Research consist in studing cyto-and fibroarchitectonics of the human cerebral cortex (8, 10, 32/10, 44 and 45 frontal areas). Informative parameters of ansemble postnatal features in cortical organizations for studying at cellular-population level is established. They have included dimensional parameters of neural groupings at layer III and a parity of specific neuronal and fibrous volumes. It is shown, that associative fields 44, 45, 10 in lateral frontal zones is the most long develop in ontogenesis. Especially important structural transformations to them carry staged character and are marked on the first year of a life, and also by 3, 6-7, 10 and 13-14 years.

The results of clinical and experimental morphological studies of regenerates forming after replacement of large defects of the abdominal wall and tibia with implants from different materials (polytetrafluoroethylene, reperene, prolene, titanium, and titanium nickelide) are analyzed. Study of the regenerate histology and fibroarchitectonics has shown good prospects of mesh constructions from titanium nickelide for effective surgical repair of these defects. The use of this implant seems to be theoretically well-based and promising, particularly under conditions of suppurative infection and low individual reparative regenerative potential.

The purpose of the investigation was the study of structural changes connective tissue biomaterials after different combinations of their radiation sterilization, physico-chemical treatment and conservation. Using a complex of histological methods (polarization microscopy of unstained sections, van Gieson's stain, scanning electron microscopy), an analysis was performed to detect the structural changes in tendons and dermis which underwent various physico-chemical treatment and subjected to the radiation sterilization using different types (3- radiation and fast-moving electron stream) and doses (1.5, 2.

Brains from 74 children aged from birth to 12 years were used to study fibroarchitectonic characteristics in topographically and functional diverse cortical zones (the temporal-parietal-occipital subregion, occipital, precentral, postcentral, and frontal areas) of the cerebral cortex; children aged up to 12 months were studied on the basis of one-month age intervals. Studies were performed by computer analysis of optical images on frontal sections stained with Nissl cresyl violet and silver nitrate impregnation by the modified Peters method. Data on the rate of increase in the thickness of radial bundles of fibers, the distances between bundles, and the age dynamics of the ratios of the specific volumes of neurons and fibers in fields 3, 4p, 6op, 17, 19, 37ac, 44, and 32/10 were obtained.

The peculiarities of fibroarchitectonics in topographically and functionally distinct cortical zones (including temporo-parieto-occipital subarea, occipital, pre-, postcentral, and frontal areas) were studied in the brain specimens of 74 children of different ages (from birth to 12 years) taken with yearly intervals, while those in the first year of life--with monthly intervals. Frontal sections stained with Nissl, Peters and Golgi methods were studied using computer analysis of optical images. The data were obtained on the increment rates of radial fiber fascicles' thickness, distances between fascicles and age dynamics of ratios of volume densities of neurons and fibers in areas 3, 4p, 6op, 17, 19, 37ac, 44 and 32/10.
