The liver is an essential organ involved in anabolic and catabolic processes in the body. Substance like paraquat is injurious to the liver by way of oxidative damage. Vitamin E and C are known antioxidant used to tackle oxidative stress. The aim of this study was focused at evaluating the antidotal benefit of vitamin E and C in the treatment of paraquat intoxication in rat. Exactly 200 rats were obtained and grouped into four main groups (A, B, C and D) with each group having 50 rats. Except “A” group which was the control, all groups were treated with paraquat in doses of 0.02g, 0.04g and 0.06g respectively every 2 weeks for 3 months. All groups were subdivided into two groups designated as “0” and “VEC” amounting to a total of 8 subgroups. All subgroups with “VEC” designation were treated with 500mg of vitamin E and 2000mg/dl of vitamin C weekly for 3 months. Blood samples collected after treatment duration were via cardiac puncture and blood was assayed for liver enzyme activities. Results revealed that there was a significant increase (p-value<0.05) in liver enzyme activities among the groups (A0, B0, C0 and D0). Also, there was a significant drop in liver enzyme activities after vitamin E and C supplementation.
