Abstract:
Background: In Africa, Aluminium phosphide is commonly used for storage and transportation
of food grains. Unfortunately, the chemical build up in the food we eat is poisonous without a
specific antidote. We speculate that the antioxidant effects of vitamins C and D could mitigate
the long list of side effects. Aim of the Work: To determine the possible protective effect of
vitamins C and D against phosphine-induced kidney damage in Wistar rats Materials and
Method: This is an experimental laboratory-based study. Twenty Wistar rats were assigned
randomly into five groups (n=4). Group, I served as the normal control while Groups II-V were
exposed to 2.5 mg/kg phosphine tablet. Group II was the positive control without treatment
while Groups III-V were treated with vitamin C (100mg/kg/bw), vitamin D (10mg/kg/bw).
Group V was co-administered with vitamins C and D. All treatments lasted for 30 days. Animals
were euthanized and blood was collected via cardiac puncture for renal function parameter
while excised kidney was processed histologically by the paraffin wax method. Result: There
was a significant increase in the urea and creatinine levels in phosphine-induced animals,
indicating the kidney was injured. Creatinine is a more reliable marker for assessing kidney
function than urea. Moreover, a number of interstitial foci of haemorrhage and inflammatory
cells observed on the kidney confirmed the renal toxicity of phosphine. However, the co-
administration of vitamins C and D produced a dose-related improvements in the kidney
parenchyma. Conclusion: Aluminium phosphide is toxic to the kidney parenchyma. However,
co-administration of vitamins C and D ameliorates phosphine-induced kidney damage.
