The Influence of Propolis Nonwoven Scaffolds on Burn Wound’s Heparan Sulfates and Hyaluronan

Abstract

Innovative types of dressings should manifest biodegradability and non-immunogenicity and prevent dehydration. The mentioned technological features are demonstrated by polymeric, nonwoven propolis dressings, which exhibit regenerative properties, produced with the implementation of the electrospinning method. These features are highly needed in the course of burn wound healing. To analyze the dynamics of the changes in content of glycosaminoglycans (GAGs), such as heparan sulfates and hyaluronan, a well-known protocol of burn wound healing (the Hoekstra model) was used. Burn wounds were subsequently treated with nonwoven dressings containing either 5% wt or 10% wt propolis. Control groups were treated with either a saline salt solution or nonwoven dressings without propolis. Statistical differences between groups were determined by a multivariate analysis of variance (ANOVA) and Tukey’s post hoc tests. Evaluation of the effectiveness of nonwoven dressings containing 5% wt and 10% wt propolis in healing burn wounds, based on the dynamics and concentration of GAGs, revealed apitherapeutic positive effects on injured tissue healing. This research underscores the advantageous impact of utilizing nonwoven dressings containing propolis for the treatment of burn wounds.
