Abstract

Objectives Nebulization is a potential method for delivering therapeutic agents to lung grafts. Recent evidence suggests that nitrite may mitigate ischemia-reperfusion injury via a nitric oxide-dependent pathway.Methods Syngeneic orthotopic left lung transplantation was performed in rats after 7 hours of cold ischemia. Sodium nitrite (3 mg) or phosphate-buffered saline (controls) was delivered before procurement via nebulization.Results Nitrite treatment was associated with better oxygenation, lower peak airway pressure, lower wet/dry ratio, reduced myeloperoxidase level and macrophage infiltration, increased cyclic guanosine monophosphate (cGMP) levels, and decreased levels of interleukin 6, interleukin 1-β, inducible nitric oxide synthase, and intercellular adhesion molecule-1 at 2 hours after reperfusion. Treatment with 2-(4-carboxypheny)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, a nitric oxide scavenger, reversed the beneficial effects of nitrite and decreased cGMP concentration in grafts. A dose-response curve of nitrite was performed at the following doses: 0.3 mg (N0.1), 3.0 mg (N1.0), 5.25 mg (N1.75), 7.5 mg (N2.5), and 15.0 mg (N5.0). All treatments, excluding N1.0, resulted in poorer oxygenation, higher peak airway pressures, and higher wet/dry ratio. Higher dosage groups (N1.75, N2.5, and N5.0) exhibited positive immunostaining of nitrotyrosine and increased the intensity of nitrotyrosine in immunoblotting.Conclusions These data suggest that nebulized nitrite limits lung ischemia-reperfusion injury and may prove a clinically useful strategy but requires appropriate dosing to limit oxidative injury at high doses.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
