Histological assessment of IBA1-positive cells in the lumbar spinal cord region, PAG, and RVM: (a) representative IBA1-stained image of the spinal cord (40x magnification; scale bars represent 50 μm); (b) representative IBA1-stained image of the PAG (40x magnification; scale bars represent 50 μm); (c) area under the curve analysis of the average number of IBA1-positive cells on serial sections in the lumbar region of the spinal cord. Average number of IBA1-positive cells in the PAG and RVM of the brain (d and e, respectively). Error bars represent SEM ( animals per control, CAIA+PAR 1 mg/kg, and CAIA+PAR 4 mg/kg, animals per CAIA), , , .
