Abstract

This study was designed to evaluate the possible antioxidant and antihepatocarcinogenic effects of soybean (SB) and Nigella sativa (NS) in rats administered nitrosamine precursors dibutylamine and sodium nitrate in the drinking water. Rats were randomly divided into four groups, each containing 48 animals. Group I (control), group II (dibutylamine (DBA) + NaNO3), group III (DBA/NaNO3 + SB treated) and group IV (DBA/NaNO3 + NS treated). Markers of oxidative stress [reduced glutathione (GSH) and nitric oxide (NO)] and the levels of HER-2/neu, bcl-2 and p53 proteins were investigated in rats liver after 2, 4, 6, 8, 10 and 12 months. The data revealed an improvement in the status of oxidative stress represented as the compensation of GSH levels after 2 and 4 months and reduction of NO levels after 2 months; a significant improvement in the levels of HER-2/neu protein after 6 and 4 months in rats fed SB and NS, respectively. Although, the level of p53 protein was ameliorated compared with the treated with nitrosamine precursor rats, it was maintained in a lower levels compared with the time matched points of the normal controls until 12 months Both SB and NS improved the levels of bcl-2 after 2 months in both groups. The data suggested that oral feeding of the diet containing SB and NS antagonized the oxidative stress effects induced by DBA/NaNO3.

Özet

Bu çalışmada soya fasulyesi (SB) ve nigella sativa (NS)’nın içme suyu ile nitrozamin öncülleri dibutilamin ve sodyum nitrat verilmiş sıçanlardaki antioksidan ve anti hepatokarsinojenik etkilerinin araştırılması hedeflenmiştir. Bu amaçla sıçanlar, her biri 48 hayvandan oluşan gelişigüzel dört gruba ayrılmıştır: Grup I (kontrol), grup II (DBA/NaNO3+ NS verilmiş) grup III (DBA/NaNO3+ SB verilmiş). Sıçan karaciğerinde 2, 4, 6, 8, 10 ve 12 ay sonra oksidatif stres belirteçleri indirgenmiş glutatyon (GSH) ve nitrik oksit (NO) ile HER-2/nem, bcl-2 ve p53 proteinlerinin düzeyleri incelenmiştir. Elde edilen sonuçlar, SB verilen sıçanların oksidatif durumlarında, 2 ve 4 ay sonra GSH düzeyinde düzelme ve 2 ay sonra NO düzeyindeki düşmeyle belirlenen iyileşme olduğunu göstermiştir. HER-2/neu proteininde de anlamlı değişiklik görülmüştür. Ayrıca, p53 protein düzeyi nitrozamin öncülü verilmiş sıçanlarda artmakla birlikte normal kontrollere oranla 12 ay süreyle düşük kalmıştır. Bulgular besinle alınan SB ve NS, DBA/NaNO3 ile oluşturulan oksidatif stresin etkilerini bertaraf ettiğini göstermektedir.
