Sıçanda stres ile uyarılan mide ülserinde simvastatin’in etkisi

Amaç: Bu çalışmada sıçanlarda stres ile uyarılan mide ülserinde simvastatin’in (SİM) olası koruyucu etkisini değerlendirmek amaçlanmıştır. Gereç ve Yöntem: Sprague-Dawley sıçanlarda (250-300 gr) soğuk-kısıtlama stres uygulaması ile mide ülseri oluşturuldu. Stres öncesi 21 gün süreyle SİM (10 mg/kg/day; oral yolla) veya fizyolojik tuzlu su (1 ml; oral yolla) uygulandı. Bir grup sıçan 21. günde SİM öncesi selektif olmayan nitrik oksit sentaz (NOS) inhibitörü L-NAME (50 mg/kg; intraperitoneal) veya selektif olmayan siklooksijenaz (COX) inhibitörü indometazin (İndo; 5 mg/kg; subkutan) verildi. Mideler makroskopik ve mikroskopik olarak incelendi ve biyokimyasal analizler için saklandı. Bulgular: Stres grubunda lezyonların şiddeti SİM ile azaldı ancak L-NAME veya İndo ile anlamlı bir değişiklik göstermedi. Stres mide miyeloperoksidaz aktivitesini kontrol düzeyine kıyasla artırdı (p
