The purpose of this study was to examine the impact of isoflavones on lipid concentrations and hepatic LDL receptor mRNA level in growing female rats. Twenty four rats (body weight $75\pm5g$) were randomly assigned to one of two groups, consuming control diet or isoflavones supplemented diet (57mg isoflavones/100g diet). All rats has been fed on experimental diet and deionized water ad libitum for 9 weeks. The concentration of triglyceride and total cholesterol were measured in serum and liver. Serum HDL cholesterol was measured. Hepatic LDL receptor mRNA level was tested by RT-PCR. Supplementation of isoflavones did not affect weight gain, mean food intake and food efficiency ratio. Serum total cholesterol and non-HDL cholesterol of isoflavones supplemented rats were significantly lower than those of control rats (p<0.05). But hepatic cholseterol was not influenced by supplementation of isoflavones. Hepatic LDL receptor mRNA level not significantly different between control group and isoflavones supplemented group. Therefore, isoflavones may be beneficial on serum cholesterol and non-HDL cholesterol lowering in growing female rats.

This study was performed to investigate the effect of chongkukjang intake on lipid metabolism and liver function in ethanol consumed rats. Twenty one Sprague-Dawley male rats aging 4 weeks old were used as experimental animals, which were divided into three dietary groups; casein diet(CA), soybean diet(SB) and chongkukjang diet(CJ). Alcohol was consumed with water as 25%(v/v) ethanol solution. After 4 weeks of experimental period, rats were sacrificed to get blood and liver samples for analysis of lipids, lipid peroxides, antioxidative enzymes and biochemical indices of liver function. The mean body weight, food intake and liver index were not significantly different among three groups. Serum level of total lipid, triglyceride and total cholesterol of chongkukjang diet group was the lowest among three groups although the difference was not significant. HDL-cholesterol level was significantly(p<0.05) higher in chongkukjang diet group than that of casein diet group. LDL-cholesterol level of chongkukjang and soybean diet group was significantly(p<0.05) lower than that of casein diet group respectively. Liver TBARS of chongkukjang and soybean diet group was significantly(p<0.05) lower than that of casein diet group respectively. The superoxide dismutase activity of chongkukjang diet group was significantly(p<0.05) higher than that of casein diet group. Catalase activity was not significantly different among three groups. As indices of liver function, glutamic oxaloacetic transminase(GOT), glutamic pyruvic transminase(GPT), $\gamma$-glutamyl transpeptidase($\gamma$-GTP) and lactate dehydrogenase(LDH) were not significantly different among three groups. Serum alcohol concentration and activities of alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) were not significantly different among three groups. The chongkukjang diet seems to give a beneficial effect for improving lipid metabolism by increasing HDL-cholesterol level and SOD activity while reducing liver TBARS level. However, effect on liver function has to be investigated further.

Hyperlipidemia has been treated as one of the most important etiological cause factor in 21th century. The cortex and root of Acanthopanax sessiliflorus (AR), a herbal medicine, have been used for several diseases including cardiovascular diseases in Oriental countries. Recently, we reported that AR has anti-hyperlipidemic action. BS-01 was made using extract from AR. For these reasons, we investigated the effects of BS-01 as anti-hyperlipidemic drug through measurement of body weights, cholesterol levels, total lipid, phospholipid in serum. In our results, mice induced by high fat diet elevated body weight level compared to naive group. And total lipid in serum was also elevated by induction of hyperlipidemia. In BS-01 group, body weight of mice was lowered significantly compared to that of control group. Oral administration of BS-01 decreased total cholesterol and triglyceride level back to that of naive mice. HDL and LDL cholesterol levels were not affected by BS-01. In addition, total lipid level, which elevated by induction of hyperlipidemia was also lowered by oral administration of BS-01. Finally, free fatty acid level was lowered in BS-01 group. These results demonstrate that BS-01 lowered body weight and titers involved in hyperlipdemia such as total cholesterol, triglyceride, free fatty acid and total lipid. In these results, we demonstrate that BS-01 has anti-hyperlipidemic action.

This study explored the effects of dietary calcium level and Hijikia fusiforme supplementation on bone indices and serum lipid levels using 36 female Sprague-Dawley rats as a model. Rats received low Ca diet for 3 weeks after ovariectomy. The rats were then divided into six dietary groups and fed low (0.1% Ca), normal (0.5% Ca) and high (1.5% Ca) Ca diets (CaL, CaN, CaH) and low, normal, high Ca diets with Hijikia fusiforme supplementation (CaLH, CaNH, CaHH) for 3 weeks. After each experimental periods, 24 hour urine and/or blood samples, left and right femurs were collected for analysis. Serum Ca concentration showed no significant difference by dietary Ca levels and Hijikia fusiforme supplementation. Alkaline phosphatase activity was significantly higher in normal and high Ca group compared to low Ca group. Serum total cholesterol, triglyceride and total lipid were not significantly different among groups. HDL-cholesterol showed no significant difference by Hijikia fusiforme supplementation. However, the normal and high Ca groups showed significantly higher HDL-cholesterol compared to the low Ca group. Urinary hydroxyproline and hydroxyproline/creatinine ratio were not significantly different among groups. The wet weight of the femur was significantly higher in low Ca group compared to normal or high Ca group. The dry weight, wet weight/body weight, length and breaking force of the femur were not significantly different among groups. Ash contents/wet weight of the femur was significantly increased as dietary Ca levels up and significantly higher in Hijikia fusiforme supplementation groups. The Ca content of the femur were significantly higher in the normal and high Ca groups than the low Ca group. However, there was no significant difference in Ca content by Hijikia fusiforme supplementation.

