ABSTRACT
The influence of intracisternal administration of antiserum to the neurospecific brain gamma gamma-enolase (aS-gamma gamma) on the consumption of 7.5% ethanol solution by rats was studied. Injection of aS-gamma gamma decreased the ethanol intake by the rats which had been drinking 15% solution of ethanol for 7 months as a single source of liquid. In vitro aS-gamma gamma caused 4-fold inhibition of the gamma gamma-enolase activity while it did not influence the alpha alpha-enolase activity. Intracisternal administration of aS-gamma gamma shifted enolase isoenzyme spectra in the direction of the decrease of gamma gamma-enolase content. It is suggested that the effect of aS-gamma gamma on ethanol consumption is due to inhibition of the activity of gamma gamma-enolase which participates in energy metabolism in neurons.
