Hypercholesterolemia has been regarded as a major risk factor of coronary heart disease(CHD). CHD is increasing in recent years among Koreans due to westernization of lifestyle and dietary behaviors. In the United States, implementation of the National Cholesterol Education Program(NCEP) had resulted 40% decline in mortality from CHD. This study was designed to evaluate the effect of medical nutrition therapy on serum lipid levels and discuss the effective nutrition education contents. Thirty outpatients(Male 40%, female 60%) with hypercholesterolemia were educated by medical nutrition therapy(MNT) protocol. At first visit and after three months of MNT, we assessed serum lipid profile, body weight and surveyed general characteristics, lifestyle and food habits through questionnaire. After 12 weeks of MNT, there were significant reductions in serum cholesterol and low-density lipoprotein cholesterol(LDL-C). Foods habits and lifestyle were changed to the desirable patterns. These results indicate that lipid profile is improved by changes of dietary behaviors and lifestyle. Especially in case of obesity, cholesterol lowering effect of MNT was more powerful. Consequently, MNT is effective on reduction of serum lipids by behavior change in hypercholesterolemic patients.

Active component was sought among three herb medicines, which are used in combination as a traditional medicine prescribed for patients with hyperlipidemia related diseases. Antihyperlipidemic effect of this remedy has previously been shown model by the authors on the animal model. Hyperlipidemia was induced on male Wistar rats by keeping them on high lipid diet for one week, as previously described by the authors. Blood lipid profile was verified on these rats by measuring total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). Then, the diet was changed to normal. At the same time, methanol extracts of Scutellaris baicalensis Georg.(radix), Coptidis japonica Makino(rhizoma) or Rhei koreanum Nakai(rhizoma) were given on daily basis, and changes in the blood lipid profile were monitored for 4 weeks. Methanol extract of Scutellaris baicalensis Georg. significantly reduced the TC value, implying the in vivo antihyperlipidemic effect.

This study was performed to examine the effect of excess vitamin A feeding on lipid profile and vitamin A content of rats. 12 male Sprague-Dawley rats. weighing 114.1$\pm$0.9g, were divided into control and excess vitamin A group, and fed experimental diet for 6 weeks. In the excess vitamin A group, the level of vitamin A was 400, 000 1.U./kg diet(100 times of standard level). It was observed that vitamin A excess group had higher levels of plasma total lipid, total cholesterol, and trighlyceride and lower HDL ratio, indicating a high risk to coronary heart disease. In the liver, total CHOL and TG content were also high, and fatty liver was produced by excess Vitamin A. Vitamin A contents of organs were higher when excess vitamin A was given. These results suggested that excess vitamin A could be a dietary factor increasing the lipid contents of plasma and liver. Therefore, it could be said that vitamin A megadose can be one of the risk factors to coronary heart disease.

Effects of extracts obtained from the flowers of Elsholtzia splendens on the serum lipid profile and hepatotoxicity in mice were investigated. Female ICR mice were given E. splendens ethanolic extract (ESEs) orally at a dose of 10 or 50 mg/kg BW for 50 days. Significant dose-dependent decreases in triglyceride and low-density lipoprotein (LDL)-cholesterol of serum were observed. In addition, ESEs prolonged the lag-time of LDL oxidation in vitro. In the serum of ICE mice given ESEs orally at 10 and 50 mg/kg BW, the serum levels of aspartate aminotransferase (AST) and lactic dehydrogenase (LDH) increased significantly, while total protein, albumin, creatinine, alanine aminotransferase (ALT), and total bilirubin did not change. Therefore, ESEs may be beneficial to human health, although it has some hepatotoxicity.

Two experiments in the sequential order were conducted to determine the effects of different dietary lipid sources on the growth and fatty acid composition of rohu (Labeo rohita) and to examine the viability of a return fish oil finisher diet in restoring the human cardio-protective fatty acid profile. In the first experiment, fish were fed either with coconut oil (D1), olive oil (D2), sunflower oil (D3), linseed oil (D4) and fish oil (D5) as the main lipid source in the isonitrogenous diet for 90 days. No significant differences in growth were observed. Among the experimental diets moisture content of fish varied significantly (p<0.05) between the groups. Dietary lipid sources had a profound influence on the fatty acid profile of the muscle and liver as tissue fatty acid profile reflected the dietary fatty acid composition. Increased amounts of eicosapentaenoic acid and docosahexaenoic acid were observed in tissue of fish fed D4 and arachidonic acid was observed in the tissue of fish fed D3. We have also detected the metabolites of n-3 and n-6 pathway in D4 and D3 groups respectively, which prompted us to conclude that rohu, can desaturate and elongate $C_{18}$ essential fatty acids to $C_{20}$ and $C_{22}$ HUFA. A second feeding trial was conducted using the animals from the five different treatment groups for the duration of 30 days with fish oil rich diet (D5). Feeding with fish-oil rich washout diet resulted in the near equalization of all the other treatment groups tissue fatty acid profiles to that of fish oil (D5) fed group. These results indicate that a finishing fish oil diet can be effectively used to restore the human cardioprotective fatty acid profile in rohu fed with vegetable oils as lipid source.

