  • This experiment was conducted to investigate the effects of pelleted food waste on performance and meat quality of broiler ducks. One hundred-forty four broiler ducks were divided into 4 groups with 3 replicates per treatment for 5 weeks. Dietary levels of food waste 0%, 25%, 50% and 75% were included in experimental diets Daily weight gain was significantly increased by addition of food waste 25% and .50%, whereas decreased(P<0.05) by addition of 75% food waste. Feed intake were not affected by the pelleted food waste supplementations. Feed efficiency was improved(P<0.05) by the addition 25% food waste, however, there was depressed(P<0.05) by the addition of 75% food waste. Carcass weight was significantly decreased(P<0.05) by the addition 75% food waste. Moisture composition of breast meat were not significantly different by 25% and 50% food waste, however, there was significantly increased by 75% food waste. As the food waste level was increased, lipid and protein composition in beast meat was significantly decreased As the food waste level was increased. pH of beast meat was increased, whereas lightness and redness of meat color were decreased. Cholesterol content was significantly decreased(P<0.05) by addition of food waste. Odor and appearance of sensory evaluation was depressed by addition of food waste, whereas taste of sensory evaluation was improved by addition of food waste. There was no pathological findings from liver, spleen and kidney in slaughtered ducks. The results of this study suggests that pelleted food waste 25% and 50% improved broiler ducks performance and meat quality in broiler ducks.

  • Objectives: The effects of peroxisome proliferator-activated receptor ${\gamma}2\;(PPAR{\gamma}2)$ Pro12Ala (P12A) polymorphism on body mass index (BMI) and type 2 diabetes are well documented; however, until now, only a few studies have evaluated the effects of this polymorphism on body fat distribution. This study was conducted to elucidate the effects of this polymorphism on computed tomography (CT)-measured body fat distribution and other obesity-related parameters in Korean female subjects. Methods & Results: The frequencies of $PPAR{\gamma}2$ genotypes were: PP type, 93.0%; PA type, 6.8%; and AA type, 0.2%. The frequency of the A allele was 0.035. Body weight (P .012), BMI (P .012), and waist-to-hip ratio (WHR) (P .001) were significantly higher in subjects with PA/AA compared with subjects with PP. When body composition was analyzed by bioimpedance analysis, lean body mass and body water content were similar between the 2 groups. However, body fat mass (P .003) and body fat percent (P .025) were significantly higher in subjects with PA/AA compared with subjects with PP. Among overweight subjects with BMI of greater than 25, PA/AA was associated with significantly higher abdominal subcutaneous fat (P .000), abdominal visceral fat (P .031), and subcutaneous upper and lower thigh adipose tissue (P .010 and .013). However, among lean subjects with BMI of less than 25, no significant differences associated with $PPAR{\gamma}2$ genotype were found, suggesting that the fat-accumulating effects of the PA/AA genotype were evident only among overweight subjects, but not among lean subjects. When serum lipid profiles, glucose, and liver function indicators were compared among overweight subjects, no significant difference associated with $PPAR{\gamma}2$ genotype was found. Changes in body weight, BMI, WHR, and body fat mass were measured among overweight subjects who finished a 1-month weight lose program of a hypocaloric diet and exercise; no significant differences associated with $PPAR{\gamma}2$ genotype were found. Conclusions: The results of this study suggest that the $PPAR{\gamma}2$ PA/AA genotype is associated with increased subcutaneous and visceral fat areas in overweight Korean female subjects, but does not significantly affect serum biochemical parameters and outcomes of weight loss programs.

  • Hyperlipidemia has been reported to be associated with the development of fatty liver. Palmitic acid, a major saturated fatty acid, is involved in the development of diverse diseases. The activation of mitogen activated protein kinases (MAPKs), such as Jun N-terminal kinase (INKs) and p38 MAPK is implicated in the apoptosis in diverse cells. Thus, this study was conducted to investigate the effects of palmitic acid on apoptosis and its relationship between JNK and p38 MAPK in cultured rat hepatocytes. In the present study, palmitic acid (>50 uM) decreased cell proliferation and increased lactate dehydrogenase activity in hepatocytes, which was blocked by the treatment of SP600125 (a JNK inhibitor) and SB203580 (a p38 MAPK inhibitor). Indeed, palmitic acid decreased Bcl-2 expression but increased Bax expression in rat hepatocytes, which was blocked by the treatment of SP600125 and SB203580. In addition, palmitic acid decreased glutathione (GSH) content and increased lipid peroxide formation, which was blocked by the treatment of SP600125 and SB203580. Western immunoblotting analysis also revealed that palmitic acid increased JNK and p38 MAPK. In conclusion, palmitic acid induced apoptosis through oxidative stress via JNK and p38 MAPK activation in rat hepatocytes.

