Effects of irradiation of magnetized semiconductor laser on neural functional recovery

The effect on neural functional recovery irradiated by magnetized low intensity semiconductor laser is studied.The rabbits were divided into 3week,6week,9week,12week groups according to the observation period.The magnetized laser irradiated group,the laser irradiated group and the control group were used in each observation period.Irradiated the rabbits with injury of common personeal nerve in the laser irradiated group and the magnetized laser group,for 5min once a day,in 7 days.The regeneration of the axon,the latent rate of the common personeal nerve,the toe expansion test were all observed systematically in the groups.A few thin-regenerated axon were seen at 3rd week in the irradiated groups.The magnetized laser irradiated group was better than the laser irradiated group.The latent rate of the common personeal nerve was the magnetized laser irradiated groups than in control and the laser group.The amplitude of the irradiated groups was higher than in control.12 weeks postoperatively,the toe extension test was normal in the magnetized laser irradiated group,while among the laser irradiated group it was the same as seen at 9th week after operation in the magnetized laser irradiated group,and it was the same as seen at 6th week after operation among the control group.Magnetized low intensity semiconductor laser could promote the function of the spine motor nerve cells and accelerate the axonal regeneration.
