Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

Streptozotocin-당뇨병 백서에서 당뇨병 이환기간에 따른 대동맥의 이완능 저하 및 Oxygen-Free Radical에 의한 이완능의 손상정도

김정국,김신우,김수동,서예경,하승우,김보완,백운이,권삼,강승완 경북대학교 병원 1997 경북대학교병원의학연구소논문집 Vol.1 No.1

목적: 당뇨병의 이환기간이 혈관의 내피세포 의존성 및 비의존성 이완능의 저하에 미치는 영향과 이환기간에 따라 oxygen-free radical(OFR)에 의한 동맥이완능의 손상정도에 차이가 있는지를 알아보고자 하였다. 방법: Streptozotocin(STZ)으로 당뇨병이 유도된 3 주 및 10주째의 백서군과 연령이 비슷한 정상 대조백서군의 적출 대동맥환을 norepinephrine으로 수축시킨 상태에서 내피세포 의존성 이완제인 acetylcholine(ACh) 및 비의존성 이완제인 nitroglycerine(NTG)에 대한 이완능을 즉정하여 비교 관찬하였다. 또한 xanthine과 xanthine oxidase의 혼합으로 생성된 H₂O₂에 대동맥환을 노출시킨뒤 역시 ACh과 NTG에 대한 이완능의 손상정도를 비교하였다. 결과: 3주및 10주째 당뇨병 백서의 대동맥환은 모두 대조군 백서의 대동맥환에 비해 ACh에 대한 이완능이 유의하게 감소하였으며 10주째 당뇨병 백서군에서의 ACh에대한 이완능의 저하는 3 주째 당뇨병 백서군에 비해 유의하게 심하였다.H₂O₂에 노출시킨 뒤 ACh에대한 이완능은 3주 및 10주 째 당뇨병 백서군에서 모두 대조군에 비해 유의하게 심한 손상을 보였으나 3주와 10주째 당뇨병 백서군 사이의 손상정도의 차이가 통계학적으로 유의하지는 않았다. 한편 3주 및 10주째 당뇨병 백서군 모두 NTH에 대한 대동맥환의 이완능은 대조 백서군과 별다른 차이가 없었으며 또 H₂O₂에 노출시킨 뒤에도 NTG에 대한 이완능의 손상은 관찰되지 않았다. 결론: STZ-당뇨병백서에서 대동맥의 이완능은 당뇨병에 이환된지 3 주째에 이미 ACh에 대한 내피세포 의존성 이완능이 선택적으로 저하되며 당뇨병의 이환기간이 길수록 이완능의 저하가 심하였고, OFR에 의한 동맥 이완능의 손상도 내피세포 의존성 이완능에만 선택적으로 나타나나 이환기간에 따라 OFR에 의한 이완능 손상정도에는 뚜렷한 차이가 없음을 시사하고 있다. Objectives: Diabetes mellitus produces histological evidence of endothelial as well as changes in vascular function in experimental animal. Oxygen free radicals interfere with of destroy endothelium-dependent relaxation in normal and diabetic blood vessels. The present study was investigated whether the duration of diabetic state can affect the severity of impairment in endothelium-dependent and/or independent relaxation and the sensitivity to oxygen free fadical (OFR)-induced damage in diabetic rat vasculature. Methods: The relaxative responses of aortic ring precontracted with norepinephrine in vitro to cumulative concentrations of acetylcholine (ACh) and nitroglycerine (NTG) were conducted in 3- and 10- week streptozotocin (STZ)-diabetic rats and agematched controls. After exposure to H₂O₂generated by mixing xanthine and xanthine oxidase, the degree of impairment in relaxative responses to ACh and NTG were also compared between 3- and 10-week diabetic rats. Results: The relaxative responses of aortic rings produced by cumulative concentrations of ACh were significantly lower in both 3- and 10-week diabetic rats than in the age-matched controls. The impairments of relaxative responses to ACh in 10-week diabetic rats were significantly greater than those in 3-week ones. After H₂O₂ exposure, the impairments of relaxative responses to ACh in 3- and 10-week diabetic aortas was also significantly greater than those in the control in the control ones. However, the severity of H₂O₂-induced damage in 10-week diabetic aortas was not significantly different than that in 3-week ones. In contrast, aortic rings of 3- and 10-week diabetic rats could still be fully relaxed by NTG, even after exposure to H₂O₂. Conclusion: These findings suggest that in SRZ-diabetic rat aortas selective impairment of endothelium-dependent relaxation to Ach can be found early even over a 3-week period after the induction of diabetes and the impairment may be greater in those with the longer duration of the diabetic state and that the impairment of the vascular relaxation by OFR is also selective to endothelium-dependent response but the sensitivity of OFR-induced damage may not be related to the duration of the diabetic state.

