Two hundred and sixteen Institut de S$\acute{e}$lection Animale (ISA) brown layers (40 wks of age) were studied for 6 wks to examine the effect of microalgae powder (MAP) on egg production, egg quality, blood lipid profile, and fatty acid concentration of egg yolk. Dietary treatments were as follows: i) CON (basal diet), ii) 0.5% MAP (CON+0.5% Schizochytrium powder), and iii) 1.0% MAP (CON+1.0% Schizochytrium powder). From 44 to 46 wks, egg production was higher in 1.0% MAP treatment than in control treatment (linear, p = 0.034); however, there was no difference on the egg production from 40 to 43 wks (p>0.05). Serum triglyceride and total cholesterol were significantly reduced in the groups fed with MAP, compared to those in groups fed with control diets (Quadratic, p = 0.034 and p = 0.039, respectively). Inclusion of 0.5% MAP in the diet of layers improved egg yolk color, compared with hens fed with basal diet at 46 wks (quadratic, p = 0.044). Eggshell thickness was linearly increased in MAP-fed treatments at 46th wk (p<0.05). Concentration of yolk docosahexaenoic acid (DHA; C22:6n-3) was increased in treatment groups fed with MAP (linear, p<0.05). The n-6 fatty acids, n-6/n-3 fatty acid, and unsaturated fatty acid/saturated fatty acid were decreased in treatment groups fed with MAP (linear, p<0.05). These results suggest that MAP improved the egg production and egg quality, and may affect serum lipid metabolites in the layers. In addition, MAP increases yolk DHA levels, and deceases n-6/n-3 fatty acid ratio.

Objective: This study was investigated the effects of dietary supplementation of Antrodia cinnamomea fermented product on modulation of antioxidation, anti-inflammation, and lipid metabolism in broilers. Methods: Functional compounds and in vitro antioxidant capacity were detected in wheat bran (WB) solid-state fermented by Antrodia cinnamomea for 16 days (FAC). In animal experiment, 400 d-old broiler chickens were allotted into 5 groups fed control diet, and control diet replaced with 5% WB, 10% WB, 5% FAC, and 10% FAC respectively. Growth performance, intestinal microflora, serum antioxidant enzymes and fatty acid profiles in pectoral superficial muscle were measured. Results: Pretreatment with hot water extracted fermented product significantly reduced chicken peripheral blood mononuclear cells death induced by lipopolysaccharide and 2,2'-Azobis(2-amidinopropane) dihydrochloride. Birds received 5% and 10% FAC had higher weight gain than WB groups. Cecal coliform and lactic acid bacteria were diminished and increased respectively while diet replaced with FAC. For FAC supplemented groups, superoxide dismutase (SOD) activity increased at 35 days only, with catalase elevated at 21 and 35 day. Regarding serum lipid parameters, 10% FAC replacement significantly reduced triglyceride and low-density lipoprotein level in chickens. For fatty acid composition in pectoral superficial muscle of 35-d-old chickens, 5% and 10% FAC inclusion had birds with significantly lower saturated fatty acids as compared with 10% WB group. Birds on the 5% FAC diet had a higher degree of unsaturation, followed by 10% FAC, control, 5% WB, and 10% WB. Conclusion: In conclusion, desirable intestinal microflora in chickens obtaining FAC may be attributed to the functional metabolites detected in final fermented product. Moreover, antioxidant effects observed in FAC were plausibly exerted in terms of improved antioxidant enzymes activities, increased unsaturated degree of fatty acids in chicken muscle and better weight gain in FAC inclusion groups, indicating that FAC possesses promising favorable mechanisms worthy to be developed.

Previously we have reported that black ginseng was produced by nine-time repeated steaming 5-year fresh ginsengs at 95${\circ}$C for 3hr in pottery apparatus and drying at 60${\circ}$C for 12${\sim}$36 hr and had an outstanding anticancer activity. This study was designed to examine the ability of black ginseng to suppress body weight gain appetite, and to investigate the effect of black ginseng on lipid profile in male rats fed normal diets. The extract of black ginseng was administered daily for 3 weeks, and the changes of body weight and food intake were measured. After administering the extracts for 3 weeks, the fat weight and serum lipid levels were also measured. Black ginseng persistently suppressed weigh gain and food intake was also reduced, but not significantly; The weight of both epididymal and abdominal fats was decreased In black ginseng-treated rats. Serum triglyceride level in rats administered with black ginseng was also significantly lowered. Therefore, these results reveal that the repeated administration of black ginseng causes a suppression of body weigh gain by decreasing triglyceride level in blood and body fat deposit.

