Abstract

Gentamicin, an aminoglycoside drug, used for the treatment of Gram-negative bacterial infections. Despite its potency against bacterial infections, its clinical use is limited owing to nephrotoxicity effect. However, the study investigated the nephroprotective effect of fatty acids from ethanolic extract of Moringa oleifera seeds (EEMOS) against gentamicin-induced kidney injury in rats. Forty-five male Wistar rats, 100–160 g, were divided into 5 groups as follows: Group 1 (control), 5 rats, received 0.2 ml/100 g/day of propylene glycol orally for 28 days. Group 2, 10 rats, received 100 mg/kg/day (i.p) of gentamicin (GENT) for 8 days. Group 3–5, 10 rats each, treated with EEMOS orally for 28 days at graded doses of 100, 200 and 400 mg/kg respectively after GENT treatment. Twenty four after treatment, five rats from each group were sacrificed. The remaining 5 rats were sacrificed after 2 weeks recovery period from the drugs. The result showed that GENT elicited polyuria, elevated plasma creatinine, urea, and lower plasma electrolytes and creatinine clearance levels. Measurements of 24 h urinary output demonstrated marked decrease in creatinine and potassium levels in the GENT-treated group, whereas sodium level remain unchanged. Also, GENT caused significant decrease in superoxide dismutase and an increase in malondialdehyde levels in the kidney of the rats. Histopathological examination revealed evidence of necrosis of the kidney. Treatment with EEMOS significantly ameliorated the alterations caused by GENT in the plasma, urine and kidney homogenate of the rats. Hence, the mono- and poly-unsaturated fatty acids present in EEMOS were responsible for its renoprotective ability.
