  • This study was carried out to investigate the effects of the kinds and the amounts of dietary fiber on serum lipid composition in rats. Seventy-two male Sprague-Dawley rats weighting 160$\pm$10g were fed diets containing 1.0%, 3.6%, 6.0% and 10.0% $\alpha$-cellulose, pectin and alginic acid fer 4 weeks. Daily food intake of experimental groups was significantly higher in the u-cellulose 10.0% group than in the other groups. Increasing the dietary fiber level decreased the food efficiency ratio of the $\alpha$-cellulose, pectin and alginic acid groups. Serum triglyceride concentration was significantly lower in the rats fed the alginic acid diet. Serum total cholesterol concentration showed no significant difference in the kind and the amount of three dietary fibers. Serum HDL-cholesterol concentration was higher in $\alpha$-cellulose and pectin diet. HDL-cholesterol/total cholesterol ratio was higher in u-cellulose and pectin diet than alginic acid diet. In conclusion, alginic acid is good for the serum triglyceride decrease, pectin is good for HDL-cholesterol increase, $\alpha$-cellulose and alginic acid are good for HDL-cholesterol/total cholesterol ratio increase. But the different effects according to the dietary fiber's contents did not show a significant trend.

  • This study was carried out to investigate the effects of garlic vinegar supplementation on changes in body weight, blood glucose and serum triglyceride and cholesterol. Rats were fed a cholesterol-diet with or without garlic vinegar (20% garlic juice )supplement for 28days. Body weights in rats fed a diet containing garlic vinegar were significantly lower than those of control rats. The concentration of plasma glucose, total cholesterol . LDL-cholesterol , and HDL-cholesterol were not significantly different between the two groups for a period of up to four weeks. However, the concentration of plasma triglyceride was slightly decreased in the garlic vinegar-supplemented group. Results suggest that the supplementation of garlic vinegar is beneficial for weight reduction in high-cholesterol fed rats.

  • Fruits and vegetables reportedly have a protective effect against hyperlipidemia and oxidative disease. Accordingly, this study aimed to investigate the lipid-lowering effect and antioxidative capacity of persimmon leaf extract (PLE) in rats fed a high-cholesterol diet. Male rats were fed a high-cholesterol (1% wt/wt) or high-cholesterol diet supplemented with Lovastatin (0.02% wt/wt) or PLE (0.2% wt/wt) for 5 weeks. The concentration of plasma total cholesterol was significantly lower in the PLE group than in the lovastatin group. However, the concentration of plasma HDL-cholesterol and the ratio of HDL-cholesterol/total-cholesterol (%) were significantly higher in the PLE group than in the control group. The PLE supplement also significantly lowered the contents of hepatic cholesterol and triglyceride. In comparing fecal sterol contents, the PLE group saw a significant increase of both neutral and acidic sterol compared to the other groups. The PLE supplement significantly lowered plasma GOT and GPT activity, which ave indices of hepatic toxicity. Plasma TBARS concentration was significantly lower in the PLE group than in the control group, while hepatic TBARS level was not significantly different between the groups. In a comparison of hepatic antioxidant parameters, SOD, catalase and GSH-Px activity were significantly higher in the PLE group than in the control group. However, the PLE supplement significantly towered antioxidant enzyme activity in the erythrocyte. Furthermore, these results suggest that supplementation of PLE promoted the excretion of fecal sterols, thereby leading to decreased absorption of dietary cholesterol. In addition, PLE may play an important role in regulating antioxidative capacities by altering SOD and ChT activity.

  • The effects of soybean products(bean curd and curd residue) on the cholesterol profiles of serum and liver were studied in rats. Male rats were fed on purified diets, supplemented with cholesterol, containing casein (CAS), dried bean curd(DBC), or mixture of casein and dried bean curd residue(CBCD, 3:1, w/w) as a protein source for 4weeks. Dietary DBC and CBCD, compared with CAS, reduced markedly the concentration of serum cholesterol. The concentration of HDL-cholesterol was significantly higher in the CAS group than in the CBCD group, but there were no significant differences in the ratio of HDL-cholesterol to total cholesterol. Liver cholesterol was lower in the DBC group than in the CAS and CBCD groups. The results suggest an effective cholesterol-lowering action of soybean products in rats fed on cholesterolemic diets, and further a possibility that than curd dreg decrease the concentration of serum cholesterol, regardless of the presence of animal protein in diets.

