관동맥연축의 비침습적 진단에 있어 Ergonovine Echocardiogrpahy의 유용성

송재관,박성욱,김재중,두영철,김원호,박승정,이종구 울산대학교 의과대학 1992 울산의대학술지 Vol.1 No.1

관동맥연축의 비침습적인 진단방법의 확립은 침습적인 관동맥조영술 및 연축유발검사에 비해 반복적용이 가능한 이론적인 장점이 있어 선별검사(screening test)로서의 기능뿐만 아니라 치료로 이용되는 약물의 효과비교 및 추적검사를 통한 관동맥연축의 임상ㄹ활동도 평가등에 손쉽게 이용될 수 있으라라 예상된다. 이에 저자들은 ergonovine 투여시 기록된 좌심실벽운동장애 유무가 갖는 관동맥연축에 의한 심근허혈의 진단적 가치를 평가하기 위해 Beside Ergonovine Echocardiography Test를 시행하였다. 관동맥조영술 및 연축유발검사에서 변이형협심증으로 증명된 30명(남자 27명, 평균연령 54세)과 비특이적인 흉통질환군 20명(여자 12명, 평균연령 55세)을 대상으로 관동맥조영술 다음날 ergonovine test를 시행하였다. 운동부하검사가 음성인 환자들을 대상으로 6시간 공복시킨 뒤 앙와위에서 상지정맥을 통하여 25-50microgram(이하 mcg)을 5뷴 간격으로 투여하여 흉통의 유무, 심전도 및 이면성심초음파를 5분마다 기록하였으며 총투여량이 350mcg에 도달하거나 양성반응을 보이는 경우 nitroglycerin 250mcg 정주 및 설하투여로 종료하였다. 좌심실벽운동의 분석은 side-by-side continuous cine-loop display가 가능한 QUAD screen 방법으로 판별하였다. 가역적인 심전도 변화나 국소적인 심실벽운동장애가 유발되는 경우를 양성으로 판정하였다. Ergonovine Echocardiography의 전체 민감도는 90%, 특이도는 100%로 동시에 기록된 심전도 변화의 민감도(73%)보다 높았으며 특히 흉통이 있으나 심전도 변화가 전혀 없었던 5례 모두에서 좌심실벽운동장애가 관찰되어 본 검사법의 우월성을 확인할 수 있었다. 양성반응을 보인 ergonovine 평균 투여량이 173±95mcg 이었으며 흉통발작의 빈도를 기준으로한 임상활동도가 높은 경우 활동도가 낮은 군에 비해 양성반응을 의한 총 ergonovine 투여량이 적었으며(123±86 vs 213±83mcg, p<0.01) 관동맥협착이 연축에 동반되어 있는 경우 정상 관동맥에 연축이 있는 경우보다 민감도가 더 높았다(100% va 60%, P=0.02). Ergonovine 투여로 혈압은 기저치 보다 약 17%정도 증가되었으나 맥박수는 큰 변화를 나타내지 않아 안전하게 시행될수 있었으며 오심, 두통, 견갑부통증, 심실기외수축, 방실차단 등이 소수례에서 관찰되었으나 검사로 인한 사망례는 없었다. Ergonovine 주입후 기록된 좌심실벽운동동장애는 심전도 변화보다 더 민감하게 관동맥연축에 의한 심근허혈을 진단할 수 있었으며 Ergonovine Echocardiography는 운동부하검사 등으로 심한 관동맥협착이 배제된 선별된 흉통환자들에서 관동맥연축의 진단에 안전하게 시행될 수 있는 민감하고 특이도가 높은 검사방법이며 변이형협심증의 임상활동도와 관동맥협착의 동반유무가 본 검사법의 결과에 영향을 미칠 수 있으리라 사료된다. The purpose of this study was to evaluate the clinical feasibility of bedside intravenous ergonovine test with echocardiography as a noninvasive diagnostic method for coronary vasospasm. Bedside ergonovine test was performed in 50 patients with chest pain one day after coronary angiography with spasm provocation test;30 patients showed positive results of provocation test while in 20 patients there was no evidence of coronary vasospasm. A bolus of ergonovine maleate(.025 or .05mg) was injected at 5 min intervals up to total cumulative dosage of 0.35mg, and 12-leads ECG and 2-D Echo were recorded every 3min after each injection. Left ventricular wall motion was analyzed with a commercially available ' QUAD' system. The positive criteria of beside ergonovine test included reversible ST segment elevation or depression, T wave changes in ECG(ECG criteria) and reversible regional wall motion abnormalities(RWMA) in Echo(Echo criteria). The overall sensitivity and specificity of ECG criteria were 73%(22/30) and 100% respectively ; The sensitivity of Echo criteria increased up to 90%(27/30) without the change of the specificity. Among 22 patients with reversible ECG changes only 73%(16/22) showed typical ST segment elevation while ST depression was recorded in 2 patients(9%) and minor T wave peaking or flattening without ST segment displacement in 4 patients(18%). Concomitant fixed coronary lesion does increase the sensitivity of the test compared to pure coronary vasospasm with ECG criteria(100% vs 60%, p<0.05). Mean does of ergonovine with positive results was 173±95 microgram(mcg) and the amount of does of ergonovine for positive result was significantly larger in patients with low disease activity (chest pain <5times/자) than those with high disease activity(213±83 vs 123±86mcg, p<0.01). There was no procedure related mortality or fatal arrhythmias. Ergonovine echocardiography is a highly sensitive and specific test for coronary vasospasm and is safe in selected patients in whom the exercise test is negative and severe fixed coronary artery disease has been excluded. Presence of concomitant fixed coronary artery disease and the degree of clinical activity of coronary vasospasm may influence the results of this test.

