  • This study was performed to investigate the cholesterol-lowering effect of liquid extract from Leonurus sibiricus Linne (LS). SD rats were fed atherogenic diet for 6 weeks. During the experimental period, LS liquid extract (3 g/kg and 6 g/kg) was orally given to the rats. The liver weight and levels of total cholesterol, LDL-cholesterol, and triglycerides in serum were significantly increased in rats fed with atherogenic diets. Oral treatment of LS liquid extract to the rats fed atherogenic diet significantly reduced the liver weights and significantly decreased the levels of total cholesterol, LDL-cholesterol, and triglycerides. The level of serum HDL-cholesterol was significantly increased at a high dose group compared with rats fed normal diet chow. These results indicate that LS liquid extract has the potential to restore altered lipid profiles induced by cholesterol rich diets and prevent the development of atheroclerosis.

  • Antihyperlipidemic effect of taurine was investigated in the hyperlipidemic rats induced by feeding a diet supplemented with cholesterol (1.5% in diet), vitamin $D_2$(1.25 million IU/kg of diet) and cholic acid (0.5% in diet). The rats were fed the diet containing 1% and 3% of taurine for 8 weeks. The contents of the cholesterol and triglycerides in the serum and liver of the hyperlipidemic rats were increased as compared with those of the control group. Feeding taurine resulted in decreases in total cholesterol and triglyceride levels. The HDL-cholesterol level in serum was decreased in the hyperlipidemic rats, but by administration of taurine its level was increased. In the aorta of the animals, total cholesterol and triglycerides contents were reduced significantly by treatment with taurine. The contents of calcium in the heart of hyperlipidemic rats were greatly increased as compared with those of the control group. Treatment of taurine produced significant decreases in calcium contents in the heart muscle of the animals. These results showed that the hyperlipidemic states in this model of rats were reversed by treatment of taurine.

  • In this study, we have attempted to understand the effects of taurine on serum and liver concentrations of cholesterol and triglycerides in broiler chickens and mice in the post-absorptive state, and on in vitro protein synthesis in the livers of broiler chickens and laying hens, as well as the effects of taurine on in vivo protein synthesis in the liver of mice. The experimental animals were subjected to 24 h of starvation in order to perpetuate a post-absorptive state. Serum concentrations of high density lipoprotein cholesterol and triglycerides were significantly (p<0.05) higher in the taurine groups than in the controls in both the broilers and the mice. However, taurine resulted in a significant (p<0.05) reduction in liver concentrations of total cholesterol and triglycerides, relative to what was seen in the control groups of both animals. Taurine stimulated the in vitro synthesis of 57-kDa, 40-kDa and 23-kDa proteins in the liver of broilers, but inhibited the in vitro synthesis of 54-kDa, 37-kDa and 24-kDa proteins. Taurine in the liver of laying hens exerted effects on in vitro protein synthesis, with the exception of the 26-kDa protein which was not detected in broiler liver, but was inhibited by taurine in the liver of laying hens. Unlike the findings regarding in vitro protein synthesis in the liver of broilers or laying hens, taurine appeared to stimulate the synthesis of only two proteins, a 47-kDa and a 40-kDa protein, in the liver of mice. Overall, theses findings indicate that taurine treatment results in a reduction in cholesterol and triglyceride concentrations, and also affects protein synthesis in the livers of broilers, laying hens, and mice.

