Özet

Bu çalışmada, tavşanlarda dietilnitrozaminin (DEN) oluşturduğu erken oksidatif, inflamatuvar ve apoptotik değişikliklere karşı Ginkgo biloba ekstresi (GB) değerlendirildi. Otuz iki tavşan kontrol, DEN, DEN+GB ve GB gruplarına ayrıldı (her grupta n = 8). DEN tek doz 100 mg/kg intraperitoneal, GB ise 60 gün boyunca günde bir oral kapsül olarak uygulandı. Plazma tümör nekroz faktörü alfa (TNF-α) ve 8-hidroksi-2′-deoksiguanozin (8-OHdG) düzeyleri 7., 30. ve 60. günlerde; karaciğer DNA parçalanması TUNEL yöntemiyle değerlendirildi. Yedinci günde TNF-α ve 8-OHdG, DEN grubunda kontrol ve GB gruplarından yüksekti (p < 0,05); DEN+GB grubu ara değerler gösterdi. Otuzuncu günde TNF-α DEN grubunda diğer gruplardan yüksek kalırken (p < 0,05), 60. günde iki belirteç için de fark bulunmadı. DEN grubunda az sayıda TUNEL-pozitif hücre gözlendi; diğer gruplarda bu hücreler yoktu veya seyrekti. GB erken oksidatif ve inflamatuvar yanıtın sınırlanmasıyla ilişkiliydi; ancak tümör oluşumunun önlendiği gösterilmedi.

Abstract

This study evaluated whether Ginkgo biloba extract (GB) attenuates early oxidative, inflammatory, and apoptotic changes induced by diethylnitrosamine (DEN) in rabbits. Thirty-two rabbits were allocated to control, DEN, DEN+GB, and GB groups (n = 8 each). DEN was administered once intraperitoneally at 100 mg/kg, and GB was given as one oral capsule daily for 60 days. Plasma tumor necrosis factor alpha (TNF-α) and 8-hydroxy-2′-deoxyguanosine (8-OHdG) were measured on days 7, 30, and 60; hepatic DNA fragmentation was assessed by TUNEL. On day 7, TNF-α and 8-OHdG were higher in the DEN group than in the control and GB groups (p < 0.05), while DEN+GB showed intermediate values. On day 30, TNF-α remained higher in the DEN group than in all other groups (p < 0.05). Neither marker differed among groups on day 60. Few TUNEL-positive cells occurred in the DEN group and were absent or sparse elsewhere. GB was associated with attenuation of early DEN-related oxidative and inflammatory responses, but prevention of tumor formation was not demonstrated.
