The purpose of this study was to investigate the correlations among the anthropometry, serum lipid levels and nutrient intake in Korean female university students. The subjects were 119 female students at a university located in Incheon. This study was conducted using a self-administered questionnaire. Anthropometric data were measured and blood lipid levels were analyzed. Nutrient intake collected from 3 day-recalls was analyzed by the Computer Aided Nutritional Analysis Program. The data were analyzed by SPSS 10.0 program. Average age, height and weight of the subjects were 20.9 years, 160.1cm and 54.3kg, respectively. Average serum TG (triglyceride), total cholesterol, HDL-C (high density lipoprotein-cholesterol) and LDL-C (low density lipoprotein-cholesterol) levels of the subjects were 69.47mg/dl, 146.85 mg/dl, 50.49mg/dl and 82.52mg/dl, respectively. Average AI (atherogenic index) of the subjects was 2.03, which was in the normal range based on risk values. Average intake of most nutrients except protein, vitamin B$_1$, vitamin C and phosphorus were lower than the Korean RDA. Especially calcium and iron intakes of the subjects were under 65% of the Korean RDA. Serum TG, total cholesterol and LDL-C levels were negatively correlated with DBP (diastolic blood pressure). HDL-C/LDL-C and HDL-C/total cholesterol were positively correlated with height. Age was positively correlated with phosphorus intake. DBP of the subjects was positively correlated with calcium and iron intakes. Serum TG level was positively correlated with total cholesterol, HDL-C, LDL-C and AI, while negatively correlated with HDL-C/total cholesterol. Total cholesterol level was positively correlated with HDL-C, LDL-C and AI, while negatively correlated with HDL-C/LDL-C, HDL-C/total cholesterol. HDL-C level was positively correlated with LDL-C, HDL-C/LDL-C and HDL-C/total cholesterol, while negatively correlated with AI. LDL-C level was negatively correlated with HDL-C/LDL-C and HDL-C/total cholesterol, while positively correlated with AI HDL-C/LDL-C ratio was positively correlated with HDL-C/total cholesterol and AI. HDL-C/total cholesterol was negatively correlated with AI. Fat intake was positively correlated with total cholesterol, HDL-C level, and vitamin B$_2$ intake was positively correlated with TG, HDL-C/LDL-C. Therefore, nutrition education is necessary for female university students to promote the lipid profile and to optimize the nutritional status. (J Community Nutrition 4(3) : 151∼158, 2002)

Present review is built on base of research work on Ganoderma lucidum in our laboratory. A great deal of experimental evidence has suggested that the pharmacological activities of Ganoderma lucidum (Lingzhi) are related to anti-oxidative and free radical scavenging activity. The anti-oxidative and free radical scavenging effects of polysaccharides and triterpenoids isolated from Ganoderma lucidum in different oxidative injury models including tert-butylhydroperoxide (tBOOH)- damaged mice peritoneal macrophages, alloxan-induced diabetes, experimental liver injury models induced by carbon tetrachloride (CCl4), D-galactosamine (DGal) and Bacillus Calmette-Guerin (BCG) plus lipopolysaccharides (LPS) were investigated. It is also demonstrated that Lugu lingzhi, one of Ganoderma product, significantly inhibited LDL oxidation mediated by endothelial cells and decreased monocyte adhesion to endothelial cell (EC) induced by Oxidative low-density lipoprotein (ox-LDL) and advanced glycation endproducts (AGE). Lugulingzhi-treated serum could markedly inhibit the expression of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-l) induced by ox-LDL and AGE.

Low density lipoprotein (LOL) is the major cholesterol carrier in the blood stream. Also, LDL oxidation has been proposed as an important step in the formation of atherosclerotic lesion. Thus, protection of LDL from oxidation is needed to prevent or to retard the progression of atherosclerosis. In this study, 6-hydroxyeugenol was isolated from the methanolic extract of the Spiraea blumei and the sructure was elucidated by spectroscopic data analysis. (omitted)

