We determined regional concentrations of excitatory and inhibitory amino acids in pentylenetetrazol (PTZ) kindling and kindled rat brains in order to investigate the mechanisms responsible for the PTZ kindling process and kindled state. Compared with control rats, PTZ kindling rats had significantly higher concentrations of aspartate in the striatum and the temporal cortex 24 h after the 14th injection of PTZ. Glutamate and GABA concentrations were also significantly higher in the brainstem of PTZ kindling rats 24 h after the 14th injection of PTZ. These findings suggest that the striatum and temporal cortex may participate in a pathway for propagation of the PTZ kindling process, and that the brainstem may be a primary site of PTZ kindling epileptogenesis or a part of the pathways for propagation. On the other hand, the concentrations of amino acids in PTZ kindled rats and controls did not differ 4 weeks after the 14th injection. This suggests that the alterations we detected in amino acid metabolism are not related to retention of the PTZ kindled state, and that some other mechanism for it must exist.
