title: The calcium carbimide-ethanol interaction: lack of relation between electroencephalographic response and cerebrospinal fluid acetaldehyde.
abstract: Penetration of acetaldehyde into cerebrospinal fluid (CSF) was studied in healthy human volunteers during calcium carbimide-ethanol interaction. CSF was sampled via lumbar puncture and blood from a cubital vein. CSF and blood acetaldehyde concentrations varied from 1 to 41 and from 22 to 138 mumol/l, respectively. The results indicate that acetaldehyde penetrates the human blood-liquor barrier. Computer analysis of electroencephalograms (EEGs) recorded during the interaction showed reduction in alpha activity with a concomitant increase in delta activity. The changes were similar to those previously observed during 'normal' ethanol intoxication.
