Ecology and bone structure state

The structural state of radioulnary bones of European mooses living in different ecological conditions has been studied by x-ray diffraction methods. The x-ray diffraction patterns were fixed at the wide angular interval including a small-angle part. Parameters of microporosity were calculated from angular distributions of small-angle scattering intensities. A width and an intensity of collagen reflections at the middle angles allowed us to define the texture perfection of structural components. Finally the spectrum of observed reflections and their angular positions permitted us to find the phase composition. It has been established that unfavorable ecological conditions cause the loosening of bone tissues and the disorientation of the structure elements. Bedsides the phase composition and the relative content of amorphous and crystalline components change. The experiments have shown that observed diffractive effects allow us to elaborate methods controlling structure state of bones.
