Nitric oxide (NO) is present at higher concentrations in the nasal cavity than in the lower airway, and at even higher concentrations within the paranasal sinuses proper. When the paranasal sinus ostia are patent, acoustic activity produced by vocali

The revised National Ambient Air Quality Standards for PM include fine particulate standards based upon mass measurements of PM2.5. It is possible in arid and semi-arid regions to observe significant coarse mode intrusion in the PM2.5 measurement. In

To evaluate the pulmonary effects of varying doses of sulfuric acid, adolescent subjects with asthma were exposed to 35 or 70 micrograms/m3 sulfuric acid for 45 or 90 min. Exposure was carried out during intermittent moderate exercise. The pulmonary

Adolescent asthmatic subjects have been shown to be much more sensitive than healthy adolescents to the inhaled effects of sulfur dioxide. To test whether similar adolescent asthmatics are more sensitive to other common ambient air pollutants, 10 hea

The mechanism(s) of adverse reactions to sulfites remains unclear. To determine whether mast cell degranulation is involved in sulfite sensitivity, we performed single-blind, placebo-controlled oral aqueous challenges with potassium metabisulfite in

The aim of this project was to investigate whether or not well characterized groups of healthy adolescents and adolescents with asthma differed in their sensitivity to ozone and nitrogen dioxide at near ambient concentrations of these pollutants. The

Eight atopic adolescent subjects with exercise-induced bronchospasm were studied to determine whether cromolyn sodium could inhibit or block sulfur dioxide (SO2)-induced bronchoconstriction. Cromolyn or placebo were administered by turboinhaler 20 mi

Ten adolescent subjects with extrinsic asthma and exercise-induced bronchospasm were studied. The subjects were exposed for 30 min at rest followed by 10 min during moderate exercise on a treadmill to either 100 micrograms/m3 sodium chloride (NaCl) o
