        단백질 S 결핍증에 의한 장간막정맥혈전증 치험 1예

        김용신,박창영,손정일,김병익,서원태,김명숙,전우규,정을순,김흥대 대한소화기학회 1999 대한소화기학회지 Vol.34 No.6

        Mesenteric venous thrombosis is rare but clinically important because it can cause ischemia or infarction in the small intestine. Unless it is diagnosed in time, the patient die eventually. However, the diagnosis is difficult because patients often present with nonspecific abdominal symptoms. Furthermore, if it occurs in young individuals without any known predisposing factor, the diagnosis may become more difficult. Recently, the development of modern imaging techniques (particularly ultrasonography, duplex scanning, and computed tomography) have enabled early recognition of this disease. We report a case of mesenteric venous thrombosis and deep vein thrombosis of left lower extremity. A patient was admitted to our hospital due to continuous, dull abdominal pain. The simple abdomen examination showed abnormal gas pattern probably due to small bowel edema. Abdominal computerized tomography revealed mesenteric venous thrombosis with bowel wall thickenings. Bowel resection was performed and the patient was recovered soon. Mesenteric venous thrombosis was known to be secondary to protein S deficiency later.

        홍순우(Soon Woo Hong),김종진(Chong Chin Kim) 한국식물학회 1960 Journal of Plant Biology Vol.3 No.1

        HONG, Soon-Woo, & KIM, Chong-Chin: A study of virus disease on chinese date tree (I). On the external and the internal morphogical characteristics of disease inrected plants. Kor. Jour. Bot. 3 (1). 32-38. 1960 Since the peeuliar virus disease of chinese date tree (Zizyphus jujuba Mill. var. inermis Rehd.) has been noted in South Korea around 1950, 70% to 80% of the economically important trees have been either completely destroyed or infected with the virus, severe damage has been noted, particularly, across the area ranged from middle east to the middle part of Korea, including Seoul area. Yoon,-Koock-Byung in 1958 first reported the disease and described it might be caused by a kind of yellows. But he did not conform in his paper that the disease is pecisely caused by yellows virus. The authors, hereby intend to identify the true cause of the disease of the chinese date tree by studying the external symptoms of the disease and the internal morphological characteristics of the diseaset plant which shows various abnormalities in contrast to the healthy checks. In view of fact that the leaves of the infected plants become yellowish in color similar to the peach yellows, aster yellows, it is likely to be identifiable as the common yellows. Furthermore, the abnormal characteristics observed by the authors are as follow: The floral organs such as petals, sepald, stamens, and pistil turn into vegetative leaves, the leaves on heavily infected plant appear as small sized one and also showing as a common witch`s broom like symptom. There are also an occuring of numerous advantitious shoots developed from both of stems and roots. The amount of photosynthetc starch grains increses iIn parenchymatous cells, necrosis takes place in mesophyll, Partlcularly, Palisade Parenchyma in the leaves of infected plants are distinguished in contrast to the healthy checks. From the symptoms and the present experiments described above, the authors are belived that the disease of chinese date tree is not caused by the yellows. It appears the disease is rather similar to the symptoms of sandal spike virus which was noted in India early in this centry. But the host plant of sandal disease, Santalum album L. and the insect vector, Jassus indicus Wal., have never been reported in Korean flora and the founa. The temperature and the other environmental factors is auite different Korea ard India. Thus the authors believe that the peculiar disease must be an endemic new virus origin in Korea and must be called as shoot cluster disease of chinese date tree.

