  • The study was performed to investigate the effects of isoflavone and/or grape seed oil supplementation on serum and liver lipid profiles and bone strength in ovariectomized female rats. Female Spraque-Dawley rats were assigned into 4 groups of ovariectomized (O), isoflavone (0.085 mg/100 g b.w/day) in ovariectomized rats, grape seed oil in ovariectomized rats and isoflavone and/or grape seed oil in ovariectomized rats. After 8 weeks, biochemical profiles of serum, liver and bone were analyzed. Total food intakes, body weight gains and FER (food efficiency ratio) were not statistically significantly different among groups. Total cholesterol, triglyceride and LDL-cholesterol levels in serum were decreased by fed of isoflavone and/or grape seed oils. However, crude lipid and total cholesterol contents in liver were not affect of isoflavone and/or grape seed oil. The hepatic glutathione contents were increased by isoflavone and/or grape seed oil fed. The hepatic glutathione-S-transferase activity in isoflavone and/or grape seed oil supplemented groups were higher than that O group. Bone (scapular and femur bone) dry weight, femur of max weight and bending strength were no significant difference among groups. Our finding suggest that isoflavone/grape seed oils might have potential role for serum lipid profiles improvement and bone strength in vivo.

  • This study investigated the effects of Platycodon grandiflorum aqueous extract on lipid concentration of serum and liver in rats fed high cholesterol diet Male Sprague-Dawley rats were assigned to three groups (control, low dose of extract, high dose of extract) for four weeks. The serum total cholesterol concentration was significantly lower in the low and high doses of extract groups than in the control group. There was a significant decrease in the free cholesterol, cholesterol ester, LDL-cholesterol, and triglycerides concentrations in serum, and the total cholesterol and the triglycerides contentin liver in the low and high doses of extract groups compared to the control group. When the serum phospholipid concentration was compared among the groups, it was significantly lower in high dose of extract group than in control and low dose of extract group. It can be postulated that Platycodon grandiflorum aqueous extract may possess substantial hypolipidemic properties in rats.

  • This study was performed to investigate the effect of dietary $\beta$-carotene supplementation on lipid peroxide levels and antioxidant enzyme activities in alcoholic fatty liver rats. Forty five Sprague-Dawley male rats aging 8 weeks were used as experimental animals, which were divided into the control diet (CD) and the ethanol diet (ED) and the ethanol + $0.02\%$ $\beta$-carotene diet (EPD) groups and fed the experimental diet respectively for 5 weeks. After the feeding, rats were sacrificed to get blood and liver to analyze lipid and lipid peroxide levels and antioxidant enzyme activities. The mean body weight and food intake of the ethanol diet group was significantly lower than that of the control diet. The liver index (LI) of the ethanol diet group was significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Serum levels of total lipid, triglyceride of the ethanol diet group were significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Total cholesterol levels were not significantly different among all groups. HDL-cholesterol of the ethanol diet group was significantly lower than those of the control diet and the $\beta$-carotene supplementation group. Liver TBARS of the ethanol diet group was significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Liver lipofuscin and conjugated diene levels were not significantly different among all groups. The superoxide dismutase activity of the ethanol diet group was significantly lower than those of the control diet and the $\beta$-carotene supplementation group. Catalase and glutathione peroxidase activities were not significantly different among all groups. Because v-carotene supplementation significantly decrease the serum total lipid, triglyceride, liver TBARS revels and increase the superoxide dismutase activity in alcoholic ratty liver rats, $\beta$-carotene supplementation seems to give beneficial effect for the alcoholics.

  • The aim of the study was to determine whether vitamin E supplementation in three experimental model rats with impaired glucse tolerance could change serum insulin concentration and lipid distribution. The three groups were adult(AS) and neonatal (NS) streptozotocin-induced groups, and a high sucrose diet(HS) group. Each group was divided into control and vitamin E supplementatino groups at the age of 9 weeks. The level of vitamin E supplementation was 5g/kg diet. Blood and organ samples were taken at 5 and 10 weeks and were examined for changes in the level of serum insulin, glucose, lipids, liver lipids, and oxidative status. Vitamin E supplementation significantly reduced serum insulin in the HS group and caused the significant beneficial changes in serum lipids and triglycerides in As grouop at 10 weeks . In all groups, serum vitamin E was increased and malondialdehyde(MDA) in serumand liver were decreased significantly by vitamin E supplementation. The results suggest that vitamin E supplementation improves lipid distribution in adult streptozotocin-induced rats and serum insulin concentration in high sucrose diet-induced rats. Vitamin E might prevent on reduce oxidative injury in all experimental model rats with impaired glucose tolerance.

  • The experiments were performed to investigate the effects of protein and protein hydrolysates on lipid metabolism in the hyperlipidemic/hypercholesterolemic rat model induced by feeding fat-enriched diet. In Except 1 male rats were fed four semi-purified high fat and cholesterol diets that contained different nitrogen source, casein(C), casein hydrolysate(CH), corn gluten(G) and corn gluten hydrolysate(GH), for 6 weeks. In Expt. 2 rats were fed high fat and cholesterol diet for 4 weeks to induce hyperlipidemia and hypercholesterolemia. Then the rats were divided into 4 groups and were fed the four kinds of above experimental diets for 4 weeks consecutively. The contents of total lipid , cholesterol and triglyceride in blood, liver and feces were determined. Serum lipid concentrations of CH, G and GH were significantly lower than that of C. Serum cholesterol concentrations of hydrolysate groups(CH and GH) were significantly lower than those of intact protein groups(C and G). Serum HDL -cholesterol concentration tended to increase by hydrolysate intake. The total lipid, cholesterol contents in liver showed similarity results as above. Fecal lipid excretions of CH, G, and GH groups were significantly higher than that of C group. These results indicate that hypolipidemic and /or hypocholesterolemic effect of corn gluten or protein hydrolysates were detected in the process of inducing hyperlipidemia by high-fat and cholesterol diet or after inducing hyperlipidemia.

  • This study was performed to investigate the effect of various levels of Zn(0, 30, 3000 ppms) and different kinds of lipid(corn oil, sesame oil or butter.) in the diet upon lipid metabolism and Zn & Cu concentration in various organs and tissues in weanling rats. The results obtained were summarized as following : 1) Food consumptions, body weight gains and F.E.R.s showed no significant differences among groups. 2) The contents of total lipids and total cholesterols in serum tended to increase with increase in lipid saturation and Zn levels. Those in per g liver were higher in butter groups and tended to be higher in low Zn groups. Total lipids contents in per g muscle tended to be higher in butter and high Zn groups, but total cholesterols contents in per g muscle tended to be higher in corn oil and low Zn groups. 3) Liver, serum and fecal Zn concentrations tended to be higher in high Zn groups than other Zn groups. The Cu concentrations in liver and serum tended to be lower in high Zn groups. On the contrary, the Cu concentrations in urine tended to be higher in high Zn groups.
