Fig. 3From: The NO-cGMP-PKG signal transduction pathway is involved in the analgesic effect of early hyperbaric oxygen treatment of neuropathic painRT-PCR analysis of PKG1 mRNA content in the dorsal spinal horn. Statistical results: a Amplification curves; b Dissociation curves; c Relative PKG1 mRNA expression (PKG1/GAPDH). Data are shown as mean ± S.E.M, n = 6. *P < 0.05 vs. CCI; # P < 0.05 vs. HBO. HBO increased the expression of PKG1 in the dorsal horn of the CCI model. After intrathecal injection of L-NAME, ODQ and KT5823, PKG1 expression significantly decreased compared with groups treated with HBOBack to article page
