This study was carried out to evaluate the supplementation effect of dietary natural plant extracts (NP: $Coxynil^{(R)}$, $Growell^{(R)}$ and $Respowell^{(R)}$) on broiler chickens. Forty thousand male broilers with 7 days adaptation after hatching were fed experiment diets for 34 days. The supplementation effects of NP on growth performance, blood parameters and biopsy were examined with twenty thousand broilers as the treatment group. Twenty thousand broilers for the control group (CON) were fed the diet with salinomycin-6, clopidol-25, enramycin-1, and BMD-2.5. In the diet of the treatment group, the antibiotics were replaced with 0.03%, 0.035% and 0.03% of $Coxynil^{(R)}$, $Growell^{(R)}$ and $Respowell^{(R)}$, respectively. The weight gain of the treatment group was increased but the feed intake was decreased, indicating that feed efficiency was increased compared to the CON. The mortality of the NP group was also lower compared to the CON group (1,008 birds to 1,693 birds), showing positive dietary effects from natural plant extracts. In the activity of infectious bursal disease virus (IBDV) and new cattle disease virus (NDV) antibodies, the NP showed lower antibody titer levels for both of IBDV and NDV compared to the CON. The levels of total cholesterol, HDL-cholesterol, globulin, and IgG in blood did not show significant differences between the groups. In the microscopic tissue analysis, no significant differences were detected. These results may suggest that a complex of three natural plant extracts can be used as alternative antibiotics in broilers.
This study was conducted to evaluate the effect of Sikhe made by medicinal herb on the functional level of liver. Water extract I (12.9% W/W) and II (25.8% W/W) were obtained from medicinal materials: Caragana Sinica, Glycyrrhiza uralensis, Atractylodes rhizoma alba, Atractylodes rhizoma alba, Crataegus pinnatifida, Paeonia lactiflora Pasll., Hordeum vulgare Linne, Oryza sativa Linne, ginger, peer and jujube. Experimental groups were divided into the control diet group (C), high fat diet group (HF), high fat diet treated with 5% extract I group (HFE I ) and high fat diet treated with 5% extract II group (HFE II). In sensory evaluation, overall quality scores associated with color, aroma, flavor and taste were significantly higher in water extract II than in water extract 1. After investigating functional and lipid levels of livers in rats, we found that the administration of water extract I or water extract II to the high fat diet group (HF) did not affect the gain of body weight but mildly reduced GOT or GPT activity in the high diet group. Moreover, administration of these medicinal herbal extracts significantly decreased the levels of total lipid, triglyceride and total cholesterol in the high fat diet group (HF). However, administration of these medicinal herbal extracts did not affect the level of phospholipid. In conclusion, as Sikhe made by medicinal herb slightly decreased the activity of GOT or GPT and amount of lipid in liver, prevention against high fat diet is thought to be important for liver protection.

Obesity is a pro-inflammatory state that contributes to the development of metabolic disorders such as hyperlipidemia, insulin resistance, type 2 diabetes, non-alcoholic fatty liver, and cardiovascular disease. In this study, we evaluated the inhibition of adipogenesis in 3T3-L1 cells and in high-fat diet (HFD)-induced obese mice by Peucedanum japonicum Thunberg L. water extract (PJT). Lipid accumulation measurement indicates that PJT markedly inhibited adipogenesis in a dose-dependent manner. RT-PCR results demonstrated that the mRNA expression of adipogenic transcription factors such as peroxisome proliferator-activated receptor-γ (PPARγ) and CCAAT/enhancer binding protein-α (C/EBPα) in 3T3-L1 cells were significantly down-regulated by PJT treatment. Oral administration of PJT (100, 300, and 500 ㎎/㎏, b.w/daily for 4 weeks) was conducted in high-fat diet induced obese mice and C57BL/6 mice. The PJT-administered group of HFD-induced mice had a lower body weight gain, along with decreased serum levels of glucose, triglycerides, and total cholesterol compared with the control mice, however, the HDL-cholesterol/total cholesterol ratio was increased. Furthermore, the elevated mRNA expression levels of adipogenesis related genes in the white adipose tissue of obese mice were significantly suppressed by PJT. These results indicate that PJT exhibits anti-obesity effects in obese mice by decreasing in serum lipid levels and lipogenesis related gene.
