Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

아스페르길루스 심내막염은 드물지만 매우 불량한 예후를 보이는 질환이다. 최근 심장 수술, 면역 저하, 장기간의 항생제 사용, 약물 남용 및 후천성 면역 결핍증 등의 선행 요인과 연관되어 빈도가 증가하고 있는 추세이다. 국내 최초로 자연 판막에 발생한 아스페르길루스 심내막염을 심초음파 검사 및 수술 조직을 통해 진단하였고, 이에 대해 문헌 고찰과 함께 보고하는 바이다. Fungal endocarditis is a rare but poor-prognostic disease. It typically occurs in patients with several predisposing factors such as open heart surgery, long term venous catheterization, antibiotic therapy, intravenous drug abuse, hematologic malignancy and AIDS. We report a case of native endocarditis caused by Aspergillus fumigatus, which has not been reported as a causative organism of native valve endocarditis in Korea. A 47 year-old female patients without significant past medical history except pulmonary tuberculosis was admitted because of headache and neck pain. After admission, she developed high feve, new cardiac murmur and signs of multiple systemic embolization. Echocardiography revealed large mobile vegetations. Emergent mitral valve replacement was performed and Aspergillus fumigatus was isolated from the resected vegetation. Despite postoperative amphotericin B therapy, she died of subarachnoidal hemorrhage.

Mitochondria and the Nox family of NADPH oxidase are the two major sources of reactive oxygen species (ROS) that are induced by external stimuli, and the mitochondria respiratory chain is considered as an important site of ROS production within most cells. Recent evidence has demonstrated that various biological stimuli increase accumulation of unfolded or mis-folded proteins in ER lumen, which is referred to as "ER stress". Moreover, these various pathologic stimuli have been reported to provoke oxidative stress as well as ER stress. In this study, we used the mice sensitized with OVA and LPS and then challenged with OVA (OVALPS-OVA mice) for elucidation of the relationship between mitochondrial ROS and ER stress in bronchial asthma. The OVALPS-OVA mice showed that the expression of ER stress markers and the protein levels of un-folded-protein response (UPR)-related marker in lung tissues were significantly increased after OVA challenge. In addition, we visualized the localization of mitochondrial ROS in BAL cells isolated from OVALPS-OVA mice using confocal microscopy; the significant increase in mitochondrial ROS in BAL cells was observed after OVA challenge. Our results also showed that Necrox-5 or 4-PBA significantly reduced the increases in ER stress, mitochondrial ROS, inflammatory cytokines, airway in-flammation, and bronchial hyperresponsiveness. These findings suggest that mitochondrial ROS and ER stress plays an im-portant role in the induction and maintaining allergic airway diseases synergistically.

Objectives: The purpose of this study was to assess the correlation relationship between personal exposure and urinary hippuric acid in biological monitoring for airborne toluene in an industrial complex and in general environments. Methods: Personal exposure to toluene and its metabolite, hippuric acid, in urine were simultaneously measured in occupational environments area near an industrial complex and in general environments. The study subjects were divided into three types: 137 workers who use organic solvents in the workplace, 210 residents living near a dyeing industrial complex, and 379 residents living in general environments. The toluene exposures of workers and residents were measured by a passive sampler for four days. The urine of participants was sampled when the passive samplers of personal exposure were collected. Results: The toluene and hippuric acid concentrations of workers were the highest, followed by the concentrations of residents living near a dyeing industrial complex and residents living in general environments. The coefficient of correlation between the concentrations of toluene and hippuric acid among workers was 0.749 (p<0.01) in the workplace. On the contrary, correlations between the concentrations of toluene and hippuric acid among residents living near a dyeing industrial complex and residents living in general environments were all not significant. The relationship between the concentrations of hippuric acid and toluene in three types could be described by the exponential growth model. Conclusions: This study analyzed the relationships between toluene exposure and the concentrations of hippuric acid in urine in high, middle, and low exposure environments, and could be described by the exponential growth model.

