AB  - Implantation of a biomaterial is one of the important trends in solving the problem of bone tissue loss. Calcium hydroxiapatite (HAp), as the most representative bone component is a serious candidate for such implantations. The synthetic polymer poly-L-lactide (PLLA) in HAp/PLLA is often used as a polymeric material, with a role in the substitution of bone tissue collagen fibers. Fibers of PLLA may strengthen HAp and its good bioresorption provides space for tissue remodeling. Differences in porosity, microstructure, compressive consistency as well as bioresorbility of HAp/PLLA may be achieved by using PLLA with different molecular weights. In this study HAp/PLLA composites with PLLA of different molecular weights (50,000; 160,000 and 430,000) were implanted in mouse peritoneum in order to examine the influence of the molecular weight of PLLA on morphology changes. Microstructural changes of biomaterial (HAp/PLLA) surface were analyzed one week, three weeks and four months after their implantation using Scanning Electron Microscopy. The results showed a significant difference in tissue reactions on the applied biocomposites, depending on their molecular weight. The most intense proliferation of cells was induced by HAp/PLLA 50,000 compared to HAp/PLLA 430,000 and HAp/PLLA 160,000. In the vicinity of HAp/PLLA 430,000 abundant erythrocytes were observed. The differences in biological reactions on the examined biocomposites are significant for their practical applications. HAp/PLLA composite biomaterials of different types and resorption rates require specific designing and programming to become suitable for particular purposes in an organism.

AB  - Indications exist that paramagnetic calcium phosphates may be able to promote regeneration of bone faster than their regular, diamagnetic counterparts. In this study, analyzed was the influence of paramagnetic cobalt-substituted hydroxyapatite nanoparticles on osteoporotic alveolar bone regeneration in rats. Simultaneously, biocompatibility of the material was tested in vitro, on osteoblastic MC3T3-E1 and epithelial Caco-2 cells in culture. The material was shown to be biocompatible and nontoxic when added to epithelial monolayers in vitro, while it caused a substantial decrease in the cell viability as well as deformation of the cytoskeleton and cell morphology when incubated with the osteoblastic cells. In the course of 6 months after the implantation of the material containing different amounts of cobalt, ranging from 5 to 12 wt%, in the osteoporotic alveolar bone of the lower jaw, the following parameters were investigated: histopathological parameters, alkaline phosphatase and alveolar bone density. The best result in terms of osteoporotic bone tissue regeneration was observed for hydroxyapatite nanoparticles with the largest content of cobalt ions. The histological analysis showed a high level of reparatory ability of the nanoparticulate material implanted in the bone defect, paralleled by a corresponding increase in the alveolar bone density. The combined effect of growth factors from autologous plasma admixed to cobalt-substituted hydroxyapatite was furthermore shown to have a crucial effect on the augmented osteoporotic bone regeneration upon the implantation of the biomaterial investigated in this study.

AB  - Simulated body fluid (SBF) is an artificial fluid which has ionic composition and ionic concentration similar to human blood plasma. Purpose: This paper compares the interaction between the nanomaterial containing calcium phosphate/poly-dl-lactide-co-glycolide (N-CP/PLGA) and SBF, in order to investigate whether and to what extent inorganic ionic composition of human blood plasma leads to the aforementioned changes in the material. Methods: N-CP/PLGA was incubated for 1, 2, 3, and 5 weeks in SBF. The surface of the material was analyzed on SEM-EDS and FTIR spectrometer, while SBF was subjected to pH and electrical conductivity measurement. Results: Our results indicate that dissolution of the polymer component of the material N-CP/PLGA and precipitation of the material similar to hydroxyapatite on its surface are based on the morphologic changes seen in this material. Conclusions: The mechanism of the apatite formation on the bioceramic surface was intensively studied and was considered crucial in designing the new biomaterials. The results obtained in this work indicate that N-CP/PLGA may be a good candidate for application to bone regeneration.

AB  - One of the trends in the treatment of reduced bone density is in oral implantology through the use of new biomaterials with paramagnetic properties. In this in vivo study the effect of Ca /Co-HAp nanoparticles (calcium/cobalt-hydroxiapatite) in the regeneration of the reduced alveolar bone density in experimental animals was examined by analyzing both the biochemical and histochemical markers and through analysis of alveolar bone density. The research was carried out on female Westar rats, aged 6-8 weeks, whom have been implanted nanobiomaterial in reduced alveolar bone density. Good results in regeneration of reduced bone density were achieved in six weeks after implantation of the nanoparticles with paramagnetic properties. Biochemical markers of osteogenesis showed statistically significant rise. Histological analysis revealed high level reparatory skills of the biocomposite implanted in the bone defect, while X-ray analyses evidenced rise of bone density. Implantation of Ca/Co-Hap enables rapid new formation, thus becoming the material of choice for accelerated reduced bone density regeneration.

