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.

Background: From many previous studies, Pulmonary hypertension is the known independent predictive factor of the mortality in COPD. Also pulmonary hypertension is the major cardiovascular complication of COPD and is associated with the progression to cor pulmonale and poor prognosis. Author want to analyze the correlation between pulmonary hypertension and the severity of COPD which are classified by forced expiratory volume in one second, and the extent of progression to corpulmonale. Methods: Retrospectively we investigated the medical records of 118 patients with COPD who had pulmonary function test and echocardiogaphy more than one times during one-year follow-up (from June, 2005 to May, 2006) at respiratory division in chosun university hospital, and then 50 patients were enrolled in this study. We classified the severity from FEVl in pulmonary function test based on the GOLD guideline, also this was comparably analyzed with RVSP, RVIDd, Visual Grading from echocardiography. Results: 16 patients out of 50 were classified as moderate severity, 25 patients were severe, and 9 patients were very severe group. RVSP was higher in more severe groups than less severe groups but when it comes to pulmonary hypertension that RVSP is over 35 mmHg, there was no valid difference lies in those groups. As FEVl decreases RVSP and RVIDd increases, and observed relationship between RVSP which was classified as below 35 mm and above 35 mm groups and visual grading which was classified as normal and dilatated groups revealed valid correlation, Conclusion: As pulmonary function decreases, progression to pulmonary hypertension and cor pulmonale increases but there was no remarkable difference of prevalence in above moderate severity groups. 연구배경 폐고혈압은 이전의 많은 연구에서 만성폐쇄성폐질환에서 독립적인 사망의 예측인자로 알려져 있다. 또한 폐고혈압은 만성폐쇄성폐질환의 주요한 심혈관계 합병증이며, 폐성심으로의 진행 및 불량한 예후와도 관련되어 있다. 이에 저자는 폐고혈압과 1초간 노력성호기량으로 분류되는 만성폐쇄성폐질환의 중증도 및 폐성심으로의 진행 정도를 비교 분석하여 이들의 상관관계를 밝혀보고자 한다. 방법 2005년 6월부터 2006년 5월까지 1년 동안 본 병원 호흡기 내과에서 폐기능검사와 심장초음파 검사를 각각 1회 이상 시행한 적이 있는 118명에 한하여 의무기록을 후향적으로 조사하여 이 중에서 50명을 대상으로 하였다. 폐기능검사 시행 결과 얻은 1초간 노력성호기량을 바탕으로 GOLD guideline에 따라 중증도를 분류하였으며 이를 심초음파 시행 결과 얻은 우심실수축기압, 확장기말 우심실내부간격, 시각등급과 비교분석하였다. 결과 대상 환자 50명중 16명은 중등증, 25명은 중증, 9명은 최고중증 그룹으로 분류되었다. 우심실수축기압은 중증도가 높은 그룹에서 낮은 그룹에 비해 더 높게 나타났으나 폐고혈압에 해당하는 우심실수축기압이 35 mmHg이상인 환자에 있어사는 각 그룹간에 유의한 차이를 보이지 않았으며, 확장기말 우심실내부간격, 시각등급 또한 중증도와 유의한 차이를 보이지 안항ㅆ다. 1초간 노력성호기량이 감소함에 따라서는 우심실수축기압, 시각등급은 증가하였으며 우심실수축기압을 35mmHg 미만과 이상인 그룹으로, 시각등급을 정상과 확장이 있는 그룹으로 분류하여 비교한 결과에서는 유의한 상관관계를 나타냈다. 결론 폐기능이 감소할수록 페고혈압 및 폐성심으로의 진행이 증가하였으나 폐기능검사에서 중등도 이상의 그룹에서 유병률의 차이는 크지 않았다.

