低功率半导体激光照射对大鼠损伤神经功能恢复的实验研究

An experimental study on effects of neural functional recovery of rats irradiated by low intensity diode laser

目的：研究不同输出功率的半导体激光对大鼠神经功能恢复的影响。方法：采用半导体激光照射ＳＤ 大鼠损伤的坐骨神经，观察５ｍ Ｗ、１０ｍ Ｗ、１５ｍ Ｗ 不同剂量的半导体激光照射对神经功能恢复的影响及病理变化。结果：半导体激光照射促进损伤神经轴突及髓鞘的再生过程，１５ｍ Ｗ 的半导体激光照射对神经功能的恢复作用较明显。结论：１５ｍ Ｗ

Objective: The effect on neural functional recovery of rat irradiated by diode laser with different power output were studied. Method: In order to observe the neural functional recovery and pathological changes of rat, diode laser with power output of 5mW,10mW,and 15mW were used . Result: The irradiation on injured sciatic nerve by diode laser could promote the regeneration of axon and sheath. Irradiation with power output of 15mW of diode laser on injured nerve had a better functional recovery compared to control group. Conclusion:Diode laser with power output of 15mW can be used in treating injured nerve of rat. Author′s address\ Xijing Hospital, Fourth Military Medical University , Xi′an,710032
