화학물질 누출에 의한 대량재해 : Methyl Isocyanate 누출을 중심으로

양혁준,최중명 대한응급의학회 2000 대한응급의학회지 Vol.11 No.2

Background: We are in the edge of some human made disasters such as hazardous materials and air pollution, for example, the world news reported that the city of Bhopal, India had serious victims related with a leaking out of the chemical materials, Methl Isocyanate and many people in India were killed by. These situations many people who live in this world are worrying about are not others, but just ours and people consider about that kind of the disasters are the possible situation to happen to all the people. Therefore, we performed this basic study to recognize the risk of Methyl Isocyanate leak accident and to prepare local disaster plan with EMS system. Method: Trace 8.0, a simulation software made by the U.S. company Safer System was used as a tool to estimate the diffusion distance, area and its victims at the concentrations of 0.02 ppm, 0.2 ppm, 5 ppm respectively for an assumed B-city of 2 hundred thousands population count in which was presumed 500 kg Methyl Isocyanate gas to leak out. Results: 1. During 1 hour, maximum diffusion distances of 0.02 ppm, 0.2 ppm, and 5 ppm were 5.41 km, 1.61 km and 0.29 km respectively on the plume impact. 2. Maximum population counts influenced by Methyl Isocyanate gas at the concentrations of 0.02 ppm, 0.2 ppm, and 5 ppm were 40,838, 4,346 and 222 on the plume impact, while those were 138,238, 17,261, and 1,588 on the vulnerability impact, respectively. 3. Therefore, 17,261 persons must put on respiratory device and 138,283 persons must be evacuated to safety place within 1 hour. Conclusions: Only small amount leak of Methyl Isocyanate may cause tremendous chemical disaster in urban area, so its disaster plan must be prepared with an accident simulation program and Material Safety Data Sheets (MSDS). Especially, nearby emergency center of an industrial complex must have a strong position about preparation of chemical disaster plan and perform a disaster drill of hazardous material accident annually.

朴正煥,尹太永,崔重明,朴淳永,柳東俊 慶熙大學校 1992 論文集 Vol.21 No.-

In order to study body composition by Dual energy X-ray absorptiometry, the authors selected randomly 31 adult women as subjects, who were from 21 to 25 years old and had complete growth and development, and measured their physiques(body height, body weight, chest girth and sitting height) and skinfold thickness from September 1, 1991 to March 31, 1992. On the basis of these measurements, the author calculated physical indices and total fat percent. On the basis of the results fo bone densitometry, the authors analyzed body fat weight, body composition between left and right sides, body composition according to body position, bone mineral content, bone mineral density and total bone calcium, and compared the difference between the fattiness which was calculated indirectly and that gained from the bone densitometry. After that, the authors analyzed correlation of results from two methods.

