  • Effects of a change in dietary Ca content and an alteration in dietary lipid type on lipid metabolism have been investigated in male Sprague-Dawley rats. The results obtained were summarized as follows ; 1) There was no comparable changes in food consumption and body weight gain among all 9 groups. 2) Serum total lipids and cholesterol were lowest when high Ca-corn all diet was fed, and highest when low Ca-butter diet was fed. 3) The contents of total lipids and cholesterol per g liver and total liver showed no consistent tendency with the dietary treatment. 4) Addition of Ca to the diet caused the significant increase in the dry fecal matter and fecal Ca. And fecal total lipids and fecal cholesterol were much greater if the high-Ca diet was fed than if control and low-Ca diet were fed. It is concluded that Ca and polyunsaturated acids have tendency of hypocholesterolemic effect.

  • The effects of hwangryun(Coptidis Rhizoma) on lowering lipid and oxidative stress in the induced obesity rat was observed. The concentration of plasma triglyceride in hwangryun treatment groups showed the low values compared to the control group, and as the increased hwangryun, the concentration of triglyceride decreased. The concentration of plasma total cholesterol decreased in all hwangryun treatment groups. However the concentration of plasma HDL-cholesterol and LDL-cholesterol showed no significantly difference in all the treatment groups. Thiobarbituric acid reactive substance(TBARS) concentration in plasma and liver showed low values in all hwangryun treatment groups compared to the control group. Glutathione peroxidase(GSH-Px) and superoxide dismutase(SOD) activities showed no significantly difference in all the treatment groups. However catalase(CAT) activity showed a tendence to increase in hwangryun groups, and in 200mg/kg hwangryun treatment group showed significantly a high value than the control group. Summarizing the results above, hwangryun has the functional materials that lowering lipid and works with oxidative stress.

  • Dyslipidemia in nephrotic syndrome (NS) is often characterized by marked increases in the levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and other lipoproteins, such as very low-density lipoprotein, intermediate-density lipoprotein, and lipoprotein(a). It has been suggested that impaired catabolism of lipoproteins and cholesterol is mainly due to decreased lipoprotein lipase and hepatic lipase activity, and increased biosynthesis of lipoproteins in the liver. The management strategies for dyslipidemia in patients with NS consist of lifestyle modification, lipid-lowering agents represented by statins, second-line agents such as fibrates and bile acid sequestrants, and lipid apheresis. Compared with dyslipidemia in adult NS patients, whose risks of atherosclerotic disease and progressive renal injury are considered high, clinical data on dyslipidemia in pediatric NS patients are limited. Therefore, it is necessary to pay more attention to the evaluation and management of dyslipidemia in pediatric patients with NS in clinical practice.

  • This study was conducted to investigate the relationship between body fat content and serum lipids in college students. A total of 61 (15 males and 46 females) students of W university in Iksan, between June 2015 and July 2015, were enrolled for analysis. The relationship of serum lipid with BMI, and body fat percent measured by impedance fat meter (InBody 520) was analyzed. The study population was divided into three groups according to the InBody 520's guideline. Group I accounted for 26.7% of men and 10.9% of women. Weight and BMI were significantly different among the three groups in men and women (p<0.05); whereas height was not. In men, serum total cholesterol, triglyceride, low density lipoprotein cholesterol, and hemoglobin were significantly different between the three groups (p<0.05). Conversely, in women, serum total cholesterol, low density lipoprotein cholesterol, and alanine transferase were significantly different between the three groups (p<0.05). However, there were no differences in other variables between the three groups. BMI was significantly different among three groups in both men and women (p<0.05). In men and women, body fat percent was correlated with BMI, weight, total cholesterol, and low density lipoprotein cholesterol. Multiple regression analysis on total cholesterol indicates that body fat percent, BMI, and hemoglobin were not significantly independent variables in men and women. This study showed that body fat percent was significantly associated with other obesity markers and serum lipids.

