  • Objective : Allergic asthma is a chronic airway disease that affects millions of people in the developed world. The disease is characterized by concurring airway inflammation, Th2 cytokine production, increased mucus secretion, airway hyperresponsiveness (AHR) to inhaled antigen, and pulmonary fibrosis. To investigate the therapeutic and anti-asthmatic effects of Drynariae Rhizoma (DR), we examined the influence of DR on the development of pulmonary eosinophilic inflammation and airway hyperresponsiveness in a mouse model of allergic asthma. Methods : In this study, BALB/c mice were systemically sensitized to ovalbumin (OVA) followed intratracheally, intraperitoneally, and by aerosol allergen challenges. We investigated the effect of DR on airway hyperresponsiveness, pulmonary eosinophilic infiltration, various immune cell phenotypes, Th2 cytokine production and OVA specific IgE production in a mouse model of asthma. Results : In asthmatic mice, we found that DR.treated groups had suppressed eosinophil infiltration, allergic airway inflammation and AHR by suppressing the production of IL-5, IL-13 and OVA specific IgE. Conclusions : Our data suggest that the therapeutic mechanism by which DR effectively treats asthma is based on reductions of Th2 cytokines (IL-5), eotaxin, OVA-specific IgE production and eosinophil infiltration.

  • Electroacupuncture(EA) is commonly used in various diseases. In the present study, the effect of EA in the allergic mouse model was examined. Allergy is generated via immunological mechanism and non-immunological mechanism. Mast cells activated dy those mechanisms get to release various substances such as histamine, leukotrienes, prostaglandin, TNF-$\alpha$, IL-4, IL-6, etc. which induce allergic reactions and the following inflammatory responses. To evaluate the anti-allergic effects of EA, mortality, ear swelling response, vascular permeability and cytokine secretion were investigated in EA group and non-EA group of which mice were compound 48/80-induced allergy model or PCA model. Compound 48/80 induces allergic reaction via non-immunological mechanism and PCA model is generated through the same mechanism with immediate-type(Type1) allergic reaction, one of immunological allergic reactions. EA inhibited compound 48/80-induced ear swelling response but did not inhibit the systemic anaphylaxis. EA also inhibited passive cutaneous anaphylaxis(PCA) activated dy anti-dinitrophenol IgE. In addition, EA inhibited IL-6 and TNF-$\alpha$ secretion from 48 h PCA in mice. These results indicate that EA may be used for the treatment of mast cell-mediated allergic diseases, especially immediate-type(Type 1) allergy and non-immunologically mediated allergy.

  • Astragali Radix(AR), is a popular tonic herb prescribed for 'insufficient qi' in Korea, Japan and China. The present study examined the effect of AR ethanol extract on ovalubumin induced allergic mouse model. AR administration reduced levels of IFN-gamma, Interleukin(IL)-4, IL-5 and total IgE in the OVA induced allergic inflammation. It also protected the upper airway respiratory epithelium from being damaged by the OVA induced inflammation. Taken together, our results showed that the use of AR alone proved to down-regulate Th1 and Th2 cytokine production and play a protective role in tissue damage in allergic disease.

  • This study aimed to present a mouse model of ovalbumin (OVA) induced allergic diarrhea under a sub-barrier system and investigate the development of gut microbiota in this model. Male BALB/c mice were systemically sensitized with OVA or sham-sensitized with saline, and followed by oral OVA intubation, leading to OVA-specific acute diarrhea. Compared with sham-sensitized mice, sera OVA-specific IgG1 and total IgE in OVA-sensitized mice were dramatically elevated, and the number of mast cells was greatly increased in the jejunum of the OVA-sensitized mice. Principle component analysis of the DGGE profile showed that samples from group of OVA-sensitized mice and group of sham-sensitized mice were scattered into two different regions. Real-time PCR analysis showed that the number of 16S rRNA gene copies of Lactobacillus in the colon of OVA-sensitized mice decreased significantly, while there was no significant difference in the number of Bifidobacterium and total bacteria. In conclusion, OVA-specific allergic diarrhea was successfully induced under a sub-barrier system, and changes of allergic reactions during induction was coupled with changes in gut microbiota, especially the number of colonic Lactobacillus, but the role of gut microbiota in the development of food allergic reactions needs to be further evaluated.

  • Objective : Allergic rhinitis (AR) is an allergic inflammation of the nasal airways. Socheongryong-Tang traditionally has been used in Korea for treatment of allergy diseases. In the present study, we investigated whether SCRT suppresses the progression of AR in vivo and in vitro. Method : In this study, we investigated the effect of oral administration of SCRT on the Ovalbumin(OVA)-induced allergic rhinitis mouse models. Additionally, to find a possible explanation for the anti-inflammation effects of SCRT, we evaluated the inflammatory cytokine levels in LPS-stimulated mouse inflammation cell (RAW264.7) and mouse splenocyte. Results : The finding of this study demonstrated that SCRT reduced mast cells and inflammation cells infiltration in OVA-induced nasal cavity. Additionally, SCRT inhibited the production of inflammatory cytokines in splenocyte. However SCRT don't inhibited the production of inflammatory cytokines in RAW264.7 cells. Conclusion : Taken together, our results showed that oral administration of SCRT beneficial effects in allergic rhinitis, suggesting that SCRT might be a useful candidate for the treatment of allergic rhinitis.

