국내 Fabry disease 환자의 a-Galatosidase A 유전자 돌연변이 검색

박기범,최지혜,강윤성,김선미,정향민,문영준,이광호 中央大學校 基礎科學硏究所 2001 基礎科學硏究所 論文集 Vol.15 No.-

Fabry disease(FD) is an X-linked recessive lysosomal disorder caused by a deficiency of a-galactosidase A(a-Gal A), localized at Xq22. Besides onset of pain and paresthesias in the extremities, FD was diagnosed by absence of a-Gal A activity. In this experiment the a-Gal A activity of Korean FD patients was spectrometrically analysed using an artificial substate, 4-Mrthylumbellifery1-a-D-galactoside. As expected, no a-Gal A activity was detected in lymphocytes and lymphoblastoid cells from FD patients. To screen the mutation in their a-Gal A genes, we performed single strand conformation polymorphism(SSCP) and PCR-direct sequencing form seven a-Gal A exons. The nonsense mutation was identified both in classically affected hemyzygotes and a heterozygote. They showed the C to T transition at nucleotide number 11,002, resulting in a arginine-to-stop(R342X). This result will be applicable for pre- and neonatal detection of FD and to define the genotype/phenotype correlation.

이지범,김민,이승철,원영호,김영표 대한의진균학회 2000 대한의진균학회지 Vol.5 No.3

Background: Sporotrichosis is a common deep cutaneous fungal disease caused by Sporothtix (S.) schenckii. The recent development of polymerase chain reaction (PCR) technology, in particular, arbitrarily primed PCR (AP-PCR) or random amplified polymorphic DNA (RAPD), has greatly enhanced the molecular detection and identification of various pathogenic agents, including fungi. Objective: This study was aimed to differentiate Sporothrix schenckii, and related fungi such as S. schenckii var. luriei, S. flocculosa, S. nivea, Ophiostoma stenoceras, and clinical isolates on the basis of distinct DNA band patterns in the RAPD. Methods: S. schendcii, S. schenckii var. luriei, S. flocculosa, S. niveㅁ, Ophiostoma stenoceras from ATCC and KCCM, and clinical 10 isolates from Chonnam University Hospital were used for RAPD analysis. For RAPD, 3 random primers were used. Genomic DNA was extracted by Liu method. Amplification reactions were performed in volumes of 50 μL containing 10 mM Tris-HCI (pH 8.3), 50 mM KCl, 1.5 mM MgCl2, 0.1% Triton X-100, 200μM dNTP mixture, 40 pM primer, 1 U of Taq polymerase, DNA 20 ng. Results: 3 decamers (5'-TGCCGAGCTG-3', 5'-AGTCAGCCAC-3', 5'-AATCGGGCTG-3') are generated in the RAPD, distinct DNA products from S. schenckii forming characteristic band patterns upon gel electrophoresis. Each random primer amplified characteristic same band patterns in DNA from clinical 8 isolates among 10 isolates, 2 isolates have different DNA band patterns. These results suggest of being a Sporothrix anamorph different from S. schenckii in Korea. Conclusion: With 2 random primers (5'-TGCCGAGCTG-3', 5'-AGTCAGCCAC-3') S. schenckii and related fungi investigated produced distinct DNA band patterns on gel electrophoresis. The RAPD was a very valuable laboratory method for identification of S. schenckii isolates. [Kor J Med Mycol 5(3): 113-119]

