Abstract
Atopic Dermatitis (AD) is a prolonged reverting skin ailment with characteristically distributed
skin lesions. In the previous decades, researchers had shown a marked interest in AD due to
its increased prevalence in developed countries. Although different strategies including biological
and immune modulators are available for the treatment of AD, each has certain limitations. The
researchers had shown considerable interest in the management of AD with herbal medicines. The
establishment of herbal drugs for AD might eliminate local as well as systemic adverse effects associated
with long term use of corticosteroids and also higher cost of therapy with biological drugs.
The present review discusses the traditional East Asian herbal medicines and scientific data related
to newer herbal extracts or compositions for the treatment of AD. In vivo animal models and in
vitro cell cultures, investigated with herbal medicines to establish a possible role in AD treatment,
have also been discussed in the paper. The paper also highlights the role of certain new approaches,
i.e. pharmacopuncture, a combination of allopathic and herbal medicines; and novel carriers
(liposomes, cubosomes) for herbal drugs on atopic skin. In conclusion, herbal medicines can be a
better and safe, complementary and alternative treatment option for AD.

Abstract
Atopic dermatitis (AD) is a common relapsing inflammatory skin disease characterized by severe pruritus that seriously affects the quality of patients' life. There is an increasingly large amount of research demonstrating that traditional Chinese medicine (TCM) including herbal formulae and bioactive ingredients exerts pharmacological effects on atopic dermatitis. It has been a long history of TCM being used to treat atopic dermatitis, especially in preventing disease recurrence, maintaining long-term remission, and reducing disease burden. Nowadays, both of TCM monomer preparations and traditional formulae are still widely used. This review focuses on TCM as well as its bioactive ingredients for the treatment of AD, from the perspectives of animal model construction, pharmacodynamic mechanisms and clinical studies of formulae. To be more specific, the regulation and molecular mechanisms of the herbal formulae and bioactive ingredients of TCM are investigated, and the latest clinical research on TCM formulae is discussed. Furthermore, it provides a summary of the strengths and utilities of TCM, and will be useful for doctors who use Chinese medicine for treatment or researchers who select candidates for clinical treatments or further high-quality clinical studies.

Abstract
Background and Objectives: Zea m 1 is a pollen allergen, which is present in maize, is accountable for a type I hypersensitivity reaction in all over the world. Several effective medications are available for the disorder with various side effects. Design and verification of a peptide-based vaccine is a state-of-art technology which is more cost effective than conventional drugs. Materials and Methods: Using immunoinformatic methods, the T cell epitopes from the whole structure of this allergenic protein can be predicted. Worldwide conserved region study among the other pollen allergens has been performed for T cell predicted epitopes by using a conservancy tool. This analysis will help to identify completely conserved HLA (human leukocyte antigen) binding epitopes. Lastly, molecular docking study and MHC-oligopeptide complex binding energy calculation data are applied to determine the interacting amino acids and the affinity of the epitopes to the class II MHCmolecule. Results: The study of criteria-based analysis predicts the presence of two epitopes YVADDGDIV and WRMDTAKAL on this pollen allergen. Conclusions: The T cell epitopes identified in this study provide insight into a peptide-based vaccine for a type I hypersensitivity reaction induced by Zea m 1 grass pollen allergenic protein.

