This studies were to investigate the effects of low power Helium-Neon Infra-Red (He-Ne IR) laser on the healing of the peripheral neuropathy in diabetic rats. The twenty one Spraque-Dewley adult male rats were assigned to the 3 groups: the control group (7), the diabetic group (7) and the laser group (7). The diabetic group was induced with a single intravenous injection of 50mg/kg body weight streptozotocin dissolved to 0.01mol/L citrate buffer, pH 4.5. The experimental laser group was irradiated low power He-Ne IR laser for 5 minutes every day during 21 days to the diabetic group. The results were as follows: For on and two weeks with laser treatment, there were significantly increased the terminal latencies of the laser treatment group than those of diabetic group, but that was significantly decreased to be similar to the control group on the laser treatment group for three weeks. The change of the amplitude on the laser treatment groups for three weeks was significantly increased to be similar to normal group than that of the diabetic group. As the result, we thank that there were activately effected of lower power He-Ne IR laser on the heeling of the peripheral neurophathy in diabetic rats.
