[Bio-compatibility of different plastics (polyoxymethylene-copolymer, polyethylensterephthalate, polyethylene, polytetrafluorethylene) (author's transl)].

The bio-compatibility of different plastic materials were examined after their implantation in the back-muscle of 6-months-old male rabbits. Twelve weeks after the implantation chemical measurements (DNS-concentration of the tissue) and histological investigations of the surrounding tissue demonstrated for polyethylene the best bio-compatibility.