Terminal pediatric patient include congenital metabolic abnormalities, chromosome aberrations, congenital anomalies, neuromuscular diseases and other incurable conditions as well as malignant tumors. One third of these diseases are cancers, and two thirds of cancers are lymphadenoma and leukemia. Terminal pediatric patient may feel fear, anger and frustration against treatment process in hospitals, lose control of themselves and stay in helplessness due to restrictions within controlled hospital environment. This study examined the relationship between hospitalized childrens behavior and music using Contextual Support Model of Music Therapya theory stating therapeutic music environments possess three elements of Structure, Autonomy support and Involvement, and increase childrens active engagement. Focused on these three therapeutic elements, this study analyzed music therapy cases of terminally ill children to examine the relationship between childrens behavior and music as environmental supportive medium in the environment. This study is on a single case case subject, a 10-year-old girl with acute lymphocytic leukemia. Nine sessions of music therapy activities were conducted and analyzed using qualitative method. Focusing on three therapeutic elements of Contextual Support Model, analysis of sessions was made on the basis of activities specifically designed for this study. Main music therapy activities included singing while playing musical instruments, singing while listening to music through CD player, making up songs, and searching for song lines. The findings of this study are as follows: a) in terms of Structure, music therapy suggested a direction for effective musical activities for terminally ill children by providing environments where child can sing, play musical instruments and make up songs; b) in terms of Autonomy support, music therapy encouraged childs voluntary participation by giving her chances to make choice while singing or playing musical instruments; c) in terms of Involvement, child could gain positive approval of the therapist and conduct musical activities in cooperation with the therapist. Music therapy serves as supportive medium in the environment, develops spontaneity and self-reliance in emotionally depressed children, and promotes voluntary attitudes in the restricted hospital environment. Based on the positive effects of music therapy, more studies need to be conducted with an approach to more various terminal pediatric patients.

Chitosan, which is a biopolymer, composed of glucosamine units linked by β-l, 4 glycoside bonds, is rich in shells of crustacean such as crabs and shrimps. We examined effects of dietary chitosan on blood and tissue levels of lead, iron, zinc and calcium in lead administered rats. Male Sprague-Dawley rats were divided into 4 groups (n=32). Basal diet group was fed 3% cellulose diet and lead administered groups were fed 0%, 3% and 5% chitosan diets, respectively for 8 wks. To lead administered groups, lead (20㎎/day) was given three times per week by oral injection. Blood, liver, kidney and femur were collected for lead, iron, zinc, and calcium analyses. There was no significant difference in weight gain and food intake among groups. Blood and femur lead levels were lower in lead administered groups fed 3% and 5% chitosan diets than in lead administered control (0% chitosan diet) group (p<0.05). Blood and liver levels of iron and zinc in lead administered group fed 5% chitosan diet were significantly lower than those in basal diet group (p<0.05), but those in lead administered group fed 3% chitosan diet were not significantly different with those in basal diet group. These results show that chitosan diets have beneficial effects on lowering the accumulation of lead, but high chitosan diet may have negative effects on mineral levels.

