Table 2. Effect of TX14(A) on Formalin-evoked Flinching

Sum flinches counted per phase after injection into the hindpaw of either 5% or 0.5% formalin in rats treated with TX14(A), either by intraperitoneal (IP) or intrathecal (IT) administration 30 min before formalin injection. Data are mean ± SD. No significant differences between groups were noted using one-way analysis of variance or unpaired t  test as appropriate.
