We have experienced a case of radiation-induced coronary biostial stenosis presented with recurrent syncopal attack, which was confirmed by coronary angiography and pathologic findings. A 60 year-old woman was admitted with the symptoms of recurrent syncopal attack. She had a history of radiation therapy of the chest for lung neoplasm 15 years ago. Initial electrocardiogram showed transient high-degree A-V block followed by third-degree atrioventricular block which was associated with syncope. Echocardiography revealed mild aortic regurgitation without left ventricular dysfunction. The coronary angiogram revealed biostial stenosis of coronary arteries. Initial cardiac symptom subsided after temporary pacemaker implantation. She had a coronary bypass graft surgery on both coronary arteries using saphenous vein. Biopsy findings showed mild fibrosis with intimal thickening of coronary artery.

A microfluidic electrochemical aptasensor for enrichment and detection of bisphenol A.

<P><B>Abstract</B></P> <P>Bisphenol A (BPA) is an organic monomer used to make common consumer goods such as plastic containers, sports equipment, and cosmetics which are heavily produced worldwide. A growing interest has been drawn to general public as BPA is one of the major endocrine disrupting chemicals threating human health. To date, numerous BPA sensors have been attempted to be developed but important challenges still remained such as limited linearity range, easy to use, and long term response time. To address the present issues, a microfluidic channel should be integrated into an electrochemical aptasensor and it is called Geometrically Activated Surface Interaction (GASI) chip. The vigorous generation of the micro-vortex in the GASI fluidic chamber provides the high collision chances between BPA and anti-BPA aptamer (BPAPT) and consequently more BPA molecules can be captured on the aptasensor surface, which finally results in high sensitivity of the aptasensor. To construct the integrated aptasensor, a miniaturized gold electrode is fabricated using shadow mask and e-beam evaporation process. Afterward, BPAPT is immobilized on a nanostructured gold electrode via thiol chemistry, and other terminus of the aptamer is labeled with a ferrocene (Fc) redox probe. Then, the microfluidic channel is mounted over the miniaturized gold electrode to introduce and enrich BPA to the aptasensor. Upon the specific interaction between BPA and its aptamer, configuration of aptamer is changed so that Fc tag approaches to the electrode surface and direct oxidation signal of Fc and BPA are followed as analytical signals. The unique microfluidic integrated electrochemical aptasensor delivers a wide linear dynamic range over 5 × 10<SUP>–12</SUP> to 1 × 10<SUP>−9</SUP> M, with a limit of detection 2 × 10<SUP>–13</SUP> M. This aptasensor provides a precise platform for simple, selective and more importantly rapid detection of BPA. Such kind of sensing platforms can serve as a fertile ground for designing miniaturized portable sensors.</P> <P><B>Highlights</B></P> <P> <UL> <LI> GASI generates micro-vortex resulting in enhanced capture of BPA and subsequently enhanced sensitivity of the aptasensor. </LI> <LI> The aptasensor has low LOD, wide linear dynamic range and good response time compared to conventional aptasensors. </LI> </UL> </P>

Background: Asiatic acid is a putative anticancer agent in several types of cancer cells. Researches of its biological role in negative regulation of cell growth have focused on the extent of induction of apoptosis in a cell-type-specific manner. Objectives: To identify the mechanisms underlying asiatic acid-induced downregulation of BCL2. Methods: MicroRNA microarray analysis was used to investigate the effect of asiatic acid treatment of A549 cells on miRNA expression profiles. We used quantitative RT-PCR to confirm the asiatic acid-induced increase in miR-1290 level with primers specific for the mature miR-1290 sequence. We also assessed the effect of asiatic acid on the levels of BCL2 in A549 cells using western blot analysis. Results: We identified an important regulator of asiatic acid-induced cell death, microRNA (miR)-1290, which sensitizes cells to Asiatic acid-induced cytotoxicity and negatively regulates BCL2 expression. Asiatic acid significantly upregulated miR-1290, and asiatic acid-induced cell death was shown to be dependent on miR-1290 activity. Molecular assays demonstrated that BCL2 mRNA is a direct target of miR-1290-mediated RNA interference. Conclusion: The findings of the present study suggest that miR-1290 suppresses cell viability and cell cycle progression. Our results provide insight into miR-1290-mediated cellular mechanisms in asiatic acid-treated A549 non-small cell lung carcinoma cells.

