This study investigated the effect of dietary taurine supplementation on the plasma and liver lipid concentrations in lats fed a cholesterol free diet Twenty male-Sprague-Dawley rats(body weight $200{\pm}10g$) were divided into two groups, the control and taurine group(2% taurine supplemented in their diet). All the rats were fed on the experimental diet and deionized water for 6 weeks libitum. There were no significant differences body weight gain, food intake and the food efficiency ratio between the control and experimental groups. The rats fed the taurine diet had a significantly lower triglyceride and AI(athrogenic index) than those fed the control diet The liver total cholesterol (p<0.05) and triglyceride levels(p<0.01) were significantly lower in the rats fed the taurine diet than in those fed the control diet. These results suggest a possible role of taurine as a hypolipidemic agent in male rats fed a cholesterol free diet.
As stomach cancer is very prevalent in Koreans, various factors, especially dietary factors, related to stomach cancer incidence were examined in a case-control study. The study population consisted of 105 individual s diagnosed for stomach cancer in two general hospitals and 124 control subjects, matched for age and sex, in Seoul. Data for general characteristics, family history, smoking and alcohol consumption, personality , dietary habits and food preference were obtained by self-administered questionnaire and personal interview. Heredity was found to be one of the most important factors causing stomach cancer. In addition, genetic inheritance tended to differ between the sexes. The male patients showed significantly higher incidence of their father's relatives than mother's relatives but the female patients showed higher incidence of their mother's relatives that father's relatives. Smoking was significantly related to stomach cancer. It was also found that the cases drank alcohol more frequently and in much greater quantity than the controls. Personality was related to the incidence of stomach cancer. The cases tended to be more sensitive , impatient, and anxious to do things quickly. With regards to dietary habits, the male cases had meals significantly more irregularly than the male controls. The relative risk of preferencefor salty food and ramen showed to be significantly very high. The male cases consumed carbonated beverages and instant foods, low intake of green yellow vegetables, smoking of cigarettes and drinking of alcohol may contribute to the risk of stomach cancer.

Seed, stem and sprout of F. tataricum were separately milled using the ultra fine mill under the same condition to investigate the effect of roasting or extruding on the particle size, microstructure and water solubility of dietary fiber. The mean particle size of MR (roasting) is increased in stem and sprout, and that of ME (extruding) is increased in seed, compared to that of control. The microscopic views of seed show that control has the spherical shape but ME the larger and irregular shape, and those of stem and sprout show that control has the needle like shape but ME more rounded shape. Water solubility index of ME is much higher than that of control or MR in seed, stem and sprout. It shows that seed, stem and sprout are damaged more in extruding than in roasting, and the starch and cell wall structure must be destroyed to change the water insoluble dietary fiber into the water soluble dietary fiber.

Objective: This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. Methods: Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each treatment has five replications with 20 birds each. Four dietary treatments were designated according to the OE supplementation levels (0 as control, 5, 7.5, and 10 g of OE per kg of basal diet respectively). On d 28, a total of 20 birds from each treatment were subjected for ATTR, serum biochemical assay, carcass characteristic and organ weight measurement. Results: Overall weight gain of OE 7.5 g/kg group was higher (p = 0.04) than control group. The ATTRs of dietary energy (p<0.01) and ether extract (p = 0.04) linearly increased with increasing levels of dietary OE. However, no difference in ATTR of dry matter and crude protein was evident. Furthermore, serum IgG concentration increased linearly (p<0.01) and quadratically (p = 0.03) with increasing OE supplementation. No differences in carcass dressing weight and amount of abdominal fat by treatments were observed. Also, the weight of organ including immune organ was not different among the treatments. The TBARS values of 10 d stored breast meat decreased linearly (p<0.01) and quadratically (p<0.01) with increasing dietary OE levels. The meat color was also affected, with lower (p<0.01) redness score in meats from OE supplemented groups. This study showed that dietary OE improved broiler weight gain presumably by increasing feed intake and ATTR of both energy and ether extract. The dietary OE increased serum IgG level and meat anti-oxidation capacity. Conclusion: This study implies that the recommended level of dietary OE supplementation could be beneficial for improving broiler performance and meat quality.
