  • This study was designed to investigate the effect of age on the lipid metabolism in the rats fed different diets. In experiment A male Wistar rats of 5 weeks of age and of 32 weeks of age were divided into low fat diet groups and high fat-cholesterol groups. The rats were sacrificed 1 week, 2 weeks and 4 weeks after experiment begins. Also after 4 weeks. the rats in low and high fat diet groups were tube-fed 500mg of choelsterol and were sacrified 3 days later. In experiment b, male Wistar rats of 4 weeks of age and of 6 months of age were divided into 2 groups of butter and cron oil groups. And then eachgroup were divided into 2 subgroups ; meal feeding and nibbling groups . Each diet was fed for 4 weeks. In experiment A, age of the rats and experimental diets did not affect the serum cholesterol and triglycerides concentrations were higher in rats fed high fat cholesterol diet than in those fed low-fat or high -fat diets, but age of the animals had no effect on liver lipid content. The weight and cholesterol content of epidymal fat pad, however were higher in adult rats than in young ones regardless of the diets fed. When the rats were challenged with 500mg cholesterol, the rates of increase in serum and hepatic cholesterol level were higher in adult rats compared to young rats regardless of the diets . On the other hand, the rate of increase of small intestinal cholesterol content was lower in adult rats than in young rats. In experiment B, serum cholesterol and triglyceride content were relatively higher in young rats than adult ones. Stored body lipid was higher in adult rats, as judged by epididymal fat pad weight and total carcass lipid. Meal frequency and the kinds of fat in the diet did not affect the serum choelstero concentration . The serum triglyceride levels. however, was higher in butter fed rats thancron oil fed ones. The cholesterol content of live rand epididymal fat pad was lower in butter fed groups than corn oil groups for both young and adult rats, but there was no difference in liver triglycerides livel.

  • This study was undertaken to evaluate the effect of 4 weeks of $\alpha$-tocopherol(800 I.U./d) supplementation on oxidant stress of eleven female aerobic -majoring students during rest and exercise. Changes in the activity of the antioxidant enzyme glutathione peroxidase were also studied. Serum $\alpha$-tocopherol concentration was significantly increased with vitamin E supplementation(710.1$\pm$113.8$\mu\textrm{g}$/dl vs. 1,485,8$\pm$105.2$\mu\textrm{g}$/dl). In addition, serum MDA concentration, an index of lipid peroxidation, significantly decreased after vitamin E supplementation. However, MDA values after exercise increased to pre-supplementation levels. Serum glutathione peroxidase activity significantly increased with vitamin E supplementation. The enzyme activity showed a trend toward decrease after exercise. Serum cholesterol values were not significantly affected by vitamin E supplementation. However, serum triglycerides significantly increased after supplementation against oxidative stress during resting periods. These supplements appraently work by decreasing lipid peroxidation and increasing glutathione peroxidase activity. However, vitamin E supplementation did not prevent exercise-induced increases in lipid peroxidation.

  • Lipid consumption in early life has been implicated with arteriosclerosis in later life. It has been also claimed that lipid contents of serum in early life would reflect coronary atherosclerosis in later life. Present study has been undertaken to look for serum lipid contents of mother and newborn simultaneously to determine the difference of various lipid classes. Lipids were extracted by Folch method. Total lipid was determined gravimetrically; cholesterol by Zak's method, phospholipids by Fiske-Subba-Row's method, and triglycerides by Sugiura's method. Fatty acids were analysed by gas liguid chromatography. Values of the total lipids of mother was significantly higher than those of newborn. HDI-cholesterol/total cholesterol ratio of newborn's was higher than mother's. The amount of saturated fatty acids in the serum cholesteryl ester of newborn was significantly higher than mother's.

