The purpose of this study was to investigate the dietary behaviors, eating habits, and nutrient intakes of elementary students with atopic dermatitis. Dietary conditions during infancy, dietary regularity, dietary behaviors, eating habits, and daily nutrient intakes were surveyed and compared between children with (WAD) and without (WOAD) atopic dermatitis using the 24-hr recall method. The ratio of children who responded 'I eat regular meals' was significantly lower in the WAD compared to WOAD group (76.4% vs. 81.7%, p<0.05). The ratio of children who answered 'I eat processed foods or fast foods more than once a week' (p<0.01) and 'I take nutritional supplements' (p<0.001) was significantly higher in the WAD compared to WOAD group. The scores for 'I eat milk and its products everyday' (1.4 vs. 1.5, p<0.05), 'I eat dishes fried or stirred with oil more than twice a week' (2.0 vs. 2.1, p<0.05), and 'I eat snacks such as ice cream, cake, snacks, carbonated beverages more than twice a week' (1.9 vs. 2.0, p<0.05) were significantly lower in the WAD group than in the WOAD group. Daily energy intakes were 1,859.1 kcal and 1,829.5 kcal in WAD and WOAD children, respectively, with no significant difference. However, daily intakes of fat (p<0.05), phosphorus (p<0.05), and vitamin $B_2$ (p<0.05) in WAD children were significantly higher than in WOAD children. To sum up, elementary students with atopic dermatitis had irregular eating habits and higher intake frequency of processed or fast foods, milk and its products, dishes fried or stirred with oil, and snacks compared to normal children. Dietary guidance and nutritional education are required to improve irregular eating habits and induce adequate nutrient intakes in children with atopic dermatitis.

Objective : The objective of this study was to demonstrate the effect of Persicae Semen (PS) in DNCB-induced atopic dermatitis mouse and HaCaT cell. Methods : The BALB/c mice were divided into four groups. To develop atopic dermatitis, 200 ㎕ of 1 and 0.5% DNCB solution was put on the back of mice in the Control group, the PS-Low group and the PS-High group once a day. After application of DNCB, 200 ㎕ of the PS extract was also treated. The Normal group was given PBS. The mice dorsal skin was stained with Masson's trichrome, H&E, and toluidine blue to evaluate the thickness of the epidermis and dermis, infiltration of eosinophils and mast cells respectively. ELISA was applied to measure the serum level of IgE and IL-6. Toxicity of PS was measured by MTS assay in HaCaT cell. To investigate the effects of PS on HaCaT cells, cells were pre-treated with PS for 1h, and then stimulated with TNF-α and IFN-γ. After 24 hours, the expression of TARC was analyzed using RT-PCR. Results : PS not only significantly diminished the thickness of the epidermis and dermis, but also reduced the infiltration of eosinophil and mast cell in skin lesion. PS also reduced the serum IgE and IL-6 level which plated important roles in the atopic dermatitis. The expression of TARC was decreased significantly in TNF-α/IFN-γ stimulated HaCaT cell. Conclusion : These results suggest that PS may be effective in alleviating the atopic dermatitis induced by DNCB and inflammation by TNF-α/IFN-γ.

Wished to examine closely effect that SoPungDoJeokTang-KaMi (SPDJTK) medicines used to atopy dermatitis disease patient get in atopy eruption control experimentally. SPDJTK medicines controlled $CD4^+/IFN-\gamma$, and $CD4^+/CD25^+/foxp3^+$ revelation that an experiment that motive allergy immune reponse because an in vitro experiment stimulates T cells of a NC/Nga mouse same time by anti-CD40/rmIL-4, and interleukin-$1{\beta}$, IL-6, TNF-$\alpha$, and TGF-$\beta$ mRNA outturn that bear in T and B cells decreased remarkably by SPDJTK medicines. Intracellular staining of splenocytes anti-CD40/rmIL-4 plus rmIL-4 stimulated as described in a, assessed after 24 h, SPDJTK exerts a mainly immunosuppressive effect that acts at least partially through suppression of the transcription factor GATA3 expression in $CD4^+$ T cells. Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen specially in childhood, association with IgE hyperproduction and precipitation by environmental factors. However, the exact etiology of AD has been unclear. To further explore the pathogenesis and treatment of AD, a suitable animal model is required. We found that skin lesions, which were clinically and histologically very similar to human AD, mite antigen-induced dermatitis on the face, neck, ears and dorsal skin of inbred NC/Nga mice. Result that Th1 cell and Th2 cell observe to be shifted by cytokine expression with $CD4^+/CD25^+/foxp3^+$ Treg cells induction by SPDJTK medicines could know that SPDJTK medicines can use usefully in allergy autoimmnune diease.

To evaluate the therapeutic effects of BGG on atopic dermatitis, we investigated the composition of immune cells of lymph node, PBMC and skin of Dermatophagoides farinae-induced NC/Nga mice. The levels of immunoglobulins in serum were analyzed at the protein level and the amount of pathologic cytokines were investigated using CD3/CD28 stimulated splenocytes. The results are summarized below; 1. BGG showed no cytotoxic effect up to $200\;{\mu}g/m{\ell}$ on mLFC in vitro. 2. BGG showed no hepatotoxicity in vivo based on the levels of ALT and AST. 3. Atopic dermatitis was improved through naked eye examination. BGG reduced the skin clinical index from 2.9 to 1.3 (p<0.01). 4. H&E and toluidine blue staining of tissue biopsies revealed that BGG inhibited the infiltration of lymphocytes and mast cells to skin. 5. BGG reduced the number of CD19 positive B cells in PBMCs by 16% (p<0.01), whereas cells were increased by 26% (p<0.05) in lymph nodes. 6. BGG reduced the numbers of B220+/CD23+ cells by 15% (p<0.01) and 33% in PBMCs and lymph node, respectively. 7. BGG reduced the numbers of B220+/IgE+ cells in PBMCs and lymph node by 21% and 33% (p<0.01), respectively. 8. BGG suppressed the levels of IgE (13%, p<0.001) as well as IgM (34%, p<0.001), IgG2a (40%, p<0.001) and IgG2b (26%, p<0.05). 9. BGG reduced the levels of IL-4 and IFN-$\gamma$ by 7% (p<0.05) and 13% (p<0.001) in anti-CD3 and anti-CD28-activated splenocytes, respectively. 10. BGG considerably inhibited the production of TNF-$\alpha$ and IL-6 by 42% (p<0.01) and 15% in the serum, respectively. Based on the results above, we concluded that BGG has therapeutic effects on atopic dermatitis by regulating the differentiation of B cells and isotype switching of IgE. Further investigations on the molecular mechanisms of BGG on atopic dermatitis are anticipated.

