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.

`Background : Pancreatoduodenectomy is a widely used technique in the treatment of periampullary, duodenal and cephalic pancreatic disease. Although many improvements have been made in operative technique and posmiddleerative care, pancreatoduodenectomy remains a technically difficult procedure attended by relatively high morbidity and mortality rates. Materials and methods : The hospital records of 51 patients who underwent pancreatoduodenectomy at the Chosun University Hospital between 1994 and 2001 were reviewed. Clinical data and the following morbidity and mortality were recorded The risk factors were analyzed by a Chi-square test. Results : Fifth decade was the most prevalent ages (43.1%) The mean age was 59 years (ranging from 29 to 78) and the male to female ratio was 26 to 1. The periampullary cancer was the most reason to operation (86%) and injury due to trauma, adenocarcinoma of stomach, colon cancer, chronic pancreatitis in order Posmiddleerative complications were developed in seventeen patients and anastomotic leakage was the most common complication Death within a month after operation was 3 (5.8%) and the one of the cause of death was leakage in two patients, the other cause was intraadbominal bleeding in one patients. The cardiovascular disease, pulomnary problem, diabetes, level of bilirubin were checked preoperatively and showed no statistical difference in the posmiddleerative morbidity. The other factors such as amount of bleeding, operation time were not influencing posmiddleerative complications. The occurrence of leakage in eight cases of drainage tuve inserted into the pancreaticojejunostomy site was not different from no tuve insertion statistically Conclusion: old age of the patients, diabetes mellitus and massive intraoperative hemorrhage are the risk factors influencing the results after pancreatoduodenectomy. Morbidity and mortality after pancreatoduodenctomy can be devreased if a prudent selection of paients is made and the operation is performed by accomplushed surgeon.

목적 : Thromboxan A2의 혀관수축반응을 저해하는 prostacylin synthase exon 8 C117A의 변이가 관동맥 연축과 관련성이 있는지를 알아보고자 하였다. 방법 : 1998년 1월 1일부터 2000년 12월 31일까지 충남대학교병원 순환기내과에서 관동맥조형술과정맥내 에르고노빈 유발검사를 시행하여 관동맥 연축이 확진된 이형협심증 환자군(45예)과 정상 대조군(59예)을 대상으로 중합효소 연쇄반응법 및 restriction fragment length polymorphism을 이용하여 분석하였다. 결과 : Prostacyclin synthase exon 8 C117A 유전자형의 빈도는 대조군에서 A/A : A/C : C/C =3.4% : 30.5% : 66.1%, 이형협심증 환자군에서 A/A : A/C : C/C = 8.9% : 42.4% : 48.9%로 두 군간에 유의한 차이가 없었다. 대조군에 비해 변이형 협심증 환자군에서 남자의 비율과 흡연률이 높았지만, prostacyclin synthase exon 8 C117A 유전자형에 따른 군에서 당뇨병, 고혈압, 흡연, 고지혈증, 비만 등의 유의한 차이는 없었다. 결론 : 한국인에서 prostacyclin synthase exon 8 C117A 유전자 다형성과 관동맥 연축이 있는 이형협심증과의 유의한 연관성은 발견할 수 없었다. Backround : Coronary artery spasm plays an important role in the pathogenesis of variant angina(VA). Prostacyclin is one of the endothelium derived relaxing factors. The association between the novel single nucleotide polymorphism in the prostacyclin synthase gene and VA is not known. Therefore, we investigated the association between VA and the polymorphysm in the prostacyclin synthase gene. Methods : We compared 45 variant angina patients who had positive intravenous ergonovine test by coronary angiography with 59 control subjects who had negative intravenouis ergonovine test and normal coronary angiogram. Using the polymerase chain reaction-single-strand conformation polymorphism analysis, we identified a single nucleotide polymorphism, C117A, in exon 8. This nucleotide change did not cause an amino acid change in codon 373. Results : There was no significant difference in characteristics between the control group and the VA group, and there was no significant difference in the genotype distributions between the control group and the VA group. Conclusion : The C117A polymorphism in exon 8 of the prostacyclin synthase gene is not associated with variant angina.

강원지역 신석기시대 움집터에 대한 고찰

정성희 동의대학교 인문사회연구소 2010 인간과 문화 연구 Vol.17 No.-

Due to the recent developments in rural areas in Korea, Gangwon province has exposed to numerous excavation opportunities that brought new research materials, ideas as well as discussions for the development and characteristics of Neolithic dwelling sites. It appears that the recent discoveries of the dwelling sites are historically significant evidences for over viewing the life and culture of the residents during the period apart from previous methods of object oriented interpretation. Geographically, Gangwon province is divided into eastern (Youngseo) and western (Youngdong) areas by a mountain range called Taebaeksanmaek. From the different living styles and culture developed as a consequence of distinctive geographical and natural environments of the western and eastern areas, it is assumed that during the Neolithic with low mobility, the differences were even more diverse. The most distinctive characteristics are found in the shape and structure of dwelling sites. Therefore the discovery plays central role in the further study and extensive research on the dwelling sites, cultural and historical connections, exchanges and interchanges of the Neolithic period in the area of Gangwon. 최근 대규모 공사에 따른 발굴조사가 활발해지면서 강원지역에서의 신석기시대 움집터 자료의 증가에 따라 강원지역 신석기시대 움집터에 대한 특징 및 변화양상 등의 연구와 논의가 증가하고 있다. 이에 최근 강원지역에서 활발하게 조사된 신석기시대 움집터의 특징과 변화양상에 대한 연구는 기존 토기나 석기 등 유물 중심의 연구에서 벗어나 강원지역 신석기시대 생활과 문화를 종합적으로 복원해볼 수 있는 학술 자료적 가치가 높을 것으로 생각된다. 강원지역은 지형적으로 태백산맥을 중심으로 영동지역과 영서지역으로 나눌 수 있다. 두 지역은 서로 다른 지형과 자연환경의 영향으로 생활권과 문화적 요소가 각각 다른 특징을 보이는데, 교통이 발달하지 못한 신석기시대에는 생활이나 문화적 요소가 더욱 달랐을 것으로 짐작된다. 그 가운데 당시 사람들의 생활 근거지였던 움집터도 그 분포양상이나 구조 등이 서로 다르게 나타나고 있다. 따라서 두 지역 간의 신석기시대 움집터에 대한 구조와 변화양상에 대한 검토를 통하여 강원지역 신석기시대 움집터에 대한 특징과 상호교류 관계, 생활상 등을 살펴볼 수 있는 연구 자료를 제공할 것으로 생각된다.

