  • The present study aimed to investigate whether the polymorphisms in the TSLPR gene are associated with atopic and asthmatic disease in the Korean population. We identified eleven single nucleotide polymorphisms (SNPs) and two variation sites in the TSLPR gene, including the promoter region. The genotype and allele frequencies of g.33G>C of the TSLPR gene in asthma patients were significantly different from the respective frequencies of the control group (P = 0.006 and 0.003, respectively). Our additional analysis showed that the genotype and allele frequencies of the g.33G>C and g.19646A>G of the TSLPR gene were significantly associated in the atopic asthma patients rather than in the non-atopic asthma patients (genotype frequencies; P = 0.0001 and 0.0003 respectively, allele frequencies; P = 0.0005 and 0.0001 in that order). Our results suggest that the SNPs of the TSLPR gene could be associated with the susceptibility to atopic asthma in the Korean population.

  • Asthma is an inflammatory disease of airways that is induced by Th2 cytokines and inhibited by Th1 cytokines. In this study we wanted to investigate the effect of SCT and BJT on eosinophilla and cytokines of BALF in a mouse model established airway inflammmation. Asthma was induced to male c57/bl6 mice. Allergen-specific antibody responses, cytokine$(IL-4,\;IL-5,\;INF-{\gamma})$, and eosinophil inflammation of the airways were investigated on the BALF and splenocyte. SCT and BJT effectively induced $INF-{\gamma}$ and inhibited IL-4, IL-5 as well as eosinophilic inflammation when SCT and BJT were administered. Total Ig E level in the BALF decreased. SCT was more effectiveness than BJT. It is considered that SCT and BJT have faborable effect on the asthma because the asthma specific series of abnormalities in respiratory system were decreased.

  • Objective : The purpose of this study was to investigate the effects of Gamisagunja-tang(GS) on the airway hyper-reactivity (AHR), cytokine production and T cell activation during the ovalbumin (OVA)-induced allergic asthma in mice. Materials and Methods : BALB/c mice were sensitized and challenged with 100 mg of OVA and 1 mg of aluminum potassium sulfate intraperitoneally on days 1 and 7. On day 14, mice were challenged on 3 consecutive days with 5% OVA. AHR and bronchoalveolar fluid (BALF), total inflammatory cell count and the production of cytokines were measured. Results : GS significantly suppressed the infiltration of inflammatory cells in the lung tissue and AHR. GS significantly down regulated the production of IL-4, IL-5 and increases of $INF-{\gamma}$ in BALF. GS reduced the population of eosinophils from lung and spleen in OVA-induced allergic asthma. GS reduced the population of $CD4^{+}$ $CD69^{+}$ $CD25^{-}$ T cells in OVA-induced allergic asthma Conclusion : These results suggest that GS may inhibit the production of IL-4, IL-5 and infiltration of eosinophils and be beneficial oriental medicine for allergic asthma.

  • Objective : Propolis (PP) has been used in oriental medicine. PP has various biological activities. However, its immunoregulatory and anti-inflammatory activities have not been well studied. In this study, I investigated these activities of PP by using ovalbumin-induced allergic asthma in mice. Methods : To examine the effect of PP on allergic asthma, mice were sensitized with $100{\mu}g$ of OVA and 1mg of aluminum potasssium sulfate (Alum; Sigma) intraperitoneally on day 0 and 7. On day 14, mice were challenged on consecutive 3 days with 5% OVA and AHR was assessed 24 hours after the last challenge. To examine severity of AHR, I examined the population of eosinophiles and T cells in spleen and lung and cytokine production in T cells. Futhermore, I examined histological changes during the OVA-induced allergic asthma. Results and Conclusion : PP reduced the population of eosinophil and CD4+ T cells on the OVA-induced AHR mice model. PP also inhibited IL-4 production but increased INF-g production in T cells. These results suggest that PP may be beneficial material for allergic asthma.

