[Ultrastructure of the nuclei of neurons and glial cells of the cerebral cortex during experimental alcoholic intoxication].

Nuclear ultrastructure of neurons and glial cells of the rat sensomotor cortex was studied under chronic alcoholic intoxication. During 24 h the animals drank up about 10 ml of 20 degrees alcohol. In the course of prolonged alcoholic intoxication there occurred processes leading to deformation of the nuclei of neurons and glial cells and to the deficiency of nuclear and cytoplasmic substances. These changes are regarded as an atrophic process responsible for the corrugation of the nucleus and diminution of the cell size.
