  • Among the many deleterious effects of cardiopulmonary bypass[CPB], deterioration of plasma lipoprotein is a significant problem. Break-down of lipoprotein releases free fatty acids into the systemic circulation which, in turn, can cause microembolism. This study conducted on 30 patients undergoing CPB, was designed to elucidate the changes of plasma lipoproteins during and after CPB. Blood samples were taken at pre-CPB, on-CPB 30 minutes and 60 minutes, postoperative 1st, 3rd, 7th days. The levels of total cholesterol and triglyceride were measured and lipoprotein was subdivided into three kinds on electrophoresis. During CPB, the amounts of plasma total cholesterol and triglyceride decreased significantly and were recovered to pre-CPB levels after postoperative third day. There was no significant correlation between the duration and the severity of decrease in plasma total cholesterol and triglyceride levels. During CPB, the fraction of VLDL decreased and that of LDL increased. After cessation of CPB, the fraction of LDL decreased and that of HDL increased. After postoperative 1st day, the fraction of HDL decreased and that of LDL increased.

  • The present study was conducted to evaluate the effect of dietary levels of vitamin A on the lipid composition in rats fed Zn-deficient diets. Fifty male Sprague-Dawley rats were fed 5 experimental diets for 7 weeks. Rats were fed Zn-and vitamin A-deficient diet or the same diets supplemented with various levels of vitamin. A liver total lipid, cholesterol and triglycerides contents tended to decrease in Zn-deficient rats, but the supplementation of excess vitamin A enhanced those contents. Plasma cholesterol content was significantly higher in feeding Zn-deficient and excess vitamin A diet. Plasma triglyceride and phospolipid contents were higher in Zn-deficient groups, but not influenced by dietary levels of vitamin. A . Plasma HDL-cholesterol content was not changed by Zn-deficient diets. Plasma alkaline phosphatase activity was significantly reduced in Zn-deficient groups. Zinc contents of plasma and liver were influenced by the dietary level of zinc, but not changed by supplementation of vitamin A.

  • 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.

  • This study was carried out to examine whether kimchi has hypolipidemic effect and to know how it exert lipid-lowering effect in rats. Male Sprague-Dawley rats were fed with kimchi-fee diet, or 3%, or 5%, or 10% kimchi diets for 6 weeks. Plasma cholesterol level was lowered in rats fed all concentrations of kimchi diets, and plasma triglyceride(TG) level was lowered in 10% kimchi diet group compared with that of control significantly(p<0.05). Th intake of kimchi lowered VLDL-cholesterol and VLDL-TG levels, whereas increased HDL-cholesterol level significantly(p<0.05). LDL-cholesterol level was lowered only in 5% kimchi diet group and LDL-TG level was lowered in all kimchi diet groups compared with those of control significantly (p<0.05). the intake of 5% and 10% kimchi diets also lowered the levels of hepatic cholesterol, TG, total lipid, and apolipoprotein B, whereas increased the levels of fecal total fat, cholesterol, TG, and apolipoprotein A-1 significantly(p<0.05). Triiodothyronine(T$_3$) level was elevated in rats fed kimchi diet, whereas thyroxine(T$_4$) level was not affected by kimchi treatment. These observations support that the intake of kimchin in rats loweres plasma and hepatic lipid levels by increasing the excretion of TG and cholesterol through feces, by the elevation of T$_3$ level, and by the altered lipoprotein metabolism.

  • The purpose of this study was to observe the effects of cellulose and pectin on glucose and plasma lipid concentrations in healthy women. Eight female collage students were participated voluntarily. All subjects received a fiber-free control diet (CD), cellulose diet (CED), pectin diet (PTD) with each diet for a period of three days with a 4 day interval. The food intake of subjects were monitored every day and plasma level of glucose, triglyceride, total cholesterol were determined at last day. Blood glucose, plasma triglyceride, total cholesterol were measured at fasting state and 30, 60, 90, 120, and 180 minute after consuming each diet. Plasma glucose concentrations (AUC: Area Under the Curve) of pectin diet was $122.7{\pm}4.0mg/dl$ and that of cellulose diet was $147.6{\pm}8.4mg/d$, but they were significantly lower than in comparison with those of control diet ($197.1{\pm}11.6mg/dl$) (p<0.05) Plasma triglyceride concentrations of the CED ($-83.9{\pm}22.2mg/dl$) PTD ($-9.7{\pm}26.1mg/dl$) showed gradual decrease after each test diet feeding but not significantly different in each dietary fiber added diet (p<0.05). Plasma cholesterol concentrations of the CD was not significantly different in PTD, but PTD was significantly lower than the CED until 3 hours after consuming each test meal (p<0.05). In conclusion, in spite of total cholesterol was reduced only by pectin, glucose and triglyceride were lower than control diet in dietary fiber intake. But there were no significant differences each dietary fiber.

