Abstract

Background. The development of biocompatible polymeric implant materials and providing them with biological activity is an urgent task that can significantly increase the effectiveness of such materials when used in medical practice. Objective. Investigation of the interaction of connective tissue culture matrix cells with a prolonged form of the proteolytic enzyme lysozyme as part of a polyurethane implant in vitro and study of the effect of this form on cells and tissues during implantation in experimental animals in vivo. Methods. In order to study the possible cytotoxicity of the components of polymer composite materials and the effect of lysozyme on the growth and development of the culture of fibroblastic elements, studies were performed by tissue culture in vitro. Polymeric composite materials based on polyurethaneurea without and with lysozyme were implanted into the body of white laboratory rats of the Wistar line. Cellular responses of the body after implantation were studied by light microscopy by analysis of histological micropreparations. Results. Biological studies have assessed the effect of prolonged lysozyme on cells and tissues in vitro and in vivo. Conclusion. The fibroblast tissue culture method showed the effectiveness of biologically active polyurethaneureas with prolonged release of lysozyme, which was expressed in the prolongation of the dynamics of growth and development of cellular elements in vitro. It has been shown that lysozyme in the composition of polymer composite materials had a biological effect and helped to reduce the cellular response to the implantation of polymer samples, accelerating the formation of connective tissue capsules around the implants.
