DİYABETİK SIÇAN MODELİNDE AMİNOGUANİDİN TEDAVİSİNİN EKSTRASELÜLER MATRİKS PROTEİN EKSPRESYONU VE KOLLOJEN YAPISINA ETKİSİ
Abstract
Amaç: Diyabete bağlı cilt değişiklikleri klinik olarak normal durumdayken başlamaktadır ve metabolik kontrolle doğru orantılıdır. Bu çalışmanın amacı diyabetik sıçan modelinde aminoguanidin tedavisinin ekstraselüler matriks protein ekspresyonu ve kollojen yapısına etkisini incelemektir.
Yöntem: Bu amaçla streptozosin ile diyabet oluşturulmuş 12 sıçandan 6 tanesine içme suyuna aminoguanidin eklenerek, diğerleri ise ilaçsız olarak 8 hafta boyunca izlendi. Altı sıçan da sağlıklı kontrol olarak takip edildi. Takip süresi sonunda cilt dokuları alınarak incelendi.
Bulgular: Işık mikroskopisinde diyabetik sıçanlarda bazal membranda kalınlaşma, dermal ödem, vasküler membran kalınlaşması, endotel proliferasyonu ve perivasküler dejenerasyon gözlendi. İmmünhistokimyasl boyamada kollojen IV ve TGF-β’da azalma görüldü. Tüm bu değişikliklerin aminoguanidin tedavisi ile oluşmadığı izlendi.
Sonuç: Bu çalışma diyabetin klinik olarak normal görülen ciltte mikroskopik bozukluklar oluşturduğunu doğrulamaktadır. Aminoguanidin tedavisi cilt değişikliklerinin gelişimini engellemektedir.
