김현덕 기전여자대학 1995 論文集 Vol.15 No.-

The purpose of this study is to determine the effects of different dietary proteins on the hepatic histological changes in the chemically induced hepatocellular carcinogenesis. Weanling Sprague Dawley rats fed the diets containing casein(source of animal protein) and soy protein(source of plant protein) at the level of 20%(W/W) were treated with DEN as control group and treated with DEN followed by AAF and PB as treatment group, and then sacrificed at 6th and 10th wk after feeding diet. Diet intake, body weight, relativ liver weight, and hepatic histological changes were determined. Diet intake and body weight were higher in casein groups. Relative liver weight was increased in treatment group. The degree of hepatic histological changes, esfecailly, fatty changes and hyperplastic nodule formation, was higher in casein groups than in soy protein groups. This results suggest that casin diets are associated with a greater susceptibility of the animals to the acute effects of the carcinogen than soy protein diets.

화학적발암원으로 유도한 간세포 암화과정에서 단백질 수준이 간손상지표들에 미치는 영향

김현덕 기전여자대학 2000 論文集 Vol.20 No.-

Six -week-old Sprague dawley rats were fed a diet of 5, 10, 20% protein diet. Two weeks after diet feeding, hepatocellular chemical carcinogenesis were initiated by diethyl nitrosamine(DEN), and promoted by the diet containing 0.01% 2-acetylaminofluorene (AAF) and two-thirds partial hepatectomy (PH). The animalals were sacrificed 4 days and 8weeks after the DEN injection. The serum glutamic oxaloacetic transaminase(GOT), serum glutamic pyruvic transaminase(GPT) and glucos 6-phosphatase(G6pase) were determined to investigate the anticarcinogenic effect of dietary proteins on rat hepatocellular carcinogenesis. Relative liver weight was significantly increased in the rats fed 5% casein at promotional period. The serum GOT activities were significantly higher in rats fed casein 5% than rats fed 10% or 20%casein at initiation period, however at promotional period, both serum GOT and en activities were significantly higher in rats fed casein 5% than rats fed 10% or 20%casein. Glucos 6-phosphatase whose activity decrease as cancerous cells develops and is used as an indicative measure for the membrane stability, was decreased by the DEN initiation and was the lowest in the rats fed 5% casein. Thease results suggest that the the diet containing lower level protein than 5% may increase the initiation and promotion of chemical hepatocellular carcinogenesis.

2-AAF투여량과 BHT가 다른 식이지방을 먹인 쥐 간의 Cytochrome b5 및 지질 과산화물 함량에 미치는 영향

김현덕 기전여자대학 1992 論文集 Vol.12 No.-

Weanling male Sprague Dawley rats were fed the diet of beef tallow(P/S 0.08) and soybean oil(P/S 4.0) at the level of 15% fat with and without 0.3% BHT. After 8 weeks of feeding, 25mg and 100mg/kg/day of 2-AAF was injected for 3 days and sacrificed the next day. Cytochrome b5 and lipid peroxide values were determined from isolated microsomes. Cytochrome b5 was not infloenced by dietary fats and 2-AAF levels but increased by BHT. Lipid peroxide values were not influenced greatly by dietary fats, 2-AAF levels and BHT. However, AAF 100-BHT groups were higher than anyother group, and soybean oil group was higher than beef tallow group only in AAF 25 group. This results suggest that BHT induced cytochrome b5 to protect the cell from toxic effects of carcicogen.

Hard type ABS 分解菌의 分離 同定 및 生理化學的 硏究

洪淳德,河炫八 慶北大學校 1983 論文集 Vol.35 No.-

A microorganism to enhance the biodegradability of hard type ABS of commercial synthetic detergents was isolated from the sewage sludge of Apt. areas and identified as Klebsiella pneumoniae. In the basic mediums to grade the ABS concentration, growth of the selected strain was inhibited above ABS 2,000ppm and degradability of hard type ABS was higher as the start concentration was lower. When the start concentration of ABS was especially 40ppm, degradable rate leaded to about 70% within 15 hr culture. PH range for the culture of the selected strain was between 5 and 10. Hg^++ ion of 11 metal ions was the most sensitive to the growth of the selected strain in the basic medium with ABS 400ppm; the minimum concentration of Hg^++ at complete growth inhibition was 10^-2mM. Degradability of Na-DBS by the strain in shaking culture was higher than that in static culture until 3 day culture. The degradable rate of Na-DBS by the selected strain was generally higher that of Na-SSE, and after 7 day culture the former was 81%, the latter 69%, respectively. The selected strain cultured in the basic medium with Na-DBS 5,000ppm did not show its nucleus and black spots regarded as condensation of nucleus near the cell wall were formed. And also the forms of cell wall and cell division were not abnormal.