Abstract
BACKGROUND The anti-inflammatory actions of Polygonum cuspidatum, Angelica gigas, Sophora flavescens and Arctium fruit are well known. Nonetheless, effects of herbal combination (PASA) or its fermentation by microorganisms (F-PASA) on the allergic response remain unknown. PURPOSE We investigated whether PASA or F-PASA could inhibit IgE/antigen complex (IgE/Ag)-mediated allergic responses. METHODS To evaluate and compare anti-allergic actions of PASA and F-PASA, we performed cell viability, β-hexosaminidase activity, ELISA assays for cytokines and eicosanoids, immunoblot analysis, HPLC analysis and passive cutaneous anaphylaxis (PCA) models. RESULTS F-PASA had stronger anti-degranulation actions (IC50, 510.9 µg/ml) than PASA (IC50, 1,261 µg/ml) without cytotoxicity until 2000 µg/ml in IgE/Ag-activated RBL-2H3 cells. Additionally, F-PASA inhibited formation of tumor necrosis factor-α (IC50, 147.4 µg/ml), interleukin-4 (IC50, 213.4 µg/ml), prostaglandin D2 (IC50, 42.40 µg/ml) and leukotriene C4 (IC50, 157.9 µg/ml). Moreover, F-PASA dose-dependently inhibited the phosphorylation and expression of proteins that are related to the FcεRI and arachidonate cascades. Consistent with in vitro studies, F-PASA from 25 to 100 mg/kg also suppressed IgE/Ag-induced PCA reaction more than PASA did in mice. In phytochemical analysis, using PASA and F-PASA, F-PASA showed a higher level of emodin-8-O-β-d-glucoside, whereas the level of arctiin, an artigenin glycoside, was reduced compared with that using PASA. CONCLUSION These findings indicate that F-PASA, including both artigenin and emodin-8-O-β-d-glucoside, possesses stronger anti-allergic properties. Therefore, F-PASA may be useful as a functional food or as a phytomedicine for allergic diseases.

Abstract
Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases, which is affected by several factors. Anti-histamines, steroids, and immunosuppressive agents have been used for the treatment of AD. However, many studies have reported that long-term use and abuse of these drugs causes many side effects. This study was performed to evaluate the ameliorative effect of green tea extract on AD-like lesions in NC/Nga mice. Green tea extract from tannase digest (GTT), beta-hexosaminidase, and histamine were measured in IgE-antigen complex-stimulated RBL-2H3 cells. Dorsal skin application of house dust mite-ointment induced AD-like symptoms in NC/Nga mice. Dermatitis scores, skin moisture, transepidermal waterloss (TEWL), thickness of skin and ear, T-cell proliferation, levels of immunoglobulins and cytokines, and infiltration of mast cell were measured to assess the degree of AD induction. Skin moisture and TEWL were measured using probes, and ELISA was performed to measure the immunoglobulin and cytokine levels in blood. GTT was selected based on its ability to inhibit the release of beta-hexosaminidase and histamine in IgE-antigen complex-stimulated RBL-2H3 cells. Oral administration of GTT significantly suppressed the skin inflammation and symptoms of AD-like skin lesions in NC/Nga mice. GTT may have a potential therapeutic effect in the treatment of AD.

Abstract
Spleen tyrosine kinase (Syk) is a critical target protein for treating immunoreceptor signalling-mediated allergies. In this study, a virtual screening of an in-house Chinese medicine database followed by biological assays was carried out to identify novel Syk inhibitors. A molecular docking method was employed to screen for compounds with potential Syk inhibitory activity. Then, an in vitro kinase inhibition assay was performed to verify the Syk inhibitory activity of the virtual screening hits. Subsequently, a β-hexosaminidase release assay was conducted to evaluate the anti-mast cell degranulation activity of the active compounds. Finally, tanshinone I was confirmed as a Syk inhibitor (IC50 = 1.64 μM) and exhibited anti-mast cell degranulation activity in vitro (IC50 = 2.76 μM). Docking studies showed that Pro455, Gln462, Leu377, and Lys458 were key amino acid residues for Syk inhibitory activity. This study demonstrated that tanshinone I is a Syk inhibitor with mast cell degranulation inhibitory activity. Tanshinone I may be a potential lead compound for developing effective and safe Syk-inhibiting drugs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jageum-Jung (JGJ) is an oriental herbal formula comprising five herbs (Melaphis chinensis Bell, Cremastra variabilis Nakai, Knoxia valerianoides Thorel, Euphorbia lathyris L., and Moschus moschiferus L.). It has been used for detoxification and treating cancer and inflammatory diseases in China, Japan, and Korea. However, the mechanism of action of JGJ on keratinocyte inflammatory response is poorly understood. AIM OF THE STUDY In the present study, we investigated the anti-inflammatory mechanism of JGJ and studied the effects of JGJ on atopic dermatitis-like skin lesions in mice. MATERIALS AND METHODS We elucidated the anti-inflammatory and anti-inflammatory effects of JGJ on tumor necrosis factor-α/interferon-γ (TNF-α/IFN-γ)-treated human keratinocyte cells, IgE-sensitized RBL-2H3 cells, and 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD)-like mice, respectively. RESULTS The results showed that JGJ suppressed the production and mRNA revels of IL-8, IL-6 and, conspicuously, both TARC and RANTES. JGJ inhibited nuclear translocation of the inflammatory transcription factors NFκB and STAT-1. Moreover, JGJ improved AD-like skin lesions in DNCB-treated mice and inhibited degranulation of mast cell. CONCLUSIONS The results of this study suggest that JGJ can be considered as a candidate agent for AD treatment.

