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.

Intraoperative delivery of salbutamol (${\beta}_2$ agonist) through a breathing circuit may be performed in asthma patient. A 28-year-old woman with a history of asthma was diagnosed with chronic sinusitis and bilateral nasal polyps, and an endoscopic sinus surgery was performed. The patient was recommended salbutamol nebulization every 4 hours during the perioperative period because of the risk of asthma attack. At the end of the operation, when salbutamol was sprayed through the tube before extubation and the connector tip went inside the tube during injection. The patient was immediately referred to the pulmonary medicine department for bronchoscopy, where the foreign body was removed safely without any complications. When general anesthesia is performed on a patient who usually uses an inhaler for asthma, caution is required because the tip that connects the inhaler and the breathing circuit can aspirate into the endotracheal tube and enter the lungs when applying the inhaler before waking up the patient.

Matrix metalloproteinase (MMP)-9 plays an important role in the pathogenesis of bronchial asthma. Neovastat, having significant antitumor and antimetastatic properties, is classified as a naturally occurring multifunctional antiangiogenic agent. We evaluated the therapeutic effect of Neovastat on airway inflammation in a mouse model of asthma. BALB/c mice were immunized subcutaneously with ovalbumin (OVA) on days 0, 7, 14, and 21 and challenged with inhaled OVA on days 26, 29, and 31. Neovastat was administrated by gavage (5 mg/kg body weight) three times with 12 h intervals, beginning 30 min before OVA inhalation. On day 32, mice were challenged with inhaled methacholine, and enhanced pause (Penh) was measured as an index of airway hyperresponsiveness. The severity of airway inflammation was determined by differential cell count of bronchoalveolar lavage (BAL) fluid. The MMP-9 concentration in BAL fluid samples was measured by ELISA, and MMP-9 activity was measured by zymography. The untreated asthma group showed an increased inflammatory cell count in BAL fluid and Penh value compared with the normal control group. Mice treated with Neovastat had significantly reduced Penh values and inflammatory cell counts in BAL fluid compared with untreated asthmatic mice. Furthermore, mice treated with Neovastat showed significantly reduced MMP-9 concentrations and activity in BAL fluid. These results demonstrate that Neovastat might have new therapeutic potential for airway asthmatic inflammation.

Allergic asthma, is a common chronic inflammatory disease of the airway presenting with airway hyperresponsiveness and airway remodelling. T helper cells-derived cytokines are critically associated with asthma pathogenesis. Janus kinase-signal transduction and activation of transcription (JAK/STAT) signaling is found to be involved in asthma. Magnolol is a plant-derived bioactive compound with several pharmacological effects. The study aimed to assess the effects of magnolol in ovalbumin (OVA)-induced asthmatic model. BALB/c mice were sensitized and challenged with OVA. Magnolol (12.5, 25, or 50 mg/kg body weight) was administered to separate groups of animals. Dexamethasone was used as the positive control. Cellular infiltration into the bronchoalveolar lavage fluid (BALF) were reduced on magnolol treatment. The levels of Th2 and Th17 cytokines were reduced with noticeably raised levels of interferon gamma. Lung function was improved effectively along with restoration of bronchial tissue architecture. OVA-specific immunoglobulin E levels in serum and BALF were decreased by magnolol. Magnolol reduced Th17 cell population and effectively modulated the JAK-STAT and Notch 1 signaling. The results suggest the promising use of magnolol in therapy for allergic asthma.

Allergy has a born predominant cause of atopy in body and react oversenstively several meterial. The cause of allergy are tick, house dust, egg, milk, bean, cosmetics, virus, bacteria, flesh and meat in Western medicine. While, Oriental medicine did not have an application on the allergy, but recognized that allergy is connected with fetal toxicosis, heat-syndrome in new born, syndrome characterized by dyspnea, sneezing, stuffy nose, nasal discharge and phlegm. Therefor, We knowed method of medical treatment following cause of disease and pathogenesis against allergy. Allergic disease(atopic dermatitis, bronchial asthma, rhinitis) were related with lung, spleen, kidney. To prevent allergic disease in born, Oriental medicine taked a serious view of fetal education. In Western medicine, The cause of allergy applied to exopathogen of Oriental medicine. In Oriental medicine, Treatment of allergy used generally strengthening the body resistance to eliminate pathogenic factors.

Purpose: In this study, symptom experience and quality of life(QoL) in patients with Bronchial asthma(BA) and Bronchiectasis(BRC) were examined to develop nursing strategies. Method: Data collection was done with 61 outpatients with BA and 43 outpatients with BRC in January and February, 2001. Data analyses were performed using SPSS Win 8.0. Result: The mean scores of symptom experience were 11.3 and 10.8 in patients with BA and BRC, respectively. The mean score of QoL was 18.0 in patients with BA and 19.2 in patients with BRC. There were statistically significant differences in the score of the symptom experience according to sex and occupation in patients with BA, and to the religion and occupation in patients with BRC. The mean score of QoL had significant difference according to the income in patients with BA, but had no significant differences in patients with BRC. The score of QoL had significantly correlated with the degree of symptom experience in patients with BA(p=.000) and with BRC(p=.022). Conclusion: The degree of symptom experience negatively correlated with QoL. Therefore, symptoms experienced by patients should be considered in development of nursing strategies for patients with BA and BRC.