The objective of this study was to investigate the managing realities of EVD and provide a descriptive survey with the attempt to obtain basic data needed for the standardization of EVD management. For that purpose, 220 questionnaire copies were distributed to those nurses who were working with intensive care units at university hospitals, general hospitals, semi-general hospitals in Seoul, Kyongki-de and local areas. Of 158 returned questionnaire copies, 139 were used for analysis. Data were collected during the term of academic seminars of Neurosurgery Nursing Committee and KICA (Korea Intensive Care Association), ranging from Oct. 26 through 27. 2000. The tools utilized a structured questionnaire form consisting of 21 questions on general characteristics, the level of understanding, the level of work performance, standard management guidelines, etc. The data collected were analysed with frequency, percentage, mean vague, chi -square test using the SPSS 10.0 program Findings were revealed, as follows: For managing the prevention of EVD infection, aseptic technique was found to be of the most importance (48.9%),'the technique should be carried out at an operation room'(92.8%), but it was actually performed at intensive care units (over 51.5%). 'The term of antibiotics use should be less than 7 days' (81.8%), while it was actually executed for less than 7 days (49.5%). 'The proper time of quittance from it should be within less than 7 days'(74.1%) but actual quittance was executed only by 51.1%. 'Set exchange is needed' by 54.0% but actual exchange was implemented merely by 28.1%. 'The subject of management should be nurses' was reflected by 40% but actually 52.0% were carried out. As a result of hating analysed the understanding of the management of EVD by general characteristics, a significant difference was found in the necessity for set exchange by hospitals, in the time of quittance of a catheter, and in ablution items by work experience. The result of hating analysed the work performance levels of EVD management by general characteristics revealed that a significant difference in administration facilities of medicine by the classification of hospitals, especially the use of antibiotics and the quitting time of a catheter by the classification of intensive care units, and in the use of antibiotics and ablution items by the standard management guidelines.

Park, Woon-Yong,Song, Youn-Kyung,Bae, Kyung-Ho,Kim, Yong-Suk 東亞大學校 建設技術硏究所 2005 硏究論文集 Vol.28 No.2

Currently, digital maps in the metropolitan area are supposed to be revised and renewed every two years, but it is difficulty for the renewal of current information to keep pace with the quickly changing society and so, one of the alternative methods being discussed is a digital map produced using high resolution satellites. The biggest problem in the production of digital maps using high resolution satellite images is the difficulty of production in vector resource format through edge detection of satellite images, a Raster data. In this study, topographical boundaries were detected through edge detection of the satellite image, and after vectorliezing using the screen digitizing method, the results were evaluated and compared to the digital map from the NGII(National Geographic Information Institute) for accuracy.

오승준,김영설,박철영,김덕윤,김성운,양인명,김진우,최영길,팽정령,정경천 대한비만학회 2000 The Korean journal of obesity Vol.9 No.2

