  Background: There are conflicting reports concerning the role of nitric oxide (NO) and oxidative stress in brain ischemic damage. In the present study, a nanomedical approach was utilized to elucidate the role of NO and peroxynitrite (ONOO - ) imbalance in ischemic stroke. Methods: Nanosensors (diameter ~ 200 nm, detection limit of 10-9 molL-1, response time ~10 μs) were used to monitor in situ the concentration of NO and ONOO - . Adult male Sprague Dawley rats were given permanent middle cerebral artery occlusion (pMCAO) for 3 h, 12 h or 24 h. [NO]/[ONOO - ] was measured in striatum, along with, constitutive nitric oxide synthase (cNOS) enzymes and heme oxygenase-1 (HO-1) expression and infarct volume. The [NO]/[ONOO - ] was also monitored in pre-treated animals with simvastatin and atorvastatin in the presence of the cNOS inhibitor L-NAME. The effect of modulators of.. View More»
