Figure 1

Mean of normalized amount of infiltrating neutrophils according to survival time. Duration of occlusion has an influence on the temporal profile of neutrophilic infiltration, suggesting that 120 minutes of MCAO results in an early massive influx of neutrophil granulocytes compared to the shorter occlusion times. Data are also presented in Table 2. MCAO, middle cerebral artery occlusion; pMCAO, permanent middle cerebral artery occlusion.
