phosphodiesterases (pde) hydrolyse intracellular camp and cgmp to inactive 5’ monophosphates. decreased level of camp is involved in the pathogenesis of asthma. we and others have shown that phosphodiesterases were upregulated in the lung of allergic rats, and bacilli calmette-guérin (bcg) induced the production of camp in vitro. however, it is unclear how bcg’s effect asthma and whether...
BACKGROUND Eosinophilic inflammation of the airway is usually associated with airway hyper-responsiveness in bronchial asthma. However, there is a small group of patients which has the eosinophilic inflammation in the bronchial tree with normal spirometry and no evidence of airway hyper-responsiveness, which was named eosinophilic bronchitis. The objectives of this study are 1) to investigate t...
Agastachis Herba is one of the well-known medicinal herbs in Korean traditional medicine. This study was taken up to examine the beneficial effects of Agastachis Herba on a mice model of asthma. BALB/c mice were sensitized and challenged with ovalbumin to produce a murine model of asthma. Methanol extracts of Agastachis Herba were orally administered to the ovalbumin-induced asthmatic mice. The...
Bronchial asthma is a disease characterized by the condition of airway hyper-responsiveness, which serves to produce narrowing of the airway secondary to airway inflammation and/or various spasm-inducing stimulus. Nonspecific bronchoprovocation testing is an important method implemented for the purpose of diagnosing asthma; this test measures the actual degree of airway hyper-responsiveness and...
