Background: Acute kidney injury is a serious medical condition that usually results in sudden loss of renal function and high mortality
rate in the world. The efficacy and the mechanisms of ethanol leaf extract of Moringa oleifera in promoting recovery from glycerol induced
Acute Kidney Injury (AKI) in rats was investigated in this study.
Methods: Thirty-five adult male Wistar rats were randomly sorted into five groups of seven animals each. Control received distilled
water alone, Untreated group received single glycerol (4 ml/kg) intramuscularly, two groups were pretreated orally with 50 and 100 mg/kg of
Moringa oleifera respectively for seven days and then injected with a single glycerol (4ml/kg) subcutaneously on day eight. Another
group received oral administration of Moringa oleifera alone at 100 mg/kg for seven days. The animals were later sacrificed through cervical
dislocation twenty-four hours after glycerol was administered.
Results: Serum and renal homogenate analysis revealed that glycerol induced significant increases in creatinine kinase renal band, nitric
oxide, malondialdehyde, protein carbonyl, myeloperoxidase, advanced oxidative protein products alongside a decrease in superoxide
dismutase, reduced glutathione, glutathione peroxidase and an increase in the expression of Kidney Injury Molecule-1 (KIM-1) and Nuclear
Factor Kappa Beta (NF-kB) using immunohistochemistry. Treatment with Moringa oleifera at both doses used brought on a reversal of these.
Conclusion: These results support the hypothesis that oral administration of methanol stem extract of Moringa oleifera is effective in abrogating
oxidative stress, attenuating inflammation, and enhancing nephrogenic repair after glycerol-induced AKI.
