THE COMPARISON OF BONE FORMATION, MINERALIZATION AND CRYSTAL STRUCTURE BETWEEN THE INDUCED BONE AND SELF FEMORA IN RATS / 西安交通大学学报(医学版)

ABSTRACT

By using undecalcified bone sections, accompanied by tetracycline double labeling and analysis of infrared spectrogram, the bone formation, mineralization and crystal feature of induced ectopic bone and self femora in rats were compared. The results showed that from the 21th day to the 26th day as well as from the 26th day to the 30th day of the experiment, the rate of induced bone formation, mineralization was more active than that of the self femora on the 30th day, in the induced bone, the count of bone cell was much more, the volume of bone cell was much larger too; but the crystal structure of induced bone was indentical with that of self femora. The molecular formula was Ca_5[(OH)/(PO_4CO_3OH)_3].
