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.

노영수,정세영,정지창 한국환경독성학회 1998 환경독성보건학회지 Vol.13 No.2

The use of cisplatin is limited by severe side effects such as renal toxicity. Our platinum-base drug discovery is aimed at developing drugs capable of diminishing toxicity and improving antitumor activity. We synthesized new Pt (II) complex analogue [Pt (cis-DACH)(DPPP)]ㆍ2NO₂,(PC) containing cis- l,2-diaminocyclohexane as a carrier ligand and 1, 3-bis(diphenylphosphino) propane as a leaving group. Furthermore, nitrate was added to improved the solubility. In this study, its structure was determined and its antitumor activity against SKOV-3 and NIH-OVCAR-3 human ovarian adenocarcinoma, and in nitro cytotoxicity was determined against primary cultured rabbit kidney proximal tubular and renal cortical cells of human kidney using colorimetric MTT assay. PC demonstrated acceptable antitumor activity against SKOV-3 and NIH-0VCAR-3 human ovarian adenocarcinoma and significant activity as compared with that of cisplatin. The toxicity of PC was found quite less than that of cisplatin using MTT and ³H-thymidine uptake tests in rabbit proximal tubular cells and human kidney cortical cells. PC was used for human cortical tissue in 7 weeks hitoculture by the glucose-consumption tests. We determined that the new platinum drug has lower nephrotoxicity than cisplatin. Based on these results, this novel platinum (Ⅱ) complex compound (PC) represent a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low nephrotoxicity.

강영준,홍성진,강형수,노경완 韓國非破壞檢査學會 1999 한국비파괴검사학회지 Vol.19 No.1

잔류응력은 공학적 구조물에 결함을 야기하는 유해한 응력이므로 산업현장에서는 이를 측정하기 위한 많은 관심을 가지고 있다. 현재 잔류응력 측정은 일반적인 방법을 사용하고 있지만 이러한 방법들은 어느정도 문제점을 내포하고 있다. 그러므로 레이저 스페클 간섭법에 유한요소법과 점 가열법을 혼합하여 산업 현장에 유해한 잔류응력을 측정할 수 있는 새로운 기법을 개발하였다. 이 기법에서 사용된 레이저 스페클 간섭계는 측정 시편의 응력이 풀릴 때의 면내 변형을 측정하기 위해서 사용되어 졌으며, 유한요소법은 응력 풀림을 위한 가열부의 온도와 그 밖의 변수들을 결정하기 위해서 사용되어 졌다. 잔류응력은 측정하고자 하는 부위의 가열 냉각에 의한 변형률에 의해 결정되어지며, 이에 대한 간단한 모델링을 제시하였다. 또한 본 실험은 변형의 3차원 정량화를 수행하기 위해서 레이저 스페클 간섭계의 전자 광학적 기법 중의 하나인 위상이동법을 이용하여 수행되어졌다. Residual stress is one of the causes which make defects in engineering components and materials. And interest in the measurement of residual stress exists in many industries. There are commonly used methods by which residual stresses are currently measured. But these methods have a little demerits, time consumption and other problems. Therefore we devised a new experimental technique to measure residual stress in materials with a combination of laser speckle pattern interferometry. finite element method and spot heating. The speckle pattern interferometer measures in-plane deformations while the heating provides for very localized stress relief. FEM is used for determining heat temperature and other parameters. The residual stresses are determined by the amount of strain that is measured subsequent to the heating and cool-down of the region being interrogated. A simple model is presented to provide a description of the method. In this paper, the ambiguity problem for the fringe patterns has solved by a phase shifting method.

신경베체트병에 의한 신경인성방광 : 증례보고

이길용,임건한,소영석,노준,김철성,장대수 朝鮮大學校 附設 醫學硏究所 2002 The Medical Journal of Chosun University Vol.27 No.2

The co-existence of mouth and genital ulceration with iritis was first defined as a syndrome by Behcet. It is now known to be a chronic and relapsing systemic disease, which involves many other systems. Neurogenic bladder dysfunction due to Behcet's disease, however, is extremely rare, and only a limited number of cases have been reported in the international literature. Voiding disfunction in Behcet's disease can be due to neurological or direct bladder involvement and can be related to bladder and sphmctehc components in both phases of micturition. We report on a 35-year old patient with a neuropathic bladder secondary to Behcet's disease.
