AB  - Nanomaterials are nowadays widely used in various fields of biomedicine. Before the application of biomaterials they have to be tested and fulfill some criteria. The first tests that should be performed after synthesis of some new nanomaterial with potential application in biomedical fields are biocompatibility tests. The aim of this study was to examine the influence of nanomaterial calcium phosphate/poly-(dl-lactide-co-glycolide) (CP/PLGA) on proliferation and adherence of HeLa cells in culture. For both proliferation and adherence examination, cells were treated with suspension of nanomaterial CP/PLGA at concentrations 5, 50 and 500 µg/mL, made in cell culture medium. There were four different types of treatment: (1) cells incubated with CP/PLGA for 3 days; (2) cells incubated with CP/PLGA for 6 days; (3) cells incubated first with CP/PLGA for 3 days and then for the next 3 days with medium and (4) cells incubated first with medium for 3 days and then for the next 3 days with CP/PLGA. Three days after incubation of HeLa cells with different concentrations of CP/PLGA nanoparticles’ suspension, the concentration of 5 µg/mL had mild inhibitory effect on proliferation. Increasing CP/PLGA concentration, there was stimulatory effect on cells’ proliferation. With prolonged incubation period, this dose dependence is lost. The highest adherence of HeLa cells was observed when cells were incubated with the highest examined concentration of CP/PLGA suspension, in both 3-day and 6-day incubation period. Based on the results obtained in our study, we can conclude that the effect of the suspension of nanomaterial CP/PLGA on proliferation and adherence of HeLa cells depends on the duration of incubation with the cells as well as the material concentration and type of the treatment.

AB  - A review of recent advances in instrumental methods and techniques for structural and physicochemical characterization of biomaterials and bone tissue is presented in this paper. In recent years, biomaterials attracted great attention primarily because of the wide range of biomedical applications. This paper focuses on the practical aspects of instrumental methods and techniques that were most often applied (X-ray methods, vibrational spectroscopy (IR and Raman), magnetic-resonance spectroscopy (NMR and ESR), mass spectrometry (MS), atomic absorption spectrometry (AAS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES), thermogravimetry (TG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC), scanning electron microscopy (SEM), transmission electron microscopy (TEM)) in the structural investigation and physicochemical characterization of biomaterials and bone tissue. The application of some other physicochemical methods was also discussed. Hands-on information is provided about these valuable research tools, emphasizing practical aspects such as typical measurement conditions, their limitations and advantages, interpretation of results and practical applications.

AB  - The influence of glucocorticoids on the composition and mineral/organic content of the mandible in tested animals after recovery and healing phase was investigated in this work. The results of FTIR analysis demonstrated that bone tissue composition was changed after glucocorticoid treatment. The increase of calcium, magnesium, phosphorus content and mineral part of bones was statistically significant in recovery phase and in treatment phase that included calcitonin and thymus extract. Some changes also happened in the organic part of the matrix, as indicated by intensity changes for already present IR bands and the appearance of new IR bands in the region 3500–1300 cm−1.