박정욱,최영규,김동욱,김건식,강화자,신옥영,신광일,최중명 대한정맥마취학회 1999 정맥마취 Vol.3 No.3

서론: 신경외과 환자중 두부고정핀을 거치하는 환자에서 경구용 clonidine 3 ㎍/㎏을 전투약한 경우 두부고정핀 거치에 의한 혈압 및 심박수에 미치는 영향을 알아보고자 본 연구를 시행하였다. 방법: 미국마취과학회 환자분류 1, 2급에 해당하는 제충 50∼70 ㎏, 20∼62세의 전신마취를 필요로 하는 두개강내 수술환자중 두부고정핀을 거치하는 40명으로 술전 혈압이 정상이고 순환계, 호흡계 및 자율신경계 질환의 기왕력이 없는 환자를 대상으로 하였다. 대상환자는 두군으로 나누어 대조군(n=20, 제1군), clonidine군(n=20, 제2군)으로 무작위로 나누었으며, 전투약으로는 대조군에서는 glycopyrrolate 0.2 ㎎을 수술실 입실 한시간 전에 근주하였으며, clonidine군에서는 clonidine 3 ㎍/㎏을 수술실 입실 90분전에 경구투여하고 glycopyrrolate 0.2 ㎎은 수술실 입실 한시간 전에 근주하였다. 본 연구에서 측정하고자 하는 혈압 및 심박수는 제1군 및 제2군 모두에서 두부고정핀에 의한 고정이 시작되기 전에 측정한 측정치를 대조치(C)로 하고 고정핀을 고치한 직후부터 1분 간격으로 10분(T1∼T10)까지 10회에 걸쳐 수축기혈압, 이완기혈압, 평균동맥압 및 심박수를 관찰하여 대조치와 비교한 후 대조치에 따른 백분율로 증감을 보았다. 또한 제1군과 제2군을 비교하여 clonidine 투여의 효과도 비교하였다. 결과: Clonidine 3 ㎍/㎏의 투여군과 대조군을 비교시 수축기혈압은 두부고정핀 거치후 3분(P<0.05), 6분(P<0.05), 7분(P<0.05), 9분(P<0.05), 10분(P<0.01)에, 이완기혈압은 1분, 3분(P<0.05), 7분(P<0.05), 9분(P<0.01), 10분(P<0.05)에, 심박수는 1분(P<0.05), 7분(P<0.01)에 의미있는 차이를 볼 수 있었다. 결론: Clonidine 3 ㎍/㎏의 전투약은 두부고정핀의 거치에 의해 발생되는 혈압의 상승 및 심박수의 증가를 의미 있게 감소시키는 효과를 발견할 수 있었다. Backgroud: The aim of this study was to observe the effect of premedication with oral clonidine on hemodynamic changes in patients undergoing pin head-holder application for neurosurgical operation. Methods: Sixty ASA Ⅰ/Ⅱ patients in a double-blind prospective study were assigned randomly to receive placebo (Group 1, m=20) or clonidine (Group 2, 3 ㎍/㎏/po, m-20) 90 minutes before surgery. Blood pressure (BP) and heart rate (HR) were monitored continuously during and immediately after anesthetic induction. Anesthetic induction was achieved with vecuronium (0.1 ㎎/㎏), thiopental sodium (5 ㎎/㎏) and N_2O+O_2+isoflurane, maintained with N_2O+O_2+isoflurane. Hemodynamic response such as systolic BP, diastolic BP, mean arterial pressure and HR to pin head-holder application was checked just before application (control value), 1 to 10 min after application with or without clonidine administration and compared between groups. Results: In clonidine treated group (Group 2), at 3 min (P<0.05), 6 min (P<0.05), 7 min (P<0.05), 9 min (P<0.05), 10 min (P<0.01) in systolic BP, at 1 min (P<0.01), 3 min (P<0.05), 7 min (P<0.05), 9 min (P<0.01), 10 min (P<0.05) in diastolic BP, and at 1 min (P<0.05), 7 min (P<0.01) in HR after pin head-holder application were significantly lower than control group (Group 1). Conclusions: We conclude that preoperative oral treatmetn with clonidine 3 ㎍/㎏ reduced hemodynamic changes effectively after pin head-holder application.