The present study was designed to evaluate the protective effects of dietary vitamin A or E. and of combination of vitamins A and E on peroxidative deterioration of heart in adriamycin-treated rats. Male Sprague-Dawley rats were assigned to 5 groups according to the dietary supplementation of vitamin A or E Except control rats a dose of 2mg ADR/kg of B. W was injected to these animals intraperitoneally on the same day every week. Adriamycin treatment significantly decreased the weight gain of experimental rats compared with that of control rats, But this decrement was not modified by dietary supplementation of vitamin A or E. Lipid peroxide values of plasma were elevated by ADR treatment. The combined use of ADR and dietary vitamin A or E significantly reduced these values, The interaction between vitamins A and E seemed to be present in the lipid peroxide value of plasma. Catalase and superoxide dismutase(SOD) activities in rat heart were decrased by ADR treatment but glutathione peroxidase(GSH-Px) activity was elevated. Dietary supplmen-tation of vitamin A or E enhanced the heart catalase and SOD activities. except only vitamin A-supplemented group. GSH-Px activity of rat heart tended to be decreased by dietary supple-mentation of vitamin A or E. With ADR treatment polyunsaturated fatty acids such as archido-nic acid(20:4) and docosahexaenoic acid(22:6) were decreased in rat heart. However dietary supplementation of vitamins A and E reduced this decrease. The retinol and tocopherol contents of rat plasma were decreased by ADR treatment. Dietary vitamin A or E influence vitamin A or E content of plasma. The interaction between dietary vitamins A and E was observed in vitamin A or E level of rat plasma.
This study assessed the beauty care behavior and the dietary attitudes, eating behaviors, and dietary quality related to beauty care in accordance with the level of interest in beauty care by examining 558 female high school subjects in the Incheon area. The study aimed to identify the interest in beauty care on the part of adolescent girls that impacts their dietary life and provide basic data for nutrition education forming desirable dietary habits. The interest in beauty care on the part of female high school students is relevant to dietary life and dietary attitude, with the high-level interest group attempting to use diet foods more frequently and attempting weight control because of their low satisfaction with their body type. On the other hand, a high level of interest in appearance failed to lead to the practice of a varied and balanced dietary life. Therefore, nutritional education is necessary to avoid a high level of interest in beauty care, leading to an incorrect perception of body shape and excessive weight control. Furthermore, nutrition education is necessary to link interest in appearance to the beauty of a healthy body based on nutritional balance by connecting the interest in appearance to a varied and balanced dietary life that goes beyond the category of practice.
This study was performed to investigate lead(Pb) detoxification with different dietary protein levels and detoxifying periods in Pb poisoned rats. Forty nine male rats of Sprague-Dawley strain weighing 114$\pm$4g were used and they were fed 1% Pb-15% casein diet ad libitum for 2 weeks. After sacrifying 7 animals as control group, remaining forty two rats were blocked into 6 groups according to body weight. Three groups were fed each detoxifying diet(5%, 15% or 40% casein diet without Pb) for 1 week and the other 3 groups were fed same diets for 3 weeks. The results obtained were summerized as follows ; 1) Liver and kidney weight, bone weight, and bone length were increased with increasing dietary protein level and detoxifying period. 2) Hematocrit values were recovered to normal level during detoxifiying periods but hemoglobin contents in detoxifying diet groups showed no significant difference from those in control group. 3)Pb contents in blood were decreased with increasing dietary protein level, and Pb contents in liver were significantly decreased in high protein diet groups. Pb contents in kidney were significantly decreased during detoxifying period compared to control group, but no significant difference was shown within the detoxifying diet groups. Pb contents in femur were significantly decreased after 3 weeks of detoxifying period but no difference was shown with different dietary protein level. 4) Urinary Pb excretions were significantly increased with increasing dietary protein level. Fecal Pb excretions were remarkably decreased after 3 weeks of detoxifying period, but no difference was showen in fecal Pb excretions with different dietary protein level. Above results suggest that high protein diet improves Pb detoxification by increasing urinary Pb excretion.
