“…A set of studies was performed for each devitalization stage: the morphological, structural, antigenic characteristics and biomechanical properties of xenopericardium under low temperatures, ionizing radiation and their joint impact were studied. Cryoradiation treatment caused degradation and surface lining loss (endothelium and mesothelium) and pronounced destructive changes of cell elements in the pericardium tissue, while preserving the spatial arrangement and structural integrity of fibrous components of the connective-tissue base and their spatial relationship (10, 11). Analysis of the results demonstrated that matrix proteins (elastic membranes and related collagen fiber bundles) were resistant to the impacts in use, did not undergo degradation and preserved their integrity.…”
