Abstract

Objective: The aim of this study was to determine the potential, protective effects of amlodipine in an experimental, ischemia-reperfusion (I/R) model in the rabbit small intestine. Materials and Methods: The rabbits were divided into four groups: sham-operated, amlodipine (10 mg/kg) + sham-operated, I/R, and I/R + amlodipine (10 mg/kg) groups. An intestinal I/R model was applied to the rabbits. The superior mesenteric artery was occluded for 1 h with an atraumatic vascular clamp and then was reperfused for 2 h. Animals in the amlodipine and I/R + amlodipine groups received the amlodipine by oral gavage. At the end of the 2-h-reperfusion period, the animals were sacrificed.Results: Pretreatment with amlodipine significantly increased SOD activity and GSH levels to values close to those found in the serum from the I/R group. Rabbits in the I/R group showed high levels of serum MDA. Amlodipine pretreatment significantly reduced the serum MDA levels compared to the I/R group, although the MDA levels in the I/R + amlodipine group were still higher than in the sham-operated group. The I/R damage was ameliorated by amlodipine pretreatment, as evidenced by histopathological analysis.Conclusion: The present study is the first to report an attenuation of I/Rinduced intestinal injury by the systemic administration of amlodipine.

Özet

Amaç: Biz bu çalışmada, tavşan ince barsak iskemi-reperfüzyon (I/R) deneysel modeli üzerine amlodipin'in koruyucu etkisini inceledik. Gereç ve Yöntem: Tavşanlar dört guruba ayrıldı: şam operasyon gurubu, 10mg/kg amlodipin+şam operasyon gurubu, I/R gurubu, I/R+ 10 mg/kg amlodipin gurubu. İntestinal iskemi/reperfüzyon modeli tavşanlara uygulanıldı. Superior mezenterik arter 1 saat sure ile atravmatik vasküler klemp ile klempe edildi sonrasında 2 saat reperfüzyon uygulanıldı. Amlodipin ve amlodipin+I/R guruplarına oral gavaj ile amlodipin verildi. İki saatlik reperfüzyon süresinin sonunda hayvanlar sakrifiye edildi. I/R hasarının amlodipin uygulaması ile düzeldiği histopatolojik analizler ile ispatlandı.Bulgular: Amlodipin uygulaması I/R ‘da serumda bulunan SOD aktivitesi ve GSH seviyesini anlamlı şekilde artırdı. Tavşanlarda intestinal I/R'ında yüksek seviyede MDA gözlendi. Amlodipin uygulaması intestinal I/R bulunan tavşan serumunda MDA aktivite seviyesini anlamlı şekilde düşürürken bu düşüş I/R+amlodipin gurubu control gurubu ile mukayese edildiğinde çok daha fazlaydı.Sonuç: Mevcut çalışma I/R ile oluşan intestinal hasar üzerine amlodipin'in sistemik uygulamasının iyleştirici etkisini gösteren ilk çalışmadır.
