DRG following CCI were observed by using a polyclonal antibody to label the P2X

receptor. ATP-activated currents in corresponding DRG neurons fo
llowing CCI were observed by using electrophysiological technique. Results A significant increase in P2X

DRG and spinal cord on 7
14 d after CCI. In small diameter neurons
a significant increase in the number of cells exhibiting a transient current to ATP was observed on 7
14 d after CCI. Moreover
amplitude of these currents was increased. Conclusion After CCI
