title: gamma-D-Glutamylaminomethylsulphonic acid (GAMS), a kainate and quisqualate antagonist, prevents sound-induced seizures in DBA/2 mice.
abstract: The effect of gamma-D-glutamylaminomethylsulphonic acid (GAMS) on sound-induced seizures has been assessed in DBA/2 mice. All phases of the seizure response are suppressed following intracerebroventricular injection (ED50 values: 0.077 mumol for tonic seizure, 0.132 mumol for wild running) or intraperitoneal injection (ED50: 1.21 mmol/kg for tonic seizure, 4.95 mmol/kg for wild running). The results are discussed in relation to the involvement of 'kainate' and 'quisqualate' receptors in the generation and propagation of seizures.
