  • The purpose of this study is to examine the effect of herbal medicine complex (HMC) containing Camellia sinensis L., Duchoesna chrysantha, Houttuynia cordata Thunberg, Poncirus trifoliata Rafinesque on skin inflammation and atopic dermatitis. First, we examined the anti-inflammatory effect of HMC in TNF-α induced human keratinocytes (HaCaT cell). Real-time PCR and western blotting were performed to evaluate the expression of inflammatory cytokines (e.g., iNOS, COX-2, IL-6, IL-8) mRNA and protein. Four-weeks old male NC/Nga mice were treated with 1% 2,4-dinitrochlorobenzene (DNCB) solution and used as an atopic dermatitis mice model. And, HMC (200 mg/kg or 400 mg/kg) was administered directly into the stomach of mice for 4 weeks, and blood or serum analysis, tissue staining were performed after oral gavage. As a result HMC inhibited the mRNA expression of iNOS, COX-2, IL-6, and IL-8, which had been increased by TNF-α in HaCaT cells. In addition, the protein expression was also significantly suppressed in the same way as the mRNA expression results. The in vivo experiment results showed that, HMC administration reduced thickening of the epidermis and infiltration of eosinophil into the skin stratum basale compared to DNCB treatment. In addition, HMC administration significantly reduced the inflammatory cytokines (IL-4, IL-5, IL-6, and IL-13) production and immunocyte (white blood cell, lymphocyte, neutrophil, and eosinophil) count compared to DNCB treatment. Moreover, the serum IgE and histamine level was decreased by HMC administration. These results suggest that HMC can be used as effective herbal medicine extract for skin inflammation and atopic dermatitis. And this study may contribute to the development of the herbal medicine-based drug for the treatment of skin inflammation and atopic dermatitis.

  • Objectives : Atopic dermatitis is a chronic inflammatory skin disease with frequent relapses. This study was to investigate the effects of Gammakdaejo-tang(GMD) in DNCB induced atopic dermatitis mice. Methods : The study was divided into five comparion groups. 2,4-dinitrochlorobenzene(DNCB) solution was applied to Nc/Nga mice to induce atopic dermatitis, followed by normal group, negative control group with distilled water, positive control group with Dexamethasione and GMD 200mg/kg or 400mg/kg. The control group was orally administered 200㎕ once daily for 4 weeks. Visual skin condition, Immunoglobulin E, Histamine, Cytokine, Immune cells, Tissue biomarkers were observed. Results : As a result of the dermatitis score evaluation, it was confirmed that the GMD-administered group improved symptoms compared to the negative control group. As a result of measuring IgE, the GMD-administered group significantly decreased compared to the negative control group. As a result of measuring Histamine, GMD group except 200mg/kg of GMD significantly decreased compared to negative control group. As a result of measuring cytokine, GMD 200mg/kg significantly reduced IL-1β, IL-6 and TNF-α compared to the negative control. 400mg/kg significantly reduced IL-1β, IL-4, IL-5, IL-6, IL-10, TNF-α and significantly increased IL-2, IFNγ. As a result of confirming the immune cells, all experimental groups showed no difference in basophil, GMD group significantly reduced monocyte and eosinophil compared to negative control group, and GMD 400mg/kg group significantly reduced white blood cell and neutrophil. And significantly increased lymphocytes. As a result of measuring the gene expression level, all GMD group significantly increased TGF-β1 compared with the negative control group, and filaggrin, VEGF and EGF were significantly increased in GMD 400mg/kg group. Epidermis, dermis thickness, and eosinophil infiltration were found to be decreased in all GMD groups compared with the negative control group. Conclusions : GMD is effective in atopic dermatitis by reducing imbalance of immune response of T cells (Th1 / Th2) and reducing skin tissue damage and inflammatory response.

