  • In the present study, we exarnined anti-allergic effect of SGBHB in cultured B cells. B cells were prepared from isolated murine splenocytes and activated by co-treatment of anti-CD40 monoclonal antibody and recombinant IL-4 allergens. Anti-allergic effects of SGBHB in activated B cells were determined by measuring B cell surface activated molecules (CD23+ and CD11a+), and expression levels of IL-$1{\beta}$, IL-6, IL-10, TNF-$\alpha$, IgE, and HRF. The major findings are summarized as follows. 1. SGBHB treatment did not produce significant cytotoxic effects on mouse lung fibroblast cells. 2. SGBHB produced significant inhibitory effect on the expression of B cell surface activated molecules (CD23+ and CD11a) in activated B cells. 3. SGBHB treatment significantly inhibited expression levels of IL-$1{\beta}$, IL-6, and TNF-$\alpha$ mRNAs in activated B cells.IL-6 protein levels were significantly decreased by $100{\mu}g/m{\ell}$ of SGBHB treatrrient, and TNF-$\alpha$ protein levels were decreased compared to the control group, but statistically insignificant. 4. SGBHB treatment significantly increased IL-10 at both mRNA and protein levels in activated B cells. 5. SGBHB treatment significantly inhibited levels of IgE production. Thus, the present data suggest that SGBHB has an anti-allergic effect on activated B cells by controlling irnmune responses, and further implicates the possibility on clinical application as a therapeutic agent.

  • The studies reported here were undertaken to investigate the effects of mercury chloride on immune system of Balb/c mouse employing a flexible tier of in vitro and in vivo assays. Mercury chloride inhibited the proliferative responses of spleen cells to lipopolysaccharide, pokeweed mitogen, and phytohemagglutinin as a dose-dependent manner. This inhibitory effect was observed not only when $HgCl_2$ was added 2nd or 3rd day of 3 days culture period but also when spleen cells was pretreated with $HgCl_2$ for 2 hours. Mercury chloride, however, potentiated the production of IgM and IgG from spleen cells. During the $HgCl_2$ administration by drinking for 3 weeks, the weight gain of mice was significantly blunted than that o control group mice, while no overt signs related to mercury toxicity were noted in any mice of experimental group. There was no change in thymus and spleen weights, and in histological findings of kidney, bone marrow of femur, thymus, spleen, and popliteal lymph node after 3 weeks of mercury exposure. However, $HgCl_2$ induced a significant increase of total serum IgM, IgG including $IgG_1,\;IgG_{2a}\;and\;IgG_{2b}$, and IgE in Balb/c mice. Treatment in vivo with anti-IL-4 monoclonal antibody significantly abrogated the $HgCl_2$-induced increase in total serum IgG1 and IgE. Whereas $HgCl_2$ potentiated total serum IgM and IgG, there was no difference in total serum hemagglutinin to SRBC (Sheep Red Blood Cell) between experimental and control group mice when these mice were immunized with SRBC. All these findings observed in Balb/c mice suggest that mercury perturbates well-orchestrated regulation of immune responses before developing histopathological changes in lymphoid tissues.

  • Objective: The root bark of Ulmus davidiana var. Japonica (Ulmi Radicis cortex, URC) is a medicinal herb used for promoting diuresis and treating dampness. In Korea, URC has long been used as an efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we used 1-fluoro-2,4-dinitrofluorobenzene (DNFB)-induced contact dermatitis (CD) mouse model to investigate the anti-allergic and the anti-inflammatory effects of URC on skin lesion, histopathological changes and specific antibody production. Results: URC treatment, 10 mg/mL, effectively inhibited skin lesions induced by repeated paintings with DNFB. In the histopathological observation, topical application of URC inhibited spongiosis. In addition, URC lowered the production levels of total immunoglobulin and IgG2a in serum. Conclusion: These data indicate that URC has an anti-inflammatory effect that produces an improvement of skin lesions in CD mice.

  • 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.

  • Soeumin-Googwihyangso-san(SGGHSS) has been used for the prevention or treatment of Soeumin-allergic rhinitis. This study was performed to demonstrate anti-allergic and anti-inflamatory effects of SGGHSS methanol extract in HMC cell lines and activated mouse B cells and CD4+ T cells. SGGHSS inhibited the production of TNF-$\alpha$ in PMA plus A23187 activated HMC-1 cells but not that of IL-6, as measured by ELISA. SGGHSS inhibited the expression of CD23 and surface IgE in B cells as determined by flowcytometry. It also inhibited secretion of IFN-$\gamma$ and IgG1, the Th1 related IgG type, but increased that of IL-4 in anti-CD40 and IL-4 treated B cells as measured by ELISA. As for Th cell differentiation, SGGHSS did not much affect IL-4 or IFN-$\gamma$. Taken together, our data showed that SGGHSS exerted an anti-inflammtory effect by inhibiting TNF-$\alpha$ in mast cells and has anti-allergic activity not via inhibition of CD4+ T cell, but via inhibition of B cells. These results suggest some evidence that SGGHSS can be applied to allergic disease.

