Abstract

Aegle marmelos is well documented for antihyperglycemic effect and PPAR-γ activation has been suggested to be the molecular mechanism of its action. Also, the plant has been used in Ayurveda as a brain tonic and has been postulated to have antidepressant activities. The present study was designed to investigate the anticonvulsant effects of A. marmelos leaf extract (AME) in pentylenetetrazole and maximal electroshock induced convulsions; involvement of PPAR-γ, nitric oxide pathway and effect of chronic AME treatment on post-ictal depression. AME was administered at doses of 50, 100 and 200 mg kg-1 in PTZ and MES model. Severity of convulsions was noted in both the models. Pretreatment with bisphenol A diglycidyl ether (BADGE) was used to study the involvement of PPAR-γ and l-arginine and N-nitro-l-arginine methyl ester hydrochloride (l-NAME) to study the involvement of nitric oxide (NO). Chronic treatment with AME interspersed with sub maximal doses of PTZ (50 mg kg-1) on every fifth day up to 15 days was given to study post-ictal depression using forced swimming and actophotometer. AME showed significant increase in the onset time and decrease in the duration of convulsions in PTZ and MES models dose dependently. In MES a dose of 100 mg kg-1 had effect comparable to phenytoin. Pretreatment with BADGE and l-arginine reversed the protective effect while l-NAME did not alter the protective effect, thereby indicating possible involvement of PPAR-γ and inhibition of NO. Chronic AME treatment ameliorated the post-seizure depression significantly as evidenced by increase in the locomotor activity and decrease in the immobility time.
