(a) Photomicrographs demonstrating antirat CD68 immunoreactivity in macrophages (arrows) from cross sections of distal nerve cables of controls and FA-treated animals. Scale bars m. (b) Note the dramatically decreased density of macrophages with the concentration of FA. * indicates significant difference from other groups.
