Abstract
Bu çalışmada, opera olmamış meme kanserli hastalarında malondialdehit (MDA) düzeyi ile süperoksit dismutaz (SOD), indirgenmiş glutatyon (GSH) ve glutatyon peroksidaz (GPx) gibi bazı antioksidan aktivitelerin belirlenmesi amaçlandı. SOD, GSH ve GPx aktiviteleri opera olmamış meme kanserli hasta grubu sağlıklı kontrol grubuna göre anlamlı olarak düşük bulundu (p<0.05). Opera olmamış meme kanserli hasta grubu, MDA düzeyleri sağlıklı kontrol grubuna göre anlamlı olarak yüksek bulundu (p<0.05). Sonuç olarak, opera olmamış meme kanserli hastalarda oksidatif stres artışı hücresel hasarı meydana getirebilir. Bunun sonucunda lipid peroksidasyon düzeyi (MDA) artarken, buna karşılık antioksidant aktiviter ise azalmıştır.
In this study, it was aimed to determine malondialdehyde (MDA) level and some antioxidant activities such as superoxide dismutase (SOD), reduced glutathione (GSH) and glutathione peroxidase (GPx) in patients with non-operated breast cancer. SOD, GSH and GPx activities were found to be significantly lower in the unoperated breast cancer patient group compared to the healthy control group (p<0.05). The MDA levels of the unoperated breast cancer patient group were found to be significantly higher than the healthy control group (p<0.05). In conclusion, increased oxidative stress may cause cellular damage in non-operated breast cancer patients. As a result, lipid peroxidation level (MDA) increased, while antioxidant activity decreased.
