A single-dose tadalafil treatment significantly restored renal CAT activity to the range of controls in the PT group.Conclusion: Although tadalafil did not affect renal oxidative stress induced by partial or complete UUO, elevation of CAT activity to control values in the PT group suggests that increasing doses or duration of tadalafil treatment might be protective for kidneys in UUO

Abstract

Objective: It has been reported that tadalafil, a specific phosphodiesterase-5 (PDE5) inhibitor, has an antioxidant effect besides its well-known vasoactive properties. This study aimed to determine the possible protective effects of tadalafil in managing renal oxidative stress induced by unilateral ureteral obstruction (UUO).Methods: Male Sprague-Dawley rats aged 2.5-3 months were randomly divided into 5 groups (n=8) as sham (P), partial obstruction (P), P+tadalafil (PT), complete obstruction (C), and C+tadalafil (CT). Animals in the PT and CT groups were administered with tadalafil (10 mg/kg, ig) just before the anesthesia. Twenty-four hours after the obstruction surgery, the animals were sacrificed. In the kidney homogenates, MDA and AOPP levels were examined in addition to SOD and CAT activities. Serum creatinine levels were also measured.Results: Both partial and complete obstruction caused a significant increase in the serum creatinine, tissue MDA and tissue AOPP levels. Although unchanged SOD activity, renal CAT activity decreased significantly in P and C groups. In tadalafil treated animals, serum creatinine, tissue MDA and AOPP levels, or renal SOD activity did not change compared to obstructed groups. However, the renal CAT activity increased in tadalafil-treated groups. A single-dose tadalafil treatment significantly restored renal CAT activity to the range of controls in the PT group.Conclusion: Although tadalafil did not affect renal oxidative stress induced by partial or complete UUO, elevation of CAT activity to control values in the PT group suggests that increasing doses or duration of tadalafil treatment might be protective for kidneys in UUO

Özet

Amaç: Spesifik bir fosfodiesteraz-5 (PDE5) inhibitörü olan tadalafilin iyi bilinen vazoaktif etkilerinin yanı sıra antioksidan etkileri de gösterilmiştir. Bu çalışmada, tek taraflı üreteral obstrüksiyonun böbrekte neden olduğu oksidatif stres artışında tadalafilin olası koruyucu etkisi incelenmiştir.Yöntemler: 2,5-3 aylık Sprague-Dawley erkek sıçanlar 5 gruba ayrılmıştır (n=8); sham (S), parsiyel obstrüksiyon (P), P+Tadalafil (PT), komplet obstrüksiyon (K) ve K+Tadalafil (KT). PT ve KT gruplarına cerrahi işlemden hemen önce, tek doz tadalafil (10 mg/kg, ig) verilmiştir. Denekler, obstrüksiyondan 24 saat sonra sakrifiye edilmiştir. Böbrek homojenatlarında MDA, AOPP düzeyleri ile SOD ve CAT aktiviteleri incelenmiştir. Böbrek fonksiyon göstergesi olarak da serum kreatinin düzeyi ölçülmüştür.Bulgular: Hem parsiyel hem de komplet obstrüksiyon, serum kreatinin değerlerinde, böbrek MDA ve AOPP düzeylerinde istatistiksel önemli artışlara neden olmuştur. SOD aktivitesinde büyük bir değişim olmamakla birlikte, CAT aktivitesi hem P hem de K gruplarında azalmıştır. Obstrüksiyon grupları ile kıyaslandığında, tadalafil tedavisi serum kreatinin, doku MDA, AOPP seviyesi ve SOD aktivitesinde önemli bir değişime neden olmamıştır. Ancak, tadalafil tedavisi alan gruplarda CAT aktivitesi yüksek bulunmuştur. PT grubunda tek doz tadalafil uygulaması, CAT aktivitesinin kontrol değerlerine dönmesini sağlamıştır.Sonuç: Tek taraflı parsiyel ve komplet üreter obstrüksiyonunun neden olduğu renal oksidatif stres artışına tadalafilin önemli bir etkisi görülmemiştir. Ancak PT grubunda CAT aktivitesinin kontrol değerlerine yükselmesi, tadalafil tedavisinin süresi veya dozundaki artışların UUO'da böbrekler için koruyucu olabileceğini düşündürmektedir
