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.

Trans fatty acids (TFAs), especially elaidic acid, formed during partial hydrogenation of vegetable oils have been shown to increase LDL-cholesterol (LDL-C) and decrease HDL-cholesterol (HDL-C), thereby increasing the LDL-C/HDL-C ratio and elevating the risk of cardiovascular disease. However, studies on the health effects of ruminant TFAs have suggested that these TFAs, which are primarily vaccenic acids, have no or inverse association with coronary heart disease. Thus, dietary recommendations or legislation for TFAs should consider the differences in the physiological effects of TFAs derived from various food sources. This present review recapitulates the progress in TFA research by analyzing recent epidemiological studies or intervention studies and comparing the cardiovascular health effects of industrially produced TFA and ruminant TFA.

This study showed the effect of fermented milk on the cholesterol level of Korean. 130 persons among the teachers of elementary, middle and high schools, professors and graduate school students were divided into two groups according to their cholesterol level and provided with fermented milk 300 $m\ell$ dairly from Sep.25 to No. V3. They were given blood test at 20 days and 40 days after drinking fermented milk, and surveyed about their ordinary life style and the change of fecal condition. Cholesterol, LDL and the ratio of LDL and HDL in blood were significantly decreased in both high cholesterol group and normal group while HDL cholesterol was notably increased. TG showed slightly tendency of decrease in normal group while no changed in high group. There is no significant change in cholesterol level after drinking fermented milk among groups which are divided by factors of dringking, smoking, caffeine, B.M.I. and family history. The research also showed that drinking fermented milk improved the fecal frequency and fecal condition.

The principal objective of this study was to assess the effects of chitosan oligosaccharide supplementation on the improvement of blood glucose, lipid components and enzyme activities in the serum of streptozotocin(STZ, 55 mg/kg B.W., I.P. injection)-induced hyperglycemic rats fed on experimental diets for 5 weeks. The concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglycerides(TG) and phospholipids(PL) in serum were remarkably higher in the hyperglycemic group(group BSW) and STZ(I.P.)+chitosan oligosaccharide supplementation group(group ECW) than those in the control group(group BW, basal diet+water). However the concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, tree cholesterol, cholesteryl ester ratio, TG and PL in serum were lower in the ECW group than in the BSW group, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the ECW group were higher than in the BSW group. The activities of alkaline phosphatase(ALP) and aminotransferase(AST, ALT) in serum were lower in the ECW group than in the hyperglycemic BSW group. The results shown above suggested that chitosan oligosaccharide supplementation effectively improves blood glucose, lipid composition and enzyme activities in the sera of STZ-induced hyperglycemic rats.

This study was done to investigate the association of blood clinical parameters and dietary intakes with serum adiponectin level. Athropometric measurement, dietary intakes, serum lipids and adiponectin levels were examined in 160 overweight and obese women. The subjects were divided into 5 groups by quintile according to serum adiponectin level. Weight, BMI, waist circumferences and waist/hip ratio of the highest quintile group were significantly lower than those of the lowest quintile group. Serum lipid analysis showed a significant higher level of TG, LDL-cholesterol, LDL/HDL ratio, AI, and serum hs-CRP in the lowest quintile group. Similarly, correlation data also showed that serum adiponectin level was positively correlated with serum HDL-cholesterol level (p < 0.01) and was negatively correlated with BMI (p < 0.01), waist circumferences (p < 0.01), waist/hip ratio (p<0.01), systolic (p < 0.01) and diastolic blood pressure (p < 0.05), TG (p < 0.01), LDL-cholesterol (p < 0.05), LDL/HDL ratio (p < 0.05), AI (p < 0.01), Homa-IR (p < 0.01), hs-CRP (p < 0.05) and leptin (p < 0.05). Dietary intake data showed that protein intake was significantly lower in the highest quintile group compared to the lower quintile groups while intakes of vitamin C was significantly higher in highest quintile group after adjustment by BMI, waist and energy intake, In addition, the highest quintile group had higher fiber intakes than the lower quintile groups. These results might suggest that a diet high in fiber and vitamin C and low in protein for obese patients would better be recommended to improve adiponectin level. However, further research is needed to elucidate the association of dietary intakes or dietary patterns and serum adiponectin level.

The purpose of the study was to find an effect of medium chain triglyceride (MCT)diet on the serum lipids and lipoprotein of Sprague-Dawley rats when the were fed with cholesterol. All experiment-groups were fed with different diet such as soybean oil, shortening,MCT and MCT mixed with oil respectively. After fed to each group, the levels of serum lipids and lipoprotein among fed rats were examined and the data from the experiment were compared with a control group. The results obtained from the study are as follows : (1) The average boby weight gain in MCT diet and soybean oil diet groups were lighter than that of the control group, while the food efficiency ratio in each experimental diet group was almost same as than in the control group. (2) Total cholesterol levels in serum of all experimental diet groups were lower than that of the control group except the level in shortening diet group. Especially, the levels of total cholesterol in MCT diet and soybean oil diet groups were significantly lower than that of the control group. (3) VLDL, LDL-cholesterol levels of all experimental groups were almost same except the case of the MCT diet and soybean oil diet group which was significantly low. (4) The ratio of VLDL, LDL-cholesterol to HDL-cholesterol, so called, atherogenic index in serum of MCT and soybean oil diet groups were significantly lower than that of the control group. (5) The ratio of total cholesterol to phospholipids in serum of MCT diet group was decreased, because total cholesterol levels were decreased more than phospolipid levels. (6) The ratio of the serum VLDL, LDL to HDL in MCT diet group. in MCT and soybean oil mixed diet group, and in soybean diet group was decreased. In other wards, it means that the decrease of the serum VLDL, LDL in each group and the increase of the serum HDL.
