Background: Renal ischemia-reperfusion is known as the underlying pathophysiology of a variety of severe clinical disorders, such as acute renal failure. The use of antioxidants is one of the most important treatment strategies to reduce the ischemia-reperfusion induced injury due to the importance of reactive oxygen species and oxidative stress during ischemia reperfusion. Salvia spices, especially Salvia macrosiphon Boiss, are rich in antioxidant compounds. The present study aimed to investigate the protective effects of these substances on renal ischemia reperfusion.
Materials and Methods: In this study, 42 Wistar rats were divided into six groups of seven animals per group. The groups included a sham, a control, and four treatments. One of the treatment groups was treated with luteolin, and the other three groups were treated with different concentrations (50, 100, 150 mg/kg) of Salvia macrosiphon Boiss methanolic extract for 20 days before ischemia. After 24 hours following ischemia, blood samples were taken from the rats, and their serum creatinine and urea levels were evaluated.
 Results: Salvia macrosiphon Boiss extract (at the dose of 100 mg/kg) significantly reduced urea and creatinine levels (P<0.001). Moreover, Luteolin decreased both ceratinine (P<0.01) and urea (P<0.05) levels.
Conclusion: This study confirmed the positive and significant effect of Salvia macrosiphon Boiss extract and Luteolin on the studied factors. The observed effect could be in part due to the potential antioxidant properties of flavonoids and methanol extract of Salvia macrosiphon Boiss.
