The effects of Cordyceps militaris on the weight gain, the food intake, the food efficient ratio, and the lipid concentrations of serum, liver, pancreas, heart and aorta in male rats fed cholesterol diet were studied. Male Sprague-Dawley rats were received 4 types of diets for 4 weeks, respectively : a normal diet(without cholesterol), a control diet(hypercholesterolemic diet), a hypercholesterolemic diet supplemented with 3% fruiting body of Cordyceps militaris(CF), a hypercholesterolemic diet supplemented with 3% mycelium of Cordyceps militaris(CM). The body weight gain of rats fed the control diet were significantly increased compared to those of the rats fed diets with CF or CM. But, the hepatic and pancreatic weights of rats fed diets with CF or CM were heavier than those of rats fed the normal diet. In serum of rats fed the CM diet, the concentrations of total cholesterol, triglyceride, LDL-cholesterol and the atherogenic index were significantly lower than those of rats fed the control diet. Also, serum HDL-cholesterol concentration and HDL-cholesterol/total cholesterol ratio were significantly lower in rats fed the control, CF or CM diets than those in rats fed the normal diet. Whereas, the hepatic concentrations of the total lipid, the total cholesterol and the triglyceride were significantly higher in rats fed 3 hypercholesterolemic diets than those in the rats fed normal diet. The heart and pancreatic concentrations of total cholesterol were the highest in the rats fed diet with the CR among rats fed experimental diets. In conclusion, the CM feeding decreased the concentrations of the cholesterol, triglyceride, and LDL-cholesterol and the atherogenic index in the serum of the rats. But the CF or CM feeding could not decrease the hepatic concentrations of the total lipid, cholesterol, triglyceride in the rats fed hypercholesterolemic diets.

The effects of taurine on plasma and liver cholesterol, erythrocyte ouabain sensitive Na efflux and platelet aggregation were examined in Sprague Dawley rats fed control or 0.5% cholesterol with 0.2% cholate diet. Plasma and liver levels of total cholesterol were increased significantly (p<0.05) in rats fed cholesterol diet compared to the control, and taurine significantly decreased the elevated plasma level of cholesterol in rats fed cholesterol diet (p<0.05). HDL-cholesterol was decreased in groups fed the cholesterol diet regardless of taurine supplementation and the difference between groups with and without cholesterol was significant (p<0.01). Plasma triglyceride was decreased and liver triglyceride was increased both significantly (p<0.05) in rats fed cholesterol compared to the control. Plasma and liver triglyceride in rats fed taurine was decreased significantly compared to the control (p<0.05). Intracellular Na tended to be lower in rats fed cholesterol or taurine and higher in rats fed cholesterol plus taurine compared to the control. Na efflux through Na-K ATPase and the passive leak of Na was somewhat reduced in rats fed cholesterol or taurine and was augmented in rats fed cholesterol plus taurine compared to the control, which showed a similar trend to the intracellular Na. Taurine supplementation caused a suppression of Na efflux in groups fed control diet and restored the suppressed Na efflux in groups fed cholesterol. Platelet aggregation was significantly decreased in the group fed taurine compared to the control (p<0.05) and the group fed cholesterol plus taurine was also a little lower in aggregation than the group fed cholesterol. Microscopic examination showed that taurine prevented fatty liver in rats fed cholesterol diet. Taurine known for stimulating Na-K ATPase in some cell types rather decreased erythrocyte ouabain sensitive Na-K ATPase in the present study. Taurine had hypolipidemic and hypocholesterolemic effects and inhibited platelet aggregation which may be favorable for prevention of cardiovascular diseases.