Objective: To examine the effects of sodium intake on the correlations between the saltsensitive gene ${\alpha}$-adducin 1 (ADD1) and inflammatory cytokines in Korean childhood obesity. Methods: A total of 2,070 students aged 8-9 years old participated in this study. The anthropometrics, serum biochemistry profile, inflammatory cytokines, and three-day dietary assessment were analyzed according to sex, obesity degree, and ADD1 polymorphism. Results: The obesity prevalence was higher in boys (15.6%) than in girls (11.9%). Boys also showed higher values in anthropometrics; lipid, glucose, and insulin profiles; total calorie intakes, as well as those of sodium and calcium compared with those of the girls. The more obese were boys and girls, the higher were the anthropometrics and the blood levels (total cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting blood sugar, and insulin), but the lower was high-density lipoprotein cholesterol. The obese boys had significantly higher sodium and Na/K intakes, while the obese girls had higher visfatin level and Na/K intake. In addition, an increase in the risk factors for blood pressure and obesity in ADD1 variants was identified. Serum tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) significantly increased with increasing sodium intake in the ADD1 W allele carriers, regardless of sex. The presence of obesity with the ADD1 W allele induced inflammatory accelerators such as $TNF-{\alpha}$ or C-reactive protein(CRP) with higher sodium intake. Conclusion: Obese children with an ADD1w allele can experience a more complex form of obesity than non-obese when exposed to an obesity-inducing environment and need to be controlled sodium intake in the diet.

Dyslipidemia, defined as elevated triglyceride (TG), total- and LDL-C, and/or decreased HDL-C levels, is considered a principal risk factor for cardiovascular disease. The low-density lipoprotein receptor (LDLR) family has been considered a key player in the prevention of dyslipidemia. The LDLR family consists of cytoplasmic membrane proteins and plays an important role not only in ligand-receptor binding and uptake, but also in various cell signaling pathways. Emerging reports state that various functional ingredients dynamically modulate the function of the LDLR family. For instance, oats stimulated the LDLR function in vivo, resulting in decreased body weight and improved serum lipid profiles. The stimulation of LRP6 by functional ingredients in vitro activated the Wnt/${\beta}-catenin$ pathway, subsequently suppressing the intracellular TG via inhibition of SREBP1, $PPAR{\gamma}$, and $C/EBP{\alpha}$. Furthermore, the extract of Cistanchetubulosa enhanced the expression of the mRNA of VLDLR, followed by a reduction in the serum cholesterol level. In addition, fermented soy milk diminished TG and total cholesterol levels while increasing HDL-C levels via activation of LRP1. To summarize, modulating the function of the LDLR family by diverse functional ingredients may be a potent therapeutic remedy for the treatment of dyslipidemia and cardiovascular diseases.

Objectives We investigated anti-obesity effects of Menthae Herba hydrosol in obese mice. Methods Animals were divided into four groups, and treatments were performed for 7 weeks. After the treatment, serum lipid profiles, weight and pathological morphology in liver, kidney, adipose tissue were measured. Also, hepatic protein and gene expression levels of lipid metabolism-related factors were analyzed. Results Body weight was decreased in P3% group. In P1% (group fed high-fat diet and 1% Menthae Herba hydrosol) and P3% (group fed high-fat diet and 3% Menthae Herba hydrosol) group, weight of white adipose tissue, serum levels of triglyceride and blood urea nitrogen were decreased, and weight of muscle was increased. Also, liver, kidney and epididymal adipocyte size were reduced in P1% and P3% group. Adenosine monophosphate-activated protein kinase was increased and sterol regulatory element binding protein-1c (SREBP-1c) was decreased in P3% group. mPeroxisome proliferator-activator receptor-γ, mMonocyte chemotactic protein-1 were decreased in P1% and P3% group. In P3% group, mSREBP-1c was decreased and mCarnitine palmitoyl transferase-1 was increased. And mUncoupling protein 1 in brown adipose tissue was increased. Conclusions These results suggest that Menthae Herba hydrosol has a worthy effect on anti-obesity.

Purpose: Obesity is related to systemic inflammatory processes causing cardiovascular complications. Intercellular adhesion molecule-1 (ICAM-1), CD40 ligand (CD40L), P-selectin are newly described mediators of inflammation and have a significant effect in atherosclerosis. Adiponectin has shown anti-inflammatory effects in adults. The aim of this study was to evaluate the relationship between adiponectin and inflammatory mediators in children and adolescents. Methods: Fifty children or adolescents, twenty two with a body mass index (BMI) over 95th percentile, and twenty eight with a BMI below 75th percentile were included in the study. Serum soluble ICAM-1 (sICAM-1), P-selectin, CD40L, lipid profiles, aspartate aminotransferase, alanine aminotransferase, glucose and insulin were measured to evaluate associations with adiponectin. Comparison of these variables was performed between the obese and the nonobese group. Results: We found a adiponectin to be significant lower and sICAM-1 significant higher in the obese group compared to the nonobese group, but there were no significant differences in P-selectin and soluble CD40L. Adiponectin was negatively associated with ICAM-1 and P-selectin in the obese group. Conclusion: Negative associations of adiponectin with ICAM-1 and P-selectin in obese children and adolescents suggest that serum adiponectin level may represent the inflammatory status.

