  • Until recently, photogrammetric applications for processing the satellite images and remotely sensed data have been used in different structure of functions and interfaces for sensor modeling by each developer. Thus, a standardized utilization procedure was necessary to solve the problems, such as expandability, cost, inefficiency of sources which were resulted from different approaches. Therefore, National Geospatial Intelligence Agency (NGA) provided unified interfaces by developing Community Sensor Model (CSM) to sensor models in same way. In this study, we suggested the method of design and analyzed main functions needed modeling for the frame sensor using CSM Application Program Interface (API) provided by NGA. We also applied the designed structure to the modeling. The implemented CSM was verified by groundToImage and imageToGround. In the future, the active R&D is expected with using CSM due to the cost saving effect of software development and remarkable expandability of sensor.

  • We investigated the inhibitory effect of an oral administration of a Sophora flavescens Aiton ethanol extract (SFE) on the development of atopic dermatitis (AD) by using NC/Nga model mice. The induction of atopic dermatitis-like lesion was conducted by the removal of the back hairs and topical application of a mite antigen (Dermatophagoides farinae, Df) on to the back skin twice a week for 8 weeks. SFE was orally administered at a different doses (100-400 mg/kg). Atopic dermatitis-like skin lesions were evaluated by dermatitis scores, skin histology and immunological parameters (serum levels of IgE, TARC/CCL17, MDC/CCL22, and CTACK/CCL27). Oral administration of SFE significantly inhibited the clinical sign of Df-induced atopic dermatitis, including dermatitis score and leukocyte infiltration. Moreover, SFE suppressed significantly the serum IgE and Th2 chemokine (TARC/CCL17, MDC/CCL22, and CTACK/CCL27) levels in a concentration dependent manner. These results suggest that oral administration of SFE could reduce significantly the clinical signs and Th2 chemokines in Df-induced atopic dermatitis model mice. Therefore, SFE may be effective substances for the management of AD in human.

  • Objectives : The aim of this study is to investigate the effect of natural carbonated hot spring water (NCHW) on DNCB-induced NC/Nga mice, an atopic dermatitis (AD) model. Methods :At first, NC/Nga mice were prepared and induced to have atopic lesion on their back skin by dinitrochlorobenzene (DNCB). They swam for 20 minutes everyday in tanks where the one is filled with $28^{\circ}C$ NCHW, the other is with $25^{\circ}C$ carbonated hot spring water and another is with artificial carbonated hot spring water (ACHW). After 3 weeks, We assessed the skin clinical score and macroscopic appearance, total IgE, IgG1 levels, WBC differential counting, IFN-${\gamma}$, IL-4, IL-13, TNF-${\alpha}$ production levels and histological changes. Results : There are meaningful results of improving atopic lesion-state by relieving the count of total IgE, IgG1 levels, WBC differential counting, IFN-${\gamma}$, IL-4, IL-13, TNF-${\alpha}$ production levels and recovering skin clinical score in the group with $28^{\circ}C$ NCHW in comparison with the other groups. Conclusions : The NCHW may have potential as an effective treatment for atopic dermatitis.

  • Herbal medicine has a high body absorption rate when it ferments. Biological and clinical research on the fermented herb gradually increases because it has effective materials for the treatment of a disease and it is a little bitter. In this study, we investigated the effect of fermented Baedokhwanbalhyobang (BDHBH) on attenuation of the development of atopic dermatitis in NC/Nga mice by evaluating the cytokine level in serum, the mRNA expression of cytokine and histological alteration of the skin, and the skin severity. We have come to the following conclusion. BDHBH led to a significant decrease in the skin severity score (63.1%) as compared to the control group. CD4+/CD45+, CD4+, B220+/CD23+, and CD11b+/Gr-1+cells of peripheral mononuclear cells (PBMCs) in the BDHBH-treated group were decreased to 6.7%, 31.1%, 22.4%, 36.6%, respectively. CD3+and CD11b+/Gr-1+immune cells in dorsal skin of the BDHBH-treated group were decreased to 52.9% and 28.0%. The levels of IL-5 and IL-13 in serum of the BDHBH-treated group were inhibited to 18.8% and 5.1%. The mRNA expressions of IL-5 and IL-13 in dorsal skin were also decreased to 30.6% and 27.8% after the treatment of BDHBH. BDHBH inhibited the proliferation and differentiation of eosinophils. In histological examination, BDHBH decreased the thickness of epidermis and dermis, and infilatration of mast cells as compared to the control group. These results indicate that BDHBH inhibits the pathogenic development of atopic dermatitis in NC/Nga mice. These results may indicate that BDHBH attenuates the development of atopic dermatitis-like lesions by lowering immune cells and inflammatory cytokine levels, and that it is valuable in drug development for the treatment of atopic dermatitis. Further experiments on the components of BDHBH will be needed to better understand the effect of a fermented herb as compared to a herb.

