The aim of the investigation was to study the corrective action of low-intensity laser radiation on the in vitro morphofunctional state of stressed erythrocytes using interference microscopy. Materials and Methods. Blood samples of intact and stressed rats exposed to low-intensity laser radiation (LILR) were studied in experiments in vitro. The wavelength of LILR radiation was 890 nm. Erythrocyte morphology was studied using laser interference microscopy, malondialdehyde and adenosine triphosphate concentrations were assessed spectrophotometrically. Results. The action of LILR was found to cause no significant changes in the discoid form of erythrocytes and cellular metabolic processes, though it resulted in the appearance of projections on the surface. Exposure to stress promoted a decrease in discocyte count and a significant increase in echinocytes, stomatocytes and degenerative forms of cells with altered microrelief, which was combined with an increase in oxidation processes. The effect of LILR on blood samples of stressed animals led to a decrease in pathological forms of erythrocytes and restoration of cell surface architectonics.
The possibility of quantitative phase imaging method for the assessment of structural morphological erythrocytes peculiarities under normal and stress conditions were studied. It is stated that quantitative phase imaging is an important instrument which allows to visualize red blood cells. New aspects of stress influence on functional cells morphology are defined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
