[Brain acetaldehyde and ethanol: method of determination and diagnostic significance in ethanol poisoning].

The content of ethanol and acetaldehyde in the limbic cortex and reticular formation of the brain was measured by gas-liquid chromatography in lethal ethanol poisoning. The content of acetaldehyde was significantly increased in the gyrus cinguli of the brain. Lethal poisonings occurred during any stage of ethanol intoxication. The data characterizing individual ethanol tolerance were obtained, which can be used for differential diagnosis of ethanol poisoning in practical forensic medicine.
