[The effect of hemosorbents on the structure of polymorphonuclear leukocytes in man].

The effect of various hemosorbents (HS)--carbon and textile--on the structure of neutrophils has been studied in vitro. It has been shown that the mechanism of cell degranulation is universal on various HS and does not depend on the anticoagulant used or on blood donor diseases. The degree of degranulation both for primary and for secondary granules increases with the prolongation of blood contact with HS, directly depends on HS--blood ratio and is determined mainly by the type of HS: degranulation on textile HS is considerably greater than that on carbon HS. Degranulation was confirmed by elevated blood plasma concentration of lactoferrin, a specific marker of secondary neutrophil granules. It is suggested that cell degranulation on HS leading to a considerable posthemosorption increase in the blood plasma level of biologically active intracellular components is essential in the process responsible for correcting hemosorption effect in different diseases.
