[Light microscopic investigation of the tissue integration of Lyodura soft implants].
Commercial preparations of human "Lyodura soft" were implanted into the subcutaneous connective tissue of 40 Wistar rats. After survival times from 7 days up to 1 year the samples were examined by light microscopy. An initial reaction of mononuclear cells, activated fibroblasts, and some giant cells of foreign body type in the surrounding connective tissue is followed by the development of a fibrous capsule rarefied by cells around the implant in the time up to 3 months. After 6 months and more clearly after one year the capsule is reduced or even completely vanished. The implant remains then integrated in the subcutaneous connective tissue almost without residual reactions or signs of resorption.