  • Objectives : Platycodon Root is frequently used in traditional medicine to treat inflammatory diseases of the throat. The purpose of this study was to characterize the effect of the EtOH extract of fermented Platycodon grandiflorum on the ameliorative effects on the Antipruritic Effect of atopic dermatitis mouse model induced by compound 48/80 and ovalbumin (OVA)-induced allergic responses in mice. Methods : In the present study, we examined the anti allergic effect of Platycodon grandiflorum (PR) and its fermented production (FPR) in several mouse model. We measured acute ear edema in a mouse model caused by TPA and consecutively histological change of Ear tissue was observed by hematoxylin and eosin (H&E) staining. and also Scratching behaviors by compound 48/80 was investigated. The levels of allergic mediators such as immunoglobulin (Ig) E, and anti-oxidant markers such as SOD and MDA in the sera of OVA induced allergic mice were measured by enzyme-linked immunosorbent assay. Results : FPR inhibited compoud 48/80-induced scratching behavior in mice, as well as acetic acid-induced writhing in mice. The anti-scratching behavioral effect of FPR was more potent than PR. FPR extract significantly decreased the serum levels of IgE and MDA compared with those of OVA control group. Conclusions : These results indicate that Anti allergic effect of Platycodon grandiflorum is enhanced by fermentation with Saccharomyces cerevisae and FPR may be useful for protection from the itching reactions, which are IgE-mediated representative skin allergic diseases.

  • Allergies are immediate hypersensitive responses to antigens and interleukin (IL)-4 is involved in the initiation and development of allergic responses. $Rb_1$ has been known to have a variety of biological activities including anti-inflammatory activity, but the effect of $Rb_1$ on allergic responses is not known yet. The present study was undertaken to examine whether $Rb_1$ has an inhibitory effect on allergic response in mouse model. In allergic mouse model, our results showed that topical application of $Rb_1$ on atopic dermatitis (AD)-like skin lesions improved skin condition and inhibited starching behaviors. In addition, $Rb_1$ application not only suppressed mRNA expression of IL-4 and IL-10, but also prevented the nuclear factor of activated T cells 1 transcription. Moreover, $Rb_1$ application suppressed IL-4's secretion. Taken together, these results suggest that $Rb_1$ has a potent inhibitory effect in AD-related T cell cytokine production and may be a candidate for therapeutic agent in allergy.

  • Objectives : Tongqiao-tang(TQT) has been commonly used for the treatment of common cold, rhinitis etc. Nowadays, TQT becomes one of the most frequently used medicines for allergic rhinitis, but the mechanism of TQT in vivo isn't investigated yet. This study was performed to investigate the effect of TQT on OVA-induced allergic rhinitis mouse model by calculating serum cytokines and IgE. Methods : 8 weeks aged male BALB/c mice were divided into three groups: the normal group, the control group and the medicated group (the TQT group). Each group was consisted of 15 mice. The TQT group was administered TQT extract orally one time a day (1g/kg) from the $1^{st}$ day of experiment till the $26^{th}$ day. The control group and the normal group were administered normal saline by the same method of the TQT group. To induce the allergic rhinitis in the control group and the TQT group, mice of each group were sensitized intraperitoneally with ovalbumin (OVA) solution at the $1^{st}$, the $7^{th}$ and the $14^{th}$ day. After then, intranasal sensitization was performed by dropping 0.1% OVA solution in nasal cavity at the $22^{th}$, the $24^{th}$ and the $26^{th}$ day. At the $27^{th}$ day, the mice were killed and the changes of interferon-${\gamma}$, interleukin-4, interleukin-5, total IgE and OVA-specific IgE were checked. Results : IFN-${\gamma}$ was increased 36% more in the TQT group than that in the control group. IL-4, IL-5, the total IgE and OVA-specific IgE were decreased in the TQT group as compared with the control group and these results were statistically significant. Conclusions : Considering the above experimental results, this study showed that TQT could reduce the allergic reaction in allergic rhinitis. Advanced studies are required to investigate the further mechanisms of TQT.

  • Objectives : This study was performed to compare the effect of two Cudrania tricuspidata cultivars; Sancheong native (CT) and varieties in china(SCT) on immediate hypersensitivity of the anaphylactic type and Ova-induced allergic asthma mouse model by calculating serum cytokines and IgE. Methods : We investigated the free radical scavanging effect and quantify total phenol contents and total flavonoids of two Cudrania tricuspidata cultivars; Sancheong native(CT) and varieties in china(SCT). The sample was extracted by 80% EtOH. To induce the allergic asthma, in the control group and the CT group, mice of each group were sensitized intraperitoneally with ovalbumin (OVA) solution at the 1st, the 7th and the 14th day. After then, sensitization was performed by aerosol allergen challenges with 1% OVA solution intratracheally at the 21th, the 23th, 25th and the 27th day. At the 29th day, the mice were killed and the changes of interferon-${\gamma}$, interleukin-4, 5 and 10, total IgE and OVA-specific IgE in serum were checked. Results : CT inhibited compound 48/80-induced systemic anaphylaxis 90% with a dose of 100 mg/kg body weight at 1 hr before injection of compound 48/80. In the allergic asthma mouse model, IFN-${\gamma}$ was did not increased in the CT and SCT group than that in the control group. IL-4, IL-5, the total IgE and OVA-specific IgE were decreased in the CT group as compared with the control group and these results were statistically significant. Conclusions : Considering the above experimental results, this study showed that Sancheong native cultivar could reduce the allergic reaction.
