Peculiarities of granulation tissue morphology around a netalotransplant in preoperative irrigation of the abdominal cavity

Abstract

The experiment investigated the influence of preoperative remote gamma therapy on the features of the morphology of granulation tissue around the elements of the reticular allograft of the muscular-aponeurotic layer of the anterior abdominal wall. It is established that the use of preoperative remote gamma therapy distorts the maturation of granulation tissue. There is a probable increase in the percentage of fibroblasts and a decrease in lymphoid cells, polymorphonuclear leukocytes, macrophages, and plasma cells in the granulation tissue, mainly on the 5th and 7th day after surgery. Also on the 7th day of the study there was an increase in the specific volume of collagen fibers, their optical density, as well as the specific volume of blood vessels. Keywords: preoperative gamma therapy, granulation tissue, reticular allograft.
