[Proliferative processes in nerve tissue culture under the action of ethanol]

The authors describe the ultrastructure of an organotypic culture of rat brain cortex exposed to small doses of ethanol. It is shown that the small dose of alcohol (0.5% ethanol) present in the nutrient medium induced proliferation of cytoplasmic membrane structure: hyperplasia of the endoplasmic reticulum with the formation of concentrically located membranes; an increase of the number and size of mitochondria was accompanied by the appearance of the giant, atypical forms of mitochondria; proliferation of vesicular components of Golgi's laminar complex.
