Fig. 1. FACS analysis of macrophages 1 week after spinal cord injury. M1 macrophages were iNOS+&ED1+ cells (A) and M2 macrophages were CD206+&ED1+ cells (B). There were no significant difference in the number of M1 and M2 macrophages between agmatine treatment group (Agm, n=3) and experimental control group (EC, n=3, C&D). Median fluorescence intensity (MFI) of iNOS was decreased with agmatine treatment (E) and MFI of CD206 was increased in agmatine treatment group (F) without significance.