연구배경 : 혈전현상을 특징으로 하는 질환에서는 Plasminogen activator inhibitor-1 (PAI-1) 이 높은 활성도를 보이는데, PAI-1 치는 당뇨병, 심근경색증, 비만 등에서 높다고 밝혀진 바 있다. 또한 당뇨병 환자들의 합병증의 주요한 병인은 죽상경화증으로 혈전현상이 특징인 질환에서 증가하는 PAI-1이 당뇨병 환자에서 높다. 목적 : 정상인에서의 PAI-1 유전자 촉진자의 유전자형의 분포 및 혈액농도를 관찰하고, 당뇨병 및 뇌혈관 질환 환자군에서의 PAI-1 유전자 촉진자 유전자형의 분포 및 혈액농도를 측정하여 정상인과 차이점을 알아본다. 당뇨병 환자군에서의 혈장 PAI-1 치와 인슐린 저항성, 전구 인슐린 등과의 상관관계를 살펴보고, 인슐린저항성과 대혈관질환의 지표로 사용될 수 있는지 알아보았다. 방법 : 대상으로는 정상인 76명, 제2형 당뇨병 환자 56명, 뇌혈관질환이 동반된 제2형 당뇨병 환자 48명, 뇌혈관질환 환자 51명을 선택하여, 환자의 혈액에서 인슐린, 공복시 혈당, 전구인슐린, 중성지방, 총콜레스테롤 및 기타 생화학 검사 및 이학적 검사를 시행하였다. 환자의 DNA를 채취하여 전사개시 -675bp를 포함하는 대립형질 특이 시발체를 사용하여 중합효소 연쇄 반응을 실시하여, 그 유전자형을 판독하였다. 결과 : 정상 대조군 76명 (46.4±11.1세), 2형 당뇨병 환자 56명 (58.3±12.6세), 뇌경색증 환자 51명 (63.1±13.2세) 대상으로 하였다. PAI-1 촉진자 유전자형의 (4G/4G, 4G/5G, 5G/5G)빈도는 정상 대조군이 각각 23.7%, 75.0%, 1.3%, 뇌경색 환자군이 19.6%, 66.7%, 13.7%, 뇌경색이 동반된 당뇨병 환자군이 33.3%, 58.3%, 8.3% 였다. (X2=12.6, p=0.05). 이러한 사실은 서구인에 비해 4G/4G, 5G/5G 동형 유전자형이 낮은 결과였다. 각 군별 혈장 PAI-1 농도는 정상 대조군 13.4, 1.8 ~ 65.2 ng/mL (중앙값 , 범위 ) 2형 당뇨병 환자군 14.4, 2.9 ~ 47.8 ng/mL, 뇌경색 환자군 21.9, 6.2 ~ 154.7 ng/mL , 뇌경색이 동반된 2형 당뇨병 환자군 28.8, 3.2 ~ 139.3 ng/mL 로 차이를 보였다 (p=0.000). 전체 대상에서 PAI-1 촉진자 부위의 유전자형에 따른 PAI-1 활성도와 항원 농도는 차이를 보이지 않았다. 그러나 PAI-1 활성도는 혈중 중성지방, 전구인슐린, 체질량지수와 독립적인 상관관계를 보였다 (p=0.000, p=0.000 and p=0.005). 결론 : 결론적으로 PAI-1 촉진자 부위의 유전자형은 뇌경색증의 지표는 아니며, PAI-1 활성도를 결정짓는 인자는 유전적 요인보다는 혈중 중성지방, 전구 인슐린, 체질량지수와 같은 대사적 요인으로 생각된다. Plasminogen activator inhibitor-1 (PAI-1) is known be related to insulin resistance and several components of the large vascular disease. Notably, the high frequencies of diseases such as coronary heart disease or stroke are related to type 2 diabetes complications. We studied to find out whether the PAI-1 promother genotype could be a marker for cerebral infarction in type 2 patients. Subject patients were; 56 type 2 diabetics (age 58.3±12.6), 51 patients with cerebral infarction (age 63.1±13.2), 48 type 2 diabetics with cerebral infarction (age 64.8±9.3) , and 76 healthy control (age 46.4±11.1). The 4G/5G genotype of PAI-1 promoter was evaluated by polymerase chain reaction and endonuclease digestion. PAI-1 promoter genotype frequency (4G/4G, 4G/5G, 5G/5G) was 23.7%, 75.0% and 1.3% in healthy control, 17.9%, 67.9% and 14.3% in type 2 diabetes patients, 19.6%, 66.7% and 13.7% in cerebral infarction patients, 33.3%, 58.3% and 8.3% in type 2 diabetics with cerebral infarction (X^2=12.6, p=0.05). This finding is lower in frequency of 5G/5G homozygote than that reported in Caucasians. The plasma PAI-1 concentrations according to the disease were 13.4, 1.8 ~ 65.2 ng/mL (median, range) for healthy control, 14.4, 2.9 ~ 47.8 ng/mL for type 2 diabetes, 21.9 6.2 ~ 154.7 ng/mL for cerebral infarction , and 28.8, 3.2 ~ 139.3 ng/mL, for cerebral infarction with type 2 diabetes (p=0.000). In the all subjects, PAI-1 concentration and activity of PAI-1 promoter genotype did not show any significant difference. However, the PAI-1 activity was independently associated with serum triglyceride level, plasma proinsulin and BMI (p=0.000, p=0.000 and p=0.005 respectively). We concluded that PAI-1 genotype is not a marker for the cerebral infarction ; however, the genotype is related to PAI-1 concentration , and therefore it seems to be that metabolic factors such as triglyceride level or plasma proinsulin or BMI are more in relations with determining the PAI-1 concentration than the genotype.

본 연구는 국내와 외국의 건물 내장재 화재성능평가방법을 고찰하고 국내에는 도입되지 않은 실대 화재 실험인 Room Corner Test를 국내 내장재중 석고보드와 합판을 대상으로 그 적용성을 위한 실험을 진행하였다. 현재 국내 내장재의 평가규정은 Bench-Scale Test에 의존하고 있으나, 미국, 일본 유럽등에서는 Room Corner Test를 적용한 실질적인 재료의 화재성능평가를 시행하고 있다. 실험 결과, NFPA 265에 의한 석고보드 및 ISO 9705에 의한 합판의 성능은 양호한 것으로 판단되었다. 현재 국내 내장재에 적용되는 등급분류의 평가방법은 재료의 실제 화재성능 평가에 한계가 있으므로 향후 Room Corner Test의 적용과 더불어 Bench-Scale Test 결과를 토대로 화재성능을 예측하는 화재모델을 이용하는 평가 방법의 도입이 필요하다. The fire performance evaluation methods in Korea and overseas for interior finish materials were analysed and tested with gypsum board and plywood by using room corner test not adopted by domestic code until now. The results of gypsum board (thickness: 8 mm) and plywood (thickness: 4 mm) applying NFPA 265 and ISO 9705 test respectively are satisfied the assessment criteria. To assess a actual fire performance and classify fore hazard levels for interior finish materials, room-corner test and flame spread models should be adopted in building code and fire code to overcome limitations of current bench-scale test method. Keywords : Fire performance evaluation, Room corner test, Gypsum board, Plywood

