ABSTRACT
PTZ-induced kindling causes memory disruption in rats is a consequence of changes within the
central nervous system that are secondary to impaired oxidative stress. Treatment with antioxidants are
reported to produce beneficial effects in animal models. Ellagic acid reported to exhibit antioxidant effect.
However, no report is available on the influence of ellagic acid on PTZ-induced kindling causes memory
impairment. Therefore, we tested its influence against cognitive dysfunction in PTZ-induced epileptic rats
using passive avoidance test. Lipid peroxidation and glutathione levels as parameter of oxidative stress
were assessed in the hippocampus. After induction of epilepsy PTZ treated rats showed a severe deficit in
learning and memory associated with increased lipid peroxidation, decreased glutathione activity. In
contrast, treatment with ellagic acid (7.5-30 mg/kg, p.o.) improved cognitive performance, and lowered
oxidative stress in PTZ treated rats. In conclusion, the present study demonstrates that treatment with
ellagic acid prevents the changes in oxidative stress and consequently memory impairment in PTZ treated
rats.
