Application of porous bioceramic in experimental therapy of bone injuries. I. Morphological and histochemical studies in the control animals.

ABSTRACT

The process of healing of the rabbits' bone tissue after mechanical injury was studied. The femoral bone was injured by means of oscillating saw. The animals were killed 3, 6, 9, 14, 18 and 30 days after operation and the callus with the surrounding periosteum was taken for morphological examination. Besides, acid mucopolysaccharides level and aminopeptidase activity in the callus (up to the 18th day of healing) were determined. The time of total bone union was established for 30 days.
