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.

For the development of antifungal agents. modification of naftifine which exhibits significant antimycotic activity was performed by replacing the naphthalene ring of it to hetero cyclic rings such as morpholine. benzothiazole. piperidine and pyridine derivatives. The synthesized compounds were tested in vitro antifungal activity against five different fungi with naftifine as a comparative antimycotic molecule. From the biological evaluation two compounds. (E)-N-(3-phenyl-2-propenyl)-N-(4-piperidinylmethyl)amine(3d) and (E)-N-(3-phenyl-2-propenyl)-N-(3-pyndylmethyl)amine(3D) showed relatively noticeable activity(MIC=50㎍/㎖). On the other hand. the other compounds had no activity.

The 5-Fluorouracil (5-FU) has been used as a synthetic antineoplastic agent with the synthesis of nucleic acid in the cell. Unfortunately this drug is known to cause toxic reaction in normal tissue also. In this experiment, the authors studied the effect of 5-FU on the rat liver histochemically observing the change in the activities of acid phosphatase and adenosine triphosphatase. Healthy albino male rats (Wistar strain) were used as experimental animals which were divided into the control and 5-FU treated groups. All experimental animals were given food and water unlimited. The animals of experimental group were administered 5-FU, in a dose of 50mg per kg of body weight by intraperitoneal injection. The animals of control groups were administered only water for injectio. The experimental animals were sacrificed at 6, 12, 24 and 36 hours after administration of 5-FU, respectively. The liver specimens, sectioned by cryostat were stained by Gomori method and by Wachestein and Meisel method for studying changes in the activities of acid phosphatase and that of ATPase, respectively. The results obtained were as follows: 1. The acid phosphatase activity was increased in the hepatic parenchymal cells of the 5-FU treated rat liver. 2. The adenosine triphophatase activity was decreased in the intralobular bile canaliculi of the 5-FU treated rat liver. Consequently, it is suggested that 5-FU would induce the change in the activities of possibly from production of toxic metabolites and subsequent damage in rat liver.

The study is to do the field survey on the architectural environment of domestic long-term hospitals and to find out how to improve the management of whole facilities. The results from the study are as follows. 1) The optimal capacity of one sick room ranges from three to four persons. A sickroom with a bed is preferable to one with a Korean under-floor heating style sickroom because it is easier to take care of patients and to make patient's private space in the bed-style sickroom. The study showed that most of the hospitals don't have enough space for the patients. 2) The field survey on the facilities reveals that some hospitals have sick rooms and public areas not convenient for wheelchair users to use. It is required to improve the condition as soon as possible. The patient is said to need computer or amusement rooms. Also, it is proposed to run a hospice ward in a hospital. 3) The analysis of co-relation on the environment of hospitals revealed that the environmental condition had a meaningful effect on the satisfaction at a sick room and how long they will stay. 4) As the medical fee system for those sanatorium hospitals are not well prepared, long-term hospitalization gives patients financially big burden. So, it is urgent to make a complementary policy. Finally, further study should be done to set up a detailed architectural standard that stipulates that the long-term hospitals should make the environment pleasant.

저자들은 만성알콜중독의 원인으로 음주자의 성격, 사회요인 등 여러가지 문제들이 게재되어 있지만 유전적 요인도 중요하리라고 생각되어 만성알콜중독자로 진단되어 국립부곡정신병원에 입원가료 중인 환자 30명을 대상으로 ADH2의 다형현상(polymorphism)을 조사하여 알콜중독자가 아닌 건강한 한국인의 유전자형과 비교한 결과 다음과 같은 결과를 얻었다. 만성알콜중독자 30명 중 ADH2-1/ADH2-1 형을 갖는 사람이 27명이었으며 ADH2-1/ADH2-2를 갖는 사람이 3명이었다. ADH2¹의 gene frequencies는 0.68이었으며 ADH²의 gene frequencies는 0.32로서 정상 한국인과 비교하여 유의한 차이가 없었다. This study was performed to know the gene polymorphism of alcoholic dehydrogenase(ADH)-2 in 30 Korean alcohol addicted patients who were admitted at Bugok National Mental Hospital. The results were as follows ADH-2/ADH2-1 type among 30 alcohol addicts were 27 and ADH2-1/ADH2-2 type were 3. Gene frequencies of ADH2-1 were 0.68 and gene frequencies of ADH2-2 were 0.32 These results were not different from the gene polymorphism of ADH2 in non-alcoholic Korean healthy adults.

This paper discussed an optimal design of BLDC motor using rare earth magnet. Because of the characteristic that rare magnets have high remanence, in motor design using rare earth magnet, a saturation of steel has to be considered. For this, we used a nonlinear finite element method. A niching genetic algorithm is used for the optimal design of the motor. For the connection of finite element method and niching genetic algorithm, a parametric finite element system is used. As a result, we found out several BLDC motor shapes increasing a torque in the same space.

We have determined the earth loads(EL's) as a function of trench width(TW) and backfill height(BH) for the flexible pipe constructed with a narrow trench and a wide trench based on the Marston's theory. From these studies, we obtained the following results and conclusions as listed below. 1) The EL and transition width increase with increasing γ??·p for a high BH, However, the transition width is limited below 1.25 times the radius of the pipe for a low BH, and the EL increases with γ??·p only by negligibly small amounts. 2) The EL increases with the BH for a narrow range of the TW for a flexible pipe, but the rate of increase decreases about a certain value of the TW. 3) It is found that for a given TW, there exists a critical BH below which a wide trench buried condition is more effective in reducing the EL than a narrow trench buried condition. 4) There exists a minimum BH above which a narrow buried condition is preferd depending on the backfill materials. The minimum BH's are 2.5m, 1.5m, and 2.0m for the saturated clay of kμ'= 0.11, the granular materials without cohesion of kμ'= 0.19, and odinary soils of kμ' ranging from 0.13 to 0.17. It is recommended to use the prism load rater than the Marston's EL for the sake of safety consideration. 5) The values of the EL obtfive different methods for a given coefficient of earth pressure have been found to decrease in sequential order of Marston(1) 〉 Marston(2) by n(2) 〉 Wetzorke(1) 〉 Chrstensen 〉 Wetzorke(2).
