Fish Liver Oil and Propolis Act as Neuroprotective Agents

Efficacy of Fish Liver Oil and Propolis as Neuroprotective Agents in Pilocarpine Epileptic Rats Treated with Valproate
Pathophysiology, Volume 18, Issue 4, September 2011, Pages 287–294

Objective: To evaluate the action of fish liver oil and propolis in pilocarpine epileptic rats treated with the anticonvulsant drug valproate.

Methods: Seven groups of rats were treated daily for six months: control; fish liver oil (0.4 ml/kg b.w); propolis (50 mg/kg b.w); pilocarpine-treated rats (epileptic control); epileptic rats treated with valproate (400 mg/kg b.w); groups 6 and 7, epileptic rats treated with valproate plus fish liver oil or propolis.

Results: Pilocarpine administration caused a significant increase in hippocampal dopamine and serotonin levels accompanied with a significant decrease in their levels in serum. Lipid peroxidation level and LDH activity in hippocampus were significantly increased after pilocarpine treatment whereas Na+/K+-ATPase activity and total antioxidant capacity were significantly decreased compared to the controls. Animals treated with the combined treatments showed a significant improvement in tested parameters towards the normal values of the control. 

Conclusion
: Fish liver oil and propolis when given in combination with valproate, neuroprotected against the neurophysiological disorders induced by pilocarpine epilepsy in rats.
