Figure 5: Microglia/macrophage activation 10 days after ICH. (A) Representative images showed ED-1 positive cells at the edge of hematoma. (B) Representative images showed ED-1 positive cells in the lesion core. Scale bar = 100 μm. (C) Quantitative analysis of ED-1 positive cells at the edge of the hematoma 10 days after ICH in cells/mm2. n = 4 for the ICH only group, n = 3 for the Asp group, n = 3 for the saline group, and n = 5 for the SAP group. *P < 0.05 versus the other groups. Asp: aspiration only.
