The purpose of this study was to investigate the pattern of individual fatty acid intake and to compare total serum lipid levels and total serum fatty acid composition of elementary school children in Seoul by fish and meat intakes. The subjects were divided into High-Fish / Low-Meat(HFLM, n=49) and Low-Fish/High-Meat(LFHM, n=47) group. The total energy from fat of HFLM and LFHM group was 22.0 and 30.0% respectively. The average intake of cholesterol was 237-287mg in HFLM group and 358-387mg in LFHM group. The average P/M/S ratio for all subjects was 1.1-1.4/1.1 - 1.2/1.0, which was very similar to desired ratio. The $\omega$6/$\omega$3 ratio of dietary fatty acids of HFLM and LFHM group were 8.0-10.9 and 18.9-29.3 respectively, which in case of LFHM group, was fat beyond the suggested range, 4/1 - 10.1. Serum lipid levels of all subjects fell within the normal range and there was no significant difference in serum lipid levels between HFLM and LFHM groups, except for HDL-cholesterol in upper grades(4th-6th grades). In lower grades(1st-3rd grades), serum PUFA composition of HFLM (40.8%) group was significantly higher than that of LFHM (38.3%) group (p<0.05) and SFA composition of HFLM(33.8%) was significantly lower than that of LFHM group, (p<0.001) between them. The $\omega$6/$\omega$3 ratio of serum fatty acid tended to be higher in LFHM than in HFLM group but there was no significant difference between two groups. This study suggests that the dietary fat pattern of growing children could affect the change in total serum fatty acid composition though it did not influence serum lipid levels significantly. Energy and EPA intakes were negatively correlated with HDL-cholesterol levels(p<0.05). Serum fatty acid compositions were more closely correlated with serum triglyceride(TG) levels than serum cholesterol levels. Especially, total SFA (p<0.001) and individual SFA, such as C14:0(p<0.001) and C16:0(p<0.001)compositions were positively correlated with serum TG levels, but stearic acid(p<0.01) was negatively correlated with it.

In order to investigate the effect of smoking on serum lipid pattern and nutrient intake, the subjects, 134 smokers and 113 nonsmokers, were selected from college men student in Kwangju area. We examined the serum lipid pattern of 15 smokers and 18 non-smokers who agreed to venipunture among the subjects and also examined nutrients intake. The results obtained were as follows ; Mean concentrations of 새심 cholesterol, HDL-cholesterol and LDL-cholesterol were 187$\pm$12.1mg/dl, 41.5$\pm$1.7mg/dl, and 87.3$\pm$7.4mg/dl in smokers and 182.6$\pm$8.2mg/dl, 45.5$\pm$1.5mg/dl, and 96.3$\pm$4.3mg/dl in nonsmokers, respectively. The total energy intake was 2264kcal/day and mean constitutional rationof protein, fat and carbohydrate was 12.7 : 24.8 : 62.5 in smokes and 2287kcal/day, 14.1 :25.4 : 60.5 in nonsmokers, respctively. Mena daily intakes of calcium, iron, vitamin C and vitamin A were 612.2mg, 15.7mg, 48.2mg 2029.4 IU in smokers and 629.4mg, 15.3mg, 68.4mg 2339.1 IU in nonsmokers, respectively. Vitamin C intake was significantly different at p<0.05 between the smokers and nonsmokers. Intakes of cholesterol, SFA and MUFA were not significantly different between the two groups. Mean daily PUFA intake of smokers and nonsmokers were 5.5g and 6.9g respectively. PUFA intake was significantly different at p<0.05 between the two groups. The results of this study showed that smoking have a tendency to raise coronary heart disease occurrence in the respect of serum lipid levels and vitamin C, PUFA intake were significantly different.

