As a result of the first session of intravenous laser 
irradiation of blood, it has been established that changes in the 
blood cellular elements, according to the data of cytometry, and in 
the blood and plasma viscosity are analogous to the changes occurring 
when a blood specimen is being incubated at a temperature of 4<$E{ 
italic 8 sup o}>C for 1 h or during its storage for 18 days at 1<$E{ 
italic 2 sup o}>C in a refrigerator: average dimensions of leukocytes 
decrease, thrombocytes decline in number, the deformability of erythrocytes 
is impaired, and the viscosity of the blood increases. Analogous changes 
in the cytometric and rheological indices, as well as a small hemolysis 
of erythrocytes, were observed on irradiation of a blood specimen 
in vitro. The suggestion has been made that the therapeutic effect 
of intravenous laser irradiation of blood is due to the generation 
of young cellular elements and their ejection into the blood channel 
instead of those damaged by the laser radiation.
