This study was intended to evaluate the anti-atopic effect of Sargassum fulvellum water extract (SFWE). Atopic dermatitis (AD) was induced in BALB/c mice by spreading 2,4-dinitrochlorobenzene (DNCB) to the dorsal skin area. The production of IL-4 and total IgE of the SFWE treated group was significantly less than the DNCB only group. On the other hand, the production of the IFN-γ of SFWE treated group was greater than that of the DNCB only group. In addition, SFWE alleviated the AD symptoms when compared to the DNCB only group and reduced the epidermal thickness and the number of mast cells in histological analysis. In conclusion, these results suggest that the application of SFWE has an anti-atopic activity through the modulation of IL-4 and IFN-γ cytokines, and the total IgE in DNCB-induced BALB/c mice. Therefore, SFWE can be utilized with atopic disease therapies.

Objectives : The aim of this study was to evaluate the effect of Schizonepeta Spica water extract (SS) on the OVA-induced BLAB/c mice allergic rhinitis model.Methods : Thirty two BALB/c mice were equally assigned to 4 groups; the sham group, the control group, the cetirizine hydrochloride (Cet) treatment group, and the SS treatment group. Sham group was sensitized and challenged with saline, and the other groups were sensitized and challenged with OVA. The dosage of SS was 7.6 mg /kg·day, and Cet was 10 mg/kg·day. Nasal rubbing and sneezing were measured by the behavior observation. The concentrations of IL-1β, IL-10, TNF-α and MIP-2 in the sera of allergic rhinitis model were measured by mouse cytokine/chemokine magnetic bead panel kits. Total IgE and OVA-specific IgE were measured by ELISA method. Epithelial thickness and eosinophil infiltration of nasal septum was investigated by histological examination.Results : The clinical symptoms that increased in control group were significantly reduced in SS-treated group. Serum total IgE and OVA-specific IgE in the SS-treated group were significantly reduced compared to the control group. The concentration of IL-1β, IL-10, TNF-α and MIP-2 in SS-treated group showed a significant reduction compared to the control group. The infiltration of eosinophil into nasal tissues of SS-treated group decreased markedly compared to control group, and thickness of nasal septum in nasal mucosa showed a significant reduction compared to control group.Conclusions : According to the above result, it is suggested that SS may inhibit the early and late phase of allergic rhinitis reaction.

The diagnosis of atopic dermatitis (AD) includes a test that checks allergen-mediated skin reactions and a method of measuring the total IgE and allergen-specific IgE in blood. However, these test methods are performed directly on the patient, which cause some pain or discomfort. In addition, the skin response test or IgE may result in false negative in about 20% of patients. In the present study, to identify specific biomarkers, HaCaT cells were used as a human keratinocyte that make up the skin, were treated IL-4 and IL-13 for 24 hours to induce a situation similar to keratinocytes in AD patients. In the HaCaT cells, pro-inflammatory cytokine such as IL-5, IL-6, and MCP-1 were increased by IL-4 and IL-13 and skin barrier proteins was reduced by IL-4 and L-13. This results showed that a situation similar to the stratum corneum of an actual patient is induced in HaCaT cells. And then the secretions of Kallikrein (KLK) 5 and KLK7 protease were checked by enzyme-linked immunosorbent assay (ELISA). It was specifically increased by IL-4 and IL-13. This showed that AD-related protease can be detected at the protein level using keratinocytes that can be taken in a non-invasive manner and suggested the possibility of applying it to AD diagnosis.

Hyperimmunoglobulin E syndrome (HIES) is a rare immunodeficiency disease which is characterized by high serum IgE levels, eczema, and recurrent infections. Herein we present the case of a patient with HIES associated with STAT3 gene ($stat3$) mutation. A 16 year-old girl was admitted to our hospital due to hemoptysis caused by pneumonia with bronchiectasis. She had a history of recurrent skin and respiratory tract infections, such as pneumonia caused by MRSA (methicillin-resistant $Staphylococcus$ $aureus$) and $Pseudomonas$ $aeruginosa$. On physical examination, a broad round shaped nose, oral thrush, and chronic eczematous skin rash over her whole body were found. Laboratory data showed an elevated eosinophil count ($750/{\mu}L$) and total IgE level (5,001 U/mL). The patient's National Institutes of Health (NIH) score for HIES was 44. Direct sequencing of the STAT3 gene revealed that the patient was heterozygous for a missense mutation in the DNA binding domain of the STAT3 protein (c.1144C>T, p. Arg382Trp). HIES should be suspected in patients with recurrent infections and can be confirmed by clinical scoring and genetic analysis.