  • The objective of this study were to investigate the effects of Se and Vit. E administration on blood chemical values and Vit. E concentrations of serum in calves born from Hanwoo dams injected Se and Vit. E at late pregnancying periods. The effects of Se and Vit. E administration of blood chemical values in calves born from Hanwoo dams injected Se and Vit. E at the last month of pregnancying periods were examined. In albumin concentration of blood, the Vit. E 2000IU group were slightly higher than other groups and the cholesterol concentrations were also higher in Vit. E 15001u group than other groups. But, another components examined of blood chemical values were not significantly different in all experimental groups. The blood chemical values in calves born from Hanwoo dams administrated Se and Vit. E at two months before parturition were examined. However, there were not significantly different in all experimental groups in concentrations of albumin, cholesterol, BUN, creatinine, glucose, inorganic phosphorous, calcium, total protein and triglycerides. The concentrations of serum Vit. E in calves born from Hanwoo dams administrated Se and Vit. E at 30 and 15 days before parturition were examined. The concentrations of Vit. E in serum were higher in treatment groups than in control group(P>0.05). The concentrations of serum Vit. E in calves born from Hanwoo dams administrated Se and Vit. E at 60 days before parturition were examined, the concentrations of Vit. E in serum were slightly higher in groups administrated than in control group(P>0.05), but there were not significantly difference in all experimental groups.

  • Purpose: Preterm infants on parenteral nutrition are at a relatively high risk for hypertriglyceridemia because they have immature lipoprotein lipase activity. The purpose of this study was to analyze the clinical factors affecting lipid metabolism in preterm infants receiving parenteral nutrition and to evaluate the influence of intravenous heparin on serum triglycerides to determine the adequate heparin dose to prevent hypertriglyceridemia in preterm infants. Methods: A single-center retrospective review was conducted among preterm infants receiving parenteral nutrition between January 2006 and February 2011. In 75 patients, 110 determinations were performed within 28 days postnatal age. Demographic and clinical data, including laboratory parameters, the dose and the duration of lipid administration, and the amount of intravenous heparin, were analyzed. Results: Serum triglycerides were higher in the small for gestational age (SGA) infants than in the appropriate for gestational age infants ($185.5{\pm}134.9$ mg/dL vs. $126.9{\pm}101.9$ mg/dL, p=0.019). Birth weight, gestational age, and body weight were negatively correlated with serum triglyceride level (r=-0.289, p=0.002; r=-0.208, p=0.029; r=-0.287, p=0.002, respectively). The serum triglyceride level was statistically lower in preterm infants receiving 1 U/mL of heparin than in those receiving 0.5 U/mL heparin or no heparin. Conclusion: Preterm infants receiving parenteral nutrition, particularly SGA and extremely low birth weight infants, tend to have hypertriglyceridemia. Thus, administration of 1 U/mL of heparin rather than 0.5 U/mL or none may be helpful to prevent hypertriglyceridemia in preterm infants.

  • Objectives : This study was performed to investigate the effects of Pinelliae rhizoma on blood serum lipids and skeletal muscle fatty acid metabolism of obese Zucker rats. Methods : Experimental groups were divided into normal Zucker rats (lean control; non-treated), obese Zucker rats (fat control; non-treated) and Pinelliae rhizoma oral feeding obese Zucker rats (fat control; treated) for 6 separate experiments. Pinelliae rhizoma was investigated for effects on total body weight, serum glucose content, total cholesterol and triglyceride content, free fatty acid content, PPARalpha, CS and beta-HAD. Results : 1. Triglycerides in blood serum showed a greater decrease in the Pinellia rhizoma oral feeding group than the overweight control group. 2. PPARa showed a significant increase in the Pinelliae rhizoma oral feeding group over the overweight control group in skeletal muscles of SOL and EDL: as for protein FABPc, the Pinelliae rhizomaoral feeding group saw a greater significant increase than the overweight control group in the skeletal muscles of SOL. 3. CS activity showed a greater increase for the Pinelliae rhizoma oral feeding group than the overweight control group in EDL Conclusions : As the experiment's results show, Pinelliae rhizoma effectively decreased the weight and triglycerides of the obese mouse, and somewhat affects the fat oxidation in the skeletal muscles.

