“…Предложен целый ряд биокера-мических заметителей костной ткани на основе кальцийфосфатов: гидро- ксиапатита, β-трикальцийфосфата и их композитов [14,20,21,48,56,67]. Среди указанной группы замести-телей чаще всего встречается гидрок-сиапатит, который является неоргани-ческим соединением, чей химический состав подобен составу минерального матрикса костной ткани [52].…”

Objective. To perform comparative analysis of osseointegration of bioceramic alumina-based granules, hydroxyapatitebased granules, and granules of deproteinized bone tissue. Material and Methods. The experiment was conducted on 52 adult male Kyoto-Wistar laboratory rats weighing 350 to 520 g. Animals were divided into five matched groups, which differed only in the type of implanted material. Granules were implanted in lumbar vertebral bodies and in distal right femur of each laboratory animal. Two months after surgery animals were euthanized with subsequent tissue sampling for morphological studies. Results. Examination of specimens from groups with implantation of alumina granules revealed the formed trabecular bone with evidence for remodeling. Bone tissue filled the space between granules fitting closely to their surfaces. There was no connective tissue capsule on the border between the bone tissue and alumina granules. Conclusion. Bioceramic alumina-based granules in the form of cylinders with a through inner channel have high strength surpassing that of analogs and ability for osseointegration close to that of hydroxyapatite and deproteinized bone granules.

The chemically treated Labeo rohita scale is used for synthesizing hydroxyapatite (HAp) biomaterials. Thermogravimetric and differential thermal analyses of fish scale materials reveal the different phase changes with temperature and find out the suitable calcination temperatures. The composition and structures of wet ball-milled calcined HAp powders are characterized by Fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis (EDX). The EDX as well as chemical analysis of fish scale-derived apatite materials confirms that the Ca/P ratio is 1.71. The compressive stress, hardness and porosity have been evaluated on sintered HAp biomaterials. The cell attachment on HAp surfaces, cytotoxicity evaluation and MTT assay, which are carried out in RAW macrophage-like cell line media demonstrate good biocompatibility. The histological analysis also supports the bioaffinity of processed HAp biomaterials in Wistar rat model for investigating the contact reaction and stability at the artificial or natural prosthesis interface.
