  • 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.

  • Allergic rhinitis is a growing tendency to increase. Following this tendency, allergic rhinitis is lively studied also in Korean oriental medicine. Bupleuri Radix (BR) has been used for many inflammatory diseases, but experimental backgrounds are not enough to treat allergic rhinitis. So in this study, effects of BR on OVA-induced allergic rhinitis model of BALB/c mice were examined. Thirty two BALB/c mice are equally devided into four groups; control group, OVA group, OVA+BR group, OVA+Cet group. The OVA, OVA+BR and OVA+Cet groups were induced allergic rhinitis by sensitizing to OVA. And then saline solution included BR (10.6 mg/kg body weight) was administered to the OVA+BR group orally. The number of nasal rubbing and nasal sneezing was evaluated for 10 days and later serological and histological changes were analyzed. Serological analysis included the serum levels of cytokines and chemokines (IL-4, IL-5, IL-12, MCP-1, MIP-2), total IgE and OVA-specific IgE levels in serum. Histological analysis included thickness of nasal septum, eosinophil counts changes of nasal mucosa, infiltration of eosinophil in nasal mucosa and histological changes of nasal mucosa. The number of nasal rubbing and nasal sneezing was significantly decreased in the OVA+BR group. The serum levels of IL-4, IL-5, MCP-1, MIP-2 were significantly decreased in the OVA+BR group but the serum levels of IL-1β had not significance. Total IgE and OVA-specific IgE levels in serum were decreased in the OVA+BR group, but total IgE levels in serum had only significance. Thickness of nasal septum, eosinophil counts of nasal mucosa and infiltration of eosinophil in nasal mucosa were significantly decreased in the OVA+BR group. From the results of this study, we think that BR has an effect on improvement of allergic rhinitis by improving nasal rubbing and nasal sneezing, reducing histological changes of nasal mucosa and infiltration of eosinophil in nasal mucosa, inhibiting increasing of the serum levels of cytokines, chemokines and total IgE.

  • Mast cells play a key role in IgE-mediated allergic response. We investigated whether Swertia pseudochinensis Hara extract (SPE) inhibits IgE-mediated allergic response in mast cells and an allergic animal model. Additionally, we explored SPE's mechanism of action in mast cells. Our results showed that SPE inhibited both antigen-stimulated degranulation and the production of TNF-α and IL-4 in bone marrow-derived mast cells (BMMCs) and rat basophilic leukemia (RBL)-2H3 cells. SPE also suppressed allergic response in IgE-mediated passive cutaneous anaphylaxis (PCA) in mice. As for the mechanism of action of SPE in mast cells, it inhibited the activation of Syk kinase, a critical signaling protein in the FcεRI-mediated signaling pathway, and also the activation of LAT, a downstream adaptor protein of Syk. We further observed the reduced activation of mitogen-activated protein (MAP) kinases (P38, ERK1/2, and JNK) and Akt in mast cells. Our results described for the first time that SPE has an anti-allergic effect by suppressing mast cells through the inhibition of Syk kinase. Therefore, SPE may be useful for the treatment of type I allergic diseases.

  • Hot-water($100^{\circ}C$) and cold-water($4^{\circ}C$) extracts of Taraxacum officinale root were assessed for the effects of innate and adaptive immune responses in mice. Hot water extracts(TO-100) and cold water extracts(TO-4) did not affect the viability of macrophages at concentrations below to 18 mg/ml and 8 mg/ml, respectively. The thioglycollate-induced macrophages cultured with TO-100 and TO-4 produced a significantly higher quantity of various cytokines, such as IL-6 and IL-12, than those treated with medium. This shows that the extracts potently stimulated the innate immune response. When mice were subcutaneously immunized(sc) with OVA+FIA(Freund's incomplete adjuvant)-emulsified TO-100, TO-100 did not affect the production of IgE, but enhanced the production of IgG1, IgG2a and IgG2b. The culture supernatant obtained from the splenocytes of mice treated with OVA+FIA-emulsified TO-100 also evidenced elevated levels of both OVA-specific Th1-type(IFN-$\gamma$) and Th2-type cytokines(IL-4, IL-6 and IL-10). These results suggested that TO-100 can modulate the immune responses to allergens in mice.