  • Dietary karaya saponin and Rhodobacter capsulatus (R. capsulatus) are known to have hypocholesterolemic actions, as reported in our previous studies. This study examined possible synergistic hypocholesterolemic effects of karaya saponin and R. capsulatus in broilers. A total of 150 broilers were allocated into 10 treatments: control, saponin 25 mg, saponin 50 mg, saponin 75 mg, saponin 25 mg+R. capsulatus 0.2 g, saponin 25 mg+R. capsulatus 0.4 g, saponin 50 mg+R. capsulatus 0.2 g, saponin 50 mg+R. capsulatus 0.4 g, saponin 75 mg+R. capsulatus 0.2 g and saponin 75 mg+R. capsulatus 0.4 g. Feed intake and feed efficiency were improved when karaya saponin and R. capsulatus were synergistically supplemented in the diet. Combinations of karaya saponin, especially supplementation of karaya saponin 50 mg+R. capsulatus 0.4 g were shown to have potential hypolipidemic actions in breast and thigh muscle cholesterol and triglycerides, serum cholesterol, low density lipoprotein-cholesterol and triglycerides, as well as improved high density lipoprotein (HDL)-cholesterol (p<0.05). Compared to the control, almost all the treatments significantly increased serum, liver and fecal concentrations of bile acids (p<0.05). Supplementation of both karaya saponin (75 mg) and saponin 50 mg+R. capsulatus 0.4 g reduced palmitic acid (C16:0) and stearic acid (C18:0) in a similar fashion (p<0.05). The ratios of PUFA:SFA or PUFA+MUFA:SFA in the thigh and breast muscle of broilers were greater in karaya saponin and R. capsulatus supplemented groups than in the control group. Thus, our study concluded that supplementation of karaya saponin synergistically with R. capsulatus in the diet of broilers is an effective way to obtain low-cholesterol, low-triglyceride and high HDL-cholesterol enriched poultry meat with a unique fatty acid balance.

  • The purpose of this study was no investigate serum lipid levels of primary school children and to estimate their intakes of total fat and fatty acids. Subjects fasting blood samples were obtained and analyzed for serum triglycerides(TG), total cholesterol(Chol) and high density lipoprotein-cholesterol (HDL-Chol). Low density lipoprotein cholesterol (LDL-Chol), LDL-Chol/HDL-Chol ratio(LPH), and atherogenic index(AI) were calculated,. Dietary intake of nutrients was assessed by means of a 24-hour recall method using food models and other measuring tools . The serum levels of TG, Chol and LDL-Chol in girls were higher than those in boys, but the serum HDL-Chol level of girls was lower than that of boys. As the degree of obesity increased, the serum TG level of girls was lower than that of boys. As the degree of oesity increased , the serum TG level of girls increased. The serum LDL-Chol level was higher in obese boys than in normal ones. Percentage s of subjects at risk of cardiovascular disease based on corresponding criteria of TG, Chol,HDL-CHol and LDL-Chol were 25.9%, 7.6%, 20.7% and 10.1%, respectively. The serum TG level of children provided with the national school lunch program(NSLP) was lower than that of children without NLSP. The total fat intake of boys was higher than that of girls, but calorie-adjusted fat intake became similar between the two groups. Intakes of polyunsaturated fatty acids(PUFA), monounsaturated fatty acids(MUFA) and saturated fatty acids(SFA) were 13.3$\pm$9.5g, 16.1$\pm$9.3g and 21.4$\pm$14.2g in boys, respecitively , and 12.6$\pm$11.3g, 15.3$\pm$9.7g and 19.9$\pm$13.1g in girls, respectively . The ratios of polyunsaturated /monoun-saturated /saturated /saturated fatty acids(P/M/S) in boys and girls were 0.7/0.8/1.0 and 0.8/0.8/1.0 respectively. The ratios of $\omega$6/$\omega$3 fatty acids in boys and girls were found to be 12.1 /1.0 and 8.6/1.0 , respectively. These results indicated the urgent need of nutritional education in primary schools to prevent further increase in childhood obesity and hyperlipidemia . Therefore, this study will contribute to the establishment of dietary guidelines and health recommendation for school children.