정범석,이철,이지현,서민경,한오수,김창윤 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.4

연구목적 : 가임기 여성의 75%가 하나 이상의 월경전기 증상을 경험하며, 일상생활에 지장을 주는 경우도 3∼8%에 이르지만 한국 여성을 대상으로 한 월경전기 증후군(Premenstrual syndrome : PMS)및 월경전 불쾌기분장애((Premenstrual dysphoric disorder : PMDD)에 대한 역학 조사는 부족한 실정이다. 따라서 본 자들은 한국에서의 유병율, 증상의 양태 및 삶에 미치는 정도 등의 역학 조사를 통해 월경전 불쾌기분장애에 대한 올바른 정보를 제공하고 관련 임상 연구의 기초자료로 활용하고자 본 연구르 시행하였다. 방 법 : 6개의 서울 소재 4년제 여자대학교에서 무작위 군집표본 추출로 선택된 4개 학교의1∼3학년 학생 중 무작위 군집표본추출을 통해 선택된 1419명을 대상으로 하였다. DSM-IV진단기준을 근거로 저자들이 제작한 6점 척도의 설문지가 사용되었으며, 난포기에 비해 황체기에 75%이상 악화된 경우 증상이 있다고 판정할 경우의 월경전 불쾌기분장애의 유병율을 조사하였다. 월경전 불쾌기분장애 집단과 증상은 있으나 진단기준에 부합되지 않는 월경전기 증후군 집단으로 나누어 증상 양태, 식습관 변화, 생활에 미치는 영향 정도 등을 비교하였다. 결 과 : 부적절한 자료 198명(13.9%), 주요 신체 혹은 정신질환을 앓은 경우 등 선정 배제 기준에 속하는 경우 348명(24.5%)을 제외한 873명이 최종 분석되었다. 873명 중 월경전 불쾌기분장애의 유병율은 5.0%이었으며, 월경전기 증후군의 유병율은 83.3%이었다. 가장 흔한 증상은 월경전기 증후군 집단의 경우 신체증상(54.6%)이었고, 월경전 불쾌기분장애 집단의 경우 '지속적으로 짜증난다'(95.5%)이었다. 월경전 불쾌기분장애 집단의 88.6%에서 증상 때문에 한 달에 1∼2회 이상 일이나 공부에 지장이 초래되었다. 결 론 : 한국 여자대학생 집단이 경험하는 월경전 불쾌기분장애의 유병율과 증상 양상은 외국과 비슷하다. 아울러 월경전 불쾌기분장애 집단은 월경전기 증후군 집단에 비해 기분 증상이 더 흔하고 심하는 점에서 월경전 불쾌기분장애는 월경전기 증후권과 구별되는 하나의 질환 상태임을 시사한다. Objects : More than 75% of women have been reported to experience premenstrual symptoms and three to eight percent of them suffer from premenstrual dysphoric disorder(PMDD). But little is known about prevalence of premenstrual syndrome(PMS) and PMDD and PMS in Korean women who sttended universities at the time of survey. Methods : One thousand four hundred and nineteen subjects were randomly selected with cluster sampling methods among four women's university in Seoul. We measured the severity of premenstrual symptoms using six-point rating scale developed by the authors on the basis of the research criteria for PMDD in DSM-IV. Premenstrual worsening of symptoms was defined as increase in symptom scores of more than 75% from follicular to luteal phase score. And also, we compared characteristic symptoms, eating behaviors, and functional impairments between PMS and PMDD. Results : After excluding inadequate data according to our exclusion criteria, 873 of 1419 subjects(61.5%) were included in the estimation of the prevalence of PMS and PMDD. Each prevalence rate of PMS and PMDD was found to be 83.3% and 5.0% on the basis of 75% change method respectively. The most frequent symptom was physical symptoms such as headache or breast tenderness(56.4%) in PMS and 'felt irritable'(9.5%) in PMDD. Of the 44 subjects with PMDD, 39(88.6%) reported to have experienced the impairment in work or school at least once per month because of premenstrual symptoms. Conclusions : Our results indicate that prevalence and symptoms of PMDD in Korean university women are similar to those in western culture. The finding that mood symptoms were more frequent and severe in PMDD than in PMS implies that the former may be a disordered condition to be distinguished from the latter physiologic one.

강혜련,김신우,배기범,박지현,강영모,이종명,김능수 대한감염학회 2001 감염 Vol.33 No.3

PFAPA (Periodic Fever, Aphthous stomatitis, Pharyngitis, and cervical Adenitis) syndrome has characteristic features of an early onset, periodicity (interval <4 weeks), and a brisk rising high fever (>39℃) of 3 to 6 days' duration without signs of infection. An 18-year-old male was admitted for high fever, sore throat, headache, and abdominal pain. He had suffered from periodic fevers associated with pharyngitis and cervical adenitis for 14 years without any evidence of infection. The fever recurred approximately every 4 weeks lasting 4 to 7 days with intervening asymptomatic periods. Physical examination was unremarkable except for slightly injected tonsils. Most laboratory tests including CBC were normal except for elevation of Creactive protein level (3.47 mg/dL). Bacteriologic and radiologic studies were negative. The fever was spontaneously subsided in 6 days. To our knowledge, this is the first case report of PFAPA syndrome in Korea. (Korean J Infect Dis 33:219∼222, 2001)

Objectives : The purpose of this study was to investigate the regional differences of the basal ganglia volume between the boy subjects who have Tourette's disorder and the control group who don't have this disorder by using Brain MRI. Methods : Sixteen subjects who were diagnosed as Tourette's disorder using DSM-IV criteria, and sixteen healthy subjects were selected. For analysis the coronal slice images of the basal ganglia were collected and collected MR images were analyzed with NIH Image (version 6.1 ppc). Resuls : The total brain volume in the subjects with Tourette's disorder were smaller than control group by 6.2% (F=6.2, d.f.=1, P=0.019). The right putamen volume in boys with Tourette's disorder were significant smaller than control group statistically (F=3.2, d.f.=3, P=0.040). The asymmetry (1eft>right) in the globus pallidus decreased significantly in the boys with Tourette's disorder (p=0.06) were found from this experiment. Conclusion : These findings suggest that boys with Tourette's disorder may have neuropathological abnormalities in the basal ganglia. Moreover, the present findings point out the important role of basal ganglia, especially putamen, in Patho-physiology of Tourette's disorder. More studies about the structural and functional analysis of the basal ganglia in Tourette's disorder are highly required.

Background: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that is a refractory disease which may cause a deleterious effect on patiets quality of life (QOL). Objective: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the chandes of QOL after treatment. Methods: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after sytemic antifungal treatment. Responses to the questionnaire were scored by 5-point scale (1∼4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptorn and functional impact, patients views concerning treatment, and relationship with doctor. Results: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS : from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients view concerning treatment (AS: from 1.34 to 1.02). 4. The drgree of patients satisfaction at the therapeutic effect was very high- 62.4% (immediately after treatment) and 65.8% (9 months affer initiation of treatment) of patients answered excellent or good. Conclusion: This study confirms that toenail onychomycosis has significant impact on the overall QOL of patients. Also the effect of antifungal therapy on patients QOL were watisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis. [Kor J Med Mycol 3(1): 115∼124]
