Objective. To study the functional activity and cytoarchitectonics of neutrophilic granulocytes by the atomic force microscopy technique in the patients with mechanical jaundice of benign genesis of varying severity.
Methods. The subject of the study were 92 patients aged from 47 to 69 years undergoing the in-patient treatment in the surgical departments of medical institutions in Krasnoyarsk with the diagnosis of mechanical jaundice of benign genesis. The control group consisted of 60 donors, comparable in sex and age with the main group. Depending on the severity of mechanical jaundice, luminol-dependent chemiluminescence of neutrophils was investigated and atomic-force microscopy of neurophilic granulocytes was performed to determine the shape, membrane state, geometric dimensions and adhesion forces of the blood neutrophils.
Results. In patients with mechanical jaundice, the intensity of spontaneous chemiluminescence depends on the severity of mechanical jaundice. The kinetics of the chemiluminescent response of the peripheral blood neutrophils indicates an increase in the compensatory functional capacity of this cell population in case of mild degree of mechanical jaundice severity with their depletion in parallel with the increase in the severity of mechanical jaundice.
Atomic force microscopy revealed violations of the structural organization of the neutrophil granulocyte. With increasing severity of mechanical jaundice, neutrophil became convex in shape, the number of segments of the nucleus increased, the cell membrane became irregular, the neutrophil volume reached 62.20 + 5.94 μm3. The magnitude of the adhesion forces of neutrophils decreased by 25% in patients with class B severity of mechanical jaundice and by 31% with class C severity of mechanical jaundice.
Conclusions. Based on the analysis of the chemiluminescent activity of neutrophilic granulocytes and their cytoarchitectonics, we concluded that the functional capabilities of neutrophilic granulocytes in mechanical jaundice are depleted in parallel with the increase in the severity of mechanical jaundice. Dysfunctions of neutrophils in mechanical jaundice are caused by the change in its cytoarchitectonics and by the decrease in adhesion forces.
