Immune histochemical study of KI-67 level and ribonucleic acid in the process of healing of burn wounds after treatment with drugs containing dexpanthenol and ceramide

Abstract

Ceramides are structural components of the stratum corneum that regulate cell proliferation and differentiation. The study of the effect of the cream containing dexpanthenol and ceramide on the proliferation processes and regeneration of burn wounds in rats. Experimental rats with III-A degree thermal burn were treated separately with the following preparations: Cream with ceramides, cream with dexpanthenol and ceramides and cream "Bepanten". The proliferative-regenerative activity of the drugs was investigated by studying the content of the Ki-67 producing cells and the content of ribonucleic acid (RNA) in the cytoplasm of the granulation tissue fibroblasts. Ceramides contributed to wounds healing, increasing the content of Ki-67 antigenpositive cells, accelerating the formation of scar in the wound. The therapeutic effect of creams with ceramides exceeds the efficacy of the reference preparation “Bepanten” cream. The addition of ceramides to dexpanthenol increases the quality and reduces the wound healing time. © 2019, AMG Transcend Association. All rights reserved.
