title: Gamma-glutamyltaurine has potent and long-lasting antiepileptic action as demonstrated by intra-amygdaloid injection in amygdala-kindled rats.
abstract: Intra-amygdaloid injections of gamma-glutamyltaurine, a recently identified brain dipeptide, strongly suppressed seizures in amygdala-kindled rats stimulated with intensities 10 or 50 microA above the generalized seizure triggering threshold (mean 82 microA). The suppressive effect persisted as long as 3 days. Taurine had relatively weak suppressive effects. Thus gamma-glutamyltaurine seems much more potent than taurine in the suppression of epileptic seizures when injected directly into the kindling site.
