Abstract

In experiments on white rats the influence of He-Ne laser radiation ((lambda) -- 632.8 nm, power density -- 1.5 mW/cm²) and electromagnetic field of extremely high frequency (42.0 - 43.3 GHz, 1 mW/cm²) on transplantability and growth of fibroadenomas of mammary glands, and influence of low power laser irradiation on transplantability and growth of Walker carcinosarcoma were investigated. Skin at the site of future transplantation underwent irradiation. He-Ne laser and EHF-radiation were stated to change properties of tissue accepting tumor cells. A single laser irradiation of the inoculation site of Walker carcinosarcoma cells produced no effect on tumor transplantability, but increased the average life span of animals. Laser and EHF irradiation increase the transplantability of fibroadeonomas but depress growth and rate of multiplication of tumor cells.
