TABLE 4

Comparison of the potencies (ED50) of the subplantar administration of l-NIL, NANT, ODQ, or Rp-8-pCPT-cGMPs (Rp-8) to suppress the mechanical allodynia (von Frey test), thermal hyperalgesia (plantar test), and thermal allodynia (cold-plate test) induced by nerve injury in WT mice at 21 days after CCI induction

Data are expressed as ED50 values (nanomoles) with 95% confidence limits determined on the quantal data of five to six animals per dose.
