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.

본 연구의 목적은 정신지체 학생의 구강건강 실태 및 치아우식 활성도를 평가하여, 학생들의 구강건강 증진을 위해 필요한 교육 방안을 모색하고, 실제적인 구강건강 관리 향상을 위한 기초 자료를 마련하고자 하는 것이었다. 광주광역시 소재 S 정신지체특수학교 유아부부터 고등부까지의 학생을 대상으로 조사를 실시하였다. 구강건강실태를 평가하기 위한 구강검사는 213명에 대해 시행하였으며, 치아우식활성도 검사는 197명에 대해 시행하였다. 치아우식활성도 평가를 시행한 197명의 정신지체 학생 중 우식활성이 고도인 학생은 33명(16.77%)으로 나타났으며, 13세 이하가 그 이상의 연령에 비해 치아우식활성도가 높았다. 치아우식활성도의 경중도와 치은염 유무와는 관련성이 없는 것으로 나타났다. 정신지체 장애학생의 치아우식활성도 경중과 치아우식경험지수와의 상관성을 평가한 결과, 치아우식활성도가 증가할수록 우식경험치율과 우식경험치지수가 높은 양상을 보였으며, 특히 유치의 경우 우식경험유치율 및 우식경험유치지수는 치아우식활성도와 높은 상관성을 보였다. The purpose of this study is to evaluate oral health status, caries-inducing bacterial activity of the mental retardation students, and developing motivation method for improving oral hygiene management by clarifying the relationship between caries- inducing bacterial activity and oral health status of mental retardation students. Caries experience indices, caries susceptibility test, gingival health evaluation, and oral hygiene management and oral health survey were performed. Results were as follows: 1. The DMFT index of disabled students(12 years) was 2.07. 2. The gingival inflammation was occurred more frequently in older ages. 3. There also was a high positive correlation between caries incidences and the results of caries-inducing bacterial activity test especially in deciduous teeth. This result suggested that the Dentocult SM mutans test as a caries activity test is a reliable method for measuring the status of dental caries in mental retardation students. Because it would motivate the mental retardation students to care more actively for their oral hygiene if they learn how much dental caries-inducing bacteria are living in their mouth by observing the bacterial colony on the cultured test strip, it can become a possibly efficient educational tool for the mental retardation students.

It has been generally accepted that cost and time are in reverse proportion. But, due to the resource constraints such as resource capacity, resource availability, resource continuity and resource level, time and cost could have unfixed relation and time-cost trade-off curves could take various forms. This study proposes the labor-related constraints affecting the time-cost trade-off problems and analyzes the effects.

In this paper, it is presented a new technique to the design and real-time implementation of fuzzy control system based-on digital signal processors in order to improve the precision and robustness for system of industrial robot. Fuzzy control has emerged as one of the most active and fruitful areas for research in the applications of fuzzy set theory, especially in the real of industrial processes. In this thesis, a self-organizing fuzzy controller for the industrial robot manipulator with a actuator located at the base is studied. A fuzzy logic composed of linguistic conditional statements is employed by defining the relations of input-output variable of the controller, In the synthesis of a FLC, one of the most difficult problems is the determination of linguistic control rules from the human operators. To overcome this difficult, SOFC is proposed for a hierarchical control structure consisting of basic level and high level that modify control rules. The proposed SOFC scheme is simple in structure, fast in computation, and suitable for implementation of real-time control. Performance of the SOFC is illustrated by simulation and experimental results for robot with eight joints.

In order to study the mechanism of the copper accumulation in the cell of copper-tolerant bacterium, Pseudomonas stutzeri, distribution of the copper in the cell were investigated. Approximately 61% of the accumulated copper was distributed on the cell wall and the other 39% portion was in cytoplasm. 78% of the copper in the cell wall fractions was present in the polyphosphate and polysaccharide fractions, but most of copper in the cytoplasm fractions was in protein and nucleic acid. Copper affected the protein synthesis in P. stutzeri. The intracellular protein content was decreased by copper addition, but the soluble protein precipitated by ammonium sulfate(30-75% saturation) was increased as compared to that from the cells grown without copper. Furthermore, in the cells grown with copper, high-molecular-weight soluble protein was increased, compared with the cells grown without copper, but low-molecular -weight soluble protein was decreased. These results indicate that copper inhibited the intracellular protein biosynthesis but enhanced the biosynthesis of the high-molecular-weight soluble protein precipitated by ammonium sulfate(30-75% saturation).

This study was carried out to determine therapeutic the effect of ozonated water therapy on bovine pododermatitis. In addition, bactericidal effect of ozonated water on etiological agent of bovine pododermatitis was examined. The pathohistological examination for the pododermatitis, according to application with ozonated water and ozone ointment was investigated. Thirty healthy cattle were divided two groups(each of 15) : control group (povidone group), treatment group (ozone solution group). Various parameters were evaluated in terms of the lameness score, swelling score, lesion score, WBC count, neutrophil count, pathohistological finding, and antimicrobial action. The decrease of lameness and lesion score were shown in hoof lesions on 14 days after application of ozonated water. Significant decrease of swelling was shown in hoof lesions on 14 days 1 Corresponding author after application of ozonated water(p < 0.01). In hematological findings, WBC count revealed values within normal range. The number of neutrophils was slightly higher than that of normal, however, this was improved on 14 days after application of ozonated water. In pathohistological findings, recovery was rapid macroscopically and microscopically in the treatment with ozonated water on the hoof lesions and ozonated water was effective. In antimicobial action, bactericidal effect was observed in treatment with ozonated water on the hoof lesions and ozonated water was effective.

Di-(2-ethyl hexyl) phthalate(DEHP)가 rat의 혈액상 및 약물대사효에 미치는 영향

임수한,홍사욱 成均館大學校 科學技術硏究所 1990 論文集 Vol.41 No.1

Di-(2-ethylhexyl) phthalate(DEHP), one of plasticizers in plastic has recently been reported as a potential hepatotoxic agent. Liver enlargement associated with a decrease in the activity of mitochondrial enzyme and modification in biological response of xenobiotics after oral or intraperitoneal administration of DEHP has been observed in rodents. However, their subtle toxic effects have not been fully investiqated and thus more detailed studies are required. In this paper, we examined the toxic effect of DEHP on the liver and kidney function and biochemical parameters in rats. The biochemical parameters such as AST, ALT, ALP, LDH, BUN, albumin and total protein in serum were gradually increased by DEHP treatment. And more increasing tendency was observed by concomitant ethanol treatment. The contents of cytochrome P-450 and activity of NADPH-cytochrome c reductase in hepatic microsomal fraction were increased in initial period and then decreased, but those in renal microsomal fraction were little increased. However, toxic responses of DEHP in hepatic and renal cytochrome P-450 content and the activity of NADPH-cytochrome c reductase were a little suppressed by the administration of ethanol. The activity of Glucose-6-phosphatase in hepatic homogenate was decreased and MDA value in the serum and microsomal fraction of liver and kidney was significantly increased by the administration of DEHP but those of above biochemical function were keeping slowly by ethanol concomitant treatment.