Abstract
Davallia mariesii Moore (Drynaria rhizome extract (DRE)) is widely known for its efficacy in treating inflammation, arteriosclerosis, and bone injuries. This study evaluated whether treatment with DRE inhibited FcɛRI-mediated allergic responses in the RBL-2H3 mast cells and investigated the early- and late-phase mechanisms by which DRE exerts its antiallergic effects. IgE anti-DNP/DNP-HSA-sensitized RBL-2H3 mast cells were tested for cytotoxicity to DRE, followed by the assessment of β-hexosaminidase release. We measured the amounts of inflammatory mediators (e.g., histamine, PGD2, TNF-α, IL-4, and IL-6) and examined the expression of genes involved in arachidonate and FcεRI signaling pathways. In addition, we confirmed the antiallergic effects of DRE on passive cutaneous anaphylaxis (PCA) in mice. DRE inhibited RBL-2H3 mast cell degranulation and production of allergic mediators in them. In early allergic responses, DRE reduced expression of FcεRI signaling-related genes (e.g., Syk, Lyn, and Fyn) and extracellular signal-regulated kinase phosphorylation in mast cells. In late allergic responses, DRE reduced PGD2 release and COX-2 expression and cPLA2 phosphorylation in FcɛRI-mediated mast cells. Lastly, 250-500 mg/kg DRE significantly attenuated the IgE-induced PCA reaction in mice. These findings provide novel information on the molecular mechanisms underlying the antiallergic effects of DRE in FcɛRI-mediated allergic responses.

Abstract
BACKGROUND Colitis is a well-known subtype of inflammatory bowel disease and is caused by diverse factors. Previous research has shown that KIOM-MA elicits anti-inflammatory and anti-allergic effects on various diseases. KIOM-MA-128, our novel herbal formula, was generated from KIOM-MA using probiotics to improve the therapeutic efficacy. We investigated whether KIOM-MA-128 has protective activity in a mouse model of acute colitis induced by dextran sodium sulfate (DSS). METHODS Colitis was induced by DSS administered to ICR mice in drinking water. KIOM-MA-128 (125 or 250 mg/kg) was orally administered once per day. The body weights of the mice were measured daily, and colonic endoscopies were performed at 5 and 8 days. Colon length as well as histological and cytokine changes were observed at the end of drug administration. RESULTS KIOM-MA-128 has pharmacological activity in an acute colitis model. KIOM-MA-128 reduced the loss of body weight and disease activity index (DAI) and inhibited the abnormally short colon lengths and the colonic damage in this mouse model of acute colitis. Moreover, KIOM-MA-128 suppressed pro-inflammatory cytokine expression and maintained the integrity of the tight junctions during DSS-induced colitis. CONCLUSION The results indicated that KIOM-MA-128 protects against DSS-induced colitis in mice and suggested that this formula might be a candidate treatment for inflammatory bowel disease (IBD).
