A cross-sectional study to determine dietary intake and plasma triglyceride total cholesterol LDL-cholesterol and HDL-cholesterol of 185K Korean men was conducted across three different age groups The younger group (age 21 to 34) was significantly (p<0.001) taller but showed lower (p<0.05) percent body fat than the older group (age 45 to 60) Weight and body mass index was not different among age groups. Older men showed significantly(p<0.01) lower energy and total fat intake than younger men Besides macronutrients, most participants consumed an adequate amount of micronutrients but calcium consumption of the middle age group (age 35 to 44) was less than 75% of RDA In older men plasma triglyceride(207.8$\pm$155.5 mg/dl) total cholesterol (201.4$\pm$40.0 mg/dl) and LDL-cholesterol(106.0$\pm$32.7 mg/dl) concentrations were significantly hight(p<0.001) than in younger men wereas no significant difference was observed in HDL-cholesterol concentration Subjects with a higher BMI(bMI$\geq$25.0) showed significantly higher (p<0.001) triglyceride(200.2$\pm$107.6 mg/dl) total cholesterol(211.0$\pm$40.1 mg/dl) LDC-cholesterol(118.16$\pm$35.5 mg/dl) concentrations and lower(p=0.001) HCL-cholesterol concentration (52.8$\pm$15.9 mg/dl) than subjects with lower BMI(BMI<23.0) Dietary intake of fat cholesterol did not show significant associations with any of the plasma lipid profiles. However, anima fat intake was significantly (p<0.05) correlated with plasma total cholesterol and triglyceride concentrations in the older age group. On the hand percent body fat was correlated (p<0.05) with all of the plasma lipid and lipoprotin concentrations examined for all age groups Results indicate both dietary intake and percent body fat are important determinants of the plasma lipid concentrations is the elderly but only percent body fat or body mass could be valid predictors for the plasma lipid concentrations of the younger age group.

Objectives: The purpose of this study was to examine the effects of fermented soybean on body weight, body fat, serum lipid profiles in obese women, especially specific to menopausal woman. Methods: Sixty healthy obese volunteers who visited ${\bigcirc}{\bigcirc}$ University Oriental Hospital from May 20th, 2014 to September 25th, 2014 took part in clinical trial. They divided into 2 groups, 30 volunteers allocated to fermented soybean and other 30 to placebo group. Body weight, BMI, waist and hip ratio, serum lipid were measured 3 times, and fat percentage, leptin, adiponectin were evaluated 2 times. Results: All 60 volunteers completed 12-week trial. 5 men were excluded, and 2 women against the clinical decision rule were excluded. In the end, 53 women were studied as clinical subjects. After 12 weeks intervention, there was no effects in comparison of group by time interaction. Without considering time interaction, there was a significant difference in triglyceride level between soybean group and placebo group (p=0.044). Treatment group were dividing by age 40, a group in age 40 or over 40, and other group aged below 40. There was a significant difference in group by time interaction of total cholesterol level, and without considering time interaction, there was a significant change in waist-hip ratio between groups. Conclusions: There were no effects on weight and body fat decrease in 12-week trial using fermented soybean as a supplement. But there were significant differences in triglyceride change between the treatment and placebo groups, also cholesterol and waist and hip ratio in soybean group divided by age 40. It seems that fermented soybean is effected on improving serum lipid profiles.

Drosophila melanogaster (fruits fly) is a representative model system widely used in biological studies because its brain function and basic cellular processes are similar to human beings. The whole head of the fly is often used to obtain the key function in brain-related diseases like degenerative brain diseases; however the biomolecular distribution of the head may be slightly different from that of a brain. Herein, lipid profiles of the head and dissected brain samples of Drosophila were studied using electrospray ionization-mass spectrometry (ESI-MS). According to the sample types, the detection of phospholipid ions was suppressed by triacylglycerol (TAG), or the specific phospholipid signals that are absent in the mass spectrum were measured. The lipid distribution was found to be different in the wild-type and the microRNA-14 deficiency model ($miR-14{\Delta}^1$) with abnormal lipid metabolism. A few phospholipids were also profiled by comparison of the head and the brain in two fly model systems. The mass spectra showed that the phospholipid distributions in the $miR-14{\Delta}^1$ model and the wild-type were different, and principal component analysis revealed a correlation between some phospholipids (phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatidylserine (PS)) in $miR-14{\Delta}^1$. The overall results suggested that brain-related lipids should be profiled using fly samples after dissection for more accurate analysis.

