We evaluated the effects of the Gly-His-Lys-D-Ala peptide in a dose 0.5 μg/kg on skin wound regeneration in male Wistar rats (n=80) after initial surgical debridement when administered intracutaneously around the site of injury. Histological (severity of the inflammatory reaction, formation of granulation tissue, and epithelialization terms) and morphometric (number of fibroblastic cells, macrophages, granulocytes, and lymphocytes) studies were performed on autopsy specimens on days 3, 7, 10, and 30 of the experiment. Daily intracutaneous injection of the peptide resulted in an increase in the number of fibroblastic cells and macrophages, as well as in a decrease in the number of granulocytes against the background of active wound contraction on day 30 of the experiment. Thus, Gly-His-Lys-D-Ala alleviated the inflammatory reaction and promoted the regenerative processes.