  • In this study, the clinical safety and toxicology of oral ingestion of supplement capsules containing ginseng radix was investigated in healthy young volunteers. This study was a pilot randomized, double blinded, placebo controlled trial. The healthy volunteers were divided into 6 groups of 20 each (10 males and 10 females). They took the ginseng powder for 35 days (3g/day) for safety evaluation. There were measured general healthy levels such as hematological, biochemical and electrocardiographic parameters. After the first week, besides Korean white ginseng the other treatments led to an significant increase of white blood cells. Korean red ginseng increased UREA (blood urea nitrogen) in healthy volunteers, but it didn't exceed the range of normal values, and in the subsequent process of treatment there is no effect of elevating UREA. After the three weeks, Korean white ginseng showed relatively low the content of blood glucose and low-density lipoprotein cholesterol. After the five weeks, compared with the other treatments, Korean red ginseng increased white blood cells, platelet distribution width and average volume of platelet. Korean white ginseng decreased low-density lipoprotein cholesterol. American ginseng decreased blood creatinine in healthy volunteers. In conclusion, through test the blood routine, urine routine, liver function, renal function, blood glucose, blood lipid and electrocardiogram, the healthy volunteers continuous taking ginseng for 35 days (3 g/day) is safe and reliable, and have no obvious adverse reactions and side effects.

  • Dung beetle (Catharsius molossus, CA) is a well-known group of insects thanks to their exploitation of animal feces, a behavioral trait with a global impact on earth′s ecosystems. This study was conducted to investigate the effect of CA extract on a high-fat diet in SD rats. Male rats were divided into 5 groups. Animals were fed on a high-fat diet for seven weeks before and dung beetle extract for a month during the administration. Weight gain was decreased in ethanol extract from CA group. Administration of CA extract reduced the organ weight of testis and kidney, and adipose tissue weight. Lipid oxidative stress was evaluated measuring malondialdehyde level in liver. There were no significant differences in groups. Protein oxidative stress was evaluated measuring protein carbonyl content in blood. The protein carbonyl in blood was significantly decreased in ethanol and acetone extracted dung beetle groups (p<0.05). Meanwhile, the protein carbonyl in hepatocyte was not significant among the groups. Fibronectin and laminin by using D-HUVEC cell in vitro were measured by ELISA assay. There was significance in CA extract. The level of IL-10, IL-1β, VEGF, eNOS was evaluated by ELISA. There was significance in IL-10 compared to control (p<0.05). SOD and GPx tended to increase by CA extract. Furthermore, CAT was increased significantly by CA extract (p<0.05). After administration of CA extracts the composition of saturated fatty acid in adipose tissue tend to decrease, while unsaturated fatty acid increases. In conclusion, dung beetle had anti-hyperglycemia effects of oxidative stress and antioxidant activity.

  • This study was conducted to investigate the effects of feeding seleniferous whole crop barley silage (WCBS) on the growth performance, blood and carcass characteristics, and tissue selenium deposition infinishing Hanwoo steers. A total of 20 growing Hanwoo steers were selected and assigned to one of the following feed groups: control (0.1 ppm Se), T1 (0.3 ppm Se), T2 (0.9 ppm Se), and T3 (0.9 ppm of inorganic Se). Five steers were allocated to each treatment group, and the trial lasted for 90 days. All experimental diets combined seleniferous and/or non-seleniferous WCBS up to a ratio of 30%. For the T3 diet, 0.9 ppm Se in the form of sodium selenite was added to the control diet. Dietary level and type of selenium did not affect feed intake and body weight gain. Blood total lipid and triglyceride concentrations were significantly (p<0.05) lower in the T2 group than in control. Blood immunoglobulin G concentration increased significantly (p<0.05) with increasing levels of dietary selenium; concentrations were significantly (p<0.05) higher in T2 and T3 than in control. Blood selenium concentration was the highest (p<0.05) in T2. No significant difference was observed in dressing rate, ribeye area, marbling score, meat color and fat color. Further, no association was found between levels and chemical form of dietary selenium and quality and quantity of meat. To the contrary, tissue selenium content in kidney, liver, and hind leg increased significantly (p<0.05) with increasing levels of selenium; however, feeding inorganic selenium did not introduce a significant increase in tissue selenium content of finishing Hanwoo steers. The results indicated that the selenium present in seleniferous WCBS was an effectively absorbable selenium source, suitable for increasing tissue selenium content in beef. Approximately 100 g of hind leg muscle from steers fed on the T2 diet met approximately 69% of the recommended daily selenium requirements.

