  • Objective : This study was designed to identify lipid protection formation in stratum corneum and anti-inflammatory effects of Sopungdojeok-tang(SD) on atopic dermatitis(AD). Materials and Methods : In Vivo, SD extract was orally administered to BALB/c mice at $2.5m{\ell}/kg/day$ for 2 days after 5% sodium dodecyl sulfate evoked atopic dermatitis in abdominal skin. Morphological changes were observed by immunohistochemical stain using monoclonal antibodies(BrdU, ceramide, MIP-2, $NF-{\kappa}B$ p50, IL-4, and STAT6) and TUNEL method. In vitro, the alterations of IL-4 mRNA expression were detected by RT-PCT in SD extract treated EL4 cells after phorbol-12-myristate-13-acetate and 4-tert-Octylphenol induce Th2 skewed condition. Results : SD is used in Oriental Medicine for its potential curative for atopic dermatitis. In this study, we have investigated the anti-inflammatory and lipid lamella repair effects of SD were investigated. SD decreased the number of eosinophil in atopic dermatitis induced mice. In the histological properties, the hyperplasia, edema, infiltration of lymphocytes, damage of intercellular space of stratum corneum, BrdU positive reacted cells in stratum basal, and degranulated mast cells and capillaries in dermal papillae decreased in mice with SD. Treatment of SD also decreased MIP-2, STAT6 and IL-4 in dermal papillae. The IL-4 mRNA expression decreased in a dose-dependant manner in SD treated EL4 cells. In addition, decrease of $NF-{\kappa}B$ p50 and increase of apoptotic cells in dermis were observed in SD treated mice. These data suggest that SD may beneficial for atopic dermatitis. Conclusions : These data suggest that SD is beneficial in treatment of atopic dermatitis, and that SD provides lipid protection in stratum corneum and anti-inflammatory effects on atopic dermatitis.

  • Background: As a kind of common complication of the surgery of perianal diseases, perianal ulcer is known as a nuisance. This study aims to develop a kind of 20(S)-ginsenoside Rg3 (Rg3)-loaded hydrogel to treat perianal ulcers in a rat model. Methods: The copolymers PLGA1600-PEG1000-PLGA1600 were synthesized by ring-opening polymerization process and Rg3-loaded hydrogel was then developed. The perianal ulcer rat model was established to analyze the treatment efficacy of Rg3-loaded hydrogel for ulceration healing for 15 days. The animals were divided into control group, hydrogel group, free Rg3 group, Rg3-loaded hydrogel group, and Lidocaine Gel® group. The residual wound area rate was calculated and the blood concentrations of interleukin-1 (IL-1), interleukin-6 (IL-6), and vascular endothelial growth factor (VEGF) were recorded. Hematoxylin and eosin (H&E) staining, Masson's Trichrome (MT) staining, and tumor necrosis factor α (TNF-α), Ki-67, CD31, ERK1/2, and NF-κB immunohistochemical staining were performed. Results: The biodegradable and biocompatible hydrogel carries a homogenous interactive porous structure with 10 ㎛ pore size and five weeks in vivo degradation time. The loaded Rg3 can be released sustainably. The in vitro cytotoxicity study showed that the hydrogel had no effect on survival rate of murine skin fibroblasts L929. The Rg3-loaded hydrogel can facilitate perianal ulcer healing by inhibiting local and systematic inflammatory responses, swelling the proliferation of nuclear cells, collagen deposition, and vascularization, and activating ERK signal pathway. Conclusion: The Rg3-loaded hydrogel shows the best treatment efficacy of perianal ulcer and may be a candidate for perianal ulcer treatment.

