The aim of this study was to quantitatively investigate the chronic ethanol-induced cerebral metabolic changes in various regions of the rat brain, using the proton HR-MAS NMR spectroscopy technique. Our results showed that the levels of 2 to 7 metabolites were significantly altered in five brain regions of the ethanol-treated group, compared to the control group. Our key finding is that the Glu/tCr and Cho/tCr ratio levels showed the most significant differences in the thalamus of the rat brain. These increased metabolic ratio levels of the thalamus could be utilized as the key marker in the human chronic alcoholism.
