Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

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 establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L^-1 and 0.1 mg NAA L^-1. Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.

Effect of Photoperiod, Temperature and True-leaf Stage in Bolting Rate of Chicory (Cichorium intybus L. var. sativus)

Lim,Jung-Dae,Seo,Jeong-Sik,Lee,Hyeon-Yong,Kim,Jong-Dai,Lee,Jin-Ha,Yu,Chang-Yeon 한국자원식물학회 2004 Plant Resources Vol.7 No.1

Root chicory (Cichorium intybus L. var. sativus) is potential alternative medicinal and sugar crop which accumulates a high amount of linear polyfructan, inulin in its roots. A problem in root production is that over-wintered stock plants often flower. Once the plant becomes reproductive, stem elongation and root growth slows and floral buds arise from every node, rendering the plants useless for propagation. The objectives of this research was to examine the effectiveness of manipulating environmental factors containing photoperiod, temperature and number of leaf states. The experiment was performed in growth chamber to create two photoperiods (8 h, and 16 h) with three temperature regimes (5℃/3℃, 10℃/8℃, and 15℃/13℃ day/night temperature) for a total of six treatments on three type of true-leaf stage of plant. Data of bolting rate, shoot and root length, shoot and fresh weight was invetigated in each treatments. This is the first report on changes in bolting rate and shoots and roots production during a whole growing season and differences in the effect of cold and photoperiod treatment depending on the true-leaf stage of plant.

전환장애와 감별해야할 Meige 증후군 1예

임세원,김진세,정인과,박민규,이대희 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.3

Meige 증후군은 안검경련과 구-하악부의 근긴장이상을 특징적으로 보이는 신경학적 임상증후군이다. 발병원인은 아직 불분명하나 아세틸콜린과 도파민의 신경활성과다(excess neuronal activity)가 원인으로 여겨지고 있으며, 치료로는 향도파민성약물과 항콜린성약물, 그리고 보튤리듐독소 주사가 이용되고 있다. 그러나 증상양상이 다양하며 심리적 영향을 받으므로 전환장애 혹은 불안장애 등의 정신과적 문제로 오진되는 경우가 있다. 저자들은 49세 여자로 초기에 전환장애로 진단되었으나 Meige 증후군임이 밝혀져 성공적으로 치료되었던 환자 1례를 경험하여 문헌고찰과 함께 보고한다. A Meige's syndrome is a rare neurological syndrome characterized by blepharospam and oro-mandibular dystonia. Its pathophysiology is not clearly determined yet, but the hypothesis of dopaminergic and cholinergic hyperactivity is most widely accepted. Anticholinergic drugs, antidopaminergic drugs and botulism toxin injection are currently used for the treatment of Meige's syndrome. The Meige's syndrome could be misdiagnosed as a psychiatric disorder such as conversion disorder or anxiety disorder, because clinical features of the Meige's syndrome are very variable and affected by psychological factors. The authors experienced one case of a 49-year-old female patient who was initially misdiagnosed as conversion disorder but confirmed later as Meige's syndrome, and then successfully treated.

Diesel engines which emit a lot of PM and NOx have been known as a main air polluter. Especially, diesel particulate matters (DPM) including black smoke are hazardous air pollutants to human health and environment. The nations retaining advanced engine technologies have reinforced emission regulations. To meet these regulations diesel engine manufacturers have developed low-emission diesel engines, aftertreatment equipments, alternative fuel technologies and so on. In this study, particle number concentrations characteristics according to particle size and engine driving conditions were analyzed when these low-emission technologies were applied. There was a tendency of increasing particle number concentrations from heavy-duty diesel engines with increasing engine rpm and load rate. In the cases of CDPF (Catalytic Diesel Particulate Filter), CNG (Compressed Natural Gas) engine and ULSD (Ultra Low Sulfur Diesel) more than 99% of particle number concentration were removed.

林恒鎭,金正洙,朴晶來 公州大學校 스포츠科學硏究所 1991 스포츠科學硏究所論文集 Vol.- No.4-5

This study is meant to calculate the change of circulational ability (Heart rate, Blood pressure) and blood components (RBC, WBC, Hb, Hct, Glucose, Total cholesterol, Total protein) at rest (30 minute of rest before exercise), after exercise and at recovery (30 minutes of rest after exercise) by using bicycle ergometer. The boys (5 athletes group, 5 non-athletes group) were chosen form "K" middle school in "K" city and were examined to raise the expectations about exercise. The method of exercise load was decided with a pre-test at 80% of maximum heart rate with bicycle ergometer (Monark : Sweden). 2 minutes of warming up at 50 in 0 kp was done, and soon without rest, main exercise was done for 5 minutes at 50 in 30 kp. Blood circulational ability and blood components were examined three times respectively at rest, after exercise and at recovery. Blood circulational test was taken at sitting position using finger for heart rate and a Sphygmemanometer (Tycos type, Auto) 5cc of blood was collected using one time injector through the antecubital vein and soon 1cc of blood (anticoagulated, EDTA-2k) was examined for blood components change with Auto Cell Counter (ABX : France). The rest of the blood was placed in a plane tube. Later a biochemistrical test was took with Hand Chemistry Analyzer (Gylford : U.S.A) and Auto chemistry Analyzer (Gylford : U.S.A). Experimental items were physique examination (Height, Weight, Chest), circulational ability test (Heart rate , Blood Pressure), hematological test(RBC, WBC, Hb, Hct) and biochemistrical test (Glucose, Total cholesterol, Total protein). The results were compared and analyzed according to experimental items, Standard deviation and mean were made by SAS package program at rest Exercise, and at recovery, The T-test about the difference in average between athletes and non-athletes was made at level of α=0.05, α=0.01 The results are as follows. 1. At rest , the heart rate of the athletes and non-athletes did not have statistical differences, but after exercise, both groups showed rapid increase with concerning difference (p<0.01). 2. At rest, the maximum blood pressure (at systolic) was lower for the athletes group with no statistical significance for both of the groups. After exercise, both groups showed high increase, and at recovery both groups showed quick recover rate. There were no concerning difference both at after exercise and at recovery. 3. At rest the blood components showed less RBC's and WBC's than the normal adults and an average rate of Hb's and Hct's. Only WBC's and Hb's showed statistical difference (p<0.05, p<0.01). 4. After exercise, both groups showed low increase of RBC's Hb's, and Hct's but WBC's showed high increase WBC's Hb's and Hct's showed concerning increase (p<0.05) 5. At recovery, both groups showed approximately 95% recovery rate of RBC's Hb's and Hct's of the blood components, but WBC's showed a high recovery rate of 106%. Only WBC's and Hb's showed statistical difference (p<0.05) 6. At rest, Glucose and Total cholesterol was lower in athletes group but there were no statistical difference in both groups. After exercise both groups showed low increase in them. Glucose showed concerning difference (p<0.01) At recovery, both groups showed rapid recovery rare, but no concerning difference. 7. At rest, Total protein was low in athletes group with no statistical significance. After exercise, both groups showed low increase with no concerning differences. At recovery, both groups recovered quickly, but were no concerning differences. Concluding the above, compared to the non-athletes group, the athlete group showed low numeric value in blood circulating ability and change in blood components at rest, after exercise and of recovery. The low numeric value in blood circulating ability and quick recovery seems to reason form everyday planed and regular exercise in which physical and biochemical changes occur which gives the ability to adjust to the moving parts. The future subject is to understand the effect to the students of early growth which happen by the influence of developing society and to do continuous research of age, sex distinction, and areas to judge the details and intensity of physical strength training, and need to research with long and planned physical strength examination.
