作者在实验室和临床上研究氦氖激光对组织损伤和口腔粘膜病的治疗作用。用192只大白鼠作试验,在动物舌前三分之一粘膜造成电灼伤,然后进行氦氖激光照射,根据照射强度(功率1、100、200、400mw/cm~2)和照射次数(1、5、10次)分组,每次1分钟。24只动物不照射舌伤口作为对照组。照射后1～30天内的不同日期取材制标本进行组织学检查。用细胞化学染色法检查细胞 The authors studied the therapeutic effects of He-Ne laser on tissue damage and oral mucosal disease both in laboratory and clinical settings. A total of 192 rats were used to test the electrical burns in the mucosa of the anterior third of the animal and then irradiated with He-Ne laser. According to the irradiation intensity (1,100,200,400mw / cm ~ 2) and the number of irradiation , 5,10 times) for 1 minute each. Twenty-four animals did not irradiate the tongue wound as a control group. Radiation from 1 to 30 days after different samples taken specimens for histological examination. Cells are examined by cytochemical staining
