[Effect of helium-neon laser radiation on the morphology of experimental allergic contact dermatitis].

Clinical and morphological studies of guinea-pig skin in the areas of dermatitis induced by application of dinitrochlorobenzene (DNCB) have shown the decreased skin response to DNCB after treatment with helium-neon laser (wave length 632.8 nm, power density 8-10 mvt /cm2). The ultrastructural signs of cell metabolism activation in the epidermis and derma as well as activation of capillary transport have been discovered in allergic contact dermatitis areas after treatment with helium-neon laser.