Objectives : The aim of this study is to investigate the effect of natural carbonated hot spring water (NCHW) on DNCB-induced NC/Nga mice, an atopic dermatitis (AD) model. Methods :At first, NC/Nga mice were prepared and induced to have atopic lesion on their back skin by dinitrochlorobenzene (DNCB). They swam for 20 minutes everyday in tanks where the one is filled with $28^{\circ}C$ NCHW, the other is with $25^{\circ}C$ carbonated hot spring water and another is with artificial carbonated hot spring water (ACHW). After 3 weeks, We assessed the skin clinical score and macroscopic appearance, total IgE, IgG1 levels, WBC differential counting, IFN-${\gamma}$, IL-4, IL-13, TNF-${\alpha}$ production levels and histological changes. Results : There are meaningful results of improving atopic lesion-state by relieving the count of total IgE, IgG1 levels, WBC differential counting, IFN-${\gamma}$, IL-4, IL-13, TNF-${\alpha}$ production levels and recovering skin clinical score in the group with $28^{\circ}C$ NCHW in comparison with the other groups. Conclusions : The NCHW may have potential as an effective treatment for atopic dermatitis.

Objective : The purpose of this clinical research was to investigate the effects of Seunggaltang on patients with atopic dermatitis. Methods : Thirteen patients were treated with Seunggaltang and ten patients were treated with placebo for 8 weeks. We observed skin humidity, skin sebum,, transepidermal water loss, skin melanin, skin erythema, total IgE class and number of allergen. And Clinic Index of Atopic Dermatitis(Extent, Intensity, Subjective symptoms, Total score) was used to evaluate the effects of Seunggaltang. Statistical analysis was performed by using paired sample T-test. Statistical significance was achieved if the probability was less than 5%(P<0.05). The result were as follows : 1. Statistically, Seunggaltang didn't showed significant effect on skin humidity, skin sebum, skin transepidermal water loss, skin melanin and skin erythema. 2. Statistically, Seunggaltang showed significant effect on Clinic Index of atopic dermatitis. 3. Statistically, Seunggaltang didn't showed significant effect on total IgE class and number of allergen. 4. Before and after treatment, the results of blood test and urinalysis were normal. Conclusion : We speculate that Seunggaltang has some therapeutic effects in mitigating the symptoms of atopic dermatitis.

Atopic dermatitis is a chronic inflammatory skin disease characterized by pruritic and erythromatous skin lesions. In this study we examined the suppressive effects of SJJY on der f induced atopic dermatitis in NC/Nga mic, and concluded as follows: Oral administration of SJJY significantly decreased the severity score in the skin lesions at the dosage of 6.6 mg/25g/day for 8 weeks. SJJY significantly suppressed the infiltration of inflammatory cells into skin compared with control, and decreased the expression of CD4, CD8, CD20 and CCR3 in the skin lesions. SJJY significantly decreased the level of IgE in the serum compared with control, and the levels of IgM, IgG2a and IgG2b were also decreased. SJJY significantly decreased the levels of IL-6, but not TNF-a, in the serum compared with control. The levels of IFN-$\gamma$ was significantly increased in the supernatant of CD3/CD28 activated cultured splenocytes from the SJJY treated mice. The levels of IL-4 and IFN-$\gamma$ in the supernatants was much less in the der f activated splenocytes from SJJY treated mice than control. SJJY significantly increased the total number of cells in lymph node, while decreased the total number of skin compared with control. SJJY increased the number of CD3+ and CD4+ cell compared with control, while decreased the number of CD4+/CD25+ and CCR3+ cells in the PBMC. SJJY increased the number of CD3+, CD4+, CD8+, CD4+/CD25+, NKT+, CD3+/CD69+ cells compared with control, while decreased the number of B220+/IgE+, B220+/CD23+ cells in the lymph node. SJJY significantly decreased the number of CD3+/CD69+, CCR3+, B220+/IgE+, CD11b+/Gr-1+ compared with control in the skin lesions. Taken together, these results suggested that SJJY has suppressive effects on atopic dermatitis by the regulation of immune system and has potential as a therapeutics for atopic dermatitis. Further studies on molecular mechanisms on immune regulation are needed.
