In experimental animals exposed to hydrogen sulfide-containing gas, electron microscopic study of cerebral cortex indicated the variability in the reaction of layer V neurons: along with neurons demonstrating irreversible damage, some cells with single signs of alteration were found. The reaction of different types of glial cells was also non-uniform.(More)
11]. High concentrations of hydrogen sulfide act as rapidly as cyanide [11]. Poisoning of humans with hydrogen sulfide produces a clinical pattern dominated by psychoneurological symptoms [3, 5, 6]. Hydrogen sulfide, a highly toxic gas, is produced by a number of industries: the metallurgical, cellulose-paper, and other industries; it is formed by the decay(More)
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)
The damaging effect of aluminum ions (Al3+) on the organism is widely investigated in clinics and experiments that indicate its role as a participant in the synthesis of precursors for amyloid proteins and as a potential agent in the ethiology of Alzheimer's disease. It has been shown that Al produces neurotoxic effects. We established that AlCl3 produces(More)
We studied ultrastructural and morphometric characteristics of nerve cells and myelinated fibers in the cerebral cortex after chronic exposure to natural gas containing hydrogen sulfide in low concentrations. Radioisotope assay revealed activation of protein synthesis in nerve cells after chronic exposure to natural hydrogen sulfide-containing gas in low(More)
The possibility and applications of quantitative dry mass and water content mapping using an image analysis of darkfield intensity digitalization were shown on ultrathin freeze-dried cryosections. The distribution map obtained may be further used both for direct measurements of local dry mass and water content under physiological state and pathological(More)
The modern classification of the gastroenteropancreatic endocrine system (GEPES) is presented. Qualitative and quantitative composition of the entero-endocrine system (EES) included in the GEPES is considered, as well as functional role of every type of the cells. The literature data are summarized and the morphology at the light optic and electron(More)
