[Comparative histological and light-microscopic cytomorphometric studies of the tissue repair processes in postoperative wound complications treated locally with helium-neon laser radiation or a proteolytic enzyme].

Morphological studies were carried out on tissue material, removed from wound peripheral parts during application of secondary sutures on 69 complete perineal wound dehiscences of parturients prepared by helium-neon laser irradiation according to a method described by us, as of wound peripheral parts of 15 perineal wound dehiscences, prepared by alphahymotripsin dissolved in a solution with vitamin C. Histological preparations were stained by hematoxilin-eosin by van Gieson (for collagenous fibres), by Weigert (for elastic fibres) and by Gomori (for reticular fibres). Light microscopic cytomorphometric studies were made by a graduated ocular micrometer on stained with hematoxilin-eosin tissue sections with the help of standard optical system.
