自1975年以来

低功率氦氖激光照射穴位(简称激光针)的临床报道与日俱增

但其临床与动物实验的生物学效应在国内未见系统报道。本文侧重报道应用激光针治疗近视眼等五种疾病和家兔尺桡骨双折等两组动物实验

hydrogen-helium laser of low power has been used in medical treatment. But reports about its biological effect are rare. This paper recorded rheoencephalograms

volume pulse ways of finger and/or toe

skin temperatures

pain tolerance thresholds and two-point discrimina- tions of myopia and hypertension before and after the laser treatment. And it recorded the changes in X-ray examination

radioactive isotope ex- amination and pathological examination of ulna's and radiu's fracture of rabbits before and after laser treatment to observe the biological effect of laser acupuncture. The results were as follows: 1. Laser acupuncture could improve the organ circulation. 2. Laser acupuncture could raise the skin temperature of the body as a whole. 3. Laser acupuncture could heighten the thresholds of pain and two points discrimination. 4. Laser acupuncture might help to strengthen resistance of the bady

to relieve pain

to diminish inflammation and to improve fracture inten tion. The above results indicated that hydrogen-helium laser of low power did have acupuncture-like action. On the other hand

the impairment of spinal cord in patient and animal could impede this action. Therefore

we preliminarily suppose that acupuncture-like action of laser is accomp- lished through autonomic nerve-medium-blood vessel reaction system. As we all know

laser is a radiation of light. Besides the acupuncture-like action

laser has the action of electromagnetic induction and light-chemical reaction

which remain to be further investigated.