The present study aims to develop the digital content of a smart-phone app for the measurement and management of depression – a key issue in adolescents’ mental health. This app has been developed by a psychology laboratory and a computer software engineering laboratory for an interdisciplinary convergence study. The target users of the app are adolescents who participate in group counseling for prevention and management for depression. The app is planned to be used as a tool for the group counseling. To develop the app content, we conducted a literature review. We then comparatively analyzed the key aspects of existing domestic and foreign apps designed to help for depression. The results of the analysis suggested the Beck Depression Inventory-II for the assessment method, the cognitive behavioral approach for the psychotherapeutic approach, and the group counseling that allows mutual support. Therefore, in this study, we organized and developed the app content by focusing on the identified aspects and conducted a pilot test with five adolescents to determine if the app met the development objectives. Modifications and improvements will be made based on the suggestions obtained from the pilot test and expert reviews. In conclusion, this app content is expected to enhance the wellness of adolescents effectively by improving proactive emotional management on a daily basis.

오성수,최용휴,김은아,이영목,장재길,유장진,박승현,김태균,정수영,김규상,강성규 大韓産業醫學會 2006 대한직업환경의학회지 Vol.18 No.2

목적: 제약회사에서 직업상 천식의 유병 규모를 파악하고 작업공정에 대한 작업환경 측정을 통해 제약회사의 약제 분말에 대한 노출수준을 평가하고자 하였다. 방법: 제약회사에서 약제 분말에 노출되는 근로자를 대상으로 천식을 선별하기 위하여 설문조사 및 진찰, 혈액검사, 폐기능 검사 그리고 피부단자시험을 실시하였고, 각 부서별 공정에 따라서 총분진과 항생제 또는 효소제 분말에 대한 작업환경 측정을 실시하였다. 직업상 천식이 의심되는 근로자에 대하여 기관지과민성에 대한 검사(메타콜린을 이용한 비특이 기관지유발시험)와 약제 분말 기관지유발시험을 실시하여 확진하였다. 결과: 설문조사 및 진찰에서 작업 관련 천식 증상이 있는 근로자는 11명(34.4%)이었고, 약제 분말을 이용한 피부단자시험에서 1+ 이상 반응을 보인 근로자 10명(31.2%)이었다. 비특이 기관지유발시험 결과 8명(25.0%)이 양성(PC20 ≤16 mg/ml)이었다. 약제 분말 기관지유발시험을 통해 직업상 천식으로 확진된 근로자는 5명(15.6%)이었다. 작업환경 측정에서 원료를 충진하거나 투입하는 작업 그리고 정립작업에서 약제 분말에 대한 노출이 많았다. 결론: 제약회사에서 직업상 천식은 주로 제조공정 중 약제 분말에 노출된 근로자에서 발생하여, 증상 및 직업성 천식의 유병률이 높았다. 따라서 원료를 충진 또는 투입하는 작업과 정립작업 등 제조과적에서 약제 분말 노출을 줄이기 위한 세심한 주의가 필요하여, 약제 분말을 취급하는 근로자에 대해서는 천식 증상 조사뿐 아니라 정기적으로 피부단자시험, 비특이 기관지유발시험 등을 실시하여야 할 것이다. Objectives: After the investigation of one worker with occupational asthma, we surveyed the preva- lence of occupational asthma and the exposure level of pharmaceutical dust of 32 workers in a pharmaceutical company. Methods: Thirty-two of the 90 employees participated in the survey which consisted of questionnaire, blood sampling, spirometry and skin prick tests with 8 common allergens as well as 9 antibiotics and 2 enzymes. Various indices of the working environment were also measured. Subjects who had a symptom suggestive of work-related asthma or positive skin prick test were further investigated by PC20 methacholine. Nine subjects who had a PC20 result of 16 mg/ml or less (n=7) or had work-related symptoms and positive skin prick test (n=2) were referred to undergo a specific bronchial provocation test to phar- maceutical dust in an academic allergic disease center. Results: Eleven of 32 workers (34.4%) had a work-related symptom suggestive of occupational asthma. Ten (31.2%) showed positive skin prick test. 8 (25.0%) had a PC20 result of 16 mg/ml or less (indicative of significant bronchial hyperresponsiveness), and 5 (15.6%) had a positive result on the specific bronchial provocation test. Exposure levels of stuffing, input of raw materials and screening process were relatively high. Conclusions: This survey showed that pharmaceutical workers have an increased risk of occupational asthma. Although pharmaceutical factories maintain a relatively good working environment, careful control of respiratory tract exposures, especially during stuffing, input or raw materials and screening process, is important to prevent occupational asthma. Pharmaceutical workers need to undergo regular skin prick and methacholine bronchial provocation tests, as well as asthmatic symptom survey, to ensure the early detection and prevention of occupational asthma.

