Anotācija Creation of artificial organs and substitutes for biological tissue is one of the most important problems of biomechanics. In the present study, a procedure is described for obtaining natural hydroxyapatite (NHAp) from bone tissue of cattle. The results of experiments, performed by absorption method of infrared spectroscopy, show that the protein was removed from the heat-treated specimens of bone tissue practically completely. The structure of bone tissue before and after deproteinization has been investigated by the method of optical microscopy. The characteristics of mechanical properties such as Young’s modulus (initial modulus of elasticity), ultimate tensile stress, ultimate tensile strain, ultimate compression stress have been determined. The density and porosity of cattle bone tissue before and after deproteinization have been determined by water uptake.
