This study was performed to investigate the effect of Lycii fructus beer on serum lipid profiles and antioxidant activity in rat Sprague-Dawley (SD) rats weighting about 190g were divided into the following 5 groups ; distillate water (Control), 5% ethanol in distillate water (Ethanol), commercial beer (CB), Lycii fructus beer (LFB) and 5% alcohol red wine diluted with distillate water (RW). Body weight, total food intake, FER and percent organ (liver, kidney) weight per body weight were not significantly changed by Lycii fructus beer drinking. After 6 weeks, serum total cholesterol, triglyceride and HDL cholesterol level were not significantly different. But, Lycii fructus beer intake tended to decrease serum triglyceride level and atherogenic index. Also, GOT and GPT levels were expressed lower than Ethanol group. There was not significantly different in hepatic glutatiione (GSH) content and glutathione-S-transferase (GST) activities among 5 groups. Lipid peroxidation in the hepatic was decreased by Lycii fructus beer intake. The results demonstrated that Lycii fructus beer was potential and effective antioxidant that can protect the decrease associated with alcohol.

The serum levels of antioxidant materials (${\alpha}$-carotene, ${\beta}$-carotene, ${\beta}$-cryptoxanthin, lutein, lycopene, ${\alpha}$-tocopherol, ${\gamma}$-tocopherol, retinol) of the healthy Korean middle-aged adults (n = 373) were measured and their relationships with the serum lipids and anthropometric indices were analyzed. The serum levels of ${\beta}$-cryptoxanthin, ${\beta}$-carotene, lutein were higher than those of lycopene and ${\alpha}$-carotene. The levels of all measured carotenoids except lutein were significantly higher in females than in males, but retinol level was vice versa. There was a tendency of increase in serum levels of antioxidant vitamins with increasing age. The serum carotenoid levels had a positive correlation with serum cholesterol and a negative correlation with serum triglyceride. The serum levels of tocopherols or retinol showed a significantly positive relationship with blood cholesterol or triglyceride. In overall, anthropometric indices showed negative relations with serum carotenoids levels, but vice versa with serum tocopherol or retinol levels. Particularly, ${\beta}$-carotene and lutein levels showed a significantly negative relation with blood pressure in male subjects. The serum levels of ${\alpha}$-carotene, ${\beta}$-carotene and ${\beta}$-cryptoxanthin had significantly negative relations with body fat-related indices in female subjects. The results demonstrated that blood antioxidants levels differed by sex and age, and had significant relations with blood lipid levels and anthropometric indices. Therefore, the rationale and significance of the relationships need to be elucidated in the future study related to dietary intakes and life style.

The purpose of this study was to confirm that calcium intake and healthy status play a role in reducing the risk of cardiovascular disease, to assure that calcium intake and regular exercise are important in reducing serum lipid levels in middle-aged women. Daily nutrient intakes were analyzed by convenient method. Anthropometric measurement such as body weight and height and blood pressure were measured. The subjects divided into two groups : women in group I under 50 years of age($\leq$49 yr group) and those in group II 50 years up($\geq$50 yr group). Average ages of group I and II were 43.87 and 53.46 years. The nutrients intake of subjects were higher than Korean recommended dietary allowances(KRDA) except calorie, iron, calcium, vitamin B1. They showed significant difference each other in vitamin B2(p<0.05), calcium(p<0.01) intake. Mean daily calcium intake was 540.88mg in $\leq$49 yr group and 519.50mg in $\geq$50 yr group. The levels of serum cholesterol, triglyceride, blood pressure, Atherogenic Index(AI), LDL/HDL and Cardiac Index(CI) were increased with age. The triglyceride and total cholesterol concentrations and LDL/HDL in $\geq$50 yr group were significantly higher than those of $\leq$49 yr group. There was a highly significantly positive correlation between age and triglyceride, total cholesterol and Atherogenic Index(AI). Triglyceride, total cholesterol, LDL-cholesterol concentration and Atherogenic Index(AI) were positively correlated with body weight and WHR(waist-hip ratio). Also ther was a significantly negative correlation between exercise and Cardiac Index(CI). Also a significantly negative correlation was found between Ca intake and LDL-cholesterol. Exercise and Cardiac Index(CI) also had a significantly negative relation. The results suggest that increased habitual physical activity and calcium intake should be recommended as a way of decreasing blood lipids and blood pressure in middle-aged women.

