To examine the effects of pomegranate on cerebral blood flow and obesity, we observed regional cerebral blood flow in normal rats, as well as body weight, serum total cholesterol, serum HDL-cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels in rats fed a high fat diet. The results were as follows. Pomegranate seed extract significantly increased regional cerebral blood flow and the peel extract increased regional the cerebral blood flow in a dose dependent manner. In addition, the pomegranate extracts(seed, peel, juice) decreased body weight, serum total cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels, and increased serum HDL-cholesterol in the rats fed a high fat diet. More specially the seed extract significantly decreased serum total cholesterol, serum triglycerides and serum phospholipid levels.

This experimental study was designed to investigate the inhibitory effects of Sojihwangamibang on hyperlipidemia in rats induced by high cholesterol diet diet. Sprague- Dawley rats were divided into normal group, control group, SJB treated group. Obese rats were induced by high cholesterol diet treatment for 6 weeks including a oral administration of SJB for 4 weeks. In SJB group, serum total cholesterol, LDL cholesterol, triglyceride and glucose were significantly decreased, and HDL cholesterol was significantly increased compared with untreated control group. In SJB group, HMG-CoA and ACAT concentration of hepatic homogenate were significantly decreased compared with untreated control group. These results provide experimental evidence that SJB, applied currently in the clinical practice, appears to be effective for down-regulating risk factors of hyperlipidemia, and thus may be used as an objective information for the development of therapeutic agents.

Postmenopausal women are at an increased risk of developing coronary artery disease. This is due to primarily dyslipidemia accompanying the loss of estrogen secretion. Soy isoflavones are known to have weak estrogenic effects. The purpose of this study is to investigate whether isoflavone supplement improves the risk of cardiovascular disease in hypercholesterolemic postmenopausal women. Subjects consisted of 39 Korean postmenopausal women with hypercholesterolemia (total cholesterol $\geq$ 200 mg/㎗ or LDL cholesterol $\geq$ 130 mg/㎗). Subjects were divided into 2 groups; placebo group (PG), isoflavone supplement group (IG). During 12 weeks, subjects were given placebo and 80mg isoflavone daily. Anthropometric measurement, blood sample analysis and dietary intake measurement were taken at baseline and after 12 weeks. After 12 weeks, systolic blood pressure was decreased significantly (p ＜ 0.01) and plasma HDL cholesterol level was increased significantly (p ＜ 0.05) in IG. But there were no significant changes in plasma total cholesterol, LDL cholesterol and triglyceride levels after isoflavone supplementation. There was a negative correlation between initial plasma HDL cholesterol level and the extent of plasma HDL cholesterol reduction in IG (r＝-0.572, p＝0.012). Atherogenic index (AI), total-/LDL- cholesterol ratio and LDL/HDL cholesterol ratio were improved significantly after isoflavone supplementation. In subjects whose initial plasma LDL cholesterol level were above 160 mg/㎗, plasma malondialdehyde (MDA) level were decreased and total antioxidant status (TAS) were increased significantly after isoflavone supplement (p ＜ 0.05). However there were no significant changes in flow-mediated dilator (FMD), the marker of endothelium-dependent vasodilation and nitroglycerine-mediated dilator (NMD), the marker of endothelium-independent vasodilation and the extent of DNA damage after isoflavone supplement. In conclusion, these results indicate that isoflavone supplement may decrease the risk of cardiovascular disease via improving blood pressure, HDL cholesterol level and AI in hypercholesterolemic postmenopausal women. Futhermore, in case of subjects with elevated LDL cholesterol level, isoflavone supplementation may have more antiatherogenic effects via improving antioxidant status.

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 effect of milk in low and high cholesterol diets were investigated on serum cholesterol esterification. Weanling male Sprague-Dawley rats were divided into low(0.01% w/w) and high (1.01% w/w) cholesterol-diets groups. Bothlow and high cholesterol groups were consisted of three groups : control , LM(low heat milk), and HM (high heat milk) groups. After feeding these experimental diets for six weeks, serum cholesterol (free cholesterol and cholestryl ester) concentration and activity of lecithin.: cholesterol acyltransferase (LCAT) were measured, and serum lipoprotein profile was examined using gel column chromatography. According to the result, activity of LCAT was elevated independently by intakes of high cholesterol and milk , which resulted in the increase of daily turnover of serum cholesteryl ester. However, the turnover of HDL-cholesteryl ester increased only by milk. LCAT activity was moderately correlated with levels of total-and HDL-free choelsterol. It is concluded from the present study that milk had the cholesterol-lowering effect which partly appears to be mediated through facilitated reverse cholesterol transport.

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.

The purpose of this study was examine the relationship between smoking, general characteristics, and serum lipids in the normal adult. The subjects consist of 6,800 persons (male ; 4,309(63.4%), female ; 2,491(36.6%)) in A hospital in Kyungki-Do. The collected data were analyzed using T-test, and Multiple Regression by SPSS/WIN program. The result were following ; 1. Cigarette smoking was associated with decreased serum HDL cholesterol level (p<.001). 2. Serum LDL cholesterol level was not statistically correlated with smoking tend to level by 5.77mg/dl respectively. 3. Cigarette smoking was associated with elevated serum Triglyceride level (p<.001). 4. By using regression, HDL cholesterol level was negatively correlated with obesity and alcohol.. HDL cholesterol level was positively correlated with exercise. LDL cholesterol level was positively correlated with diet and obesity.　Triglyceride level was positively correlated with obesity and　alcohol. In conclusion, Smoking was the most correlated with Triglyceride among the serum lipid and Serum lipid was the most correlated with obesity. Thus, it is necessary to quit smoke and weight control for prevention from disease such as coronary heart disease and lung cancer.
