Biostability and morphology of tissue reaction of some synthetic polymers.

Synthetic polymers as tissue substitute are more and more widely used in medicine today. Therefore it is necessary to continue to complete our knowledge on the subject of the mutual interaction of the organism and tissue substitutes of synthetic polymers. The influence of the organism on the degradation processe of some synthetic textile fibres made of polyester was studied polypropylene and polyamide, which are either suggested or already used in the production of vascular protheses and other tissue substitutes. The morphological picture of tissue reaction to implanted synthetic fibres, the mechanical properties of the fibres and changes in their surface structure after 4-360 days after implantation were also studied.
