When an asthmatic is near to or comes in contact with a trigger, an asthma episode (asthmatic attack) may start. The airways and their linings may become swollen, produce mucus, and tighten up. The muscles around the airways can also tighten, making the airways even narrower. As the ...
Sputum eosinophils. This test looks for high levels of white blood cells (eosinophils) in the mix of saliva and mucus (sputum) that comes out when you cough. Asthma Treatment Manyasthma treatmentscan ease your symptoms. Your doctor will work with you to make an asthma action plan that will ...
When the inflammation is "triggered" by any number of external and internal factors, the walls of the passages swell, and the openings fill with mucus. Muscles within the breathing passages contract (bronchospasm), causing even further narrowing of the airways. This narrowing makes it difficult fo...

Improves sputum depletion, stimulates the production of mucus, activates the functions of the epithelium of the bronchi. It inhibits the ejection of mediators of inflammation from mast cells and basophils, in particular anti- IgE- induced release of histamine, eliminates antigen-dependentsuppreβion of...

IL-3, IL-4, and granulocyte-macrophage colony-stimulating factor ( GM-CSF ) prolong eosinophil survival. IL-4 also helps with T-cell differentiation and IgE production. IL-13 increases mucus glands, airway fibrosis , and remodeling. Eosinophils (the most prominent cells) increase the release of...
