  • The mast cell-mediated immediate-type allergic reaction is involved in many allergic diseases such as asthma, allergic rhinitis, and sinusitis. The discovery of drugs for the treatment of mast cell-mediated immediate-type allergic diseases is a very important subject in human health. In this study, we investigated the effect of small black soybean (Glycine max Merr.) (Leguminosae) on mast cell-mediated allergic reaction and pro-inflammatory cytokine secretion. Small black soybean (SBS) inhibited compound 48/80-induced systemic reaction. SBS attenuated immunoglobulin (Ig) E-mediated local allergic reaction. In addition, SBS decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-8 secretion in human mast cells. These results indicate that SBS may be beneficial in the treatment of mast cell-mediated immediate-type allergic reactions.

  • Hesperidin, a member of the flavanone group of flavonoids, can be isolated in large amounts from the rinds of some citrus species [e.g., Citrus aurantium L. (bitter orange), Citrus sinensis L. (sweet orange) and Citrus unshiu Marcov. (satsuma mandarin)], and has been reported to have anticarcinogenic, antihypotensive and antimicrobial properties. Despite the efficacy of these polyphenolic compounds as immune modulators, the effects of the flavonoids are poorly understood about allergic effect. In this study, we investigated whether hesperidin could influence on Th1 and Th2 balance. Allergic reactions included an increase in the number of eosinophils in bronchoalveolar lavage (BAL) fluid, an increase in inflammatory cell infiltration into the lung tissue around blood vessels and airways, airway luminal narrowing, the development of airway hyper-responsiveness (AHR). The administration of hesperidin before the last airway OVA challenge resulted in a significant inhibition of all asthmatic reactions. Accordingly, this study may provide evidence that hesperidin plays a critical role in the amelioration of the pathogenetic process of asthma in mice. These findings provide new insight into the immunopharmacological role of hesperidin in terms of its effects in a murine model of asthma, and also broaden current perspectives in our understanding of the immunopharmacological functions of hesperidin.

  • Fructus of Rubus coreanus $M_{IQ.}$. (FRCM) has been used for stuttering urination, prostate gland disease, and impotence in Korean traditional medicine. Water extract of FRCM (WFRCM) treatment significantly attenuated airway hyperreactivity (AHR). Airway recruitment of leukocytes and eosinophils was also markedly reduced by WFRCM administration, suggesting that WFRCM can alleviate the airway inflammation. However, the level of cytokine (IL-4, IL-5, and IL-13) in bronchoalveolar lavage fluid (BALF) and lung was not different compared with positive control. WFRCM reduced the number of draining lymph node cells during OVA-induced allergic asthma. I further examined transcription level of cytokine in lung. WFRCM treatment reduced IL-4 and IL-13 mRNA in lung and inhibited IgE and IgG1 but not IgG2a. My data suggest that WFRCM attenuates OVA-induced allergic asthma through inhibition of Th2 cell response.

  • Objectives: Allergic asthma generally presents with symptoms of wheezing, coughing, breathlessness, and airway inflammation. Seonpyejeongcheon-tang (SJT) consists of 12 herbs. It originated from Jeong-cheon-tang (JT), also known as Ding-chuan-tang, composed of 7 herbs, in She-sheng-zhong-miao-fang. This study aimed to evaluate the effects of local delivery of SJT via inhalable microparticles in an asthma mouse model. Methods: Microparticles containing SJT were produced by spray-drying with leucine as an excipient. SJT microparticles were evaluated with respect to their aerodynamic properties, in vitro cytotoxicity, in vivo toxicity, and therapeutic effects on ovalbumin (OVA)-induced asthma in comparison with orally-administered SJT. Results: SJT microparticles provided desirable aerodynamic properties (fine particle fraction of $48.9%{\pm}6.4%$ and mass median aerodynamic diameter of $3.7{\pm}0.3{\mu}m$). SJT microparticles did not show any cytotoxicity against RAW 264.7 macrophages at concentrations of 0.01 - 3 mg/mL. Inhaled SJT microparticles decreased the levels of IL-4, IL-5, IL-13, IL-17A, eotaxin and OVA-IgE in bronchoalveolar lavage fluid (BALF) in mice with OVA-induced asthma. These effects were verified by histological evaluation of the levels of infiltration of inflammatory cells and collagen, destructions of alveoli and bronchioles, and hyperplasia of goblet cells in lung tissues. The effects of SJT microparticles in the asthma model were equivalent to those of orally-administered SJT extract. Conclusion: This study suggests that SJT is a promising agent for inhalation therapy for patients with asthma.

