  • In order to investigate the efficacy of a combination of JBB as topical and HTGMB as internal treatment method, changes in various immune related factors and histological changes in NC/Nga induced animal model was studied. Combined treatment of topical JBB and internal HTGMB significantly reduced the atopic dermatitis clinical index, the number of immune cells such as CD19+, CCR3+, B220+/IgE+, and Gr-1+/CD11b+ in DLN and dorsal skin, compared to the control group. Otherwise increased CD3+, CD4+/CD25+, CD8+ and CD4+ cells in the DLN. And also combined treatment of topical JBB and internal HTGMB suppressed the lymphocytes and mast cells from infiltrating into the skin tissues when stained with H&E and toluidine blue. Based on the results above, it is strongly suggested that the combined treatment of topical JBB and internal HTGMB significantly induced anti-allergic activities through immune modulation. The findings can be applied to developing a more sustainable treatment for atopic dermatitis and be helpful in practicing combined treatments in clinical treatments in the future.

  • Objectives NJ is being used to treat inflammatory diseases in Korea. In this study, we attempted to evaluate the effects of NJ on atopic dermatitis (AD)-like lesions and mast cell-mediated allergy inflammation in vivo and in vitro. Methods and Results We investigated to ascertain the pharmacological effects of NJ on 2,4-dinitrofluorobenzene (DNFB)-induced allergic reactions under in vivo conditions. Additionally, to find possible explanations for the anti-inflammatory mechanisms of NJ, we evaluated the regulatory effects of NJ on the level of inflammatory mediators in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Conclusions NJ inhibited the production of the inflammatory cytokines (IgE, IL-6, IL-8 and TNF-${\alpha}$) significantly in vivo and in vitro.

  • Sopungsan (SS) is a traditional Korean decoction used for the treatment of dermatitis. The aim of this study is to confirm whether or not SS has a preventive effect on the development of atopic dermatitis in dinitrochlorobenzene-applied Nc/Nga mice. SS was administered orally to Nc/Nga mice, which led to the remarkable suppression of the development of dermatitis, as determined by a histological examination and the serum IgE levels. Moreover, SS inhibited the production of thymus- and activation-regulated chemokine (TARC) and its mRNA expression in a keratinocyte cell line, HaCaT, which had been stimulated with tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interferon-${\gamma}$ (IFN-${\gamma}$). Activation of the nuclear factor-${\kappa}B$ (NF-${\kappa}B$) or activator protein-1 (AP-1) is one of key steps in the signaling pathways mediating induction of TARC. In this study, SS selectively suppressed NF-${\kappa}B$ activation which may be essential for TARC expression in $TNF-{\alpha}/IFN-{\gamma}$ treated keratinocytes. The inhibitory effect of SS on NF-${\kappa}B$ activation and TARC production might be associated with the anti-dermatitic effects of SS.

  • In order to investigate the efficacy of HYGBH on atopic dermatitis, various immune related factors were studied. The results and conclusions are as follows. Atopic dermatitis symptoms were improved in HYGBH treated group and significant decrease in dermatitis index were observed in 12 and 14 weeks. HYGBH treated group showed significant decrease in CD4+, CD3+/CD69+ immune cell ratio in PBMC by 18% and 40.6% respectively. HYGBH treated group showed significant decrease in CD3+, CD11b+/Gr-1+ immune cell ratio in dorsal skin by 44.6% and 53.1% respectively. HYGBH treated group showed significant decrease in IL-4, IFN-${\gamma}$ in spleen by 29.5%, 7.7% respectively. HYGBH treated group showed decrease in the expression of IL-5, IL-13, IL-17 and histamine by 21%, 9.6%, 14%, and 32.2% respectively. Also the group showed decrease in the expression of IgE by 6.8% respectively. HYGBH treated group showed significant decrease in the transcription of IL-5 and IL-3 mRNA in skin by 35.5% and 23.2% respectively. The results above indicated that treatment of HYGBH improved atopic dermatitis symptoms by anti-oxidant activity as well as immune modulation activity as a clinical evidence. Also, to increase the application of fermented oriental medicine, different fermentation conditions using various microbial strains should be accumulated as the clinical evidence in the future.

  • Various related factors and tissue changes in vitro and in vivo were observed to investigate the efficacy of HYBH on atopic dermatitis. The results are described below. HYBH improved the atopic dermatitis symptoms by naked eye examination, and significantly decreased dermatitis clinical index at 14 weeks. HYBH significantly decreased CD4+/CD45+, CD4+, CD8+, CD3+/CD69+ immune cell ratios in PBMC by 28%, 16%, 30%, 26% and 22% respectively. HYBH significantly decreased CD11b+/Gr-1+, CD3 immune cell ratios in dorsal skin by 35.3% and 67.5% respectively. HYBH significantly decreased the expression of IL-4 and IFN-${\gamma}$ in spleen by 23% and 15% respectively. HYBH significantly decreased the production rate of IL-5, IL-13 and histamine in serum by 17%, 23%, and 8.8% respectively and increased IL-17 production by 17%. HYBH significantly decreased immunoglubulins IgG1 and IgE production in serum. The results above indicated that treatment of HYBH improved atopic dermatitis symptoms by anti-oxidant activity and immune modulation activity as a clinical evidence. Also, different fermentation conditions using various microbial strains should be accumulated as the clinical evidence for broad application in the future.

