The aim of this study was to examine inhibitory effects of pine needle ethanol extracts (PNEE) on atopic dermatitis (AD). To determine inflammatory activity PNEE was added to LPS-induced murine peritoneal macrophages for an in-vitro test. In addition, anti-AD test was carried out by spreading PNEE on the dorsal skin of 2,4-dinitrochlorobenzene (DNCB)- induced BALB/c mice. It was confirmed that the nitric oxide (NO) secretion was suppressed when $1{\sim}50{\mu}g/mL$ of PNEE were added to LPS-induced murine peritoneal macrophages. Moreover, levels of TNF-${\alpha}$, IL-6, and IL-$1{\beta}$, were decreased. For the anti-AD test, PNEE alleviated symptoms of the erythema in DNCB-induced mice. Furthermore, the IFN-${\gamma}$ secretion of the group treated with PNEE was increased in splenocytes from DNCB-induced mice compared to the positive control, while IL-4 secretion diminished. Through these results, we can conclude that PNEE can inhibit AD by modulating the IFN-${\gamma}$, IL-4 cytokines production and inhibiting inflammation.

Atopic dermatitis is a chronic inflammatory skin diseases caused by skin barrier dysfunction. Allium victoralis var. Platyphyllum (AVP) is a perennial plant used as vegetable and herbal medicine. The purpose of this study was to suggest that AVP is a new cosmetic material by examining the effects of AVP on the skin barrier and inflammatory response. A bibliometric network analysis was performed through keyword co-occurrence analysis by extracting author keyword from 69 articles retrieved from SCOPUS. We noted the anti-inflammatory activity shown by the results of clustering and mapping from network visualization analysis using VOSviewer software tool. HPLC-UV analysis showed that AVP contains 0.12 ± 0.02 mg/g of chlorogenic acid and 0.10 ± 0.01 mg/g of gallic acid. AVP at 100 ㎍/mL was shown to increase the mRNA levels of filaggrin and involucrin related to skin barrier function by 1.50-fold and 1.43-fold, respectively. In the scratch assay, AVP at concentrations of 100 ㎍/mL and 200 ㎍/mL significantly increased the cell migration rate and narrowed the scratch area. In addition, AVP suppressed the increase of inflammation-related factors COX-2 and NO and decreased the release of β-hexosaminidase. This study suggests that AVP can be developed as a functional cosmetic material for atopy management through skin barrier protection effects, anti-inflammatory and anti-itch effects.

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.

This study was conducted to evaluate the anti-inflammatory activity and clinical efficacy of a sample (A.C.C. extracts) obtained by distillation extraction of 14 herbal medicines including Phellodendron bark. To confirm this, the amount of nitric oxide (NO) produced by the cells in RAW 264.7 cells stimulated by lipopolysaccharide (LPS) and the changes in the production of inflammatory cytokines such as tumor necrosis factor (TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$ and IL-6 were determined. The results showed that A.C.C. extracts strongly inhibited the production of NO and inflammatory cytokines increased by LPS without cytotoxicity. In addition, A.C.C. extracts showed strong bacterial reduction rates of 99.9% in Pseudomonas aeruginosa, Staphylococcus aureus, MRSA (Methicillin-resistant Staphylococcus aureus), Candida albicans and Streptococcus mutans. These findings indicate that A.C.C. extracts are effective ingredients with a strong antimicrobial effect together with an anti-inflammatory effect. In addition, when A.C.C. extracts were applied to infants and toddlers who were suffering from diaper rash, itching, and perspiration symptoms, symptoms of rash, atopy, rash, itching, and heat rash were improved. After the lapse of time, it was visually confirmed that it was considerably relaxed. These findings confirm that A.C.C. extracts comprise a clinically effective anti-inflammatory and anti-bacterial agent that alleviates symptoms such as diaper rash and fever and may therefore be an effective alternative to inflammatory diseases.

This work was carried out to investigate the anti-inflammatory effects of Paulownia coreana Uyeki on abirritant, atopy and acne skin. Paulownia coreana Uyeki has been used as a traditional medicine having anti-febrile, anti-inflammation effect in Korea, Paulownia coreana Uyeki loaves were extracted with 70% EtOH. Its superoxide anion radical scavenging activity and inhibitory effect on LPS-induced NO production were examined. The extract inhibitied the generation of NO and $PGE_2$ induced by LPS in the macrophage cell line (Raw 264.7). Consistent with the inhibitory effects on No and $PGE_2$ generation, the extract inhibited expression of iNOS and COX-2. In further study, it was found that the extract prevented $IkB-{\alpha}$ degradation, as demonstrated by western blot analysis of $IkB-{\alpha}$ protein level. However, the extract treatment did not affect cell viability at $100{\mu}g/mL$ concentration in both human skin fibroblast and Raw 264.7 cells in vitro. Thus, the present study suggests that Paulownia coreana Uyeki leaves extract have significant anti-inflammatory activity and potential as an anti-irritation material.

