Abstract

Objective: Lead exposure or lead poisoning is known to cause a large spectrum of physiological, biochemical, and behavioural disorders in animals. This study was aimed at assessing the effect of vitamin C on the erythrocyte superoxide dismutase, glutathione peroxidase and the glutathione reductase activities in intoxicated- lead rat offsprings. Methods: This study was performed on the pups from female Wistar albino rats. The rats were divided into 4 groups and the treatments were administered through drinking water. Group1 (control group) consumed distilled water. Group 2 (lead group) consumed a solution of lead acetate (300mg/L). Group3 (lead + vitamin C) consumed a solution of lead (300mg/L) which was supplemented with vitamin C (2g/L). Group4 (vitamin group) consumed a solution of vitamin C (2g/L). The enzyme activities were determined in all the 4 groups. Results: The administration of lead showed a decrease in the enzyme activities. The superoxide dismutase activity was increased after the administration of lead in combination with vitamin C. The lead treated rats showed significantly lower body weights at birth and at weaning. The vitamin C treatment showed a significant increase in the body weight. The haemoglobin levels were significantly decreased in the lead-treated rats. The addition of vitamin C to the lead treatment and vitamin C alone could elevate the haemoglobin levels significantly. Conclusion: The results of this study showed that lead alterates the erythrocyte antioxidant enzyme activities. There was an increase in the superoxide dismutase activity following the treatment with vitamin C. This study suggests that the treatment with vitamin C during lactation has a therapeutic effect in the treatment of lead intoxication. The administration of vitamin C prevents haemoglobin reduction in the erythrocytes.
