title: [Features of the healing of suppurative wounds in patients undergoing treatment with collagen preparations (histochemical and electron-microscopic study)].
abstract: The dynamics of purulent wound healing developing in patients surgically treated for phlegmons or abscesses was studied histochemically and electron microscopically on the material of successive biopsies. It was shown that purulent wound healing is characterized by the desynchronization of inflammation and regeneration associated with the reduced macrophagal response and disturbances of the microcirculation system. Collagen sponge reduces inflammatory changes, activates the macrophage reaction, restores intercellular interactions, normalizes the microcirculation system, enhances proliferation and differentiation of fibroblasts, collagen synthesis and secretion, processes of fibrillogenesis, maturation of granulation tissue, epithelialization.
