  • This study was designed to investigate the effect of dietary Platycodon grandiflorum on plasma glucose and lipid metabolism in $KK-A^y$ mice and STZ-induced diabetic rats. Both plasma triglyceride and plasma cholesterol levels in STZ-induced diabetic rats were significantly decreased by dietary Platycodon grandiflorum feeding for 4 weeks compared to those of control rats, but there were no marked differences in $KK-A^y$ mice. However, for plasma glucose values, Platycodon grandiflorum feeding resulted in a significant decrease in both STZ-induced diabetic rats and $KK-A^y$ mice. Also, dietary Platycodon grandiflorum slightly decreased the postprandial glucose level at 30 and 60 mins during oral glucose tolerance test in $KK-A^y$ mice. Although there was no statistical significance, the fasting plasma insulin levels of Platycodon grandiflorum dieted $KK-A^y$ mice tended to decrease when compared to that of control mice. Therefore, the present results suggested that dietary Platycodon grandiflorum may have a beneficial effect on preventing hypercholesterolemia and hyperlipidemia.

  • This study was conducted to investigate the effect of fructooligosaccharide on intestinal flora, lipid metabolism and immune response. Thirty two male rats of Sprague-Dawley strain were divided into two groups according to body weight. Each group was fed the diet containing 2% cholesterol or the normal diet, respectively for 4 weeks. Each group was again divided into two sub-groups and they were fed with the diet containing 5% of sucrose and fructooligosaccharide, respectively for 8 weeks. The number of bifidobacteria slight increased, but not significantly, in oligosaccharide groups. Plasma total lipid concentration in cholesterol group was signficantly increased compared to the value in normal group. Dietary oligosaccharide decreased plasma total lipid concentration and triglyceride concentrations in normal group, but not in cholesterol group. Fecal lipid excretion was higher in cholesterol group than in normal group. Fecal cholesterol concentration in cholesterol-oligosaccharide group was significantly increased compared to other groups. Cholesterol had slight effects on TBARS and the immune status, but dietary oligosaccharide had no effects on these variables. The results in this study suggest that dietary oligosaccharide had no effect on serum and liver profiles of rats fed high cholesterol diet but increases the fecal cholesterol excretion.

  • BACKGROUND/OBJECTIVES: The present study was conducted to investigate the effects of dried Momordica charantia aqueous extracts (MCA) and ethanol extracts (MCE) on obesity and lipid profiles in mice fed a high-fat diet. MATERIALS/METHODS: Forty two ICR mice were randomly divided into six groups. The normal group was fed a basal diet, and other groups were fed a 45% high-fat diet (HFD) for 7 weeks. The normal and HFD groups were also orally administered distilled water each day for 7 weeks. The remaining groups received Momordica charantia extract (0.5 or 1.0 g/kg/day MCA, and 0.5 or 1.0 g/kg/day MCE). In order to measure the anti-obesity and lipid profile improvement effects, body and visceral tissue weight, lipid profiles, plasma insulin levels, hepatic malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity were measured. RESULTS: Both MCA and MCE significantly decreased body and visceral tissue weight relative to those of the HFD group (P < 0.05). Additionally high doses of MCE and MCA significantly reduced the plasmatic insulin levels compared to the HFD groups (P < 0.05) to concentrations comparable to those found in the normal group. MCA and MCE supplementation also significantly modulated the lipid profiles in plasma, liver, and feces compared to mice fed the HFD (P < 0.05). Furthermore MCA and MCE significantly increased hepatic SOD activity, and reduced MDA generation in the liver of the HFD mice (P < 0.05). CONCLUSIONS: Results from the present study suggest that Momordica charantia extracts have anti-obesity effects and the ability to modulate lipid prolife of mice fed a HFD by suppressing body weight gain, visceral tissue weight, plasma and hepatic lipid concentrations, and lipid peroxidation along with increasing lipid metabolism.

  • The incorporation of activity in plasma lipid was determined after injection of $u-C^{14}-glucose$ to normal laying hen. The extraction of total lipid from plasma was carried out by the method of Floch et al. with some modifications. The counting of carbon-14 activity was conducted by a Beckman Liquid Scintillation System, The concentration of plasma lipid was estimated as much as 3,070mg per 100ml of plasma taken at 5 minutes after injection of tracer amount of $u-C^{14}-glucose$. The specific activity per gram of plasma lipid carbon atom per injected dose per kg body weight increased gradually following the time after injection until 120 minutes, whereas the glucose activity decreased logarithmically. The partial incorporation quotient of activity in plasma lipid from that of glucose was 0.73% until 120 minutes after the injection.

  • It has been suggested that green juice supplementation may have some health promoting benefits. We evaluated the effects of green juice (Angelica keiskei) consumption on parameters of lipid profiles and plasma antioxidant status in healthy male smokers. Fifty-four smokers were supplemented with 300 ml of green juice for 6 weeks while maintaining their normal diet. Blood samples were collected on week 0 and week 6 in order to evaluate plasma lipid profiles (total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol) , plasma antioxidant vitamin levels (ascorbic acid, $\alpha$ -tocopherol, ${\gamma}$ -tocopherol, $\alpha$ -carotene, $\beta$ -carotene, cryptoxanthin and lycopene) , the degree of LDL oxidation and GOT, GPT levels for liver function. Plasma ascorbic acid level remained at the same level. However, $\alpha$ -tocopherol and ${\gamma}$ -tocopherol normalized by total cholesterol (p <0.05) and $\beta$ -carotene (p <0.001) level were all significantly increased after green juice supplementation. Plasma cholesterol was reduced for 12%, LDL-cholesterol was reduced for 9.3% after green juice consumption, while plasma triglyceride and HDL-cholesterol was not changed. Oxidized LDL assessed by conjugated diene (CD) , was decreased (p < 0.0001) after green juice consumption. These results further support a role for green juice supplementation in the improvement of lipid status, prevention of lipid peroxidation, and thereby reducing risk factors of numerous diseases associated with elevated oxidative stress in smokers.

