Abstract
Grade IIIB skin burns were treated with a composition based on oxidized dextran with a molecular weight of 40 kDa (oxidation of 7% glucose residues). On day 32 after burn infliction and from the start of the treatment, the area of skin defect in rats was 30% less than in the group without treatment and by 2.3 times less than in rats treated with panthenol. In rats treated with dextran-based composition or panthenol, the eschar was absent on day 21 after the start of the treatment; by day 32, we found cells of surface epithelium, hair follicles, and sebaceous glands above the scar tissue that were absent in untreated animals; in rats treated with the composition, their number was higher by 2.5 times than in animals treated with panthenol. Treatment with the composition increased volume density (by 2.5 times) and numerical density (by more than 3 times) of blood vessels in the wound and reduced signs of inflammation and fibroplastic activity of fibroblasts in comparison with the corresponding parameters in untreated animals or animals treated with panthenol.
