  • Objectives : In order to investigate the efficacy of BJBB on atopic dermatitis, various anti-inflammatory factors were studied. Methods : In-vitro, inflammatory mediators, such as MTT and nitric oxide were detected after the addition of LPS with or without BJBB in Raw 264.7 cells. In-vivo, in order to verify the effectiveness of BJBB in atopic dermatitis animal model, its role in inflammation factors and histological changes were observed in NC/Nga mice. Results : BJBB showed cell viability of 100% or higher in all concentration in Raw 264.7 cells. BJBB inhibited LPS-induced productions of inflammatory mediators nitric oxide in RAW 264.7cells. BJBB treated group showed significant decrease in the expression of IL-1b, IL-6 and TNF-a by 40%, 80% and 44% respectively. Also the group showed decrease in the transcription of IL-1b, IL-6 and TNF-a mRNA in spleen by 41%, 93% and 39% respectively. BJBB treated group showed significant decrease in WBC, neutrophil, lympocyte and monocytes immune cell ratio in blood by 54%, 63%, 57% and 86% respectively. BJBB treated group showed decrease in the expression of IgG by 39% respectively. Also, infiltration of adipocytes into skin was suppressed and the thickness of epidermis and dermis were relatively decreased in the BJBB treated group. Conclusion : BJBB has an anti-inflammatory effects in NC/Nga mouse. Thus, these results suggested a beneficial effect of BJBB in treatment with Atopic dermatitis and inflammatory.

  • Gami-Sopungsan (GS) is one of the traditional korean remedy. We investigated the anti-inflammation and anti-atopic dermatitis (AD) effect of GS. No cytotoxicity of GS was observed in the range of $1{\sim}100{\mu}g/m{\ell}$ on Raw 264.7 cells. The Inflammatory response of Raw 264.7 cells were induced by lipopolysaccharide (LPS), followed by GS treatment at indicated concentrations (0, 1, 10 and $100{\mu}g/m{\ell}$). At $100{\mu}g/m{\ell}$ concentration, GS showed inhibitory effect on LPS-induced nitric oxide production by 20%. Production of IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ was decreased by approximately 56%, 36% and 79%, respectively upon GS treatment at $100{\mu}g/m{\ell}$. 200 mg/kg of GS was orally administered to NC/Nga mice, where AD was induced by 1-chloro 2,4-dinitrobenzene. There were no significant difference between GS treated group and the control group on body weight and food intake changes during growth. The back skin of GS group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. In addition, leukocyte infiltration and the thickness of epidermis were significantly decreased in the skin tissues (back and ear). The serum IgE levels were decreased by 28.8% in the GS treated group. The GS treated group showed remarkable inhibition of IL-4 (83%), IL-5 (95%), IL-6 (62%) and TNF-${\alpha}$ (84%) in serum, indicating that GS has similar or higher efficacy than those of the dexamethasone treated group. From the results above, we conclude that GS has significant anti-inflammation and anti-AD effects on Raw 264.7 cells and NC/Nga mice. The results should provide fundamental and valuable data for the research on natural products being developed against atopic dermatitis.

  • Objective: This experiment was conducted to evaluate the optimal space allowance on growth performance, blood profile and pork quality of growing-finishing pigs. Methods: A total of ninety crossbred pigs [$(Yorkshire{\times}Landrace){\times}Duroc$, $30.25{\pm}1.13kg$] were allocated into three treatments (0.96: four pigs/pen, $0.96m^2/pig$; 0.80: five pigs/pen, $0.80m^2/pig$; 0.69: six pigs/pen, $0.69m^2/pig$) in a randomized complete block design. Pigs were housed in balanced sex and had free access to feed in all phases for 14 weeks (growing phase I, growing phase II, finishing phase I, and finishing phase II). Results: There was no statistical difference in growing phase, but a linear decrease was observed on average daily gain (ADG, p<0.01), average daily feed intake (ADFI, p<0.01), and body weight (BW, p<0.01) with decreasing space allowance in late finishing phase. On the other hand, a quadratic effect was observed on gain to feed ratio in early finishing phase (p<0.03). Consequently, overall ADG, ADFI, and final BW linearly declined in response to decreased space allowance (p<0.01). The pH of pork had no significant difference in 1 hour after slaughter, whereas there was a linear decrease in 24 h after slaughter with decreasing space allowance. Floor area allowance did not affect pork colors, but shear force linearly increased as floor space decreased (p<0.01). There was a linear increase in serum cortisol concentration on 14 week (p<0.05) with decreased space allocation. Serum IgG was linearly ameliorated as space allowance increased on 10 week (p<0.05) and 14 week (p<0.01). Conclusion: Data from current study indicated that stress derived from reduced space allowance deteriorates the immune system as well as growth performance of pigs, resulting in poor pork quality. Recommended adequate space allowance in a grow-to-finish production system is more than $0.80m^2/pig$ for maximizing growth performance and production efficiency.

