['Given that reliable markers for early ischemic brain damage are lacking, we set out to test whether pimonidazole can be used as a reliable tool in the quantification of hypoxic insults, at early time points following experimental stroke.', 'We have used semi-quantitative Western blotting detection of pimonidazole adducts in a rat model of reversible middle cerebral artery occlusion (MCAO), treated with remote post-conditioning.', 'First, we demonstrated that a linear relationship exist between pimonidazole binding in the ischemic hemisphere and duration of ischemia, in animals subjected to 5, 15, 30, or 60 minutes of occlusion followed by 120 minutes of reflow. Then we showed a significant reduction in pimonidazole binding in the infarcted hemisphere, when rats with 60 minutes of MCAO, immediately after establishment of cerebral reflow, had 3×15 minutes intermittent hind limb ischemia followed by 24-hour survival. We analysed the middle cerebral arteries from animals with 60 minutes of MCAO and early remote post-conditioning, followed by 30 minutes, 24, or 48 hours of reflow. At 24 hours of reflow increases in phosphorylated protein kinase C-alpha with concomitantly increased levels of p38 phosphorylation were observed.'] Does remote post-conditioning reduce hypoxic damage early after experimental stroke?