Antioxidant vitamin supplementation focuses one's attention on the prevention of age-related diseases. This study was conducted to investigate the antioxidant status and lipid profiles and to look into the antioxidant vitamin supplementation that affects lipid metabolism in 20 elderly non-smoking Korean women (placebo group: n = 6, vitC suppl: n = 7, vitE suppl: n = 7). Age, height, weight, muscle, percent of fat and WHR were not significantly different among the groups, however $\%$ of fat was above $33\%$ and WHR was above 0.9. And blood pressure of the placebo group was 131.7/81.7 (border line hypertension), that of vitamin C supplement was 141.4/87.1 (hypertension) and that of vitamin E supplement was 151.4/92.9 (hypertension). Although nutrient intakes of all groups were poor, antioxidant status (blood vitamins C, E, A, and beta-carotene) and lipid profile (TG, total-cholesterol, VLDL-cholesterol, LDL-cholesterol, HDL-cholesterol) were normal. For nutritional intervention, the vitamin C supplement group received L-ascorbic acid 1,000 mg, and vitamin E supplement group received d-alpha-tocopherol 400IU for 4 weeks, showing the effects of vitamin E supplementation. Response total cholesterol of HDL-cholesterol (T-Chol/HDL) in vitamin E supplement group was significantly decreased from 4.3 to 3.2. And response LDL-cholesterol of HDL-cholesterol (LDL/HDL) in the vitamin E supplement group was also significantly decreased from 2.6 to 1.7. In addition, after the adjustment for plasma lipids (TG, total cholesterol), plasma vitamin A levels in vitamin E supplement group were significantly increased from 7.89 mg/g to 14.91 mg/g. And systolic blood pressure in vitamin E supplement group was significantly reduced. These results suggested that vitamin E supplementation affects the lipid profiles and blood pressure in elderly non-smoking women. So various nutrition programs must be implemented against age-related diseases and further studies are needed regarding sorts and amounts of antioxidant nutrients and supplementation periods.

The aim of this study was to evaluate the effects of soyoligosaccharides on intestinal microflora transit time lipid profiles and immune responses. Forty-eight male rats of Sprague-Dawley strain were divided into six groups(SYS: soybean oil-sucrose SYO: soybean oil-oligo SES; esame oil-sucrose SEO:sesame oil-oligo BFS : beef tallow-sucrose BFO : beef tallow-oligo) soyoligo-groups(SYO, SEO, BEO) were fed the diet containing 5% soyoligosaccharides but control groups not fed them and all groups were fed 20% fats for 4 weeks. The number of fecal bifidobacteria tended to increase after soyoligosaccharides feeding. The significant increase was found in SEO group compared to SES in that of fecal bifidobacteria,. Stool wet weight dry fecal weight and stool water content were increased significantly in soyoligo-group(SYO, SEO, BFO) compared to control groups(SYS, SES, BFS) and gastrointestinal transit time(TT) tended to increase. Soyoligosaccharides lowered plasma cholesterol in SEO group significantly more than did other groups. soyoligo-groups(SYO, SEO, BFO) tended to decrease liver triglycerides compared to control groups. Plasma IgG concentration increased in beef tallow groups(BFS, BFO) than that in other dietary fat groups. Soyoligosaccharides and kinds of fats had effects on plasma C3 concentration and mitogenesis of the spleen cells. Soyoligosaccharides had no effects on plasma leptin and insulin concentration but kinds of fats did so that sesame groups were decreased significantly in plasma leptin concentration but increased significantly in plasma insulin concentration compared to other dietary fat groups. In conclusion dietary soyoligosaccharides changed the composition of the intestinal microflora beneficially with sesame oil and partially had effect on plasma and liver lipid profiles .(Korean J Nutrition 33(6) : 597∼612, 2000)

In this study, the effects of corn peptide consumption on plasma lipid profiles were investigated in high cholesterol diet-fed rats. Male Sprague-Dawley rats (n = 21) were fed with corn peptide-free (control) diet, diets containing 2% or 5% com peptide for 5 weeks. Hypercholesterolemia was induced by adding l% cholesterol and 0.5% cholic acid to all diets. No difference was found in food intake and body weight gain among groups. The corn peptide treated groups showed significant improvement in the plasma level of HDL-cholesterol (p<0.05) compared to the control group, while the plasma total cholesterol and LDL-cholesterol were not affected.5oio corn peptide supplemented diet reduced plasma level of triglycerides (p<0.05) The atherogenic index was decreased in the corn peptide treated groups. These results suggest that consumption of corn peptide may lead to an amelioration of metabolic syndrome as well as a reduction of cardiovascular disease and hyperlipidemia through increasing the level of HDL-cholesterol, and decreasing the level of triglycerides in plasma.

