title: Effects evoked by pentamethylenetetrazol-induced seizures upon N-acetylaspartate and N-acetylaspartylglutamate levels in different regions of the rat neuraxis.
abstract: We have examined the effects evoked by pentamethylenetetrazol (PTZ)-induced seizures upon the concentration of N-acetylaspartate (NAA) and of N-acetylaspartylglutamate (NAAG) in the forebrain, brainstem and spinal cord of rats. We observed a significant decrease of both NAA and NAAG in each one of the studied regions. These findings are consistent with an inhibitory role proposed in CNS for NAA and NAAG.
