RHEOLOGY DYNAMICS OF THE BLOOD AND PLASMA OF RATS AFTER TRANSDERMAL LASER IRRADIATION OF THE TAIL VEIN IN THE INFRARED RANGE

Single transdermal laser irradiation of the tail vein of males of white mongrel rats with an average mass of 350-400 g in three different regimes has been carried out. The irradiation doses were chosen to be intermediate between therapeutic and surgical ones, and the radiation wavelengths were 806 nm and 2 m. The dynamics of the packed cell volume, deformability and cytometric indices of erythrocytes, and of the plasma and blood viscosity have been investigated. The rheological and cytometric changes in the blood caused by the irradiation stayed for several days. The observed rheologial changes are due to the removal of irradiation-damaged erythrocytes and the arrival in the blood channel of young and highly deformable red cells.
