We conducted an experiment in curing traumas on 6-week old balb/c mice by He-Ne laser scanning. Square traumas were prepared in 20 mice at bilateral sites 5mm from the dosal median line. The right traumas in 12 animals were radiated by a He-Ne laser with an energy density of 4 Jules/cm2/2days from a day after trauma preparation, The left traumas served as a radiation control group. A slit of light 9mm×1mm was scan-radiated at a velocity of 2 sec./cycle for a width of 10mm using newly-developed He-Ne laser scanning apparatus. The remaining 8 animales (16 wounds) served as a non-radiation control group.
The mean length of the shorter sides of the square traumas were 5.5mm in the non-radiated and radiated traumas in the radiated group was 5.8mm and 5.7mm respectively, showing no significant diference at the t-testing. The average time required for the traumas to heal was 10.5 days for The non-radiated group and 10.8 days for the non-radiated traumas in the radiated group. The period required for the radiated traumas to heal was significantly shorter, 6.3 days (p<0.01). We thus confirmed that He-Ne laser scanning radiation is effective for treating traumas.
