title: Application of porous bioceramic in experimental therapy of bone injuries. III. Dynamics of the callus development at the site of porous bioceramic implantation. Morphological, histochemical and histoenzymological studies.
abstract: In this work the biocompatibility of porous bioceramic implanted to the rabbit femoral bone was studied. The animals were killed 3, 6, 9, 14, 18 and 30 days after implantation and the callus with surrounding periosteum from the site of implant was taken for the studies. Morphological investigations of the callus were carried out up to the 30th day of healing of the bone tissue. Moreover, acid mucopolysaccharides level and activity of enzymes (acid and alkaline phosphatase, aminopeptidase, non-specific alpha-esterase, adenosine triphosphatase and succinate dehydrogenase) were studied up to the 18 day of the callus development. The results show that after bioceramic implantation, morphology of particular stages of the callus development, behaviour of acid mucopolysaccharides as well as localization and activity of enzymes are the same as in the normal healing process of the injured bone tissue. After 30 days total union of the mature bone tissue with bioceramic was established. We conclude that porous bioceramic satisfies the requirements for biomedical materials and may be safely used in the treatment of certain bone system diseases in humans.