This work was undertaken to study the effect of dietary fat source on the fatty acid profile of pork, and to evaluate the effect of inclusion of vitamin E in pig diets on lipid oxidation of pork tissue and processed pork products. Fifty-six pigs were allocated to four treatments, that included two dietary fat sources and two levels of vitamin E inclusion. Dietary fat was derived from either tallow, a source of saturated fatty acids (SFA), or from a mixture of soybean and linseed oils, which contain polyunsaturated fatty acids (PUFA). Vitamin E was included at either 0% or 0.011% of the diet. Growth and carcass characteristics were not affected by the dietary treatments. Dietary fat source affected the fatty acid profile of the longissimus muscle and subcutaneous fat tissue, with the PUFA diet resulting in significantly more polyunsaturated fatty acids in the tissues, and more favourable ratios of SFA to PUFA and C18:2 to C18:3 in terms of human health considerations. Lipid oxidation was significantly greater in tissues and processed products from PUFA-fed pigs. Inclusion of vitamin E in the diets, however, reduced the extent of lipid oxidation in the meat and meat products. Dietary manipulation of the fatty acid profile of pigs is an effective means of altering the fat composition of pork in order to provide human consumers with a healthy product. Vitamin E is effective as an antioxidant agent, particularly where processed products are concerned.

We investigated the effects of antioxidant vitamins supplementation on antioxidative status and plasma lipid profile in female Korean non-insulin diabetes mellitus(NIDDM) patients. Forty-five patients were groups by types of vitamin to take into three groups-Vitam in E group(400IU/day, n=15), Vitamin C group (1,000mg/day, n=15) and Vitamin E plus C group (400 IU plus 1,000mg/day). Supplementation period was 4 weeks. After vitamins supplementation, plasma vitamin E concentration significantly increased in vitamin E and vitamin E + C group, but plasma retinol concentration were not affected by vitamin E or vitamin C supplementation. And plasma levels of lipid peroxide measured as thiobarbituric acid reactive substances(TBARS), indicator of lipid peroxidation and increased susceptibility of LDL towards lipid peroxidation, were significantly decreased in all three groups after vitamins supplementation. Also catalase activities in erythrocytes were significantly decreased after antioxidant vitamin supplementation in all subjects. And after vitamins supplementation, post prandial 2 hour glucose and total cholesterol levels was decreased in all subjects. And after vitamins supplementation, post prandial 2 hour glucose and total cholesterol levels was decreased in all patients, especially there was a significant difference in vitamin C, Vitamin E + C group. In this study, antioxidant vitamins supplementation might have a protective function against the free radical-mediated lipid peroxidation and decrease the plasma total cholesterol levels in Korean female NIDDM patients.

This study was performed to investigate nutritional intake, the dietary behaviors and plasma lipid profile between smokers and non-smokers of college male students in the Gyeonggi Area. Dietary behaviors and attitude toward smoking were investigated by questionnaires. The result obtained were as follows: There was no significant difference in anthropometric measurements between smokers and nonsmokers. There was no significant difference in dietary behaviors. However, smokers tended to eat more snacks and desserts than nonsmokers. In plasma lipid levels, smokers had higher levels of plasma triglyceride, LDL-cholesterol, VLDL-cholesterol and total cholesterol than that of non-smokers(p<0.05). HDL-cholesterol level of smokers was a lower than that of non-smokers although the difference was not significant. AI(Atherogenic Index), Total /HDL cholesterol ratio and LDL/HDL cholesterol ratio of smokers were significantly higher than that of non-smokers(p<0.01). BMI and SBP showed positive correlation with triglyceride(p<0.01) and VLDL-cholesterol(p<0.01). DBP showed positive correlation with triglyceride(p<0.001) and VLDL-cholesterol(p<0.01).

The purpose of this research was to investigate the effect of the calcium intake on lipid profile and antioxidant capacities in ovariectomized (OVX) rats. Rats were divided into 3 groups and fed diet with different levels of calcium (low 0.1%, adequate 0.5%, high 1.5%) for 4 weeks. The half of rats in each group was ovariectomized and the others were sham-operated. And rats were fed same diets for 8 weeks after operation. Feed intake and weight gain were significantly higher in OVX group than those in sham-operated. Serum HDL-cholesterol was the highest in high-calcium group of OVX. Hepatic triglyceride of low-calcium group in sham-operated was the highest, while that of highcalcium group in OVX was the highest. Hepatic activities of glutathione-S-transferase (GST), glutathione peroxidase (GSH-Px), and catalase were significantly decreased by increasement of calcium intake. Hepatic TBARS level was the lowest in high-calcium group of OVX. And hepatic level of TBARS induced by AAPH was significantly decreased by increasement of calcium intake. These results may indicate that the high calcium intake have the potential role to improve lipid profiles and antioxidant capacities in OVX rats.
