This study was designed to investigate the antihyperlipidemic activity of Fermented Rhus Verniciflua Stokes Extract(FRVSE) on diet-induced hyperlipidemia in rats. The animals were divided into 4 groups of the normal group(fed with normal diet), control group(fed with high fat diet), sample A group(fed with high fat diet and medicated FRVSE 192 ㎎/㎏/day), sample B group(fed with high fat diet and medicated FRVSE 384 ㎎/㎏/day), and received oral administration of each prescription with diet for a period of six weeks. The changes in the body weight, the liver weight, the epididymal fat weight, and the plasma levels of total cholesterol, triglyceride(TG), high density lipoprotein(HDL) cholesterol and low density lipoprotein(LDL) cholesterol were measured. In sample A group, the weight of liver and plasma level of TG decreased significantly. There was a significant decrease in the plasma level of total cholesterol, TG and LDL cholesterol in the sample B group. These results suggest that the FRVSE have a good antihyperlipidemic activity and a potential to treat hyperlipidemia.

The purpose of this study was to investigate effects of swimming training and cholesterol diet on the activation of hepatic antioxidant enzymes and serum lipid in Sprague Dawley rats(24 weeks of age). They were divided into five groups which were made up of normal-diet detraining group(C), 2% cholesterol-diet detraining group(CC), 2% cholesterol-diet swimming training groups which were classified according to their training time(CSA: 12min, CSB:8min, CSC:4min). They were given normal diet for the first 6weeks and then, separated normal-dietary and 2% cholesterol-dietary for 14 weeks. During these periods, 10 weeks’ swimming training was performed after 4 weeks later. And then we analyzed blood and liver by decapitating those rats. Swimming training showed a tendency to increase the activation of GSH-peroxidase, Nonprotein-SH and malondialdehyde, and decrease total- cholesterol, LSL-C/HDL-C and VLDL significantly. Whereas, cholesterol diet which has no training showed decrease the activation of hepatic antioxodant enzymes, and increase total-cholesterol and LDL-C/HDL-C absolutely. These results suggest that swimming training should stimulate the activation of hepatic antioxidant enzymes and decrease total-cholestrol even if they had cholesterol diet.

The purpose of this experiment was to study the effect of feeding winged bean (Psophocarpus tetragonolobus) oil on egg cholesterol and fatty acid of Japanese quail. Four groups of 10-week-old Japanese quails (n=10 per group) were fed a basal diet (20% CP, 2890 kcal/kg) supplemented with 5% of either animal tallow, soybean oil, corn oil or winged bean oil over an 8-week period. At the end of the experiment, 7 birds in each treatment were killed by decapitation. Blood samples and livers were collected for cholesterol analyses. There were no significant differences in final body weight, feed intake, egg production, egg and yolk weight due to the different oil treatments. Egg and plasma cholesterol levels obtained with the winged bean oil diet were higher than those obtained with the animal tallow or soybean oil diets, but were not significantly different from those obtained with com oil diet. Egg lipid, liver lipid and liver cholesterol content was lower with the winged bean oil diet than with the animal tallow diet. It may be concluded that the winged bean oil diet did not impair laying performance, but increased egg and plasma cholesterol levels compared with soybean oil or animal tallow diets. Winged bean oil diet produced eggs with a higher oleic content and lower linoleic content compared with the soybean or com oil diet.

This study was designed to observe the effects of both control and atherogenic diets on the cholesterol and triglyceride (TG) in serum and liver of adult rats fed diets supplying two levels of dietary fat and two different sources of dietary protein in early life. For the first experimental period, the rats were assigned into the four diet groups: High fat, casein (HC); High fat, gluten (HG); Low fat, casein (LC): Low fat, gluten (LG). Each group was subdivided into control and atherogenic groups for the second experimental period. Cholesterol and TG were determined in serum and liver after 7 hr fasting. The body weight gain was greater in the rats of the casein groups than those of the gluten groups tut not influenced by the level of the dietary fat. The difference in body weight from the quality of dietary protein in the first period was not disappeared even after the second period. After the first period, higher serum cholesterol was observed in the rats fed either casein or high fat diets. With the second experimental diet, rats fed atherogenic diet showed higher serum cholesterol concentration but lower serum TG levels compared to those fed control diet, regardless the diets fed in the first period. Serum cholesterol level of the rats of both groups which had been fed high fat diets in early life was increased compared to those of the low fat diet groups. This effect was more pronounced with the atherogenic diet groups than control groups. However, no differences were found in serum cholesterol levels resulted from the different types of dietary protein fed in the first period. Serum TG concentration was not influenced by the quality of protein and level of fat in the diet but seemed to be mere affected by the amount of carbohyrates in the diet. Liver cholesterol per unit weight was greater in the gluten diet groups than in the casein groups but total cholesterol was higher in casein fed rats. There were no differences in liver TG among the groups.