Data are limited on biological mechanisms underlying the associations of sleep insufficiency with obesity and dyslipidemia. To explore these mechanisms, we investigated appetite-regulating hormones, stress-related hormones, and cardiometabolic indicators in association with sleep fragmentation, which is a type of sleep disorder. In an experimental study, we randomly allocated 40 Wistar male rats aged 7 weeks into four groups; rats with ad libitum sleep and ad libitum intake (Control), those exposed to sleep fragmentation (SF), those with diet restriction (DR), and those exposed to sleep fragmentation and diet restriction (SF+DR). Amongst them, 13-day chronic sleep fragmentation was applied to the SF and SF+DR groups while 50% reduction in chow intake was applied to the DR and SF+DR groups for 13 days. After these experiments, blood lipid and lipoprotein profiles, leptin, ghrelin, adiponectin, cortisol, epinephrine, and norepinephrine levels were compared among the four groups. In the results, the SF group showed the highest levels of serum ghrelin (P<0.001) and the lowest levels of serum adiponectin (P<0.01). All experimental groups showed higher levels of low density lipoprotein-cholesterol (LDL-C) than the Control (P<0.001). LDL-C levels and the ratio of LDL-C and high density lipoprotein-cholesterol were positively correlated with ghrelin levels (P<0.05) in the SF group, but not in the DR and SF+DR groups. In the SF group, the highest levels of serum free fatty acids were also observed and correlated with lower levels of serum adiponectin, which reflects insulin resistance (P<0.05). Based on these findings, we suggest that chronic sleep fragmentation may induce disturbances in lipid metabolism and appetite-regulating hormones independent of food intake, and these metabolic disturbances may be worse due to insulin resistance related to overeating, which is indicated by elevated ghrelin levels in sleep fragmentation. For persons with sleep insufficiency, anti-atherogenic dietary interventions may be recommended to prevent cardiovascular disease.

Objectives: To compare the metabolic indices, lipid profile, androgens, and prostate specific antigen between prostate cancer and BPH and between grades of prostate cancer in a cross-sectional study. Materials and Methods: The study enrolled 95 cases of prostate cancer and 95 cases of benign prostatic hyperplasia (BPH). Prostate gland volume was measured using transrectal ultrasound. We compared insulin, testosterone, dihydrotestosterone, prostate specific antigen levels and lipid profile between prostate cancer of different grades and BPH. Further, prostate cancer patients were classified into low grade and high grade. Unpaired t-test for normally distributed variables and Man-Whitney U test for non-normal variables were used to assess differences. Results: We found that prostate cancer patients had significantly higher levels of insulin, testosterone, PSA, cholesterol, triglycerides, low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL) in comparison to their BPH counterparts. Higher levels of these parameters also correlated with a higher grade of the disease. Conclusions: We conclude that higher levels of insulin, testosterone, PSA, and cholesterol correlate with a higher risk of prostate cancer, and also with a higher grade of the disease.

Objectives : This study was undertaken to determine the in vitro antioxidant activity of the extract of Chilgitang herb-acupuncture solution (CHAS). Methods : The radical scavenging capacity was tested by 2,2-diphenyl-1-picryl-hydrazyl (DPPH), hypoxanthine-xanthine oxidase system, DCFH-DA assay, nitric oxide and peroxynitrite generating system. In addition, antioxidant activity on copper and AAPH mediated human low-density lipoprotein (LDL) oxidation was measured by using TBARS assay and relative electrophoretic mobility assay. The amount of total phenolic compounds was assayed by the Folin-Ciocalteu method. Results : CHAS revealed a potent scavenging activity on DPPH radical(82%), superoxide anions(73%), hydroxyl radical(63%), nitric oxide (99%) and peroxynitrite (99%). Moreover, CHAS showed a strong inhibitory effect (59%) on $FeCl_2$-ascorbic acid induced lipid peroxidation of rat liver homogenate. CHAS also markedly inhibited copper(81%) and AAPH(56%)-mediated LDL oxidation, and effectively suppressed the electrophoretic mobility during exposure of human LDL to copper ions. CHAS (82 mg/g) contained higher concentration of total phenolic compounds than that of water extract (45 mg/g) obtained from Chilgitang. Conclusions : These results indicate that CHAS may protect against ROS- or RNS involved diseases, including cardiovascular diseases.

Body fat reducing and physical-activity enhancing effects, along with artherosclerosis improving effects, of conjugated linoleic acid (CLA) were elucidated on obese male middle school students with more than 30% body fat. Twenty-four volunteers were randomly divided into control (placebo, n=12) and CLA treatment (n=12) groups. Subjects were daily fed 6 g CLA (6 capsules, twice a day) or a placebo for 12 weeks. At the end of the experiment, body composition, blood lipid composition and exercise capacities of subjects were measured. CLA significantly reduced body fat content and body mass index (BMI) along with body weight, while the placebo did not have any such effects. Similarly, CLA significantly reduced low-density lipoprotein (LDL)-cholesterol, total cholesterol, and triglyceride, but elevated high-density lipoprotein (HDL)-cholesterol content in blood. Meanwhile, in terms of exercise capacity, there were significant enhancements of trunk flexion, closed-eyes foot balance, standing long jump, shuttle run, and sit-up activities in the CLA treatment group. These results indicate that CLA consumption reduced body fats, improved atherosclerosis factors in blood and improved physical activity of young male obese middle school students, and suggest that CLA could be a useful material for the heath care of obese young men.
