Paper Abstract

An investigation was made of changes in the densities of small, middle-sized, and large lymphocytes when the popliteal lymphatic nodes of white rates were exposed to (lambda) equals 0.63 micrometers He-Ne laser radiation with the energy densities of 0.3, 3, and 30 J cm-2. Initially, different anatomical structures of the left and right popliteal lymphatic nodes had virtually similar lymphocyte densities. After a single exposition of these lymphatic nodes to low-intensity He-Ne laser radiation, lymphocyte densities changed. These changes were dependent on the energy density of laser radiation. It was found that the energy density of 0.3 J cm-2 produced insignificant changes. As the energy density increased, the density of lymphocytes exhibited more pronounced changes. The energy densities of 0.3 and of 3 J cm-2 initiated activation processes in the lymphoid tissue of lymphatic nodes. The energy density of 30 J cm-2 produced notable destructive changes in the tissue of lymphatic nodes. Apart from that, it was found that the contralateral (non-exposed) lymphatic node revealed similar changes in the density of lymphocytes as compared with the exposed lymphatic node. This provided evidence for a systemic reaction of the immune system to He-Ne laser radiation.