  • Optimal heat treatment conditions for maintaining the immune-activity of immunized milk with Helicobacter pylori antigen were studied Total bacterial count of immunized milk with H. pylori antigen decreased according to the increasing heating temperature and time. The viable tell number of immunized milk was $10^3\;CFU/mL$ after heat treatment for 30 min at $60^{\circ}C$, and coliform bacteria did not appear in immunized milk after heat treatment Immune-activity measured in terms of IgG concentration was maintained up to 99.99% after heat treatment for 30min at $60^{\circ}C$, but decreased rapidly below 50% after heat treatment above $70^{\circ}C$. The quality characteristics of immunized milk were examined during storage at $2^{\circ}C,\;4^{\circ}C\;and\;10^{\circ}C$. The pH, titratable acidity and total bacterial count were not changed significantly during 21 day storage at $2^{\circ}C\;and\;4^{\circ}C$, but rapidly changed after 7 day storage at $10^{\circ}C$. The immune-activity was kept well for 14 day storage at $2^{\circ}C,\;4^{\circ}C\;and\;10^{\circ}C$ but decreased rapidly after 14 days at every temperatures tested.

  • Purpose: This study was conducted to examine the concentration of nutrients in transitional breast milk from Korean lactating mothers and to evaluate daily intakes of their infants based on the Dietary Reference Intakes for Koreans 2010 (KDRIs 2010). Methods: Breast milk samples were collected at 5~15 days postpartum from 100 healthy lactating Korean mothers. Macro- and micro-nutrients, and immunoglobulin (Igs) concentrations in breast milk were analyzed. Results: The mean energy, protein, fat, and carbohydrate concentrations in breast milk were $59.99{\pm}8.01kcal/dL$, $1.47{\pm}0.27g/dL$, $2.88{\pm}0.89g/dL$, and $6.72{\pm}0.22g/dL$. The mean linoleic acid (LA), a-linolenic acid (ALA), arachidonic acid (AA), and docosahexaenoic acid (DHA) concentrations were $181.44{\pm}96.41mg/dL$, $28.15{\pm}8.89mg/dL$, $5.67{\pm}1.86mg/dL$, and $5.74{\pm}2.57mg/dL$. The mean vitamin A, vitamin D, vitamin E, vitamin $B_1$, vitamin $B_2$, vitamin $B_{12}$, and folate concentrations were $2.75{\pm}1.75{\mu}g/dL$, $2.31{\pm}1.12ng/dL$, $0.74{\pm}1.54mg/dL$, $3.02{\pm}1.84mg/dL$, $7.51{\pm}20.96{\mu}g/dL$, $61.78{\pm}26.78{\mu}g/dL$, $63.71{\pm}27.19ng/dL$, and $0.52{\pm}0.26{\mu}g/dL$. The mean concentrations of calcium, iron, potassium, sodium, zinc, and copper were $20.71{\pm}3.34mg/dL$, $0.59{\pm}0.86mg/dL$, $66.71{\pm}10.35mg/dL$, $27.72{\pm}10.16mg/dL$, $0.44{\pm}0.41mg/dL$, and $70.48{\pm}30.41{\mu}g/dL$. The mean IgA and total IgE concentrations were $61.85{\pm}31.97mg/dL$ and $235.00{\pm}93.00IU/dL$. The estimated daily intakes of infants for protein, vitamin D, vitamin E, vitamin $B_2$, vitamin $B_{12}$, iron, potassium, sodium, zinc, and copper were sufficient compared to KDRIs 2010 adjusted by transitory milk intakes. The estimated infants' intakes of energy, fat, carbohydrate, vitamin A, vitamin C, vitamin $B_1$, folate, and calcium did not meet KDRIs 2010 adjusted by transitory milk intakes. Conclusion: In general most estimated nutrient intakes of Korean breast-fed infants in transitory breast milk were sufficient, however some nutrient intakes were not sufficient based on KDRIs 2010. These results warrant conduct of future studies for investigation of important dietary factors associated with nutrients in breast milk to improve the quality of breast milk, which may contribute to understanding nutrition in early life and promoting growth and development of breast-fed infants.