  • Sjogren-Larsson syndrome (SLS) is a rare autosomal recessive neurocutaneous disorder with worldwide incidence of 0.4 per 100,000 people. It is characterized by the triad of congenital ichthyosis, spastic diplegia or quadriplegia, and mental retardation. Herein we report a 2-year-old male child with SLS, asthma, and recurrent pneumonia. SLS was confirmed by a molecular genetics study that revealed a deletion mutation in the ALDH3A2 gene. An ALDH3A2 gene mutation results in dysfunction of the microsomal enzyme fatty aldehyde dehydrogenase and impaired metabolism and accumulation of leukotriene B4, which is a key molecule and a pro-inflammatory mediator in developing allergic diseases, especially asthma. An increased level of leukotriene B4 has been reported in SLS patients. As far as we are aware, this is the first report of SLS associated with asthma and recurrent pneumonia. In conclusion, pediatricians should be aware of and evaluate patients with SLS for possible associated asthma and allergic disorders.

  • Background: Nowadays asthma is considered to be an inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia. Production of cytokines by bronchial epithelial cells may contribution to the local accumulation of inflammatory cells in patients with bronchial asthma. In many recent studies molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objectives: We aimed to identify the clinical effects of Chuongsangboha-tang and the effects of Chuongsangboha-tang on serum cytokines in asthmatic patients. Materials and Methods: The subjects consisted of 36 patients with asthma who had been treated with Chuongsangboha-tang for four weeks. Chuongsangboha-tang is an herbal decoction which has been used of the traditional therapeutic agent of asthma. PFT, Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA), blood eosinophil, serum IgE, Serum IL-4, IL-5, IFN- were checked before and 4 weeks after treatments. Results: Treatment with Chuongsangboha-tang for four weeks resulted in significant increase in FEV1.0%, PEFR%, QLQAKA. The blood eosinophil, serum IgE, IL-4 and IL-5 in asthmatic patients increased significantly compared to the normal control group, while the serum IFN-decreased significantly. Conclusions: This study shows that Chuongsangboha-tang has effects on improvement of pulmonary function and quality of life in asthmatic patients. Obviously, further research concerning this is still necessary.

  • Recently a major goal in asthma therapy is to reduce or prevent the inflammatory response of airway. Eosinophilic accumulation in the tissue is a prominent feature of allergic diseases including asthma. Production of chemokines by bronchial epithelial cells may contribute to the allergic inflammation by recruiting eosinophils. In this study we evaluated the inhibitory effect of Gamichungsangbohatang (GMCSBHT), used traditionally in treating asthma, on secretion of chemokines for eosinophils in human A549 epithelial cells. Chemokines such as eotaxin, RANTES, IL-8 were inhibited in a dose-dependent manner, but IL-16 showed no inhibition by GMCSBHT. These findings indicate that GMCSBHT might be a therapeutic value in treating asthma by suppression of chemokines secretion associated with local accumulation of eosinophils.

  • The present study was carried out to investigate the effect of Chihyo-san (CHS) administration on asthma induced by Alum/OVA treatment in the mice. In CHS-treated animal group, lung weight, which was increased after asthma induction, was significantly decreased, and total number of cells in the lung, peripheral lymph node (PLN) and spleen tissue was significantly decreased in CHS-treated group compared to the asthma control group. The number of immune cells including natural killer (NK) cells in asthmatic animals was largely regulated by CHS treatment, showing a similar pattern as that of CsA-treated positive control group. Levels of mRNAs encoding inflammatory cytokines IL-5, IL-13, $TNF-{\alpha}$, and eotaxin were determined by RT-PCR in the lung tissue and showed decreases in CHS-treated group to the similar levels of CsA-treated control group, Histamine level in the serum was significantly lower in CHS-treated group than asthma-induced control group. Both haematoxylin and eosin staining and Masson's trichrome staining results showed decreased number of inflammatory cells, reduced immune cell infiltration, and normalized epithelial cell layering in the bronchial tissue of CHS-treated mouse group. Thus, the present findings suggest that CHS may be useful for protecting bronchial tissues from consistent inflammatory damages that occur in asthma patients.

  • 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.
