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)

Objectives : This study was designed to investigate the effect of water extract from Paeonia Lactiflora Pasll. with medicinal herb on plasma lipid and glucose in rats fed high fat diet. Methods : Experimental groups were divided into control diet group(C), high fat diet group(HF), high fat diet and 5% water extracts from Paeonia Lactiflora Pasll. with medicinal herb group(HFE I), high fat diet and 10% water extract from Paeonia Lactiflora Pasll. with medicinal herb group(HFE II). Weight gain, food intake, food efficiency, plasma lipid concentration and glucose were determined for 10 weeks during high fat diet. Results : In this experiment, body weight and food efficiency were significantly increase in high fat diet. High fat diet group showed elevated levels of total cholesterol, LDL-cholesterol and free fatty acid. Consumption of 10% water extract Paeonia Lactiflora Pasll. with medicinal herb lowers level of total cholesterol, LDL-cholesterol and free fatty acid. But levels of plasma triglyceride, HDL-cholesterol and glucose did not affect by high fat diet and water extract Paeonia Lactiflora Pasll. with medicinal herb Conclusions : In these results, water extract Paeonia Lactiflora Pasll. with medicinal herb in high fat diet group decreased plasma total cholesterol, LDL-cholesterol and free fatty acid. Thus the Paeonia Lactiflora Pasll. with medicinal herb might be useful in the treatment of hyperlipemia.

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.

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.

The purpose of the present study was to evaluate the effects of red pepper seeds powder on lipid metabolism in rats fed high fat high cholesterol diet. Rats were divided into five experimental groups: normal diet group, high fat high cholesterol diet group, high fat high cholesterol diet with 5% red pepper seeds powder supplemented group (SA group), high fat high cholesterol diet with 10% red pepper seeds powder supplemented group (SB group) and high fat high cholesterol diet with 15% red peeper seeds powder supplemented group (SC group). The serum triglyceride (TG) and cholesterol contents, and LDL-cholesterol and atherogenic index (AI) of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The serum HDL-cholesterol contents of the red pepper seed powder supplemented groups were increased compared to the HF group. However, there was no significant difference in the serum HDL-cholesterol among all experimental groups. The hepatic TG and cholesterol contents of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The fecal total cholesterol and triglyceride contents of the red pepper seeds powder supplemented groups were significantly increased compared to the HF group. These results suggest that supplementation of red pepper seed powder may have a pronounced impact on markers of lipid metabolism in serum and liver of rats fed high fat high cholesterol diets.

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.

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.