  • Atopic dermatitis (AD) is a common skin disease characterized by chronic and relapsing inflammatory dermatitis with immunological disturbances. In spite of the continuous increase in the incidence of AD, it is regrettable that till date there is no effective treatment to treat the same. Therefore, the present study was designed to examine the possible anti-atopic effects of Castanea crenata inner shell extracts fermented by Lactobacillus bifermentans (FCS) in 2,4-dinitrochlorobenzene (DNCB) induced AD in NC/Nga mice. Based on the results of HPLC analysis, we found that FCS contains anti-inflammatory factors such as gallic acid (10.18 mg/g) and ellagic acid (2.14 mg/g). The groups that we have used in this study included 0.1%, 1%, 5% fermented Castanea crenata inner shell extracts (FCS 0.1, FCS 1, FCS 5), 1,3-butylene glycol treated control (AD), and normal mice. After topical FCS treatment, we observed that the clinical severity score for AD was lower in both the FCS 1 and FCS 5 groups than the AD group. We also proved beyond doubt that there was improvement of melanin, erythema and skin moisture indices in the FCS 5 group. Spleen index and gene expression levels of pro-inflammatory cytokines such as IL-$1{\beta}$ and TNF-${\alpha}$ were significantly decreased in the FCS 5 group compared to the AD group (P<0.05). Further, we also found that the level of serum immunoglobulin E (IgE) in the FCS-treated group was decreased in a concentration-dependent manner. The results of our study suggest that FCS can be effectively used as a cosmeceutical ingredient for both the prevention and improvement of AD.

  • This study was conducted to investigate the effects of dietary supplementation of multiple probiotics on the performance, small intestinal microflora and immune response in laying hens and broilers. In Exp.1, a total of 800, 82 wk old Hy-line Brown$^{(R)}$ laying hens were assigned to one of the following five dietary treatment; Control, Antibiotics (avilamycin 6 ppm), Probiotics; PB-M (Micro-ferm$^{(R)}$ 0.2%), PB-L (Lacto-sacc$^{(R)}$ 0.1%), PB-Y (Y University probiotics 0.2%). Each treatment was replicated eight times with 20 birds in each replicate and two birds were housed in each cage. Twenty birds units were arranged according to completely randomized block design. Feeding trial lasted 6 wk under 16 h lighting regimen. The Exp. 2, was conducted with a total of 1,000 broilers chicks (Ross$^{(R)}$). They were divided into five treatments, same as those of Exp. 1. Birds were fed starter (0~3 wk) and grower (4~5 wk) diets. Each treatment was replicated four times with 50 birds per pen comprising of deep litter. In Exp. 1, egg production parameters, such as hen-day and hen-house egg production, egg weight, broken and soft shell egg production, feed intake and feed conversion were not significantly different among treatments. However, strength and thickness of eggshell were significantly (P<0.05) different. Among the probiotics, PB-Y showed the highest strength and thickness of eggshell. Eggshell color, egg yolk color and Haugh unit were not significantly influenced. In Exp. 2, overall weight gain (0~5 wk) and mortality were not significantly different among treatments. However, weight gain of birds from PB-Y treatment during starter (0~3 wk) was significantly lower than the birds from Control and Antibiotic treatment. During the whole period (0~5 wk), birds from Antibiotics treatment had higher feed intake and Production Index (PI) and lower feed conversion than birds from Control treatment. Probiotics treatments were not significantly different from the Control on feed intake and feed conversion. In Exp.1, there were significant (P<0.05) differences in leukocytes parameters, such as white blood cell (WBC), hetrophil (HE), lymphocytes (LY), monocyte (MO), eosinophil (EO) and stress index (SI; HE/LY) in the blood of layers. Birds from Antibiotics and probiotics treatments tended to increase these parameters. In Exp. 2, however, only SI was significantly (P<0.05) decreased in Antibiotics treatments. Concentration of serum immunoglobulin (IgG) were higher (P<0.05) in PB-M and PB-Y treatments when compared with Control treatment in Exp. 1. The population of E. coli significantly (P<0.05) decreased in birds from Antibiotics, PB-L and PB-Y treatments when compared with birds from Control treatment in Exp. 1. Metalbolizability of crude fat decreased significantly (P<0.05) in birds from probiotic treatments in Exp. 2. It was concluded that the response of probiotics on the productivity of layers and broilers were different. Probiotics increased strength and thickness of eggshell in layers, and decreased feed conversion and increased PI in broilers. Leukocytes and IgG tended to increase by supplementation of antibiotics and probiotics in layers. Intestinal E. coli tended to decrease in layers. Digestibility of crude fat of diet decreased in probiotics treatments broilers. Parameters of blood and microbial were more sensitive in layers than broilers.