This study was performed to investigate the effect of chitosan and NOCC from different sources and of different molecular weights on lipid metabolism. Sprague-Dawley rats were blocked into 26 groups according to body weight, and were raised for 4 weeks. Cadmium chloride was given at the level of 0 or 400 ppm in diet. Various chitosan and NOCC sources were given at the level of 0%(w/w) of diet. Total serum cholesterol and serum triglyceride concentrations were little affected by chitosan and NOCC supplements. However, HDL-cholesterol concentration and HDL : total cholesterol ratio were increased , and liver lipid, cholesterol , and triglyceride concentration were decreased by chitosan and NOCC supplements. The cholesterol and lipid lowering activity depends on fiber sources(crab and shrimp); type (chitosan and NOCC); and molecular weight(low , medium , and high). Among cadmium-free groups, chitosan-fed groups showed greater activity than NOCC -fed groups in lowering cholesterol and lipid levels, and greater fecal excretion of lipids and bile acids. Crab chitosans were more effective in cholesterol and lipid lowering activity than shrimp chitosans. The group fed high molecular weight crab chitosan showed the highest fecal excretion of lipids and bile acids. This indicated that high molecular weight crab chitosan was most effective in interfering with cholesterol and lipid absorption.

Objectives: This study compared serum lipid concentration according to drinking habits. Methods: We analyzed data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII). The study included 8,525 adults (3,651 males and 4,874 females), aged 30 - 59 years. Results: There were differences in age, gender, education level, smoking status, physical activity, and waist circumference between drinkers and abstainers. The serum low-density lipoprotein-cholesterol (LDL-C) level of the drinkers was lower than those of the abstainers (P < 0.05). The serum triglyceride (TG) and high-density lipoprotein-cholesterol (HDL-C) concentrations were highest in the group that consumed alcohol 'more than twice a week' relative to the other groups (P < 0.001). The LDL-C and atherogenic index (AI) levels were lowest in the 'more than twice a week' drinking group compared to the other groups (P < 0.001). The serum TG and HDL-C concentrations were the highest in the '7 glasses/time' group (P < 0.001). The serum LDL-C concentration was the lowest in the '7 glasses/time' group (P < 0.001). Notably, the higher the frequency of binge drinking (7 glasses or more), the higher the concentration of TG (P < 0.001). The serum HDL-C concentration was significantly higher in the 'no binge' and 'more than once a week' groups compared to the other groups (P < 0.001). The serum LDL-C concentration and AI score were the lowest in the 'more than once a week' group (P < 0.001). Conclusions: As the quantity and frequency of drinking increased, the serum TC concentration increased. Moreover, an increase in the serum HDL-C concentration led to a decrease in AI. The factors exacerbating cardiovascular disease increased simultaneously due to drinking. Our results suggest that for individuals with hypertriglyceridemia and patients with low HDL-cholesterolemia, separate guidelines based on the quantity and frequency of alcohol consumption are warranted.

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.

This study was conducted to investigate the effects of caffeine on lipid and mineral content in the serum of rats given a caffeine free diet(FC), a low caffeine diet(LC), a medium caffeine diet(MC), a high caffeine diet(HC) or a super-high caffeine diet(SHC) for 5 weeks. Thirty male Sprague-Dawley rats(body weight, $110{\pm}0.3$ g) were blocked into 5 groups and fed diets with or without pure caffeine. Caffeine intake models showed a lower mean-weight gain, food intake and food efficiency in the high caffeine diet groups(MC, HC and SHC groups) than the groups receiving a caffeine free or low caffeine diet(FC and LC groups). Serum total lipid, total cholesterol and LDL-cholesterol levels decreased, but the serum HDL-cholesterol level increased according to the increase in caffeine intake. Serum total lipid, HDL-cholesterol and serum triglyceride were significantly lower in the HC and SHC groups than the FC group. All of the serum minerals decreased as caffeine intake increased. Serum iron, calcium, magnesium and phosphorus significantly decreased in the HC and SHC groups compared to the FC group. Caffeine intake was associated with less weight gain and reduced serum total cholesterol, triglyceride and total lipid. The results suggest that rats fed high amounts of caffeine may be susceptible to osteoporosis due to their low levels of calcium, magnesium and phosphorus.
