[The question of the transmissibility of the results of subcutaneous tests of biomaterials from animals to humans].

The histologic estimation of the subcutaneous connective-tissue reaction at implants forms an important part of the biocompatibility test. The connective-tissue capsulae around titanium implants in man, guinea-pig, and Wistar-rat were analysed by a special test system because of the question concerning the transmission of results of animal experiments on the man. The subsidence process of the thickness of the connective-tissue capsule and of the cell count per measuring fields were represented in dependence on the time. The findings showed the fundamental similar course of wound healing in man, guinea-pig, and Wistar-rat by the influence of an implant.
