Bronchial hyperresponsiveness (BHR) and physical activity

Physical activity and bronchial hyperresponsiveness: European Community Respiratory Health Survey II.

BACKGROUND Identification of the risk factors for bronchial hyperresponsiveness (BHR) would increase the understanding of the causes of asthma. The relationship between physical activity and BHR in men and women aged 28.0-56.5 years randomly selected from 24 centres in 11 countries participating in the European Community Respiratory Health Survey II was investigated. METHODS 5158 subjects ans...

Allergen-induced Bronchial Hyperresponsiveness

Bradykinin (BK) is a peptide mediator generated at sites of inflammation and its effects are mediated through constitutively expressed B 2 receptor or through induction of B 1 receptors. We examined the role of these receptors in bronchial hyperresponsiveness (BHR). Brown-Norway rats sensitized with ovalbumin (OA) and Al(OH) 3 intraperitoneally, were exposed 3 wk later to either saline or OA ae...

Bronchial Hyperresponsiveness in Asthma*

Measurement ofnonspecific bronchial hyperresponsiveness remains largely a research tool in asthma, and its usefulness in the assessment and management of asthma is poorly defined. We StUdied the relationship of bronchial hyperresponsiveness to the clinical severity of asthma in 54 asthmatic subjects. In order to find out whether measurement of bronchial hyperresponsiveness could be used to pred...
