Objective : Juglandis Semen has a function that to invigorate the lung and kidney. And It is commonly used as a supporting agent in the treatment of coughing and bronchitis. This study was performed to investigate the effect of oral administration of Juglandis Semen Extract (JSE) against the experimental asthma induced by ovalbumin. Methods : Asthma was induced to Balb/c mouse by i.p. injection and aerosol immunization with ovalbumin. It was observed the change of the cell number in the BAL fluid. Concentrations of IL-4, IL-5 in splenoc yte were assessed by ELISA, IgG and IgE from serum were calculated by same method. Results : 1. Number of macrophage in BAL fluid was significantly decreased in JSE group compared with control group, but not eosinophil and lymphocyte. 2. Levels of IgG and IgE in serum were significantly decreased in JSE group compared with control group, respectively. 3. Concentration of IL-4 in culture supernatant of splenocyte was significantly decreased in JSE group compared with control group, but there was no significant in IL-5. Conclusion : We found that the effect of JSE extract in asthma was implicated in reduction of IL4released from Th2 cell, and decreases of IgG and IgE from plasma cell. These findings suggest that JSE can produce anti-asthmatic effect, which may play a role in allergen-induced asthma therapy.

The prevalence of atopic dermatitis (AD) in school-age children has increased in industrialized countries. As diet is one of the main factors provoking AD, some studies have suggested that food additives in processed foods could function as pseudoallergens, which comprise the non-immunoglobulin E-mediated reaction. Eosinophil cationic protein (ECP) is an eosinophil granule protein released during allergic reactions to food allergens in patients with AD. Thus, serum ECP levels may be a useful indicator of ongoing inflammatory processes in patients with AD. The purpose of this study was to investigate the effect of consuming MSG in processed foods on serum ECP levels among children with AD. This study was performed with 13 patients with AD (age, 7-11 years) who had a normal range of total IgE levels (< 300 IU/ml). All participants ate normal diets during the first week. Then, six patients were allocated to a processed food-restricted group (PRDG) and seven patients were in a general diet group (GDG). During the second week, children in the PRDG and their parents were asked to avoid eating all processed foods. On the third week, children in the PRDG were allowed all foods, as were the children in the GDG throughout the 3-week period. The subjects were asked to complete a dietary record during the trial period. Children with AD who received the dietary restriction showed decreased consumption of MSG and decreased serum ECP levels and an improved SCORing score on the atopic dermatitis index (P < 0.05). No differences in serum ECP levels or MSG consumption were observed in the GDG. Serum total IgE levels were not changed in either group. In conclusion, a reduction in MSG intake by restricting processed food consumption may lead to a decrease in serum ECP levels in children with AD and improve AD symptoms.

Objectives : The root of Codonopsis pilosula (Fr.) Nannf. (Codonopsis Pilosulae Radix) has been traditionally used as a oriental medicine with an anti-thrombotic, antidiabetic, anticancer, and anti-gastric ulcer effects and immunological adjuvant. In this study, we investigated the effect of 70% ethanol extract of Codonopsis Pilosulae Radix (CPR-E) on ovalbumin (OVA)-induced allergic responses in mice. Methods : Mice were sensitized (1, 8, and 15 days) with OVA and airway challenged(22, 24, 26, 28, and 30 days) to induced allergic responses. CPR-E extract at doses of 50 and 100 mg/kg/body weight was orally administered from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and Th1/Th2 cytokines such as IFN-${\gamma}$ and IL-4 were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : CPR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-${\gamma}$. Based on H&E staining, CPR-E extract inhibited the infiltration of inflammatory cells into lung tissues with histological changes. Conclusions : These results indicate that CPR-E extract has anti-inflammatory and anti-allergic responses through regulating the cytokine balance, suggesting that the extract may be useful for the treatment of allergic inflammatory diseases such as bronchial asthma and allergic rhinitis.

