Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

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.

김상태,배진호,김상범,임승운,민병상,신영덕 대한마취과학회 2000 Korean Journal of Anesthesiology Vol.38 No.3

Background : COPA (cuffed oropharyngeal airway) is a convenient device for airway management in patients undergoing general anesthesia for elective surgery in supine position. It causes less pharyngeal trauma than LMA(Laryngeal mask airway). The purpose of this study was to compare the effect of COPA with and without muscle relaxant. Methods : Forty patients with ASA physical status I and II for elective surgery were randomly assigned to two groups. Anaesthesia was induced with propofol (2 mg/kg) and vecuronium (1.5 mg/kg) and was administered intravenously in Group I but not in Group II. Mask ventilation was done for 5 min with 0: 5 L/min. COPA was placed and heart rate, and systolic, mean, diastolic blood pressure and peak inspiratory pressure were measured at 1 min interval for 5 min. Anaesthesia was maintained with pro- pofol 150 ㎍/kg/min, fentanyl 1 ㎍/kg/hr, O_2 2 L/min and N_2O 2 L/min. Results : There were no significant differences between Group I and Group II in heart rate, systolic, mean and dstolic blood pressure. PIP (Peak inspiratory pressure) was increased and hiccups occurred significantly (p $lt; 0.05) in Group II. Complete airway obstruction occurred in one patient of Group I and severe coughing, body movements and gagging occurred during induction and insertion in Group II. conclusions : With the use of appropriate muscle relaxant, we can use COPA without increased inspiratory pressure or significant complication.

Hong, Sung-Tae,Lee, Sang Hyup,Lee, Seung-Jin,Kho, Weon-Gyu,Lee, Mejeong,Li, Shunyu,Chung, Byung-Suk,Seo, Min,Choi, Min-Ho 梨花女子大學校 藥學硏究所 2003 藥學硏究論文集 Vol.- No.12

Praziquantel is rapidly absorbed and secreted; and thus fractional doses are recommended for the treatment of cestode and trematode infections. In the present study, we developed a new praziquantel tablet formula allowing sustained-release (SRP). In vitro dissolution of SRP tablets showed that praziquantel at 300 ㎎/tablet combined with hydroxypropyl methylcellulose dissolved completely at a constant rate over 10 h, whereas the conventional praziquantel tablet (PZQ) was only 40% dissolved. Pharmacokinetic studies in dogs confirmed that SRP was absorbed more slowly than PZQ. The mean value of the area under the concentration/time curve from 0 h to the final observation time, the maximum concentration in serum, and the time of maximum concentration in serum for SRP were 3.471.500 ng/min for 0.25 ㎖, 10,300 ng for 0.25 ㎖, and 192 min. while the values for PZQ were 688,600 ng/min for 0.25㎖, 2,500 ng for 0.25㎖, and 135 min. The cure rate in dogs with a heavy infection (500 metacercariae) treated with a single dose of SRP (150 ㎎/tablet) at 50 ㎎/㎏ was 80%, while in dogs treated with a single dose of SRP (300 ㎎/tablet) at 30 mg/kg it was 60%, and the cure rate with PZQ was 20%. In each case. the egg reduction rate was similar (over 90%). No abnormal liver functions or hepatic or renal pathologies were observed in dogs administered with SRP at 30 ㎎/㎏. The SRP tablet showed sustained release and slow absorption; and it had an improved anthelmintic efficacy against Clonorchis sinensis in experimental dogs. compared with conventional praziquantel.

The microvasculature of the brain is also quite susceptible to ischemic insult, and substantial portions of the brain are not reperfused after restoration of the blood supply following overtime of critical ischemic periods. The purpose of this series of experiments was to determine the effects of ischemia on subsequential regional cerebral blood flow measurements and cortical electric activities following reperfusion after ischemia and also to define the proper time of vascular occlusion without irreversible neural damage. Cerebral ischemia was induced in cat by bilateral common carotid occlusions for periods of 10, 30, to 60 minutes, and the blood supply was reperfused for 3 hours after clamp-off. Regional cerebral blood flow(rCBF) was measured by hydrogen clearance technique following ischemia, restoration of blood supply and electroencephalogram recovery could be predicted according to the rCBF. Forty adult cats weighing 2.7 to 4.0㎏ were used in this study. The animals were divided into 4 groups of 10 cats each : normal control, 10 min-clamped, 30 min-clamped, and 60 min-clamped groups. The results obtained were as follows : 1) The mean rCBF was 24.6±7.0㎖/100g/min in control group. 2) Bilateral carotid occlusions resulted in a reduction of the rCBF(12.4±4.1㎖/100g/min) to 50% of control flow on both hemispheres. 3) Sequential changes of the rCBF after reperfusion : (1) There was restored the rCBF(21.3±5.1㎖/100g/min) to control flow in the 10 minutes-clamped group. (2) There was a 85% recovery of control flow in the 30 minutes-clamped group. (3) There was a only 25% recovery of control flow in the 60 minutes-clamped group. 4) A close correlation was found between cortical electrical activity and rCBF suggesting a threshold relationship. (1) The changes of cortical electric activity began to notice at rCBF less than 17.4±4.7㎖/100g/min. (2) The recovery of cortical electric activity noted at rCBF more than 10.2±2.3㎖/100g/min. 5) There was no evidence of ischemic involvement at the cortex, white matter and basal ganglia in the 10 minutes clamped group, but demonstrated a dense wedge shaped infarct at the cortex and uncus herniation in the 60 minutes clamped group. The rCBF and cortical electric activity restored to normal values in reperfusion within 10 minutes after occlusion of both common carotid arteries.

