Background: The relevance of the work lies in the search for new hemocontact drugs with hemocompatibility and a pronounced activation effect on the cellular and humoral blood systems for their possible use in clinical practice during low-volume hemoperfusion.The aim of this work was to assess the activation capabilities of three granular hemosorbents by the rate of adhesion of blood cellular elements to the surface of granules in vitro.Materials and methods. When using the method of low-volume hemoperfusion (LVH) in the clinic it is important to take into account the activation properties of solid-phase granular drugs. Blood-contact interaction was carried out in bench conditions with the use of donated blood in rotary mode. Blood samples were taken before the experiment and after 5, 20, 40 and 60 minutes. Changes in blood cell and subcellular populations were evaluated using the Sysmex XT 1800i hematological analyzer (26 parameters), which made it possible to indirectly judge the activation of blood cells. 30 experiments were conducted. To analyze the activation functions of the hemocontact preparations the speed-time adhesive profile of blood cells on the sorbent was used.Results. The effect of using the preparations Silochrome S-120 and SPS in comparison with SСT-6A HP as contact hemoactivators can be more pronounced, since the activation potential of these sorbents for blood cells is much higher. Silochrome S-120 has the highest activation capabilities compared to SPS and SKT-6A HP.Conclusion. Adhesion rate indicators can be indicators of the activation of blood cells upon contact with foreign surfaces and serve as a criterion for assessing the activation capabilities of these surfaces when using the LVH method in the clinic.