  • Antioxidant activity and protective effects of extracts from Helianthus tuberosus L. leaves (HTL) on t-BHP-induced oxidative stress in human liver Chang cells were investigated. The total polyphenol and flavonoid content of the water and ethanolic extracts from HTL were 89.6${\pm}$1.96, 94${\pm}$2.03 mg gallic acid equivalent/g extract, and 65.1${\pm}$2.84, 54.6${\pm}$1.87 mg catechin equivalent/g extract, respectively. In addition, $IC_{50}$ values for 1,1-diphenyl-2-picrydrazyl (DPPH), alkyl, and hydroxyl radical scavenging activity of the water extracts were 0.010${\pm}$0.003 mg/mL, 0.014${\pm}$0.002 mg/mL, and 0.989${\pm}$0.003 mg/mL, respectively. Antioxidant activities of the extracts were also determined by ferric reducing antioxidant power (FRAP), 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity and reducing power. The HTL extracts showed a strongly inhibitory effect on lipid peroxidation by measuring ferric thiocyanate (FTC) and thiobarbituric acid (TBA) values. In an MTT assay on the Chang cells, the extracts showed a protective effect by increasing cell viability and decreasing ROS on t-BHP-induced oxidative stress in Chang cells. These results indicate that the HTL extracts possess an antioxidant activity.

  • This study was conducted to determine the effect of fermented water extracts from Ligularia fischeri (LAF) on reduction of hepatotoxicity induced by D-galactosamine (D-GalN) in rats. In this experiment, male Sprague-Dawley rats were used as experimental animals, which were divided into eight groups: normal group, D-GalN-treated group (control), D-GalN and non-fermented water extracts from Ligularia fischeri (LA)-treated groups [100, 200, and 400 mg/kg BW (body weight)], and D-GalN and LAF-treated groups (100, 200, and 400 mg/kg BW). ${\gamma}$-Glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase activities in serum of the D-GalN and LAF-treated groups decreased significantly compared to those of the control group (P<0.05). The high density lipoprotein-cholesterol levels of the D-GalN and LAF-treated groups increased significantly compared to those of the control group (P<0.05). The low density lipoprotein-cholesterol and triglyceride levels of the D-GalN and LAF-treated groups decreased significantly compared to those of the control group (P<0.05). The atherogenic index values of the D-GalN and LAF-treated groups decreased significantly compared to those of the control group (P<0.05), and their high density lipoprotein cholesterol by total cholesterol ratio increased significantly in these groups (P<0.05). Superoxide dismutase activity of liver tissues were enhanced significantly (P<0.05) in the D-GalN and LAF-treated groups compared to that of the control group (P<0.05), whereas their malondialdehyde content decreased significantly in these groups (P<0.05). The histopathological observations revealed apoptotic cells and mild portal inflammation in liver tissues of the D-GalN and LAF-treated groups. Taken together, these results demonstrate that LAF may improve plasma lipid profile and alleviate hepatic damage.

  • Uncoupling protein 3 (UCP3) is a mitochondrial protein that is expressed predominantly in skeletal muscle. It may play a role in altering metabolic function. However, its major physiological roles are not fully understood. Recently de novo expression of UCP3 in rat liver by fenofibrate was reported. We also reported previously that fenofibrate-induced de novo expression of UCP3 contributes to reduction of adipose tissue in obese rats. In the present study, we investigated that ienofibrate-induced expression of UCP3 in rat liver is related with metabolic function such as body weight and hepatic lipid content by time-dependent manner in high-fat diet rats. Eight-week-old male Sprague-Dawley rats were randomly divided into two groups; the high fat diet group (HF, n=16) and fenofibrate-treated high fat diet group (HFF, n=16). The mRNA expression of hepatic UCP3 was detected as early as 1 week of fenofibrate treatment by quantitative real-time PCR and the amount of mRNA was increased time-dependently. The mean body weight of the HFF group was significantly less com. pared with the HF group after 6 weeks of fenofibrate treatment, even though there was no difference of food intake between the two groups. Rectal temperature was increased during 4 to 6 weeks of fenofibrate treatment and body weight was decreased after 6 weeks of treatment. These results were corresponded with the increased amount of the expression of UCP3 mRNA and protein. We suggest that de novo expression of hepatic UCP3 is increased time-dependently with fenofibrate treatment and that the amount of expression is correlated with metabolic function.
