The effect of alcohol ingestion on exhaled nitric oxide.
The concentration of nitric oxide (NO) is increased in the exhaled air of patients with inflammatory lung diseases, including asthma, possibly reflecting cytokine-mediated chronic airway inflammation. Endogenous NO is generated from L-arginine by the action of several types of NO synthase (NOS). NOS have structural similarities with cytochrome P450 reductases. Alcohol decreases exhaled NO in an...
متن کاملThe effect of fiberoptic bronchoscopy on exhaled nitric oxide.
Nitric oxide has been extensively studied as a noninvasive marker of airway inflammation. Assuming that bronchoscopy can produce not only systemic but also local inflammatory response, we hypothesized that bronchofiberoscopy can be responsible for an increase in nitric oxide synthesis with resulting increase in fractional concentration of exhaled nitric oxide (FE(NO)). Fifty five subjects (F/M-...
متن کاملThe effect of posture-induced changes in peripheral nitric oxide uptake on exhaled nitric oxide.
Airway and alveolar NO contributions to exhaled NO are being extracted from exhaled NO measurements performed at different flow rates. To test the robustness of this method and the validity of the underlying model, we deliberately induced a change in NO uptake in the peripheral lung compartment by changing body posture between supine and prone. In 10 normal subjects, we measured exhaled NO at t...
متن کاملEffect of airways constriction on exhaled nitric oxide.
While airway constriction has been shown to affect exhaled nitric oxide (NO), the mechanisms and location of constricted airways most likely to affect exhaled NO remain obscure. We studied the effects of histamine-induced airway constriction and ventilation heterogeneity on exhaled NO at 50 ml/s (Fe(NO,50)) and combined this with model simulations of Fe(NO,50) changes due to constriction of air...
متن کاملEffect of heterogeneous ventilation and nitric oxide production on exhaled nitric oxide profiles.
Elevated exhaled nitric oxide (NO) in the breath of asthmatic subjects is thought to be a noninvasive marker of lung inflammation. Asthma is also characterized by heterogeneous bronchoconstriction and inflammation, which impact the spatial distribution of ventilation in the lungs. Since exhaled NO arises from both airway and alveolar regions, and its level in exhaled breath depends strongly on ...
