Fig. 2From: Anti-allodynic effect of intrathecal processed Aconitum jaluense is associated with the inhibition of microglial activation and P2X7 receptor expression in spinal cordChronic effects of intrathecal (i.t.) PA on allodynic response to von Frey filaments following spinal nerve ligation (SNL). Each group received i.t. PA (N = 8) or saline (N = 8) once daily for 5 days. ‘Pre’ and ‘Post’ on the x-axis represent the PWT measured 10 min before and 30 min following i.t. PA injection, respectively. *P < 0.05 vs. corresponding PWT of the saline group measured prior to injectionBack to article page
