Physiology of airway mucus secretion and pathophysiology of hypersecretion.
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...
متن کاملRhinovirus infection induces mucus hypersecretion.
Rhinorrhea is a prominent symptom of the common cold. Although increases in vascular permeability and serous cell secretion have been demonstrated in human nasal mucus during active rhinovirus infections, changes in mucin constituents have not been quantified. Nonallergic ( n= 48) and asymptomatic allergic rhinitis ( n = 32) subjects were inoculated with rhinovirus type hanks before the spring ...
متن کاملAirway mucus.
Hypersecretion of mucus is a cardinal sign of airways inflammation. Normally, secretion of mucus is designed to protect the respiratory portion of the lung from injury, but in disease its chronic overproduction in large airways (bronchi) and its appearance in small conducting airways (bronchioles) may be detrimental. Its relevance to patient discomfort and infection is generally accepted, but i...
متن کاملEBM84 attenuates airway inflammation and mucus hypersecretion in an ovalbumin-induced murine model of asthma.
EBM84 is a traditional herbal medicine and a combination of extracts obtained from Pinellia ternata and Zingiber officinale. It is traditionally used to treat vomiting, nausea, sputum and gastrointestinal disorders, and functions is an effective expectorant. In this study, we evaluated the protective effects of EBM84 on asthmatic responses, particularly mucus hypersecretion in an ovalbumin (OVA...
متن کاملAzithromycin Inhibits Mucus Hypersecretion from Airway Epithelial Cells
To examine the in vivo effects of the 15-member macrolide, azithromycin (AZM), on mucus hypersecretion, we induced hypertrophic and metaplastic changes of goblet cells in rat nasal epithelium by intranasal instillation of ovalbumin (OVA) in OVA-sensitized rats, or by intranasal lipopolysaccharides (LPS) instillation. Oral administration of AZM (5-10 mg/kg) or clarithromycin (CAM, 5-10 mg/kg) si...
