본 실험은 한국, 중국 및 일본 재래종 콩 유전자 자원의 주요형질 변이를 조사하고 이들 자원간의 지리적 유연관계를 비교하고자 수행하였으며, 그 결과를 요약하면 다음과 같다. 1. 경장은 한국(66㎝)이나 일본자원(54.9㎝)보다 중국자원(71㎝)에서 더 컸으며, 또한 변이도 중국자원에서 가장 큰 것으로 나타났다. 2. 개화일수 및 생육일수는 한국자원(65.5일, 151.4일)이 가장 길었으며 중국(57일, 120일)과 일본자원(59.9일, 122.4일)은 같은 경향을 나타냈다. 또한 한국과 중국자원은 지역에 따른 차이를 나타냈으나 일본자원에서는 확인할 수 없었다. 3. 백립중은 한국(18.8g), 일본(17.2g) 및 중국(14.7g) 순으로 무거웠다. 특히 한국자원은 9~11g과 23~25g에서 정점을 나타냈고, 변이폭도 가장 컸다. 반면 일본과 중국자원은 13~17g사이에서 정점을 나타냈다. 4. 협수는 중국(46.9개)이나 일본자원(36.5개)보다 한국자원(75.5개)에서 가장 많았으며, 변이폭도 한국자원에서 가장 컸다. 내도복성은 일본자원에서 가장 강하였다. 5. 정준판별분석결과 can 1을 경계로 하여 오른쪽 상하에 한국재래종이 주로 분포하였고 왼쪽에는 중국과 일본 재래종이 주로 분포하여 각 나라별로 고유한 영역을 가지고 분리되었다. 전체적 경향이 중국과 일본자원이 한국자원보다 가까운 경향을 나타냈다. This experiment was carried out to compare the characters of 944 Korean soybean landraces, 716 Chinese, and 170 Japanese soybean landraces introduced from USDA soybean germplasm collection. Cannonical discriminant and cluster analyses were conducted by their origins. The population from China was taller in plant height than those from Korea and Japan, also its variation was largest in Chinese population. The population from Korea was langer than those from China and Japan in terms of days to flowering and maturity. Also, Korean and Chinese accessions appeared the difference of those traits according to latitude. One hundred seeds weight was in the order of Korean(18.8g), Japanese(17.2g) and Chinese populations(14.7g), especially Korean population was distinguished into two groups; the group including accessions between 10 and 15g, and the other group including accessions between 20 and 25g. However, others showed the peak in range of 13~17g. The number of pod per plant was more in Korean accession(75.5) with the largest variation than Chinese(46.9) and Japanese accession(36.5). The distribution of Korean, Chinese and Japanese accessions reflected the origin of accessions analyzed by cannonical discriminant analysis. The relationship between their geographical origins showed the population of China and Japan are losely related.

Lymphangiomas are divided into three categories; (1) simple (capillary) lymphangioma, (2) cavernous lymphangioma, and (3) cystic hygroma. This lesion usually occurs in the posterior triangle of the neck but can be present in the axilla, mediastinum, or groin. Recently, we have experienced two cases of cavernous lymphangioma that one occurred in the mediastinum and the other was in the right chest wall, which were surgically removed successfully and confirmed histopathologically.

곽동진,정윤석,진재우,조준필,김 철,김행재,배택환,김준식 대한응급의학회 1995 대한응급의학회지 Vol.6 No.1

Natural or man-made disasters are serious enough to paralyse the functions of the nation or regional distinct and affect the property and lives of numerous citizens. The first two hours after occurrence of the disaster are critical for determining death or permanent disabilities of the casualties. The current Disaster Medical Service(DMS) System in our country adopts mainly civil defense model which focuses the cause of the accident, compensation of the victims, or reconstruction. So in the initial phase of disaster, the appropriate rescue and emergency treatment is not provided effectively. In order to assess and reorganize the current status of DMS System in Korea, the Department of Emergency Medicine, Ajou University School of Medicine, planned and conducted an emergency response exercise in Suwon city on April 28, 1995. The exercise, which took place near the Kyunggido Culture and Art Center, coordinated the efforts of the Suwon Fire Department and other related agencies. As well as providing training on emergency response, the exercise was valuable for identifying areas of weakness which will be address in the future.

Blunt or nonpenetrating chest injuries are common after motor vehicle accidents or falls. Blunt injury to the heart ranges from contusion to rupture. Cardiac rupture, however, is un-common and associated with a very high mortality rate ; left ventricular rupture due to falling is even more rare. We experienced a case of left ventricular rupture of the heart caused by a fall, which the patient survived. A 63-year-old man fell off a ladder and presented with hypotension from left hemothorax and pericardial tamponade. The hemothorax was relieved via an emergency closed thoracostomy but dyspnea and hypotension continued. And so, echocardio-graphy was done and pericardial tamponade was detected. Emergency left thoracotomy was done to repair the rupture site. We believe that patients with cardiac rupture who reach the hospital alive can often be saved by prompt diagnosis and immediate surgical treatment.