제주도 주민에서 Human T-cell Lymphotropic Virus Type Ⅰ(HTLV-Ⅰ) 감염에 관한 혈청역학적 연구

강석민,박순영,최중명,김원천,최창현,윤태영,김응,김준명,유동준 대한감염학회 1997 감염 Vol.29 No.3

목적 : Human T-cell lymphotropic virus typeⅠ(HTLV-Ⅰ)은 human retrovirus로서 성인 T세포 백혈병/림프종(adult T-cell leukemia/lymphoma; ATL)과 HTLV-Ⅰ associated myelopathy/tropical spastic paraparesis(HAM/TSP)의 병인과 관련이 있는 것으로 알려져 있다. HTML-Ⅰ감염은 일본의 남서부지방에 토착화되어 있으며, 카리브해 연안, 중남미, 아프리카 일부지역이 토착지역으로 알려져 있다. 특히 최근에는 일본과 지리적으로 가까운 대만과 중국에서도 HTLV-Ⅰ 유행지역이 있음이 알려졌다. 국내에서도 1993년 여러지역의 공혈자를 대상으로 한 조사에서 항체양성률이 0.13%이었으며, 내륙보다는 일본에 가까운 지역으로 갈수록 증가하여 제주도의 경우 0.80%라는 예상외로 높은 항체양성률을 보고하였다. 따라서 제주도 주민의 정확한 HTLV-Ⅰ 항체보유율을 파악하고, 나아가서 이 지역의 HTLV-Ⅰ감염의 전파경로를 규명하여 향후 HTLV-Ⅰ 감염예방 및 관리를 위한 대책을 마련코자 광범위한 혈청학적 및 역학적 조사를 실시하였다. 방법: 1995년 12월부터 1996년 3월까지 제주도 주민 2,372명으로부터 혈청을 채취하여 microtiter particle agglutination test를 이용하여 HTLV-Ⅰ 항체양성여부를 판정하였다. 혈청검사에서 양성을 보인 조사대상은 상담조사를 통해 수혈여부, 정맥주사용 마약사용여부, 일본인과의 성접촉여부, 일본에서의 출생 및 생활여부, 현재 및 과거질환력, 부모, 자식, 배우자의 질환력 등에 관하여 알아보았다. 결과: 제주도 주민 2,372명 중 항체양성자는 19명으로서 항체양성률은 0.80%이었다. 남자에서의 항체양성률은 0.78%이었으며, 여자에서의 항체양성률은 0.82%로서 여자에서 남자보다 항체양성률이 높았다. 항체양성률은 20대에서 1.45%로 가장 높았으며, 다음이 40대 1.41%, 10대 이전 0.91%, 30대 0.70%, 50대 0.54%의 순으로 나타났다. 항체양성자의 평균연령은 35.5세이었으며, 남자의 경우 35.2세, 여자의 경우 35.7세이었다. 지역에 따른 항체양성률은 제주시, 북제주군이 각각 0.61%인데 반하여 일본에 면해 있는 남제주군, 서귀포시는 각각 0.83%, 1.37%로서 더 높았다. 항체양성자에 있어서 감염위험인자 및 관련질환유무를 조사하였으며 특별한 관련사항은 발견할 수 없었다. 결론: 본 연구에서 나타난 제주도 주민에서의 높은 항체양성률은 향후 Western blot, RIPA 또는 PCR과의 비교검사를 통해 확인이 필요하겠으며, 이들 검사에서도 높은 항체양성률이 증명된다면 수혈을 통한 높은 전염률을 고려할 때 제주도 지역만이라도 공혈자의 혈액에 대한 검색검사로서 HTLV-Ⅰ항체검사 실시의 필요성을 검토해야 할 것으로 사료된다. Background : Human T-cell lymphotropic virus typeⅠ(HTLV-Ⅰ) is a retrovirus that has been identified as a cause of adult T-cell leukemia/lymphoma and tropical spastic paraparesis. HTLV-Ⅰ infection is highly economic in the southwestern islands of Japan, Caribbean basin, South America, and Africa. In 1993, we showed that the seroprevalence of antibodies to HTLV-Ⅰ was 0.13% among blood donors in Korea, but surprisingly, 0.80% in Cheju-Do adjacent to endemic areas of Japan. So this study was designed to reevaluate the seroprevalence of antibodies to HTLV-Ⅰ among residents in Cheju-Do. Methods : Total 2,372 residents in Cheju-Do were tested from December, 1995 to March, 1996. Anti-HTLV-Ⅰ antibodies were tested from December, 1995 to March, 1996. Anti-HTLV-Ⅰ antibodies were detected by the microtiter particle agglutination test. Result : Among total 2,372 residents, 19 were anti-HTLV-Ⅰ positive. So the overall positive rate of anti-HTLV-Ⅰ antibodies was 0.80%. The positive rate in females was higher than in males(0.82% vs 0.78%). The positive rate was 1.45% in the age group of 20-29 years, 1.41% in 40-49 years, 0.91% in 0-9 years, 0.70% in 30-39 years, and 0.54% in 50-59 years. The mean age of seropositives is 35.2 in males and 35.4 in females, with a mean of 35.3. Geographically, high positive rate was observed in Sogwipo-City(1.37%) and Namcheju-Gun(0.83%) compared to those of Pukcheju-Gun(0.64%) and Cheju-City(0.61%), which showed high seroprevalence in districts adjacent to endemic areas of Japan. Any specific risk factors or associated disorders of HTLV-Ⅰ infection could not be found among the seropositives. Conclusion : The seroprevalence of antibodies to HTLV-Ⅰ in Cheju-Do was noted to be very high by the microtiter particle agglutination test. So henceforth serosurvey by confirmative laboratory tests in needed, and if high seroprevalence is showed from it, screening of blood donors for HTLV-Ⅰ in Cheju-Do should be considered to prevent transfusion-associated HTLV-Ⅰ infection.