  • Objectives : The objective of present study is to evaluate anti-inflammatory and anti-allergic effects of Perilla(Perilla frutescens; Labiatae, PF), the roots of Peucedanum praeruptorum(PP) and the root of Scutellaria baicalensis(SB) in vitro and anti-asthmatic effects of mixture of PF, PP and SB(PS) on ovalbumin (OVA)-induced asthma in BALB/c mice. Methods : Anti-inflammatory and anti-allergic effects were observed on the lipopolysaccharide(LPS) treated RAW 264.7 cells through Nitric Oxide(NO) production and RBL-2H3 cells through ${\beta}$-hexosaminidase. Anti-asthmatic effects were observed on the number of inflammatory cells in bronchoalveolar lavage fluid(BALF) and the level of IgE in serum on OVA-induced BALB/c mice. Results : The treatment of PF, PP and SB(12.5, 25, 50, $100{\mu}g/m{\ell}$) resulted in a significant inhibition of NO production in RAW 264.7 cells and mast cell degranulation in RBL-2H3 cells. Oral administration of PS(400mg/kg/day) resulted in a significant reduction in the numbers of eosinophils in BALF and level of IgE in serum. Conclusion : The oral administration of PS is effective in ameliorating the eosinophilic infiltration in vivo and thus can be a good therapeutic candidate for allergic asthma.

  • We investigated the effect of Perilla frutescens (PF) ethanol extract powder (PF-E30) on the local allergic reaction activated by anti-DNP IgE and the mast cell-mediated immediate-type allergic reactions induced by compound 48/80 in a mouse model. One gram of PF powder extracted with 30% ethanol at $80^{\circ}C$ contained 12.3 mg of rosmarinic acid. Oral administration of PF-E30 (0.1 to 0.5 mg/kg body weight) significantly reduced plasma histamine levels and inhibited histamine release from peritoneal mast cells in mice activated by compound 48/80 or anti-DNP IgE. Moreover PF-E30 dose-dependently inhibited the production of antigen-induced IgE. These results indicate that the PF ethanol extract inhibits mast cell-mediated immediate-type allergic reactions in vivo and in vitro.

  • Atopic dermatitis (AD) is a chronic inflammatory skin disease and the pathogenesis of AD is associated with the release of various cytokines/chemokines due to activated $Th_2$ immune responses. Synthetic oligodeoxynucleotides (ODNs) containing unmethylated CpG dinucleotide in the context of particular base sequence (CpG motifs) are known to have the immunostimulatory activities in mice and to convert from Th2 to Th1 immune responses in AD. We aimed to investigate that CpG ODN, especially phosphodiester form, can stimulate the protective immunity in NC/Nga mice with AD. We isolated BMDCs from NC/Nga mice and then, cultured with GM-CSF and IL-4 for 6 days, and treated for 2 days by either phosphorothioate ODN or phosphodiester ODN. CpG ODN-treated DCs resulted in more production of IL-12. When CpG ODN-treated DCs were intravenously injected into the NC/Nga mice, the NC/Nga mice with CpG ODN-treated DCs showed significant improvement of AD symptoms and decrease of IgE level. Histopathologically, the NC/Nga mice skin with CpG ODN-treated DCs showed the decreased IL-4 and TARC expression comparing with non-injected mice. These results may suggest that phosphodiester CpG ODN-treated DCs might function as a potent adjuvant for AD in a mouse model.

  • Soyangin-Hyeongbangpaedok-san(SHBPDS) is used for treating upper respiratory infections, In an effort to investigate the anti-inflammatory effects of SHBPDS, we measured production of several cytokines and immunoglobulin in various immune cells. SHBPDS decreased the secretion of TNF-${\alpha}$, but not that of IL-6 in PMA/A23187 stimulated HMC-1 cells. As for mouse B cells, it induced proliferation and caused differential effects in expressions of surface IgE as determined by flow cytometry and secretions of IgE, IgG1, ILA and INF-${\gamma}$as measured by ELISA but showed little change in CD23 or CD69 expression. SHBPDS increased proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells. Under the Th1/Th2 polarization conditions, SHBPDS at 200 ${\mu}g/m{\ell}$ suppressed the secretion of INF-${\gamma}$ and IL-4. Based on the above results, we conclude that SHBPDS has antiinflammatory activities in mast cells and different immunomodulatroy effects in B cells and Th cells.
