[Experimental models of epilepsy].
BACKGROUND
An epileptic seizure is a clinical event and epilepsy is rather a group of symptoms than a disease. The main features all epilepsies have in common include, spontaneous occurrence, repetitiveness, and ictal correlation within the EEG. Epilepsies are manifested with distinct EEG changes, requiring exact clinical definition and consequential treatment. Current data show that 1% of the world's population (approximately 50 million people) suffers from epilepsy, with 25% of patients bpeing refractory to therapy and requiring search for new substances in order to decrease EEG and behavioral manifestations of epilepsies.


METHODS
In regard to discovery and testing of anticonvulsant substances the best results were achieved by implementation of experimental models. Animal models of epilepsy are useful in acquiring basic knowledge regarding pathogenesis, neurotransmitters (glutamate), receptors (NMDA/AIPA/kainate), propagation of epileptic seizures and preclinical assessment of antiepileptics (competitive and non-competitive NMDA antagonists).


CONCLUSIONS
In our lab, we have developed a pharmacologic model of a (metaphit, NMDA and remacemide-cilastatin) generalized, reflex, and audiogenic epilepsy. The model is suitable for testing various anticonvulsant substances (e.g. APH, A4P, CPP, Mk-801) and potential antiepileptics (e.g. DSIP, its tetra- and octaanalogues).
