        원종호,박성규,홍대식,박희숙,김은석,최두호 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.1

        Purpose : Patients with cancer of unknown primary site represent 5% to 10% of all cancer patients. This study was to evaluate survival and prognostic factors of patients with malignancy of unknown origin. Materials and Methods : A retrospective analysis was done for one hundred and two patients with malignancy of unknown origin who were treated from January 1989 to December 1998. There were 52 male and 50 female patients. Age of patients ranged from 20 to 94 years (mean 58 years). Clinical presentation depended on the site of metastases. In cases of multiple metastatic sites, we selected the first apparent metastasis or the symptomatic one for which the patient was first seen. The three most frequent initial metastatic sites were peritoneum, lymph node, and liver. Median follow up period was 4 months(0-100 months) and survival rate measured form the time of diagnosis. Results : The two years survival rate was 13.6% with a median survival time of 4 months. The factors associated with the overall survival rate were the tumor marker CEA(p=0.0061), smoking history(p=0.0039), and histologic type(squamous cell carcinoma versus non-squamous cell carcinoma, p=0.0295). Marginal statistical difference was found according to performance status. No statistical differences were found according to sex, weight loss, initial metastatic site and numbers, primary lesion site, and treatment modality. Conclusion : Squamous cell carcinoma was associated with survival rate. In squamous cell carcinoma of unknown origin with good prognostic factor, especially cervical lymph node metastasis, we suggest an approach of extensive initial workup for staging and aggressive treatment.

        구대서,박성원 한국비파괴검사학회 2002 한국비파괴검사학회지 Vol.22 No.1

        수중에서 사용후 핵연료 제원측정 시험의 효율성을 높이고 측정오차를 줄이기 위하여 수중 영상측정방법을 개발하였다. 이 시스템의 모의 핵연료봉 직경 및 측정치는 실제값 기준으로 할 때, 각각 -0.24±0.03mm, 0.34±0.06mm이고 측정 최대오차는 각각 -0.3mm 및 0.4mm 이내였다. 실제 사용후핵연료에 대한 수중 제원측정결과 고리원자력 2호기에서 2주기 동안 연소한 핵연료 집합체 J44의 핵연료봉 직경은 설계치 기준으로 할 때 핵연료봉 상ㆍ하단부 직경은 2.0%, 중앙부의 직경은 3.0% 정도 감소하였으나 핵연료봉의 길이는 0.4% 정도 신장하였다. 고리원자력 1호기에서 3주기 동안 연소한 핵연료 집합체 F02 의 핵연료봉의 직경 및 길이는 핵연료 집합체 J44의 결과와 비슷한 경향을 나타내었다. A pool image processing measurement method has been developed to improve the examination efficiency and to minimize the errors of dimensional measurements of spent fuel assemblies in pool. Diameter and length measurements of mock-up fuel rods using the image processing system are 0.24±0.03mm, 0.34±0.06mm on the basis of the true value and their maximum errors are within -0.3 and 0.4mm, respectively. According to the result of dimensional measurement of spent fuels in pool, the upper and lower part diameter and mid part diameter of fuel rods of the J44 fuel assembly irradiated for 2 cycles in the Kori-2 nuclear reactor were decreased by about 2.0 and 3.0% in comparison with design values, respectively. The length of fuel rods was elongated by about 0.4%. The change behavior of diameter and length of fuel rods of the F02 fuel assembly irradiated for 3 cycles in the Kori-1 nuclear reactor showed a trend similar to the results of J44.

        한대희,김성구,박상호,김성한,조원영,방덕원,조윤행,정의룡,은영근,권영구 순천향의학연구소 2003 Journal of Soonchunhyang Medical Science Vol.9 No.1