The purpose of this study was to evaluate the effect of a weight control program on anthropometric values, serum lipid profiles and nutrient intakes. The subjects of this study were 38 obese children (boy : 17, girl : 21) with obesity index over 120%. The weight control program for obese children included nutritional education (50 min) and exercise (50 min) for 10 weeks. The nutrition intakes of the children were surveyed before and after the weight control program by 24hr recall test. The BMI, R$\ddot{o}$hrer Index, Obesity Index, WHR (Waist - Hip ratio) and body fat(%) were significantly decreased after completion of the weight control program. The total cholesterol and HDL-cholesterol of subjects were significantly increased after the weight control program. Distribution of serum lipid profiles was slightly changed. The energy intakes were significantly decreased (p < 0.001). from 1760.8 kcal to 1435.2 kcal. In addition, the intakes of P, Zn, retinol, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin were significantly decreased. while intakes of vitamin C and folate were increased. Calcium and folic acid were upper 25% of subjects, under EAR(Estimated Average Requirements) intake before the weight control program. The distribution of energy intakes was significantly changed into positive status; fat percentage was decreased 26.3% to 22.1% (p < 0.01). Carbohydrate was increased 58.6% to 61.2% (p < 0.05). Meal distribution of energy intakes was changed; calorie percentage from lunch significantly increased from 32.2% to 38.3%. Calorie percentage from snack significantly decreased from 17.7% to 13.5%. In conclusion, weight control program for 10 weeks is effective in obesity index and nutrient intakes although serum lipid values were a little changed.

Although intravenous fat emulsions are well accepted as a consituent of a total parenteral nutrition regimen it is still controversial how much it can be used and who to use it in consideration of physical situation of useres. In this study the effect of two marketed lipid formulas on serum lipids change was investigated. Each lipid formula was injected to twelve normal adult volunteers and a set of blood samples was drawn at 5 minute interval during the experiment. Changes of triglycerides. free fatty acids free glycerol total cholesterol and phospolipids in the serum wre determined. To calculate serum lipids clearance the phar-macokinetics of serum triglyceride fractional removal rate(k) and half-life time(t/2) were calculated using intravenous fat tolerance-test(IVFTT) None of the parameters determined in this experiment was statistically different between two marketed formulas. In summary the bolus injection of the lipid formulas did not produce any adverse effects and their elimination kinetics from the blood stream were similar.

There has been increasing research interests that green vegetables play beneficial roles in human health. This study was performed to investigate the effects of freeze-dried green vegetable extract of Angelica keiskei Koidz (A) and Brassica oleracea acephala (B) on lipid profiles and antioxidant status in rats. Seven-weeks old male Sprague Dawley rats were divided into 6 groups and fed diets containing 5% A & B and 0.5% cholesterol (cho) for 8 weeks [Control Diet (C) & C + chol (CC), A & A + chol (AC), B & B + chol (BC)]. Lipid profiles and antioxidant status were determined by enzyme assay methods. The serum levels of [LDL + VLDLJ-cholesterol of the rats fed vegetable extract diets A and B were significantly lower than that of group C and the ratios of HDL/[LDL + VLDL] were significantly higher in groups A and B. Addition of cholesterol in the diet, however, abolished this effect. The Brassica oleracea acephala juice lowered serum TG level even when cholesterol was added to the diet. Serum total antioxidant status(TAS) were significantly higher in groups A and B as compared to the control group and the ratios of [GSH-Px +Catalase]/total-SOD in the liver were also significantly higher in groups A and B indicating that H202 produced be efficiently removed. In conclusion, freeze-dried green vegetable extract diets (A and B) improved serum lipid profiles by increasing the HDL/[LDL + VLDL〕 ratio and exerted favorable influences on antioxidant systems by improving total antioxidant status (TAS) in serum and by significantly increasing the ratio of [GSH-Px + Catalase]/total-SOD in the liver.

This study was carried out to investigate effect of serum lipid and liver tissue in lectin from Viscum album on rats. The lectin was purified by sepharose 4B affinity chromatography and gel filtration using sephadex G-150 with plant material from Viscum album. After 72 h of $CCl_4$ injection, there was a significant increase in serum total cholesterol and triglycerige levels relative to the control group. However, treatment of both Viscum album and purified lectin were significantly decreased lipid parameters against the $CCl_4$-induced. Histological observation of the liver section of rats challenged with $CCl_4$ produced a marked increase of cytoplasmic vacuoles in number, while rats administered olive oil alone did not alter the normal hepatic architecture. Histological observation of the liver section in rats treated 72 h with either Viscum album purified lectin or $CCl_4$-induced liver lipogenesis showed decreased numbers of cytoplasmic vaculoes and necrotic cells. These results suggest that Viscum album lectin has a significantly decreased lipid in serum or histological observation of the liver section decreased in lipogenesis in rats.

