Abstract

Erythropoietin (Epo), a cytokine hormone produced in the kidney, promotes the formation of red blood cells in the bone marrow. The penicillin-induced epilepsy model is a commonly used experimental model for epilepsy research. The present study was conducted to elucidate the effect of Epo on penicillin-G (500 IU/2.5 µl dose, intracortically (i.c)) -induced epileptiform activity in anesthetized adult Wistar-Albino rats (n=39). The animals were randomly divided into four groups as three treatment groups and a control group (no drug application). Rats in groups 1, 2 and 3 were intraperitoneally administered 2.000, 4.000 and 6.000 IU Epo/kg, respectively. The effects on penicillin G induced epilepsy were compared across groups using electrocorticography. Epo at 2.000 IU/kg did not cause a significant change (P>0.05) in epileptiform spike-wave activity (number/min) and/or amplitude (µV) values, whereas the average number of spike-waves per minute and seizure severity decreased significantly in the 4.000 and 6.000 IU/kg Epo groups compared with the control (P<0.05). Consequently, the results of the present study show that administration of Epo has a dosedependent antiepileptic effect in penicillin induced model of epilepsy in rats.

Özet

Eritropoietin (Epo), böbreklerde sentezlenen ve kemik iliğinde eritrosit üretimini sağlayan bir sitokin hormonudur. Deneysel epilepsi araştırmalarında, genel olarak penisilin ile oluşturulan epilepsi modeli kullanılmaktadır. Çalışmamızda, anestezi altındaki yetişkin WistarAlbino türü sıçanlarda (n=39), Penisilin-G (intrakortikal (i.c) olarak, 500 I.U/2.5 µl dozda) ile oluşturulmuş epileptik aktivite üzerine Epo'nun etkileri araştırıldı. Sıçanlar, üç tedavi grubu ve bir kontrol grubu (ilaç uygulanmadı) olarak rastgele dört farklı gruba ayrıldı. Grup 1, 2 ve 3'de bulunan sıçanlara, intraperitonal olarak sırayla 2.000, 4.000 and 6.000 IU Epo/kg'lık dozlarda Epo uygulandı. Gruplar arasında, penisilin G ile oluşturulan epilepsi üzerine Epo'nun etkisi elektrokortikografi kullanılarak karşılaştırıldı. Kontrol grubu ile Epo grubu karşılaştırıldığında, 4.000 ve 6.000 IU/kg Epo uygulaması, dakika başına diken dalgaların ve dikenlerin ortalama sayısı ve nöbet şiddetini anlamlı (P 0.05). Sonuç olarak yapılan çalışma, Epo'nun sıçanlarda penisilin ile oluşturulmuş deneysel epilepsi modeli üzerine uygulanmasının, doz bağımlı antiepileptik etkiye neden olduğu ortaya çıkarmıştır.
