Originální abstrakt

The bone substitute consists of alpha-tricalcium phosphate and water solution of thermosensitive, copolymer based on poly(lactic acid), poly(glycolic acid) and poly(ethylene glycol) (PLGA—PEG—PLGA) [2]. The rheological properties during setting were studied in steady mode using controlled-stress rheometer. The microstructure after setting was investigated by scanning electron microscope, the compression test and accelerated degradation study at pH = 2.2 were performed on cement cylinders after 10 days of setting. The cytocompatibility was evaluated using human mesenchymal stem cells (hMSC) by dsDNA and MTS assays and the osteointegration was preliminarily tested in vivo on Wistar rats by filling iatrogenic bone defect in femoral bone. The new bone substitute was doped with 20-170 ppm of SeNPs with the size of about 100 nm and antibacterial properties on Staphylococcus aureus (SA) strain and its methicillin-resistant form (MRSA) were evaluated by disk diffusion method.
