Introduction Bronchial asthma is a chronic inflammatory condition involving a variety of cells including eosinophils, mast cells, T lymphocytes, neutrophils, and epithelial cells of the airway, as well as cellular elements, which gives rise to the increase of airway hyper-reactivity. Extensive changeable and reversible ventilatior restriction is common and can cause recurrent tachypnea, feeling of out of breath, and coughing. The symptoms are more
