장임원,정규철,Chang, Im-Won,Chung, Kyou-Chull 대한예방의학회 1977 Journal of Preventive Medicine and Public Health Vol.10 No.1

In order to find out health problems among inhabitants in slum areas in Kwanak-Ku, Seoul, a series of health survey was conducted upon 510 households by interview from March to December, 1976. The results obtained were as follows: 1. Employments of householders were unstable; Out of 508 householders, 164(32.3%) were unemployed and 184 (36.2%) were daily or temporary employees. 2. Average number of households per house was 2.0 and average area of residential room per person was $4.0m^2$. 3. 476(93.3%) out of 510 households were supplied with tap water and rest of them made use of ground water as a source of drinking water. 4. Only 279(18.3%) out of 1527 live births were delivered at medical facilities, 496(32.7%) were at home attended by doctors or midwives and 358(25.1%) took prenatal care. The above findings were worse in urban slum area than in other urban area of relatively high economic level, but were better than in rural area of less medical facilities. 5. Initiation of treatment were delayed until their illnesses were advanced in most of the households, 472(92.5%) out 510. In the early stage of the illness, 131(25.6%) of the house-holds sought physicians in their clinics or general hospitals and 250 (40.9%) visited chemists, to toy drugs at first hand. Frequency of visits to physician increased to 52.8% as the disease aggravated in later stages. 6. Cost of medical expenditure per household amounted to 815 won, and was paid to, in the order of chemists, physicians, chinese herb stores, chinese herb doctors. 7. Concerning the health knowledge of the inhabitants, 273(53.9%) out of 506 respondents were aware of the infectivity of pulmonary tuberculosis, and 68(13.4%) of them checked regularly their chest findings by X-ray at least once every two years. 8. As for the family planning, although 448(87.3%) out of 510 respondents were in favor of it, 215 (41.8%) of them were actually practicing contraception. 9. About 40.6% (125 respondents) of them obtained information and knowledge concerning contraception through personal contact with family planning workers. 10. Nutritional status of housewives was generally poor: 49(38.3%) out of 128 housewives were found to be anemic and average serum protein level was $7.5{\pm}0.82g/dl$.

장임원,Chang, Im-Won 대한예방의학회 1979 예방의학회지 Vol.12 No.1

By evaluating the health status of 152 male workers engaged in a metal-product factory by Cornell Medical Index in conjunction with their experience of industrial accident, I attempted to find out whether any health condition may effect on the occurence of industrial accident. Differences in frequency of complaints in each section of CMI between control workers and accident workers were statistically tested by T-test. On the other hand, influence of neuropsychiatric factors (section M-R) on the occurence of accidents was analyzed by $X^2-test$ with Fukamachi's classification. The followings were the results obtained in this study. 1. The average number (26.42) of physical complaints in accident group is significantly more than in control group (18.70). 2. The average number (17.70) of mental complaints in accident group is very significantly more than in control group (11.70). 3. Differences in frequencies of complaints by sections between accident group and control group was all significant except C (cardiovascular system), H (genitourinary system), I (fatigue) & J (frequency of disease). 4. frequency rate of neurotic workers who were identified by Fukamachi's classification was significantly higher in accident group (72%) than in control group (51%).

An attemption was made to estimate the effect of menopause on the mental health of climacteric women. The Minnesota Multiphasic Personality Inventory (MMPI) were questioned to 278 premenopausal women and 302 postmenopausal women. Data were analyzed by one-way analysis of variance in each variable of menopause, age, educational level, religion and partnership of husband, and two-way analysis of variance in two variables of menopause and one of other variables. The results were summarized as follows. 1. Menopause increased the scores of validity, psychopathic deviate, hypomania and paranoia scale, but conversely decreased the score of masculinity-femininity scale. 2. The older the climacteric women were, the lower scores of masculinity-femininity scale were observed. 3. The older the premenopausal women were, the higher scores of depression, hysteria, psychopathic deviate, psychasthenia and schizophrenia scale were observed, on the contrary, all scores of the postmenopausal women were decreased by the increment of their ages. 4. The higher the educational level of climacteric women were, the higher scores of correction and masculinity-femininity scale were observed, but the scores of hypochondriasis, hysteria, schizophrenia and social introversion scale were decreased by the increment of their educational level. 5. The scores of hypomania scale were higher in women of Buddhism than other religions. 6. The scores of validity, paranoia, psychasthenia, schizophrenia and social introversion scale were higher in widows than women with husband.