본 연구에서는 조제분유 중의 콜레스테롤을 신속하고 정확하게 분석하기 위해 지방 추출 과정을 거치지 않는 직접 검화 방법을 선택하여 분석법 개발을 시도하였다. 조제분유 분말시료를 직접 검화 수기에 취하여 검화 온도, 검화 시간, KOH 농도의 3가지 인자에 대해 콜레스테롤 회수율이 가장 양호하게 나타나는 최적 검화조건을 확립하고, 검화 후 수세과정에서 액액 분배가 용이한 용매 조건도 확립하였다. 또한 콜레스테롤 피크의 완전한 분리를 위한 적정 기기 조건을 확립하였다. 그 결과, 시료 약 2 g에 16 M-KOH 10 mL를 넣고 $90^{\circ}C$에서 60분 가열하여 검화한 후 diethyl ether로 3회 추출하고 hexane을 최종시험용액으로 하여 기기분석을 했을 때의 회수율이 98.80%로서 가장 양호하게 나타났다. 본 연구를 통해 개발된 조제분유의 효율적인 액액분배 및 직접가열 검화법은 일원배치 분산법에 의해 유화가공식품의 콜레스테롤 분석법으로 유효성이 검증되었으며, 아울러 개발된 전처리 방법 및 기기 분석 조건을 활용해 다양한 분석 기관에서 신속 정확하고 효율적인 콜레스테롤 분석을 수행할 수 있을 것으로 기대된다. 또한 산업체의 품질관리 및 검증기관에서 필요시 모니터링에 적극 활용 가능할 것으로 사료되며, 이를 통해 유화가공식품 류의 함량표시 및 규격관리의 정확성과 효율성 증대에 기여하여 제조업체의 정확하고도 효과적인 품질 및 안전성 확보에 기여할 수 있을 것으로 판단된다. 특히 위해 물질에 대한 정확한 함량 판단이 중요한 조제분유 등의 영 유아용 식품의 안전성 확보에 지대한 공헌을 할 수 있을 것으로 기대된다. An improved cholesterol analysis method was developed for powdered infant formula by gas chromatographic separation after liquid-liquid extraction and partition. In the official Korea Food Standard method for cholesterol analysis, the water phase and solvent phase were not well separated in the case of emulsified foods such as powdered infant formulas and baby foods. For the rapid and simple sample preparation method, an optimized direct saponification condition was established for heating temperature, heating time, and KOH concentration. From the results, the optimum conditions were as follows: heating temperature $90^{\circ}C$, heating time 60 min, and 16 M KOH 10 mL for a 2 g infant formula sample; improved separation condition for gas chromatography was as follows: the initial oven condition was $250^{\circ}C$ for 25 min, the oven temperature was increased to $290^{\circ}C$ by $10^{\circ}C$/min ratio, and finally the oven temperature remained at $290^{\circ}C$for 9 min. The developed method could be implemented for the study of cholesterol, providing the advantages of reduced inspection time and cost in emulsified foods such as infant formula.

Backgrounds: One of the main problems conditioning the outcome of islet transplantation is the ability to separate a sufficient number of viable islets with preserved function. Islet purification is critically affected by all of the isolation stages. Thus, it is necessary to set up the standard isolation method that islets are separate well from acinar without compromising islet yield and viability. Methods: Twenty three adult mongrel dogs were used for the experiment of total pancreatectomy with islet isolation. The islets were properly isolated by a modified Recordi method. The obtained islets were further purified by centrifugation on discontinuous gradients using cell separation system (Model 2991, Cobe, Lakewood Colo). We evaluated islet number (islet equivalent number, 150 um equivalents/kg of recipient body weight, IEq/kg), purity, cell volume, viabilty, recovery rate, and comparison of outcome according to the isolation conditions. Results: 1) The mean of islet numbers before purification were 13543±9431Eq/kg, digestion times were 13.8±2.6 min., digestion temperature was 37.4±0.2℃, purity was 59.7?.0%, viability was 90.0±2.1%, cell volume was 4.7±1.1 mL, islet number after purification were 4064±361 IEq/kg, and recovery rate was 29±2.9%. 2) Isolated islet numbers were different according to the degree of pancreas distension with collagenase, digestion temperature, and digestion time. 3) The best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase. 4) According to multiple regression adjusted by variable factors, the degree of pancreas distension with collagenase and digestion time were independently associated factors for successful islet isolation. Conclusions: In this study, we concluded that the degree of pancreas distension with collagenase and digestion time were independent factors for successful islet isolation and the best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase.