The electrolytic reduction of a spent oxide fuel involves the liberation of the oxygen in molten LiCl electrolyte, which is a chemically aggressive environment that is excessively corrosive for typical structural materials. Accordingly, it is essential to choose the optimum material for the processing equipment that handles the molten salt. In this study, the corrosion behaviors of Haynes 263, Haynes 75, Inconel 718 and Inconel X-750 in a molten LiCl-Li2O salt under an oxidizing atmosphere were investigated at 650 ℃ for 72 to 216 hrs. The Haynes 263 alloy showed the best corrosion resistance among the examined alloys. The corrosion products of Haynes 263 were Li(Ni,Co)O2 and LiTiO2; those of Haynes 75 were Cr2O3, NiFe2O4, LiNiO2 and Li2NiFe2O4; while Cr2O3, NiFe2O4 and CrNbO4 were identified as the corrosion products of Inconel 718. Inconel X-750 produced Cr2O3, NiFe2O4 and (Cr,Nb,Ti)O2 as its corrosion products. Haynes 263 showed a localized corrosion behavior while Haynes 75, Inconel 718 and Inconel X-750 showed a uniform corrosion behavior.

From Sep. 1985 to Dec. 1998, 2,450 cases of heart operation including 2 cases of orthotopic heart transplantaion were performed in the Department of Cardiothoracic Surgery, Inje Universty, Pusan Paik Hospital The results of retrospective clinical review of them were obtained as follows. 1.Open heart surgery cases and non-open heart surgery cases were 2.290 and 160, respectively. Among the open heart cases, congenital cases and acquired cases were 1,697(74.1%) and 593 (25.9%), respectively. 2.Among the congenital cases, acyanotic cases and cyanotic cases were 1,548(91.2%) and 149(8.8%), respectively. The postoperative hospital mortality was 1.9% (30 cases) in the acynotic group and 16.6% (25 cases) in the cyanotic group. 3.Among the acquired cases, valvular heart disease, coronary artery disease, aortic aneurysm, cardiac tumor, heart transplantation and others were 471 (79.6%), 73(12.1%), 28(4.7%), 15(2.5%), 2(0.3%) and 4(0.7%) cases, respectively. 4.Prosthetic valve replacement (457 case, 97.0%) and valve reconstructive surgery(14 cases, 3.0%) were performed for the valvular diseases. Postoperative hospital mortality of valve surgery and coronary artery bypass surgery was 2.8% (13 cases) and 28.6% (6 cases), respectively. 5.28 cases of aortic aneurysm (ascending or arch aneurysm) were operated under cardiopulmonary bypass. The causes of aneurysm were annuloaortic ectasia(9), dissecting aortic aneurysm(16), and non-dissecting chronic aneurysm(8). The early postoperative hospital mortality was 8 cases(28.6%). 6.Two cases of heart transplantation were performed successfully using Shumway method .The total ischemic time of donor heart was 80 minutes and 50 minutes respectively. 7.Minimally invasive surgery (using lower sternal incision) was performed successfully in the cases of mitral and tricuspid valve diseases(10) and congenital septal defects (20). In conclusion, the over all postoperative hospital mortality was not so high as 3.5 %, whereas more proper management for congenital cyanotic group was seemed to be necessary.

97년 9월 이후 2예의 동소 심장이식수술을 시행하였는데 대상 환자들은 남녀 각 1명, 나이는 여자는 55세, 남자는 23세이고, 체표면적은 각각 1.54m2, 1.62m2였다. 대상환자들은 확장성 심근증과 제한성 심근증 환자로 NYHA IV 정도의 심한 심부전증 증상이 있었다. 수술 후 면역억제제로는 사이클로스포린, 아자티오프린, 스테로이드를 사용하였다. 첫 번째 환자에서는 수술 10일 후 심근조직검사에서 ISHLT 기준의 I 단계의 거부반응을 보였고, 이후의 조직검사에서는 거부반응이 없었으며 술후 2개월째에 대상포진, 8개월째에는 구강 칸디다증으로 입원 치료를 받았다. 두 번째 학자에서는 술후 2일째 사이클로스포린에 의한 신독증을 보였으나, 순조롭게 회복되어 퇴원하였다. Since September 1997, we have performed two cardiac transplantations in one dilated cardiomyopathy and one restrictive cardiomyopathy. The patients were a 55-year-old female and a 23-year-old male, and their body surface area(m2) were 1.51 and 1.62 respectively. Both patients were suffered from dyspnea as NYHA functional class IV. Postoperative immunosuppression was accomplished with cyclosporine, azathioprine and predinisolone. In case 1, there was an ISHLT grade IA rejection in endomyocardial biopsy at postoperative 9th day which disappeared at the tome of next biopsy 20 days later. The patients were treated for herpes zoster and oral candidiasis at postoperaive 2 months and 8 months, respectively. In case 2, nephrotoxicity related to cyclosporine developed 2 days after the surgery, but was soon resolved and the patient was discharged in good condition.

조윤행,홍성수,김은옥,이미숙,김양수,우준희,배직현,류지소 대한화학요법학회 1999 대한화학요법학회지 Vol.17 No.2

저자들은 아직 국내에 보고된 적이 없는 S. typhi에 의한 척추골수염 환자에서 ciprofloxacin을 5주간 투여하여 임상적 호전을 보였던 증례를 경험하였기에 보고하는 바이다. Vertebral osteomyelitis by Salmonella infection is rare. Although it is known to be associated with sickle cell anemia, various hemoglobinopathies and immunosuppressive states, it may also occur in normal host. To date, vertebral osteomyelitis with Salmonella. typhi has not been reported in Korea. We experienced a case of spinal osteomyelitis due to S. typhi in a 48-year old man who was admitted because of low back pain for two months. MRI scan showed vertebral osteomyelitis in L1 & L2. Needle aspiration was performed by CT guidance. S. typhi was identified from aspirated pus. However, any organism was not identified from blood and urine cultures. He was treated with ciprofloxacin for 5 weeks successfully.
