title: [Morphometric characteristic of some structures of the human brain in normal conditions and in acute ethanol intoxication].
abstract: In order to establish the neuro-stromal interrelations in the human brain under normal conditions and after extreme influences, different parts of this organ were studied in 14 persons who died suddenly and in 20 persons who died of ethyl alcohol poisoning. A complex of histological, histochemical, planimetric and morphometric methods were used. The specific area of normal neurocytes was shown to be the largest in the medulla oblongata, while that one of the fibers--in the cerebral cortex. Vascularization of the latter is minimal, being much higher in the medulla oblongata. In alcohol intoxication, the area, occupied by neurocytes, was decreased in the cerebral cortex, thalamus and cerebellum due to the destruction of some portion of these cells. In the medulla oblongata neurocytes appear to be more resistant to ethanol. The capillary diameter in the brain areas studied decreased because of the drop in the tone of cerebral arteries, but the number of these vessels per standard area of section was increased as a result of compensatory opening of reserve capillaries.
