[Changes in the blood rheological properties in the transcutaneous irradiation of the ulnar vascular fascicle with a helium-neon laser].

An investigation of blood rheologic properties in 12 patients with acute pneumonia has been made by using low-energy He-Ne laser (LG-79-2) irradiation of vascular fascicle. 37 exposures have been performed, 40 min each. Immediate effects of He-Ne laser were studied comparing blood samples taken before and after the radiation.
