This study was carried out to examine the effects of alcohol on serum lipid levels. Subjects of this study were 50 military officers living in Honsung, Korea, 25 of whom consumed alcohol on a regular basis and 25 of whom did not. All subjects were previously informed of the purpose of the study and the methods of food intake reporting and blood testing. The age distribution range of subjects was 30-49 years. Weight, height, and body mass index(BMI) were not significantly different between the two groups. Blood pressure was compared, and it was found that the drinker group had mean systolic(SBP) and diastolic blood pressures(DBP) 10mmHg higher than the non-drinker group. Nutrient intake levels of the two groups were not significantly different and were adequate with respect to the recommended dietary allowances. It was found that the drinker group ingested more calories, protein, fat and vitamn B1 than the non-drinker group, while the non-drinker group ingested more carbohydrate, calcium, iron, vitamin A, niacin and ascorbic acid. These differences were believed caused by increased caloric intake from alcohol and additional intake of meat served with drinks for the drinking group. Fourteen of the twenty-five drinkers(56%) had drank regularly for five to ten years. Most drinkers drank 2-3 times per week, with alcohol intake less than two bottles(720ml)of distilled liquor(Soju) at a time. Meat was often served with alcohol as reported by 72% of the drinker group, and was believed to contribute to raised intake of calories, protein and fat in this group. Serum lipid levels of both groups were classified as normal, but the components of total cholesterol, triglycerides were significantly higher in drinkers than non-drinkers. The correlation between triglyceride levels and alcohol intake at one sitting was shown to be significantly positive(r=0.57, p<0.01), so it was believed that triglyceride elevation was associated more with heavy drinking than light drinking. We can conclude that if alcohol is consumed with a normal diet, then serum cholesterol, triglyceride and total lipid levels are expected to increase.

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.

The aim of this study was to evaluate the effect of kale (Brassica oleracea acephala) juice supplementation on serum lipid levels and phospholipid (PL) fatty acid compositions in hypercholesterolemic men. Thirty-two men with hypercholesterolemia (>200 mg/dl) were recruited among the faculty and staff at Y University after annual health examinations. The subjects consumed 150 ml of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed before and after supplementation, respectively, to ensure that the subjects maintained their usual diet and lifestyle throughout the intervention. Serum concentrations of HDL-cholesterol and the ratio of HDL-cholesterol to LDL-cholesterol were significantly increased (p<0.001) after intervention. Serum LDL-cholesterol concentration and atherogenic index were significantly reduced (p<0.001). Levels of 12:0, 14:0, $18:1{\omega}9$, $18:3{\omega}6$, and sum of monounsaturated fatty acids (MUFA) in serum pholspholipid (PL) were significantly increased, while $22:4{\omega}6$ level was significantly reduced (p<0.05). It can be speculated that kale juice, containing large amounts of antioxidant nutrients, contributes to changes of serum-PL-fatty acid compositions and the improvements of serum lipid profiles. This study demonstrates the supplementation of regular meals with kale juice may favorably affect serum lipid profiles and serum-PL fatty acid compositions and, hence, could lower the risks of coronary artery disease in men with hypercholesterolemia.

Mugwort has been used as a Korean folk medicine in treating liver diseases acting as an analgesics, sedative, diuresis, choleretics. This study was perfomed to evaluate the effect of mugwort extracts on the changes of enzyme activities, lipid accumulation of the serum and liver, when hepatotoxicity was induced by benzo(a)pyrene. The results are as follows: 1. Mugwort water extract administration prevented the increase of serum and liver AST, ALT, LDH, ${\gamma}$-GTP, liver ALP activities and bilirubin content caused by B(a)P injection. 2. The increase of serum and liver ALT, LDH, ${\gamma}$-GTP, serum AST activities and liver bilirubin contents in B(a)P treated group were decreased by mugwort methanol extract treatment. 3. Serum and liver total cholesterol, phospholipid, triglyceride level and serum HDL-cholesterol level were increased by B(a)P treatment. After combined treatment of mugwort water and methanul extracts, these lipid content were significantly decreased. 4. The hepatotropic effect of mugwort water extract and after-treatment against B(a)P induced hepatotoxicity was superior to that of methanol extract and pretreatment.

The experiments were performed to investigate the effects of protein and protein hydrolysates on lipid metabolism in the hyperlipidemic/hypercholesterolemic rat model induced by feeding fat-enriched diet. In Except 1 male rats were fed four semi-purified high fat and cholesterol diets that contained different nitrogen source, casein(C), casein hydrolysate(CH), corn gluten(G) and corn gluten hydrolysate(GH), for 6 weeks. In Expt. 2 rats were fed high fat and cholesterol diet for 4 weeks to induce hyperlipidemia and hypercholesterolemia. Then the rats were divided into 4 groups and were fed the four kinds of above experimental diets for 4 weeks consecutively. The contents of total lipid , cholesterol and triglyceride in blood, liver and feces were determined. Serum lipid concentrations of CH, G and GH were significantly lower than that of C. Serum cholesterol concentrations of hydrolysate groups(CH and GH) were significantly lower than those of intact protein groups(C and G). Serum HDL -cholesterol concentration tended to increase by hydrolysate intake. The total lipid, cholesterol contents in liver showed similarity results as above. Fecal lipid excretions of CH, G, and GH groups were significantly higher than that of C group. These results indicate that hypolipidemic and /or hypocholesterolemic effect of corn gluten or protein hydrolysates were detected in the process of inducing hyperlipidemia by high-fat and cholesterol diet or after inducing hyperlipidemia.

