Objectives The purpose of this study is to investigate the effect of KKHS on atopic dermatitis in an in-vivo experiment using an NC/Nga atopic dermatitis mouse, which has histological and clinical similarities to this condition in humans. Methods To investigate the effect of KKHS on atopic dermatitis (AD), we evaluated atopic dermatitis-like skin lesions by clinical skin index and analyzed immunological parameters in peripheral blood mononuclear cells(PBMCs), splenocytes, draining lymph node(DLN) and performed skin histology in ears and dorsal skin of atopic dermatitis of NC/Nga mouse in vivo. Results In vivo, clinical skin severity score was significantly lower in the KKHS group than in the control group. IgE, IL-6, TNF-${\alpha}$, IgM, IgG2a and IgG2b levels in serum decreased remarkably in the KKHS group than in the control group, and the level of IFN-${\gamma}$ production which is secreted from Th1 cell was increased by KKHS. After this experiment we analyzed immunological cells ($CD3^+$, $CD19^+$, $CD4^+$, $CD8^+$, $CD3^+CD69^+$, $CD4^+CD25^+$ and $CD49b^+$) by flow cytometry. It results that the total absolute number of $CD3^+$, $CD19^+$, $CD4^+$ and $CD8^+$ cells were recovered as much as normal state, and the level of $CD3^+CD69^+$ in isolated DLN and PBMCs were significantly decreased, and total absolute number of $Gr-1^+$, $CD11b^+$ and $CD3^+$ in dorsal skin of NC/Nga mouse were decreased by KKHS. We analyzed ear, DLN, and neck-back skin after biopsy and dyeing by hematoxyline/eosin(H&E), toluidine staining (mast cells marker). KKHS were very effective to the histological symptoms which are in dermal and epidermal thickening, hyperkeratosis and inflammatory cell infiltration. Ear thickness was significantly decreased compared with the control group and the size of inflammatory lymphocytes cells (ILC) and plasma cells (PC) in DLN were also decreased. Conclusions KKHS on atopic dermatitis in an in-vivo experiment using an NC/Nga atopic dermatitis mouse was very effectiveness to the atopy dermatitis treatment.

Allergy skin prick test and intradermal test represent one of the major tools in the diagnosis of IgE-mediated diseases like as atopic asthma, allergic rhinitis, atopic dermatitis, food and drug allergy, and insect bite when properly performed. Skin tests are of particular importance in fields such as allergen standardization, pharmacology, and epidemiology. Even if skin tests seem easy to perform, adequate and proper interpretation requires well-trained physicians who can recognize the numerous factors that may modify the results of skin tests.

This study was conducted with 60 adult males who visited the Atomi Cooperative Clinic(Atomi Dermatology/Pediatrics/Oriental Clinic) in Seoul between May 2003 and December 2004; they were divided into three groups, each of which consisted of 20 persons, according to the level of erythma and then each group was subdivided to consist of ten according to whether they received skin treatment and care. The standard care provided to two groups involved topical steroids and oriental medicines prescribed by a dermatologist and a oriental doctor, respectively. 5th-grade topical steroid ointment was applied to the face and 3rd-grade to the limbs; a oriental medicine was administered in a lukewarm state half an hour after meals three times a day. To determine how special and systematic skin treatment and care was helpful in treating atopy, a skin treatment system was applied to the experimental group while the control group was provided with standard care alone. By using Mexameter(MX18) manufactured by ck-mpa as a measuring tool, the inflammation level was observed at the right antecubital space during each visit to the clinic. In view of the re suits, introduction of the systemic skin care for A. D to legitimate treatment provided by a medical institution is expected to be an appropriate supplementary treatment for adult patients who suffer from frequent recurrence of atopic dermatitis.