요로 감염증 환아에서 배뇨성 요로조영술을 시행하는 적절한 시기에 대한 평가

이정아,최제은,김성미,정진화,Lee Jung A,Choi Jae Eun,Kim Sung Mi,Jung Jin Hwa 대한소아신장학회 2001 Childhood kidney diseases Vol.5 No.2

목 적 : 요의 감염증 환아에서 방광 요관 역류는 흔히 발견되는 이상으로 대부분의 연구에서 요로 감염 3-6주 후 VCUG를 시행하는 것을 권유하고 있다. 하지만 검사를 하기 위해 기다리는 동안 만성 신질환으로 진행할 가능성이 있으며 추적 관찰에 실패하여 검사자체를 하지 못 하는 환아가 발생 할 수 있다. 따라서, 본 연구에서는 요로 감염 후 VCUG를 시행하는 시기가 요관 방광 역류의 빈도와 정도에 영향을 미치는지를 조사하였다. 대상 및 방법 : 1997년 3월부터 2000년 12월까지 요로 감염으로 메리놀병원 소아과에 내원한 환아 213명을 대상으로 후향적으로 조사하였다. 이들 환아를 요로 감염 진단 후 1주일 이내에 VCUG를 시행한 군(A군, 142명)과 1주일 이후에 VCUG를 시행한 군(B군, 71명)으로 나누어 각각을 비교하였다. 결 과 : A군의 $19\%$(27/142명), B군의 $18\%$(6/71명)에서 역류가 발견되었으며 통계학적으로 의미 있는 차이가 없었다(P=0.854). 하지만, 실제로 계획된 VCUG를 받은 환아는 A군 $100\%$, B군 $48\%$로 의미있은 차이가 있었으며(P<0.001), B군 환아에서 감염 후 VCUG를 받은 기간과 역류 정도에는 의미 있는 차이가 없었다(P=0.001). 결 론 : 본 연구의 결과에 따르면 요로 감염후 VCUG를 하는 기간과 역류의 빈도와 정도에는 차이가 없으므로 환아가 입원하고 있는 동안 VCUG를 시행하는 건이 더욱 바람직하며 이에 대한 보다 많은 연구가 필요하다고 생각한다. Purpose : Urinary tract infection is a common problem in children. To evaluate for reflux most authorities recommend a voiding cystourethrogram 3 to 6 weeks after the first urinary tract infection. But during the 3 to 6 weeks interval, patients may fail to show up for the scheduled VCUG and thus risk for loss of follow up. We analyzed patient's records to evaluate whether the timing of VCUG after UTI influenced the prevalence or severity of VUR. Methods : We retrospectively reviewed 213 children diagnosed with UTI from March 1997 to December 2000. These children were divided into 2 groups according to whether they had VCUG scheduled to be performed either within 1 weeks after the diagnosis of UTI (Group A) or later than 1 week after the diagnosis(Group B). We compared tile presence and severity of reflux in the 2 groups. Results : Reflux was present in $19\%$ of the patients studied within 1 week after UTI and in $18\%$ of those studied after 1 week. This difference was not statistically significant. Whereas $100\%$ of the scheduled VCUGs in the Group A were performed, only $48\%$ of those scheduled in the Group B were performed. This difference is statistically significant. Conclusion : Because there was no significant difference between the presence or severity of reflux and timing of VCUG after UTI, we suggest that a hospitalized patient with UTI should have VCUG performed before discharge.

