title: Lutein protects against ischemia/reperfusion injury in rat kidneys.
abstract: Ischemia‑reperfusion (I/R) injury has a major impact on renal dysfunction during transplantation. The present study investigated the role of lutein against I/R injury‑induced oxidative stress in rat kidneys. Biochemical analysis and oxidative stress parameters demonstrated that lutein protected the rat kidney significantly from I/R injury. Pretreatment with lutein significantly increased the total antioxidant capacity with a concomitant decline in the total oxidant status. Rats with I/R injury showed a significant increase in oxidative stress. The results revealed significant increases in the levels of lipid peroxidation and protein carbonyl content with concomitant decreases in enzymic and non‑enzymic antioxidants. The activity of these enzymes was reversed and demonstrated a significant increase following lutein pre‑treatment compared with the rats subjected to I/R injury alone. Furthermore, lutein protected the renal tissue from I/R injury by maintaining normal kidney architecture and led to a reduction in the levels of the renal markers urea and creatinine in the serum. These results demonstrated clear evidence that lutein offered a significant protective effect against I/R injury by enhancing antioxidant defense mechanisms.