AB  - Bone tissue reconstruction and reparation is a big challenge in medicine. Biocomposite materials based on hidroxyapatite are widely used in reparation of bone defects. Adult bone marrow-derived stem cells may be considered in two categories: hematopoietic stem cells (HSC) from the bone marrow and mesenchymal stem cells from the bone marrow stroma (BMSC). HSC and BMSC do not only coexist in one organ, but functionally cooperate. BMSC have a critical role in the formation of hematopoietic microenvironment (HME). The aim of this study was to investigate the interactions between bone marrow cells and biocomposites based on HAp/PLLA (hidroxyapatite/poly-L-lactide) after subcutaneous implantation in Balb/c mice. In that purpose, bone marrow cells of Balb/c mice were seeded in HAp/PLLA tubes (15 mm×1,5 mm). The HAp/PLLA tubes with BMC was subcutaneously implanted with a needle into the intrascapsular region of the mouse. Implants were extracted after 2, 6 and 12 weeks. In implants after 2 and 6 weeks we found angiogenesis, collagenogenesis and new bone. Ectopic hematopoiesis was seen in implants after 12 weeks from implantation. As a good scaffold in the role of supporting osteogenesis and hematopoiesis, biocomposites HAp/PLLA can be good bone substitute materials in the bone reparation process. These results showed that the HAp/PLLA scaffold owned biological properties comparable to natural bone.

HAp/PLLA oblikovan je u cevčice (15 mm×1,5 mm) koje su napunjene ćelijama koštane srži miša, a zatim implantirane. Kontrole su bile prokuvane tibije i femuri napunjene na isti način. Implanti su ekstrahovani posle 2, 6 i 12 nedelja i analizirani patohistološki. Angiogeneza i osteogeneza se vide već posle dve nedelje na implantima, što je izraženije na kostima. Vrlo izražena hematopoeza u implantima oba tipa se vidi posle dvanaest nedelja. HAp/PLLA može poslužiti kao matrica za ektopičnu osteogenezu i hematopoezu.

AB  - The need for bone graft materials in osteoreparation is tremendous. Many researches have shown that calcium-phosphate bioceramics have good biocompatibility and osteoconductivity. We used nanocomposite biomaterial calcium phosphate coated with poly (dl-lactide-co-glycolide) or N-CP/DLPLG. The goal of this investigation was to examine weather N-CP/DLPLG has ability to sustain growth of bone marrow cells after subcutaneous implantation in Balb/c mice. For that purpose N-CP/DLPLG implants with and without bone marrow cells (control) were made. Implants were extracted after eight days and eight weeks. In implants loaded with bone marrow cells after eight days and eight weeks we observed fields rich in cells, angiogenesis and collagen genesis. These results showed that N-CP/DLPLG has property of tissue scaffold which sustain bone marrow cells growth and collagen production. This represents a good way for further examination of N-CP/DLPLG as potentional tissue scaffold in osteoreparation.

AB  - Hydroxyapatite (HAp) is biomaterial widely used in the regeneration of bone tissue.
Addition of osteogenic cells to HAp implants may accelerate the bone repair process. The aim of
this study was to investigate how the bone marrow cells (BMCs) loading of porous
hydroxyapatite/poly-L-lactide (HAp/PLLA) act to ectopic osteogenesis. In this purpose
HAp/PLLA with and without BMCs was subcutaneously implanted into BALB/c mice. As a
control served implants from both types which weren’t implanted. Three weeks after
implantation, histological analysis of implants was done. It was observed significant resorption
and induction of collagenogenesis in implanted biomaterials. The structure of new bone was
seen in implants loaded with bone marrow cells.

AB  - Siloxane polimers have been widely used in biomedicine and pharmacy due to their biocompatibility. Hydroxyapatite (HAp) is a natural constituent of bones, and therefore widely used in maxillofacial and orthopedic surgery. HAp itself is amorphous and without elasticity, so its characteristics can be improved when combined with organic polymers. We evaluated the interaction of cells and composites made of polydimethylsiloxane (PDMS) and HAp by scanning electron microscopy (SEM) 10 days after their intraperitoneal implantation into Balb/c mice. Two composites which were different in the quantity of HAp were analyzed. Both of them showed high adhesive characteristics for different cell types. The erythrocytes in cell clusters could be seen on the surface of the composite with higher quantity of HAp.
