Abstract
The nervous system has an important and vital role in the human body, but unfortunately the repairment of damaged nervous tissue is very slowly. For a long time, the scientists have been involved in finding ways to speed up this process. Radiation of low power He-Ne laser has been suggested to as a way to improve this issue. In this study, 20 rats were divided randomly into control and case groups. The sciatic nerves of all these rats were damaged under general anesthesia and sterile conditions. The day of surgery was considered as the day zero. Rats of case group received every day laser radiation (?=65 mm). At 27th day rats were killed by ether and the sciatic nerve was studied histologically. Data was analysed and the difference was significant. In the case group the repairment was faster. We concluded that low power He-Ne laser radiation on crushed sciatic nerve of the rats has accelerated the nerve repairment process.
