    Ultrastructural stereological analysis of the liver of Muridae from regions with various levels of anthropogenic pollution (1996)

    Notes: Abstract Ultrastructural stereological analysis revealed the fundamental reorganization of hepatocytes in Muridae from natural ecosystems exposed to anthropogenic factors. An appreciable decrease of the volume density of mitochondria and granular endoplasmic reticulum was associated with a many-fold increase of the volume density of glycogen. The detected hepatocyte glycogenosis was characterized by a redistribution of organelles and the formation of large depots of glycogen with reduced electron density.

    Morphofunctional reorganization of the myocardium of mouse-like rodents in regions with various anthropogenic contamination levels (1999)

    Notes: Abstract Morphofunctional analysis (morphological and stereological) revealed stereotypic morphofunctional reactions (hemodynamic disturbances accompanied by considerable cardiomyocyte degeneration) in the myocardium of common field mice and common voles from various Altai regions. Changes in the capillary surface-volume ratio and the stroma/parenchyma volume ratio are typical of tissue reorganization of the myocardium. The nature of these changes depends on the level and type of contamination.

    Structural features of acute focal metabolic injuries to somatic muscle fibers caused by dimethylparaphenylenediamine (1999)
    Springer
    Bulletin of experimental biology and medicine 127 (1999), S. 640-644

    ISSN: 1573-8221
    Keywords: metabolic injuries ; somatic muscles ; polarization microscopy

    Notes: Abstract The pathological picture of an acute disorder of cell metabolism caused by dimethylparaphenylenediamine consists of typical focal reactions of striated muscles to injury: myofibril contractures and intracellular myocytolysis. Analysis of the pathological process demonstrates the time course of contracture injuries as a succession of overcontracture (first-third degree contractures) and necrobiotic phases (fourth degree contracture), followed by lump degradation and macrophagal resorption. Two polar types of contractures are clearly differentiated by the size, shape and structural and metabolic characteristics of target fibers: “ribbons“ and ”medallions”. Disappearance of Z strips, disaggregation, disorientation, and fragmentation of myofibrils are typical of intracellular myocytolysis. The observed changes form the morphological basis for acute disease of striated muscles.

    General pathological processes in somatic muscles in W/SSM rats with genetically determined metabolic myopathy (1998)
    Springer
    Bulletin of experimental biology and medicine 126 (1998), S. 846-851

    ISSN: 1573-8221
    Keywords: somatic muscles ; metabolic myopathy ; W/SSM rats ; polarization and electron microscopy

    Topics: Biology , Medicine
    Notes: Abstract Hypertrophy, atrophy, and dystrophy, which reflect the balance between alterative and compensatory-adaptive processes at all levels of structural organization, predominate among structural changes in W/SSM rats with metabolic myopathy under conditions of progressive chronic disorders of cellular homeostasis. Primary universal reactions of striated muscles to damage (myofibril contractures and intracellular myocytolysis) are observed at the ultrastructural level. Increased incidence of focal changes and the time course of morphological and stereological parameters in a constantly functioning organ (diaphragm) indicate that working muscle fibers are most susceptible to injury.