This study was conducted for the antihyperlipidemic effect of ethanol extract from Portulaca oleracea in high fat diet-induced obese mice after having injected the ethanol extract from Portulaca oleracea to the obese mice with high fat diet. The 30 six-week-old male C57BL/6J mice were divided into 3 groups of 10 and fed for 5 weeks to be obese with high fat diet. Thereafter, for 4 weeks, ethanol extract from Portulaca oleracea was provided through oral injection to the 3 groups: control group (HFD), group injected with 75 mg/kg of ethanol extract from Portulaca oleracea (HFD+POE 75) and the group injected with 125 mg/kg of ethanol extract from Portulaca oleracea (HFD+POE 125). The serum and liver lipid and the alanine transaminase (ALT) and aspartate transaminase (AST) activity were measured. The result showed that there was no significant difference in weight gain and feed intake, and the feed efficiency ratio was significantly low in the group provided with ethanol extract from Portulaca oleracea. Serum total cholesterol was significantly low in the group of ethanol extract from Portulaca oleracea (HFD+POE 125). It appeared that all the groups provided with ethanol extract from Portulaca loeracea reduced plasma triglyceride significantly according to the ethanol extract from Portulaca oleracea dose. There was no dose dependency of HDL-cholesterol to the dose of ethanol extract of Portulaca oleracea. LDL-cholesterol was low in the group dosed with high ethanol extract from Portulaca oleracea (HFD+POE 125). There was difference of total cholesterol, triglyceride and total lipid contents in liver. AI (atherogenic index) and CRF (cardiac risk factor) were significantly low in the group with high dose of ethanol extract from Portulaca oleracea (HFD+POE 125). There was no difference of serum AST activity, however, serum ALT activity was significantly low in the group with high dose of ethanol extract from Portulaca oleracea (HFD+POE 125).
With the development of Internet and popularization of smartphones over recent years, social network services are experiencing rapid growth. On top of this, smartphone gaming market is showing a rapid growth and the use of mobile social games is on the significant rise. The occurrence of game data manipulation targeting these services and personal information leakage is highlighting the importance of social gaming security. This study is intended to propose development plans effective and efficient in social game services by figuring out factors putting effects on security dependent behavior of social game users in Korea and carrying out a practical study on the casual relationship between factors influencing security dependent behavior through recognized behavioral control and attitudes for privacy infringement of these factors. To do this, proposed was a study model in which the HBM(Health Belief Model) allowing the social game user to influence security dependent behavior was expanded and applied as a major variable. To verify the study model of this study practically, a survey was conducted among university students in Seoul-based K University and S University who had experienced using social game services. According to the study findings, firstly, the perceived seriousness turned out to provide positive influence to trust. But, the perceived seriousness turned out not to put positive effects on self-efficacy. Secondly, the perceived probability turned out not to put positive effects on self-efficacy and trust. Thirdly, the perceived gain turned out to put positive effects on self-efficacy and trust. Fourthly, the perceived disorder turned out not to put positive effects on self-efficacy and trust. Fifthly, self-efficacy turned out to put positive effects on trust. But, self-efficacy turned out not to put positive effects on security dependent behavior. Sixthly, trust turned out not to put positive effects on security dependent behavior. This study is intended to make a strategic proposal so that social game users can raise awareness of their level of security perception and security willingness through this.
Background: Regardless of its causes, acute lung injury is characterized pathophysiologically by increased pulmonary arterial pressure and the protein-rich edema. Many inflammatory mediators are known to be involved in the pathogenesis of acute lung injury, including oxygen free radicals (OFR). But the changes in pulmonary capillary pressure in the OFR-induced acute lung injury is not clear. While the pulmonary edema characterized by the movement of fluid and solutes is dependent on the pressure gradient and the alveolar-capillary permeability, the role of pulmonary capillary pressure in the development of pulmonary edema is also not well understood. Method: Male Sprague-Dawley rats were divided into 5 groups: normal control (n=5), xanthine/xanthine oxidase (X/XO)-treated group (n=7), catalase-pretreated group (n=5), papaverine-pretreated group (n=7), and indomethacin-pretreated group (n=5). In isolated perfused rat lungs, the sequential changes in pulmonary arterial pressure, pulmonary capillary pressure by double occlusion method, and lung weight as a parameter of pulmonary edema were determined. Results: Pulmonary arterial pressure and pulmonary capillary pressure were increased by X/XO. This increase was significantly attenuated by catalase and papaverine, but indomethacin did not prevent the X/XO-induced increase. Lung weight gain was also observed by X/XO perfusion. It was prevented by catalase. Papaverine did not completely block the increase, but significantly delayed the onset. Indomethacin had no effect on the increase in lung weight. Conclusion: These data suggest that increased pulmonary capillary pressure by OFR may aggravate pulmonary edema in the presence of increased alveolar-capillary permeability and this may not be mediated by cyclooxygenase metabolites.

