[Results of helium-neon laser radiation action on the hematopoietic system experimentally and in the laser therapy of surgical diseases].

The investigation of effects of the red light of the helium-neon laser on hemopoiesis of experimental animals has provided data on the activation of erythropoiesis and the presence of the leucocyte redistribution reaction in the peripheral blood. No pathological changes in the morphological composition of the peripheral blood were detected in patients with a deforming arthrosis and patients with gastric ulcer in the process of laser therapy. Favourable changes were noted.
