The objectives of this study were to investigate the effects of dietary fish oil inclusion on the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) contents and organoleptic characteristics of breast meat in mule ducks. Three hundred mule ducks at four weeks of age were randomly assigned to three dietary treatments with five replicate pens in each. One replicate pen had ten males and females each with a total of 100 ducks in each treatment. The diet in the three treatments contained 0, 1.5, and 3.0% fish oil, respectively. Body weights at 4, 6, 8, and 10 weeks of age, and feed efficiency at 4 to 6, 6 to 8, and 8 to 10 weeks of age were recorded. At 10 weeks of age, one male and one female from each replicate were sacrificed for oxidative stability of breast meat and the sacrificed males were employed for the analysis of fatty acids in breast meat and skin. Sensory evaluation of breast meat was also performed. A level of 3.0% fish oil in the diet significantly deteriorated feed efficiency and body weight gain. Dietary fish oil inclusion had a trend of increasing abdominal fat deposition and decreasing the flavor of breast meat. The EPA and DHA contents in the breast meat were higher than those in the breast skin irrespective of oil sources. The EPA and DHA contents in breast meat and breast skin was significantly increased in the 3.0% fish oil group. Although EPA and DHA were not efficiently deposited in the duck meat through dietary fish oil inclusion, this method can still provide a partial supplementation of EPA and DHA.

In beef, the composition of saturated and unsaturated fatty acids(UFA) were 41.1% and 56.7%, respectively. The rates of saturated fatty acid (SFA) was 36.3, 40.9, 39.2 and 48.1% in loin, picnic shoulder, ham and rib, respectively. However, UFA showed 62.3, 58.4, 56.8, 50.9% in loin, picnic shoulder, ham and rib, respectively. The rates of monounsaturated fatty acid (MUFA) were similar to those of unsaturated fatty acid in four portions. The content of SFA, UFA and polyunsaturated fatty acid(PUFA) were 40, 59 and 9.4%, respectively, in pork. In portional comparison, composition of unsaturated fatty acids in picnic shoulder, ham rib and loin were 64.2, 60.4, 54.6 and 55.3%, respectively. The UFA contents of rib and loin were lower than picnic shoulder and ham, but SFA levels were higher. Total UFA content of chicken was 62.9% showing higher level than other species, but low when compared to that of duck meat. SFA content resulted in lower level than other portions. In the skin of chicken, MUFA content was especially high showing no significant changes in UFA contents. Duck meat showed lower SFA content, but higher content in UFA compared to those of other species. Skin and thigh contained 31.8 and 31.5%, respectively, in SFA, which are lower level than those of breast and thigh meat. The UFA contents of skin and thigh were 67.4 and 67.7%, respectively, which are relatively high compared to those of other portions. Meanwhile, the ratio of UFA was not high in canis meat compared to other meat. PUFA was, however, 24.2% showed significantly different from other meats. The contents of SFA were 35.4% and 35.9%, respectively, in picnic shoulder and ham. They showed lower SFA but higher UFA content than those of rib and loin. In contrast, the ratio of picnic shoulder and ham were 61.6 and 61.4%, respectively. Interestingly, picnic shoulder showed higher UFA content, especially in arachidonic acid level than other portions.

Objectives: Reactive Oxygen Species(ROS) are continuously produced at a high rate as a by-product of aerobic metabolism. Since tissue damage by free radical, ROS such as hydrogen peroxide($H_2O_2$), nitric oxide(NO) increases with age. Several lines of evidence provided that ROS appears to cause to develop aging-related various diseases such as cancer, arthritis, cardiovascular disease. In this study, we have conducted to investigate the pharmacological effects of red ginseng for the development possibility to pharmacopuncture drug sources or healthy aid foods. Methods: For our aims, it was investigated the biological activities of Red Ginseng ethanol extracts (RGEE) by measuring total polyphenol contents, total flavonoid contents, DPPH radical scavenging activity, ABTS radical scavenging activity and cell viability of MCF 10A and SK-MEL-2 in vitro with MTT assay method. Results: The total polyphenol contents of RGEE was 3.06${\pm}$0.11mg/g in 10mg/ml, the total flavonoid contents of RGEE was 1.35${\pm}$0.01mg/g in same concentration. The ABTS radical scavenging activity was about 80% and that of DPPH activity was 65% in 50mg/ml of RGEE. The cell viability of SKMEL-2, skin cancer cell line was decreased and that of MCF 10A, skin normal cell line was increased. Conclusions: We conclude that RGEE may be useful as potential functional foods or pharmacopuncture drug sources on the diseases induced by oxidant stress.

