Purpose: The purpose of this study was to investigate the effect of electroacupuncture on NeuN expression in ventral horn motor neurons of spinal cord, changes in pain thresholdchanges in motor function in rats with partially dissected sciatic nerves. Method: A total of 120 male Sprague-Dawley rats were randomly divided into two groups, a control group and a group administered electroacupuncture at ST36, LI11 and SP9 with 120 Hz and 0.5 mA. Animals were sacrificed on days 1, 3, 7, 14 and 28 after nerve injury (the sciatic nerve was partially dissected). The pain threshold was recorded by an Analgesia? meter and a BBB? score was calculated for motor function. After preparing lumbar spinal cord slide sections, they were immunostained with NeuN antisera (1:2,500). Results: The numbers of NeuN immunoreactive neuronsin the electroacupuncture group was increased compared to the control group. The numbers of NeuN immunoreactive neurons on days 14 and 28 day were different (p<0.05), as were the numbers on days 3 and 7 (p<0.01). The pain threshold BBB score for the electroacupuncture group was higher than for controls. Conclusion: The increase in pain threshold, BBB-score and number of NeuN immunoreactive neurons inventral horn motor neurons of spinal cord in rats withnerve dissection showed that electroacupuncture can attenuate pain transduction and increase motor function. Also, NeuN was a good marker for identifying the degree of nerve cell loss after nervous system injury.
