[Hematologic engineering in modern transfusiology]

Three groups of hematological engineering methods have been considered: (1) blood gravitation surgery, (2) sorption methods, (3) blood irradiation methods. They were comparatively characterized with respect to their effectiveness. Combined employment of various methods of hematological engineering permits one to avoid shortcomings and intensify the effectiveness of each group of methods. It is shown that new internal environment of the body is developed in the process of hematological engineering operations. It is stressed that hematological engineering combines methods of blood reconstruction.