  • In order to investigate the relationships of obesity in childhood to plasma lipid, blood pressure and blood glucose concentration, we selected 21 subjects for the moderate obese group(MO), 9 for mild obese group(MI), and 19 for the control group(C) among children aged 10~12. While the level of plasma triglyceride and VLDL-cholesterol of the MO group was much higher than that of group C, a significantly lower percentage of HDL-cholesterol was found in the MO compared to the percentage found in group C. Also the level of the total cholesterol and LDL-cholesterol of the MI group as well as the MO was much higher than that of C. The elevated total-cholesterol level of the Mi group was due to increased LDL-cholesterol and that of the MO was due to increases in both VLDL-cholesterol and LDL-cholesterol. As the result of these differences, the atherogenic index of the MO was significantly higher than that of C. The incidence of hypercholesterolemia( 200mg/dl) of the MI and MO was 60.0% and 77.8% respectively, All of the physical parameters and indexes except height were positively correlated with plasma lipid levels, systolic blood pressure, and blood glucose concentration. The analyses of the correlated with plasma lipid levels, systolic blood pressure, and blood glucose concentration. The analyses of the correlation indicated that central fat to peripheral fat ratio and waist to thigh girth ratio seemed to be closely associated to plasma lipid levels and atherogenic index. The MO had significantly higher systolic blood pressure than C and significantly higher blood glucose concentration was found in both MI and MO than in C. These results confirmed that obesity in childhood may be relevant to chronic metabolic diseases such as abnormal lipid metabolism, atherosclerosis, high blood pressure and diabetes mellitus.

  • This study was conducted to investigate the effect of water-soluble extract from roasted chicory on the lipid metabolism and oxidative stress in male Sprague-Dawley rats. The experimental groups were divided into three groups ; the normal group, the cholesterol group and the chicory group. Roasted chicory extract was supplemented at 5.0% (w/w) level in the cholesterol diet. Concentration of total cholesterol in serum was significantly higher in the cholesterol group than in the normal group, but this increase in the cholesterol group was significantly decreased by the cholesterol diet supplemented with chicory extract. Concentration of HDL-cholesterol in serum was significantly lower in the cholesterol group than in the normal group, but this decrease in the cholesterol group tended to increase in the chicory group. However, concentrations of triglyceride, phospholipid and nonesterified fatty acid in serum were not significantly different among the groups. Concentrations of triglyceride and cholesterol in liver were significantly higher in the cholesterol and chicory groups than in the normal group. Feces weight and the excretion of cholesterol and bile acid into feces were significantly higher in the chicory group than in other groups. Concentrations of thiobarbituric acid reactive substances (TBARS) in homogenates and microsomal fractions of liver were not significantly different among the groups. On the other hand, concentration of 8-hydroxydeoxyguanosine (8-OHdG) as an useful marker of oxidative stress in urine was lower in the chicory group than in other groups. Concentration of serum glucose was signnificantly lower in the cholesterol group than in the normal group, but that of the chicory group was significantly higher than in the normal group. These results demonstrated that dietary chicory extract exerted the decreasing effect of cholesterol level and oxidative stress in cholesteral-fed rats.

  • This study was designed to investigate the optimum recommendation level on Gatrodia rhizoma and the effects on the improvement of the lipids in the dietary hypercholesterterolemic rats. Experimental diets mixed with 5% Dioscorea batatas(Group 2), 10% Dioscorea batatas(Group 3), 15% Dioscorea batatas (Group 4) 5% Gastrodia rhizoma (Group 5), 10% Gastrodia rhizoma (Group 6), and 15% Gastrodia rhizoma (Group 7), were administered to the male rats of the Sprague Dawley for 3 weeks. Concentration of total cholesterol in serum was lower in the Gastrodia rhizoma groups than in the other groups, especially total cholesterol concentration of 10% Gastrodia rhizoma(Group 6) was the lowest in the Gastrodia rhizoma groups. Concentration of HDL-cholesterol in serum was higher in the 10% Gastrodia rhizoma and 15% Gastrodia rhizoma than in the other groups. Concentrations of cholesteryl ester, LDL, LDL-cholesterol in serum were the lowest in the 10% Gastrodia rhizoma. Concentration of glucose and activity of GPT in serum were the lowest in the 10% Gastrodia rhizoma group. The activity of GOT in serum was lower in the 10% Gastrodia rhizoma group and 15% Gastrodia rhizoma group than in the other groups. Therefore, we consider that there are effects on the improvement of the lipids in the Gastrodia rhizoma and the optimum recommendation quantity of Gastrodia rhizoma is 10% to quantity of food composition.
