Özet

Amaç: Bu çalışmanın amacı; sıçanlarda oluşturulan mezenter iskemi-reperfüzyon modelinde intravenöz uygulanan deksmedetomidinin reaktif oksijen ürün düzeyi üzerine etkilerinin araştırılmasıdır. Yöntem: 300-320 g ağırlığında, 28 adet, erkek, Spraque-Dawley cinsi sıçan dört gruba ayrıldı (n:7). Sham operasyonu geçiren iki gruptan; grup 1’deki sıçanlara (Kontrol grup, Grup K) ilaç uygulanmazken grup 2’deki sıçanlara 5 mg/kg/s deksmedetomidin infüzyonu yapıldı. Diğer iki gruba (grup 3 ve 4) süperior mezenter arter ligasyonu ile 30 dk iskemi ve ardından 60 dk reperfüzyon uygulandı (I/R). İskemireperfüzyon sırasında Grup 3’deki (I/R-S) sıçanlara 0.9% NaCl ve grup 4’deki (I/R-D) sıçanlara 5 mg/kg/h deksmedetomidin infüzyonu yapıldı. İleumdan, luminal ve lusigenin kemiluminesans (KL), doku miyeloperoksidaz aktivitesi, malondialdehid (MDA) ve glutatyon seviyesi ölçümleri için doku örnekleri alındı. Bulgular: Luminol KL seviyesi, doku miyeloperoksidaz aktivitesi (p
