Abstract

The influence of low-intensity laser irradiation on backscattered radiation from the skin vascular plexus is investigated in vivo. Laser irradiation of the blood in the absorption range of haemoglobin leads to an increase in the intensity of the back-scattered emission. The calculated temperature gradients are sufficient to produce structural and conformational changes in the cellular proteins of the erythrocytes and/or to produce a change in the permeability of membrane and cause the disaggregating of the aggregates of erythrocytes. A theoretical calculation for the increase in the intensity of the back-scattered emission with the disaggregating of erythrocytes was performed.