목 적 : 본 연구는 직업성 연 폭로근로자에서 연폭로가 남성 생식기계 독성중 성호르몬에 미치는 영향과 그 정도를 평가하고자 시도되었다.방 법 1998년 하반기에 실시한 일반, 특수건강진단자중 경기도 지역 직업성 연 폭로 근로자 33명과 과거 직업력에서 연 폭로가 없었던 사무직 근로자 33명을 연구대상으로 선정하였다. 연의 생물학적지표로는 혈색소, ZPP, 혈중 연, 및 요중 연을 이용하였으며, 성호르몬으로는 LH, FSH, testos-terone, SHBG 및 FTI를 이용하였다. 연 폭로 지표와 성호르몬과의 상관관계를 조사하였다. 결 과 : 연의 생물학적 지표중 혈색소는 폭로군에서 대조군보다 유의하게 낮았으며, ZPP, 혈중 연및 요중 연등은 폭로군에서 대조군보다 유의하게 높았다. 성호르몬에서 FSH, testosterone, SHBG및 FTI는 모두 폭로군에서 대조군보다 낮았으나 통계적 유의성은 없었다. 폭로군의 성호르몬중에서 연령은 FSH 및 FTI, ZPP는 FSH, 혈중 연은testosterone과 유의한 상관관계가 있었다. 대조군에서 연령은 FSH, testosterone, SHBG 및 FTI와 흡연량은 FSH와 유의한 상관관계가 있었다. 연령군별 폭로군과 대조군의 성호르몬 비교에서 30-39세군의 FTI에서 폭로군이 대조군보다 유의하게 낮았으며 그 밖의 호르몬에서는 모두 유의한 차이가 없었다. 결 론 : 연 폭로군의 FSH, Testosterone, SHBG 및 FTI가 대조군에 비교하여 낮았으나 통계적 유의성은 없었다. 그러나 폭로군에서 연의 생물학적 지표와 일부 성호르몬간에 유의한 상관관계를보였으며 이는 본 연구 대상 근로자의 연 폭로 수준이 일부 성호르몬에 영향이 있음을 보여주는 것으로 판단된다. 향후 이에 대한 지속적인 연구가 진행되어 야 할 것이다. Objectives : This study was performed to evaluate the relationship between biological markers of lead exposure and level of sex. hormones in men occupationally exposed to lead. Methods : In this study, 33 male workers who employed at smelting and battery factories were compared with 33 male workers who were not exposed to lead. As biological markers of lead exposure, hemoglobin, ZPP, blood lead and urine lead were measured. As sex hormones, FSH, LH, testosterone, SHBG and FTI were determined. Results : Hemoglobin level was significantly lower in exposed than in nonexposed group. Level of ZPP, blood lead, and urine lead were significantly higher in exposed than in nonexposed group. There was a trend that level of FSH, testosterone, SHBG, and FTI was lower in exposed than in nonexposed group respectively, but there were no statistical significance. In exposed group, FSH level was correlated with age, ZPP, and blood lead; testosterone level was correlated with hemoglobin, blood lead, urine lead, and SHBG ; and FTI level was correlated with age. Conclusions : Level of some sex hormones were lower in exposed than in nonexposed group but there were no statistical significance between the exposed and the nonexposed group. But level of sex hormones were correlated with several biological markers of lead in exposed group. It suggests that occupational lead exposure might affect sex hormones.

카드뮴 첨가된 α형 산화철에 의한 일산화탄소의 촉매산화 반응연구

이성한,김용록,김돈,정원양,김규홍,최재시 연세대학교 자연과학연구소 1983 學術論文集 Vol.11 No.-

α형 산화철에 카드뮴을 4mol%, 8mol% 및 12mol%로 각각 첨가시켜 외성영역의 특성을 갖는 산화물들을 제조하였다. 이 산화물들을 촉매로한 일산화탄소의 산화반응 속도론적 연구를 통하여 본산화물의 결함구조, CO 산화반응에 대한 촉매성 및 불순물 첨가효과등을 조사하였다. 또한 450℃에서 O_2 및 CO를 여러압력으로 도입시켜 Cd-doped α-Fe_2O_3의 전기전도도를 측정하고 이를 반응속도론적 데이타와 결부시켜 본산화물상에서 CO 의 산화반응 메카니즘과 율속단계를 제안하였다. 반응온도범위 350~460℃에서 산출된 활성화에너지는 10.1~11.3kcal.mol^-1이었다. CO_2흡착에 의한 CO산화반응의 억제효과는 본실험의 반응온도 영역인 350~460℃에서는 나타나지 않았으며 CO 산화반응의 전반응속도 차수는 1.5차로서 일산화탄소에 대해서는 1차, 산소에 대해서는 0.5차임이 밝혀졌다. 반응속도론적 데이타와 전기전도도 데이타에 의해 본촉매의 활성은 카드뮴도프로 인해 생성된 산소공위(Vo"-2e^-)에 기인한 것이었다. 카드뮴의 첨가량이 증가할수록 반응속도는 증가하였으나 12mol% 이상의 카드뮴이 첨가된 산화철상에서는 반응속도가 크게 증가하지 않는 것으로 나타났다. CO와 O_2는 근본적으로 화학흡착하며 CO의 흡착자리는 격자산소(O^-2_(latt))와 기흡착원산소 (O^-_(ads)), 그리고 O_2의 흡착자리는 산소공위(Vo"-2e^-)로 밝혀졌다. The α-Ferric oxide containing 4, 8, and 12mol% with cadmium were prepared. The oxidation rates of carbon monoxide in the presence of these oxide systems were measured to investigate the defect structure, the catalytic activity for the oxidation of carbon monoxide, and the impurity effect. The conductivity was also measured at 450℃ under the various pressures of oxygen and carbon monoxide. From the agreement between the kinetic and conductivity data, the oxidation mechanism of carbon monoxide and the rate determining step on this oxide catalyst were suggested. In the temperature range from 350 to 460℃, the calculated activation energy for the CO oxidation over Cd-doped α-Fe_2O_3 systems were 10.1∼11.3kcal·mol^-1. The inhibition by an adsorbed CO_2 during the CO oxidation was not observed in the above temperature range. The overall reaction order for the CO oxidation is 1.5; the first order with respect to CO and the one-half order with respect to O_2. The catalytic activity of this oxide system is due to oxygen vacancies induced by Cd-doping. The oxidation rates increase with increasing the amount of dopant and above 12mol%, however, don't highly increased. CO and O_2 are essentially chemisorbed as ions and the adsorption sites for CO are the lattice oxygens (O^2-_(latt)) and prechemisorbed oxygens (O^-_(ads)), the adsorption site for O_2 is the oxygen vacancies (Vo¨-2e^-).