  • We investigated the effect of high density lipoprotein from egg yolk (EYHDL) on serum, hepatic and fecal lipid and fatty acids (FAs) levels and on gene expression involved in FAs metabolism. Male KM mice were fed either normal diet (ND; n=20), high fat diet (HFD; n=20), or high fat diet containing EYHDL (EYHDL; 0.6 mg/g, every day by oral gavage, n=20) for 100 days. At the end of the experiment, the effects of treatments on biochemical parameters, FAs profiles and involved gene expression were analyzed. Our results revealed that EYHDL markedly suppressed the body weight gain, accumulation of abdominal fat tissues, serum concentrations of LDL-cholesterol (LDL-C) and triglycerides, hepatic triglycerides and cholesterol accumulation, while increased serum concentration of HDL-cholesterol (HDL-C). EYHDL intake also increased total cholesterol (TC) excretions compared with HFD group. Moreover, it alleviated the severity of fatty liver and improved glucose and insulin tolerance compared with HFD. More importantly, EYHDL partially normalized FAs profiles in serum, liver and fecaces and neutralized the HFD-induced upregulation of SREBP-1c, Acaca, Fasn, GPAT and Scd1. In conclusion, our findings indicate that EYHDL may have the potential to improve metabolic disturbances that occur in HFD mice and can be considered as an appropriate dietary recommendation for the treatment of metabolic syndrome (MetS).

  • It has been reported that the increased uric acid level is associated with metabolic syndrome risk factors in both male and female. However, there has not been enough studies to investigate gender differences of this association in Korea. To evaluate relation between serum uric acids and metabolic syndrome markers, anthropometric and biochemical analyses data was obtained from National Health Examination 2005 and 5,523 (M=3,097; F=2,426) data was analyzed. Results by quartile of serum uric acid levels in females showed that increased serum uric acid level was associated with elevated levels of total-. LDL-cholesterol, and triglycerides, whereas association between serum uric acid and total cholesterol levels was not observed in male subjects. In both female and male, higher quartile of serum uric acid level were linked with lower levels of HDL-cholesterol. In regression analysis, association of serum uric acid levels with fasting glucose levels was significant in female subjects only. In conclusion, higher serum uric acid levels were associated with metabolic syndrome indices, however gender differences were existed for total cholesterol.

  • Objectives: Dyslipidemia in diabetes mellitus is a significant risk factor for the development of cardiovascular complications. The aim of this study was to evaluate the effect of the ethyl-acetate fraction of an ethanolic extract from Streospermum suaveolens on lipid metabolism in streptozotocin (STZ)-induced diabetic rats. Methods: Diabetes was induced by intraperitonial injection of STZ (50 mg/kg). Diabetic rats were treated with an ethyl-acetate fraction orally at doses of 200 and 400 mg/kg daily for 14 days. On the $15^{th}$ day, serum lipid profiles, such as total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), were estimated in experimental rats. The atherogenic (AI) and the coronary risk (CRI) indices were also evaluated. Results: The ethyl-acetate fraction at doses of 200 and 400 mg/kg significantly (P < 0.001) and dose-dependently reduced serum cholesterol, triglycerides and LDL, but increased HDL towards near normal levels as compared to diabetic control rats. The fraction also significantly (P < 0.001) lowered the atherogenic index (AI) and coronary risk index (CAI) in a dose-dependent manner. Conclusion: The present study demonstrated that the ethyl-acetate fraction of Stereospermum suaveolens exhibits a potent antihyperlipidemic activity in hyperglycemic rats and suggests that the plant may have therapeutic value in treating the diabetic complication of hyperlipidemia.

  • Oxidant/antioxidant balance has been suggested as an important factor for initiation and progression of cancer. The objective of this study was to determine changes in the levels of malondialdehyde (MDA), nitric oxide (NO), total cholesterol, triglycerides, LDL-cholesterol, HDL-cholesterol, total antioxidant capacity (TAC), glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) activities in serum samples of breast cancer patients (n=30) and healthy subjects (n=100). MDA and NO levels were found to be increased in breast cancer patients compared to the healthy subject group (p<0.05). Total cholesterol and triglycerides were elevated; and HDL-cholesterol level was found to be decreased in the cancer patients as compared to the healthy subjects (p<0.05). Compared to the healthy group, both serum TAC levels (p<0.001) and activity of SOD and GSH-Px (p=0.05) were found to be decreased in the breast cancer patients as compared to the healthy controls. Considering the data presented in this study, we suggest that free radicals induce lipid eroxidation and peroxidation of unsaturated fatty acid with decreased activity of enzymatic antioxidants in breast cancer.
