This study was aimed to investigate the cerebral neurochemical effects of long-term alcohol exposure on the adolescent rat frontal cortex. Our results show that GPC+PCh, Ins, Glx concentrations and (GPC+PCh)/NAA levels were significantly differed in frontal cortex of ethanol group. In particular, GPC+PCh concentrations and (GPC+PCh)/NAA levels showed most significant differences in ethanol group. Increased GPC+PCh concentrations and (GPC+PCh)/NAA levels may indicate that increased turnover of phosphatidylcholine and/or changed adaptive mechanism in frontal cortex of rat brain. Therefore, increased GPC+PCh concentrations and (GPC+PCh)/NAA ratio levels of frontal cortex might be utilized as key marker in long-term adolescent alcohol intoxication.
