title: Synergistic anticonvulsant effects of a GABA agonist and glycine.
abstract: Administration of muscimol to mice in subcutaneous doses between 0.34 and 1.25 mg/kg produced partial protection against 3-mercaptopropionic acid (MPA)-induced seizures. Glycine at a dose of 750 mg/kg (10 mmol/kg) protected 20% of the animals 45 min after its administration. Combined treatment with the two compounds gave a near to complete protection against MPA-induced seizures. These observations suggest that the concomitant enhancement of glycinergic and GABAergic activities amplify the anticonvulsant effect of these neuronal systems against seizures induced by impairment of GABA-mediated transmission.
