RESUMO
The possibility of formation of connective-tissue vascular prostheses on subcutaneously implanted polychlorovynil base was demonstrated in experiments on rats. Suppression of the function of phagocytic cell with carrageenan decelerates, while its stimulation with tamerit accelerates the formation of connective-tissue autoprostheses.

Experimental studies on rats have demonstrated possibility of connective-tissue grafts formation on polyvinylchloride base introduced subcutaneously. Dynamics of autograft formation is characterized by gradual thinning of wall, regulation of collagen fibers, decreased number of cells with fibrocytes predominance. Autografts in carotid position retain its patency during 3 months, and endotheliocytes appear on their internal surface.
