bronchoconstriction

 [brong″ko-kon-strik´shun]
narrowing of a bronchus as a result of smooth muscle contraction, as in asthma.

bron·cho·con·stric·tion

(brong'kō-kon-strik'shŭn),
Reduction in the caliber of a bronchus or bronchi, usually referring to a dynamic process as in asthma and emphysema, rather than a fixed constriction (the latter is a bronchial stenosis). Compare: bronchospasm.

bronchoconstriction

The narrowing of a bronchus due to the contraction of the surrounding smooth muscle, which may be caused by either histaminic-H1/2 or muscarinic (M1/2/3) receptors.

bronchoconstriction

Narrowing of a bronchus, bronchostenosis

bron·cho·con·stric·tion

(brong'kō-kŏn-strik'shŭn)
Constriction of the bronchi.

bronchoconstriction

Contraction of the circular muscles in the walls of the bronchi, so narrowing the bore of the tubes and restricting air entry. See also BRONCHOSPASM.

bron·cho·con·stric·tion

(brong'kō-kŏn-strik'shŭn)
Constriction of the bronchi.

Most substernal goiters can be managed through a transcervical approach, but a full sternotomy is required when a substernal goiter extending to both sides of the thorax and/or has a larger diameter than the thoracic inlet or when airway constriction is revealed.
The airway constriction in smokers was reversible which was mostly seen for medium and small sized airways.
The device uses thermal energy to reduce the smooth muscle that is responsible for airway constriction occurring in patients with severe asthma.
The sheep model used is naturally sensitive to an antigen derived from the roundworm Ascaris suum, developing asthma-like symptoms (such as airway constriction) when exposed to this antigen.
Treatment for allergies and asthma fall into two categories: those offering quick relief like antihistamines, nasal sprays (corticosteroids), decongestants and inhalers containing beta agonists that can prevent attacks; and long-term medications to reverse inflammation and relieve airway constriction (cromolyn sodium and leukotriene modifiers).
Asthma--a chronic lung disease characterized by airway constriction and inflammation--typically causes symptoms in the chest.
Histamine has long been known as a major activator of airway constriction and inflammation in allergic reactions and asthma.
* Bronchodilator drugs (prescription drugs that relax and open up air passages in the lungs) -- may be prescribed to treat emphysema if there is a tendency toward airway constriction or tightening.
THEOPHYLLINE, one of the most effective asthma drugs, relaxes the muscles around the bronchi and makes these muscles less irritable, preventing airway constriction.
Minoru Fukuda, Ph.D., Professor at Sanford-Burnham said that they have identified a synthetic molecule, a sulfate monosaccharide that inhibits the signal that recruits T-cells to the lungs to start an asthma attack, and the molecule substantially lessened asthma symptoms such as inflammation, mucus production, and airway constriction.
Standard methods of diagnosing and monitoring of asthma is more traditionally focused on the after-effects, symptoms and airway constriction. NO testing provides a new tool for assessing the level of inflammation that was not possible with traditional testing.
