在医学领域中,激光的应用日益广泛,应用不同性能的激光照射治疗某些疾病已取得了一些经验。但是激光照射后引起机体的一系列生物学效应,还有待于进行系统的研究.重庆医学院采用重庆光机所先后研制的卷筒式,倒空式两种不同能量(0.2mJ、3mJ)的氮子子激光器照射家兔、大鼠、豚鼠进行激光生物学实验观察,发现对试动物有镇痛作用;0.2mJ 氮分子激光对淋巴细 In the medical field, the application of lasers has become more and more extensive, and some experience has been gained in the application of laser irradiation with different properties to treat certain diseases. However, a series of biological effects caused by laser irradiation have yet to be systematically studied. Chongqing Medical College used the reel type developed by Chongqing Opto-Mechanical Institute and emptied two different types of energy (0.2mJ, 3mJ). Laser experiments were performed on rabbits, rats and guinea pigs exposed to a nitrogen laser, and analgesic effect was observed on the test animals; 0.2mJ nitrogen molecular laser was applied to lymphatics
