Brief Summary
The primary aim of this study is to investigate the effects of oral and inhaled administration of L-arginine and of inhaled aminoguanidine on bronchial and alveolar exhaled NO and NO metabolites in exhaled breath condensate, induced sputum, nasal lavage and mouth wash fluid in healthy non-smokers, current smokers and patients with COPD.