        Background : Patients with chronic renal fialure have a substantially elevated risk of death from cardiovascular diseases than do the general population. the patients with chronic renal failure are at significantly increased freqeuncy of hypertension, hyperlipidemia, and diabetes mellitus which are known to the risk factors of the coronary artery diseases, and the prevalence of the coronary artery diseases in chronic renal failure patients is highly associated with the hemodynamic disorder and metabolic abnormalities. therefore we expected that the coronary angiographic findings in patients with chronic renal failure should be different from the general population (control groups) and investigated the risk factors contributing to coronary artery diseases. Method : we have retrospectively compared the coronary angiographic findings of 44 patients with chronic renal failure on hemodialysis with that of 88 patients in the general population and investigated the factors contributing to the development and acceleration of coronary artery diseases in patients with chronic renal failure Result : Hypertension and diabetes mellitus which is risk factors for coronary artery disease is significantly increased in patients with chronic renal failure, in coronary angiographic finding the severity of the lesion is worse. the incidence of PCI or CABG of patients with chronic renal failure is more than that of control group but statistically no difference between patients with chronic renal failure and control group. the sex, the duration of disease, the duration of dialysis, serum creatinine in patients with chronic renal failure have no correlation to the prevalence of coronary artery disease and severity of lesion. hyperglycemic patients with chronic renal failure have high incidence of coronary artery disease and are worse in the severity of lesion Conclusions : There is significantly increased the pevalence and severity of involving multiple coronary artery diseses in hyperglycemic patients with CRF.

      • 허혈성 심질환에 있어서 아데노신 급속 정맥투여후 관동맥압의 변화에 관한 연구

        봉종대,오종용,배성한,신원용,김철현,이광희,최태명,현민수,김성구,권영주 순천향의학연구소 1998 Journal of Soonchunhyang Medical Science Vol.4 No.2

        Background: Adenosine interacts with A1 receptors present on the extracellular surface of cardiac cells, activating K+channels in a fashion. It produces coronary vasodilatation and AV nodal block. The half-time is one to six second and has ultra-short action. In ischemic heart disease, fractional flow reserve(FFR) can be achieved safely with intravenous adenosine infusions at a rate of 150㎍/kg/min which cause maximal coronary hyperemia. Purpose: We investigated the patients who have had ischemic heart disease(n=8). After adenosine intravenous administration(150㎍/kg/min), the effect cause maximal hyperemia of coronary artery. During peak maximal hyperemia, we reported clinical findings, coronary hemodynamics and electrocardiogram findings. Methods: After diagnostic coronary angiography and left ventriculography, catheter was advanced into the ostium of coronary artery. We investigated coronary hemodynamics such as systolic coronary artery pressure, diastolic coronary artery pressure, mean coronary artery pressure and heart rate. To assess the use of adenosine for determination of fractional flow reserve, hemodynamics and electrocardiogram were measured at basal state and during peak maximal hyperemia. Results: Symptoms developed 1.5-2 minute after adenosine intravenous administration and each symptom disappeared 2-2.5 minute after adenosine administration. Two patients represented asymptomatic appearance and six patients complained of flushing, chest pain, palpitation and headache. In eight patients with ischemic heart disease, 1.5 minute after venous administration of 150㎍/kg/min of adenosine, coronary artery pressure decreased and heart rate increased significantly. Conduction abnormalities after administration of 150㎍/kg/min of adenosine were transient 2nd degree AV block 2 cases(25%). Conclusions: Adenosine is a potent ultra short-acting vasodilator. Although coronary artery pressure decreased and heart rate increased and mild cardiovascular symptoms occurred after continuous infusion of 150㎍/kg/min of adenosine, it is useful as an agent for determination of fractional flow reserve.

        최석구,김현대,정태기,김대현,김용복,유원상 인제대학교 1994 仁濟醫學 Vol.15 No.2

        만성 심부전 환자에게 새로운 경구용 비 digitalis 강심제인 denopamine 1T(5mg)을 1일 3회 3개월간 투여하여 그 유효성 및 안전성을 검토했다. Background : Patients with congestive heart failure have a high mortality rate and are also hospitalized frequently. We studied the effects of a new oral inotrophic agent, denopamine in patients with chronic heart failure. Methods : 16 patients receiving conventional treatments for heart failure were treat ed with denopamine 5mg tad for at shortest 3 months. Their history were taken and the physical examination, general laboratory test and the echocardiographic examination were done before and after treatment. Results: There were 3 deaths and 1 withdrawal because of worsening heart failure. 5 patients (42%) among 12 patients showed the improvement in their subjective symptoms. The fractional shortening and ejection fraction of the left ventricle were increased by 3.2% and 5.6% respectively in their absolute values. Conclusion : The addition of denopamine to conventional therapy considerably improved the subjective symptoms and the left ventricular function in the limited number of patients with chronic heart failure.

