The effect of α-terpineol on spinal levels of inflammatory cytokines in rats subjected to neuropathic pain. The concentration of IL-1β and TNF-α were measured in the lumbar part of the spinal cord using the ELISA method on the 14th day after the ligation of the sciatic nerve. Samples were from four animals and were duplicated. Each column represents mean±SEM for four rats. *P<0.05, **P<0.01, ***P<0.001 (compared to control); ##P<0.05, ###P<0.001; GBP: gabapentin; Control: normal saline + tween 80
