Abstract

Objective: Transplantation, nephron sparing surgery, or renal vascular surgery, where renal blood flow is interrupted called as renal ischemia. Reperfusion is necessary for re-oxygenation of ischemic tissue. However, reperfusion is known to cause additional cellular damage. Sildenafil citrate is the first-found phosphodiesterase type 5 (PDE5) inhibitor. In this study; Sildenafil citrate in the early stages of experimental kidney ischemia-reperfusion injury. Material and Methods: Twenty-eight Wistar rats were gathered in to 4 groups (n=7) Serum samples were taken from each subject for measurement of Malondialdehyde (MDA) and creatine before transaction. We perform all rats right nephrectomy. In group 1 (sham group) rats was not take sildenafil and was not perform ischemia procedure. In group 2 (sildenafil group;) rats only take orally sildenafil. In group 3 (Ischemia group) micro vascular clamp placed left renal artery for 45 min. There was not take sildenafil. In group 4 (treatment group) micro vascular clamp located left renal artery and rats take orally sildenafil. After 4 hours ischemia time, blood samples were taken to measure serum creatine and MDA. And then all animals were sacrificed. Results: There was no statistical difference among groups for MDA and creatine levels. Also statistical difference among groups was not detect for histopathological assessment. Conclusion: Sildenafil citrate claimed that it has positive effect for ischemia reperfusion damage in long term use. In our study, statistically meaning difference is not detected in tissue MDA, serum MDA and creatine levels. Meaning difference among groups is not observed in still histopathological assess. As a result; we think that sildenafil citrate has no therapeutic effect in the early period of renal ischemia reperfusion injury.

Özet

Amaç: Renal iskemi; transplantasyon, nefron koruyucu cerrahi ya da renal vasküler cerrahi gibi böbrek kan akımının kesildiği durumlarda gözlenmektedir. İskemik dokunun reoksijenizasyonu için yeniden kanlanma gereklidir. Bununla birlikte yeniden kanlanmanın da ek hücresel hasar oluşturduğu bilinmektedir. Sildenafil sitrat ilk bulunan fosfodiesteraz 5 (PDE5) inhibitörüdür. Bu çalışmada; sildenafil sitratın deneysel olarak oluşturulan böbrek iskemi yeniden kanlanma hasarının erken döneminde olası koruyucu etkilerini araştırmayı amaçladık. Gereç ve Yöntem: 28 adet Wistar rat 4 gruba ayırıldı (n=7). Cerrahi işlem öncesi malondialdehit (MDA) ve kreatin ölçümü için serum örnekleri alındı. Anestezi uygulaması sonrası ratlara orta hat laparatomi sonrası sağ nefrektomi yapıldı. Sham grubu ratların sol böbrek gerota fasyası açıldı ve ek bir işlem yapılmadı. Sildenafil grubu orogastrik gavaj ile 2.5 mg/kg sildenafil oral olarak verildi. İskemi grubunda sol renal artere mikrovasküler klemp konuldu ve 45 dk.’lık renal iskemi oluşturuldu. Grup 4’deki ratlara (tedavi grubu) orogastrik gavaj ile 2.5 mg/kg sildenafil oral olarak verildi ve sol renal artere mikrovasküler klemp konularak 45 dk’lık renal iskemi oluşturuldu. Dört saatlik yeniden kanlanma sonrası, tüm ratlardan tekrar serum örnekleri alındı ve ratlar sakrifiye edilerek sol böbrekleri histopatolojik incelemeye alındı. Bulgular: Gruplar arasında; serum MDA ve serum kreatin ve doku MDA ölçümleri açısından bakıldığında istatistiksel anlamlı fark saptanmadı (p>0.05). Histopatolojik olarak gruplar arasında fark yoktu. Sonuç: İskemi sonrası doku MDA seviyeleri artmış, iskemi öncesi ve sonrası ölçülen serum MDA seviyelerinde değişiklik olmamıştır. Oral yoldan uygulanan sildenafil sitratın kısa dönem uygulamada doku MDA seviyelerinde azalmaya ve iskemi yeniden kanlanma hasarının engellenmesine etkisi yoktur.