It is very important to control the inflammation of the skin because it can develop into diseases such as atopy as well as scarring and aging. In this work, we recently identified the in vitro synthesis of specialized pro-resolving mediators (SPMs) known to control inflammation in the human body and the applicability of cosmetics. Using recombinant protein of lipoxygenase from Glycine max, we succeeded to prepare mixtures of mono- or di-hydroxy DHA named as S-SPMs and used them for in vitro efficacy test. To investigate anti-inflammatory effect of S-SPMs, mRNA level of TNF-α and IL-6 were analyzed. Under UVB exposed condition, expression of both were decreased by S-SPMs treatment. And we observed reduced production of nitric oxide (NO) by S-SPMs application under the condition with diesel particulate matter (DPM). At the same experimental condition, malondialdehyde (MDA) production was decreased by S-SPMs, indicating the inhibitory effect of S-SPMs in lipid peroxidation. In addition, S-SPMs treatment resulted in reduction of matrix metalloproteinases-1 (MMP-1) expression and elevation of procollagen type I synthesis. Together with this, mRNA level of filaggrin and loricrin were increased by S-SPMs, indicating enhancement of skin barrier function. These results demonstrate that S-SPMs is a good candidate to develop as a cosmetic ingredient for anti-inflammation, anti-wrinkle, and improvement of skin barrier function.

Gut microbiota produce dietary metabolites such as short-chain fatty acids, which exhibit anti-inflammatory effects. Free fatty acid receptor 2 (FFA2, formerly known as GPR43) is a specific receptor for short-chain fatty acids, such as acetate that regulates inflammatory responses. However, the therapeutic potential of FFA2 agonists for treatment of atopic dermatitis has not been investigated. We investigated the efficacy of the FFA2 agonist, 4-chloro-α-(1-methylethyl)-N-2-thiazoylylbenzeneacetanilide (4-CMTB), for treatment of atopic dermatitis induced by 2,4-dinitrochlorobenzene (DNCB). Long-term application of DNCB to the ears of mice resulted in significantly increased IgE in the serum, and induced atopic dermatitis-like skin lesions, characterized by mast cell accumulation and skin tissue hypertrophy. Treatment with 4-CMTB (10 mg/kg, i.p.) significantly suppressed DNCB-induced changes in IgE levels, ear skin hypertrophy, and mast cell accumulation. Treatment with 4-CMTB reduced DNCB-induced increases in Th2 cytokine (IL-4 and IL-13) levels in the ears, but did not alter Th1 or Th17 cytokine (IFN-γ and IL-17) levels. Furthermore, 4-CMTB blocked DNCB-induced lymph node enlargement. In conclusion, activation of FFA2 ameliorated DNCB-induced atopic dermatitis, which suggested that FFA2 is a therapeutic target for atopic dermatitis.

Atopic dermatitis induced NC/Nga mice were used to investigate the efficacy of BDH(Baedokhwan) on the recovery of dermatitic symptoms through its influence on the immune related factors and histological changes. First of all, BDH treated group showed improvement of atopic dermatitis with naked eye observation, and significant decrease of clinical index(CI) was observed after 14 weeks. And Infiltration of leukocytes was suppressed in BDH treated group, and the thickness of hypertrophied epidermis and dermis were decreased. In dorsal skin, BDH treated group showed significant decrease of the ratio of CD3+, CD11b+/Gr-1+ immune cells by 52.8%, 25.2, respectively. And also significant decrease the level of IL-5 mRNA and IL-13 mRNA by 44.4%, 28.0, respectively. In PBMC and serum, BDH treated group showed an decrease of CD4+/CD45+, B220+/CD23+, CD4+, CD8+, CD4+/CD25+ immune cells by 35.0%, 12.6%, 42.7%, 31.6% and 55.6%, respectively, and the level of histamine was decreased by 39.0%. The results above indicated that BDH clinically used for atopic dermatitis treatment has objective validity, and therefore can be provided as the basic data for anti-allergic and anti-inflammatory studies.

Objectives : Hibiscus (Hibiscus sabdariffa L.) is rich in antioxidants such as flavonoids and anthocyanins and is known to have anti-inflammatory activity and anti-aging function of the skin, but there is no study on its effect on the skin barrier. This study aim to investigate the positive effect on the skin barrier by confirming the effect of water extracts of Hibiscus sabdariffa L. (WEHS) on the tight junction-related gene expression. Methods : The antioxidant efficacy of WEHS was investigated through ABTS and DPPH assays, and 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium was performed to examine the effect on cell viability. quantitative Reverse transcription polymerase chain reaction and immunoblot analysis were performed to confirm the effect of WEHS on the expression of tight junction-related genes, and immunofluorescence microscopy was used to confirm the movement of Claudin 1 protein into tight junctions. Results : WEHS showed strong antioxidant activity and induced an increase in both mRNA and protein expression levels of Claudin 1 among tight junction-related genes. The strong localization of Claudine 1 protein increased by WEHS to the tight junction was confirmed by immunofluorescence microscopy. Conclusions : Hibiscus was confirmed through this study to show antioxidant activity and the function of promoting the expression of the tight junction Claudin 1 gene, suggesting that Hibiscus can be used as a material for the prevention and treatment of skin moisturizing and atopy, which have an important influence on tight junction.
