[Effect of infrared impulse laser irradiation on the development of albino rat embryos]

Development of the white rat embryos has been studied under effect of infrared laser beams (wave length--0.89 mcm, impulse frequency--300 Hz) during various periods of pregnancy. Exposure of the female rats for 256 and 128 sec produces an increased preimplantational death of embryos and certain disturbances in formation of the osseous skeleton in some embryos.
