Fig. 4From: Anti-allodynic effect of intrathecal processed Aconitum jaluense is associated with the inhibition of microglial activation and P2X7 receptor expression in spinal corda Increased expression of P2X7R mRNA in the ipsilateral dorsal spinal cord following L5 SNL. Gel panels show RT-PCR products from the spinal cord of naïve rats on days 3, 5 and 7 following SNL. P2X7R mRNA is significantly increased after SNL compared to naïve animals. b Intrathecal (i.t.) administration of PA blocked the increase in P2X7R mRNA expression in the ipsilateral dorsal spinal cord on day 7 following SNL. N = 7 per group. *P < 0.05 vs. naiveBack to article page