We investigated the skin permeability and various biological activities of porcine homogenate of placenta (HP) with the highest protein contents (452.89 ${\mu}g/mg$). The content of protein in subcritical extract of HP (SPE) was decreased from the initial content of 452.9 ${\mu}g/mg$ to 262.7 ${\mu}g/mg$ at 3 h subcritical extract. The contents of amino type nitrogen (A-N) were sharply increased from 35.1 ${\mu}g/mg$ of initial content to 305.9 ${\mu}g/mg$ at 3 h subcritical extract. The HP showed a noticeable activity in terms of antioxidant capacity for ferric reducing antioxidant power (FRAP) assay and especially for 2,2'-Azinobis- (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) method. HP, SPE-0.5, SPE-2 and SPE-3 showed inhibitory effect on elastase activities with an $IC_{50}$ of 46.1, 42.9, 31.6 and 34.7 ${\mu}g/mL$, respectively. SPEs showed more significantly inhibitory effect than HP (p<0.05). The skin permeability of the SPEs was higher than that of the HP. SPE-3 showed highest skin permeation and the permeability was significantly higher than that of HP. SPE-2 also showed significantly higher permeation than HP after 4 h. As expected, increase of extraction time significantly increased skin permeability in the subcritical extract of HP (SPE). From these results, in terms of cost and source availability, porcine placenta extracted with subcritical extraction has advantages over untreated PE and have potential as a cosmetic ingredient.

Two feeding experiments were conducted to investigate the effects of dietary paprika (DP) and lipid (DL) levels on growth performance and skin pigmentation of pale chub, Zacco platypus. Six diets (designated as $P_0L_8,\;P_0L_{17},\;P_8L_8,\;P_8L_{17},\;P_{16}L_8\;and\;P_{16}L_{17}$) were formulated to contain 0%, 8% and 16% paprika with 8% and 17% lipid, respectively. For the growth experiment (Exp I), three replicate groups of fish (average weight 2.6${\pm}$0.2 g) were fed one of the six experimental diets for 8 weeks. At the end of the feeding period, survival was above 94% and not significantly different among dietary treatments. Weight gain, feed efficiency and protein efficiency ratio of fish fed the $P_{16}L_8$ diet were lower than for fish fed the $P_0L_8$ diet. The highest total carotenoid (TC) content was observed in fish fed the $P_{16}L_8$ diet. For the pigmentation experiment (Exp II), each experimental diet was fed to two replicate groups of fish (average weight 9.0${\pm}$0.5 g) for 8 weeks. At the end of the feeding period, TC content of the skin was significantly affected by DP (p<0.05). The highest TC content of the skin was observed after 6 weeks of feeding at all dietary treatments. Astaxanthin content of the skin was not affected by DP and DL (p>0.05). The capxanthin and zeaxanthin contents of skin increased significantly with increasing DP, whereas the opposite trend was observed for lutein and ${\beta}$-cryptoxanthin contents. The skin lightness ($L^*$ values) significantly decreased whereas the values of $a^*$ and $b^*$ were significantly increased in fish fed the diets containing paprika (p<0.05). The present results suggest that feeding a diet containing 8% paprika and 8% lipid for 6 weeks could improve skin pigmentation of pale chub without any adverse effects on growth performance.
