医用激光广泛用于口腔粘膜疾患、良性肿瘤,以及癌前病变和恶性肿瘤的治疗。据报道,白斑症和乳头瘤激光照射后,有的病例转变为浸润癌,提示激光照射有促进致癌的可能性。文章对实验性致癌过程CO_2激光照射的影响进行了研究。 实验取体重约80～90g的6周龄雄性金鼠108只,常规饲养1周后,分成3组。A组:每周3次,连续5周仅行DMBA丙酮液(致癌剂)颊囊粘膜涂布,同时分
Medical lasers are widely used in the treatment of oral mucosal disorders, benign tumors, and precancerous lesions and malignancies. It has been reported that leukoplakia and papilloma laser irradiation, and some cases into invasive carcinoma, suggesting that laser irradiation may promote the possibility of carcinogenesis. The article studied the experimental carcinogenic CO_2 laser irradiation process. Experimental Take body weight of about 80 ~ 90g of 6-week-old male golden rat 108, routine feeding for 1 week, divided into 3 groups. Group A: 3 times a week for 5 consecutive weeks only DMBA acetone solution (carcinogen) cheek pouch mucosal coating, at the same time points
