Macrophage and Astrocyte Quantification in the Injured Spinal Cord. A) Statistical analysis of macrophage numbers in the spinal cord of both treatment groups indicated a greater macrophage presence in control animals than in liposome-treated. Specifically, in control animals these numbers were significantly higher 1-2 mm both rostral and caudal from the SCI epicentre, as compared to liposome-treated animals (*P < 0.05, **P < 0.01, respectively), while no differences were found at the SCI epicentre. B) Astrocyte quantification 3 mm rostral from the lesion epicentre revealed a greater reduction in astrocyte activation in control animals (*P < 0.05). No differences were observed between groups caudally. Columns represent an averaged mean (n = 10) and error bars indicate error of mean (+/- S.E.).