Atopic dermatitis is a chronic inflammatory skin disease characterized by pruritic and erythromatous skin lesions. In this study we examined the suppressive effects of SJJY on der f induced atopic dermatitis in NC/Nga mic, and concluded as follows: Oral administration of SJJY significantly decreased the severity score in the skin lesions at the dosage of 6.6 mg/25g/day for 8 weeks. SJJY significantly suppressed the infiltration of inflammatory cells into skin compared with control, and decreased the expression of CD4, CD8, CD20 and CCR3 in the skin lesions. SJJY significantly decreased the level of IgE in the serum compared with control, and the levels of IgM, IgG2a and IgG2b were also decreased. SJJY significantly decreased the levels of IL-6, but not TNF-a, in the serum compared with control. The levels of IFN-$\gamma$ was significantly increased in the supernatant of CD3/CD28 activated cultured splenocytes from the SJJY treated mice. The levels of IL-4 and IFN-$\gamma$ in the supernatants was much less in the der f activated splenocytes from SJJY treated mice than control. SJJY significantly increased the total number of cells in lymph node, while decreased the total number of skin compared with control. SJJY increased the number of CD3+ and CD4+ cell compared with control, while decreased the number of CD4+/CD25+ and CCR3+ cells in the PBMC. SJJY increased the number of CD3+, CD4+, CD8+, CD4+/CD25+, NKT+, CD3+/CD69+ cells compared with control, while decreased the number of B220+/IgE+, B220+/CD23+ cells in the lymph node. SJJY significantly decreased the number of CD3+/CD69+, CCR3+, B220+/IgE+, CD11b+/Gr-1+ compared with control in the skin lesions. Taken together, these results suggested that SJJY has suppressive effects on atopic dermatitis by the regulation of immune system and has potential as a therapeutics for atopic dermatitis. Further studies on molecular mechanisms on immune regulation are needed.

Ceramides, a constituent of stratum corneum lipids, play a crucial role in the formation and maintenance of the epidermal permeability barrier. As in many other skin disorders, atopic dermatitis and psoriasis show decrease and transformation of the ceramides. The application of ceramide has been demonstrated to be efficient in the repair of these skin disorders. Nevertheless, natural ceramides are still too expensive and small in quantity to be used as a cosmetic ingredient. Although a lot of pseudo-ceramides have been developed and on the market until now, those pseudo-ceramides did not fully meet the consumer's needs, therefore, there is still a demand for a novel pseudo-ceramides. We synthesized a novel pseudo-ceramide BPC-16 from 2-(2-amino-ethylamino)-ethanol(AEEA), which was characterized by structures having both amide bonds and hydroxyl groups as hydrophilic units, as well as two long alkyl chains. We formulated emulsion with BPC-16, cholesterol, stearic acid, and other components to make an emulsion. These emulsion showed a typical optical anisotropy on cross-polarized microscopy. This 'Maltese cross' appearance is a characteristic figure observed in concentric lamellar emulsion under cross-polarized microscopy. In cytotoxicity assay using MTT in monolayer and three dimension(3D) cell culture, a BPC-16 showed only negligible cytotoxicity up to the effective concentration for barrier repair and moisturization(less than 10 mM). In the measurement of TEWL, this BPC-16 showed significant recovery of water-retaining properties when it was topically applied to either SDS-induced dry skin or normal skin compared to that of base cream. This novel pseudo-ceramide BPC-16 showed as effective in skin barrier repair and moisturization as natural ceramides.

In the past decade there has been increasing concern about the atopic dermatitis (AD) associated with environmental diseases. AD has been increased in the last decade and known as one of the multifactoral diseases, which has the genetic background and environmental factors at the same time. The purposes of this study were to investigate the prevalence rate and etiologic risk factors of atopic dermatitis in preschool children in Changwon, which is a one of the Korean cities and has a large industrial complex. We reviewed and analyzed the statistical data, obtained from Korea National Health Insurance Corporation, related to prevalence rate by age and administrative district. A cross-sectional questionnaire survey, based on ISAAC (International Study of Allergy and Asthma in Childhood), was conducted on random samples of preschool children (5 to 8 years old) of large sized kindergartens in Changwon. The lifetime and last one years prevalence of AD in preschool children in Changwon was increased from 1998 to 2008. The prevalence rate of AD in the preschool children in Changwon city was 9.6%. The prevalence rate in boys was 9.7% and that in girls was 9.4%. The one year prevalence of AD was ranked as middle among other provincial cities in Korea in 2008. This study showed that the prevalence rate of the atopic disease in Changwon was 9% in 2008, which was increased especially compare to 2000. More active governmental approaches for control and prevention of atopic dermatitis for children are recommended. Further studies are needed for more accurate estimation of the prevalence of AD in Korea including different regional and age population.
