Behavioral changes after separately intrathecal injection FC and 0.9% NS of SNL model, red arrow is sign of intrathecal injection. A: changes of mechanical threshold of bilateral side paws: After injection FC, ipsilateral paw of SNL model showed their mechanical threshold were up, # P < 0.05 vs ipsilateral side paw of SNL + NS group. After injection FC,contralateral side paw of SNL model showed their mechanical threshold were up, *P < 0.05 vs contralateral side paw of SNL + NS group. B: changes of thermal threshold of bilateral side paws, after injection FC, ipsilateral paw of SNL model showed their thermal threshold were up # P < 0.05 vs ipsilateral paw of SNL + NS group. After injection FC,contralateral paw of SNL model showed their thermal threshold were up *P < 0.05 vs contralateral paw of SNL + NS group n = 6.
