The purpose of this study was to obtain the serum lipid levels according to the lifestyles, and examine the influence of lifestyles on the serum lipid levels among adults who examined the health checkup in an university hospital. The subjects for this study were 4,112 adults who underwent medical examinations at the health center of a university hospital in Daejeon city from Jan 2012 to Dec 2013. The lifestyles and serum lipid levels of study subjects were obtained from self-recorded questionnaires and medical examination charts of the hospital. As a result, the mean values of the serum lipid levels (TC, HDL-C. LDL-C and TG) and atherogenic index (AI) of the study subjects showed a significantly difference according to the lifestyle, such as age, alcohol consumption, smoking, regular exercise, overeating and meat consumption in both sexes. The TC, HDL-C. LDL-C, TG and AI showed a positive correlation with age, AUDIT score, but the HPI score showed a negative correlation in both sexes. In the age-adjusted odds ratio, the risk ratio of an abnormality of TC, HDL-C. LDL-C, TG and AI increased significantly because there was an increase in the group of everyday overeating and meat consumption, smoking group, no exercise group, and low HPI group than their respective counterparts in both sexes. The above results suggested that the serum lipid levels of the subjects was closely related to increasing age, and lifestyles, such as alcohol consumption, smoking, regular exercise, overeating, and meat consumption.

Objectives: This study is designed to investigate the effects of Banhahubak-Tang Extract (BHTe) on stress. Methos: BHTe was fed to ICR male mice ($20{\pm}2g$) orally with the dose of 100 mg/kg/day for five days. Mice were then exposed to sociopsychological stress by observing foot shock stressed mice for one hour for five days while restrained. Results: 1) The BHTe-administered group showed a tendency of decreasing of serum corticosterone secretion compared with the control group. 2) The BHTe-administered group showed an increase in noradrenalin secretions in the dorsal cortex of the brain, but it was not significant. 3) BHTe administration had no effect on the brain level of lipid peroxidation. 4) BHTe administration decreased the serum level of lipid peroxidation. 5) BHTe administration decreased the Cu,Zn-SOD in the brain. 6) BHTe administration had no effect on catalase activity in the brain. 7) BHTe administration had no effect on the brain level of GSH. 8) BHTe administration increased the serum level of DPPH free radical scavenging activity, but not significantly enough to make a comparison with BHT. 9) The elevated plus-maze test is designed to detect the effect of anxiolytic drugs. The BHTe group showed a significant increase in latency time. Conclusions: These results suggest that BHTe can effectively rid the subject of the effects of sociopsychological stress.

A feeding trial was carried out to Investigate the effect of lipid level and herb mixture in the diets on growth of juvenile parrot fish, Oplegnathus fasciatus. Two plicate groups of fish averaging 4.5 g were fed four experimental diets containing herb mixture (0 and 5 g/kg diet) at each of two lipid levels $(8\%\;and\;16\%)$ for 8 months from summer to spring (water temperature, $7.2-25.4^{\circ}C)$. Weight gain improved with increasing dietary lipid level or supplementation of herb mixture during the first 4 months feeding period. Weight gain of fish fed the diet containing $16\%$ lipid level was significantly higher (P<0.05) than that of fish fed the diet containing $8\%$ lipid level. Weight gain of fish fed the diet with herb mixture was significantly higher (P<0.05) than that of fish fed the diet without herb at the $16\%$ lipid level. Feed efficiency was influenced by dietary lipid level or herb mixture during the first 4 months. On the other hand, weight gain and feed efficiency were not affected by dietary lipid level and herb mixture after 4 months until end of feeing period. Survival of fish fed the diet containing $8\%$ lipid without supplementation of herb mixture was the lowest among the groups (P<0.05). Lipid contents of liver and viscera tended to increase with increasing dietary lipid level during the first 4 months feeding period, however muscle lipid content was not influenced by dietary lipid and herb. Total cholesterol of serum was influenced by dietary lipid level during the first 4 months feeding period. These results indicate that an increase of dietary lipid level from $8\%\;to\;16\%$ and supplementation of herb mixture can improve growth performance of juvenile parrot fish when water temperature is optimum for growth such as the summer season in Korea.

This study was performed to investigate the effects of the chitosan oligosaccharide administration on the improvement of the lipid compositions, blood glucose and enzyme activities in the serum of hypercholesterolemic rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride (TG), phospholipid (PL) and blood glucose in serum were higher in the hypercholesterolemic group (group CW) and cholesterol+chitosan oligosaccharide administration group (group CCW) than those in the control group (group BW, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG, PL and blood glucose in serum were lower in the group CCW than those in the CW, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the group CCW were higher than in the group CW. The activities of alkaline phosphatase (ALP) and aminotransferase (AST, ALT) in serum were lower in the group CCW than in the hypercholesterolemic group CW. From the above results, it was suggested that chitosan oligosaccharide administration was effective in the prevention and improvement of the lipid level, blood glucose and enzyme activities in serum of hypercholesterolemic rats.