For the first 42 days, we made rats obese by feeding them potato starch instead of corn starch and after that we fed them transformed potato starch by 4 groups for 70 days. The 4 groups are GPS group, SPS group, EZ group and H40 groups and each were fed normal potato, small potato, enzyme treated potato, and acid treated potato starches, respectively. We determined body weight and feeding efficiency, lipid profiles in serum, lipid peroxidation in tissues and redox antioxidant system as GSH and GP-x in vivo. As a result, there was no difference in the increment of body weight in the groups of GPS, EZ and H40. Therefore EZ group showed lower body weight increment than other groups. While GPS group and SPS group did not show significant difference in blood glucose, cholesterol level, LDL-cholesterol and TC, and their measured values were lower than those of EZ and H40 groups. No significant difference was found in HDL-cholesterol level except for GPS group. Furthermore, when calculating atherogenic index (AI) by HDL-cholesterol and TC contents, H40 group showed higher measured value than other groups. When measuring the lipid peroxidation in serum, kidney and liver tissues, the serum lipid peroxidation in H40 group was higher than others. In the tissue of liver and kidney, EZ and H40 groups showed significantly lower contents than others. The content of GSH showed different tendency in each tissue, but the measured value of GP-x activity was lower in SPS group.

Aralia contientalis show several beneficial effects including anti-oxidant effects. Aralia contientalis is used as a therapeutic agent to stop haemorrhages and a tonic to promoted health in Korean and Chinese medicine. The pharmacokinetic profiles of the main Aralia contientalis is still not accurately investigated. In present study, I examined the effects of water extracts of Aralia contientalis on high cholesterol diet atherosclerosis-induced rats in serum and abdominal aorta. A total of 3-week old 9 male rats of Sprague-Dawley were divided into 3 groups and fed with the basal diet (normal group), high cholesterol diet (atherosclerosis induced group) for 8 weeks, high cholesterol diet supplemented with water extracts of Aralia contientalis (Aralia contientalis group) for 2 weeks. And rats were sacrificed, serum lipid level, abodominal aortic anti-oxidant activities and lipid peroxide were measured. These results indicated that serum total cholesterl, LDL-cholesterol, triglycerides concentration significently lowered in Aralia contientalis group than high cholesterol diet group. But HDL-cholesterol concentraion significently higher in Aralia contientalis group than high cholesterol diet group.

Dietary effects of chicken treated with Hwangki-Beni Koji sauces (HBS) on serum and hepatic lipid profiles in rats fed high a fat and high cholesterol diet were investigated. Experimental plots (5 rats per each group) were divided into normal control diet group (NC), high fat and high cholesterol diet group (HFC), HFC plus 15% base sauce treated chicken supplemented diet group (HFC-BS), HFC plus 15% HBS-treated chicken supplemented diet group (HFC-HBS), and fed for 5 weeks. Feed intakes in HFC-HBS group were higher than those of HFC and HFC-BS groups, whereas body weight gain and feed efficiency ratio of the HFC-HBS group were lower than those of the HFC and HFC-BS groups. Serum alanine aminotransferase and aspartate aminotransferase activities of HFC-HBS group were significantly lower than those of HFC and HFC-BS groups. Level of serum triglyceride, total cholesterol and LDL-cholesterol in HFC-HBS group were 34.06%, 6.28% and 31.00% lower than those of HFC-BS group, respectively, whereas HDL-cholesterol level and atherogenic index in HFC-HBS group were 1.72-fold higher and 2.52-fold lower, respectively, than those of HFC-BS group. Level of hepatic total lipid, triglyceride and total cholesterol in HFC-HBS group were 9.53%, 5.25% and 22.20% lower than those of HFC-BS group, respectively. In the morphological results of liver, the hepatocytes of central vein lesion and intact hepatic cell plate are preserved well from steatosis in HFC-HBS group, whereas the hepatocytes in HFC and HFC-BS groups are distended by accumulation of multiple fat droplets, and sinusoids are occluded. In the above results, we expected that chicken treated with Hwangki-Beni Koji sauce may have functionalities of anti-obesity, anti-cholesterol and also, lowering anti-atherogenic index in high fat and high cholesterol diets.