  • The purpose of this was to analyse zinc intakes and effect of Zn(30mgZnSO4/day) supplementation on plasma zinc level, serum HDL-cholesterol and serum Alkaline Phosphatase (AP) activity of Korean adults. The men consumed 8.52($\pm$2.08)mg of zinc, and the women consumed 6.4($\pm$2.62)mg of zinc. Although protein intakes of subjects were lower than normal values. The first source of zinc was cereal and grain group, the second was meat, fish, egg and soybean group. Two food groups supplied about 80% of zinc. After two weeks of zinc supplementation, the zinc concentration in plasma was significantly increased. The highest plasma zinc level was 78.80ug/dl(men), 76.04ug/dl(women) at 2 weeks after zinc supplementation(p<0.05). Serum DHL-cholesterol was significantly decreased by zinc supplementation. The lowest serum HDL-cholesterol level was 39.29mg/dl(men), 44.84mg/dl(women) at 4 weeks after zinc supplementation(p<0.01). Serum AP activity was significantly increased by zinc supplementation. The highest AP activity was 86.40units/L(man), 67.93units/L(women) at 2 weeks after zinc supplementation(p<0.05). It seems that the supplementation of 30mg ZnSO4/day can be beneficial for improving zinc nutriture. However it can be negative factor on coronary heart disease because serum HDL-cholesterol was significantly decreased(p<0.01)

  • Objectives : The purpose of this study is to find out the effect of antioxidation related to aging of Cheongeumyeonsudan which is written on Dongui-bogam experimentally. Method : 14 weeks aged SD albino rats were separated into uncontrolled group, controlled group and CGY group. As controlled and CGY groups were induced aging by subcutaneous injection of D-galactose, at the same time we administered the extract of Cheongeumyeonsudan to CGY group for 6 weeks. After then we drew blood from each group, and took measurements; the activity of SOD, GSH-px, catalase in erythrocytes, TBARS value, concentration of total lipid, tryglycende, total cholesterol, HDL-cholesterol in blood plasma. Results : The activities of SOD, GSH-px in erythrocytes were significantly increased in the CGY group compared with control group. The activity of catalase showed a tendency to increase, but it was nor remarkable. The concentration of total lipid, the values of TBARS and total cholesterol was significantly decreased in the CGY group compared with control group, and the concentration of plasma HDL-cholesterol was not remarkable. The concentration of tryglycende in plasma showed a tendency to decreased. Conclusions : it is suggested that Cheongeumyeonsudan decreased the activities of free radical, the concentration of lipid in plasma and generate enzyme which form lipid peroxide.

  • Lipid peroxidation (LPO) has been identified as an important component of atherosclerosis. In this study, the effects of supplementation with cholesterol (0.5%), olive oil (5%) and vitamin E (0.05%) on erythrocyte glutathione (GSH), plasma malondialdehyde (MDA), total cholesterol, HDL-LDL cholesterol and triacylglycerol, brain and liver MDA and GSH concentrations of rats were investigated. A total of 50 Sprague-Dawley male rats aged 6 months, and of equal body weight were used and fed a standard ration ad libitum. Animals were housed in the University of Selcuk, Veterinary Faculty Experimental Animals Unit. The experiment lasted 60 days and there were five experimental groups as follows: 1. Control, 2. Cholesterol (0.5%), 3. Olive oil (5%), 4. Cholesterol plus vitamin E (0.05%), 5. Olive oil plus vitamin E (0.05%). At the end of the experiment, blood samples were taken by cardiac puncture and erythrocyte GSH, plasma MDA, cholesterol, HDL-LDL cholesterol, triacylglycerol and also GSH and MDA concentrations in brain and liver tissue of rats were spectrophotometrically determined. Supplementation of olive oil and cholesterol into rat diets (groups 2 and 3) caused significant differences in lipid parameters; HDL cholesterol concentrations were increased in the olive oil group and LDL cholesterol was lower than in the cholesterol fed group. Moreover, these decreases in LDL and triacylglycerol concentrations were more significant with vitamin E supplementation. The high plasma MDA concentrations showed that lipid peroxidation occurred in the olive oil group and the highest brain MDA concentrations were determined also in the olive oil group. These findings suggest that vitamin E addition may decrease the sensitivities of several oils to oxidation and that monounsaturated fatty acids in olive oil may decrease the incidence of atherosclerosis by regulating blood lipid profiles.