  • This study was conducted to find a candidate prescription with anti-inflammatory efficacy of 7 herbal prescriptions known to be effective in atopic dermatitis and sleep disorders in Korean medicine. The anti-inflammatory of the 7 herbal prescriptions extracts were evaluated by ELISA assay and Western blot assay. 7 herbal prescriptions, Seongyutang(SU), Danseontoetang(DST), Sotosajahwan(ST), Jisiljagyagsan(JJ), Seokchangpo(SCP), Wiryeongseon(WLS), Gogojohwan(GGJ) 30 % EtoH extract was used for in vitro experiments. In TNF-α + IFN-γ(TI) stimulated HaCaT cells, all 7 herbal prescriptions reduced TARC and MDC production, and JJ strongly reduced TARC and MDC production at 100 ㎍/ml concentration. SCP strongly reduced MDC production at 10 ㎍/ml and 100 ㎍/ml concentration. In addition, in substance P(SP)/CRH stimulated HMC-1 cells, JJ strongly inhibited VEGF production at both 10 and 100 ㎍/ml concentrations. In LPS/CRH stimulated Raw264.7 cells, all 7 herbal prescriptions significantly inhibited TNF-α. PMA + Ionomycin(PI)/CRH stimulated EL4 cells, SU significantly reduced IL-4 production at both concentrations of 10 and 100 ㎍/ml. WLS significantly reduced IL-17 production at both concentrations of 10 and 100㎍/ml. This suggests that 7 herbal prescriptions have anti-inflammatory effects by reducing inflammatory cytokines in keratinocytes, mast cells and macrophages caused by inflammation. Therefore, it is expected that 7 herbal prescriptions that are effective for sleep disorders and atopic dermatitis can be used as therapeutic materials for sleep disorders and diseases associated with atopic dermatitis.

  • Cordyceps bassiana is one of Cordyceps species with anti-oxidative, anti-cancer, anti-inflammatory, anti-diabetic, anti-obesity, anti-angiogenic, and anti-nociceptive activities. This mushroom has recently demonstrated to have an ability to reduce 2,4-dinitrofluorobenzene-induced atopic dermatitis symptoms in NC/Nga mice. In this study, we further examined phytochemical properties of this mushroom by column chromatography and HPLC analysis. By chromatographic separation and spectroscopic analysis, 8 compounds, such as 1,9-dimethylguanine (1), adenosine (2), uridine (3), nicotinamide (4), 3-methyluracil (5), 1,7-dimethylxanthine (6), nudifloric acid (7), and mannitol (8) were identified from 6 different fractions and 4 more subfractions. Through evaluation of their anti-inflammatory activities using reporter gene assay and mRNA analysis, compound 1 was found to block luciferase activity induced by $NF-{\kappa}B$ and AP-1, suppress the mRNA levels of cyclooxygenase (COX)-2 and tumor necrosis factor $(TNF)-{\alpha}$. Therefore, our data strongly suggests that compound 1 acts as one of major principles in Cordyceps bassiana with anti-inflammatory and anti-atopic dermatitis activities.

  • Atopic dermatitis (AD) is a chronic inflammatory skin disease accompanied by severe itching, mainly before five. The aim of this study is to investigate the effects of 405 nm+850 nm LED light therapy on AD-like symptoms in NC/Nga mice. The mice were randomly placed in the normal (Vehicle), atopic dermatitis-induced (CON), and 405 nm + 850 nm LED light therapy (LED) groups. The LED experimental group conducted 405 nm+850 nm wavelength LED ray therapy for 10 minutes a day for seven days. LED light therapy research confirmed the improvement and improvement of Dermatics score and observed the reduction of epidermal tissue thickness caused by dermatitis. Based on the significant decrease of serum IL-1𝛽 and transdermal moisture loss and serum IgE concentration due to LED light therapy, LED light therapy can help restore normal skin conditions in mice that cause atopic dermatitis. This study showed the anti-atopic effect of infrared light and blue light. Light in mice with atopic dermatitis led to the simultaneous use of circular LEDs with two wavelengths.

  • Activated T helper 2 (Th2) immune function is hallmark of various allergic diseases. We investigated the anti-allergic effect of Jagamcho-tang extract(JE) on ovalbumin(OVA)-induced atopic dermatitis mice model and OVA-stimulated splenocytes isolated from the mice. Mice were intraperitoneally injected OVA/alum solution 2 times at interval of 14 days, followed by oral administration of JE for 7 days. After administration, mice were subcutaneously injected with OVA in ear. JE treatment reduced ear swelling and infiltration of inflammatory cells in ear. Serum levels of interleukin(IL)-4 and immunoglobulins, such as total-IgE and OVA-specific IgE, were decreased in JE treated group. Furthermore, JE treatment decreased OVA-induced Th2-associated cytokines like IL-4, IL-5 and IL-13 mRNA levels in splenocytes. In conclusion, JE reduced allergic immune response via IgE production and Th2 response in OVA-sensitized mice, suggesting that JE could be useful prescription for allergic diseases including atopic dermatitis.
