Abstract
The role of oxidative stress in the pathogenesis of various diseases has
been established. Maintaining the steady balance between reactive oxygen species
and natural antioxidants is a crucial factor, and could probably serve as a major
mechanism in preventing damage by oxidative stress induced by toxic substances. A
comparative study and correlation analysis of malondialdehyde (MDA), serum
vitamins (A, E and C) and the redox active metals (Cu, Fe and Zn) in CCl4 induced
oxidative stress in albino rats with various doses of CCl4 were determined. The serum
levels of oxidative stress markers were compared between the normal and test groups.
The result showed a significant increase in the serum vitamins A and E in the CCl4
induced oxidative stress rats compared to control rats (P<0.05). However, the serum
level of vitamin C was not statistically different compared to control rats (P>0.05).
MDA correlated strongly and positively with vitamin C (r=0.94), Vitamin A(r=0.87),
Vitamin E and Fe(r= 0.90 and 0.87 respectively) while the serum MDA showed a
weak positive relationships with Zn(r=0.02) and Cu(r=0.47).Thus, the increased
serum levels of some antioxidant vitamins and the redox metals in the experimental
rats as observed in this study could be a compensatory regulation in response to
induced oxidative stress by CCl4.The evidence from this study lends credence to the
ability of endogenous antioxidants to counter the effects of free radicals generated by
hepatotoxic substances and maintain the steady-state of prooxidant-antioxidant
balance in the system.
