박준수,공도연,박경배,민용식,김영창,정순이,이혜경 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.2

목적 : 가와사끼 병의 뇌파 소견 및 다른 임상인자들과의 연관성을 알아보고자 하였다. 방법 : 1994년 1월부터 1995년 12월 사이에 순천향대학 천안병원 소아과에 입원한 23명의 신경학적으로 정상인 가와사끼 병 환아에게 뇌파검사를 실시하여 이를 검사시기, 성별, 연령, 혈소판, 간기능 검사치, 그리고 동맥류 유무등의 임상인자들과 비교하였다. 결과 : 이상뇌파가 23명중 52.2%인 12명에게서 관찰되었으며, 이상뇌파로는 예파 및 극파, 극·서파 복합 양상과 전반적인 배경파의 서파양상이 나타났다. 뇌파의 검사시기가 진단부터 1주 이내인 경우에 이상뇌파의 빈도가 그 후보다 의미있게 높았으나, 그 밖의 다른 임상인자와의 연관성은 별 의미가 없었다. 결론 : 가와사끼 병 초기에 이상뇌파가 나타나는 것은 비록 신경적 증상은 없지만 중추 신경계가 영향을 받는다는 간접적인 증거로 생각할 수 있어 향후 신경적 합병증 발생 여부에 대한 면밀한 관찰이 필요하다고 생각된다. Purpose : This study is to find out if there is any association between EEG abnormalities in Kawasaki disease with other clinical factors. Methods : We performed EEG in 23 Kawasaki disease patients without any neurologic sign who admitted in Soonchunhyang Chunan Hospital from 1994. 1. to 1995. 12. and compared it with sex, age, platelet count, liver function test and presence of coronary artery aneurysm. Results : Abnormal EEG findings were observed in 12 of 23 patients(52.2%) and as for abnormal EEG findings, sharp, spike, spike & slow wave complex, and generalized slow background activity were noted. When EEG was performed within a week after the diagnosis, the incidence of abnormalities of EEG increased significantly but there was no correlation with other clinical factors. Conclusion : EEG abnormalities in the early stage of Kawasaki disease indicate that although there is no abnormal neurologic signs clinically, central nervous system might be affected and there should be a close observation for the developement of neurologic complication.

박경배,민용식,박준수 순천향의학연구소 1998 Journal of Soonchunhyang Medical Science Vol.4 No.2

Purpose: Idiopathic or immune thrombocytopenic purpura(ITP) is a common childhood illness characterized by thrombocytopenia secondary to shortened platelet survival. Medical therapy includes corticosteroids, intravenous immune globulin (IVIG), and IV Rho(D) immunoglobulin (anti-D). Individuals with Rh-negative blood generally do not respond to treatment with anti-D, but little information is currently available regarding the potential relationship between blood type and response to IVIG. This study was designed to characterize the relationship between ABO and Rh blood type and the response to IVIG in children and adolescents with newly diagnosed ITP. Patients and Method: A retrospective chart review was performed for 31 patients with newly diagnosed ITP initially treated with IVIG by the Department of Pediatrics at Soonchunhyang University Hospital in Seoul and Chunan, Korea. Results: There were no significant differences in response rate or clinical outcome by ABO blood group in children with ITP who received IVIG monotherapy as their initial treatment. However we could not evaluate the effect of Rh type on the reponse to IVIG because our all patients were Rh positive. Conclusion: ABO blood group does not appear to be prognostic factors when IVIG monotherapy is the initial treatment for childhood ITP.

