단백질분해효소를 생성분비하는 호알칼리성 Coryneform bacterium TU-19의 분리 및 동정

최명철,양재섭,강선철 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

토양으로부터 알칼리성 단백질분해효소를 생성분비하는 호알칼리성 미생물을 분리하였다. 이 균의 형태적 특징은 Gram 양성이었으며, 포자를 형성하지 않고, 운동성이 없으며, 불규칙적인 간균의 형태를 하고 있는 호기성 미생물이었다. 또한 기타 다른 형태적, 생리생화확적 특징과 종합적으로 비교해 볼 때 이 균주는 Coryneform 세균과 매우 유사하였다. 따라서 본 분리균주는 Coryneform bacterium TU-19로 잠정적으로 동정하였다. 그러나 화학적 분석 결과 및 부분적인 생리생화적 특징들에 있어서는 Coryneform bacteria의 어느 종과도 정확히 일치하지 않았다. An alkalophilic bacterium producing alkaline protease(s) was isolated from soil. It was a Gram-positive, non-sporulating, immotile, irregular rod, strictly aerobic, and weak acid-forming bacterium. The morphological, physiological, and biochemical characteristics of the isolate resembled those of the Coryneform bacteria. However, there was not any species within this genera to which microorganism can be closely matched. Therefore, it is provisionally identified as a Coryneform bacterium TU-19.

도심지 하수관거의 I/I 및 CSOs 특성

김병욱,최승철,원철희,임재명 강원대학교 부설 석재복합신소재 제품연구센터 2003 석재연 논문집 Vol.8 No.-

본 연구에서는 도심지 하수관거의 특성을 파악하기 위하여 원주시를 대상으로 수질 및 유량 조사를 통하여 기존 하수관거의 침입수/유입수(I/I) 분석 및 하수관거 정비사업시 우선순위 결정을 위한 자료제공과 강우시 CSOs의 발생특성을 분석, 결과를 고찰하였다. 그 결과 원주시의 조사지점별 평균 BOD는 원주하수종말 처리장 설계기준과 비교하여볼 때 26.O~60.7%로 매우 낮게 배출되는 것으로 조사되었으며, 평가기법에 의한 원주시 도심지역의 I/I율은 평균하수량의 35.7~74.6%로 매우 높은 것으로 조사되었다. 또한, 강우시 발생하는 CSOs는 배수유역의 크기와 강우량, 강우강도, 차집용량에 따라 큰 유량차이를 보였으며, CSOs의 수질분석결과 강우초반부 초기세척(First-flush)현상으로 수질이 급격히 상승하였다가 감소하는 것으로 나타났으며, CSOs의 BOD부하를 살펴보면 일평균 BOD부하의 18.7~38.5%이상으로 인근수역으로 미처리되어 배출되는 것으로 조사되었다. 이와같이 하수관거의 I/I율과 CSOs의 발생특성은 조사지점의 특성에 따라 큰 차이가 있으므로 관거정비사업시 이에 대한 충분한 조사 및 분석이 이루어져야 할 것이다. Infiltration/Inflow(I/I) is the major deterrent to the successful performance of the sewer and the treatment systems. An excessive I/I in a sanitary sewer system can hydraulically overload the sewer lines and the wastewater treatment plants and combined sewer overflows(CSOs) are untreated wastewater during storm events. The characteristics of the CSOs are extremely variable, depending upon local physical conditions such as topography, soil conditions, degree of development and imperviousness of surface. As a result of the flow rate and water quality monitoring, biochemical oxygen demand(BOD) concentration was significantly low as 26.0-60.7% of 173mg/L which is a design standard of wastewater treatment plant. I/I rate of sewer in the center of Wonju city evaluated by assessment method was very high as 35.7-74.6% of total flow. Furthermore, 18.7-385% of BOD load of CSOs during wet weather was discharged into watershed with being untreated. As stated above, I/I running into sewer system should be considered before everything when sewer system is improved and CSOs generated during wet weather should be necessarily deliberated for design of water treatment plant and improvement of sewer system.

