ABSTRACT
Background: Although hydro-alcoholic extracts of Anethum graveolens L. had Anticonvulsants effect on PTZ-induced kindling seizure behavior, but on the amygdala kindling in rats induced seizure has not been investigated
Objective: In this study, we evaluated the chronic effects of hydro-alcoholic extracts of Anethum graveolens L. on seizures using electrical amygdala kindling model
Methods: Rats were divided into six groups. They were kindled by stimulating the amygdala by consecutive daily. Then, treated by hydro-alcoholic extracts of Anethum graveolens L. [i.p. 100, 200 and 400 mg/kg] and Afterdischarge Duration [ADD], Stage 4 latency [S4L] and Stage 5 duration [S5D] were recorded
Results: Hydro-alcoholic extracts of Anethum graveolens L. [200 and 400 mg/kg] significantly increased stage 4 latency compare to the control group [P <0.05]. Hydro-alcoholic extracts of Anethum graveolens L. [400 mg/kg] injection stage 5 duration caused by amygdala electrical kindling. Hydro-alcoholic extracts of Anethum graveolens L. [100, 200 and 400 mg/kg] injection significantly reduced ADD induced by amygdala kindling
Conclusion: The data showed that injection of hydro-alcoholic extracts of Anethum graveolens L. has anti-epileptic effect and increases the time required for amygdala kindling and may have anticonvulsant effects
ABSTRACT
Background and Aims: Epilepsy is a central nervous system disorder that appears as sudden convulsions, and transient, repetitive and unpredictable movment, with sensory-motor and autonomic sources. Nowadays, patients with epilepsy use various types of chemical drugs which turn out side effects and cause drug resistance in long-term use. Ease of using herbal plants and their public acceptance have provided them appropriate for pharmacological purposes. Scrophularia striata Boiss., plant grows in areas of Ilam in Iran, has been experimentally used in the treatment of various diseases. In this experiment, the effect of hydroalcoholic extract of this plant was studied on pentylenetetrazol-induced seizures
Methods: 40 male mice [25-30 g] were randomly selected and divided into five groups of 8, including a control group [receiving saline and pentylenetetrazol] and 4 treatment groups [receiving the extract doses of 150, 300, 600, 900 mg/kg]. 30 minutes after interaperitoneal administration of saline and extract, pentylenetetrazol [80 mg/kg] was injected. The mice were immediately transferred to a special cage and convulsive behaviors were recorded by a camera during the 20 minutes. Then, the different phases of seizure were evaluated
Results: Extract injection in dose of 150 mg/kg had no significant effect on onset time of different levels of seizure. But, extract injection in doses of 300 and 600 and 900 mg/kg delayed the onset time of tonic, clonic and tonic-clonic seizures. The extract administration in all treatment doses also reduced duration time of tonic and tonic-clonic seizures and decreased the numbers of imbalances and fallings in different seizure phases. As well, the extract decreased mortality to zero
Conclusion: Our study indicated that the hydro-alcoholic extract of Scrophularia striata Boiss. has an appropriate anticonvulsant effect and it seems that the future studies are necessary to separate its ingredients and understand its mechanism of action
