목적 : 관상동맥의 경련에 의한 이형성 협심증환자에 있어서 운동부하 심전도 검사의 결과는 매우 다양하다. 이에 저자들은 충남대학교병원 순환기내과에서 관상동맥조영술상 이형성 협심증으로 확진된 환자를 대상으로 운동부하 심전도 검사를 시행하여 이에 대한 결과를 연구하였다. 방법 : 1995년 1월부터 2002년 3월까지 흉통을 주소로 충남대학교병원 순환기 내과에 입원하여 관상동맥조영술을 시행하여 관상동맥의 내경이 50% 미만의 협착이 있고, 에르고노빈(ergonovine) 유발검사도 이형성 협심증으로 진단을 받은 233명중 운동부하 심전도 검사를 시행 받은 183명의 환자를 연구 대상으로 하였다. 운동부하 심전도 검사 결과의 판독시 발생할 수 있는 오류를 줄이기 위해서 운동부하 심전도 검사를 시행하기전 심전도상 ST분절의 상승(5예)이나 하강(8예)이 있는 경우 EH한 T파의 역위(19예)가 있는 32명의 환자를 제외한 총 151명의 환자를 대상으로 하였다. 운동부하는 Marquette사의 case 15 답차를 이용하였고, Bruce protocol에 따라 증상이 나타날 때까지 최대로 실시하였으며 각 stage 및 운동후의 혈압을 측정하고 12 유도 심전도를 기록하였다. 결과 : 1) 임상적 특성 - 내원시 임상 상은 안정형 협심증이 39예(25.8%), 불안정형 협심증이 103예(68.2%), 심근경색증이 9예(6.0%)이었다. 운동부하 심전도 검사 결과 양성 군과 음성군간에 있어서 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연 여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도, 연축의 수 등을 조사하였는 바 어떠한 인자들도 유의한 차이를 발견할 수 없었다. 2) 운동부하 심전도 검사 - 운동부하 심전도 검사를 시행 받은 151명의 환자중 음성인 경우는 134예(88.8%)이었고, 양성인 경우는 17예(11.2%)이었다. 양성 소견을 보인 환자들중 ST 분절의 상승이 4예(2.6%), ST 분절의 하강이 13예(8.6%)이었다. 3) 관상동맥조영술 - 관상동맥조영술상에서 혈관 경력 위치는 우관상동맥이 70예(46.1%), 좌전하동맥이 44예(28.9%), 좌회선동맥이 17예(11.2%)의 순으로 나타났다. 운동부하 심전도 검사상 ST 분절의 상승이 있었던 예중 Ⅱ, Ⅲ, aVF에서 ST 분절의 상승이 있었던 1예는 관상 동맥조영술상 우관상동맥에서 경련이 발생하였고, V2-V4에서 ST 분절의 상승이 있었던 2예중 관상동맥조영술상에도 좌전하행동맥에서 경련이 나타난 예는 1예이었으며 다른 1예는 좌회선동맥에서 경련이 나타났고, V5-V6에서 ST 분절의 상승이 있었던 1예는 관상동맥조영술상에도 좌회선동맥에서 경련이 나타났다. 운동부하 심전도 검사상 V5 또는 V6에서 ST 분절의 하강이 있엇던 13예중 6예(46.1%)는 관상동맥조영술상 우관상동맥에서 경련이 발생하였고, 3예(23.1%)는 좌전하행동맥에서, 1예(7.7%)는 좌회선동맥에서, 나머지 3예(23.1%)는 2개의 혈관이나 기타 분지에서 경련이 발생하였다. 결론 : 1) 이형성 협심증 환자는 운동부하 심전도 검사에서 11.2%의 양성소견을 보였다. 이중 ST 분절의 상승은 2.6%이었고, ST 분절의 하강은 8.6%이었다. 2) 이형성 환자중 운동부하 심전도 검사를 실시하여 음성을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 3) 이형성 협심증 환자중 운동부하 심전도 검사를 실시하여 ST 분절의 상승을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 4) 운동부하 심전도 검사 결과에 대한 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도 등 어떠한 인자들도 3그룹(ST 분절의 상승, ST 분절의 하강, 음성)간에 유의한 차이를 발견할 수 없었다. 5) ST 분절의 상승 부위와 관상동맥조영술상 관상동맥의 연축이 일어나는 혈관과의 상관관계는 매우 높았다. No reports in the literature describe the results of exercise testings in a large number of patients with pure variant angina(coronary stenosis <50%) in Korea. In this report, We present the results of treadmil exercise testing in 151 patients with variant angina. 151 patients with angiographically proven coronary artery spasm underwent a treadmil exercise test. The clinical characteristics of variant angina patients classified according to ST-segment response to exercise were analyzed. Of 151 patients underwent a treadmil exercise test, negative result was seen in 134 patients(88.8%) and positive result was in 17 patients(11.2%). Of 17 patients saw positive result, exercise-induced ST segment elevation was present in 4 patients(2.6%) and ST segment depression was seen in 13 patients(8.6%). There was not a significant relationship between the ST segment response to exercise and the clinical variables(diabetes, hypertension, obesity, total cholesterol, current smoking, effort angina, clinical diagnosis, and degree of stenosis) assessed. Of 4 patients with ST segment elevation in treadmil exercise test, 1 patient with ST segment elevation in Ⅰ,Ⅲ,aVF had spasm in right coronary artery(100%) on coronary angiography, of 2 patients in V2-V4 had spasm in left anterior descending coronary artery in 1 patient(50%) and 1 patient in V5-V6 had spasm in left circumflex artery(100%). Positive treadmil exercise test was present in 11.2% of variant angina patient. If we have negative treadmil exercise result in patients with clinical manifestation of unstable angina at admission, we may have a suspicion of variant angina rather than multi-vessel disease. If we have exercise-induced ST segment elevation in patients with clinical manifestation of unstable angina at admission, we have a suspicion of variant angina rather than multi-vessel disease. Our result suggests that the correlation between the site of the ST segment elevation and the artery involved is quite good.

