The Effect Of Flunarizine On Penicillin Model Epilepsy İn Rats

Year 1999, Volume: 16 Issue: 4, - , 23.12.2009

Abstract

Epilepsy is one of the most important neurological diseases. Calcium ions have an important role on the regulation of cellular functions. It is accepted that calcium flux into the cell is the first step of epileptic neuronal events. In present study, the effect of flu-narizine on experimental model epilepsy induced by intracortical (i.e.) penicillin administration was investigated. The left cerebral cortex was exposed by craniotomy in anaesthetised rats. The epileptic focus was produced by injection of penicillin G potassium (500 units) into the somatomotor cortex. Following the epileptiform activity reached maximum frequency and amplitude, flunarizine was injected into the same area by Hamilton mikroinjector. Before flunarizine administration, the average frequency of spikes was 21.1±1.9/min and the average amplitude of spikes was 1080±65 pV. Microinjection of flunarizine (10, 100 pM) into the same area caused an inhibition for 3-4 minutes in elect-rocorticograms (ECoG) (p<0.001). But saline did not affect the epileptiform activity (p>0.05). The results of this study suggest that flunarizine may be an anticonvulsant agent in treatment of epilepsy.



Sıçanlarda Penisilin Modeli Epilepsiye Flunarizinin Etkisi
Epilepsi en önemli nörolojik hastalıklardan birisidir. Kalsiyum iyonları hücresel fonksiyonların düzenlenmesinde önemli rol oynarlar. Serbest kalsiyum iyonlarının hücre içine girişi epileptik nöronal olayların ilk basamağı olarak kabul edilir. Sunulan çalışmada, intrakortikal (i.e.) penisilin uygulamasıyla oluşturulan deneysel model epilepsiye flunarizinin etkisi araştırıldı. Anestezili sıçanlarda sol serebral korteks kraniotomi ile açıldı. Somatomotor kortekse penisilin G potasyum (500 ünite) verilerek epileptik odak oluşturuldu. Epileptiform aktivite maksimum frekans ve amplitude eriştikten sonra, aynı bölgeye Hamilton mikroenjektörü ile flunarizin enjekte edildi. Flunarizin uygulanmadan önceki ortalama spike sayısı 21.1±1.9/dk ve ortalama spike yüksekliği 1080±65 uV idi. Aynı bölgeye flunarizin mikr o enjeksiyonu (10, 100 pM) elektrokortikogramda (EcoG) 3-4 dakika süreyle inhibisyona neden oldu (p<0.001). Oysa serum fizyolojik epileptiform ak-tiviteyi etkilemedi (p>0.05). Çalışmanın sonuçları flunarizinin epilepsi tedavisinde etkili bir antikonvulsan ajan olabileceğini göstermektedir.