男子大學生의 營養知識과 食習慣에 관한 調査硏究

地宣京,金賢德 기전여자대학 1991 論文集 Vol.11 No.-

The objective of this study is to investigate male college student's nutrition knowledge level and food habits and their correlation. The questionnaires answered by 378 male college students were analyzed for nutrition knowledge, food habits and their correlation. The subjects had a high level of perceived knowledge(85% ), that is the knowledge that each subject believed he had, but the accuracy of that knowledge was 71%. The mean nutrition knowledge score was 12 out of a possible 20 points, and habit score was 4.4 out of 10 points. Therefore most of the subjects had a high level of nutrition knowledge but belonged to the "Fair" food habit group, which is considered to be relatively poor. There was a Positive correlation between nutrition knowledge score and food habit score of the subjects. Furthermore with increasing monthly income and level of education of their parents, the food habit scores also increased. There was a positive correlation between nutrition knowledge score ad their mother's employment status. Meanwhile, the food habits of male college students show that the consumption level of fruits, milk and sea weed is relatively low, but vegetables consumption was normal and they ate breakfast everyday. Meals were never missed for reducing weigth. Seventy-nine percentage of the subjects have not been educated in nutrition. Most of the male students have mainly obtained nutritional information( knowledge) from mass media.

The purpose of the survey was to study of anthropomeric measurements of elderly in Jeon-Ju area. One hundred seventeen (males 36, females 81) subjects aged from 65 years to 74 years. The average height and weight of the subjects were 164.1cm and 61.1kg in males and 151.6cm and 54.1kg in females. Height and weight in males were significantly higher than in females(p<0.001). W/H is also significantly higher in males than that of females(p<0.01). This indicates that fat distribution of males tend to be centralized toward the trunk of the body than females. But, ST, BFW and BF(%) in females were significantly higher than in males. The subjects were classified as 16.2%, 26.5% and 26.5% obesity by BMI, OR and PIBW, respectively. The subjects were classified as 16.2%, 26.5% and 57.3% overweight by BMI, OR and PIBW, respectively. The subjects were classified as 7.7%, 0% and 0% underweight by BMI, OR and PIBW, respectively. In males, obesity index(BMI, OR, PIBW) were strong positively correlated with waist(p<0.001). In female, obesity index(BMI, OR, PIBW) were strong positively correlated with BFW, hip(p<0.001).

Objectives : A study was conducted for investigating the status of simple X-rays on lumbo-sacral regions at pre-employment health examination and analysing the effectiveness of simple X-rays on lumbo-sacral regions. Methods : The study data were pre-employment health examination data in a university hospital from Jan 3, 1993 through October of 1997. And, 97 newly employed workers who claimed no low back pawn at pre-employment health examination of a certain company were follow-up survey about low back pain and related factors in April, 1995 and October of 1997. The data were collected by a self-reported questionnaire and a medical examination with a rehabilitation specialist. Results : 1. Taking the simple X-rays on lumbo-sacral regions was 1,591 workers (10.5%) among 15,166 pre-employment health examination from Jan 3, 1993 through October of 1997. And yearly application rates of these X-ray tests have been significantly statistical increasing (p〈0.01). 2. The abnormal findings of simple X-rays on lumbo-sacral regions at pre-employment health examination were 40 workers. But, there was not significantly statistical difference between normal and abnormal group for the complaint rate of low back pain. 3. The number of case with symptoms of low back pain at the follow-up survey were 46, so The incidence density was 37.1 persons/ 100 person-years. And the incidence density was not significantly statistical difference between normal and abnormal group of simple X-rays on lumbo-sacral regions. 4. Through the multivariate logistic regression, significantly associated factors with low back Pain were found to be tenure(OR=0.36, 95%CI : 0.17-0.79), lifting of heavy materials (OR=5.86, 95%CI : 1.58-21.74) . Conclusion : The simple X-rays on lumbo-sacral regions at pre-employment health examination is required further research for utilizing pre-employment health examination according to above results.