변신연 ( Shin Yun Byun ),배윤진 ( Yun Jin Bae ),유재호 ( Jae Ho Yoo ),정진아 ( Jin A Jung ) 대한소아알레르기호흡기학회(구 대한소아알레르기 및 호흡기학회) 2006 소아알레르기 및 호흡기학회지 Vol.16 No.4

목적: Mycoplasma pneumoniae는 학동기 소아에서 호흡기 감염의 주된 원인균이며, 마이코플라즈마 폐렴의 호흡기 합병증으로는 무기폐, 늑막 삼출, 폐농양, 폐기종, 기관지 확장증 등이 있다. 이번 연구에서는 마이코플라즈마 폐렴에서 늑막 삼출 유무에 따른 임상 양상의 특징을 비교해보고자 하였다. 방법: 2000년 1월부터 2004년 12월까지 동아대학교의료원 소아과에 입원한 마이코플라즈마 폐렴 환자 210명을 대상으로 입원 기록을 후향적으로 비교분석하였다. 마이코플라즈마 폐렴의 진단기준은 항 마이코플라즈마 항체역가가 1:320 이상인 경우로 하였으며 늑막 삼출을 동반한 경우(A군)와 동반하지 않은 경우(B군)로 나누어 성별, 연령, 발생시기, 증상, 이학적 소견, 검사 소견, 흉부 방사선 소견을 비교하였다. 결과: A군과 B군 간의 연령, 성별, 발생시기, 증상 및 청진 소견에서는 유의한 차이는 없었다. 발열기간과 입원기간은 A군이 B군보다 의미있게 길었다.(P<0.001) 적혈구 침강속도는 A군에서 49.6±32.9㎜/hr로, B군의 28.7±20.4㎜/hr보다 의미있게 높았으며(P=0.001), C-반응성 단백은 A군에서 23.0±60.4㎎/dL로, B군의 8.7±30.9㎎/dL보다 의미있게 높았고(P=0.004), SGOT와 SGPT는 A군이 각각 67±74.2 IU/L와 53.6±60.0 IU/L로, B군의 37.4±18.6 IU/L와 26.2±16.9 IU/L보다 의미있게 높았다. (P<0.001) 늑막 삼출 유무와 항 마이코플라즈마 항체역가 사이의 유의성은 없었다. 결론: 늑막 삼출이 동반된 마이코플라즈마 폐렴군에서 발열기간, 입원기간, 적혈구 침강속도, C-반응성 단백, SGOT, SGPT가 늑막 삼출이 동반되지 않은 군에 비해 유의하게 증가되어 있어, 이러한 검사 소견들을 통하여 치료 경과를 예측할 수 있을 것으로 생각한다. Purpose: Mycoplasma pneumoniae (M. pneumoniae) is a major cause of respiratory infections in school-aged children. Complications of M. pneumoniae pneumonia include atelectasis, pleural effusion, empyema, pneumothorax and bronchiectasis. We evaluated the clinical characteristics of M. pneumoniae pneumonia with pleural effusion. Methods: A total of 210 medical records of children who were admitted to the Dong-A University hospital due to M. pneumoniae pneumonia from 2000 to 2004 were retrospectively analyzed. Diagnosis of M. pneumoniae pneumonia was based on the single titer of antimycoplasmal antibody higher than 1:320. Enrolled children were divided into Group A (with pleural effusion) and Group B (without effusion). We analysed the differences between the two groups according to sex, age, onset, symptoms, clinical manifestations, laboratory findings and chest x-rays. Results: There were no significant differences in age, sex and clinical manifestations between the two groups. Group A had longer fever durations (9.3±7.8 days vs 5.0±3.7 days), and a longer duration of hospitalization (10.4±6.3 days vs 6.9±6.3 days) compare to Group B. Also, compared to the Group B, Group A had higher ESR (49.6±32.9㎜/hr vs 28.7±20.4㎜/hr), CRP (23.0±60.4㎎/dL vs 8.7±30.9㎎/dL), SGOT (67±74.2 IU/L vs 53.6±60.0 IU/L), SGPT (37.4±18.6 IU/L vs 26.2±16.9 IU/L). There was no significance between antimycoplasmal antibody titer and pleural effusion. Conclusion: This study shows that M. pneumoniae pneumonia with pleural effusion has a longer duration of fever and hospitalization, higher ESR, CRP, SGOT, SGPT compare to the M. pneumoniae pneumonia without pleural effusion. We conclude that these findings could be used as the prognostic factors in M. pneumoniae pneumonia with pleural effusion. [Pediatr Allergy Respir Dis(Korea) 2006;16:327-334]
