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

    Notizen: 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.

    Parenchyma-stroma interactions in the liver of muridae from ecologically contrasting areas (1996)
    Springer
    Bulletin of experimental biology and medicine 122 (1996), S. 731-736

    ISSN: 1573-8221
    Schlagwort(e): technogenic pollution ; long-term consequence ; Muridae

    Thema: Biologie , Medizin
    Notizen: Abstract Changes in the spatial organization of hepatic tissue are demonstrated in Muridae caught in biocenoses with heavy technogenic pollution. The hemocapillary to hepatocyte volume ratio and, consequently, the stroma to parenchyma volume ratio are found to be significantly decreased. The changes are more pronounced in field-mice, which makes them a more preferable model for the assessment of long-term consequences of anthropogenic interventions, specifically, of radiation pollution.

    Tissue reorganization of rat adrenal cortex induced by hypoxia and its correction with nandrolone (1999)
    Springer
    Bulletin of experimental biology and medicine 128 (1999), S. 754-759 
    Details
    ISSN: 1573-8221
    Schlagwort(e): adrenal cortex ; hypoxia ; nandrolone ; morphology ; stereology

    Notizen: Abstract Acute hypoxia has a pronounced catabolic effect, whereas repeated hypoxic episodes promote hypertrophy of the adrenal cortex. Steroid hyperproduction caused by stress reaction after single hypoxic episode persists after repeated hypoxic episodes. The relations between vessels and parenchyma play the key role in spatial reorganization of the adrenal cortex. Increased volume and surface-volume ratios between sinusoids and adrenocorticocytes point to the enhancement of transcapillary exchange and can be regarded as an adaptive compensatory reaction on the tissue level. Nandrolone decreases antianabolic and stress effects of hypoxia, thus potentiating compensatory adaptive reactions both after single and repeated hypoxic episodes.
