AB  - Hydroxyapatite (HAp) is an extensively studied material with known biocompatible and osteoconductive properties in bone tissue reconstruction. The improvement of the osteogenetic potential of HAp has been tested through modification of its structure, by replacing Ca2+ ions with Co2+ ions. In our study, we comparatively analyze the osteogenetic potential of the synthesized HAp and Co2+-substituted HAp (HAp/Co) designed on the nano-scale with the aim of specifically stimulating osteogenesis in vivo. We present a quantitative study of the microscopic organization and structure of the newly formed tissue in a bone defect after 12 weeks and 24 weeks. A quantitative analysis of the calcium, magnesium and phosphorus content in the defect and its close environment was used to determine the deposition of minerals after bone reconstruction. The defect reconstructed with HAp/Co nanoparticles (Co2+ content 12 wt%) was filled with a new tissue matrix composed of dense collagen fibers containing centers of mineralization after 24 weeks. The mineral deposition rate was also higher when the defect was reconstructed with HAp/Co than when it was filled with pure HAp. A histological analysis confirmed that the alveolar bone, in which osteoporosis-induced defects were repaired using HAp/Co nanoparticles, was recuperated. © 2015 Jilin University.

AB  - Recent studies have shown that the behavior of nanoparticles in in vivo conditions is not solely dependant on their physical properties, such are size and shape. The surface of nanoparticles in biological fluids interacts with biomolecules such are proteins, adsorbs these molecules, and leads to formation of nanoparticle-biomoelcular complex known as “protein corona”. This protein corona changes the properties of nanoparticles and their behavior in vivo. In this work three types of nanomaterial based on Hap and polymers were incubated in rats plasma, and the identification and quantification of proteins in protein corona that had formed around these nanoparticles, was done by means of electrophoresis and mass spectrophotometery.

AB  - Bone loss during the systemic osteoporosis has an important role in dentistry and medicine. The aim of the study was the application of bioactive micro and nanocomposite materials, alone, and in combination with autologous plasma in osteoporotic jaw bones of rats with artificially induced osteoporosis. The effect of these composites was measured by histomorphometric and atomic absorption spectrophotometric analysis. According to the best obtained results in regeneration and recovery of the resorbed alveolar bone, it can be concluded that nanocomposite combined with autologous plasma may be the material of choice to replace the osteoporotic damaged jaw bone.
