The effect of NAT administration on NK1 receptor immunoreactivity within the perivascular region following SCI.

<p>NK1 receptor immunoreactivity ranking at 10(A) and caudal (B). Sham sections demonstrated faint immunoreactivity surrounding the vasculature (C). Notably, at 24 hours post-SCI a marked increase was observed in both vehicle (D) and NAT (E) treatment groups. By 2 weeks post-SCI at 10 mm caudal vehicle treated (F) returned to sham levels, whilst NAT treated remained elevated (G). Median sham ranking indicated by the dashed line (A&B).
