Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

목적 : 기관지내시경 검사에서 흔히 사용되는 국소마취제인 lidocaine과 내시경시 지혈목적으로 사용되는 thrombin과 epinephrine이 각종 균주에 미치는 항균효과에 대해 알아보고자 하였다. 재료 및 방법 : 균주는 가톨릭대학교 성모병원에서 2004년 3월부터 2004년 9월까지 임상검체 에서 동정된 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 각각 42, 42, 42, 43주를 대상으로 하였다. Lidocaine, thrombin, epinephrine 감수성 검사는 National Committee for Clinical Laboratory Standards (NCCLS, 2002)의 기준에 따랐다. 결과 : Lidocaine은 S. aureus, S. pneumoniae, P. aeruginosa에서 MIC_(50), MIC_(90) 모두 20,000 ㎍/mL 이었다. K. pneumoniae는 각각 10,000 ㎍/mL이었다. Thrombin은 S. aureus와 P. aeruginosa에서 MIC50 500 lU/mL 과 MIC_(90) 500 IU/mL 이상이었고, K. pneumoniae에서는 MIC_(50)과 MIC_(90)이 모두 500 lU/mL이상이었으나 S. pneumoniae에서는 MIC_(50)과 MIC_(90)은 125 IU/mL이었다. Epinephrine은 K. pneumoniae, S. pneumoniae에 대한 MIC_(50), MIC_(90)가 모두 >500 ㎍/mL이었고, S. aureus와 P. aeruginosa에 대한 MIC_(50), MIC_(90)가 모두 500 ㎍/mL이었다. 결론 : 기관지 내시경 검사에서 흔히 쓰이는 lidocaine, thrombin, epinephrine 등의 약제들이 호흡기 질환의 흔한 병원균인 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 균주들에 대해 항균 효과가 있을 수 있어 세균배양검사에 영향을 미칠 수 있겠다. Background : We performed this stody to find out about antimicrobial effect of lidocaine which is commonly used local anesthetic, and thrombin and epinephrine used for hemostasis during bronchoscopic procedures. Materials and Methods : The microorganisms that were cultured from specimens obtained during bronchoscopy were Staphylococcus aureus (n=42), Streptococcus pneumoniae (n=42), Klebsiella pneumoniae (n=42), and Pseudomonas aeruginosa (n=43) collected from St. Mary's Hospital, from March to Sep 2004 were used for susceptibity testing. Susceptibility to lidocaine, thrombin, and epinephrine were tested according to the National Committee for Clinical Laboratory Standards. Result : MIC_(50) and MIC_(90) of lidocaine for S. aureus, S. pneumoniae, P. aeruginosa were all 20,000 ㎍/mL and that for K. pneumoniae were 10,000 ㎍/mL. MIC_(50) and MIC_(90) of thrombin for both S. aureus and P. aeruginosa was 500 IU/mL and above 500 IU/mL, respectively; that for K. pneumoniae were all above 500 IU/mL and for S. pneumoniae they were 125 IU/mL, MIC_(50) and MIC_(90) of epinephrine for K. pneumoniae and S. pneumoniae were above 500 ㎍/mL; that for S. aureus and P. aeruginosa were 500 ㎍/mL. Conclusion : We observed possible antimicrobial effect of lidocaine, thrombin, and epinephrine in vitro against pathogens such as S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa, which are common respiratory microorganisms. The use of these agants could affect the result of bacterial culture.

We performed a variety of lymphocyte stimulation tests, delayed hypersensitivity skin tests, and enumeration of several lymphocyte subpopulations in 21 patients with gastric cancer who did not receive any form of anticancer therapy, and in 20 healthy controls. The gastric cancer patients had significantly decreased number and total score of positive reactions in delayed hypersensitivity skin tests compared with the healthy controls. The percent of CD_(4) positive lymphocytes in the gastric cancer patients was significantly decreased compared to the normal control subjects, but it had no correlation with the total score of delayed cutaneous hypersensitivity reactions. The ratio of helper to suppressor cells was lower in the cancer group. The uptake of 3H-thymidine was markedly depressed in cancer patients when stimulated with various mitogens. There was little correlation between any of the stimulation tests and any of the lymphocyte subpopulation proportions to delayed hypersensitivity cutaneous reactions. Optimal proliferative response was found in lymphocytes stimulated with 10 micrograms of concanavalin-A and 10 microgram of phytohemagglutinin. Advanced stage patients had greatly depressed delayed hypersensitivity skin reactions and proliferative responses to mitogens compared with localized diseases. These results suggest that gastric cancer patients have depressed cellular immune functions, which mainly result from the decreased helper cells and defects in functional proliferative response to mitogens. Interleukin-2 and interferon-gamma restored the in vitro proliferative response of lymphocyte in patients with gastric cancer.