In this study, in an attempt to elucidate the relevance and the association between AUDIT level and health related indices such as obesity-related indices (BMI, waist circumference, body fat percentage), serum liver-enzyme levels (AST, ALT, GGT, total bilirubin) and serum lipid levels (TC, TG, HDL-C, LDL-C), data about including results of health checkup examination and questionnaire from 558 male examinees of 30-79 years old, who received a comprehensive health examination in the health promotion center of a university hospital during the period of January 1 to December 31, 2012, was analysed. As a results, the distribution of AUDIT rating of subjects was Zone I 58.2%, Zone II 25.3%, Zone III 7.0%, and Zone IV 9.5%. And AUDIT levels have significant relevance with age, smoking, body fat, GGT and TG. Especially, for the waist circumference, GGT and TG, the odds ratio indicating abnormality significantly increased in the higher AUDIT groups (Zone II~Zone IV) than a low-grade group (Zone I). This suggests that drinking problem with a high AUDIT level has a significant relevance with an abnormal increase of indices for obesity, serum liver-enzyme levels, serum lipid levels.

This study was performed to investigate the effects of dietary fibers from tangerine peels on lipid and cadmium metabolism. And effects were compared with those of commercial dietary fibers($\alpha$-cellulose, citrus pectin). Sixty male rats of Sprague-Dawley strain weighing 186.7$\pm$2.6g were blocked into 12 groups according to body weight, and were raised for 2 weeks. Cadmium chloride was given at the levels of 0 of 400 ppm in diet. Various dietary fibers were given at the level of 0 or 4%(w/w) of diet. The results are summarized as follow. In lipid metabolism, insoluble fibers[insoluble dietary fibers from tangerine peels(IDE), $\alpha$-celluolse] increased fecal excretion of lipids by inhcreasing feces weight, and decreased the concentrations of serum triglyceride and liver lipids. Soluble dietary fibers from tangerine peels(SDF) decreased the concentrations of serum cholesterol and liver lipids by increasing fecal lipids, too. In cadmium metabolism, soluble fivers(SDF, pectin) inhibited Cd absorption by increasing fecal Cd excretion and decreased Cd concentrations of intestion, liver and kidney. In conclusion, among the extracted fibers, SDF were more effective on lipid and Cd lowering activity and IDF had effect of increasing fecal lipid excretion. This result is useful to reduce food waste and utilize waste products.

This study was to investigate the effects of chitin, chitosan , NOCC and cellulose on cadmium toxicity and lipid metabolism in rats. Fifty male rats of Sprague-Dawley strain weighing 155$\pm$17g were divided into 10 groups according to body weight, and were raised for 5 weeks. Levels of 0 and 400 ppm of cadmium chloride were in the diets. And chitin, chitosan , NOCC and cellulose were given at the level of 0 and 4%(w/w) of the diets. Chitosan and NOCC decreased Cd concentration of liver and kidney, and increased the fecal excretion of Cd. Although cellulose was less effective, cellulose also decreased Cd concentration of liver and increased fecal Cd excretion . However chitin had little effect on alleviating Cd toxicity. In addition, chitosan and NOCC lowered total lipid, cholesterol and triglyceride contents in serum and liver by decreasing the lipid absorption. The lowering of cholesterol especially had a remarkable effect. Although it was less effective than chitosan and NOCC, chitin decreased the lipid absorption ratio and lowered cholesterol contents in serum and liver. In conclusion , chitosan and NOCC showed effects of decreasing the absorption of Cd and lipid.

The purpose of this study was to investigate the relationship among nutritional status, serum lipids and leptin of 134 elementary school students with different obesity index residing in Kyunggi-do, Korea. Subjects were assigned to under weight, normal weight or over weight group according to the their obesity index. Their nutritional status, serum lipid and leptin levels were evaluated based on 24-hr dietary recalls, anthropometric measurements and blood analysis. The mean weight, height and obesity index of total subjects was 150.8cm, 45.6kg and 5.4%. The mean % of body fat was higher while LBM and TBW (total body water) were lower in over weight subjects than those of other two groups. Total food, plant protein, carbohydrate, and vitamin C intakes of underweight male students were lower than those of overweight male students. The consumption of total fat was the highest in the female normal weight subjects and the lowest in female overweight subjects. Male students consumed more plant protein and vitamin C than female students. The mean daily intake of vitamin B$_2$, calcium and zinc of all subjects did not meet the Korean RDA. Also, iron intake of female students was lower than the Korean RDA. The mean level of serum leptin was the highest in male and female overweight subjects (p＜0.001). The HDL-cholesterol level was the highest in the underweight group of male subjects (p＜0.05) and in the normal weight group of female subjects (p＜0.001) The serum level of leptin and atherogenic index (AI) of females were higher than those of males. Serum leptin of total subjects had significantly positive correlation with obesity index, weight, SBP, body fat, cholesterol intake, serum triglyceride, and AI. However, serum leptin was negatively correlated with LBM, TBW, intake of plant protein, vitamin B$_1$, vitamin C and serum HDL-cholesterol. Obesity index was also positively correlated with weight, SBP, body fat, serum triglyceride and AI. To summarize the results, the vitamin B$_2$, calcium, zinc, iron and fiber intakes should be supplied to elementary school students, especially those who were overweight. The average serum leptin level of students showed remarkably positive correlation with obesity index, body fat, serum lipids and AI. Also, it was suggested that the serum leptin might be related to the dietary factors like cholesterol, plant protein, vitamin B$_1$ and vitamin C of elementary school students.