  • Purpose: A high level of air pollutants can increase the number of patients with allergy-related diseases such as asthma and allergic rhinitis (AR). To analyze the association between air pollution and allergic disease, we investigated 2 areas in Korea: Incheon, an industrial area, and Jeju, a non-industrialized area. Methods: Second grade students at elementary schools (11 schools in Incheon and 45 schools in Jeju) were examined in a cross-sectional study. A questionnaire was used and a skin prick test was performed. The levels of $NO_2$, $CO_2$, $O_3$, particulate matter (PM) $PM_{10/2.5}$, formaldehyde, tVOCs, and dust mites in the classrooms and grounds were determined. Results: The levels of outdoor CO, $PM_{10}$, and $PM_{2.5}$ were significantly higher in Incheon (P<0.01). The levels of indoor CO, $CO_2$, $PM_{10}$, $PM_{2.5}$ were significantly higher in Incheon (P<0.01). The prevalence rates of AR symptoms at any time, AR symptoms during the last 12 months, diagnosis of rhinitis at any time, and AR treatment during the last 12 months were significantly higher in Incheon (P<0.01). The prevalence rate of wheezing or whistling at any time, and wheezing during the last 12 months were significantly higher in Incheon (P<0.01). Conclusion: We found that the children living in Incheon, which was more polluted than Jeju, had a higher rate of AR and asthma symptoms compared to children in Jeju. To determine the effect of air pollution on the development of the AR and asthma, further studies are needed.

  • Objectives: This study aims to identify the influential factors on the pulmonary function of targeted general residents in the areas surrounding Gwangyang Steel Mill. Methods: An PFT (Pulmonary Function Test) was conducted from May 2007 to November 2007 on 974 target residents (438 male, 536 female), including an exposed group (674 people) who resided within a radius of 5 km from Gwangyang Steel Mill in Gwangyang-si, Jeollanam-do and a control group (300 people) who resided outside a radius of 15 km. A survey related to personal characteristics, life habits, respiratory diseases and allergic symptoms, medical histories and living environments of the residents was also conducted to identify influential factors on pulmonary function. Results: As %$FEV_1$ and %FVC of the exposed group are 99.17% and 96.98%, respectively, and those of the control group are 105.47% and 101.91%, respectively, with the PFT values of the exposed group being lower than those of the control group (p<0.001), it turns out that the pollution in the industrial complex is likely to trigger a reduction in the pulmonary function of local residents. The odds ratio analysis result for asthma diagnosis history indicates that the odds ratios tend to be higher among surveyed residents who are living near above-average traffic volumes and are using beds, where it is statistically meaningful that especially the odds ratios are higher if the residences are closer to roads (p<0.01, CI=1.12-4.52). The factors that affect the FEV1 are identified as smoking, passive smoking, asthma diagnosis history, nasal congestion symptoms and allergic eye disease ($R^2$=0.154, p<0.001). The factors that affect the FVC are identified as smoking, passive smoking, asthma diagnosis history and allergic coryza ($R^2$=0.158, p<0.001). In addition, the analysis result for the relevance of air pollution levels to pulmonary function ($FEV_1$, FVC) shows that FEV1 and FVC tend to decrease as the concentration of $O_3$ increases. Conclusions: We believe that this study may provide preliminary data for the development of preventive measures for health effects on the residents and environmental health control measures for environmental pollution in the industrial complex area.

  • Objectives : The root of Codonopsis pilosula (Fr.) Nannf. (Codonopsis Pilosulae Radix) has been traditionally used as a oriental medicine with an anti-thrombotic, antidiabetic, anticancer, and anti-gastric ulcer effects and immunological adjuvant. In this study, we investigated the effect of 70% ethanol extract of Codonopsis Pilosulae Radix (CPR-E) on ovalbumin (OVA)-induced allergic responses in mice. Methods : Mice were sensitized (1, 8, and 15 days) with OVA and airway challenged(22, 24, 26, 28, and 30 days) to induced allergic responses. CPR-E extract at doses of 50 and 100 mg/kg/body weight was orally administered from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and Th1/Th2 cytokines such as IFN-${\gamma}$ and IL-4 were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : CPR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-${\gamma}$. Based on H&E staining, CPR-E extract inhibited the infiltration of inflammatory cells into lung tissues with histological changes. Conclusions : These results indicate that CPR-E extract has anti-inflammatory and anti-allergic responses through regulating the cytokine balance, suggesting that the extract may be useful for the treatment of allergic inflammatory diseases such as bronchial asthma and allergic rhinitis.

  • 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.