This study was conducted for developing the emission factors of nitrogen oxide(NOx) and carbon monoxide (CO) from the combustion boilers burning liquefied natural gas (LNG). These emission factors were compared with those of U.S. EPA and European Environment Agency (EEA). NOx and CO concentration in the flow gas were measured using Kane-May, KM9106 and Thermo Environmental Instruments Inc., 42C-HL. Measurement were conducted at thirty industrial and commercial LNG boilers. Emission factors were calculated on the basis of fuel consumption (kg-pollutant/㎥-fuel burned). NOx concentration at industrial boiler was 14~125 ppm and it was measured as 35~125 ppm at commercial boiler. NOx emission factors of industrial boiler and commercial boiler were 1.84kg/㎥ and 2.09kg/㎥, respectively. NOx emission factor of commercial boiler was higher than that of industrial boiler. The NOx emission factors estimated in this study were lower than those of U.S. EPA and higher than those of EEA. Average CO emission factor of industrial boiler was 0.65 kg/㎥ and at commercial boiler it was 0.70kg/㎥, CO emission factor at industrial boiler was lower than that at commercial boiler.

The Korean hemorrhagic fever (KHF) is an acute febrile disease with characteristic of fever, bleeding tendency, and renal failure. There are many complications of Korean hemorrhagic fever such as infection, anemia, internal bleeding, hypopituitarism, respiratory, and neurologic complication. A few cases were reported on acute pancreatitis with hemorrhagic fever abroad, but there was no case about Korean hemorrhagic fever with acute pancreatitis in this country. We experienced a case of Korean hemorrhagic fever associated with suspected acute pancreatits. With review of articles, we report a case of 51 year-old woman with KHF, where acute pancreatitis developed during management, (Korean J Infect Dis 33:376∼379, 2001)

김도관,송영식 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.2

The pathogenesis of intrahepatic cholelithiasis has an unknown etiology. The causes of gallstone formation have been suggested bile stasis due to ductal stricture, and bacterial infection and paracitic infestation of bile. The incidence of the intrahepatic cholelithiasis is higher in eastern asian country including Korea than in western countries. Variable surgical treatment modalities have been developed in past several decades. However, the treatment of intrahepatic cholelithiasis has a lot of complicated problems, because of complex intrahepatic ductal anatomy and ductal stricture. The purpose of this study is to analyse the treatment modality of intrahepatic cholelithiasis. 46 cases of intrahepatic cholehthiasis have been analysed, who had been treated with surgery or surgery and postoperative therapeutic choledochoscopy from January 1991 for 5 years at the department of general surgery and the department of medicine, Soonchunhyang university hospital . They admitted under radiological and ultrasonographic imaging diagnosis and have been followed up for 1 to 5 years. The results were as follows; 1. Sex ratio(male : female) was 1 : 1.2 and average age was 54 years. 2. The most common symptom was upper abdominal pain(84.8%), and the most common abnormal laboratory finding was elevated alkaline phosphatase(54.3%). 3. Intrahepatic stones were 28 cases(60.9%) in the left hepatic duct, 3 cases(6.5%) in the right hepatic duct, and 15 cases(32.6%) in the both hepatic duct. 25 cases of intrahepatic duct stones accompanied extrahepatic biliary stones. 4. Among 16 cases(34.8%) of intrahepatic ductal stenosis, follow-up study showed that 12 cases(85%) were graded as good. Among 30 cases(65.2%) without intrahepatic stenosis, 29 cases(95.8%) were graded as good.

Objective : The aim of this study was to review systemically clinical trials on the effectiveness and safety of herbal medicines in the treatment of osteoarthritis. Methods : Computerized literature searches were carried out on seven electronic databases, and hand-searching on some chinese medical journals in library of Kyung Hee Medical Center. Trial data were extracted in a standardized, predefined manner and assessed independently. Results : 1. Thirty reports of clinical trials and two reports of meta-analyses concerning herbal medicine were collected and reviewed Among these reports three medical herbs were applied as topical medicine and others as internal medicine. 2. The western studies established NSAIDs or placebo as their control group. Five chinese reports established formulated herb pill(Ruanshnagshenjin pill) as their control group and Six did not establish a control group at all. 3. ACR was the most highly used diagnostic criteria in the western studies while the Chinese used their official criteria established by their government or the criteria of their text books. 4. 20 reports chose the Lequesne functional index, SHAQ, WOMAC OA index, AIMS, and their own unique scoring system as the criteria of analysing the effect. Others chose clinical symptoms, articular functions, and lab finding as their criteria. 5. 7 single herbs and 19 formulated herbs were studied. Among the formulated herbs, Achyranthes japonica was studied in 10 of the studies and Angelica gigantis Radix in 8, making them the most often studied herbs among the studies.