칠절봉 신갈나무림의 군락구조와 토양환경과의 관계를 파악하기 위해 식물사회학적 조사와 토양 환경을 분석하였다. 조사지역의 신갈나무림은 신갈나무군락, 철쭉꽃하위군, 큰개별꽃하위군으로 구분되었으며, 철쭉꽃하위군과 큰개별꽃하위군에서의 방형구당 평균출현종수는 각각 30종(24∼46종), 43종(31∼52종) 이었다. 피복지수치에 의한 계층별 우점순위는 교목층에서 신갈나무(6750.0), 아교목층에서 당단풍(2364.0) 관목층에서 철쭉꽃(988.5), 초본층에서 쌀새(1040.5)가 가장 높게 나타났다. 신갈 나무림의 DBH 분포는 2∼10㎝ 범위의 소경목이 전체의 29.7%를 차지하였으며 전체적으로 정규분포를 나타내어 교란 후 재생과정에 있는 것으로 조사되었다. 또한 후계목의 발달로 인한 극상상태로의 천이가 가능할 것으로 조사되었다. 전반적인 토양환경은 두 하위군 간에 뚜렷한 차이가 없었으며, 큰개별꽃하위군이 철쭉꽃하위군에 비하여 다소 양호한 것으로 조사되었다. 환경구배분석에서 까치박달, 물푸레나무, 함박꽃나무 등은 습한 곳에 분포하고 철쭉꽃, 전나무, 국수나무 등은 건조한 곳에 분포하는 것으로 나타났다. A relationship between the community structure composition and soil environmental factors of the Quercus mongolica forest on Mt. Chiljelbong was investigated from June 1996 to August 1997. The Q. mongolica community was classified into two subcommunity of Rhododendron schlippenbachii and Pseudostellaria palibiniana. The 30(24-46) species per quadrat were appeared in R. schlippenbachii subcommunity and 43(31-52)species in P. palibiniana subcommunity. The dominant sequences on each stratum determined by the coverage index showed that Q. mongolica was the most dominant in tree-1 layer with 6750.0, Acer pseudo-sieboldianum in tree-2 layer with 2364.0, R. schlippenbachii in shrub layer with 988.5, and Melica onoei in herb layer with 1040.5 value. The value of diameter breast height(DBH) showed a normal distribution displaying a highest value in the range of 2∼10㎝(29.7%) in Q. mongolica forest and it was investigated being at restoration phase after disturbance. It also was investigated that the succession to climax state would be possible due to growth of successive tree. Overall, which the soil conditions make little difference between two subcommunities, P. palibiniana subcommunity was favorable than those of R. schlippenbachii subcommunity. It was shown that in an environmental gradient analysis, Carpinus cordata, Fraxinus rhynchophylla, and Magnolia sieboldii were distributed in a mesic area, but R. schlippenbachii, Abies holophylla, and Stepanandra incisa in a xeric area.

다중 연산을 고려한 XML 문서의 접근제어

The growth in interchange of business and other sensitive data has led to increasing interest in access control. Access control for XML is receiving significant attention as XML is gaining popularity for storing and exchanging information. Until now, research on XML security has been focused on the security of data communication using digital signatures or encryption technologies. As XML is also used for a data representation of data storage, XML security comes to involve not only communication security but also managerial security. In this paper, we discuss an XML access control model and propose a technique that supports not only read operations but also update operations.

국내에서 채집한 진드기에서 중합효소연쇄반응을 이용한 라임병균 및 Ehrlichiosis 원인체의 검출

김종배,엄용빈,박성언,박상욱,김영미,송혜원,안준환 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1998 Journal of biomedical laboratory sciences Vol.4 No.2