To investigate the change of nitric oxide(NO), copper, and zinc in serum on smoking and alcohol ingestion in young adults, this study was performed in a cross-sectional study in 127 healthy men in Korea who had HBsAg(-), HCVAb(-), and no symptomatic liver, heart, gastrointestinal, chronic diseases, and inflammatory sign(lower than 10,000 white blood cell count in CBC). At the men's entry into the study, blood samples were drawn from each subject and immediately centrifuged for analysis of NO, copper, and zinc. Each man completed a questionnaire that provided information on smoking, alcohol intake and present and past medical history NO was analyzed by HPLC(Green et al., 1982), copper and zinc by atomic absorption spectrophotometer with air-acetylene flame and total cholesterol(TC) by Spectrum EPX. Smoking(number of cigarettes per day and pack-year) and alcohol intake was grouped fertile. Copper was adjusted for age and zinc and for age and TC. NO, copper, and zinc on smoking and alcohol ingestion were analyzed in general linear models, respectively. NO, copper and zinc in serum did not show statistical differences between non-smoking and high-smoking group and no-alcohol intake and high-alcohol intake group. This study suggested that copper, zinc, and NO was not. good biological marker for early effect by smoking and alcohol intake in young adults. However, selection bias should be considered in evaluation of this result. A large prospective study will be needed in advance on usefulness of copper, zinc, and NO as a marker for risk factors and early change of atherosclerosis.

흰쥐와 마우스에서 Ethanol이 요중 트리클로로에틸렌 대사산물 배설량에 미치는 영향

강은용,박정덕,홍연표,장임원,Kang, Eun-Yong,Park, Jung-Duck,Hong, Yeon-Pyo,Chang, Im-Won 대한예방의학회 1998 예방의학회지 Vol.31 No.4

본 연구는 흰쥐와 마우스에서 TCE 경구투여 후 주대사산물인 TCE-OH와 TCA의 요중 배설량과 시간에 따른 배설량의 변화와 이에 대한 ethanol의 영향 및 종간의 차이를 조사하여 다음과 같은 결과를 얻었다. 1. TCE 경구 투여 후 요중 TTC 배설양상은 실험동물의 종간에 현저한 차이가 있었으며, 흰쥐에서는 TTC 배설량이 투여량에 따라 증가하다가 체중 kg당 1,000 mg 용량 이상에서 포화되는 양상을 나타내었으나, 마우스에서는 2,000 mg까지 거의 선형적으로 증가하였다. 투여용량에 따른 TTC 배설 량은 흰쥐보다 마우스에서 유의하게 높았다(p<0.01). 2. TCE 투여 후 경과시간에 따른 대사산물 배설양상은 종이나 투여용량에 관계없이 비슷한 양상을 나타내었다. TCE-OH는 12시간에서 거의 대부분$(82.8\sim87.6%)$이 배설되었으며, TCA는 12 시간 $(39.2\sim41.6%)$과 24시간$(33.4\sim36.6%)$에 최고치를 보였고 그 후 서서히 배설되었다. 3. Ethanol 전처치시 횐쥐에서는 TTC와 TCE-OH 배설량이 유의하게 증가하였으나(p<0.01), TCA 배설량은 증가하지 않았다. 마우스에서는 TTC, TCE-OH 및 TCA 배설량 모두 ethanol 군과 대조군 사이에 유의한 차이가 없었다. This study was conducted to examine the species differences in the urinary excretion of trichloroethanol(TCE-OH) and trichloroacetic acid(TCA) of trichloroethylene (TCE) metabolites and the effect of ethanol on these metabolites in mice and rats. TCE administered to Male Sprague Dawley rats and ICR mice as a single oral dose(100, 200, 500, 1,000 or 2,000 mg/kg body weight) and ethanol(3.0 g/kg body weight) was taken orally 12 hours before TCE administration. The metabolites in urine were measured 0, 12, 24, 36 and 48 hours after TCE administration. The results of metabolite excretion were as follows; Total trichlorocompounds(TTC) in urine increased with TCE dose in mice while increased only below dose of 1,000 mg/kg TCE in rats. The net excretion of TCE metabolites was significantly greater in mice than rats, although the proportion of TCE-OH to TCA was not different between mice and rats. These findings indicate that mice were internally exposed to significantly higher concentration of TCE metabolites than rats and this trend appeared to be more prominent with the increase of TCE dose. Ethanol increased significantly TCE-OH in urine of rats while the increase of TCE-OH induced by ethanol was not significant in mice, and didn't increase TCA of urine in both of rats and mice. This result suggests that the effect of ethanol on TCE metabolism may be due to the increase of TCE-OH.

