Abstract

Purpose: To investigate the possible vascular endothelial growth factor inhibition effects of edaravone and to compare bevacizumab on diabetic retinopathy in streptozotocin-induced diabetic rats.Materials and Methods: Thirty-six adult male Sprague Dawley rats were used in the study. Diabetes was induced with streptozotocin (60mg/kg). After 4 weeks of treatment, the rats were euthanized and blood samples were collected for vascular endothelial growth factor assay.Additionally, enucleation was performed for vascular endothelial growth factor immunohistochemistry and outer nuclear layer measurements.Results: Treatments with both bevacizumab and edaravone signifi cantly decreased outer nuclear layer thickness and retinal vascular endothelialgrowth factor expression compared to serum physiologic groups. In addition, plasma vascular endothelial growth factor levels were signifi cantlyreduced in both bevacizumab and edaravone treated groups compared to the serum physiologic group.Conclusions: Intraperitoneal and intravitreal bevacizumab and intraperitoneal ederavone could diminish the progression of diabetic retinopathy.These fi ndings suggest that edaravone may become one of the therapeutic candidates of diabetic retinopathy in the future.

Özet

Amaç: Streptozotosin ile diabet oluşturulan sıçanlarda diyabetik retinopatide edaravonun olası vasküler endotelyal growth faktör inhibe edici etkisinin araştırılması ve bevacizumab ile karşılaştırılması. Materyal ve Metod: Bu çalışmada 36 adet Sprague Dawley erkek sıçan kullanılmıştır. Diyabet streptozotosin (60 mg/kg) ile oluşturuldu. Sıçanlara 6 gruba ayrılarak intravitreal veya intraperitoneal olarak edaravone, bevacizumab ve serum fi zyolojik uygulandı. Dört haftalık tedavinin ardından, sıçanlara ötenazi yapıldı ve vasküler endotelyal growth faktör değerlendirmesi için kan örnekleri alındı. Ek olarak, vasküler endotelyal growth faktörün immünhistokimyasal olarak değerlendirilmesi ve dış nükleer tabakanın değerlendirilmesi için enükleasyon yapıldı. Bulgular: Bevacizumab ve edaravone tedavileri ile dış nükleer tabaka kalınlığında ve vasküler endotelyal growth faktör immünhistokimayasal değerlendirmesinde serum fi zyolojik grubu ile karşılaştırıldığında belirgin azalma mevcuttu. Ayrıca, kan vasküler endotelyal growth faktör seviyelerinde bevacizumab ve edaravone ile tedavi edilen gruparda serum fi zyolojik ile tedavi edilen grup ile karşılaştırıldığında belirgin azalma vardı. Sonuç: İntravitreal ve intraperitoneal bevacizumab ile intraperitoneal edaravone diyabetik retinopatinin ilerlemesini yavaşlatabilirler. Bu bulgular edaravonun gelecekte diyabetik retinopati tedavisinde bir aday olabileceğini düşündürtmektedir.
