Experimental evaluation of the effectiveness of wound dressings based on biologically active substances from marine hydrobionts

Resumo

This article presents the experimental data on the testing of new wound dressings, viz., porous plates, prepared on the basis of chitosan and calcium alginate that contain biologically active substances (BASs) derived from marine hydrobionts. In a burn wound model in guinea pigs, we revealed a positive effect of tested samples of wound dressings on the wound-healing process; the data of planimetric and pathomorphological studies showing the acceleration of the process of regeneration in the wound are discussed. It was noted that the dynamics and patomorphological characteristics of the wound healing process differed depending on the structure of the BAS included into the composition of wound dressings (peptides, sulfated polysaccharides, a complex of amino acids and peptides).
