Measurement of nitric oxide in biological models.
Nitric oxide (NO) is a small, gaseous, paramagnetic radical with a high affinity for interaction with ferrous hemoproteins such as soluble guanylate cyclase and hemoglobin. Interest in NO measurement increased exponentially with the discovery that NO or a related compound is the endothelium-derived relaxing factor (EDRF). In addition to being a potent endogenous vasodilator, NO has a role in in...
متن کاملMeasurement of nasal nitric oxide.
Nasal nitric oxide (nNO) is produced in high quantity in the upper airways. It is thought to be involved in host defence functions and regulation of mucociliary function, and to serve as a biochemical airborne transmitter. The measurement of nNO is easy and non-invasive. It has evolved as a screening test to exclude primary ciliary dyskinesia (PCD) in patients with suggestive symptoms, because ...
متن کاملMeasurement of Renal Vitamin E for Assessment of Iron and Nitric Oxide Interaction in Rats
Oxidative stress has been implicated as an important factor in induction of many disorders such as nephropathy and cancer. Iron by producing hydroxyl radical can cause this kind of stress. On the other hand nitric oxide (NO) when its concentration is high results in oxidative stress. Iron and NO have some interactions in each other function but there is no total agreement on this. For example i...
متن کاملMeasurement of exhaled nitric oxide in man.
BACKGROUND Nitric oxide is released from pulmonary endothelial cells and contributes to the low pulmonary vascular resistance. The resistance pulmonary arteries are in close anatomical proximity to membranous airways, so it is likely that some pulmonary endothelial nitric oxide will enter the airspace to allow its measurement in the exhaled breath. METHODS Exhaled air was collected from a sin...