씨름선수에서 체중 감량과 회복기의 Leptin과 PAI-1 변화

김용운,도경오,권태동,박덕일,장응찬,박소영,김종연,이석강 대한스포츠의학회 2000 대한스포츠의학회지 Vol.18 No.2

Obesity which is defined as accumulation of excess body fat, is central factor of insulin resistance syndrome. Recently, it is revealed tat adipose tissue is not simply an energy storage organ but it also secretes a variety of molecules which affect the metabolism of the whole body, those are leptin and plasminogen activator inhibitor-1(PAI-1). Therefore, leptin and PAI-1 are increased in the obese state. Leptin regulates energy homeostasis and satiety and PAI-1 regulates fibrinolytic system. For these reasons, elevated levels of leptin and PAI-1 are considered as link factors between obesity and insulin resistance syndrome. However, the exact regulating mechanism for serum levels of leptin and PAI-1 is not fully understood yet. In this study, to evaluate the regulating mechanisms of serum levels of leptin and PAI-1 according to the weight changes, we measured leptin, PAI-1, physical, metabolic, and endocrine parameters during 10 days of weight reduction and 10 days of regain period in 7 young athletes. The mean body weight change was -4.7 kg(5.0%) in the weight reduction period and -2.4 kg(2.5%) in the weight regain period compared to baseline value. Baseline level of leptin in athletes was 1.7±0.66 ng/ml, which was significantly correlated with body weight, BMI, percent body fat, body fat mass, triglyceride, insulin, and PAI-1. Baseline level of PAI-1 in athletes was 16.6±5.26 ng/ml, which was significantly correlated with body weight, BMI, triglyceride, insulin, and leptin. Leptin was decreased to 0.7±0.39(44% of the basaline value) in the weight reduction period, and increased to 1.9±0.64(119% of the baseline value) in the regain period. PAI-1 was decreased to 7.4±2.72(44% of the basaline value) in the weight reduction period, and increased to 22.8±7.33(138% of the baseline value) in the regain period. The changes of leptin during weight reduction period were significantly correlated with the changes of insulin(r=0.890, P<0.01) and triglycerides(r=0.874, P<0.01). The changes of PAI-1 during weight reduction period were significantly correlated with the changes of FFA(r=0.889, P<0.01) and triglycerides(r=0.869, P<0.05). The changes of both leptin and AAI-1 during weight regain period were significantly correlated with the changes of insulin(r=0.755 and 0.849, P<0.05, respectively). In summary, these results suggest that serum levels of leptin and PAI-1 were affected by weight cycling, the percentages of change were more greater than that of weight change, and rebound phenomena were occurred during weight regain period.

유방 침윤성 관암종의 CD44 발현도와 예후 인자들과의 관계

김정완,곽정식,손윤경,이승철,정운복 경북대학교 병원 1998 경북대학교병원의학연구소논문집 Vol.2 No.1

CD44 is a family of transmembrane glycoproteins involved in cell-cell and cell-matrix interactions. Expression of CD44 isoforms (splice variants) has been shown to be associated with poor prognosis in several human cancers. We evaluated the expression patterns of the CD44 isoform (CD 44 splice variant v6) in infiltrating ductal carcinoma of the breast by immunohistochemical and RT-PCR method. Paraffin embedded blocks from seventy-five cases of mastectomized samples were analyzed immunohistochemically using monoclonoal antibody against CD44v6. CD44v6 was detected in fifty-seven cases(76%) of the tumor samples. Adjacent normal myoepithelial cells and ductal epithelial cells revealed focal positive reaction to CD44v6. Thirty-two cases (80.0%) withe lymph nodal metastasis revealed overexpression of CD44v6 monoclonal antibody, but twenty-five cases (71.4%) without nodal metastasis also showed positive reaction to CD44v6 monclonal antibody, and there is no statisticallly significant value. Other prognostic factors of infiltrating ductal carcinoma, such as tumor size, histologic grade and hormonal receptors did not show any significant correlation with CD44v6 expression. The RT-PCR studies for 9 cases of infiltrating ductal carcinoma showed the same band patterns both in the normal and tumor tissues. From the above results, it is concluded that the expression of CD44v6 is not a valuable prognostic marker of infiltrating ductal carcinoma of breast.(Korean J Pathol 1997;31: 635~643)
