Abstract | Rats, that develop spontaneously recurrent seizures (SRS rats), were obtained by previous induction of status-epilepticus-linked lesions in the limbic system with kainic acid (KA), applied systemically (10 mg/kg s.c.). The animals treated in this way develop spontaneous recurrent seizures in several weeks. The procedure was improved by interrupting the KA-induced status epilepticus with diazepam (5 mg/kg i.m.). In this way the mortality of rats due to seizures was reduced and the number of rats, developing SRS was thus increased by 120 per cent. The response to KA in the SRS rats was qualitatively different as compared to the rats treated by the KA for the first time. The "wet dog shakes" and the epileptic status did not develop and the frequency of recurrent seizures was significantly increased in the KA-treated SRS rats. The pretreatment with diazepam (5 mg/kg i.m.), MK-801 (1 mg/kg i.p.) or scopolamine (10 mg/kg i.p.) decreased the frequency of the KA-induced seizures. The lower dose of scopolamine (1 mg/kg i.p.) was, however, ineffective. Therefore, the KA-induced recurrent seizures in the SRS rats could be a useful model for studying possible antiepileptic drugs. | |
