  • The effects of diet induced hyperlipidemia on kidney function were studied in Sprague-Dawley rats fed high fat diet containing 20% beef tallow and high cholesterol diet containing 5% cholesterol for 8, 12, 16 weeks, respectively. The concentrations of serum total lipid, total cholesterol and LDL-cholesterol were significantly high cholesterol diet groups during all experimental periods (p<0.05). HDL-cholesterol concentration was the lowest value in high cholesterol diet group of 16 weeks(p<0.05). Triglyceride concentration was not affected by experimental diets. Serum total protein, albumin and creatinine concentration tended to higher in high cholesterol diet groups than those in high fat diet groups. And serum urea-N concentration was higher in high fat diet group of 16 weeks than that in other diet groups. Urinary total protein and urea-N were higher in high cholesterol diet groups than those in other diet groups regardless of experimental period period. There was no significant difference in urinary creatinine concentratin among diet groups(p<0.05). GFR was lower in high cholesterol diet groups than that in high fat diet groups at 8, 16 weeks, respectively. Wet weight per body weight, total lipid, triglyceride, total cholesterol concentations of liver tissue were apparently high in high cholesterol diet groups(p<0.05). Kidney wet weight per body weight wer not affected by experimently diets, total lipid concentration of kidney tissue was significantly high in high fat diet groups of 12 weeks(p<0.05), kidney tissue triglyceride concentrations of high cholesterol diet groups of 12, 16 weeks apparently low, and total cholesterol concentration of kidney tissue was higher in experimental diet groups than that of control groups at 12, 16 weeks(p<0.05). Fecal excretion, total lipid, triglyceride and cholesterol concentrations of feces were markedly high in all high cholesterol diet groups except high fat diet group of 16 weeks. The results of light microscopic examination indicated that glomerulosclerosis was not obsrved in rats fed experimental diets.

  • The effects of indigestible dextrin on lipids in serum, tissue, and feces were investigated in two experiments carried out with 64 male Sprague-Dawley rats for eight weeks. Experiment I diet(normal fat diet) containing 5% corn oil and experiment II diet(high fat diet) containing 18% fat(13% beef tallow and 5% corn oil) and 1% cholesterol were divided into four groups with 0.5% cellulose(0.5CL : control), 10% cellulose(10CL), 10% Indigestible dextrin I(ID-I) and 10% indigestible dextrin II(ID-II), respectively. ID-I and ID-II diets produced a decrease in serum total lipid and cholesterol concentrations in both normal and high fat diets but more significantly in the groups fed high fat diet. ID-I, ID-II, and 10CL of high fat diet decreased serum glucose concentration. ID-I and ID-II diets also decreased liver cholesterol and triglyceride concentrations in rats fed normal and high fit diets. The fecal excretion of cholesterol in ID-II/high fat diet was significantly higher than that of 0.5CL diet. Bile acid excretion was increased in the rats fed 10CL and ID-II diets of normal and high fat diets. These observations indicat the hypolipidemic and hypocholesterolemic effects of indigestible dextrin on the rats. These effects are mediated by the increase of facal cholesterol and bile acid excretion. (Korean J Nutrition31(6) : 981-990, 1998)

  • 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 effects of shellfish hydrolysate on lipid metabolism in rats fed high fat diet. Male Sprague-Dawley rate weighting approximately 110g were fed basal control diet, high fat diet and high fat diet plus 4 different shellfish hydrolyates for 4 weeks. The shellfish hydrolysates from the different sources, were oyster, hard-shelled mussel, little neck clam and march clam. After 4 weeks, serum GOT, GPT, ${\gamma}$-GTP, triglyceride and total cholesterol was significantly decreased in shellfish hydrolysates supplementation with high fat diet compared to basal control and high-fat group(p<0.05). The total lipid and cholesterol content in liver showed significant decrease(p, 0.05). There were no different in serum GPT, HDL-cholesterol, liver total cholesterol and lipid of rats between basal control diet and high-fat diet. The unsaturated fatty acids, specific components of shellfishes were a little components in shellfish hydrolysate as they were a low and not different among the groups and were most well reflected in liver and plasma. Considering digestive and absorptive process of in human body, it was assumed that the hypolipidemic effect of shellfish was not under the influence of unsaturated fatty acids but the other components, peptides, taurine and betaine and so on was detected in the process of hyperlipidemia induced by high-fat diet.