There is growing evidence that soy isoflavones play beneficial role in the prevention of cardiovascular disease. However, current data are not sufficient to determine the effective dose of isoflavone on improving plasma lipid profiles and total antioxidant capacity in Korean menopausal women. In the present study, 24 perimenopausal and 23 postmenopausal women were divided into 3 groups and were given soy isoflavone supplements of 100, 150, 200mg/day for 12weeks. Blood samples were taken before and after 6, 12weeks of soy isoflavone supplementation for analysis of total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride and total antioxidant status(TAS). In the perimenopausal women, serum total cholesterol level decreased significantly in all three groups after 12weeks of isoflavone supplementation(p< 0.05). However, serum LDL cholesterol level significantly lowered only in 150 and 200mg groups, and serum triglyceride level decreased significantly in 200mg group(p<0.05). In the postmenopausal women, the 150mg isoflavone supplementation group demonstrated significant effects on lowering serum total cholesterol, LDL cholesterol levels and raising HDL cholesterol level after 12weeks of isoflavone supplementation(p<0.05). Two hundred mg isoflavone supplementation group had a significantly higher TAS than other groups in both perimenopausal and postmenopausal women. (Korean J Nutrition 34(3) : 322∼329, 2001)

It is known that onion increases antioxidative and antibiotic capacity, and decreases blood pressure and cholesterol levels. The study was carried out to investigate whether ethanol extract of onion can enhance blood lipid profiles in hypercholesterolemic patients. Foully three hypercholesterolemic patients were randomly divided into 2 groups; 25 in controls and 18 in experimental group. The control group was offered to take placebo for 4 weeks (200 ml/day), and experimental group was offered to consume ethanol extract of onion for 8 weeks (200 ml/day that corresponds to 500 g of onion). There were no differences in sex, age, body mass index (BMI) and educational levels between groups before treatment. After 8 weeks of onion extract consumption, plasma triglycerides level was significantly decreased in experimental group compared to control (p<0.05). Total cholesterol level was tended to decrease in experimental group, but there was no significant difference of change between control and experimental group. The levels of plasma glucose and LDL-cholesterol were not changed significantly after onion extract consumption. In summary, alcohol extract of onion may have a positive effect on the lipid profiles of hypercholesterolemia patients through decreasing plasma triglyceride concentration.

Korean red ginseng (KRG) has been shown to enhance endothelium-dependent vasorelaxation in experimental animals; however, little is known about its pharmacological effects on vascular stiffness in patients with coronary artery disease (CAD). This randomized, double-blind, placebo-controlled crossover trial was carried out to determine whether KRG has beneficial effects on arterial stiffness, cardiovascular risk factors such as plasma lipid profiles and blood pressure (BP), and Rho-associated kinase (ROCK) activity. Twenty patients (mean age, 62.5 years) with stable angina pectoris were given KRG (2.7 g/day) and a placebo alternatively for 10 weeks. Blood biochemical analysis and pulse wave velocity (PWV) recording were performed on day 0 and after the completion of each treatment. ROCK activity was assessed based on the level of phospho-$Thr^{853}$ in the myosin-binding subunit of myosin light chain phosphatase, determined by Western blot analysis of peripheral blood mononuclear cells. KRG significantly decreased the systolic BP, brachial ankle PWV, and heart femoral PWV in the patients (all p<0.05), but did not significantly alter the serum lipid profiles, including triglycerides and total, high-density lipoprotein, and low-density lipoprotein cholesterol levels. The ROCK activity tended to decrease (p=0.068) following KRG treatment. The placebo did not significantly alter any of the variables. In conclusion, KRG decreased systolic BP and arterial stiffness, probably via the inhibition of ROCK activity, in patients with CAD, but had a neutral effect on serum lipid profiles. Our data suggest that KRG has a therapeutic effect on CAD.

The purpose of this study was to compare the nutrient intake, dietary habits and serum lipid profiles of smoking male college students to those of non-smoking subjects. The subjects were composed of two group: 111 smokers and 120 non-smokers was used along with a questionnaire. Anthropometric measure, dietary intakes using 24-hours recall method were compared. The average ages of smokers and non-smokers were 21.6 and 21.1 years old, respectively. The height, weight and BMI of smokers and non-smokers were no significant difference. The average numbers of smoked cigarettes were 15.9/d and the average packyear was 4.9 in the smokers. About 92.8% of the smokers drank alcoholic beverages, while 72.5% of the non-smokers did. The smokers tended to eat less breakfast meal, but drink coffee more often compared to the non-smokers. The mean daily energy and food intake were 2,135.8 kcal and 1,169.5 g in the smokers and 2,034.3 kcal and 1,229.4 g in the non-smokers. The smokers consumed significantly higher intake of fat. The serum triglyceride level of the smokers was significantly higher than that of the non-smokers. In conclusion, the smokers of this study showed a more undesirable dietary intake in the light of their high Int an alcoholic beverages, and coffee. Therefore, it could be suggested that more systematic research be conducted with respect to serum triglyceride and smoking and that increased nutrition education and guidelines for smokers are required.
