight and 28 to 30 weeks of gestation, 'long term' morbidity rate and hospital days didn't increase.

Shewanella sp. Ke75 Esterase with Specificity for p-nitorphenyl Butyrate: Gene Cloning and Characterization

김영옥,김형권,In-Suk Park,남보혜,Hee Jeong Kong,김우진,Dong-Gyun Kim,김봉석,Young-Ju Jee,송정헌 한국응용생명화학회 2013 Applied Biological Chemistry (Appl Biol Chem) Vol.56 No.1

A bacterial strain that produces a cold-adapted esterase was isolated from tidal flats and identified as Shewanella sp. Ke75. In the present study, the corresponding gene was cloned using the shotgun method. The amino acid sequence deduced from the nucleotide sequence (957 bp) corresponded to a protein of 318 amino acid residues with a calculated molecular weight of 34875 Da. The esterase showed 68 and 57% identities with the putative esterases of Shewanella amazonensis SB2B and Colwellia psychrerythraea 34H, respectively. The esterase contained a putative leader sequence, as well as the conserved catalytic triad (Ser, His, Asp), consensus pentapeptide GXSXG, and oxyanion hole sequence (HG). The protein Ke75 was produced in both soluble and insoluble forms when Escherichia coli cells harboring the gene were cultured at 30oC. The enzyme showed specificity for C4 (butyrate) as a substrate, with little activity toward the other p-nitrophenyl esters tested. The optimum pH and temperature for enzyme activity were pH 9.0 and 30oC, respectively. Relative activity remained up to 60% even at 5oC with an activation energy of 6.29 kcal/mol, which indicated that it was a cold-adapted enzyme. Enzyme activity was enhanced in the presence of Mn2+ ions, but inhibited by Cd2+, Cu2+, Hg2+, and Zn2+ ions.

This study was to analyze the research trend related to mathematics education evaluation in the analysis of the articles on <National mathematics education journal>, <Korea mathematics education journal>. The study explores the future direction of mathematics education assessment research by investigating whether such evaluation was suitable for the expectation about the assessment required in the current mathematics curriculum. This study was to classify the evaluation-related researches based on Korea educational curriculum revision from 1991-2010 to examine the research trend on the mathematics education evaluation in each season in Korea, analyze the articles by 'monitoring of student's progress', 'judgement on instruction', 'giving the value on mathematics achievement of students', 'value judgement of the program' that were the purpose of evaluation presented in 1995 NCTM(National Council of Teachers of Mathematics). As a result, looking at the research trend classified by the time of the educational curriculum revision, the 7th educational curriculum had the most number of the papers announced from 1997-2006. Despite 2007 educational curriculum revision was the short period from announced 2007-2008 before the next educational curriculum was placed, 11 papers(34.4%) were published. According to the category by the purpose of the assessment prescribed in NCTM, it showed that researches of 'monitoring of student's progress(46.9%)' were the most, those of 'value judgement of the program' and 'giving the value on mathematics achievement of students had a similar percentage.

미국 Common Core State Standards for Mathematics 소개

김영옥,Kim, Young-Ok 영남수학회 2011 East Asian mathematical journal Vol.27 No.4

The purpose of this study is to introduce the Common Core State Standards (CCSS) for mathematics which is released on June 2, 2010 in the U.S.A. The common core state standards are aligned with college and work expectations, and include rigorous content and application of knowledge through high-order skills. The most distinguishable differences between the CCSS standards and the NCTM standards are that the CCSS standards considers the mathematical modeling as one of the mathematical content domains such as algebra, geometry, ets, and the standards are designed by working together with school leaders of all states.