The purpose of this study is to discover the architectural type of 「Il-joo-moon」 It deals with 「Il-joo-moon」 that has been built before 1910 in Gyoung-sang province. This study analyzes type of member, jointing method, frame structure method by dividing 「Il-joo-moon」 into four parts such as roof, bracket system, frame structure, podium. The results of this analysis are as follows 1) Roof: The 「Pal-ssac」 style of roof and the 「Matt-bae」 style of roof are dominant and double caves mainly appears. 2) Bracket system: The arrangement of bracket system can be divided into one-line-arrangement and two-line-arrangement. As far as 「Chul-mock-soo」 concerned, 3 or 4 「Chul-mock-soo」 is predominent. 「Tong-jae-gong」 has been used to connect front and back bracket system for some 「Il joo-moon」. When it comes 「jae-gong」, 「Sue-soe」 style, 「Yon-bong」 style and 「Yon-hwa」 style are mainly seen. 3) Frame structure: There are 5 forms in classifying frame structure depending on the jointing method of main-column, diagonal member, sub-column etc. and weight transmission method. 4) Podim: Natural foundation stone is majority. It is judged that 「Il-joo-moon」 has no podium or natural ones, however, it has recently been converted into artificially processed podium in many cases.

Formaldehyde irritiates mucous membranes in the eyes, nose, and upper respiratory tract, and it is a potential carcinogen. The purpose of this study was to assess the time-weighted average (TWA) and short-term exposure limit (STEL) concentration to formaldehyde exposure and to suggest proper improvement strategy to minimize exposure. This study was conducted at 3 histopathology laboratories in the hospitals located in Busan from January 20 to March 10, 2002. Formaldehyde and organic solvents (ethanol and xylene) were sampled by personal air sampler and analyzed by gas chromatography. The obtained results were as follows. 1. TWA concentrations of formaldehyde ranged from 0.28 to 10.64 ppm and those of two laboratories out of 3 were exceeded the threshold limit value (TLV). 2. In one laboratory, STEL concentrations was exceeded threshold limit value (TLV), as 2.39 ppm. 3. TWA concentrations of ethanol and xylene were under the TLVs. It is necessary to improve the local ventilation systems and other facilities to prevent the personnels in the laboratories from the diseases due to formaldehyde exposure.

Background: To access the related factors of depression and to provide the basic data for psychologic problems in patients with peritoneal dialysis. Method: We conducted questionnaire survey using Hamilton depression scale from July to August, 2008. Data were collected from 67 peritoneal dialysis patients who diagnosed end-stage renal disease. Depression was defined over 17 points by Hamilton depression scale. Data analysis were performed with t-test, ANOVA and multiple regression analysis using SAS (ver 9.1). Result: Hamilton depression scale score of patients with peritoneal dialysis was 10.4 ± 5.95 and the prevalence of depression was 28.3%(19/67). The related factors of depression scale in patients with peritoneal dialysis were level of education and health status after peritoneal dialysis. Conclusion: More than quadrant of patients with peritoneal dialysis were suspected depression. In order to prevent depression in patients with peritoneal dialysis, education programs considering their intellectual status and health promotion programs of peritoneal dialysis patients are needed.
