Wound-healing activity of polyhexamethyleneguanidine hydrochloride hydrogel and extract of Bergenia crassifolia on thermal burn simulation

Abstract

The results of a study of the wound healing activity of a composition based on the hydrogel of polyhexamethylene guanidine hydrochloride and Bergenia crassifolia extract, under conditions of modeling thermal burns in laboratory animals (rats), are presented. It was found that the composition affects the change in the summary antioxidant and leukocyte activity towards the normalization of these indicators. Morphological analysis of the slices showed that, under the influence of a polyhexamethylene guanidine hydrogel composition and B.crassifolia extract, healing proceeds more intensively than in the control group and is manifested by a smaller thickness of the leukocyte-necrotic scab, accelerated epithelization, and complete closure of the skin defect.
