title: Protective effects of GABAergic drugs and other anticonvulsants in lithium-pilocarpine-induced status epilepticus.
abstract: Administration of subconvulsive dose of pilocarpine (30 mg/kg s.c.) to rats pretreated with lithium chloride (3 meq/kg i.p.) produced a state of status epilepticus in animals. The animals showed characteristic symptoms of generalized convulsions, wet dog shakes (WDS), forelimb clonus and falling back. The symptoms of status epilepticus (SE) developed within 26.8 +/- 3.6 min after administering pilocarpine and these symptoms continued uninterrupted. The phenomenon was totally reproducible, with a consistent latency of onset of seizures and a high mortality rate. The symptoms were blocked by atropine, scopolamine and the GABAergic agents GABA, sodium valproate, (+)-baclofen and clonazepam when given prior to pilocarpine, but not when administered 30 min after pilocarpine administration.
