Information × Registration Number 0208U006047, 0107U006591 , R & D reports Title The investigation of anisotropy effects and processes of mass-transfer in bone fabric in connection with bone demineralization in the conditions of weightlessness popup.stage_title Head Brik O.B., Registration Date 26-03-2008 Organization nstitute of Geochemistry, Mineralogy and Ore Formation popup.description2 Research of interaction mechanisms of hydroxyapatite nanocrystals, that form mineral component of bone fabric, with the organic matrix of bones, and also factors, that affect on bone demineralization in the conditions of weightlessness imitation has been developed. Influence of conditions of weightlessness imitation on characteristics of rat bones by an electron paramagnetic resonance (EPR), proton magnetic resonance (PMR) and X-ray-structural analysis (RSA) has been investigated. By EPR method native radicals Rn, that are localized in the organic matrix of bones, radicals CO2 , which are localized on a surface of bioapatite nanocrystals, and admixture phases of carbonate matters have been explored. By methods PMR and RSA phase composition of explored bones has been investigated. It is established, that by means CO2 radicals can be studied changes of bone anisotropy, and also power of communication of hydroxyapatite nanocrystals with the organic matrix of bone fabric.
