EFFECT OF THE LASER BEAM ON THE SKIN .3. EXPOSURE OF CYTOLOGICAL PREPARATIONS

[摘要] The effect of laser beams of light and moderate intensities was observed on various cytological preparations. Coloring, either natural from melanin-containing material, such as in melanomas, or induced by vital staining with such dyes as Evans Blue, Trypan Blue, and Eriochrome Black T increased the energy of absorption of the laser beams. Mounts of black hairs on slides are suggested as models for study of materials for the protection from the laser beam.