목적: 석면에 노출된 근로자에서 석면관련 폐질환의 양상을 분석하고 진단에 있어 HRCT의 유용성을 연구하여 석면에 대한 의학적 감시프로그램의 개발에 기여하고자 하였다. 방법: 석면에 직접 노출되는 작업자 68명과 간접 노출되는 작업자 94명 등 총 162명에 대해 OSHA 석면 표준, 의학적 감시 프로그램에 따라 단순 흉부방사선검사, 폐활량검사 및 우리나라 실정에 맞게 일부 수정한 의학적 설문지를 통해 면접조사의 방식으로 환자에 관한 정보를 수집하였으며, 자료의 신뢰성을 확보하기 위하여 면접조사는 1달 이상의 기간을 두고 2차례에 걸쳐 실시된 후 확인, 수정하였다. 또한, 석면관련 폐질환을 확진하기 위하여 HRCT를 추가적으로 실시하였다. 결과: HRCT결과 석면관련 폐질환의 유병율은 162명의 근로자중 17명으로 10.5%였는데, 직접 노출군에서 10명 (14.7%), 간접 노출군에서 7명 (7.4%)이었다. HRCT와 비교할 때 단순 흉부방사선검사의 민감도와 특이도는 각각 70.6%와 98.6%이었고, 양성 예측도와 음성 예측도는 각각 85.7%와 96.6%으로, HRCT는 단순흉부방사선검사에 비해 민감도가 높아 초기 석면관련 폐질환을 진단하는데 효과적이었다. 석면관련 폐질환의 진단에 있어 HRCT와 폐활량검사 사이에 유의한 관련성이 관찰되었다. HRCT 결과 석면관련 폐질환의 유무와 의학적 설문조사 결과의 빈도분석을 실시한 결과, 유의한 변수는 작업기간, 흡연량, 호흡기질환의 과거력, 기침, 호흡곤란이었다. 결론: HRCT는 석면관련 폐질환의 진단에 있어 단순 흉부방사선검사와 비교하여 민감도가 높아 초기 진단에 유용하므로 단순 흉부방사선선검사 결과 석면관련 폐질환소견을 보일 때뿐만 아니라, 정상소견을 보이더라도 폐활량 검사결과와 근무력, 흡연력, 호흡기질환의 과거력, 기침, 호흡곤란 등의 호흡기 증상을 참고하여 HRCT검사를 고려해야 한다. 또한, 본 연구에서 관련성이 없었던 요인들에 대해서도 향후 연관성을 규명하는 광범위한 전향적 연구가 필요하다. Objectives: This study was carried out to improve the medical surveillance program of workers exposed to asbestos by examining the usefulness of High Resolution Computed Tomography (HRCT) in the diagnosis of asbestos-related lung disease. Methods: The study subjects comprised 162 workers in a ship-repairing yard, 68 of whom had been directly exposed to asbestos and 94 indirectly exposed. The 'Occupational Safety & Health Administration (OSHA) asbestos standard, medical surveilance program' and HRCT were conducted to analyze the aspects of the asbestos-related lung disease. The OSHA asbestos standard, medical surveilance program consists of simple chest x-ray, spirometry and medical questionnarie. Results: Seventeen (10.5%) of the 162 subjects, 10 (14.7%) directly exposed and 7 (7.4%) indirectly exposed, revealed asbestos-related lung disease on HRCT. The sensitivity and specificity of simple chest x-ray for asbestos-related lung disease were 70.6% and 98.6%, and the positive and negative predictive values were 85.7% and 96.6% respectively, as compared with HRCT, HRCT was an effective diagnostic tool especially to detect early asbestos-related lung disease. The study results indicated a relative significant association between the results of spirometry and HRCT. The variables significantly associated with asbestos-related lung disease on HRCT were work duration, smoking history (pack-years), past history of respiratory disease, cough and dyspnea. Conclusions: In the diagnosis of asbestos-related lung disease, HRCT should be considered not only for workers with positive findings on simple chest x-ray, but also workers with specific findings on spirometry, occupational history, smoking history, and past history of respiratory disease, or with respiratory symptoms such as cough and dyspnea.

