  1. Data are presented as mean ± standard deviation.
  2. Pre-MCAO: before MCAO; MCAO 30’: at 30 min after MCAO; Rep 30’: at 30 min after reperfusion. UNICAR, unilateral carotid artery reperfusion; BICAR, bilateral carotid artery reperfusion; Hgb, hemoglobin; MCAO, middle cerebral artery occlusion; MABP, mean arterial blood pressure.
  3. † determined by independent t-test.
