  • The purpose of this study was to determine whether vitamin {TEX}$B_{6}${/TEX} deficiency and age affect the blood cho-lesterol profile in exercising rats. Fifty four rats were fed either a viramin {TEX}$B_{6}${/TEX} deficient dief(-{TEX}$B_{6}${/TEX}) of a control diet(+{TEX}$B_{6}${/TEX}) for 6 weeks, then subdivided into 3 groups:non-exercise group(NE), exercise and sacrifice group(ES), exercise and recuperation group(ER). ES group was exercised in treadmill({TEX}$10^{o}${/TEX}, 0.5~0.8km/h) for 2 hours and sacrifice. ER group was recuperated three days with respective diet after exercise. At week 3 and 6, and level of plasma total cholesterol(TC), high density lipoprotein cholesterol(HDL_C) and low density lipoprotein cholesterol(LDL_C) were compared. In NE group, there was no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats. The plasma levels of TC and LDL_C of 6 weeks were higher than those of 3 weeks and on difference in HDL_V between 3 weeks rats and 6 weeks rats. In ES group, there was also no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats and there was no difference in TC, LDL-cholesterol between 3 weeks rats and 6 weeks rats. The level of HDL_C pf 6 weeks was lower than that of 3 weeks rats. In ER group, there was no difference in the levels of TC and LDL_C not only between +{TEX}$B_{6}${/TEX} rats and-{TEX}$B_{6}${/TEX} rats but also between 3 weeks rats and 6 weeks rats. The level of HDL_C was lower in -{TEX}$B_{6}${/TEX} rats than in +{TEX}$B_{6}${/TEX} rats and higher in 6 weeks rats than in 3 weeks rats. These results suggest that vitamin {TEX}$B_{6}${/TEX} deficiency may affect the HDL_C during exercise and after recuperation. The desirable effect of exercise on plasma Cholesterol profile is strengthened in adult age than young age.

  • In the present study, we investigated the effects of chronic green tea consumption on the serum lipid profiles of 92 subjects (mean age: 59.5 $\pm$ 8.9, men: 41, women:51) living in a green tea cultivation village. The anthropometric and biochemical blood indices were measured, and nutritional intakes were assessed using 24-h recall method. Also, we administered a questionnaire regarding green tea consumption. The subjects were divided into three groups based on the period of green tea consumption (0, < 10 year, and $\geq$ 10 year). There were no significant differences in age, anthropometric indices (Wt, Ht, BMI, Body fat, LBM), and nutritional intakes among the groups. Serum LDL-cholesterol concentration was significantly lower in the $\geq$ 10 year group compared with the other groups (p < 0.05). Also, the LDL/HDL-cholesterol ratio was significantly lower in the $\geq$ 10 year group compared with the other groups (p < 0.05). The frequency of subjects with a normal range of serum LDL-cholesterol concentration (< 200 mg/dl) was significantly higher in the $\geq$ 10 year group compared with the other groups (p < 0.05). These results imply positive effects of chronic green tea consumption on blood lipid profiles, which requires confirmation in further studies.

  • This study was designed to investigate the hyperlipidemia-healing effect of liquid extract from Mageum-tang(麻芩湯), it was performed on the hyperlipidemia of rats induced by high cholesterol diet and Triton WR-1339. We prepared two types of hyperlipidemia model in rats induced by high cholesterol diet and Triton WR-1339. The amount of total cholesterol, HDL-cholesterol, LDL -cholesterol, triglyceride, phospholipid, free fatty acid, the activity of superoxide dismutase(SOD), and glutathione were measured. The liquid extract from Mageum-tang showed significant decreasing effects on total cholesterol, LDL- cholesterol, triglyceride, phospholipid, free fatty acid in the both model. And it showed significant increasing effects on HDL-cholesterol, the activity of SOD in both model and amount of glutathione in Triton WR-1339 model. These results suggest that liquid extract from Mageum-tang has healing efficacy on hyperlipidemia induced by high cholesterol diet and Triton WR-1339.