  • The relationship between exercise intensity, oxidative stress and antioxidant status has been studied in sixteen trained male athletes aged 20-25years. Subjects performed 30-40minutes of treadmill running at 65% of VO2 max(high intensity exercise). Blood samples were taken before and immediately after two exercise bouts for measurement of blood antioxidants, indices of lipid peroxidation and susceptibility of crythrocyte to peroxidation. Plasma concentrations of cholesterol(7.3%), vitamin C(7.5%) and uric acid(2.1%) were elevated a little after exercise at 65% of VO2 max(13.7%)were significantly high than before exercise(p<0.05). However, these exercise-induced changes could be partly due to significant decreases in plasma volume which occurred after both exercise bouts(p<0.05). Plasma volume decreased 5.85$\pm$2.06% and 11.25$\pm$2.87% with exercise at 65% and 85% of VO2 max, respectively. The erythrocyte susceptibility to peroxidation after exercise at 65% of VO2 max was unchanged compared with the value before exercise, whereas after exercise at 85% of VO2 max, it was significantly higher than after exercise at 65% and 85% of VO2 max as well as before exercise(p<0.05). A significant increase at 85% of VO2 max, it was significantly high than after exercise at 85% of VO2 max (29.10$\pm$4.76ug/g Hb)when compared with the level before exercise (24.61$\pm$3.45ug/g Hb)(p<0.05). The results suggest that exercise-induced changes in plasma levels of lipid peroxide and antioxidant need to be evaluated, taking the shift in plasma volume into consideration. Also, exercise at high intensity corresponding to 85% of VO2 max alters the erythrocyte antioxidant status in relation to exercise-induced of oxidative stress.

  • This study was conducted to investigate the effects of shellfish on lipid metabolism in rats fed high fat supplements. Male sprague-dawley rats weighting approximately 165g were fed a basal diet, a high fat diet, or a high fat diet plus shellfish for 4 weeks. The shellfishes on the were oyster, hard-shelled mussel, little neck clam, and march clam. Alfter 4 weeks high fat diet, supplementation of 20% lard significantly increased plasma. GOT, GPT, ${\gamma}$-GTP , and liver triglyceride (TG). Plasma GOT, GPT, ${\gamma}$-GTP , triglyceride, and total cholestrerol levels were significantly lower in shellfish groups than in basal and high-fat groups regardless of high-fat supplementation (p<0.05). The total lipid and cholesterol content in liver showed similar results(p<0.05). There were no differences in glucose, HDL-cholesterol in plasma and total cholesterol and total lipid in liver between basal and high-fat supplemented diets. Liong chain fatty acids, specific components of shellfishes group, were exclusively higher than in basal and high-fat diets, and were most well-reflected in liver and plasma. From the above results, the hypolipidemic effects of shellfish were detected in the process of inducing hyperlipidemia by high-fat supplement.

  • This study was performed to investigate nutritional intake, the dietary behaviors and plasma lipid profile between smokers and non-smokers of college male students in the Gyeonggi Area. Dietary behaviors and attitude toward smoking were investigated by questionnaires. The result obtained were as follows: There was no significant difference in anthropometric measurements between smokers and nonsmokers. There was no significant difference in dietary behaviors. However, smokers tended to eat more snacks and desserts than nonsmokers. In plasma lipid levels, smokers had higher levels of plasma triglyceride, LDL-cholesterol, VLDL-cholesterol and total cholesterol than that of non-smokers(p<0.05). HDL-cholesterol level of smokers was a lower than that of non-smokers although the difference was not significant. AI(Atherogenic Index), Total /HDL cholesterol ratio and LDL/HDL cholesterol ratio of smokers were significantly higher than that of non-smokers(p<0.01). BMI and SBP showed positive correlation with triglyceride(p<0.01) and VLDL-cholesterol(p<0.01). DBP showed positive correlation with triglyceride(p<0.001) and VLDL-cholesterol(p<0.01).

  • This work was conducted to investigate dietary supplementation of oyster mushroom fruiting bodies on biochemical and histological changes in hyper and normocholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Feeding a diet containing a 5% powder of Pleurotus ostreatus fruiting bodies to hypercholesterolemic rats reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and LDL/high-density lipoprotein ratio by 30.18, 52.75, 59.62, 34.15, 23.89, and 50%, respectively. Feeding oyster mushrooms also significantly reduced body weight in hypercholesterolemic rats. However, it had no adverse effects on plasma albumin, total bilirubin, direct bilirubin, creatinin, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, or enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that P. ostreatus significantly reduced plasma ${\beta}$ and pre-${\beta}$-lipoprotein but increased ${\alpha}$-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red O staining revealed normal findings for mushroom-fed hypercholesterolemic rats. These results suggest that a 5% P. ostreatus diet supplement provided health benefits by acting on the atherogenic lipid profile in hypercholesterolemic rats.