이광희,김철현,최태명,이성우,김성구,권영주,변재호 순천향의학연구소 1996 Journal of Soonchunhyang Medical Science Vol.2 No.1

특발성 확장성 심근증에 대한 진단 및 연구는 이전에 주로 관혈적인 좌심실조영술이나 부검에 의해 이루어져 연구가 많이 않았으나 최근 심초음파도의 보편적인 이용으로 진단이 용이하여 이에 대한 임상적 연구가 증가되고 있다. 그러나 남녀 성별에 따른 임상적 소견의 차이에 대한보고는 많지 않았다. 대상 및 방법 : 특발성 확장성 심근증으로 진단받은 환자 68명(남자 37명, 여자 31명)을 대상으로 임상적 소견과 심전도 및 심초음파 검사소견등을 남녀간에 비교 분석하였다. 결 과 1. 유병기간은 여자가 남자보다 유의하게 길었고(p<0.05), 호흡곤란, 심계항진 및 심부전의 빈도는 여자에서 더 많은 경향을 보였으나 통계적으로 유의한 차이는 없었다. 2. 심초음파도상 좌심실 이완기말 내경계수, 심실중격 두께 계수, 좌심실 후벽 계수, 좌심방 내경 계수는 여자가 남자보다 유의하게 컸으나(p<0.01), 분획단축(fractional shorting)은 양군간에 유의한 차이가 없었다. 3. 심전도상 QRS 기간이 여자가 남자보다 긴 경향이 있었으나(p<0.08) 기타 소견은 양군간에 유의한 차이가 없었다. 결 론 : 특별성 확장성 심근증의 임상적 소견 및 검사 소견의 성별에 따른 분석에서 여자에서 질병의 정도가 더 심한 것으로 나타나는 소견이 있었으나 추후에 더 많은 연구및 원인 분석이 필요할 것으로 사료된다. Background : Idiopathic dilated cardiomyopathy(IDC) is a well recognized condition both clinically and morphologically. Despite the relatively frequency of this condition, few studies focusing on sex difference have been reported. Method : A total of 68 patients with IDC(37 men, 31 women)were studied retrospectively. Certain clinical and laboratory findings were analyzed and compared between men and women. Results 1. The women had a significantly(p<0.05) longer mean duration of chronic congestive heart failure than men. 2. Of the echocardiographic findings, index of left ventricular end-diastolic diameter, interventricular septal thickness, left ventricular posterior wall thicknes and left atrial dimension were significantly higher in women than in men. 3. Duration of QRS complex in ECG was longer in women(p<0.08) conclusion Some of clinical and laboratory findins are more advanced phase in women in IDC.

김명수,김성구,정호석,온영근,신원용,김철현,최태명,현민수,권영주 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.1

