effects of hydro-alcoholic extract of anethum graveolens seed on pentylenetetrazol-induced seizure in adult male mice

introduction: regarding chronic nature of epilepsy and its side effects and to access the effective treatment procedures, herbal medicine has received remarkable interest. the aim of this study was to determine the anticonvulsant effects of hydro-alcoholic extract of anethum graveolens seed on pentylenetetrazol (ptz) -induced seizure in male mice. methods: fifty-six albino male mice were divided randomly into seven groups including the negative control (saline), positive control (phenobarbital) and treatment groups using different doses of hydro-alcoholic extract of anethum graveolens seed (50, 100, 300, 500 and 1000 mg/ kg). to provoke convulsion, ptz was injected to all groups and initiation time of myoclonic and tonic-clonic seizures as well as surveillance after 24 h were measured. results: the results indicated that hydro-alcoholic extract of anethum graveolens seed (ags) delayed the initiation time of myoclonic and tonic-clonic seizures in comparison with saline group. the latency was considerable for myoclonic and tonic-clonic seizures at all above mentioned doses of ags extract except for the lowest one. moreover, the protective effect of ags extract against mortality was statistically significant at all doses except for 50 mg/kg. discussion: as the hydro-alcoholic extract of ags showed an appropriate response in experimental model of convulsion, it might be considered as an adjuvant therapy with other traditional antiepileptic medications.