This study was designed to investigate the effect of age on the lipid metabolism in the rats fed different diets. In experiment A male Wistar rats of 5 weeks of age and of 32 weeks of age were divided into low fat diet groups and high fat-cholesterol groups. The rats were sacrificed 1 week, 2 weeks and 4 weeks after experiment begins. Also after 4 weeks. the rats in low and high fat diet groups were tube-fed 500mg of choelsterol and were sacrified 3 days later. In experiment b, male Wistar rats of 4 weeks of age and of 6 months of age were divided into 2 groups of butter and cron oil groups. And then eachgroup were divided into 2 subgroups ; meal feeding and nibbling groups . Each diet was fed for 4 weeks. In experiment A, age of the rats and experimental diets did not affect the serum cholesterol and triglycerides concentrations were higher in rats fed high fat cholesterol diet than in those fed low-fat or high -fat diets, but age of the animals had no effect on liver lipid content. The weight and cholesterol content of epidymal fat pad, however were higher in adult rats than in young ones regardless of the diets fed. When the rats were challenged with 500mg cholesterol, the rates of increase in serum and hepatic cholesterol level were higher in adult rats compared to young rats regardless of the diets . On the other hand, the rate of increase of small intestinal cholesterol content was lower in adult rats than in young rats. In experiment B, serum cholesterol and triglyceride content were relatively higher in young rats than adult ones. Stored body lipid was higher in adult rats, as judged by epididymal fat pad weight and total carcass lipid. Meal frequency and the kinds of fat in the diet did not affect the serum choelstero concentration . The serum triglyceride levels. however, was higher in butter fed rats thancron oil fed ones. The cholesterol content of live rand epididymal fat pad was lower in butter fed groups than corn oil groups for both young and adult rats, but there was no difference in liver triglycerides livel.

The purpose of this experiment was to study the effects of feeding egg yolk prepared from quail fed winged bean oil on plasma and liver cholesterol and fatty acids composition in rats. Eggs were collected from laying quails that had been fed diets containing 5% of either animal tallow, soybean oil, corn oil or winged bean oil. Yolk powders (referred to as winged bean yolk, soybean yolk, etc.) were prepared and fed at the 15% level to weanling female Wistar rats for 28 days. Rats fed winged bean yolk had significantly lower body weight gain than did rats fed soybean yolk or animal tallow yolk. There are no significant effects on plasma total cholesterol, liver cholesterol and triglyceride concentration due to feeding yolk powder containing different oil. However, LDL-cholesterol increased and HDL-cholesterol decreased in rats fed winged bean yolk. Liver lipid of rats fed with winged bean yolk had a higher linoleic but a lower linolenic content than did those fed animal tallow yolk. However, rats fed with winged bean yolk had a lower linoleic content than did rats fed soybean yolk or corn yolk. In conclusion, winged bean yolk seemed to have had an adverse effect on rats.

To investigate the effects mustard leaf(Brassica Juncea) on Cholesterol metabolism, male Sprague Dawley rate were fed semipurified diets containing 2% or 4% mustard leaf with or without cholesterol for 5 weeks. Plasma cholesterol content decreased significantly by feeding 4% mustard leaf with of without cholesterol for 5 weeks. Plasma cholesterol content decreased significantly by feeding 4% mustard leaf in rats fed 1% cholesterol in the diet. In addition, HDL-cholesterol increased slightly by the feeding of mustard leaf, resulting in a significant increase in the HDL-cholesterol/total cholesterol ratio and a reduction of atherosclerotic index. However, levels of plasma lipids were not influenced by mustared leaf in rats fed cholesterol-free diet. The contents of all classes of lipid in liver increased by dietary cholesterol. Of the liver lipids, triglyceride and cholesterol ester were accumulated most, showing a fatty liver synodrome. Supplementation of mustard leaf to cholesterol-containing diet resulted in a slight decrease in neutral lipid contents of liver. Fecal cholesterol excretion was higher by more than 2.7 and 3.3-fold in rats fed 2 and 4% mustard leaf than in control rats fed cholesterol. Similar trends were found in fecal bile salt excretion; rats fed and 4% mustard leaf excreted more bile salts by more than 1.5 and 2% than those fed control diet containing cholesterol. In summary, mustard leaf may have an antiatherogenci effect of reducing plasma cholesterol level and increasing HDL-cholesterol level. The plasma cholesterol lowering effect of mustard leaf is suggested to be due, at least in part, to increase in fecal excretion of cholesterol and bile acids.