The anti-diabetic effects of Allium tuberosum Rottler extracts (ATE) and ATE fermented with lactic acid bacteria in db/db mice were evaluated. The electron donating activity of ATE fermented with Lactobacillus plantarum, and Lactobacillus casei, respectively, increased compared to that of ATE, but the superoxide radical scavenging activity of the ATE incubated with L. plantarum decreased. The superoxide radical scavenging activity of the ATE fermented with both L. plantarum and L. casei was similar to that of the ATE. Therefore, fermented ATE (FATE) was prepared for in vivo testing by incubating it with both L. plantarum and L. casei. The db/db mice were divided into six groups: normal (non-diabetic mice), diabetic control (DM), and four experimental groups administered 200 or 400 mg/kg/day ATE (ATE200 and ATE400) and 200 or 400 mg/kg/day FATE (FATE200 and FATE400). Weight gain was significantly inhibited in the FATE200 group compared with that in the other db/db mice groups (p<0.05). The areas under the curve of the ATE400 and FATE400 groups were significantly smaller than that of the DM group in the glucose tolerance evaluation. The serum glucagon-like peptide-1 levels in the ATE400 and FATE400 groups increased. These results indicate that administering ATE and FATE may be effective against anti-hyperglycemia by regulating insulin resistance. In particular, FATE may be beneficial for controlling obesity in type 2 diabetes.
This experiment was carried out to investigate the nutritive value of brewery's activated sludge on the performance and nutrients utilization of egg type chicken of babcock fed the different levels of sludge. The chemical composition, content of amino acids and mineral in brewery's activated sludge were also analyzed. 3,6,9 and 12% of brewery's activated sludge were supplemented with basal ration as a substituted ingredient to soybean oil meal in experimental ration. The results obtained were as follow: 1. Chemical composition analysis 1) Brewery's activated sludge had 42.50% of crude protein on the air dried basis, and had 15,69% of crude ash, and had 2,060 kcal of metabolizable energy per kg of sludge. 2) Total amino acid content of brewery's activated sludge was 42.50% and 99% crude protein of brewery's activated sludge was a true amino acid, and brewery's activated sludge contained especially more methionine and threonine that those of soybean oil meal. 3) In case of mineral content of brewery's activated sludge, phosphorus, magnesium, copper and iron were plentifully included. However, calcium content in brewery's activated sludge was very low. 2. Feeding trial 1) Body gain of chicken fed the different levels of sludge was decreased in proportion to increasing level of sludge was decreased in proportion to increasing level of sludge. However, no statistical differences were found out between treatments. 2) Diet intake of chicken fed the different levels of sludge was significantly (p<0.05) increased as the supplementation level of sludge in ration increased. 3) Feed conversion of chicken fed the different levels of sludge was high in proportion to increasing level of sludge in ration. However, there were no significant differences between treatments. 3. Digestion trial 1) Utilization of dry matter of chicken fed the different levels of sludge was decreased as the level of sludge in ration increased. However, no statistical differences were found out between treatments. 2) Utilization of crude protein of chicken fed the different levels of sludge was significantly (p<0.01) increased as the level of sludge was higher. Utilization of crude protein of control treatment and of sludge 3% treatment was higher than that of other treatments. 3) Utilization of crude ash of chicken fed the different levels of sludge was significantly (p<0.05) decreased in proportion to increasing level of sludge in ration. 4) Utilization of NFE of chicken fed the different levels of sludge was slightly decreased in proportion to increasing level of sludge in ration. However, no statistical differences were found out between treatments. Therefore according to this experiment, it may be concluded that brewery's activated sludge can be supplemented with chicken ration by $6{\sim}9%$.
