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.

The ore minerals, mainly composed of sericite, talc, and halloysite, were investigated for their inhibitory effect on the allergic inflammation in mice by measuring the serum IgE level, inflammatory cytokine production, and histamine and ${\beta}$-hexosaminidase releases. When the mice were ovalbumin (OVA)-challenged prior to the ore mineral treatment, the IgE level in the serum decreased significantly. The ore minerals significantly reduced the productions of IL-4 and the tumor necrosis factor-${\alpha}$ in the bronchial alveolar lavage fluid challenged with OVA. The inflammatory infiltrates, found in the lung of the OVA-challenged mouse, were also notably decreased following the ore mineral treatment. The ore minerals significantly reduced the release of histamine and ${\beta}$-hexosaminidase from the RBL-2H3 cells. These results suggest that the ore minerals may be useful as potent inhibitors of the allergic inflammation in mice.

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.

Previously we showed that biodegradable nanoparticles containing poly-IC or CpG oligodeoxynucleotide (ODN) together with ovalbumin (OVA) were efficient at inducing MHC-restricted presentation of OVA peptides in dendritic cells. The CTL-inducing activities of the nanoparticles were examined in the present study. Nanoparticles containing poly-IC or CpG ODN together with OVA were prepared using biodegradable polymer poly(D,L-lactic acid-co-glycolic acid), and then were opsonized with mouse IgG. The nanoparticles were injected into the tail vein of mice, and 7 days later the OVA-specific CTL activities were measured using an in vivo CTL assay. Immunization of mice with the nanoparticles containing poly-IC or CpG ODN together with OVA elicited potent OVA-specific CTL activity compared to those containing OVA only. In accordance with these results, nanoparticles containing poly-IC or CpG ODN together with OVA exerted potent antitumor activity in mice that were subcutaneously implanted with EG7.OVA tumor cells. These results show that encapsulation of poly-IC or CpG ODN together with antigen in biodegradable nanoparticles is an effective approach for the induction of potent antigen-specific CTL responses in vivo.

Recent study has demonstrated an increasing prevalence of food allergy in Korean children. Specific probiotic bacteria may promote potentially anti-allergenic processes through induction of Th1-type immunity and enhance the regulatory lymphocyte. This study investigated whether orally administrated probiotics could suppress allergic responses in an ovalbumin (OVA)-induced allergy mouse model. Thus, female C3H/HeJ mice were orally sensitized with OVA and cholera toxin for 4 weeks. Lactobacillus acidophilus AD031, Bifidobacterium lactis AD011, and L. acidophilus AD031 plus B. lactis AD011 were fed to mice from 2 weeks before the sensitization. The OVA-induced mice that were not treated with probiotics had significantly increased serum levels of OVA-specific IgE and IgG1, and OVA-specific IgA in feces. However, the mice treated with probiotics suppressed production of the OVA-specific IgE, IgG1, and IgA. The level of IL-4 was significantly lower, and the levels of INF-$\gamma$ and IL-10 were significantly higher in the mice treated with probiotics than that in the non-treated mice. The groups treated with probiotics had decreased levels of degranulated mast cells, eosinophil granules, and tail scabs. These results indicate that L. acidophilus AD031 and B. lactis AD011 might be useful for the prevention of allergy.

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.

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.

Objectives : The present study was to investigate the effect of extract of Chelidonii herba (ECH) on the proliferation and activation of eosinophils which were prepared from lung cells of asthma-induced mouse by ovalbumin (OVA) treatment. Methods : C57BL/6 mouse was exposed to OVA three times a week for 6 weeks. The mouse lung tissues were dissected out, chopped and dossiciated with collagenase (1 ${\mu}g$/ml). Eosinophils were activated by rIL-3/rmIL-5 co-treatments. The lung cells were treated with ECH, incubated for 48 hr at $37^{\circ}C$, and analyzed by flow cytometery, ELISA, RT-PCR, and immuno-histochemical analysis. Results : In FACS analysis, number of granulocyte/lymphocyte, $CD3e^-$/$CCR3^+$, $CD3e^+$/$CD69^+$, $CD4^+$ and $CD23^+$/$B220^+$ in asthma-induced lung cells were significantly decreased by ECH treatment compared to the control group. And mRNA expression for IL-4, IL-5, IL-13, CCR3 and eotaxin in asthma-induced lung cells, which was induced by rIL-3 plus rmIL-5 treatments, was significantly decreased by ECH treatment. In ELISA analysis, production levels of IL-3, IL-5, IL-13 and histamine in asthma-induced lung cells, which were induced by rIL-3 plus rmIL-5 co-treatment, were significantly decreased by ECH treatment. ECH treatments significantly inhibited the proliferation of eosinohils prepared from asthma-induced mouse lung tissues compared to the non-ECH treated control cells. Immunohistochemical analysis revealed that ECH treatment significantly decreased the levels of eosipnphil activation compared to non-treated cells. Conclusions : The present data suggested that Chelidonium majus L. may have an effect on the inhibition of parameters associated with asthma responses in eosinpophils, and thus implicate the possibility for the clinical application of Chelidonium majus L.