  • This study investigated the effects of Wolbiga-banha-tang (WBBT) on high fat diet-induced rats. We divided the rats into 4 groups: normal (fed a general-fat diet), control (fed a high-fat diet and no treatment), $WBBT{\times}1$ (fed a high-fat diet and 250 mg/kg of Wolbiga-banha-tang extracts), and $WBBT{\times}2$ (fed a high-fat diet and 500 mg/kg of Wolbiga-banha-tang extracts). We measured the body weight, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, free fatty acids, total lipids, AST, ALT, and CBC in the serum of the obese rats for 7 weeks. There was a significant decrease in the control group, $WBBT{\times}1$, and $WBBT{\times}2$ in triglycerides and free fatty acids. The results suggest that WBBT is effective for lowering triglycerides and free fatty acids. Therefore, WBBT may be applied to the treatment of lipid metabolism in obesity and further clinical studies are needed.

  • It was studied whether fenofibrate alone or combinational treatments of fenofibrate and 17β-estradiol regulates serum lipid levels, and whether the effects of fenofibrate on serum lipid metabolism are affected by co-administration of 17β-estradiol in low-fat diet-fed ovariectomized female mice. Compared with low-fat diet-fed controls, mice treated with fenofibrate alone and mice treated with fenofibrate and 17β-estradiol didn't decrease body weight at 8 weeks. Fenofibrate alone or combinational treatments of fenofibrate and 17β-estradiol did not regulate serum levels of total cholesterol and HDL-cholesterol. Fenofibrate decreased plasma levels of LDL-cholesterol and triglycerides compared with controls. The combinational treatments of fenofibrate and 17β-estradiol showed more beneficial effects on triglycerides than fenofibrate alone. Therefore, the present study found that serum triglycerides reduced by fenofibtae treatment alone could be more improved by combinational treatments of fenofibrate and 17β-estradiol in low-fat diet-fed ovariectomized female mice.

  • This study was attempted to observe leisure time physical activity pattern and its relationship to coronary risk factors (BMI, systolic blood pressure, diastolic blood pressure, serum total cholesterol, triglycerides, fasting blood sugar). Subjects participated in this study were 277 adult male workers of an industry in Kyungpook province, Korea. Energy expenditure were measured using modified Physical Activity History questionnaire of CARDIA study by interviewing. Serum total cholesterol, triglycerides and blood sugar level were tested with 5 ml fasting blood and height, weight and blood pressure were masured. Data on smoking and drinking habits and others were obtained. Geometric mean of leisure time physical energy expenditure were estimated as 212.80 kcal per week for study subjects and only 22.4% of them expended 2,000 kcal or more per week in leisure time physical activity. Taking walks or hikes and jogging or running were more frequent leisure time physical activities in study subjects. Statistically significant mean differences in total weekly leisure time physical activity for all coronary risk factors were not found among three groups. Because energy expenditure of leisure time was generally low in this subjects and most of them were healthy men, we did not found that leisure time physical activity was significantly associated with coronary risk factors.

  • The aim of the study was to determine whether vitamin E supplementation in three experimental model rats with impaired glucse tolerance could change serum insulin concentration and lipid distribution. The three groups were adult(AS) and neonatal (NS) streptozotocin-induced groups, and a high sucrose diet(HS) group. Each group was divided into control and vitamin E supplementatino groups at the age of 9 weeks. The level of vitamin E supplementation was 5g/kg diet. Blood and organ samples were taken at 5 and 10 weeks and were examined for changes in the level of serum insulin, glucose, lipids, liver lipids, and oxidative status. Vitamin E supplementation significantly reduced serum insulin in the HS group and caused the significant beneficial changes in serum lipids and triglycerides in As grouop at 10 weeks . In all groups, serum vitamin E was increased and malondialdehyde(MDA) in serumand liver were decreased significantly by vitamin E supplementation. The results suggest that vitamin E supplementation improves lipid distribution in adult streptozotocin-induced rats and serum insulin concentration in high sucrose diet-induced rats. Vitamin E might prevent on reduce oxidative injury in all experimental model rats with impaired glucose tolerance.
