| Abstract: | AIM To study the effect of growth associated protein 43 (GAP 43) expression in spinal cord after irradiation on injured rat sciatic nerve by diode laser with a power output of 15 mW. METHODS Injured sciatic nerves were made in 96 male adult SD rats. Injured nerve was irradiated by diode laser. The changes of GAP 43 in spinal cord wereimmunohistochemically studied. RESULTS There was not any different between the laser irradiation group and the control group within one week. More expression of GAP 43 at the second and the fourth week and less at the eighth week were observed in laser irradiation group. CONCLUSION The expression of GAP 43 in spinal cord can be changed by diode laser irradiation in injured sciatic nerve. Diode laser irradiation can promote nerve regeneration. |