Our previous study demonstrated that dietary taurine or glycine supplementation significantly lowered plasma and hepatic cholesterol and triglyceride concentrations in rats fed a cholesterol-free diet. In the present study, the effect of long term dietary taurine or glycine supplementation, for the purpose of preventing and/or treating of hyperlipidemia and other known biological functions, on plasma and hepatic free amino acid concentrations and profiles were evaluated in rats. Three groups of male rats(110-130g) were fed a control diet(CD), taurine-supplemented diets(TSD ; CD+ 1.5% taurine) or glycine-supplemented diet(GSD ; CD+1.5% glycine) for 5 weeks. Plasma and hepatic free amino acid concentrations were determined by an automated amino acid analyzer based on ion-exchange chormatography. The feeding of TSD for 5 weeks yielded a 444% higher plasma taurine concentration , and the feeding GSD for the same period resulted in a 143% higher plasma glycine level in rats compared to those fed DB. Hepatic taurine concentration was significantly higher in rats fed TSD(145% increase) compared to the control rats. However, hepatic glycine concentration was not influenced by dietary glycine supplementation , which implies that the massive dose of glycine entering the body was more rapidly metabolized or excreted than taurein. Dietary taurine or glycine supplementation resulted in similar changes in plasma free amino acid concentrations, except in levels of taurine and glycine. Plasma levels of histidine, lysine, phenylalanine , alanine, proline, hydroxypoline, $\alpha$-aminogutyric acid, cystathionine and ethanolamine were significantly higher in rats fed TSD or GSD than those fed GD. Glycine supplementation did not change hepatic free amino acid concentrations as compared to CD. Concentrations of most hepatic free amino acids were not influenced by dietary taurine supplementation with the exception of significantly higher levels of asparate and tyrosine(56-63% increase) and lower levels of histidine and glutamate(33-34% decrease) compared to the control rats. These results suggest long-term dietary taurine or glycine supplementation resulted in increases in most plasma free amino acid levels, but did not cause a characteristic change in plasma aminogram pattern compared to rats fed CD.
The purpose of study was to test the hypothesis that three are differences in body size dietary behavior and nutrient intakes of adolescent girls with weight control experience. Cross-sectional survey was carried out with a questionnaire and anthropometric measurements . Subjects were 724 healthy adolescent girls from middle and high schools of urban and rural areas in Inchon and divided into two subgroups with weight control experience. Subjects trying to lose weigh were 25.1% in middle school girls and 47.1% in high school girls. There were significant differences in weight and BMI between weight control experience and non- experienced groups in middle school students. There were significant differences in skipping meals and reason of skipping meals between weigh control experience and non-experience groups which might show that skipping meal was used as a weight loss method among female school students. There was no significant difference in nutrient intakes between weight control experienced and non-experienced groups in middle and high school subjects. these results suggest that nutrition education is necessary for adolescent girls to practice appropriate weigh control strategies including desirable eating habits and adequate intake of nutrients such as energy vitamin A vitamin B$_2$calcium and iron.
This study was carried out to see dietary intakes of patients with coronary heart disease since we don't understand their dietary patterns even though the mortality and prevalence rate of coronary hear disease are increasing in this country. We studied 75 coronary heart disease patients and 150 randomly selected controls, matched for age, sex, height and weight, in a population based study. All subjects completed a questionnaire that included disease history, diagnosis time, current treatment, etc., a 24 hour dietary recall, and measurement of height and weight. Compared to controls, patients had less likely to drink alcohol and smoke cigarette (p<0.05). The energy intake of patients was significantly lower than that of controls, but the intakes of fiber, $\beta$-carotene, sodium, folate, vitamin C, potassium in male patients and those of vitamin C and sodium in female patients were significantly higher than those of controls (p<0.05). Mean adequacy ratio and dietary variety score of patients were also higher than those of controls (p<0.05). Patient group's consumed less cereals than controls, but more vegetables, milk products, and nuts in male patients and fruits, beans and seasonings in female patients compared to controls'. There were not significant differences of lipid compositions between two groups, except linolenic acid. These data suggest that patients with coronary heart disease in Korea had better dietary nutrient intakes compared to healthy controls, which might be helpful to prevent recurrence of coronary heart disease.
