<title>Influence of low intensive laser irradiation on intercellular intertissue interactions</title>
Abstract
The irradiation of large surfaces or the whole body with copper vapor or ultraviolet lasers causes the structural changes of the bone marrow, skin, and intestine cells indicating the acceleration of their proliferation and differentiation. The increase of migration of the bone marrow cells in stroma and epithelial layers of organs indicates the intensification of intercellular intertissue interactions. This phenomena takes place in doses not more than 0.2 J/cm<SUP>2</SUP> for ultraviolet and 0.5 J/cm<SUP>2</SUP> for copper vapor lasers. The greater of the doses cause the damages of bone marrow, skin, and intestinal cells.
