Enhancing Nitric Oxide Bioavailability via Exogen Nitric Oxide Synthase and L-Arginine Attenuates Ischemia-Reperfusion-Induced Microcirculatory Alterations

摘要

Background: Nitric oxide (NO) is an important cytoprotective agent against ischemia and reperfusion injury (TRT). Enhancing NO bioavailability via exogen NO synthases (NOSs) and L-arginine promotes conversation to NO, circumventing the problem of nonfunctioning NOSs under hypoxic and acidic conditions. In this study, the authors evaluated the therapeutic efficacy of endothelial, inducible and neuronal NOS, and L-arginine on reperfusion-induced microcirculatory alterations and hemodynamic adverse effects in the microvasculature of skeletal muscle.
