airway hyper-reactivity

airway hyper-reactivity

The strong tendency, in people with ASTHMA, for the air passages to undergo a sudden and abnormal degree of narrowing under the influence of various stimuli such as inhaled pollen grains or house mite droppings, changes of temperature, emotional upset or exercise.

These measures of asthma control permitted later calculation of what is called diurnal peak flow variability (dPFV), an indicator of airway hyper-reactivity.
Objective: To evaluate and compare the protective effects of salbutamol and montelukast in amelioration of insulin induced airway hyper-reactivity on isolated tracheal smooth muscle of guinea pig in vitro.
Asthma is a chronic inflammatory disease of airways characterized by chronic inflammation, airway hyper-reactivity, and by symptoms of coughing, wheezing and chest tightness.
AbstractObjective: To study the magnitude of insulin-mediated airway hyper-reactivity and to explore the protective effects of salbutamol in inhibiting the insulin-induced airway hyper-responsiveness on tracheal smooth muscle of guinea pigs in vitro.
2] Several clinical studies have demonstrated that inhaled corticosteroid (ICS) therapy improves lung function, reduces airway hyper-reactivity [3], and mediates a marked reduction in inflammatory mediators in the bronchial epithelium and sub-mucosa [4].
1], but produced significant improvements in peak expiratory flow, symptoms, quality of life, and airway hyper-reactivity.
Dietary magnesium, lung function, wheezing, and airway hyper-reactivity in a random adult population sample.
Th2 cells influence the asthmatic response by secreting substances which recruit inflammatory cells into the lungs, increase mucus production in the airways and cause airway hyper-reactivity.
16) It is additionally hypothesized that a high magnesium diet is directly related to healthy lung function and a reduced risk of airway hyper-reactivity and wheezing.
When untreated mice inhaled ragweed extract, their lungs suffered an influx of eosinophils (inflammation-inducing white blood cells), a jump in inflammatory signaling molecules, a buildup of mucin (a protein component of mucus) and an increase in airway hyper-reactivity (the tendency of air passages to suddenly constrict under stress).
Magnesium intake is inversely related to the risk of airway hyper-reactivity and wheezing.
Asthma is a chronic inflammatory disease with reversible airway obstruction and nonspecific airway hyper-reactivity.