Grid computing is an emerging technology that promise to unify resources and computing power in many organizations together. It couples a wide variety of geographically distributed computational resources, and presents them as a unified integrated high-end computer. The Globus Resource Allocation and Management(GRAM) service provides for the management and remote execution of jobs defined using a standard Resource Specification Language(RSL) requested by client in grid environment. However, Currently the GRAM has very limited functionality to support for applications that required special execution environment. Here, we provide a proposal for Execution Environment Information interacted with broker to support the GRAM's special execution environment.

저자들은 최근 화농성 슬관절염과 병발한 수막구균성 수막염 1예를 체험하였고, 이는 국내에서 아직 보고되지 않은 드문 예로 사료되어 문헌고찰과 함께 보고하는 바이다. We recently experienced a case of meningococcal meningitis associated with pyogenic arthritis in a 37-year old male patient. Pyogenic arthritis developed in right knee joint during treatment for meningococcal meningitis. He was treated successfully by appropriate antibiotics and arthroscopic irrigation. To our knowledge, such a rare case has not ever been reported in Korea, Hence we report this case with a review of related literatures.

해양스포츠 이벤트가 지역경제변동에 미친 영향 : 거제시의「바다로 세계로」

김희중,김정완 창원대학교 체육과학연구소 2002 경남 체육연구 Vol.7 No.2

본 연구는 거제시의 해양스포츠 「바다로 세계로」축제가 지역사회의 경제변동에 미친 영향을 규명하는데 그 목적이 있다. 이를 위해 본 연구의 주제와 관련된 주민의식조사를 실시하였다. 연구의 대상은 거제시에 거주하고 있는 주민들 중에서 20-65세 미만의 남·여 404명이며, 이를 무작위 추출방법으로 표집하였다. 수집된 자료를 분석하여 얻은 연구결과는 다음과 같다. 첫째, 「바다로 세계로」해양스포츠 축제가 지역사회의 경제변동에 미친 영향에 대한 주민의식조사 결과 지역홍보가 3.62, 관광자원 개발 3.44, 관광수입증대 3.39, 재정확대 3.22, 경제성장영향 3.22, 특산품 시장 확대 3.15, 지역 기업의 인지도 향상 302., 도로·교통망 확대 3.08 등의 순으로 긍정적 인식도를 나타내었다. 그리고 긍정적으로 인식하지 않고 있는 변수는 고용 확대 2.94, 부동 가격 상승 2.94 등으로 나타났다. 둘째, 일반적 특성에 따른 각 변수에 대한 의식 차이를 검증한 결과 성별, 연령별, 거주기간별 특성에서는 전 변수에 유의한 차이가 없는 것으로 나타났다. 그러나 학력별 특성에서는 대졸이상이 3.86으로 전체평균 3.62보다 높게 지역 홍보에 긍정적 영향을 미친 것으로 인식하고 있다. 그리고 중졸 3.60, 고졸 3.56 순으로 나타났다. 따라서 장기적으로 경제분야 뿐만 아니라 사회·문화 부분까지 연구가 이루어져야 하며, 또한 이러한 의식은 시대의 흐름에 따라 동태적으로 변화는 특성을 지니므로 이에 대한 종단적이고 시계열적인 연구가 계속적으로 진행되어야 할 것이다.

The purpose of this study was to longitudinally analyze influences of functional prefrontal lobe on science achievement in middle school students. In this longitudinal study, 47 students(male 19, female 27) were sampled in local area. The students were administered test of GALT(group assessment of logical thinking), CTST(classroom test of scientific test), FIT(figural intersection test), GEFT(group embedded figural intersection test), TOL(tower of London), WCST(Wisconsin card sorting test) at December 1997 and 1999. It is substitute science achievement for science grade each year. The resulted that prefrontal lobe was influenced upon science achievement. Science achievement statistically significant correlated with functional prefrontal lobe, specially logical thinking level, scientific reasoning, perseveration error. And, the development of functional prefrontal lobe functions did not only linear, but also each function has differ with development speed and period. School science classroom was suited high level students. Who has been grade C and D in first-grade, they did not improved. A first-grade achievement effect on science achievement. And also scientific reasoning ability effect on science achievement.