  • Oral administration of soluble antigen can induce peripheral tolerance to the antigen. This study was conducted to evaluate whether gamma-irradiated ovalbumin (OVA) can induce oral tolerance. To investigate this, we administrated intact or irradiated OVA to mice, induced allergic response using intact OVA and alum, then compared humoral and cellular immune responses. Mice treated with gammairradiated OVA had less OVA-specific IgE compared with those who were administered intact OVA. There was no difference in levels of OVA-specific IgG+A+M, IgG1, and IgG2a. Splenocytes of mice administered irradiated OVA showed similar OVA-specific T cell proliferation and secretion of IFN-γ and IL-4. However, there was an increase in IL-2 and a decrease of IL-6 secretion in mice treated with irradiated OVA. These results indicate that gamma-irradiated OVA have similar effects to intact OVA on antigen tolerance.

  • OVA를 항원으로 한 식품알레르기 마우스 모델을 이용하여 감태 물 추출물의 알레르기 억제 효과를 확인하였다. 먼저, OVA로 면역한 마우스의 비장세포에 감태 물 추출물을 첨가하여 배양한 후, 배양 상층액의 IgE antibody와 IL-4 및 IFN-$\gamma$ cytokine 분비량을 측정하였다. 그 결과, $10\sim100{\mu}g$/mL 농도의 감태 물 추출물 첨가로 비장세포의 IgE 분비량이 농도 의존적으로 감소하였고, IL-4 및 IFN-$\gamma$ 분비량도 감태 물 추출물 첨가 농도가 증가할수록 감소하였다. 감태의 알레르기 억제능을 in vivo 실험을 통해 확인하기 위해 OVA로 알레르기를 유발한 마우스에 감태 물 추출물을 복강주사 한 후 혈청과 비장세포의 IgE 분비능을 확인하였다. 혈청의 항체 분비량 측정 결과, 1, 5 및 10 mg/kg BW 농도의 감태 물 추출물 투여군이 PBS 투여군에 비해 유의적으로 낮은 OVA-specific IgE 분비량을 보였다. 반면, IgG1과 IgG2a 분비량은 추출물 투여군과 PBS 투여군 사이에 유의적인 차이를 보이지 않았다. 또한 비장세포의 IgE 분비량이 5 및 10 mg/kg BW 농도의 감태 물 추출물의 복강주사에 의해 감소함을 확인하였다. 이상의 결과를 통해 감태 물추출물이 IgE 분비량의 유의적인 감소 효과를 통해 식품알레르기 반응을 효과적으로 억제할 수 있을 것으로 사료된다.

  • Objectives: The purpose of this study is to investigate the effects of Yijungtang(YJT) on atopic dermatitis in an in-vitro and in-vivo experiment using a RBL-2H3 mast cells and a NC/Nga atopic dermatitis mouse. Methods: In-vitro experiment, IL-4, IL-13 mRNA expression were evaluated by a real-time PCR, IL-4, IL-13 production by ELISA and transcription factor as GATA-1, GATA-2, NF-AT1, NF-AT2, AP-1 and NF-kB by western blotting. In-vivo experiment, clinical skin score we evaluated by, hematology and Serum total IgE and IgG1 of NC/Nga atopic dermatitis mouse, cytokine level, total number of cell, Immunohistochemical staining and Histological features of auxiliary lymph node(ALN), draining lymph node(DLN), peripheral blood mononuclear cells(PBMCs) and dorsal skin tissue in NC/Nga mouse. Results: YJT decreased IL-4, IL-13 mRNA expression, IL-4, IL-13 production and prominently decreased the expression of mast cell specific transcription factors including GATA-2, NF-AT2, c-Fos and NF-kB. YJT oral administration reduced the levels of skin severity scores. It also decreased the level of inflammatory cytokines such as IL-5, IL-13, histamine and IgE in the serum. It elevated IFN-gamma level in the spleenocyte culture supernatant but decreased. $CD3e^+$, $CD19^+$, $CD4^+$, $CD8^+$, $CD3e^+CD69^+$, $CD11b^+Gr-1^+$, $CCR3^+$ in the PBMCs, $CD4^+$, $CD8^+$, $CD3e^+CD69^+$, $B220^+CD23^+$ in the ALN, $CD4^+$, $CD3e^+CD69^+$ in the ALN and $CD4^+$, $CD11b^+Gr-1^+$ in the dorsal skin. Histological examination showed that infiltration levels of immune cells in the skin of AD-induced NC/Nga mice were much improved by YJT oral administration. Conclusions: The anti-allergic activities of YJT may be mediated by down-regulation of Th2 cytokines, such as IL-4 and IL-13, through the regulation GATA-2, NF-AT2 and NF-kB transcription factors in mast cells. YJT would be regulate molecular mediators and immune cells which are functionally associated with atopic dermatitis induced in NC/Nga mice, and may play an important role in recovering AD symptoms.
