The parasympathetic vagus nerve supplies the heart and lung. Parasympathetic activity modifies rate force of contraction in Airway bronchial smooth muscle constriction hypersecretion mucus lungs. There is a link between these two components. Hence this study designed to find association Spectral analysis variability pulmonary function tests asthma patients. In study, 30 asthmatic patients were ...

The epithelial cells lining the airways serve protective functions. The ‘‘barrier function’’ of the epithelium protects the individual from damage by inhaled irritants. The epithelium produces mucins which become hydrated and form a viscoelastic gel which spreads over the epithelial surface. In healthy individuals inhaled foreign materials become entrapped in the mucus and are cleared by mucoci...

Mucus secretion is the first-line defense against the barrage of irritants that inhalation of approximately 500 L of air an hour brings into the lungs. The inhaled soot, dust, microbes, and gases can all damage the airway epithelium. Consequently, mucus secretion is extremely rapid, occurring in tens of milliseconds. In addition, mucus is held in cytoplasmic granules in a highly condensed state...

Inflammatory diseases of the respiratory system such as rhinosinusitis, chronic obstructive pulmonary disease, or bronchial asthma are strongly associated with overproduction and hypersecretion of mucus lining the epithelial airway surface. 1,8-cineol, the active ingredient of the pharmaceutical drug Soledum, is commonly applied for treating such inflammatory airway diseases. However, its poten...

BACKGROUND Therapeutic intervention in the pathophysiology of airway mucus hypersecretion is clinically important. Several types of drugs are available with different possible modes of action. We examined the effects of guaifenesin (GGE), N-acetylcysteine (NAC) and ambroxol (Amb) on differentiated human airway epithelial cells stimulated with IL-13 to produce additional MUC5AC. METHODS After ...
