Images show myeloperoxidase (MPO)-specific MRI of treatment effect.
A, Representative three-dimensional maps of
90-minute
bis-5-hydroxytryptamide-diethylenetriaminepentaacetate
gadolinium (hereafter, MPO-Gd) contrast-to-noise ratios (CNRs) over
entire brain (axial view) show overall disease burden for each group.
B, Average lesion number and lesion volume (on day
10, the acute exacerbation period; n = 5 in
control group, n = 3 in single therapy group,
n = 5 in combination therapy group).
C, Early CNRs at 6 minutes after MPO-Gd injection
(n = 3 in control group, n
= 3 in single therapy group, n = 5 in
combination therapy group) and MPO-specific lesion activation ratios
(n = 3 in control group, n
= 3 in single therapy group, n = 5 in
combination therapy group). Swiss Jim Lambert mice (8–10 weeks
old, female; National Cancer Institute, Frederick, Md). ABAH =
4-aminobenzoic acid hydrazide, GA = glatiramer acetate. *
= P < .05, ** =
P < .01.