Objectives : Allergy has been described as an inflammatory with hypersensitivity resulting from seasonal or perennial responses to specific allergens. The root of Platycodon grandiflorum (Jacq.) A. DC.(Platycodi Radix; Campanulaceae) has been traditionally used to treat chronic diseases such as bronchitis, asthma, pulmonary tuberculosis, inflammation and hyperlipidemia. In this study, we examined the effect of 70% ethanol extract of Platycodi Radix (PR-E) on ovalbumin (OVA)-induced airway inflammation in mice. Methods : Mice were sensitized and challenged by OVA inhalation to induced chronic airway inflammation, and then were intragastrically administered PR-E extract at doses of 50 and 200 mg/kg/day from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and cytokines such as IL-4 and IFN-${\gamma}$ were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : PR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and Th2 cytokine, IL-4 compared with those in the OVA-induced group. PE-E extract significantly increased the serum level of Th1 cytokine, IFN-${\gamma}$. Based on lung histopathological studies, inflammatory cell infiltration and mucus hypersecretion were inhibited by PE-E extract administration compared to that in the OVA-induced group. Conclusions : These findings indicate that PE-E extract may be useful as an adjuvant therapy for the treatment of bronchial asthma.

Objectives : The aim of this study was to investigate the effect of Chunghwatang (CHT) for atopic dermatitis. Methods : CHT, a verified anti-oxidant and anti-inflammatory effect, was treated in atopic dermatitis animal model to investigate cytokine levels and immunoglobulin production. Results : Clinical skin index was 47.1%, suggesting significant efficacy of CHT in atopic dermatitis treatment. Serum IL-4, IL-6, IL-13, TNF-${\alpha}$ and histamine productions were significantly decreased to 52.3%, 61.8%, 68.0%, 37.4%, and 46.6%, respectively. The production of IL-5 was decreased to 33.3%. The increase of Immunoglobulin IgG1 production along with IgE through the interaction of IgE and IL-4 induced by IL-4 and IL-13 were measured as 20.7% and 23.4%, respectively. Conclusions : The results above, along with the in vitro test results, strongly supports the CHT samples as effective immunomodulator in AD treatments, suggesting its use in clinical practice and basic information for EBM.

Objectives In this study, we investigated the inhibitory effects of Samhwangsasim-tang (S.H) on the allergic response caused by ovalbumin(OVA) sensitization and challenge in BALB/c mice. Methods The experimental animals were divided into five groups; 1) normal as negative control, 2) OVA-sensitized mice, 3) OVA-sensitized mice treated with 200 mg/kg of S.H 200, 4) OVA-sensitized mice treated with 400 mg/kg of S.H 400, and 5) OVA-sensitized mice treated with 5 mg/kg of Dexamethasone (Dex). Antigen sensitization for allergic mouse model was performed with twice injection of OVA for 2 weeks. After secondary injection, S.H was administrated orally into mice every day for 13 days and the inhibitory effect of S.H on allergic responses was evaluated. Results Treatment of S.H into allergic mice reduced significantly ear edema and infiltration of immune cells in ear tissues induced with OVA challenge in a dose-dependent manner. S.H reduced significantly the serum levels of Total Immunoglobulin(Ig)G and IgE, and particularly inhibited the production of OVA-specific IgE, but not OVA-specific IgG. The serum level of proinflammatory cytokine TNF-${\alpha}$ and Th2-associated cytokine IL-4 also were significantly decreased by S.H adminstration in a dose denpendent manner. S.H attenuated OVA-induced secretion of IFN-${\gamma}$, but not IL-12 which is a cytokine inducing the development of Th1 cells. It also reduced significantly the secretion of IL-4, which is a cytokine inducing the development of Th2 cells, after splenocytes were stimulated with OVA. However the secretion of IL-5 and IL-13 was influenced weakly or a little. Conclusions These results indicate that S.H could reduce the allergic response through inhibition of antigen-specific IgE and Th2-inducing cytokines. It suggest that S.H may be available clinically for the treatment of allergic patients.

