Abstract | Background: Acute renal failure induced by ischemia / reperfusion (I/R) causes excretory functional disorders of nephrons. The purpose of this study is to evaluate the intake of oral rosemary extract (gavage) on hemodynamic changes and tissue damages caused by I/R. Materials and Methods: This study was conducted on 40 Sprague-Dawley male rats, composed of 4 groups (n=10) including control, sham, I/R+normal saline (I/R+NS) posttreatment and I/R+rosemary (I/R+RO) post-treatment. They were fed with 10 ml/kg of 8% aqueous extract or vehicle as gavages during the first 48 hours after I/R. To induce I/R, both renal artery and vein were blocked for 30 minutes followed by a reperfusion within 48 hours. Then urine and plasma samples were collected and histological study was also conducted after removal of both kidneys. Data were analyzed by SPSS-11.5 software. The one-way analysis of variance (ANOVA) and Duncan test were used for intergroup comparison and p≤ 0.05 was used as the significant level. The Kruskal–Wallis multiple comparison test was also used for doing histological analysis Results: Comparison of renal function between two groups of (I/R+RO) and (I/R+NS), showed a significant reduction in plasma creatinine (p=0.05), the blood urea nitrogen (p=0.05), absolute excretion of sodium (p=0.001) and an increase in absolute potassium excretion (p=0.01). Results of the histological study also indicated a significant decrease in the vascular congestion, Bowman’s capsule space and oxidative stress in the group (I/R+RO) in comparison with (I/R+NS). Conclusion: Treatment with rosemary may be effective in the reduction of the functional and histological effects of I/R. |