The effects of nuruk and wheat bran on cholesterol level in serum and activities of free radical metabolizing enzymes were investigated in rats. The rats were fed a diet containing nuruk or wheat bran for one month. Body weight and food intake were measured. Animals were sacrificed after one month. The increased food efficiency ratio throughout whole growth period was observed in the rats fed with either nuruk containing Aspergillus terreus or wheat bran compared with control group on normal diet. In the rats fed with nuruk, hepatic GSH content, glutathione S transferase activity, hepatic cytochrome P 450 content, and aniline hydroxylase activities were generally increased. In the rats fed with nuruk containing other fungi except Aspergillus terreus, xanthine oxidase activity was decreased. The decreased cholesterol level in serum was observed in rats fed with nuruk prepared from Aspergillus terreus and wheat bran. LDL cholesterol level was decreased in rats fed with nuruk prepared with other fungi such as Penicillium sp. and Rhizopus sp. But HDL cholesterol level was increased in all groups fed with nuruk from any fungi and wheat bran. These results suggested that nuruk or wheat bran supplemented diet might exert their effect by decreasing cholesterol level in serum and amount of oxygen free radical level.

This study was conducted to investigate hypocholesteroloemic effect of garlic and onion in rats fed basal diet or cholesterol supplemented diets. Thirty Sprague Dawley rats were fed basal diet and 30 rats were fed basal diet plus 0.5% cholesterol, both containing none(control), 3% garlic or 3% onion for 4 weeks. Supplementation of 0.5% cholesterol significantly increased plasma and liver cholesterols(p<0.01) and liver triglyceride(TG) and plasma glucose(p<0.05). Plasma total cholesterol was significantly decreased in both garlic and onion groups compared to control when they were fed cholesterol supplemented diet(p<0.05). Plasm TG wa significantly decreased in onion groups regardless cholesterol supplementation (p<0.05). There were no differences in plasma glucose and HDL-cholesterol and liver total cholesterol and TG among groups in both basal and choleserol supplemented diets. Platelet aggregation was rather increased in onion group but not singnificantly different.

The study examined the effects of dietary green tea powder supplementation on blood glucose, and plasma and liver lipid concentrations in diabetic rats. Twenty-five male Sprague-Dawley rats (body weight $200{\pm}5\;g$) were divided into two groups (diabetic and non-diabetic), which were each randomly divided into two subgroups that were fed a control and 1% green tea powder-supplemented diet. Serum and liver lipid concentrations were measured by established techniques. Low density lipoprotein-cholesterol (LDL-C) was calculated from an established equation. Body weight gain and feed efficiency ratio were lower in diabetic rats than in non-diabetic rats regardless of diet. There were no differences in weight gain in diabetic and non-diabetic rats consuming the control and green tea powder-supplemented diets. The levels of fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index of diabetic rats were significantly higher than that of non-diabetic rats. Conversely, the levels of high density lipoprotein-cholesterol (HDL-C) of diabetic rats was significantly lower than that of non-diabetic rats. Fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index were significantly lower in diabetic rats fed the green tea powder diet than in rats fed the control diet, and HDL-C was significantly higher in rats fed the green tea powder diet than in rats fed the control diet. The content of liver total cholesterol and triglyceride of diabetic rats were significantly higher than that of non-diabetic rats. Liver total cholesterol and triglyceride were significantly lower in diabetic rats fed green tea powder-supplemented diet than in rats fed the control diet. It is concluded that green tea powder supplementation positively influences blood glucose and lipid metabolism in diabetic rats. The present study, although not directly applicable to humans, may have some implications for individuals who habitually consume green tea powder.