  • The SKINTEX Method is based on a two-compartment physico-chemical model which includes a Biomembrane Barrier in compartment one and an organized macromolecular matrix in compartment two. Test samples absorb onto or permeate through the keratin/collagen Biomembrane Barrier and then can interact with the organized macromolecular matrix. Changes in the integrity of the barrier release a dye indicator: Changes in the matrix can alter its transparency. The sum of these two responses is read spectrophotometrically at 470nm. An early investigation of 950 chemicals and formulations in the SKINTEX System produced results which were 89% concordance to in vivo Draize dermal irritation results obtained with 24-hour occluded application of test samples with-out abrasion and standard scoring. Alkaline materials were analyzed in a specialized SKINTEX AMA Protocol. In this early study, the model did not distinguish nonirritant test materials and formulation with PDII(Primary Dermal Irritation Index)in the range from 0 to 1.2, A High Sensitivity Assay Protocol(HSA)was developed to amplify the changes in both compartments of this model and provide more accurate calibration of these changes. A study of 60 low irritation test samples including cosmetics, household products, chemicals and petro-chemicals distinguished nonirritants with PDII $\leq$ 0.7 for 26 of 30 nonirritants. A second protocol was developed to evaluate the SKINTEX model predictability with respect to human irritation. The Human Response Assay (HRA )has been optimized based on differences in penetration and irritation responses in humans and rabbits. An additional 32 test materials with different mechanisms and degrees of dermal toxicity were evaluated by the HRA. These in vitro results were 86% concordant to human patch test results. In order to further evaluate this model, a Standard Chemical Labelling (SCL) Protocol was developed to optimize this system to predict Draize dermal irritation results after a 4-hour application of the test material. In a study of 52 chemicals including acids, bases, solvents, salts, surfactants and preservatives, the SCL results demonstrated 85% concordance to Draize results for a 4-hour application of test samples on non-abraded rabbit skin. The SKINTEX System, including three specialized protocols, provided results which demonstrated good correlation to the endpoint of dermal irritation in man and rabbits at different application times.

  • 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.

  • Objectives : This study was performed to determine the transdermal effects of ethanol extract from medicinal herbal mixture (SHJ) on hair growth in C57BL/6 mice and melanogenesis in melanoma cells. Methods : Mice were divided into 3 experimental groups including vehicle (CON), SHJ extract and 5% minoxidil (MNXD, positive control)-treated group. SHJ was applied topically on the hair-shaved skin of C57BL/6 mice everyday for 15 days. The thickness and density of hair with a folliscope and morphometry of hair follicle with a H&E staining were monitored at last day. Also then, hair growth-associated gene expressions were measured by immunoblot assay. Results : The MNXD or SHJ-treated group promoted on hair growth compared to that of vehicle-treated group (CON). Hair density and thickness of MNXD or SHJ treated-group increased compared to that of vehicle application on the 15 days, respectively. Induction of insulin-like growth factor (IGF)-1 and vascular endothelial growth factor (VEGF) were also accelerated by application of SHJ extract compared to those of CON group. But expression of transforming growth factor (TGF)-${\beta}1$ decreased in SHJ treated-group compared to that of CON group. Furthermore, SHJ extract showed to increase melanin contents in a dose-dependent manner. Tyrosinase activity significantly increased in SHJ-treated group compared with CON group in dose-dependant manner. Conclusions : These results suggest that SHJ can be used as a component of cosmeceuticals for hair care via promoting growth and melanogenesis of hair.

  • Objective : The present study was examined to evaluate the effects of Ecliptae Herba on the production of inflammatory mediators in vivo and in vitro. Methods : In cell viability, all three doses of Ecliptae Herba extract (25, 50 and $100\;{\mu}g/ml$) had no significant cytotoxicity during the experimental period. The increases of NO production and iNOS expression were detected in LPS-activated cells compared to control, but these increases were dose-dependently attenuated by pre-treatment with Ecliptae Herba extract. Results : 1. LPS plays a pivotal roles in inducing to the massive production of pro-inflammatory cytokines such as TNF-$\alpha$, IL-$1{\beta}$ and IL-6 in macrophages. 2. Ecliptae Herba extract reduced the elevated production of cytokines by LPS. 3. Ecliptae Herba extract reduced $PGE_2$ levels in a dose-dependent manner as a consequence of inhibition of COX-2 activity. 4. Ecliptae Herba extract significantly reduced the nuclear translocation of $NF-{\kappa}B$ induced by LPS. 5. In histopathological study, Ecliptae Herba effectively inhibited the increases of hind paw edema, skin thicknesses and inflammatory cell infiltrations induced by carrageenan treatment. Conclusions : These results provide evidences that therapeutic effect of Ecliptae Herba on the acute inflammation is partly due to the reduction of some of inflammatory factors by inhibiting iNOS and COX-2 through the suppression of $NF-{\kappa}B$.
