The signal intensity decrease of the RMS.

Follow-up	Targeted group	Nontargeted group	Medium alone
	(n = 8)	(n = 8)	(n = 8)
0 d	0.140 ± 0.024	0.156 ± 0.029	0.134 ± 0.030
1 d	0.463 ± 0.032	0.160 ± 0.031	0.155 ± 0.032
3 d	0.328 ± 0.057	0.145 ± 0.029	0.122 ± 0.025
7 d	0.237 ± 0.025	0.109 ± 0.031	0.140 ± 0.024
10 d	0.182 ± 0.028	0.118 ± 0.041	0.126 ± 0.021

Note. There were 8 animals yielding complete data in the animals injected with anti-CD15-SPIONs or nontargeted SPIONs or medium alone. The signal intensity decrease of the RMS was normalized to the contralateral normal brain parenchyma.