This study was undertaken to identify differences between atopic and non-atopic dogs in three rapid screening immunodot assays as well as the ability of the assays to predict the results of intradermal skin testing (IDST) or Favrot diagnostic criteria (FDC). Twenty-nine dogs diagnosed with canine atopic dermatitis (CAD) were selected as the atopic group. Twenty-five dogs without CAD were included as the non-atopic group. Three types of immunodot assays were conducted on all serum samples from both groups: Allercept E-screen 2nd generation (ES2G), Canine Allergic Tendency Reference Test (ALERT), and Asan Easy Test Canine IgE (AETC). IDST, which included 39 allergens, and immunodot assays were performed concurrently in 13 dogs from the atopic group and compared. While there were no significant differences in positivity between the two groups in the evaluation of ALERT (P = 0.435) and AETC (P = 0.313), positivity in ES2G testing was significantly higher in the non-atopic group than the atopic group (P = 0.038). The ES2G, ALERT, and AETC results showed fair (${\kappa}=0.235$), slight (${\kappa}=0.133$), and slight (${\kappa}=0.014$) accordance with IDST, respectively. The outcomes of ES2G, ALERT, and AETC indicated poor (${\kappa}=-0.211$), slight (${\kappa}=0.106$), and slight (${\kappa}=0.087$) agreement with FDC. In conclusion, rapid screening immunodot assays were not useful for the diagnosis of CAD. These assays may provide a supplementary method for predicting the results of IDST in atopic dogs.

Atopic dermatitis is a chronic inflammatory skin disease caused by a variety of genetic and environmental factors, dysregulation of immunological response, as well as dysfunction of the skin barrier proteins. The purpose of this study is to develop an ELISA kit suitable for evaluating the expression of skin barrier proteins. Proteins were obtained from the skin via AriNo and D-Squame patches. The efficiency of protein collection from the skin, using the Arino patch, was shown to be more effective than using D-Squame; while the efficiency of lysis using 0.1% Triton-X100 was higher than that of other lysis solutions, including 0.1 M Tris-HCL, 0.1% Tween-20, and 5 mM KOH. Recombinant skin barrier proteins, such as filaggrin and involucrin, were produced by molecular biological methods. Monoclonal antibodies against filaggrin and involucrin were produced by immunization of mice, fusion of spleen cells and myeloma cells, as well as a selection of antibody-producing hybridoma cells. The filaggrin expression in the skin of subjects suffering from atopic dermatitis was lower than that in normal mice. Involucrin expression was not altered between normal individuals and subjects with atopic dermatitis. These findings contribute to an elucidation of the importance of the skin barrier protein expression in atopic dermatitis and the development of a diagnostic kit for atopic dermatitis.

Gastrodia elata Blume is a well-known kind of natural products used as a folk medicine for thousands of years. However, anti-atopic dermatitis-like effects of G. elata Blume had not been evaluated until now. The aim of the present study is to investigate the protective effects of water extract from the roots of G. elata Blume (GE) on 2, 4-dinitrochlorobenzene-induced atopic dermatitis-like skin lesions using balb/c mice. Combination treatment of GE (at a dose of 12.5 mg/kg body weight by administrated per os + 0.5 mg/cm² as ointment to apply on ear and dorsal skin) was significantly inhibited spleen weight, ear thickness, levels of serum immunoglobulin E and number of mast cells, compared with that of 2, 4-dinitrochlorobenzene-included groups without GE. Furthermore, combination application by oral administration plus by ointment of GE significantly inhibited the histamine release from rat peritoneal mast cells. These results suggest that combination treatment of oral administration plus ointment form of GE could be helpful as a potentially natural pharmaceutical treatment on atopic-like dermatitis.

The rhizomes of Dioscorea japonica Thunb. are widely consumed as food and also used to treat diabetes and polyuria in Korea. This study was undertaken to study the anti-atopic dermatitis effects of a 95% ethanolic extract (DJE) of D. japonica in an oxazolone-stimulated murine model of atopic dermatitis (AD). The therapeutic effects of DJE on AD-like skin lesions were assessed on both ears. DJE (1%) or dexamethasone (0.5%; the positive control) were applied to skin lesions for three weeks. Serum levels of IgE and IL-4 were assessed by ELISA (enzyme-linked immunosorbent assay). Histopathological examinations were performed by hematoxylin and eosin (H&E) and toluidine blue staining and revealed DJE significantly reduced dermal thickness and inflammatory cell infiltration when applied to oxazolone-treated ear skin. DJE-treated AD mice also showed lower serum levels of IgE and IL-4 than oxazolone-stimulated controls. Our findings demonstrate DJE might be a useful safe, topical agent for the treatment of atopic diseases.

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.
