The present study was conducted with the aim to investigate the ameliorative effects of a new soybean product (cheonggukjang) fermented with Bacillus amyloliquefaciens SCGB1 (SFBA) in atopic dermatitis (AD) mouse model. Visual evaluation of AD induction in the mice indicated the remarkable control of SFBA in reducing the pathological severity of AD-like skin lesions reported as the SCORAD score of AD clinical symptoms. The results revealed that SFBA reduced dorsal skin and epidermal thickness to a similar extent with prednisolone. Further analysis revealed the dominance of SFBA in restraining mast cell infiltration in the dermis; immunoglobulin-E expression in serum; and TH2 IL-4 cytokine and itch-related IL-31 cytokine in the mice skin and serum. SFBA also suppressed scratching behaviours in mice induced by compound 48/80. Further histological findings also revealed the alleviation of collagen fiber deposition in dermal skin of the AD mice model. These actions of SFBA were examined to be mediated by its suppression of the phosphorylation activation of key signalling molecules such as $NF-{\kappa}B$ and MAPK responsible for the induction of cytokine production. Thus, SFBA can be considered as a promising functional food for managing clinical, histological and immunological spectra associated with AD.

Objectives : The aim of this study is to investigate anti-atopic dermatitis effect using ato-tang.Methods : Ato-tang was external treatment to NC/Nga mice for 4 weeks, where atopic dermatitis was induced by DNCB at 1% and 0.4% for 3 weeks. Atopic dermatitis index score was measured using eye observation and picture evaluation. The histopathological change of dorsal skin was observed by hematoxylin and eosin (H&E) staining. Cytokines including IL-4, IL-5 and IL-13 were measured by Luminex or reverse transcriptase polymerase chain reaction (RT-PCR) analysis and immunoglobulin E (IgE) was measured by ELISA reader.Results : The dorsal skin of Ato-tang group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. Immunoglobulin cell infiltration and the thickness of epidermis were significantly decreased in the dorsal skin compared to control. Production of Th2 cytokines (IL-4, IL-5, IL-13) and IgE level in serum were all significantly decreased, in comparison with control. In addition, mRNA expression level of Th2 cytokines (IL-4, IL-5, IL-13) in spleen was decreased, in comparison with control.Conclusion : The results indicated that external treatment of ato was improved skin barrier function in the symptoms of atopic dermatitis disease. Also, atopic dermatitis factors where cytokine as well as immunoglobulin E in serum and mRNA expression were decreased, respectively, in comparison with control. Therefore, we suggest that ato could be effectively used as a external therapeutic drug based on atopic dermatitis factors.

Objectives Hataedock is an orally-administered herbal extract that used to treat toxic heat and help excrete meconium accumulates in the fetus from pregnancy. This study compared the effects of Hataedock using the extract of Douchi and omega-3 to control inflammation in the colonic mucosa. Methods NC/Nga mice were divided into three groups; Control group (no treatment), FGT group (given the extract of Douchi), and O3T group (given omega-3). The 3-week-old mouse from each group were given the extract of Douchi and omega-3. After 2 weeks, the colonic mucosa tissues of the mice were observed via Immunohistochemical staining for IL-4, IL-13, CD40, $Fc{\varepsilon}RI$, $p-I{\kappa}B$, EGF in the intestinal mucosa. Results In both FGT and O3T group, IL-4, IL-13, STAT-6 levels and CD40-positive reactions were decreased. However, EGF-positive responses were increased. FGT group showed 35% decrease in IL-4, 45% decrease in IL-13, 48% decrease in CD40, 50% decrease in $Fc{\varepsilon}RI$, 54% decrease in $p-I{\kappa}B$, 52% increase in EGF compared to the control group. O3T group also showed 14% decrease in IL-4, 23% decrease in IL-13, 22% decrease in CD40, 29% decrease in $Fc{\varepsilon}RI$, 41% decrease in $p-I{\kappa}B$, 39% increase in EGF compared to the control group. Conclusions Both early administration of Douchi extract and omega-3 were effective in regulating Th2, relieving inflammation and developing colonic mucosal tissues. Hataedock with Douchi extract may be more effective in modulating immune system in colonic mucosa than omega-3.

Background: Gastritis and gastric cancer are the most common diseases in the Kazakh population. Polymorphisms in genes coding of cytokines have been played important role with gastric disease risk. The risk alleles of cytokines in patients with gastritis can predict the risk of developing gastric cancer. The aim of this study was to investigate cytokine gene polymorphisms as risk factors for the development of gastritis in a case-control study with gastritis patients and healthy individuals from the Kazakh ethnic group, living in North Kazakhstan. Materials and Methods: The polymerase chain reaction followed by direct sequencing were used for detection of two functional polymorphisms in the IL1 gene family, and TaqMan SNP Genotyping Assay Sets were applied for three potentially functional polymorphisms in the IL10 gene, and one in the TNFA promoter. Results: Association analysis of studied allelic variants and the development of gastritis in H. pylori-positive patients showed that IL1B -31C/C, IL1B -511T/T and IL1RN -2/2 allelic variants were associated with development of gastritis (OR=1.8 (1.07-3.16), p=0.025; OR=1.7 (1.04-2.99), p=0.035, and OR=4.92 (2.45-9.85), p<0.001) respectively. Haplotype C-Т that combines both homozygous allelic variants of IL1B gene also had a statistically significant association with slightly higher OR (OR: 1.43, 95% CI: 1.08-1.88). Conclusions: The data from the current study showed that the genotype IL-1B -511Т/-31C-IL1-RN-2 and H. pylori infection increase risk of gastritis in the Kazakh population. That genotype combination might be a factor increasing the risk of developing gastric cancer.
