Background:Empirical use of fresh frozen plasma (FFP) in perioperative blood transfusion leads to high wastage of FFP. However, coordination of many related clinical departments is difficult. Therefore, quality improvement (QI) activities for establishment of appropriate use of FFP are needed. Methods:Departments of surgery (all surgery departments except ophthalmology) and the departments of anesthesiology, clinical pathology, and nurses met each month from March, 2011 to October, 2011. Each department investigated the number of FFP usages, wastage, and coagulation tests. Primary measured variables and objectives were decrease of 50% of FFP wastage rate compared with the previous year and 50% increase of coagulation testing before using FFP. Secondary measured variables were total amount of FFP usage and report time for coagulation tests. Results:After the QI activities (March, 2011∼October, 2011), FFP wastage decreased, from 71.5 units during the second half of 2010 to 37.8 units during the second half of 2011 (−47.1%). Rate of coagulation testing before using FFP more than doubled during the second half of 2011 (57%) compared with the second half of 2010 (25%). The rate of less than 30 minutes report time for coagulation testing increased from 60% to 75%. FFP transfusion per 1,000 surgical cases decreased to from 190 units to 118 units. Conclusion:Rate of FFP wastage and transfusion decreased and rate of performance of the blood coagulation test was enhanced through education and training on transfusion and QI activities. 배경: 수술 관련 수혈에서 신선동결혈장의 경험적 사용이 많고 폐기율 또한 높게 나타나고 있어 적절한 사용이 요구된다. 더구나 현실적으로여러 진료과가 관련되어 있어 체계적인 수혈관리가 힘든 상황이다. 이에 질 관리팀을 구성하여 신선동결혈장의 적절한 사용을 유도하였다. 방법: 외과 계열 진료과(외과, 정형외과, 산부인과, 이비인후과, 흉부외과, 신경외과, 비뇨기과, 성형외과)와 마취통증의학과, 진단검사의학과, 간호부 담당자들이 2011년 3월에서 10월까지 매달 1회의 모임을 8회 가지며 각 진료과별 신선동결혈장 사용량, 폐기량과 혈액응고검사 건수를점검하였고, 적정 사용을 위한 방안을 도출하여시행하고, 수혈지침에 대한 교육을 실시하였다. 각 과별 신선동결혈장 폐기량의 전년도 대비50% 감소와 사용 전 혈액응고검사 시행 비율50% 이상을 1차 측정 변수 및 목표로 하였다. 2차측정 변수로 각 진료과별 신선동결혈장 사용량과혈액응고검사 보고 시간도 측정하였다. 결과: 질 관리팀의 활동(2011년 3∼10월) 전후신선동결혈장 폐기량은 2010년 하반기 71.5단위에서 2011년 하반기 37.8단위로 47.1% 감소하였다. 신선동결혈장 사용 후 혈액응고검사 시행 비율은 2010년 하반기의 25%와 비교하여 2011년하반기가 57%로 두 배 이상 증가하였으며, 혈액응고검사 소요 시간은 30분 이내 보고 비율이 같은 기간 60%에서 75%로 증가하였다. 수술건수대비 신선동결혈장 사용량은 1,000건당 118단위로 전년도의 190단위에 비해 38% 감소하였다. 결론: 수술 및 수혈관련 진료과에 대한 수혈 관련 교육과 질 관리 활동을 통해 혈액응고검사의시행 비율을 높이고 신선동결혈장 폐기량과 수혈량 감소를 이룰 수 있었다.

Objects : To gain better insights of East-west integrated treatment of ischemic stroke. We analyzed 89 patients with severe acute ischemic stroke who were admitted to the East-west integrated intensive care unit. Methods : Subjects enrollment was from the East-west integrated intensive care unit of Kyung Hee Medical Center from March 2006 to February 2007. Patients were admitted within 14 days after the onset of ischemic stroke. We assessed the subjects' general characteristics, risk factors, admitting routes and periods, diagnostic imaging, process of western treatment and Korean traditional treatment, complication and consequence. Results : The proportion of males was 50.6%, of females 49.4%, average age was male 66.0$\pm$10.3 and female 71.1$\pm$10.5. Average length of hospital stays was 19.5 days. Monthly admissions were highest in November and December. The admission route was through emergency room (61.8%) or ward (34.8%). Mean Glasgow coma scale score was 10.0$\pm$2.5, average time from symptom of onset to hospital admission was 2.3$\pm$2.2 days. Dominant ischemic vascular territory was middle cerebral artery (66.3%). Initial western treatment was argatroban (22.5%), urokinase (28.1%), and heparinization (38.2%). Distribution of Sasang constitution of So-yang to Tae-eum to So-eum was equal to 5.4 to 2.9 to 1.5. Major complications were observed in 40 (42.7%) patients. In hospital mortality was 12.4% (11 deaths), all of them caused by aggravation of neurological deficit and only 3 of them with major complications. There appears to be a significant positive relationship between length of hospital stay and occurrence of complications (P<0.05). After discharge from the ICU, 64 (71.9%) patients were improved, 11 (12.4%) patients had expired, and 14 (15.8%) patients were transferred. Conclusions : From this study, we suggest that patients with severe acute ischemic stroke should be treated with East-west integrated therapy for more favorable consequences and decreased mortality.

