Hyperreactivity and Bronchial Obstruction
Respiration, 1991The main obstructive components in bronchial asthma and chronic obstructive pulmonary disease (COPD) are discussed. It is underscored that bronchospasm plays a significant role also in COPD, and that it merits specific treatment (beta 2-stimulants, antimuscarinics, theophylline) even when, in some cases, obstruction appears to be 'irreversible'.

Bronchial hyperreactivity is characterized by increased responsiveness of bronchial smooth muscle to non-specific constrictor stimuli. Tests used in assessing airway calibre are influenced by a number of factors and should be regarded as providing a qualitative rather than quantitative index of reactivity.

Hypomagnesemia and bronchial hyperreactivity
Allergy, 1989In a 37‐year‐old woman, a heavy smoker and an alcoholic, bronchial hyperreactivity to histamine (PC20 FEV1 0.8 mg/ml) was related to hypomagnesemia (0.55 mmol/l). After acute magnesium repletion (24 h i.v. infusion MgSO4 6 g, serum magnesium 1.05 mmol/l), histamine PC20 FEV1 increased up to 9.8 mg/ml.

Bronchial hyperreactivity, the abnormal reaction of the airways on non-allergic stimuli, is a feature of patients with chronic nonspecific lung disease. Several underlying mechanisms such as the neurogenic pathways, inflammatory cells and mediators, increased vascular leakage, epithelial damage and pathological changes in airway smooth muscle seem to ...

Respiratory infections and bronchial hyperreactivity
Journal of Allergy and Clinical Immunology, 1988Airway hyperirritability or hyperresponsiveness i a principal characteristic of asthma. The relationship of respiratory infections to either the development or enhancement of airway hyperreactivity poses an important clinical problem and may also provide insight into the pathogenesis of bronchial hyperresponsiveness and, possibly, asthma.

Ozone-Induced Bronchial Hyperreactivity
1996Ozone (03) is a powerful oxidizing agent which is classified as a “secondary air pollutant”. Secondary air pollutants are not emitted into the atmosphere but formed from subsequent atmospheric chemical reactions of primary pollutants (nitrogen dioxide, sulfur dioxide, particles, carbon monoxide, lead).

Cytokines and Bronchial Hyperreactivity
1990Cytokines and interleukins are a potent group of molecules that is primarily involved in maintaining homeostasis. These molecules regulate the growth and function of many cells of the immune system including eosinophils, mast cells/basophils and others.

Bronchial hyperreactivity revisited.
Annals of allergy, asthma & immunology : official publication of the American College of Allergy, Asthma, & Immunology, 1995The purpose of this article is to review bronchial reactivity: how it is detected, what are the clinical and pathologic correlates and what treatment modulates it. Is it a good diagnostic test for a disease such as asthma? Is it a reasonable parameter to follow in assessing disease severity and response to treatment?Recent studies on human subjects in ...
