Abstract
The development of pentylenetetrazol (PTZ) kindling has been controversial, authors confirmed the development of kindling phenomenon in experimental rats following every second or third day intraperitoneal administration of PTZ(20-25mg/kg) to experimental rats and same amount of saline to control rats. The developmental stage of motor seizure could be categorized into five stages (stage I ; clonic seizure of face and neck, stage II ; clonic seizure of face, neck and forelimbs, stage III ; clonic seizure of forelimbs and body with brief rearing, stage IV ; falling and generalized clonic seizure, stage V ; falling and generalized tonic-clonic seizure with tonic extension of hindlimbs). Linear regression analysis showed that the stages of motor seizure were increased with the number of PTZ injections (Y=0.1361X + 0.1943, p < 0.05). The persistence of kindling state was also observed after a 5-months pause of PTZ injection. This study suggested that PTZ kindling model in rats could be a good animal model of generalized epilepsy.
