Abstract: 

Consumption of fruits and the other dietary antioxidants are considered beneficial due to the protection they afford in the pathogenesis associated with oxidative stress. The aim of this study was to evaluate the antioxidative effects of selected fruit extracts (Plums, Apples, Grapes and Cranberries) on human lung fibroblasts (CCD-25LU) exposed to tert-butyl hydroperoxide (tBHP) oxidative stress. Lactate Dehydrogenase (LDH) was used to assess cytotoxicity (cell integrity) and antioxidant enzymes catalase (CAT), glutathione-s-transferase (GST), glutathione peroxidases (GPx) and concentrations of reduced glutathione (GSH) were determined. Results showed that LDH release by cells pretreated with fruits extracts were significantly (p