This study was performed to observe the effects of dietary fat levels and sources on lipids contents and cellularities of liver, brain, and adipose tissue of early weaned rats. Male Sprague-Dawley rats were prematurely weaned from postnatal 17th day with the experimental diets differ in fat levels : low(5%), medium(10%), high(20%) and fat sources : butter, soybean oil, butter＋ soybean oil. On the postnatal 29th day, contents of total lipid, triglyceride, cholesterol and phospholipid of serum, liver, brain and adipose tissue were determined, and DNA was determined to assess the cell growth. Rats early weaned fed high fat diet showed lower total lipid and triglyceride levels in serum and liver than those fed medium or low fat diet Rats early weaned fed high fat diet had adipocytes of fewer number, but larger size than those of rats fed low or medium fat diets. Rats early weaned fed soybean oil diet had more adipocytes thu those fed butter diet. Rats normally weaned to commercial chow diet showed lower total lipid, triglyceride, and cholesterol levels in serum and liver, had fewer adipocytes than all early weaned rats except for rats fed high fat-butter diet. These results suggest that high fat-butter diet is ideal weaning diet at early weaning.

This study was performed to investigate the effect of various levels of Zn(0, 30, 3000 ppms) and different kinds of lipid(corn oil, sesame oil or butter.) in the diet upon lipid metabolism and Zn & Cu concentration in various organs and tissues in weanling rats. The results obtained were summarized as following : 1) Food consumptions, body weight gains and F.E.R.s showed no significant differences among groups. 2) The contents of total lipids and total cholesterols in serum tended to increase with increase in lipid saturation and Zn levels. Those in per g liver were higher in butter groups and tended to be higher in low Zn groups. Total lipids contents in per g muscle tended to be higher in butter and high Zn groups, but total cholesterols contents in per g muscle tended to be higher in corn oil and low Zn groups. 3) Liver, serum and fecal Zn concentrations tended to be higher in high Zn groups than other Zn groups. The Cu concentrations in liver and serum tended to be lower in high Zn groups. On the contrary, the Cu concentrations in urine tended to be higher in high Zn groups.

Objectives : This study investigated neuroprotective effects of Polygoni Multiflori Radix on cerebral ischemia of hyperlipidemic rats. Methods : Effects of Polygoni Multiflori Radix were evaluated with changes of infarct size after He focal cerebral ischemia induced by the middle cerebral artery occlusion, changes of pyramidal neurons and expressions of Bax and Bcl-2 apoptosis regulating factors after global cerebral ischemia, and changes of serum lipid revels after cerebral ischemia. Results & Conclusions : Results obtained were as follows; 1. Polygoni Multiflori Radix did net reduce the focal cerebral infarct size induced by the middle cerebral artery occlusion under both hyperlipidemic and normal-lipid conditions. 2. Polygoni Multiflori Radix significantly reduced the increase of neuronal cell death in CAl region of hippocampus induced by the global cerebral ischemia under both hyperlipidemic and normal-lipid conditions. 3. Polygoni Multiflori Radix significantly reduced the increase of Bax expression in the CAl region of the hippocampus induced by global cerebral ischemia under both hyperlipidemic and normal-lipid conditions. 4. Polygoni Multiflori Radix significantly increased Bc1-2 expression in the CA1 region of the hippocampus after global cerebral ischemia under normal-lipid condition, but was not effective on that under hyperlipidemic condition. 5. Polygoni Multiflori Radix was not effective on serum total-cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride levels under normal-lipid conditions, irrespective of focal cerebral infarct or global cerebral ischemia. 6. Polygoni Multiflori Radix significantly reduced the increase of serum total-cholesterol and triglyceride levels, and increased serum LDL-cholesterol level under hyperlipidemic conditions, irrespective of foc31 cerebral infarct or global cerebral ischemia.

This study was conducted to investigate the effect of late-harvested green tea extract on serum and tissue lipid contents and Ca absorption. Sprague-Dawley male rats weighing 200g were fed high fit diets containing no tea(control), 0.5%(0.5LG), 1.0% late-harvested green tea extract(1.0LG), and 1.0% early-harvested green tea extract(1.0EG) for 4 weeks. Though daily food intake of experimental groups showed no significant difference from that of control group, daily body weight gain and food efficiency ratio were lower in all groups fed green tea extract. The contents of serum triglyceride of 1.0LG and 1.0EG groups and the content of serum total cholesterol of 1.0LG group were significantly lower than those of control group. The values of serum HDL-cholesterol in groups fed green tea extract were higher than that in the control group. LDL-cholesterol and atherogenic indices of all groups fed green tea extract were significantly lower than those of the control group. The contents of total lipid and triglyceride in liver were significantly lower in only 1.0LG group. For epididymal fit pad, the contents of total lipid and triglyceride in 1.0LG and 1.0EG groups were lower than those in the control group. The contents of total lipid excreted in feces were higher in groups fed diets of 1.0% green tea extract. There was no significant difference among experimental groups in Ca absorption. These results suggest that the administration of late-harvested green tea extract decreases the contents of fat in the body without reducing Ca absorption. (Korean J Nutrition 31(6) : 999-1005, 1998)