The feeding effects of Herba hottuynia extracts on the lipids profiles and the content of TAB-reactive substances were evaluated in rats fed a high cholesterol diet. Hot water or ethanol extracts of the dried leave were evaporated and lyophilized . The experimental animals wer edevided to four groups and fed the following diets for 4 weeks : BAsal (cholesterol-free diet), CHOL(cholesterol-enriched diet),CW (cholesterol plus water extract) and CE(cholesterol plus ethanol extract). Dietary cholesterol increased significantly the activities of serum GOT and GPT, but the extracts feeding (0.5% of diet) did not influence the activities induced by dietary cholesterol. Although dietary cholesterol increased significantly the concentrationof serum andliver cholesterol, it tended to decrease the concentation of serum triglycerides. CHolesterol feeding had a lowering effect on the lipid peroxidation value of serum, but not inliver.Furthermore, the extracts feeding, especially water extract, decreased markedly the liver peroxidation value. The results suggest that Houttyunia cordata extracts have an in vivo antioxidant effect, judged from the TBA value in the liver rats fed a high cholesterol diet.

This study was carried out to investigate the dietary effects of Monascus pilosus mycelial extract on obesity in high-fat with cholesterol-induced obese rat models. It was observed that M. pilosus mycelial extract contains $25.85{\pm}1.98mg%$ of total monacolin K without citrinin by highperformance liquid chromatography (HPLC). The rats were randomly divided into 2 groups; normal control and a high-fat with cholesterol diet group. The high-fat with cholesterol diet group was fed a 5L79 diet with an added 15% lard and 1% cholesterol supplemented diet for 3 weeks for induction of obesity. After induction, obesity was confirmed by checking obesity indexes, the animals were divided into 4 groups (n=5); first, the normal control (NC), and then taken from the obese model of rats, a high-fat with cholesterol diet obesity control group (HF), 0.5% M. pilosus mycelial extract supplemented high-fat with cholesterol diet group (MPMs), 2% conjugated linoleic acid supplemented high-fat with cholesterol diet group (CLA) for 7 weeks. Body weight gains, obesity indexes, and body fat contents in the experimental groups (MPMs and CLA) were decreased compared with HF group. Feed Efficiency Ratio (FER) in MPMs was significantly lower than that of HF without change of feed intake. These results suggested that the anti-obesity effects of the M. pilosus mycelial extracts (MPMs) could prevent obesity induced by high-fat with cholesterol diet possibly via inhibition of lipid absorption.

This study was conducted to investigate the effect of fructooligosaccharide on intestinal flora, lipid metabolism and immune response. Thirty two male rats of Sprague-Dawley strain were divided into two groups according to body weight. Each group was fed the diet containing 2% cholesterol or the normal diet, respectively for 4 weeks. Each group was again divided into two sub-groups and they were fed with the diet containing 5% of sucrose and fructooligosaccharide, respectively for 8 weeks. The number of bifidobacteria slight increased, but not significantly, in oligosaccharide groups. Plasma total lipid concentration in cholesterol group was signficantly increased compared to the value in normal group. Dietary oligosaccharide decreased plasma total lipid concentration and triglyceride concentrations in normal group, but not in cholesterol group. Fecal lipid excretion was higher in cholesterol group than in normal group. Fecal cholesterol concentration in cholesterol-oligosaccharide group was significantly increased compared to other groups. Cholesterol had slight effects on TBARS and the immune status, but dietary oligosaccharide had no effects on these variables. The results in this study suggest that dietary oligosaccharide had no effect on serum and liver profiles of rats fed high cholesterol diet but increases the fecal cholesterol excretion.

Dongchunghacho rice, produced by cultivating Dongchunghacho fungus on rice, could be an effective functional food because it offers added value to rice and thus increases rice consumption. However, the physiological effect of Dongchunghacho rice has not been reported yet although there is increasing consumers demand. Therefore, we investigated the effect of Dongchunghacho rice (unpolished rice cultivated with Cordyceps militaris) on lipid metabolism in hyperlipidemic rats. Forty of 8 wk-old male Sprague-Dawley rats were divided into four groups after a 1 week of adaptation period and fed either a normal diet (66% polished rice diet, NC), high fat (12 g/100 g)-high cholesterol (1 g/100 g) diet with 53% polished rice (HC), or high fat-high cholesterol diets supplemented with 30% of the total rice as either unpolished rice (DR) or Dongchunghacho rice (DR). After 4 weeks, rats fed the Dongchunghacho rice diet with high fat and cholesterol had dramatically lower plasma LDL cholesterol concentrations and atherogenic indexes and higher plasma HDL cholesterol levels compared with the rats consuming polished rice or unpolished rice with high fat and cholesterol diet. Dongchunghacho rice led to less total lipid and total cholesterol accumulation in liver. However, these significant reductions in plasma or hepatic lipid profiles were not closely correlated with fecal total lipid or total cholesterol excretion. The plasma concentration of total cholesterol and triglycerides were not affected by Dongchunghacho rice. This hypolipidemic effect of Dongchunghacho rice seemed to be unrelated to unpolished rice itself, because the plasma and hepatic lipid profiles of DR group were not different from that of the HC group. These results suggest that unpolished rice containing cultivated Cordyceps militaris can improve plasma and hepatic lipid profiles in rats fed with high fat-high cholesterol diet.
