Abstract:

Background: (banana) plant extract has been shown to possess antioxidant activity in previous studies. Neuronal injury resulting from oxidative stress is an important factor involved in pathogenesis of epilepsy.

Objective: The present study aimed to evaluate the anticonvulsant activity ofstem extract (MSSE) in acute and chronic experimental models in mice and its effects on various markers of oxidative stress in the brain of pentylenetetrazole (PTZ)-kindled animals.

Material and Methods: Maximal electroshock seizures (MES) and PTZ-induced convulsion models were used for acute studies. For the chronic study, the effect of MSSE on the development of kindling was studied. For the evaluation of the effects of MSSE on oxidative stress in brain, malondialdehyde (MDA) and reduced glutathione (GSH) levels were estimated in the brains of the kindled animals.

Results: MSSE significantly increased the latency to onset of myoclonic jerks and the duration of clonic convulsions following PTZ administration. The MSSE pretreated group showed significantly reduced mean seizure score on PTZ-induced kindling. There was a significant increase in the brain MDA levels and decrease in GSH levels in response to PTZ-induced kindling. On MSSE pretreatment, there was a significant decrease in the MDA levels in the brains, though the increase in the GSH levels was not significant.

Conclusion: The results from this study suggest the presence of significant anticonvulsant activity in MSSE, in both acute and chronic PTZ-induced seizure models, which could be due to its antioxidant activity, as is reflected by the change in oxidative stress markers in brain.

SUMMARY: Evaluation of the anticonvulsant activity ofand its effects on various markers of oxidative stress in the brain has not been done previously to the best of our knowledgestem extract (MSSE) significantly increased the latency to onset of myoclonic jerks and the duration of clonic convulsions in the experimental modelsThe MSSE pretreated group showed significantly reduced mean seizure score on pentylenetetrazole (PTZ)-induced kindlingThere was significant increase in the brain malondialdehyde (MDA) levels and decrease in glutathione (GSH) levels in response to PTZ-induced kindlingOn MSSE pretreatment, there was a significant decrease in the MDA levels in the brain, though the increase in the GSH levels was not significant.MSSE:stem extract, PTZ: Pentylenetetrazole, MES: Maximal electroshock seizures, MDA: Malondialdehyde, GSH: Glutathione, SOD: Superoxide dismutase, THLE: Tonic hindlimb extension.
