Abstract:
Introduction: To study the protective effect of extra virgin olive oil (EVOO) on histopathological changes induced by arsenic in the kidneys of albino rats. Randomized control trial. November 1, 2017–November 30, 2017 at National Institute of Health. Material and Methods: Forty‑five male adult albino rats were placed in three cages having 15 rats each. Distilled water was given to the rats of control Group I for 30 days. The dose of sodium arsenite given to rats was 40 mg per kg per day dissolved in drinking water for 30 days. Olive oil of 0.2 ml per day was only given to Group III rats for 30 days along with sodium arsenite. In dissection was done after 30 days and their kidneys were approached and dissected out for histological changes. Results: EVOO has ameliorated the microscopic quantitative and qualitative histological changes induced by arsenic on both kidneys of albino rats. Olive oil had significantly prevented the increase in the diameter of the proximal convoluted tubule (PCT). Discussion and Conclusion: The present study demonstrates that EVOO prevents the quantitative and qualitative histological changes caused by arsenic on kidneys which include the diameter of PCT and distal convoluted tubule, the diameter of glomeruli, width of bowman’s space, and loss of brush border.
