Abstract

Objective: The radioprotective and antioxidant effect of pycnogenol against gamma radiation-induced nephrotoxicity was investigated at single cell level, tissue level and biochemical parameters in adult male Wistar Albino rats. Material and Methods: The study was included control group (n=10), antioxidant groups (P37.5, P75, P150, P300, n= 10), only radiation group (y-ışını, n=10) and antioxidant + radiation groups (P37.5+y-ışını, P75+y-ışını, P150+y-ışını, P300+y-ışını, n= 10) on 100 rats. Pycnogenol was dissolved in 5 % DMSO. Radiation was applied single fraction with Cobalt-60 teletherapy device. Control and radiation groups were received 5% DMSO. Antioxidant and antioxidant + radiation groups were received pycnogenol at 24, 48 and 72 hours before the irradiation. Twenty-four hours after the administra- tion, the rats were sacrificed with general anesthesia and their kidneys were removed. DNA damage, histopathological evaluation, CAT, SOD activities and MDA levels were evaluated in renal tissue. Results: We were evaluated increased levels of MDA, decreased SOD and CAT activities in the radiation group; however, MDA level was decreased and increased SOD and CAT activities in the antioxidant + radiation group. Comet parameters were increased in the other groups compared to the control group and these parameters were decreased in the antioxidant + radiation groups compared to the radiation group (p <0.001). Histopatho- logically, impaired histopathology was observed in the other groups compared to the control group and improved histopathology was observed in the antioxidant + radiation groups compared to the radiation group. Conclusion: Pycnogenol is which has been shown to have antioxidant effects, as a protective against kidney damage due to ionized radiation, may be suggested based on the data of our study. However, preclinical and clinical studies are also needed to better understand the mechanism of action and molecular basis and to clarify dose, toxicity and tolerability issues.

Özet

Amaç: Gama radyasyonun indüklediği nefrotoksiteye karşı pycnogenolün radyasyon koruyucu ve antioksidan etkisi tek hücre düzeyinde, doku düze- yinde ve biyokimyasal parametreler kullanarak Wistar Albino cinsi erişkin erkek sıçanda araştırıldı. Gereç ve Yöntem: Çalışma, kontrol grubu (n=10), antioksidan gruplar (P37.5, P75, P150, P300, n= 10), sadece radyasyon grubu (y-ışını, n=10) ve antiok- sidan + radyasyon gruplar (P37.5+y-ışını, P75+y-ışını, P150+y-ışını, P300+y-ışını, n= 10) olmak üzere 100 sıçanda yapıldı. Pycnogenol %5’lik DMSO’da çözdürüldü. Radyasyon Cobalt-60 teleterapi cihazıyla tek fraksiyon uygulandı. Kontrol ve radyasyon grubuna %5 DMSO, antioksidan ve antioksidan + radyasyon gruplar ışınlamadan önce 24, 48 ve 72. saatlerde pycnogenol verildi. Uygulamalardan yirmidört saat sonra, genel anesteziyle sıçanlar sakrifiye edilerek böbrekleri alındı. Böbrek dokusunda, DNA hasarı, histo-patolojik değerlendirme, CAT, SOD aktiviteleri ve MDA düzeyleri değer- lendirildi. Bulgular: Radyasyon grubunda MDA düzeyinde artma, SOD ve CAT aktivitelerinde azalma; buna karşılık antioksidan + radyasyon grubunda MDA düzeyinde azalma, SOD ve CAT aktivitelerinde artma tespit edildi. Kontrole göre diğer gruplarda comet parametreleri artmış, bu parametreler anti- oksidan + radyasyon gruplarda radyasyon grubuna göre azalmıştı (p<0.001). Histopatolojik olarak, kontrol grubuna göre diğer gruplarda bozulmuş histo-patoloji, antioksidan + radyasyon gruplarda, radyasyon grubuna göre düzelmiş histo-patoloji gözlendi. Sonuç: Antioksidan etkileri gösterilen pycnogenolün iyonize radyasyona bağlı böbrek hasarına karşı koruyucu olarak kullanılması, çalışmamızın verilerinden hareketle önerilebilir. Ancak, etki mekanizmasının ve moleküler temelinin daha iyi anlaşılması, doz, toksisite ve tolerabilite konularının daha da açıklığa kavuşması için, preklinik ve klinik çalışmalara da gerek vardır.
