The number of Iba1 positive cells in the lumbar part of the spinal cord in rats that were subjected to neuropathic pain. Each column represents the percentage of ionized calcium-binding adapter molecule 1 (Iba1)-positive cells in the sham, control, α-terpineol-, and gabapentin-treated groups. Data from five slices of each sample were averaged and expressed as mean±SEM for each group (n=4). *P<0.05, ***P<0.001 (compared to control); #P<0.05, ###P<0.001; GBP: gabapentin; Control: normal saline + tween 80