This study was carried out to investigate the effect of Lentinus edodes which were harvested at different times of maturity on blood glucose and lipid levels in diabetic mice. The diabetic KK mice were fed diets supplemented with Lentinus edodes harvested early (LE) or late (LL) for eight weeks, and control (CO) mice were fed regular diet without Lentinus edodes. Diet intake, body weight, organ weight, blood glucose and serum lipid levels were measured. The mice which were fed diets supplemented with LE and LL showed significantly lower body weights compared to the CO group. There were no significant differences in the diet intake and the weights of different organs including liver, heart, kidneys, and epididymal fat pad among three different groups. Furthermore, the concentrations of serum triglycerides and total cholesterol were significantly lower in LE and LL groups compared to the CO group. These results clearly demonstrate that Lentinus edodes, regardless of their harvested period reduced body weight and serum lipid without affecting blood glucose level in diabetic mice.

In order to elucidate the effects of a lacto-ovo vegetarian diet on serum lipid levels, 91 male collegians residing in the Seoul area were recruited. The vegetarians did not smoke tobacco nor drink alcohol. Their anthropometric measurements, dietary intakes, and blood lipid concentrations were compared to age-matched omnivorous controls. The subjects were divided into four groups. The four groups were: 1) NSNDV (n=25): Non Smoking Non Drinking Vegetarians, 2) NSNDO (n=10): Non Smoking Non Drinking Omnivores, 3) SDO (n=37): Smoking, Drinking Omnivores, 4) SDM (n=11): Smoking Drinking Meat-eaters. Total serum cholesterol, HDL-cholesterol and hematocrit were analyzed. The results were as follows: Weight (p<0.05) and BMI (p<0.01) were significantly higher in SDM than NSNDV. Dietary protein (p<0.01), iron (p<0.05) and dietary lipids (p<0.01) from animals in NSNDV were significantly lower than the results in the SDM. Interestingly enough, we noted no significant differences between the four groups in terms of average total dietary protein, dietary lipids and dietary iron, total serum cholesterol, or HDL-cholesterol. Dietary fiber intake was significantly higher in NSNDV than in SDM (p<0.05). Weight, BMI, and total cholesterol were significantly positively correlated with animal protein (p<0.05) and animal lipid (p<0.01) intake. These results showed that vegetarian collegians who haven't smoked tobacco nor drunk alcohol evidenced lower body weight, BMI, and dietary animal lipid intake, but higher dietary fiber intake, than the other three groups. Additionally, intake of animal protein (p<0.001) and intake of animal lipids (p<0.001) were significantly positively correlated with body weight, BMI, and total serum cholesterol in male collegians.

This study was designed to investigate the effect of dietary vitamin E levels on lipid metabolism in caffeine-fed rats. Male Sprague-Dawley rats were fed on diet containing one of three levels of vitamin E(37.5, 750, or 1,500mg/kg diet0 which was with or without 0.3% caffeine. The rats were sacrificed after 5 and 10 weeks of the feed periods. Results obtained from this study were as follows ; Net weight gain, feed intake and FER in the caffeine added groups were significantly decreased as compared to those of only vitamin E fed group. Liver and kidney weights tended to increase in the caffeine added groups, but spleen and heart weights were not affected. Total lipid contents in serum and liver tended to decrease as dietary vitamin E became increasing and caffeine diet adding. Serum total cholesterol content tended to increase in the caffeine added group. But, liver cholesterol content were decreased. And the higher the dietary vitamin E level became, the lower serum and liver cholesterol contents were. Serum and liver triglyceride contents were significantly lower in the caffeine added groups than in the only vitamin E fed groups. The degree of decrease was more evident as dietary vitamin E level became more increasing. Serum aminotransferase activity was not affected in all experimental groups.
