Brief Summary:
This pilot study will measure the baseline levels and the intra- and inter-subject variability of exhaled (alveolar and bronchial) and nasal NO in smoking subjects with mild and moderate COPD on or off steroid treatment, smoking healthy volunteers and non-smoking mild asthmatics off steroids, using multiple exhalation flow rates.

Detailed Description:
n addition, exploratory markers of iNOS activity (eg. 3-nitrotyrosine, nitrite, nitrate and 3-nitro-4-hydoxyphenylacetic acid) in blood, sputum, urine and exhaled breath condensate will be evaluated. We will also evaluate exhaled and nasal NO in a population of mild asthmatics in order to obtain baseline and variability data for future clinical studies involving asthmatic subjects.