Unilateral pulmonary vein atresia is a rare congenital disease and is frequently associated with intracardiac anomalies. It is usually diagnosed in childhood and is very rarely diagnosed in adulthood. A case of unilateral pulmonary vein atresia in a 20-year old female is de- scribed. The relevant findings were symptoms of exertional dyspnea, roentgenographic evidence of decreased lung volume, increased interstitial infiltration with septal lines in the involved side (right), and aoscence of blood flow in a radionuclide perfusion scan. Pulmonary angiography showed an extremely small right pulmonary artery and thining of the peripheral branches, and nonvisualization of the draining pulmonary veins. Bronchial arteriography showed rommunication between the bronchial artery and the right pulmonary artery and it was drained to the left pulmonary artery. Cardiac catheterization showed no intracardiac anomaly. The right bronchography was normal; pulmonary function studies showed a pure restrictive pattern and markedly in creased physiologic dead space. MRI showed no visible right pulmonary vein.

The quality characteristics of the bread prepared with black soybean powder(BSP) were evaluated. Breads were prepared by the addition of 0, 5, 10, 15, and 20% of BSP to the basic formulation. The pH's of dough with BSP were ranged from 5.13 to 5.77 and that of the control was 5.43. The volume of dough, loaf volume and loaf volume index of the bread with 5%-BSP was the highest. The peak viscosity of the doughs with BSP (200~545 BU) measured by the Amylograph were lower than that of the control (1077 BU). Color L^(*) value of the bread crust and crumb with BSP decreased, and color a^(*) values of the bread crumb with BSP increased, but a^(*) and b^(*) values of the crust with BSP decreased. The hardness, cohesiveness, springiness, and gumminess increased as the concentration of BSP increased. Degree of retrogradations(2.60~4.07) of the bread with BSP was lower than that(6.00) of the control after 48 hrs. From the result of the sensory evaluation, the overall quality score of the bread with 5%-BSP, 4.37, was the highest among samples compared with.

Culdocentesis is a procedure that checks for abnormal Quid in the space just behind the vagina (cul-de-sac). First, a pelvic examination is done. Then, after exposing the postehor vaginal fonix with a bivalve vaginal speculum the posterior lip of the cervix is grasped with a tenaculum. The cul-de-sac is then entered through the postehor vaginal wall with an 18-20 gauge needle with a syringe inserted. As the cul-de-sac is entered, suction is applied, and the intraperitoneal contents are aspirated. In the recent past, culdocentesis was commonly used in the evaluation of a vahety of common intraperitoneal conditions, principally, the hemorrhage associated with ectopic gestations and ruptured ovarian cysts the presence and/or drainage of purulent associated with pelvic inGammatory disease, and as a screening procedure to facilitate early diagnosis of ovarian neoplasms. Usually 16-18 gauge needle with a syhnge attached was used for culdocentesis. But we have experienced a case of therapeutic culdocentesis with 16 gauge angioneedle in patient of hemoperitoneum. So, report it with a bhef review of literature.

Cement mortar and efficient disconnection of aggregate are indispensable for recycling of waste concrete, and the problem is with quality in the existing physical disconnection way, and the problem has been by application of a concrete recycling construction materials. Specially, in case of recycled aggregate, the quality is lowered because of the fine aggregate powder which has a bad influence on flowability, a compression strength by adhesion of mortar on the aggregate face, and the case of recycled cement was added to during recycle cement. Therefore, a mortar and interfacial separation of aggregate are large in proper quality for concrete recycling is expected that affect. This study based on the recycled cement manufacturing way which used an aggregate interfacial separation of waste mortar in this study so that the coefficient of thermal expansion of hardend cement paste and an the coefficient of thermal expansion of a fine aggregate are different in a recycled cement manufacturing way, but leaves a purpose.
