[Morphological and cytological characteristics of the burn healing process by various treatment methods]

Morphological and cytological methods were used to study the healing of a burn wound in local isolation wards (an open treatment method) and under ointment bandages (a closed treatment method). Biopsy specimens and imprints from the burn wound surface were taken from 40 patients. During treatment in an abacterial medium, burn wound was rapidly decontaminated, which was a consequence of the appearance in wound exudate of segmented neutrophils with marked neutrophilic granularity. Granulation tissue was formed in the wound cavity at the 5th-7th day after the treatment commencement. During treatment under bandages wound decontamination was extremely slow. For a long time wound exudate shows the predominance of dystrophically changed neutrophils, while granulation tissue in the wound cavity if formed only at the 21st-24th day after the treatment commencement.
