Activities of serum glutamic pyruvic transaminase [SGPT], serum glutamic oxaloacetic transaminase [SGOT] and serum lactic dehydrogenase [LDH] were determined during and after surgery In a total of 18 patients with heart diseases Including 8 cases of congenital heart anomaly and 10 cases of acquired valvular diseases who undergone open heart surgery under cardiopulmonary bypass. The results obtained are as follows: 1]The average value of the activity of SGPT before the surgery was $27.94{\pm}12.24$ units. The value was increased following the operation and reached to the maximum value of $43.83{\pm}37.02$ units 2 days after the operation, which was slightly deviated from the normal range. The enzyme activity returned to the normal range of $32.82{\pm}23.61$ units 4 days after the operation. 2]The average value of the activity of SGOT before the surgery was observed to be $30.5{\pm}11.29$ units. The value increased during the operation and reached to the maximum value of $95.56{\pm}43.38$ units. 2 days after the operation, the enzyme activity was gradually decreased thereafter and returned to the normal range 6 days after the operation. 3]The average value of the activity of serum LDH before the surgery was found to be $258.0{\pm}88.96$ units. The value was increased during the operation and reached to the maximum value of $930.55{\pm} 258.23$ units 2 days after the operation. The enzyme activity was gradually decreased thereafter and returned to normal range 7 days after the operation. 4]It was observed that the longer the time required for the extracorporeal circulation in the open heart surgery became, the greater the changed in activity of SGOT, SGPT and serum LDH were found.

This is a report of a chylous cyst in the mediastinum found in a 61 year old Korean female patient who suffered from mild swallowing difficulty and right chest discomfort. These symptoms had developed 5 years previously when chest P-A view showed thumb-tip sized mass shadow in right mediastinum, just right to ascending aorta. Esophagogram revealed an indentation of midesophagus. Follow up checks showed growing mass shadow which suggested aneurysm of ascending aorta. On admission chest X-ray revealed a well circumscribed infant head sized mass density along the right heart border and middle mediastinal border, and extended near to the middle clavicular line in right chest cavity. Aortogram revealed no relationship between the mass and aorta. Right thoracotomy was performed under impression of mediastinal tumor. There was a large cyst containing 700 cc of milky fluid. There was no connection to the thoracic duct nor adjacent organs. The fluid was analyzed chemically and identified the fluid as chyle. The origin of the isolated chylous cyst was uncertain postoperative course was uneventful.

현재의 도시 계획은 자동차의 증가, 도심녹지의 부족, 기존 도심의 공동화 현상 등 많은 문제를 낳고 있다. 우리가 선정한 대상지의 경우 쌍용동, 두정동 일대의 대규모 서부축 택지 개발과 시청의 이전으로 인해 기존 행정, 상업의 중심지였던 천안역 일대의 공동화 현상이 발생하였다. 그렇기 때문에 이런 배경을 조건으로 천안시 구도심의 공동화 원인과 실태를 파악하고 구도심의 상권 활성화에 초점을 두고 실질적인 구도심 활성화 방안에 대해 연구한다.

본 논문에서는 Uruguay Round(이하 UR)의 농업분야 타결내용 가운데 관세화와 보조금 삭감의 농업생산과 소비 및 수출입(국제수지) 효과의 파악에 목적을 두었다. 구체적으로는 정부가 UR이행계획서에 따라 시행하고 있는 보리, 감자 등 6개품목에 대한 관세상당치 1% 감축과 고추, 참깨 등 4개 품목에 대한 상한양허관세 1% 삭감, 그리고 쌀, 보리, 콩 및 옥수수 등 4개 품목에 대한 보조금 1.33%의 감축효과를 측정하였다. 1990년 산업연관표를 토대로 일반균형연산모형을 설정하여 분석한 결과 연간 무역수지는 약 1억 달러의 적자가 야기되고 여타 농축산물 분야에서도 이와 비슷한 정도의 적자가 초래될 것으로 추정되었다. 품목별로는 쌀과 보리, 그리고 수입비중이 큰 옥수수와 콩 등 4개 품목에서 1억 달러를 상회하는 무역적자가 발생할 것으로 나타났다. 그러나 농산물의 수입증대로 제조업 분야에서는 수출이 약 28억 달러가 증가하는 데 힘입어 국민경제 전체적으로는 농업개방에 따라 약 13억 달러의 무역흑자가 발생할 것으로 전망되었다.