  • Lipid peroxidation (LPO) has been identified as an important component of atherosclerosis. In this study, the effects of supplementation with cholesterol (0.5%), olive oil (5%) and vitamin E (0.05%) on erythrocyte glutathione (GSH), plasma malondialdehyde (MDA), total cholesterol, HDL-LDL cholesterol and triacylglycerol, brain and liver MDA and GSH concentrations of rats were investigated. A total of 50 Sprague-Dawley male rats aged 6 months, and of equal body weight were used and fed a standard ration ad libitum. Animals were housed in the University of Selcuk, Veterinary Faculty Experimental Animals Unit. The experiment lasted 60 days and there were five experimental groups as follows: 1. Control, 2. Cholesterol (0.5%), 3. Olive oil (5%), 4. Cholesterol plus vitamin E (0.05%), 5. Olive oil plus vitamin E (0.05%). At the end of the experiment, blood samples were taken by cardiac puncture and erythrocyte GSH, plasma MDA, cholesterol, HDL-LDL cholesterol, triacylglycerol and also GSH and MDA concentrations in brain and liver tissue of rats were spectrophotometrically determined. Supplementation of olive oil and cholesterol into rat diets (groups 2 and 3) caused significant differences in lipid parameters; HDL cholesterol concentrations were increased in the olive oil group and LDL cholesterol was lower than in the cholesterol fed group. Moreover, these decreases in LDL and triacylglycerol concentrations were more significant with vitamin E supplementation. The high plasma MDA concentrations showed that lipid peroxidation occurred in the olive oil group and the highest brain MDA concentrations were determined also in the olive oil group. These findings suggest that vitamin E addition may decrease the sensitivities of several oils to oxidation and that monounsaturated fatty acids in olive oil may decrease the incidence of atherosclerosis by regulating blood lipid profiles.

  • The objective of this literature review is to prove that egg cholesterol is not related with heart disease based upon research results of the past 50 years. As a result, it was reported that the dietary intake cholesterol did not affected cholesterol levels in blood. Moreover, it was reported that adding two eggs a day to a healthful diet did not significantly increase blood cholesterol levels in young or middle-aged men and women with normal or even moderately elevated blood cholesterol levels. Cholesterol feeding studies demonstrate that dietary cholesterol increases both LDL and HDL cholesterol with little change in the LDL : HDL ratio as an important risk indicator of heart disease. Especially a good indicator in the elderly from increased HDL-cholesterol, so cholesterol intake appeared to be good for the prevention of heart disease. Thus the consumption of eggs is bad for your health is not known as a fact, but rather was found to be effective in preventing heart disease. Also, all consumers may consume without worrying because there are no official standards regarding egg intake. Therefore, these evidences would clear up some misunderstanding and mistrust on egg cholesterol regarding the consumption of egg as well as give some desirable advice on how to maintain healthy life.

  • We investigated the effects of unripe black raspberry water extract (UBR-W) and oxidation-LDL treatment on cholesterol levels. Experiments using an established human hepatocellular carcinoma cell line (HepG2) showed a time-dependent increase in expression of LDL receptor after UBR-W treatment. Expression of LDL receptor-related genes, such as SREBP1 and 2, increased upon UBR-W treatment. However, expression of HDL-related genes was unaffected by UBR-W. HMG-CoA reductase activity was reduced by UBR-W treatment, whereas HMG-CoA mRNA expression significantly increased. In addition, the ApoB/ApoA1 mRNA level, which is a predictor of cardiovascular risk, was reduced in a time-dependent manner by UBR-W treatment. Macrophage-like cells (RAW 264.7) showed increased expression of ox-LDL-related genes, such as CD36, scavenger receptor-A, adipophilin, and PPAR-gamma, upon ox-LDL treatment compared to untreated control cells, and quantitative lipid analysis indicated a dramatic increase in lipid accumulation. However, UBR-W treatment significantly reduced expression of ox-LDL-related genes and largely prevented lipid accumulation. The results indicate that UBR-W mediates a cholesterol-lowering effect via inhibition of cholesterol synthesis and induction of LDL uptake through SREBP.

  • Objectives : The protective effect of Vasopurus, a mixture of three medicinal plants, on atherosclerosis induced by dietary cholesterol in low density lipid (LDL) receptor deficient mice was studied. Methods : Experimental groups were divided into three groups of six animals each; a normal group (N); a high cholesterol group (HC), a high cholesterol plus Vasopurus group (HCVA). The experimental groups were fed for 6 months. Results : Vasopurus supplementation significantly lowered plasma total cholesterol and LDL cholesterol conc entrations compared with the high.cholesterol (HC) diet group. In addition, supplementation with Vasopurus significantly increased fecal cholesterol contents compared to mice fed a HC diet. Mice whose diet was supplemented by Vasopurus showed considerably fewer atherosclerotic plagues in the aortic values of heart and aortas compared to mice receiving the HC diet. Conclusions : These results indicate that Vasopurus has efficacy in anti.atherosclerosis medication.