      • 만성 심부전환자의 혈액에서 측정한 Tumor necrosis factor-α 및 Interleukin-6의 임상적 의의

        김명구,김성구,박상호,한대희,강진환,변정득,심규혁,최병조,방덕원,온영근,현민수,권영주 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.2

        Background and objectives: Many conditions are responsible for the pathophysiology and progressive mechanisms of congestive heart failure. More recently, it has also become evidence that another class of biologycally activated molecules generically reffered to as cytokine these are also over expressed in congestive heart failure. Therefore, the purpose of this study was to measure concentrations of tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) in mild to severe symptoms of heart failure and compare their values with those found in normal control and analysed correlation relationship between cytokine level, clinical findings and hemodynamic indicies. Subjects and Methodology: Levels of TNF-α and IL-6 were measured on pulmonary artery during cardiac catheterization in heart failure patients(n=32) and normal subjects(n=8) as well as physical examination and echocardiogram. Cytokines assay were performed on plasma using commercially available ELISA(Enazyme-Linked Immunosorbent Assay) kits. Results: Although the levels of TNF-α and IL-6 tend to increase in congestive heart failure group, the cytokines level was not made significantly statistical difference between congestive heart failure group and controls. When analyzing the correlation between the levels of PCWP(pulmonary capillary wedge pressure) and cytokines(TNF-α, IL-6), respectively, there were statistically significant correlation coefficient 0.32,(p<0.05), 0.39(p<0.01). The cytokine IL-6 and pressure of pulmonary artery were significant correlation.(correlation coefficient 0.36, p<0.02) More significantly, there was correlated with TNF-α and IL-6.(correlation coefficient 0.57, p<0.001) Conclusions: There was tended toward high concentration of TNF-α & IL-6 in congestive heart failure and significant difference for PCWP between TNF-α & IL-6, thus may be correlated with development and progression in congestive heart failure.

        정태기,김현대,류재춘,최석구,유원상 인제대학교 1993 仁濟醫學 Vol.14 No.4

        Prostaglandin 합성을 촉진하는 새로운 강압약인 cicletanine의 강압효과를 진료실 혈압과 24시간 활동혈압으로 평가했을 때 상당한 차이를 보여 그 이유를 검토해 보았다. To evaluate antihypertensive effect of cicletanine with both clinic and ambulatory blood pressure monitoring, 10 male hypertensive patients were administered cicletanine, a new antihypertensive stimulating prostaglandin synthesis, in 100∼200 mg daily for 12 weeks. The following were the results. 1.Mean of clinic BP decreased from 161/98 mmHg to 153/98 mmHg. 2.Mean of ambulatory BP changed from 140/91 mmHg to 153/99 mmHg. 3.Side reactions were mild, namely indigestion and constipation. 4.Discrepancy between clinic and ambulatory BP were discussed. In conclusion cicletanine revealed slight antihypertensive effect with clinic blood pressure, but failed to confirm it with ambulatory blood pressure.

        H. pylori 제균으로 완전 관해된 위의 고도 MALT 림프종 1예 : a case report

        황창연,류민희,강윤구,김태원,장흥문,엄대운,허주령 대한내과학회 2004 대한내과학회지 Vol.66 No.1

        위의 저도 MALT 림프종은 H. pylori 제균 후에 60∼90%가 관해를 보이는 것으로 알려져 있으나 고도 MALT 림프종은 H. pylori 제균 만으로는 치료가 부족한 것으로 알려져 있다. 그러나 최근에 위의 고도 MALT 림프종에서도 H. pylori 제균 치료를 통해 관해에 이른 사례들이 보고 되었고, 저자들도 고도 MALT 림프종 환자에서 H. pylori 제균 치료를 통하여 내시경적 및 조직학적 완전 관해에 도달한 증례를 경험하여 이를 보고하는 바이다. Low grade MALT lymphoma of stomach is associated with H. pylori infection in more than 90% of cases, and eradication of H. pylori leads to regression of the low grade MALT lymphoma in 60∼90% of cases. On the contrary, high grade MALT lymphoma is thought to be independent from H. pylori for growth and usually is thought to require antitumor chemotherapy. However, there have been recent reports of high grade MALT lymphoma regressing after H. pylori eradication. We experienced and are reporting a case of high grade MALT lymphoma arising in the background of low grade MALT lymphoma that showed complete regression after H. pylori eradication.
