The aim of the study was to investigate whether measurement of nitric oxide in exhaled air could be used for assessing the effects of irritants on the respiratory system, in this case recurrent ozone gassing in an occupational setting. The study population comprised bleachery workers (n=56) from a Swedish pulpmill carrying out ozone-based pulp bleaching since 1992 and controls (n=39). Both grou...
RATIONALE Airway nitric oxide concentrations are reduced in cystic fibrosis (CF). Arginases compete for L-arginine, the substrate of nitric oxide synthesis. OBJECTIVES We hypothesized that increased arginase activity may be one factor contributing to nitric oxide deficiency in CF. MEASUREMENTS We therefore studied sputum arginase activity, exhaled nitric oxide, and pulmonary function in pat...
The aim of this study was to quantify lung oxidative stress in patients with asthma and chronic obstructive pulmonary disease by measuring levels of exhaled carbon monoxide and nitric oxide. Levels of exhaled carbon monoxide, nitric oxide were evaluated in exhaled air of asthma and COPD patients. Moreover, correlation of CO and NO concentrations with degree of airflow obstruction (FEV1% predict...