  • The effects of the fruiting body of Agaricus blazei Murill on the weight gains, food intakes, food efficiency ratios, serum and hepatic lipids concentrations were investigated in male rats. Sprague-Dawley rats, 21 weeks old, were given four different types of diets for a succeeding period of 10 weeks: either a normal diet (5% corn oil), a high fat diet (high fat; 20% lard), a 3% or 5% Agaricus diet (high fat diet+3% or 5% Agaricus powder). The body weight gains and food efficiency ratios of the rats fed 5% Agaricus diet were significantly lower than those of the rats fed high fat diet. The hepatic and kidney weights of the rats fed Agaricus diets were similar to those of the rats fed high fat diet. The epididymal fat pad weights of the rats fed 3% or 5% Agaricus diets were significantly lower than those of the rats fed high fat diet. The concentrations of hepatic and serum triglyceride in the rats fed 5% Agaricus diet were significantly lower than those in the rats fed high fat diet. But the hepatic total cholesterol of rats fed the 3% or 5% Agaricus diets were similar to those of rats fed the high fat diet. The concentrations of serum total cholesterol, LDL-cholesterol and atherogenic index in rats fed the 3% or 5% Agaricus diets were significantly decreased compared with those of rats fed the high fat diet. The HDL-cholesterol/total- cholesterol ratios of the rat fed 3% or 5% Agaricus diet were significantly increased compared with those of rats fed the high fat diet. There were no differences in serum concentrations of HDL-cholesterol and phospholipid among the experimental groups. These results showed that the 5% Agaricus diet feeding decreased the total cholesterol, the triglyceride, the LDL-cholesterol and the atherogenic index, and increased the HDL-cholesterol/total-cholesterol ratio in serum of rats.

  • This study was carried out to investigate the effect of Meristotheca papulosa on lipid concentration of serum and liver in rats fed high fat diet for 4 weeks. Experimental groups ere divided into normal group (5% corn oil), high fat diet group (5% corn oil+20% lard), high fat diet and 5% or 10% Meristotheca papulosa treated group. The weights of kidney, heart and tests were not significantly different among the group, but weight of liver was significantly decreased by supplement of Meristotheca papulosa (10%). The contents of serum total lipid, trigly-ceride, total cholesterol, free cholesterol, cholesterol ester and atherogenic index were decreased, while HDL-cholesterol was increased by Meristotheca papulosa supplementation compared to high fat diet group. Meristotheca papulosa supplement has obvious effects on lowering hepatic total lipid, triglyceride and total cholesterol. Our findings suggest that Meristotheca papulosa supplement can improve lipid metabolism in high fat fed rats.

  • This study was conducted to investigate the hypocholesterolemic effects of porphyran and insoluble dietary fiber isolated from laver in rats fed high fat diet containing 1% cholesterol, 0.25% sodium cholate and 12% lard. Rats were fed, ad libitum, diets containing 5% diet fiber as cellulose(normal control or high fat control), porphyran or insoluble dietary fiber for 4 weeks. Among the groups fed high fat diet, liver weight was significantly lower in high fat porphyran group than high fat control. Plasma GOT, GPT, total cholesterol, cholesteryl ester, LDL-cholesterol and liver total cholesterol concentration were significantly lower in high fat porphyran group than high fat control. The feeding of porphyran significantly increased fecal cholesterol and bile acid excretion. The feeding of insoluble dietary fiber had no significant effect on either plasma or liver cholesterol levels, although fecal cholesterol level in the insoluble dietary fiber group was significantly higher than that in the high fat control. The results indicate that porphyran isolated from the laver may exert their hypocholesterolemic effect by increasing excretion of fecal bile acid and cholesterol.

  • The effects of liquid culture of Agaricus blazei Murill on the weight gains, serum and hepatic lipid concentrations were studied in male rats. Sprague-Dawley rats (7 weeks old) were given four different types of diets for 6 weeks, respectively: a normal diet group, a high fat control diet group (normal diet+15% lard +0.5% cholesterol), a 30% or 40% A. blazei diet groups (high fat control diet+30% or 40% A. blazei in water) according to the levels of A. blazei supplementation. The body weight gains, food intake, food efficiency ratios, and the liver, kidney, and epididymal fat pad weights of the rats fed 30% or 40% A. blazei diets were similar to those of the rats fed high fat control diet. The concentrations of serum total cholesterol, LDL-cholesterol and atherogenic index in rats fed the 30% or 40% A. blazei diets were significantly decreased compared with those of rats fed the high fat control diet. The HDL-cholesterol/total-cholesterol ratios of the rats fed 30% or 40% A. blazei diet were significantly increased compared with those of rats fed the high fat control diet. The fecal excretion of total lipid . in the rats fed 40% A. blazei diet was significantly increased compared with those of rats fed the high fat control diet. The concentrations of serum total lipid in the rats fed 40% A. blazei diet was significantly lower than that in the rats fed high fat control diet. But the concentrations of serum HDL-cholesterol, hepatic total cholesterol and triglyceride of rats fed the 30 or 40% A. blazei diets were similar to those of rats fed the high fat control diet. These results showed that the 30 or 40% A. blazei diets feeding decreased the total cholesterol, LDL-cholesterol and atherogenic index, and increased the HDL-cholesterol/total-cholesterol ratio in serum of rats.

  • 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.
