IntroductIon Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death in the developed world and associated with a high individual and socioeconomic burden.[1] It is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to(More)
BACKGROUND Exhaled nitric oxide (NO) is a noninvasive biomarker of airway inflammation in pulmonary diseases. Hydrogen sulfide (H2S), as the third member of the gasotransmitter family, is involved in the pathophysiological process in lung diseases. H2S also exists in exhaled breath and can be sampled non-invasively. The study investigated the level of(More)
Oxidative stress and inflammation play crucial role in the pathogenesis of chronic obstructive pulmonary disease (COPD). Most patients with COPD show a poor response to corticosteroids. Hydrogen sulfide (H2S ) has been implicated in the pathogenesis of COPD, but its expression and effects in lung tissue from COPD patients are not clear. In peripheral lung(More)