Cigarette smoking has long been recognized as a major risk factor in the development of coronary heart disease. Several investigators have reported the strong association between smoking and high serum cholesterol, triglyceride concentration, SFA and low HDL cholesterol, PUFA and $\omega$6 concentrations. Therefore, this study was done to investigate the effect of smoking on the serum lipid profile and fatty acid composition of college women. Sixty-one non-smokers and twenty-seven smokers were selected from college women students in the Seoul area. Their lipid intake, serum lipid concentration and fatty acid composition were examined. There were no differences in the general characteristics and anthropometric indices between the smokers and non-smokers. However, alcohol consumption was significantly higher in smokers than non-smokers (p<0.001). The daily caloric intake of smokers and non-smokers were 1875.84 kcal and 1915.53 kacl, respectively. On the other hand, the mean daily intake of lipids and cholesterol were significantly lower in smokers (p<0.05). In smokers, the mean concentrations of serum total cholesterol, LDL-cholesterol and the LDL-C/HDL-C ratio were higher, and the compositions of EPA and DHA were lowe than in non-smokers. There was a negative correlation between the serum triglyceride and PUFA levels in the two groups. Also, serum HDL-C correlated negatively with MUFA in smokers and non-smokers (p<0.01). These results suggest that smoking cause inadequate changes in serum lipid profile and serum fatty acid composition, thereby increasing the tendency for coronary heart disease.

This experimental study was designed to investigate the inhibitory effects of hot water extract of Yukeuigambi-tang (YEGT) on high-fat diet-induced obesity and hyperlipidemia in C57BL/6 mice. Animals were divided into normal, control, YEGT(sample A 3.8 g/kg, and sample B 7.6 g/kg) treated group. Obesity with hyperlipidemia was induced by high fat diet treatment for 6 weeks. YEGT was given to the animals by oral gavage. The effect of YEGT on the body weight change, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, and leptin levels in serum were evaluated. In respect to the body weight change, sample B significantly reduced body weight compared with control group in the 6th weeks. In the total cholesterol, triglyceride, and leptin level, sample B significantly reduced all of them compared with control group; sample A significantly reduced triglyceride and leptin levels compared with control group. The above results suggest that YEGT is effective to prevention and treatment of obesity and hyperlipidemia.

We previously demonstrated that water-soluble egg yolk extract is not related to elevation of serum immunoglobulin E, which can initiate allergic reactions; however, it increases the level of high density lipoprotein (HDL)-cholesterol and the activity of B lymphocytes. In this study, egg white (EW) was fed to BALB/c mice to determine its influence on growth efficiency, immune modulation, and changes in serum lipid levels. A total of 50 five-wk-old BALB/c male mice were divided into 5 groups, 4 of which were fed 0, 10, 50, or 100 mg/d EW for 4 wk. Mice with an uptake of 10, 50 and 100 mg/d EW showed no significant changes in daily weight gain, feed efficiency rate, or populations of white blood cells. However, the activities of both B and T lymphocytes were significantly increased in all three EW groups at the final week of treatment. Interestingly, serum levels immunoglobulin E were not altered by EW consumption, but the IgG level was significantly increased in the 100 mg/d EW group. Serum lipid profile analyses showed no significant changes in total cholesterol, HDL, low density lipoprotein, or triglyceride levels by EW consumption. Taken together, these data demonstrate that consumption of EW promotes immune cell activities and the upregulation of serum IgG levels. However, we found no changes in serum lipid profiles and IgE levels. Therefore, our study suggests that consumption of EW might not be related to the risk of food allergy, but could be an excellent candidate for the maintenance of physiological homeostasis.

The effect of lxeris sonchifolia H.(godulbaegi) on lipid metabolism were studied in S. D. rats. Twenty four rats were divided into four groups and fed diets containing 1 % cholesterol, 0.25% sodium cholate, 10% coconut oil and 5% lard(control group)f for 3 weeks. An experimental diet group was added with 5% leaf(PL group) or root powder(PR group) of godulbaegi. The lipid components and enzyme activites of serum and liver were assayed. The concentrations of total cholesterol, triglyceride and phospholipid were significantly lower in the PL and PR groups than in the control group. The levels of HDL-cholesterol were not significant but showed somewhat higher values in the PL and PR groups compaired with the control. The activities of glutamic oxaloacetic transminase(GPT) and glutamic pyruvic transaminase(GPT) were significantly lower in the PL and PR groups compaired with the control. In view of these results Godulbaegi is expected to be an effective food in preventing and improving the hyperlipidemic state.

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.

We have studied the effects of buckwheat diet on serum glucose and lipid metabolism in 9 NIDDM volunteers during 2 weeks. The subjects were given dietary counseling in their own homes at 2-3 day intervals throughout experimental periods and the dietary intake were determined by interview and record methods. The intake of calorie, carbohydrate, protein and fat during the buckwheat diet period were not significantly different compared with control diet and body weight was maintained within 1-2kg. The mean total glycohemoglobin, fructosamine, total cholesterol and LDL-cholesterol levels at the end of buckwheat diet were significantly lower than the end of control diet (P<0.05). Fasting serum glucose, insulin and HDL-chloesterol levels were slightly decreased. The mean triglyceride level was increased but it was not significant. These results indicate that buckwheat diet is an effective therapeutic regimen for the control of metabolic derangements in diabetes mellitus.
