Karazin Kharkiv National University popup.description2  Mechanical characteristics of newly formed calcium phosphate bioactive cements based on low temperature metastable nanocrystalline -TCP and β-TCP powders after vacuum heat treatment have been studied. The peculiarities of calcium-phosphate cements formation with the application of different kinds of powders and setting liquids of different chemical composition have been established. The optimal chemical composition of the setting liquid and the solid /liquid ratio were obtained. The setting process, the calorimetric characteristics of the interaction of TCP powders with the setting liquids, and the change in the mechanical characteristics of the formed cements during hardening were investigated. The studies of the behavior of cements in the biological environment on rats were conducted. After removing the rats from the experiment by the overdosing of the ether, the bone condition and surrounding bone defect were studied using morphological analysis methods. For this purpose the distal fragments of the femur defect of animals were isolated and fixed in the solution of 10% neutral formalin, decalcified in the solution of 5% nitric acid, dehydrated in alcohols of increasing strengthand poured into celloidin. The prepared histologic sections had thickness 7–9 μm, covered by hematoxylin and eosin, as well as Van Gason picrofuxin. Product Description popup.authors Goncharenko Anton V. Zyman Zoltan Z.