      • 顎關節機能장애 珍斷을 爲한 頭部軸方向放射線寫眞에서의 下顎顆頭의 位置分析

        金碩鎬,卞種秀,崔珣哲 慶北大學校 齒科大學 1986 慶北齒大論文集 Vol.3 No.1

        著者는 顎關節機能障碍의 소견을 가진 환자 75명과 악관절기능장애의 炳歷 및 現症이 없는 정상인 75명을 표준화된 조건하에서 頭部軸方向放射線撮影을 하여 顆頭水平角과 initial 및 final depth of cut를 측정하고 통계학적으로 분석한 결과를 다음과 같이 요약할 수 있었다. 환자군과 정상군, 患側과 非患側에 있어 顆頭水平角과 initial 및 final depth of cut는 통계학적으로 유의한 차가 없었으므로 頭部軸方向放射線寫眞은 임상에서 악관절기능장애의 유무 및 患側과 非患側의 감별에 이용하기에는 부적합한 방법이라 사료된다. 본 연구의 계측치는 편차가 심하므로 환자마다 顆頭水平角을 측정하여 이각에 맞추어 顎關節斷層撮影을 해야 한다고 사료된다. The purpose of this study was to analyze the position of mandibular condyle on the submentovertex radiograph, thereafter to evaluate the usefulness of submentovertex radiograph in diagnosis of temporomandibular joint dysfunction, and to check the best method of tomographic techniques. Submentovertex radiographs which were taken in 75 tempormandibular joint dysfuction patients and 75 normal persons were used as the sample for this study. The obstients results were as follows : The submentovertex radiograph was a improper method in diagnosis of temporomandibular joint dysfuction and discrimination of affected side. The selective tomography was a better method than any other temographic techniques in diagnosis of temporomandibular joint dysfunction.

        수지상세포의 방사선 저항성에 대한 연구

        김은실,김종순,이명호,범희승,민정준,정환정,김성민,허영준,송호천,이제중 대한핵의학회 2003 핵의학 분자영상 Vol.37 No.3

        목적 : 림프구와 비교되는 수지상 세포의 방사선 민감성을 보기 위하여 본 연구를 시행하였다. 대상 및 방법 : 말초혈액에서 분리한 T 림프구에 0 Gy, 10 Gy, 30 Gy의 방사선을 조사하고 4시간 후에 유세포 분석기를 이용하여 선량별 세포고사 빈도를 관찰하였다. 또한 조혈모세포에서 미성숙 및 성숙 수지상 세포를 단계적으로 분리 배양하여 각각 0 Gy, 10 Gy, 30 Gy, 100 Gy의 방사선을 조사하고 4시간, 24시간 그리고 48 시간 후에 선량별 세포고사 빈도를 관찰하였다. 사이토스핀(cytospin)슬라이드에 림프구와 미성숙 및 성숙 수지상세포를 3×104개 씩 분주하고 May Grunwald-Giemsa 염색한 후, 광학 현미경 하에서 각각의 세포군 당 100개의 세포에서 세포 면적당 핵의 면적 비를 측정하였다. 결과 : 림프구에서는 방사선조사 선량별로 세포고사 빈도가 유의하게 증가하였으나, 수지상 세포에서는 그 분화정도나 방사선조사 선량에 따른 세포고사의 빈도차이가 없었다. 또한 수지상 세포는 방사선선량과 관계없이 용량에 의존적으로 강력한 T-세포 자극능을 보였다. 림프구의 세포에 대한 핵의 면적 비는 미성숙 및 성숙 수지상세포의 세포에 대한 핵의 면적 비보다 현저히 큰 반면, 두 가지 수지상세포간에 유의한 차이는 없었다. 결론 : 수지상세포는 그 분화도와 상관없이 림프구에 비하여 방사선 저항성을 나타내었고, 이는 세포의 형태적 차이에 따른 표적의 크기와 관련이 있을 것으로 생각되며, 향후 분자 생물학적인 연구의 기초 자료로 활용할 수 있을 것으로 생각된다. Purpose : To evaluate radiation sensitivity of dendritic cells in comparison with lymphocytes. Materials and methods : T lymphocytes captured from peripheral blood were irradiated by 0 Gy, 10 Gy, 30Gy. Apoptosis was measured by flowcytometry for staining of Annexin V 4 hours after irradiation. Immature and mature dendritic cells processed from blood hematopoietic stern cell were irradiated by 0 Gy, 10 Gy, 30 Gy, 100 Gy respectively and apoptosis was measured by flowcytometry with time difference as 4h, 24h and 48h after irradiation. Morphometric analysis by percent nucleus was measured in three cell groups, also. Results : Lymphocytes showed radiation sensitivity by increasing apoptotic fraction according to radiation dose. However, both mature and immature dendritic cells showed consistent fraction of apoptosis in spite of increasing radiation dose. Percent nucleus ratio is significantly higher in lymphocytes than that of mature or immature dendritic cells. Stimulation of T-cell by dendritic cells was not changed after irradiation. Conclusion : Dendritic cells showed radioresistance which was associated with small size of nucleus in comparison with lymphocytes and this result would be used as a basal data of radio-labelling for the cellular trafficking studies in nuclear medicine fields.