  • Lipid and cholesterol were extracted from beef and pork by the supercritical carbon dioxide $(SC-CO_2)$ for the manufacturing of low-lipid and low-cholesterol sausage. The ranges of extraction temperature and pressure were from 35 to $55^{\circ}C$ and from 103 to 375 bar, respectively. $SC-CO_2$ extraction yield of beef lipid increased as extraction pressure increased and/or extraction temperature decreased, while extraction temperature was more influential on the cholesterol extraction than pressure condition. When lipid and cholesterol of freeze-dried beef with varied moisture contents were extracted, their solubilities increased as the moisture content reduced. The extraction of lipid and cholesterol from pork was shown the same tendency as the beef. The chunk type of beef shape was more suitable for the lipid and cholesterol extraction than the powder type of beef. The color of meat after $SC-CO_2$ extraction was lighter than the raw freeze dried meat because of the extraction of color pigments. After $SC-CO_2$ extraction, beef and pork were rehydrated and mixed with raw beef and pork containing lipid and cholesterol. Their mixing ratio up to 50 : 50 did not affect physical properties of the sausage compared with the control sausage.

  • Objectives This study is to investigate the effects and mechanisms of Imyo-san (IMS) on the obese mice model induced by high-fat diet. Methods Antioxidative capacity was measured by in vitro method. C57BL/6 mice were randomly assigned into 5 groups (n=7). Normal group was fed general diet (Normal). The other 4 groups were fed high fat diet (HFD) with water (Control), with Garcinia gummi-gutta (GG, Garcinia gummi-gutta 200 mg/kg), with low-dose IMS (IMSL, Imyo-san 0.54 g/kg) and with high-dose IMS (IMSH, Imyo-san 1.08 g/kg). Results IMS showed high radical scavenging activity. After 6 week experiment, body weight, food intake, food efficiency ratio (FER), epididymal fat and liver weight, triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, very low density lipoprotein (VLDL) cholesterol, sterol regulatory element-binding protein-1 (SREBP-1), phospho-acetyl-CoA carboxylase (p-ACC), fatty acid synthase (FAS), stearoyl-CoA desaturase-1 (SCD-1), SREBP-2, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), phospho-liver kinase B1 (p-LKB1), phospho-AMP-activated protein kinase (p-AMPK), peroxisome proliferator-activated receptor 𝛼 (PPAR𝛼), peroxisome proliferator-activated receptor 𝛾 coactivator-1𝛼 (PGC-1𝛼), uncoupling protein-2 (UCP-2), carnitine palmitoyltransferase 1A (CPT-1A), and histology of liver and epididymal fat were measured and analysed. Body weight gain, FER, liver and epididymal fat weight of IMS groups were significantly decreased. There were significant improvements in blood lipids with less TG, TC, LDL-cholesterol, VLDL-cholesterol and more HDL-cholesterol. Proteins associated with lipid synthesis (SREBP-1, p-ACC, FAS, SCD-1) and cholesterol (SREBP-2, HMGCR) was improved. Factors regulating lipid synthesis and lipid catabolism (p-LKBI, p-AMPK, PPARα, PGC-1α, UCP-2, CPT-1A) were increased. In histological examinations, IMS group had smaller fat droplets than control group. All results increased depending on concentration. Conclusions It can be suggested that IMS has anti-obesity effects with improving lipid metabolism.

  • This study examined the antioxidant activity and lipid composition of rats fed a high fat-high cholesterol diet containing Salvia plebeia water extract. Three levels (50 mg/kg, 200 mg/kg, 500 mg/kg) of Salvia plebeia water extract were administered to seven weeks old male Sprague Dawley rats for four weeks. The activity of glutathione peroxidase in serum was high in all groups that received the Salvia plebeia water extract (p<0.05). The glutathione reductase activity was high (p<0.05) in groups that received 50 mg/kg and 500 mg/kg of Salvia plebeia water extract. When rats received Salvia plebeia water extract, the content of MDA (malondialdehyde) in the serum and liver was low in all groups. In addition, the serum total lipid, triglyceride, total cholesterol and LDL-cholesterol contents decreased significantly (p<0.05). Total cholesterol and triglyceride levels in the liver were significantly lower in the group that received the Salvia plebeia water extract than in the control group (p<0.05). Salvia plebeia water extract improves lipid metabolism and it almost meets with the increase of antioxidant activity and peroxide formation reduction. Based on these results, supplemented of a high fat-hypercholesterol diet with Salvia plebeia can increase antioxidant activity and depress peroxide formation in serum, as well as liver cholesterol and triglycerides.