폐결핵 환자 혈청에서 수용성 Interleukin 2 수용체 및 Adenosine Deaminase 활성도에 관한 연구

고정희,박성규,백상현,박찬권,박병수,안진영,최우석,박정규 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.1

Interleukin-2 (IL-2) induces T cell proliferation in an autocrine manner and provides a means by which antigen triggered T cells can be clonally expanded in vitro. During the following activation, the activity of IL-2 is mediated by specific high affinity IL-2 binding membrane receptors which are expressed shortly after activation. In this process, a 42 KD-fragment (soluble IL-2R) is continuously cleaved off and circulates as a soluble marker of T lymphocyte activation. Elevated level of soluble IL-2R has been identified in the serum of patients with malignant autoimmune and allergic disorders, systemic parasitic infection, undergoing graft versus host disease, acute or chronic lymphocytic leukemia and HIV-infection. ADA (adenosine deaminase) completes the process of differentiation of T cell and is essential for progression of T cell maturation. Therefore level of ADA is to correlated with magnitude of T cell immune response. The fact that expression of sIL-2R and ADA activity increases in peripheral blood T-lymphocytes of patients with active pulmonary tuberculosis suggests that T cell activation might have a major role in the pathogenesis of pulmonary tuberculosis. In order to evaluate the T cell immune response in pulmonary tuberculosis, we measured the serum concentration of sIL-2R and ADA activity in 17 patients with current pulmonary tuberculosis, 10 chronic inactive pulmonary tuberculosis, 10 as normal controls. (1) Current pulmonary tuberculosis had significantly higher levels of sIL-2R (237.24±95.47)when compared with those of inactive tuberculosis (78.6±11.06). and the control (68.17±15.4) group. (2) ADA activity in current pulmonary tuberculosis was significantly increased (34.41±20.63) when compared with those of inactive tuberculosis (24.7±14.36) and control (17.65± 5.94) group. (3) There was good correlation between sIL-2R concentration and ADA activity in serum in current pulmonary tuberculosis group. (4) sIL-2R concentration and ADA activity was decreased significantly 6 months after anti-tuberculosis drug medication. In conclusion, sIL-2R concentration and ADA activity in serum in current pulmonary tuberculosis group was increased when compared with those of inactive pulmonary tuberculosis and the control group. By the way, T cell mediated immune response was enhanced in current pulmonary tuberculosis, but in inactive chronic pulmonary tuberculosis who had treated by antituberculosis drug medication, the concentration of sIL-2R and ADA activity was nearly normal.

정자기장과 맥동전자기장이 배양 조골세포에 미치는 영향을 알아보고자 MC3T3-E1세포를 각 자기장하에서 배양하여 ALP활성도와 DNA의 합성능을 평가한 결과 다음과 같은 결과를 얻었다. 1. 정자기장을 가한 군에서 자석을 1,2,3개 가한 군(51~114.8mT)에서 대조군에 비하여 ALP의 유의성있는 증가가 나타났으며(p<0.05), 자석을 4개, 5개 가한 군(150mT)에서는 대조군에 비하여 ALP활성도에 차이가 나타나지 않았다. 2. 맥동성 전자기장에서는 대조군에 비하여 ALP활성도에 유의한 차이가 나타나지 않았다. 3. DNA합성능은 정자기장과 맥동성 전자기장을 가한 군 모두 대조군에 비하여 유의한 차이가 나타나지 않았다. 이상의 결과 정자기장에 의한 교정력은 골세포의 대사과정에 변화를 줄 수 있으므로, 치아이동에 어떠한 영향을 줄 수 있을 것으로 사료된다. The purpose of this study was to evaluate the effect of magnetic field on cellular activity of MC3T3-E1 cells. The celular activity was monitored by alkaline phosphatase and DNA synthetic activity in control, static magnetic field and pulsed electromagnetic field groups. A static magnetic field and pulsed electromagnetic field groups. A static magnetic field was applied to the cell by placing one, two, three, foue, and five samarium-cobalt magnets above and below each cell plate for 24hours per day. A pulsed electromagnetic field with a frequency of 100 herz was applied for 10 hours per day. After 10 days of magnetic field exposure, there were increase of alkaline phosphatase activity in static magnetic field groups consisted of one, two and three magnetic groups. Alkaline phosphaatase activities were not significant increase in alkaline phosphatase activity compared to control. DNA synthetic activity in both static and pulsed electromagnetic field group were not significantly different from that in control group. The result of this study suggest that magnetic field could have effect on the metabolism of bone cells related to the cellular metabolic process.
