연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

A C++ based computer program for the design of composite steel-concrete box girder by the LRFD method is developed. The program consists of a main program, a header program, and 16 function programs. The load analysis for live and dead loads is performed by using the influence line based on the 3-moment method. For the design of box girder, strength limit states, fatigue limit state, and service limit state are considered. In addition, the constructibility of the girder is also checked. The validity of the program is demonstrated by comparing the design result for 3-span continuous box girder by the present program with the one by hand-calculation.

The volatile organic compounds (VOCs) have been recognized as major contributor to air pollution. The catalytic oxidation is one of the most important processes for VOCs destruction clue to getting high efficiency at low temperature. In this study, mono metallic Pt and bimetallic Pt-Ru were supported to TiO₂ and γ-Al₂O₃. In order to distribute metals uniformly, Xylene, toluene and MEK were used as reactants. The mono metallic or bimetallic catalysts were prepared by the excess wetness impregnation method and were characterized by XRD, XPS, TEM and BET analysis. As a result, Pt-Ru bimetallic catalysts were showed higher conversion than Pt mono metallic catalyst. Pt-Ru bimetallic catalyst was showed highest conversion on the γ-Al₂O₃support. In the VOCs oxidation, Pt-Ru bimetallic catalyst had multi point active sites, so it improved the range of Pt metal state. Therefore, bimetallic catalysts were higher conversion of VOCs than mono metallic ones.

Noise cause is dividing to fluid noise by exhaust flow of fan and vibration noise by rotational vibration of motor. Until now, measuring method has been used to measure vibration by the accelerometer, this method has been not measured for the vibration in some parts of brush and commutator because of motor construction. This research was purposed on the accurate analysis, using laser vibration analyzer, of noise cause against the difficult part in old times. By using this measured data, we would like to use for the design of silent motor.

김용구,이민수,김 인,곽동일,서광윤 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.3

연구배경 : 정신분열병이 유전적이라고 제시하는 많은 역학 연구와 유전자 연구에도 불구하고, 이 질환의 유전방식과 질병유전자는 밝혀져 있지 않다. 본 연구에서는 정신분열병과 22번 염색체 장완의 11.2-12부위에 위치한 Interleukin-2수용체 β chain 유전자간에 유전적 연합을 조사하고자 정신분열병 환자 93명과 정상대조군 97명 대상으로 중합효소연쇄반응을 이용하여 Interleukin-2 수용체 β chain (IL-2Rβ) 유전자의 다형성 분포를 조사하였다. 연구방법 : 환자군은 DSM-Ⅲ-R 진단기준에 따라 임상아형(망상형, 붕괴형, 미붕괴형, 잔류형)으로 분류하였다. 음성 및 양성 정신분열병으로 분류하기위해 Positive and Negative Syndrome Scale(PANSS)을 사용하였다. Genomic DNA를 전혈 임파구에서 추출한 후, IL-2Rβ 유전자좌를 분석하기 위해 dinucleotide(GT)n 염기배열순서를 중합효소연쇄반응을 이용하여 증폭시켰다. 연구결과 : IL-1Rβ의 대립유전자는 모두 8가지 종류이고, guanine-thymine의 반복된 149 염기쌍을 시작으로 151, 153, 155, 157, 159, 161, 163 염기쌍의 형태를 보였다. 정신분열병 환자군과 정상대조군간에 도형접합체 및 이형접합체 빈도의 유의한 차이는 없었다. 환자군과 정상대조군의 대립유전자 분포의 빈도는 통계적으로 유의한 차이가 없었다. 더욱이 각각의 대립유전자 분포에서도 양군간 유의한 차이는 없었다. 또한 동질의 아형으로 분류해 보기위해 임상아형, 양성 및 음성증상군, 가족력의 유무에 따라 비교적 동질적인 표현형을 가진 집단으로 나눈 후 대립유전자 분포를 비교해 보았으나 통계적으로 유의한 차이를 보이지 않았다. 결 론 : 본 연구에서는 Interleukin-2 수용체 β chain 유전자가 정신분열병의 병인론에 관련된다는 가설을 지지할 만한 긍정적 소견을 얻지 못했다. Background : While a significant genetic predisposition to schizophrenia has been proposed, the mode of inheritance or nature of etiological factors is unknown. Previous reports of a genome-wide survey for schizophrenia susceptibility genes have indicated a possible region of linkage on chromosome 22. In order to test the possibility that the interleukin-2 receptor β chain(IL-2Rβ) gene on chromosome 22 is of etiological importance in schizophrenia, a case-control association study was conducted. Methods : Subjects were ninety-three schizophrenic patients with a diagnosis of schizophrenia by DSM-Ⅲ-R criteria and ninety-seven normal controls, Schizophrenic patients were divided by clinical phenotypes such as DSM-Ⅲ-R diagnostic subtypes, positive and negative symptoms, and family history so as to increase the homogeneity of schizophrenics. Genomic DNA was extracted from whole blood lymphocytes according to standard procedures. The DNA was used to study a dinucleotide repeat in the IL-2Rβ gene. To reveal the dinucleotide polymorphism. genomic DNA of subjects was amplified by polymerase chain reactions(PCR). Results : At the IL-2Rβ gene locus, all the previously reported alleles(eight different alleles) of a dinucleotide polymorphism were identified. There was no significant difference between number of heterozygosity in schizophrenic patients and in normal controls. There was no significant difference in the distribution of frequencies of alleles between schizophrenics and normal controls. In addition, there was no significant difference in the allele frequencies among subtypes of schizophrenic patients according to DSM-Ⅲ-R diagnostic subtypes, positive and negative symptoms, and family history. Conclusion : The present study did not detect a difference in frequencies of alleles of a dinucleotide polymorphism at the IL-2Rβ gene locus between schizophrenic patients and normal controls. These results do not supports an evidence that IL-2Rβ gene plays, a major role in the etiology of schizophrenia.