Pulmonary function tests were conducted on 815 healthy primary school children (390 males and 425 female) in rural area using Collins Survey Spirometer (Warren E. Collins, Inc., U.S.A.) with X-Y Recorder. Respiratory symptoms(cough, sputum, sore throat, chest pain, chest tightness, dyspnea, coryza) were surveyed by the interviews. Multiple regression analysis and regression diagnostics were done for prediction equations of FVC, $FEV_1,\;PEFR\;and\;FEF_{25-75%}$. FVC, $FEV_1,\;PEFR\;and\;FEF_{25-75%}$ values in 3 groups of children classified by the number of symptom were compared each other through standard variable value. FVC, $FEV_1,\;PEFR\;and\;FEF_{25-75%}$ showed highly significant correlation with age, height and weight. Prediction equations for FVC, $FEV_1,\;PEER,\;FEF_{25-75%}$ are functions of height only in both male and female children aged between 6 and 12 years old. PEFR showed a significant difference related with the number of symptom in female. These results suggest that the PEFR is sensitive PFT parameter in this study.

민경준,박정덕,홍연표,장임원,Min, Kyung-Joon,Park, Jung-Duck,Hong, Yeon-Pyo,Chang, Im-Won 대한예방의학회 1993 Journal of Preventive Medicine and Public Health Vol.26 No.2

Thirty five male Sprague-Dawley rats were treated with cadmium chloride solution ranging from 0.2 to 3.2mg $CdCl_2/kg$ by intravenous single injection. At 48 hours after administration of cadmium, total cadmium, MT bound cadmium and histopathologic finding in liver, kidney, lung, heart, testis, metallothionein in liver, kidney and total cadmium in bleed were examined. Tissue cadmium concentration was highest in liver, followed by in kidney, heart, lung and testis. Cadmium bound to rnetallothionein (MT-Cd) and ratio of MT-Cd to total cadmium were increased in liver and kidney dependently of cadmium exposure dose, but not significantly changed in other organs. On histopathologic finding, the most susceptible organ was heart in considering cadmium exposed dose, but testis in considering cadmium concentration. Blood cadmium concentration was increased with dose-dependent pattern, and significantly correlated with tissue cadmium concentration, so that we may estimate tissue cadmium concentration by measurement of blood cadmium concentration. Metallothionein in liver and kidney was increased with dose-dependent pattern, higher in liver than in kidney, and was significantly correlated with tissue cadmium concentration. However, metallothionein induction efficiency of tissue cadmium(${\mu}g\;MT/{\mu}g\;Cd$) was eater in liver than in kidney, and reverse to tissue concentration or exposed dose of cadmium.