Background and aims : The clinical syndrome unstable angina pectoris that encompasses a variety of symptoms and clincal presentations of transient episode of myocardial ischemia, was devided to several subgroups. Also, it has variable pathophysiologic factors to cause myocardial ischemia. According to clincal presentation, coronary angiographic finding and prognostic factor, the result of unstable angina pectoris is variable. In fact, there were a few data reported on the prognosis of wide spectrum of patients with unstable angina. However, the precise risk of subgroups according to classitication has not been established because it was difficult to compare between studies. We classified unstable angina pectoris by clinical nature of chest pain, and performed to establish and compare the clinical presentations, coronary angiographic findings, treatement and prognosis of patients with unstable angina within subgroups of classification. Methods : Retrospenctive data for 164 unstable angina pectoris patients admitted to the Internal Cardiology Division of Soon Chun Hyang University Hospital from May 1996 to July 1999 was analyzed. The patients were classified into one of the following categories: Class I, new onset of severe angina; Class II, acceleration of previous chronic stable angina; Class III, angina at rest. Clinical presentations, echocardiographic findings, coronary angiographic findings, treatment and prognosis were compared. Results : From the total 164 patients, the subjects of classes were as follows : Class I, 46 cases (28.1%); Class II, 74 cases (45.1%); Class III, 44 cases (26.8%). In view of age distribution, the 7th decade had the highest incidence, and then, 6th, 8th decades were followed. There was no baseline differences among the 3 classes with respect to gender, number of risk factors. Significantly, class II showed more severe findings in abnormal Q wave 15 cases (20.8%), total occclusive lesion 10 cases (20.8%) and three vessel coronary disease 11 cases (22.9%) than other classes. The change of ST segment was significantly apparent (p<0.02) among class I 28 cases (60.8%), class III 26 cases (59.0%), comparing with class II 30 cases (40.5%). Class III had the higher incidence of one vessel coronary artery disease than class I and III. The heparin treatment was performed in 99 cases (60.1%). The incidence of nonfatal myocardial infarction was much more in class I and III, each 4 cases (8.7%, 9.8%) than in class II 1 cases (1.4%). In-Hospital death was occurred in class I and II, each 1 case. Conclusion : The patients with the acclerated angina from chronic stable angina had more severe coronary artery disease than other classes, but they had better in-hospital prognosis.

Background: Limited studies have been identifi ed about nursing and healthcare-associated pneumonia (NHCAP) requiring intensive care unit (ICU) admission. We evaluated the clinical and microbiological characteristics of NHCAP patients admitted to the ICU. Methods: NHCAP was categorized as four groups. Reviewed database included age, gender, comorbid diseases, laboratory data and microbiological Results: The severity of pneumonia was assessed by using the pneumonia severity index (PSI) and CURB-65. The 30-day mortality and duration of ICU stay were evaluated as endpoints Results: Total 428 patients (men, 67.1%) were reviewed. The mean age was 71.2 ± 11.9 year-old. Thirty-day mortality was 25.5%, and duration of ICU stay was 13.8 ± 13.3 days. Mortality (P = 0.349) had no signifi cant difference among four groups although duration of ICU stay (P = 0.008) was signifi cantly longer in group C and D. When we performed multivariate logistic analysis using signifi cant variables, PSI score (OR 1.015 95% CI 1.004-1.026, P = 0.009), serum HCO3- level (OR 0.954 95% CI 0.918-0.993, P = 0.020), duration of ICU stay (OR 0.971 95% CI 0.950-0.993, P = 0.010), multidrug-resistant (MDR) pathogens including ESBL-producing K. pneumoniae (OR 2.688 95% CI 1.237-5.840, P = 0.013) and MDR A. baumannii (OR 3.081 95% CI 1.504-6.311, P = 0.002) were signifi cantly associated with 30-day mortality. Conclusions: ESBL-producing K. pneumoniae and MDR A. baumannii were more often isolated and associated with mortality in NHCAP in ICU patients, therefore these MDR pathogens as well as PSI score should be considered as prognostic factors in NHCAP.

Myoung-Soon Choi,Jee-Bum Lee,Seong-Jin Kim,Seung-Chul Lee,Young-Ho Won,Sook Jung Yun 대한피부과학회 2011 Annals of Dermatology Vol.23 No.-

Poikiloderma vasculare atrophicans (PVA) is a rare variant of mycosis fungoides, and is characterized by generalized hyperkeratotic scaly papules in net-like, retiform, or zebra-like patterns. A 59-year-old Korean woman presented with asymptomatic, erythematous-to-violaceous, reticulated confluent papules on the trunk and extremities. Skin lesions were initially limited to both thighs 25 years ago, and then spread slowly over her body. Histopathological examination showed band-like inflammatory infiltrations and epidermotropism consisting of mostly CD8+ lymphocytes. Based on the clinical manifestations and histological findings, the diagnosis of PVA was made. We herein report on a case of PVA, which featured a long-benign course without progression into the tumor stage over a period of 30 years. (Ann Dermatol 23(S1) S48∼S52, 2011)