  • Although the parallel prescription of Sopoongsangagambang (SG) administration along with external treatment such as spraying or ointment application on the skin is clinically used for the treatment of atopic dermatitis (AD), molecular mechanism underlying its effectiveness is unknown. Thus in the present study, diverse immune responses in terms of chemical mediators related to AD were investigated using an atopic mouse model NC/Nga after SG administration and external treatment (ET), and major findings are summarized as follows. 1. The clinical severities in 16 and 20 week old NC/Nga mice with SG and ET treatment were decreased to 72.2% and 62.3% respectively compared to the control NC/Nga mice with no drug treatment. 2. IgE, IL-4, IL-5, IL-6, IL-13, IgM, IgG1 and IgG2a levels in the serum of SG and ET treated NC/Nga mouse group were significantly decreased compared to the untreated control mice. In contrast, $IFN-{\gamma}$ showed a significant increase in the experimental group compared to the untreated control group. 3. The spleen weight of SG and ET treated NC/Nga mice was significantly decreased compared to the untreated control group. 4. The B/T ratio in the lymph node of SG and ET treated NC/Nga mice was increased compared to the untreated control group. $CD4^+\;and\;CD8^+$ cell numbers in the lymph node of SG and ET treated NC/Nga mice were significantly increased compared to the untreated control group, but $CD69^+\;and\;CD11a^+$ cells were significantly decreased. 5. mRNA expression levels of IL-4, IL-5, and CCR3 in the skin tissues of SG and ET treated NC/Nga mice were significantly decreased, and expression levels of IL-6, IL-13, $CD69^+/CD3{\varepsilon}^+\;and\;CD19^+/CD44^+$ in the skin tissues of SG and ET treated NC/Mga mice were significantly decreased compared to the untreated control group. $IFN-{\gamma}$ mRNA expression levels were increased compared to the untreated control group. 6. Histological observation of the ear and neck skin tissues showed that the extents of inflammation and infiltrated immune cells in the epidermis and dermis of SG and ET treated NC/Nga mice were highly reduced compared to the untreated control group. 7. Lymphokine assay showed a significant decrease in IL-4 levels in SG and ET treated NC/Nga mice compared to the untreated control group, but the levels of $IFN-{\gamma}$ secretion were significantly increased drug treated NC/Nga mice.

  • Botulinum neurotoxin A (BoNT/A) has been used therapeutically to treat muscular hypercontractions and sudomotor hyperactivity and it has been reported that BoNT/A might have analgesic properties in headache. PEP-1 peptide is a known carrier peptide that delivers fulll-ength native proteins in vitro and in vivo. In this study, a BoNT/A gene were fused with PEP-1 peptide in a bacterial expression vector to produce a genetic in-frame PEP-1-BoNT/A fusion protein. The expressed and purified PEP-1-BoNT/A fusion proteins were efficiently transduced into cells in a time- and dose-dependent manner when added exogenously in a culture medium. In addition, immuno-histochemical analysis revealed that PEP-1-BoNT/A fusion protein efficiently penetrated into the epidermis as well as the dermis of the subcutaneous layer, when sprayed on mice skin. These results suggest that PEP-1-BoNT/A fusion protein provide an efficient strategy for therapeutic delivery in various human diseases related to this protein.

  • In order to improve efficacy of oriental medicines and to study the application of fermented oriental medicine in clinicals, the efficacy of CYT and CYTBH on atopic dermatitis were evaluated. The results and conclusions are as follows. CYT and CYTBH significantly improved the atopic dermatitis symptoms in NC/Nga mice by naked eye evaluation and significantly decreased clinical index in both groups. CYT and CYTBH both decreased the cell numbers of CD3+, CD11b+Gr-1+ cells in dorsal skin. Of the cells, CYT significantly decreased CD11b+Gr-1+ cells whereas CYTBH significantly decreased all immune cells. CYT and CYTBH both decreased the production rate of IL-4 and IFN-${\gamma}$ activated by CD3/CD28. In the case of CYTBH, significant decrease in all cases was observed. CYT and CYTBH decreased the production rate of IL-5, IL-13 and IL-17 in serum. Significant decrease of IL-5 in the case of CYT and IL-5 and IL-13 in the case of CYTBH were observed. CYT and CYTBH significantly decreased transcription of IL-5 mRNA and IL-13 mRNA in skin. Significant decrease in IgG1 and IgE immunoglobulins in serum were oberved in both groups. Significant decrease was only observed in the case of CYTBH. Both CYT and CYTBH significantly decreased the secretion of histamine. Both CYT and CYTBH suppressed erythema, hemorrhage, edema, excoriation, erosion of skin tissues of NC/Nga mice resulting in the decrease of thickness of epidermis. Significant decrease of infiltration of obese cells was also observed. The results above indicated that both CYT and CYTBH had significant efficacy in the treatment of atopic dermatitis through immune modulation. Animal studies showed that CYTBH had superior activity than that of CYT suggesting further and continuous studies on the changes in ingredients or absorption improvement by fermentation should follow.
