Morphological properties of cells possessing a natural cytotoxic activity obtained from blood of healthy persons have been studied, as well as the process of their interaction with sensitive target-cells (K-562). By means of electron microscopy, during incubation at 37 degrees C, appearance of specific morphological manifestations of cytolytic action of the(More)
Morphine was administered intraperitoneally to Wistar rats at increasing doses from 10 to 60 mg pay during 8 days. Cardiomyocyte damage in the form of myocytolysis and wave-like deformations of muscle fibers prevailed at the level of light microscopy. Microcirculatory alterations were characteristic: stasis, sludge-phenomenon, perivascular and interstitial(More)
The state-of-the-art of classifications of and criteria for cell death in the light of the 2009 recommendations of the Nomenclature Committee on Cell Death is presented as a lecture. Motivation is given for the necessity of using the unified criteria in the description of cell death and more than one study in its verification. The major structural and(More)
We compared conventional method for specimen (cell cultures, tissue specimens) preparation for scanning electron microscopy and a method without sputtering and critical-point drying. OTO-method (osmium-thiocarbohydrazide-osmium) with sample impregnation with hexamethyldisilazane followed by air drying was used as an alternative method. Excellent(More)
We report that the action of the heterodimeric phospholipases A2 (PLA2s) from Vipera nikolskii, which comprises enzymatically active basic subunit and inactive acidic PLA2 homologue, on the lipid bilayer results in the aggregation and stacking of bilayers. These processes are demonstrated using two independent methods (fluorescence spectroscopy and electron(More)
Human embryos with anomalies of brain and spinal cord were studied on 27-35th day of the development. It was established that developmental anomalies were associated with the disturbed formation of neural tube. The reconstruction of three-dimensional brain arrangement of embryos has shown the presence of different variants of nonclosed medullar tori. In(More)
OBJECTIVE To analyze cellular and subcellular disorders in the lung in the presence of HIV-associated tuberculosis. MATERIAL AND METHODS The investigators made a comprehensive morphological examination of 25 autopsy specimens from patients who had died from HIV-associated tuberculosis. Lung pieces from the foci of caseous necrosis at its boundary and(More)
The article deals with the main clinical and instrumental methods of determining severity of chronic arterial insufficiency of the lower extremities, showing possibilities of morphological studies for an accurate diagnosis of the ischaemia degree. Also determined are promising trends of studying the hypoxia-inducible factor (HIF) and vascular endothelial(More)
Schwann cells forming peri-insular glial sheath of the pancreatic islets in some mammals can be involved in the pathogenesis of diabetes mellitus. Human pancreatic cells contain small elongated or oval cells of unknown origin with S100-immunopositive processes. We found that cells with processes located in pancreatic islets of human fetuses and children are(More)
Bronchoalveolar lavage fluid (BALF), broncho- and transbronchial biopsies were examined in Chernobyl wreckers eleven years after the accident. Cytologically and electron-microscopically, there was predominance of alveolar macrophages (AM) with many cytoplasmic foreign bodies containing clear needle-like crystals. Roentgenospectral analysis and laser(More)