국내에서 채집한 진드기의 라임병 및 ehrlichiosis원인체 보균 상태를 조사하기 위하여 총 516마리 (Ixodes spp. 22마리, Haemaphysalis spp. 494마리)의 ixodid 진드기를 봄과 가을에 걸쳐 강원도 고산지대 일원에서 채집하였다. 수집한 진드기에서 DNA를 추출 ·정제한 후 추출한 DNA를 template로 이용하여 , Borrelia burgdorferi sensu lato 및 Ehrlichia spp.에 특이하게 반응하도록 제작한 primer를 이용한 중합효소연쇄반응 (polymerase chain reaction, PCR)을 실시하였으며, 이 결과를 oligonucleotide probe를 사용한 southern blotting을 통하여 다시 확인하였다. 총 516마리의 진드기중 B.garinii sensu lato DNA 양성 인 진드기는 68(13.2%)마리 (B. burgdorferi sensu stricto,2; B. afzelii,1; B. garinii,33; B.tanukii,8; B.turdae, 4)로 나타났으며 이 중 37 (7.2%)마리의 진드기 는 southern blot analysis에서도 양성으로 확인되었다. 또한 101 (19.2%)마리의 진드기가 Ehrlichia spp.에 대한 PCR에서 양성 이었으나, 이들 중 25 (4.8%)마리 만이 southern blot analysis에서 양성으로 확인되었다. 그러나 사람의 병인체로 추정 되는 human granulocytic ehrlichiosis (HGE) agent DNA를 보균한 진드기는 확인되지 않았다. 한편 라임병균과 ehrlichiosis원인체를 동시에 보균한 것으로 밝혀진 진드기가 3마리에서 (0.6%)확인되어,국내에서도 진드기 교상시 이들 두 가지 열성질환이 동시에 감염될 가능성이 있는 것으로 사료됨으로 진드기 매개성 열성질환에 대한 적절한 진단법 등을 보다 체계적으로 연구하여야 할 것으로 판단된다. To investigate the distribution of Borrelia Burgdorferi and human granulocytic ehrlichiosis(HGE) agent in ticks, adult ixodid ticks of Ixodes spp. and Haemaphysalis spp. were collected from the high mountain areas of Kangwon Province. Using DNAs extracted and purified in the collected ticks, polymerase chain reaction (PCR) was performed to amplify the specific nucleotide sequences of both agents. Of the 516 ticks, a total of 68 (13.2%) ticks was positive for Borrelia burgdorferi sensu lato with PCR analysis (2 for B. burgdorferi sensu stricto; 1 for B. afzelii; 33 for B. garinii; 8 for B.tanukii; 4 for B. turdae). However a little more than half of PCR-positive ticks (37/68) was found to be positive in the southern blot analysis with Bl6S oligonucleotide probe. One hundred and one (19.2%) ticks were positive for Ehrlichia spp. in PCR, and a quarter of them (25/101) was positive in southern blot with E16S oligonucleotide probe. But none of them was found to be the DNA of HGE agent. And 0.6% (3/516) ticks were positive for both of B. burgdorferi sensu lato and Ehrlichia spp. These findings might implicate the possibility of the outbreak of lyme borreliosis and ehrlichiosis in Korea, and more extensive studies may be need for the diagnosis of multiple tick-borne diseases.

G+C 함량이 높은 Primer를 사용하는 중합효소 연쇄반응에서 변성제가 미치는 영향

김영미,안준환,김종배,엄용빈 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1996 Journal of biomedical laboratory sciences Vol.2 No.2

G+C 함량이 높은 primer를 이용한 중합효소 연쇄반응을 실시하는 경우 높은 annealing 온도로 인하여 특이 염기서열의 합성정도가 매우 미약하게 나타나는 경우가 많이 있다. 이와 같은 문제점을 보완하기 위하여 glycerol, formamide 및 dimethyl sulfoxide (DMSO) 등의 변성제를 반응용 완충액에 첨가하고 중합효소 연쇄반응을 실시하여 그 결과를 비교 검토하였다. G+C 함량이 낮은 Borrelia burgdorferi의 Ly1 유전자의 primer set인 Bb 679와 Bb 680를 이용한 중합효소 연쇄반응에서는 변성제 첨가에 따른 합성 DNA의 양의 변화가 뚜렷하지 않았다. 그러나 G+C 함량이 높은 primer set인 Mycobacterium paratuberculosis의 IS900 유전자의 IS900/150C와 IS900/921를 이용한 중합효소 연쇄반응을 유도한 경우에는 변성제를 첨가함에 따라 합성된 DNA의 양의 증가가 뚜렷하였으며, 2.5% glycerol과 1.25% formamide를 혼합 첨가한 경우와 또는 2.5% DMSO를 반응용 완충액에 첨가하였을 때 비특이적인 증폭비율이 낮아 특이 염기서열의 합성 결과가 양호한 것으로 나타났다. Poor yields of amplified DNAs could be resulted in polymerase chain reaction(PCR) processes with G+C-rich DNA primers because of their high Tm values. To maximize the yields of amplification in PCR processes with G+C-rich primers, we compared the yields of amplified DNA fragments according to the concentrations of specific denaturants added to the reaction mixture of PCR system. With addition of the mixture of 2.5% glycerol and 1.25% formamide, or 2.5% dimethyl sulfoxide to the reaction cocktail, respectively, remarkable increases in the yields of amplified DNA fragments were not observed in the PCR systems with G+C-low primers of Lyl chromosomal gene from Borrelia burgdorferi but observed in the PCR system with G+C­rich primers of IS900 gene from Mycobacterium paratuberculosis. Although we were not practically able to discriminate the yields of PCR DNAs according to the concentrations used in this study, addition of the mixture of 5% glycerol and 2.5% formamide, or 5% DMSO tended to increase the production of extra bands.
