Neutrophil infiltration is elevated 72(ICH) in ventricle, cortex, and hippocampus.

<p>Staining for myeloperoxidase (MPO) revealed neutrophil infiltration in the brain regions around the lateral ventricles 72 h after intraventricular hemorrhage (IVH; A) and in the perihematomal regions of the frontal cortex (B) and hippocampus (C) 72 h after cerebral ICH (c-ICH) and hippocampal ICH (h-ICH), respectively. Quantification analysis showed that the number of MPO-positive cells in the IVH, c-ICH, and h-ICH groups was significantly greater than that in the respective sham groups (n = 5 mice per group). Scale bar = 10 µm. Values are means ± SD; **<i>p</i><0.01, t-test.