  • High levels of inflammatory cytokines were proposed contributors to the pathogenesis of a various inflammatory skin disorders. Therefore, investigating the immune response of the inflammatory skin disorder allows a better understanding of pathogenesis of a various inflammatory skin disorders and therapeutic approaches. The aim of this study was to analyze of the immune response in dogs with chronic inflammatory skin disease. To this aim, the present study evaluated relative mRNA expression of canine $IFN-{\gamma}$, IL-4, $TGF-{\beta}$ and IL-10 using TaqMan realtime PCR assays and semi-quantitative RT-PCR in freshly isolated peripheral blood mononuclear cells from twenty dogs with chronic inflammatory skin disease and ten normal dogs. The relative mRNA expression levels of IL-4 mRNA were significantly higher in dogs with chronic inflammatory skin disease than those in normal dogs (P < 0.01). The results of present study also showed a tendency towards increased expression of IL-10 transcripts in dogs with chronic inflammatory skin disease. However, there were no significant differences in the levels $IFN-{\gamma},\;TGF-{\beta}$ between normal and chronically inflammed dogs. In addition, the concentration of serum IgE was significantly increased in dogs with chronic inflammatory skin disease compared with those in normal dogs (P < 0.01). In histopathological examination, we found that there were markedly increased mast cell counts in chronically inflammed dogs (P < 0.05). These results suggest that the pathogenesis of chronic inflammatory skin disease might be associated with a T-cell mediated inflammatory responses characterized by a Th2-skewed immune response. Based on these results, the modulation of Th1/Th2 balance may be an effective therapeutic strategy for the treatment of chronic inflammatory skin disease.

  • Background: TRAIL (TNF-related apoptosis inducing ligand) is a newly identified member of the TNF gene family which appears to have tumor-selective cytotoxicity due to the distinct decoy receptor system. TRAIL has direct access to caspase machinery and induces apoptosis regardless of p53 phenotype. Therefore, TRAIL has a therapeutic potential in lung cancer which frequently harbors p53 mutation in more than 50% of cases. However, it was shown that TRAIL also could activates $NF-{\kappa}B$ in some cell lines which might inhibit TRAIL-induced apoptosis. This study was designed to investigate whether TRAIL can activate $NF-{\kappa}B$ in lung cancer cell lines relatively resistant to TRAIL-induced apoptosis and inhibition of $NF-{\kappa}B$ activation using proteasome inhibitor MG132 which blocks $I{\kappa}B{\alpha}$ degradation can sensitize lung cancer cells to TRAIL-induced apoptosis. Methods: A549 (wt p53) and NCI-H1299 (null p53) lung cancer cells were used and cell viability test was done by MTT assay. Apoptosis was confirmed with Annexin V assay followed by FACS analysis. To study $NF-{\kappa}B$-dependent transcriptional activation, a luciferase reporter gene assay was used after making A549 and NCI-H1299 cells stably transfected with IgG ${\kappa}-NF-{\kappa}B$ luciferase construct. To investigate DNA binding of $NF-{\kappa}B$ activated by TRAIL, electromobility shift assay was used and supershift assay was done using anti-p65 antibody. Western blot was done for the study of $I{\kappa}B{\alpha}$ degradation. Results: A549 and NCI-H1299 cells were relatively resistant to TRAIL-induced apoptosis showing only 20~30% cell death even at the concentration 100 ng/ml, but MG132 ($3{\mu}M$) pre-treatment 1 hour prior to TRAIL addition greatly increased cell death more than 80%. Luciferase assay showed TRAIL-induced $NF-{\kappa}B$ transcriptional activity in both cell lines. Electromobility shift assay demonstrated DNA binding complex of $NF-{\kappa}B$ activated by TRAIL and supershift with p65 antibody. $I{\kappa}B{\alpha}$ degradation was proven by western blot. MG132 completely blocked both TRAIL-induced $NF-{\kappa}B$ dependent luciferase activity and DNA binding of $NF-{\kappa}B$. Conclusion: This results suggest that inhibition of $NF-{\kappa}B$ can be a potentially useful strategy to enhance TRAIL-induced tumor cell killing in lung cancer.

  • This study was performed to evaluate the anti-oxidative, anti-inflammatory, anti-allergy, and whitening effects of Zizania latifolia ethanol extracts prepared from 5 different ethanol concentrations (10, 30, 50, 70, and 90%). As the ethanol concentration in the extraction solvent was increased, the radical scavenging activities also increased. The inhibitory activity of Z. latifolia ethanol extracts on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells tended to increase as the content of ethanol increased. The highest inhibitory activity was obtained with 70% ethanol extract. The antiallergy effects of Z. latifolia ethanol extracts were tested by measuring the release of ${\beta}-hexosaminidase$ in IgE-sensitized RBL-2H3 cells. The suppressive effect of Z. latifolia ethanol extracts increased in a dose-dependent manner as the proportion of ethanol increased, except for the 10% ethanol extract. Furthermore, the inhibitory effects of Z. latifolia ethanol extracts against melanin production in ${\alpha}-melanocyte$ stimulated hormone (MSH)-stimulated B16F0 cells increased as the ethanol ratio increased, and 70 and 90% ethanol extracts showed similar inhibitory activities to arbutin, a positive control, at $250{\mu}m$. The present study confirmed the efficacy of Z. latifolia ethanol extracts in various areas, demonstrating antioxidative, anti-inflammation, antiallergy, skin protective, and skin whitening effects, with no cytotoxicity. It could be used as a raw material in functional foods, as well as in cosmetics.