  • The study examines the effects of the Cnidium officinale Makino water extract on hyperlipidemia. For this, three levels (low, moderate, and high) of the Cnidium officinale Makino water extract were supplemented to six-week-old male sprague Dawley rats for five weeks. According to the results, serum total lipid, triglyceride, total cholesterol, and LDL cholesterol levels showed significant decreases (p<0.05) in the group with the Cnidium officinale Makino water extract. The serum total lipid level decreased by 8~22%; the triglyceride level, by 13~25%; the total cholesterol level, by 6~23%; and the LDL cholesterol level, by 14~25%. Total cholesterol and triglyceride levels in the liver were significantly lower in the group with the Cnidium officinale Makino water extract than in the control group (p<0.05), and fecal total cholesterol and triglyceride levels were significantly higher in the group with the Cnidium officinalle Makino water extract. These results suggest that the Cnidium officinale Makino water extract in the hypercholesterol diet may reduce hyperlipidemia, a major cause of cardiovascular disease, by reducing serum cholesterol and triglyceride level in the liver through the facilitation of their excretion by feces.

  • Moderate alcohol consumption has been known to be associated with reduced risk for coronary heart disease (CHD). We assessed the association between alcohol consumption and CHD-related risk factors [hypertension, diabetes mellitus (DM) , high total cholesterol, high triglyceride (TG), low HDL-cholesterol (HDL-C), and high LDL-cholesterol (LDL-C)] in Korean. After excluding those with extreme intake values, the number of final subjects included in the analysis was 4,662 Korean adults aged over 20 years (1,961 men, 2,701 women) who participate in the 2005 Korean National Health and Nutrition Examination Survey. The subjects were divided into four or five groups; none-alcohol consumption group, moderate alcohol consumption group (<15 or 15.0-29.9 g/d), heavy alcohol consumption group (30-69.9 g/d or ${\geq}$ 70 g/d in men, ${\geq}$ 30 g/d in women). Odds ratios (ORs) were estimated from logistic regression adjusting for potential covariates. Alcohol consumption was inversely associated with low HDL-C in both men and women. However, heavy alcohol intake (${\geq}$ 70 g/d) significantly increased risk for hypertension, DM, and hypertriglyceridemia in men. The frequency of alcohol intake was also associated with CHD risk. The risk for low HDLC was decreased with alcohol consumption (${\geq}$ 1 times/wk), but frequent alcohol intake (${\geq}$ 4 times/wk) increased the risk for hypertension. This study revealed that moderate alcohol consumption has protective effect on CHD-related risk factors in Korean population.

  • In other to investigate the hypolipidemic effect of dry edible leaves on serum lipids, four kinds of powdered leaves(persimmom, mulberry, perilla, and soy bean) were added to experimental diets at the levels of 5%(w/w). The diets were fed to 30 male Sprague-Dawley rats, aged 4 weeks and weighing 60$\pm$5g, for 3 weeks. Food intake was the largest in Group 1(control), with 5% of cellulose powder, while food efficiency was the highest in Group 2(persimmon). Total cholesterol level in serum was lower in Group 5(soybean) and Group 4(perilla) than the other groups. In comparison with Group 1, HDL-cholesterol level was very high in Group 4 and atherogenic index was low in Groups 4 and 5. Free cholesterol level was the highest in Group 2, and was the lowest in Group 1. Both LDL and LDL-cholesterol levels were the lowest in Group 1, while they were very high in Groups 2 and 3(mulberry). Triglyceride level was the lowest in Group 4, and the highest in Group 1. Except Group 3, all groups had lower phospholipid level than Group 1. Compared with Group 1, calcium level in serum was low in Groups 3, 4 and 5, magenesium level was low in Groups 2, 3 and 5, phosphate level was high in Group 4, and iron level was exceptionally low in Groups 4 and 5. In conclusion, Group 4(perilla) and Group 5 (soybean) showed a favorable effect in atherogenic index and serum levels of various lipids.
