Background: The present study was designed to evaluate the nephroprotective effect of the leaves of Aloe barbadensis against toxicity induced by diclofenac sodium in albino rabbits.
Subjects and Method: Thirty-six healthy albino rabbits were randomly divided into six groups each with six animals. Group 1 served as the untreated control, group 2 was treated only with diclofenac sodium, group 3 with the nephroprotective drug silymarin and groups 4, 5, and 6 were treated with different doses of Aloe barbadensis, ie 200 mg/kg, 400 mg/kg and 600 mg/kg, respectively after being treated with diclofenac sodium. Blood samples were collected after every five days up to fifteen days. Haematological and histopathological parameters were determined by using diagnostic kits.
Results: Results of haematological studies showed that use of the powder of Aloe barbadensis normalized the level of different factors eg, white blood cells (WBCs), red blood cells (RBCs), platelet count, packed cell volume (PCV), mean cell volume (MCV) and haemoglobin (Hb) values. Histopathological studies showed that Aloe barbadensis ameliorated pyknotic nuclei in the renal epithelial cells and reduced oxidative stress by increasing the level of catalase and decreasing malondialdehyde (MDA) level.
Conclusion: These results have shown that Aloe barbadensis can normalize oxidative stress and can be used as an effective nephroprotective agent against drug-induced nephrotoxicity.