  • Objectives: Galgeun-tang (GGT, gegen-tang, kakkon-to), an herbal formula, is used to treat the common cold, fevers, headaches, hangovers and neck and upper back stiffness. The drugs currently used to treat atopic dermatitis (AD) are limited by the significant adverse effects associated with their long-term usage. The need to efficiently manage the AD response while reducing side effects has led to the development of alternative remedies. Methods: To assess the effects of GGT on AD, the anti-inflammatory and anti-AD properties of GGT were evaluated in both in vitro and in vivo systems. Results: Nitric oxide (NO) and histamine production on lipopolysaccharide (LPS)-treated RAW264.7 cells and phorbol-12 myristate 13-acetate (PMA)/A23187-treated MC/9 cells, respectively, were inhibited by GGT. GGT reduced thymus and activation-regulated chemokine (TARC/CCL17) release on TNF-${\alpha}$/IFN-${\gamma}$ stimulated HaCaT cells in a dose-dependent manner. GGT reduced both plasma levels of IgE and histamine and the dermatitis score in house dust mite induced atopic dermatitis-like lesions on NC/Nga mice. However, there were no significant histopathological differences observed between the GGT group and the AD-induced group, such as AD-like lesions in the dorsal skin or ear or mast cell infiltration in the dorsal skin. Conclusions: These results indicate that GGT inhibits chemokine production by keratinocytes and the atopic dermatitis response in NC/Nga mice, suggesting that GGT may be useful as a therapeutic remedy for treating AD and allergic inflammation-related diseases.

  • Objectives Hataedock is a Korean herbal medical oral treatment that removes fetal toxic heat and meconium from new born babies. The purpose of this study is to evaluate whether Hataedock treatment of Duchi extracts has anti-inflammation effects on AD (Atopic Dermatitis)-induced NC/Nga mice. Methods After Hataedock treatment of Duchi extracts on days 0, 3-week-old NC/Nga mice were sensitized on days 28, 35, 42 by exposure of DNFB (dinitrochlorobenzene) and were induced to have AD. Immunohistochemistry of NF-${\kappa}B$ p65, iNOS, COX-2 and TUNEL assay of apoptotic body was used to identify changes of skin damages and anti-inflammation effects. Results The alleviate effect of the skin damage and angiogenesis was observed in DT group. The damage of stratum corneum, hyperplasia, edema, infiltration of lymphocytes and distribution of capillary were decreased in DT group. Also, the study results suggested that Hataedock treatment of Duchi extracts in DT group remarkably downregulated levels of NF-${\kappa}B$ p65 by 70% (p < 0.001), as well as COX-2 by 51%, iNOS by 62% (p < 0.001). Additionally, Hataedock treatment of Duchi extracts in DT group up-regulated apoptosis of inflammatory cells by 68% in atopic dermatitis-like skin lesion. Conclusions From the study results, we observed that Hataedock treatment of Duchi extracts alleviates AD through diminishing various inflammatory cytokines in the skin lesions, which are involved in the initial steps of AD development. It is anticipated to have potential applications for prevention and treatment of atopic dermatitis.

  • We examined the effects of essential oil from Thujopsis dolobrata Sieb. et Zucc. var. hondai Makino (EOTD) (Cupressaceae) on atopic dermatitis (AD)-like skin lesions in NC/Nga mice. Treatment with EOTD twice daily for two weeks ameliorate AD-like skin lesions induced by DNCB (2,4 dinitrochlorobenzene), and clinical scores were reduced to 7.29, 7.07, and 4.5 points in the groups treated with 1.5%, 3.0%, and 6.0% extract (p<0.01) respectively, from the 15.0 score obtained using vehicle. EOTD inhibited the infiltration of mast cells into the AD-like skin lesion in NC/Nga mice (p<0.01) and also reduced serum histamine and IgE levels (p<0.05). Furthermore, it dose-dependently inhibited the release of beta-hexosaminidase from rat basophilic leukemia RBL 2H3 cells. These results indicate that EOTD reduces AD-like skin lesions by inhibiting the production of IgE and histamine, and, thus, IgE-mediated degranulation.

  • Oxidative stress has been implicated in cutaneous damage in various inflammatory skin diseases, including atopic dermatitis (AD). Atoberry is the herb medicine extract which is composed with Spirodelae Herba, Xanthii Fructus, Houttuyniae Herba, Taraxaci Herba, Retinervus Luffae Fructus, Platycodi Radix, and Scutellariae Radix. In this study, we investigated the antioxidant and anti-inflammatory effects of Atoberry in AD-like skin lesion NC/Nga mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinse (Df) extract. Atoberry significantly increased electron donating ability (DPPH), nitrite scavenging (NO) and superoxide dismutase (SOD) activities in dose dependant. Topically applied Atoberry significantly reduced clinical severity score, ear thickness and histological grade in AD-like skin lesion NC/Nga mice. In addition, the serum levels of IgE, NO and prostaglandin E2 were significantly reduced by Atoberry. Futhermore, skin tissue levels of SOD, catalase and glutathione peroxidase (GPx) were significantly reduced by Atoberry. These results demonstrate that topical application of Atoberry may be improve the AD-like skin lesion by antioxidant and anti-inflammatory effects.

  • Atopic dermatitis (AD) is a chronically relapsing pruritic inflammatory skin disease. To find new anti-inflammatory products for skin inflammatory disease such as AD and contact dermatitis, we produced the effective microorganism fermentation substance (EM-S) by fermentation of medicinal plants with effective microorganisms including photosynthetic bacteria, lactic acid bacteria and yeast, screened the effects of EM-S on NC/Nga model mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinae (Df) extract. Topically applied EM-S significantly reduced clinical severity score, ear thickness and histological grade in AD-like NC/Nga mouse model by Df antigen sensitization. In addition, the serum IgE and Th2 chemokine levels (TARC/CCL17, MDC/CCL22 and CTACK/CCL27) were significantly reduced by EM-S. Futhermore, skin tissue expressions of Th2 chemokines were significantly reduced by EM-S. These results demonstrate that topical application of EM-S may be improve the AD-like skin lesion by suppressing IgE and Th2 chemokines.
