  • (S)-(+)-3(3,4-dihydroxy-phenyl)-acrylic acid 2,2-dimethyl-8-oxo3,4-dihydro-2H,8H-pyrano[3,2-g]Chromen-3-yl-ester (Compound 6, C6) is synthesized from (S)-(+)-decursin and attenuates the pathophysiologic progression of asthma in a ovalbumin-induced asthmatic mouse model. In the present study, we examined the effect of C6 on spontaneous apoptosis of eosinophils and neutrophils of normal and asthmatic subjects. C6 increased the apoptosis of asthmatic eosinophils in a dose-dependent manner, but it inhibited neutrophil apoptosis. C6 has no effect on apoptosis of normal eosinophils and neutrophils. LY294002, an inhibitor of PI3K, rottlerin, an inhibitor of $PKC{\delta}$, Ro-31-8425, an inhibitor of classical PKC inhibitor, PD98059, an inhibitor of MEK, and BAY 11-7085, an inhibitor of NF-${\kappa}B$, blocked the inhibitory effect on apoptosis of asthmatic neutrophils due to C6. These results indicate that C6 may be valuable as a therapeutic agent for the treatment of asthma.

  • Objectives : To clarify the possible effects of Sinapis Semen and Raphani Semen on the development of pulmonary eosinophilic inflammation in a asthmatic mouse model. Methods : BALBav/c mice were sensitized to OVA followed intratracheally and by aerosol allergene challenges. We investigated the effect of Sinapis Semen and Raphani Semen on airway hyperresponsiveness, eosinophiic infitratio, immune cell phenotype, The2 cytokine product, and OVA-spedific IgE production. Results : Total lung cells, eosinophils, and lung leukocytes, OVA specific IgE levels, and Th 2cytokine levels such as IL-5, IL-13, IL-17, TNF-alpha, and eotaxin in BALF were reduced compared with those of OVA sensitized asthma mice (control). The absolute numbers of $CD3^+$, $CD3^+/CD69^+$, $CD3^-/CCR3^+$, $CD4^+$, $CD8^+$, $Gr-1^+/CD11b^+$, $B220^+/CD22^+$, $B220^+/IgE^+$ cells in lung tissiues significantly reduced compared to those of control. Specially total lung cells in BALF and the absolute number of $CD3^+/CD69^+$ and, $B220^+/IgE^+$ cells in lung tissiue effectively reduced in Sinapis Semen plus Raphani Semen compared to those of Sinapis Semen and Raphani Semen. Conclusions : These results indicate that Sinapis Semen plus Raphani Semen has deep inhibitory effects on airway inflammation and hyperresponsiveness in asmatic mouse model and also has effect of suppression of IL-5, IL-13, IL-17, OVA specific IgE production in BALF. The results verified that Sinapis Semen, Raphani Semen, and Sinapis Semen plus Raphani Semen could act as a immunomodulator which possess anti-inflammatory and anti-asthmatic property by modulating the relationship of Th1/Th2 cytokine imbalance.

  • 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.

  • Objective : Although management of asthma has become increasingly effective, its cure remains elusive, necessitating a new modality to prevent or eliminate causes triggering clinical progress. Based in the clinical experiences, a novel decoration Cheongsangbiyeum (CSB), has been developed to treat asthma, which consists of Polyporus, Semen Myristicae, Pericarpium citri Reticulatae, Rhizoma Cimicifugae, Cortex Albizziae, Fructus Rubi, Rhizoma Zedoariae, and Rhizoma Rhei. In the current study, its anti-asthmatic efficacy was evaluated using a mouse model of asthma. Methods : Experimental allergic asthma was induced by repeated intraperitioneal sensitization and intranasal challenge of ovalbumin (OVA). Water extract of CSB (1 mg/mouse/day) was administrated orally whereas control mice on given with identical volume of phosphate-buffered saline (PBS) for 5 days during the course of antigen challenge. When airway hyperreactivity(AHR) measured by ${\bata}-methacoline-induced$ airflow obstruction was compared, AHR of CSB-treated mice was significantly lower than those of control mice, indicating that CM extract can attenuate an asthmatic symptom. Airway recruitment of leukocytes and eosinophils was also markedly reduced by CSB treatment suggesting that oral treatment of CSB can alleviate the airway inflammation. For a better understanding of possible mechanisms underlying anti-asthmatic effet of CSB, cytokine (IL-4, IL-5, IL-13 and $IFN{\gamma}$ levels in bronchoalveola lavage fluid (BALF) and lung tissues were determined. Results : The results showed that cytokine levels were significantly lowered by CSB treatment. Additionally, number of draining lymph node cells was significantly lower than those of control mice. These data indicate that CSB suppress in vivo allergen-specific response. However, notably, levels of type 2 cytokines such as IL-5 and IL-13 were more profoundly influenced. Moreover, in vitro OVA-specific proliferative response and type 2 cytokine (IL-4, IL-5 and IL-13) production lymph node cells was markedly decreased in CSB-treated mice, whereas their $IFN{\gamma}$ production was not significantly altered Thrse data clearly showed a preferential inhibition of type 2 T cell (Th2) response by CSB treatment. This finding was also supported by serum antibody data showing that levels of OVA-specific type 2 antibodies, IgE and IgG1, in CSB-treated mice were significantly lower than in control mice, while type 1 antibody, IgG2a level m rather higher than controls, although the difference was in significant. Conclusions : In conclusion, oral administration of CSB attenuates asthmatic manifestations including AHR ad airway recruitment of eosinophils in a mouse model which possibly results from selective inhibition of Th2 cell response to allergen. Our data suggest a potential clinical application of CSB for control of allergic asthma.

  • Hubakmawhang-tang (HMT), listed in Geumgweyoryak, is an oriental medicine used for the symptoms of asthma, such as cough and dyspnea. In this study, we investigated the HMT effects on ovalbumin-induced asthmatic in mice. We examined weight changes, airway hyperresponsiveness, histopathological abnormalities, immune cell infiltrations, immunoglobulin and inflammatory cytokine levels, and spleen body weight ratios in asthmatic mice. HMT inhibited airway hyperresponsiveness, immune cell infiltration, and airway remodeling and caused a significant lowering of serum IgE and IgG1 levels. The asthmatic mice had elevated IL-4 levels in lung tissue and this elevation was effectively prevented by HMT. HMT did not cause changes in body weight or in the spleen body weight ratio. Therefore, HMT might have an anti-asthmatic effect in the ovalbumin-induced mouse model.

  • Objective : In the present study, we investigated the pharmacological profile of the aqueous extract of $Patrinia$ $scabiosaefolia$ Fischer ex Link (EPS) and $Patrinia$ $villosa$ Jussieu (EPV) for its anti-asthmatic activities. The purpose of this study is to ascertain if EPS result in better anti-asthmatic activities and functional outcome as compared with EPV. 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 EPS, EPV on the recruitment of pulmonary inflammatory cells, various immune cell phenotypes, Th1/Th2 cytokine gene expression and production and histamine production in serum. Results : In BALB/c mice, we found that EPV-treated groups had more effectively suppressed inflammatory cell infiltration of lung and BALF, B220+IgE+, CD11b+Gr-1+ cell population in lung and these occurred by suppressing the gene expression of IL-4, IL-5 and IL-4 cytokine production in BALF and serum. Conclusions : These results suggest that EPV may play an important role in the control of anti-asthmatic activities by down-regulation of Th2 cytokine (especially IL-4, IL-5). In general, EPV has shown a better anti-asthmatic activities compared to EPS.