Background: Atopic dermatitis (AD) is a common chronic inflammatory skin disease. To understand AD, there have been many trials establishing AD animal models. Although various trials to establish AD animal models have been existed, even the mechanisms of AD in animal models are not enough clarified. Objectives: This study assessed AD characteristics induced in Nishiki-nezumi Cinnamon/Nagoya (Nc/Nga) mice following trinitrochlorobenzene (TNCB) treatment for different periods and house dust mite (HDM) treatment to compare each model's immunological patterns, especially with cytokine antibody array tool. Methods: In this study, we exposed Nc/Nga mice to TNCB or HDM extract to induce AD. Nc/Nga mice were divided into 4 groups: control, TNCB 2 weeks-treated, TNCB 8 weeks-treated, and HDM-treated groups. After AD induction, all mice were evaluated by serum immunoglobulin E (IgE) concentration and serum cytokine antibody assays, scoring of skin lesions, scoring of scratching frequency, and histological analysis. Results: The results showed significant differences between groups in serum IgE concentration, skin lesion scores, and scratching frequency. The analysis results for serum cytokine antibody arrays showed that in the TNCB 8 weeks- and HDM-treated groups, but not in the TNCB 2 weeks-treated group, expressions of genes related to the immune response were enriched. Among the histological results, the skin lesions in the HDM-treated group were most similar to those of AD. Conclusions: We confirmed that immunological pattern of AD mice was markedly different between HDM and TNCB treated groups. In addition, the immunological pattern was quietly different dependent on TNCB treated duration.

Background: This study was performed to determine the effects of liposome-encapsulated bee venom (BV) treatment of inflammatory factors in atopic dermatitis (AD) compared with BV treatment. Methods: AD was induced by phthalic anhydride in mice and the effects of BV liposomes were measured. Using Leica Application Suite, thickened epidermis and dermis were measured after BV liposome treatment (0.05 and 0.1 ㎍/mL). The number of stained mast cells and the concentration of immunoglobulin (Ig)E were measured. Serum IgE concentration was analyzed using an enzyme-linked immunosorbent assay. The serum concentrations of interleukin (IL)-1, IL-4, and IL-6 inflammatory cytokines were measured. The levels of messenger ribonucleic acid expression of proinflammatory cytokines and chemokines were measured using reverse transcription polymerase chain reaction. Inhibition of mitogen-activated protein kinase activation, was analyzed on western blot. To measure the transcriptional activity (NF-κB inhibition by BV liposomes), western blots (p65, p-IκB, p50, and IκB) were also performed. Results: The weight of lymph nodes, serum IgE concentrations, morphological changes in the skins from the backs of the mice, and mast cell numbers in inflamed tissues were noticeably lower in the BV liposome treatment group compared with the BV treatment group. The concentrations of pro-inflammatory cytokines (IL-1, IL-4, IL-6) and chemokines (TSLP, CCL22) were also reduced. Activation of mitogen-activated protein kinase (p-ERK and p-p38), and transcriptional activity (p65, p-IκB, p50, and IκB) was strongly suppressed in the BV liposome group. Conclusion: BV liposomes may have a better therapeutic effect than BV for the treatment of AD.

In this study, we investigated the anti-allergic effect of the ethyl acetate fraction of Ecklonia cava (EC-EtoAc) on the immunoglobulin E (IgE)/bovine serum albumin (BSA)-mediated activation of bone marrow-derived cultured mast cells (BMCMCs). We revealed that the $62.5{\mu}g/ml$ of EC-fractions ($EC-CHCl_3$, EC-Hexane and EC-EtoAc) inhibited IgE/BSA-activated ${\beta}$-hexosaminidase release from BMCMCs without cytotoxicity. Especially, EC-EtoAc showed the higher ${\beta}$-hexosaminidase release than the others. Also, EC-EtoAc reduced the expression levels of cytokines such as interleukin (IL)-$1{\beta}$, IL-4, IL-5, IL-6, IL-10, IL-13, interferon (IFN)-${\gamma}$ and tumor necrosis factor (TNF)-${\alpha}$ and a chemokine, thymus- and activation-regulated chemokine (TARC), compared to the only IgE/BSA-treated BMCMCs. Furthermore, EC-EtoAc significantly prevented the binding of IgE to Fc epsilon receptor $(Fc{\varepsilon}R)I$ and reduced the $Fc{\varepsilon}RI$ expression on the sensitized BMCMCs. Taken together, these results suggest that E. cava may be the natural agent with beneficial potentials for the treatment of type I allergic diseases induced by mast cell activation.
