Abstract

The results of experimental studies of biocompatibility of the apatite cement, implanted in the muscular tissue of rats and bone tissue of rabbits were presented in this study. Investigations of the local reactions of the muscular tissue were carried out on 18 rats of Wistar type by implanting samples from the apatite cement in the dorsal muscles. Macroscopic and microscopic investigations were carried out 7, 14, 30, 180, 270 days after the implantation. Investigations of local reactions of bone tissue were carried out on 12 rabbits of New Zealand breed. By implanting the tested material into the femoral bone in the region of trochanter. Sections of the animals were made 1, 3, 6, and 9 months after the surgery. In the early period active inflammatory process was seen in the muscles in the direct vicinity of the implant and then it disappeared leading to formation of a thin fibrous connective tissue capsule. Histological investigations made of bone tissue later showed, formation of young tissue with small focuses of fibrous connective tissue. In the carried out investigations it was shown that the apatite cement is characterized with a high degree of biocompatibility and osteoinductive activity.