Abdominal obesity, especially in middle-aged women, is closely associated with cardiovascular and metabolic disease. A lot of treatments including exercise and massage have been used to reduce abdominal obesity. Recently, massage with warming stone were frequently used for abdominal obesity in practice. However, there is no scientific evidence on the effect of massage with warming stone on abdominal obesity. Therefore, we investigated the effect of massage with warming stone on abdominal obesity in middle-aged women. Ten women (mean age 44.40±3.56 years, BMI 27.67±2.81 kg/m2, WHR 0.92±0.04 ratio) without any health problem were recruited. All subjects were treated by massage with warming stone for 40 min once a day, twice a week, during 8 weeks. Data including height, weight, body mass index (BMI), % body fat (%BF), obesity index (OI), waist circumference (WC), waist to hip ratio (WHR), % abdominal fat (%AF), and thickness of abdominal subcutaneous fat (TAF) were measured at before treatment (PRE), 4 weeks (4 wks), and 8 weeks (8 wks) after treatment. Also, blood content such as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were measured at PRE and 8 wks after treatment. The present results showed that most data such as weight, BMI, OI, WC1-3, WHR, %AF, and TAF were significantly decreased at 4 wks and 8 wks compared to the PRE (p<.05), while there were no statistical differences in %BF, TC, TG, HDL-C, and LDL-C between PRE and 8 wks. Related to the measurement site of WC, the biggest decrease of WC was observed in WC1 (4.7 cm) while the lowest decrease was observed in WC3 (2.74 cm). In summary, the findings of our study provide the evidence that massage with warming stone for 4 week reduced the risk of abdominal obesity in middle age woman by decreasing abdominal obese factors such as weight, BMI, OI, WC, WHR %AF, and TAF. Therefore, it can be suggested that massage with warming stone may be effective method for reducing abdominal obesity in middle age woman.

본 연구에서는 트레드밀 운동이 외상성 뇌손상 쥐의 공간학습장애와 뇌의 흑질(substantia nigra), 선조체(striatum), 그 리고 해마(hippocampus) 부위에서 tyrosine hydroxylase(TH) 발현에 미치는 효과를 규명고자 하였다. 본 연구의 실험동물 은 Sprague-Dawley 계열 7주령 수컷(210 ± 10g) 60마리를 사용하였으며, 실험실 환경에 적응시킨 후 sham-operation 그룹, sham-operation and exercise 그룹, TBI-induced 그룹, 그리고 TBI-induced and exercise 그룹으로 각 15마리씩 무작위 배정하였다. TBI 그룹은 streotaxic frame을 사용하여 외상성 뇌손상을 유발하였고, sham 그룹은 동일한 수술 스트 레스를 주었으나 외상성 뇌손상은 유발하지 않았다. Exercise 그룹은 treadmill 운동을 실시하였는데, 1일 30분, 연속 10일 동 안 2m/min 5분, 3m/min 5분, 그리고 4m/min 20분 저강도 운동을 실시하였다. 또한 실험 전·후로 공간학습능력을 측정하기 위하여 radial 8-arm maze 검사를 실시하였고, 뇌 부위별 TH 발현을 검사하기 위하여 TH 면역조직화학법을 실시하였다. 실 험결과, sham-operation 그룹과 비교하여 TBI 그룹에서 공간학습장애가 나타났고, 모든 뇌 부위에서 TH 발현이 유의하게 감 소하였다. 그러나 트레드밀 운동은 TBI로 유발된 공간학습장애를 완화시켰고, TH 발현도 모든 뇌 부위에서 증가시켰다. 이 러한 연구결과는 규칙적인 운동은 다양한 뇌부위에서 외상성 뇌손상으로 인한 TH 발현 감소를 억제시킴으로써 외상성 뇌손 상으로 인한 인지기능의 감소를 완화시킬 수 있는 가능성이 있음을 보여준다.

정규현,김형태,허홍일,Jeong, Gyu Hyeon,Kim, Hyeong Tae,Heo, Hong Il 대한화학회 1994 대한화학회지 Vol.38 No.5

Penicillin으로부터 유도된 4-mercaptoazetidin-2-one(2a)은 염기조건에서 불안정하지만 Et3N이나 pyridine 염기하에서 acetyl chloride, methyl chloroformate, ethyl iodoacetate, diethyl azodicarboxylate 등의 친전자체와 반응하여 sulfur에 acetyl, methoxycarbonyl, ethoxycarbonylmethyl, diethoxycarbonylhydrazineo원자단이 부착된 화합물이 된다. 반면 thiol의 methylation은 methyl iodide와의 반응으로 얻을 수 없고 diazomethane을 사용해야 한다. 또한 화합물 2a의 이성질체인 화합물 3a의 반응성도 화합물 2a와 거의 비슷하다. The penicillin-derived 4-mercaptoazetidin-2-one(2a) was unstable in basic media, but it reacted with electrophiles such as acetyl chloride, methyl chloroformate, ethyl iodoacetate, diethyl azodicarboxylate in the presence of triethylamine or pyridine to give the products such as S-acetyl, S-methoxycarbonyl, S-ethoxycarbonylmethyl, and S-diethoxycarbonylhydrazino compounds. However S-methylation could not be done with methyl iodide, but with diazomethane. The reactivity of isomer 3a toward electrophiles was almost the same as that of compound 2a.
