Antioxidant effect of vitamin E and 5-aminosalicylic acid on acrylamide induced kidney injury in rats

Nisreen A. Rajeh, Najlaa M. Al-Dhaheri


Objectives: To explore renal toxicity caused by sub-acute exposure of acrylamide and to study the protective effect of 5-Aminosalicylic acid (5-ASA) and Vitamin E (vit-E)on Acrylamide (ACR) induced renal toxicity.


Methods: This study was conducted at King Fahad Medical Research Centre, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia, between August and November 2015. A total of 49 adult Wistar rats (250 ± 20g) aged 60 days were kept in a controlled environment and used in the present study. The rats were divided into 7 groups (control, ACR alone, ACR+5-ASA, ACR+vit-E, ACR+ASA+vit-E, vit-E alone, and ASA alone). After 5 days of ACR oral gavage treatment, the rats were observed for 24 hours then killed. Histopathology for the kidney and lactate dehydrogenase assay were carried out. 


Results: Acrylamide produced significant pathological changes in the kidney with acute tubular necrosis in the distal tubules that could be reversed by concomitant injection of rat with 5-ASA. Together with vitamin E, 5-ASA, showed maximum renal protection. No statistically significant difference was observed in either body weights or lactate dehydrogenase activity of ACR treated rats. 


Conclusion: Acrylamide exposure leads to adverse clinical pathologies of renal tubules, which were reversed by a concomitant treatment with 5-ASA and vitamin-E
