title: [Histomorphometric characteristic of human brain in acute alcoholic intoxication].
abstract: Different brain sections were studied in 20 subjects, who died of ethanol intoxication and in 14 subjects who died of injuries of the heart and main vessels, in order to detect histological changes in the brain and for the purpose of defining spatial and quantitative ratios between cerebral tissue structures in alcoholic intoxication. Different histological, stereometric and morphometric tools were made use of. It was demonstrated that, in alcoholic intoxication, there occur severe disorders of the circulation with affection of vessels in the brain; there are also dystrophic and necrotic changes in neurocytes, glial cells and white substance. The square of neurons shrinks due to death of some of them in the cortex of hemispheres, thalamus and cerebellum. As for the medulla, they are more resistant, there, to ethanol. The diameter of capillaries in the studied brain sections diminishes due to a reduced tonus of cerebral arteries; the quantity of such vessels increases within a standard area, which is conditioned by the compensatory opening of reserve capillaries. All this can be important in dealing with issues of thanatogenesis and of forensic medical diagnosis in death of alcoholic intoxication.
