Abstract:
Background and Objective: Wheras renal ischemic-reperfusion injury increases lipid peroxidation level in the liver tissues, it decreases the antioxidant activity and antioxidant enzymes. Olive leaves are considered as significant sources of bioactive phenolic compounds with superior antioxidant capacity, anti-inflammatory and radical scavenging.
Materials and Methods: In this study ۵۰ male rats were allocated randomly to ۵ groups: ۱) control, ۲) ۱h I/R, ۳) ۱h I/R-OLE (Olive Leaf Extract), ۴) ۲۴h I/R and ۵)۲۴hI/R-OLE. The animals received ۱۰۰ mg/kg olive leaf extract in ۰.۵ ml drinking water using gavage for ۲۸ days in ۳and ۵ groups before induction of ischemia (۱hour). Other animals received ۰.۵ ml normal saline by gavages. At the end of the reperfusion period (۱and ۲۴ hours respectively), the serum level of urea, creatinine and liver enzymes as well as antioxidant enzymes including MDA, SOD and GPX were determined in liver tissue.
Results: MDA level in OLE- treated groups decreased significantly compared to ischemic-reperfusion groups (p<۰.۰۵). In the meantime, it was detected that activity level of SOD and GPX in liver tissue of ischemic groups was significantly lower in comparison to OLE treated groups (p<۰.۰۵).
Conclusion: This study enlightened that OLE is a protective agent against renal ischemic-reperfusion injury in liver tissue.
