Sargassum ilicifolium (SI) is a tropical and subtropical marine macroalgae (brown algae) found in coastal area of India. Thais study investigated the anticonvulsant activity of SI in maximal electroshock (MES) induced convulsion and pentylenetetrazole (PTZ) induced convulsion in mice. The result of present study indicated that chloroform extract (600 mg/kg) and ethanol extract (400 mg/kg and 600 mg/kg) of SI significantly decreased the duration of tonic hind limb extension in MES model, as well as it significantly increased the latency to onset of convulsions in PTZ model. These results were comparatively similar with the effect of phenytoin (25 mg/kg) and phenobarbitone (20 mg/kg). This activity may be due to the presence of alkaloids, terpenoids, flavonoids, steroids and saponin in chloroform and ethanol extract of Sargassum ilicifolium. However, further research will be necessary to investigate the exact mechanism underlying this anticonvulsant activity

To evaluate the anticonvulsant activity of the aerial parts of Verbena officinalis used traditionally by local Iranians for the treatment of convulsion. The anticonvulsant activity of the extract was assessed in pentylenetetrazole (PTZ) and maximal electroshock (MES) induced seizures in mice. Diazepam was used as reference drug. In addition, for investigating the mechanism of V officinalis in PTZ model, flumazenil and naloxone were injected before V officinalis. The extract showed no toxicity and significantly increased the period taken before the onset and decreased the duration of the seizures induced by PTZ. In the MES test, V officinalis displayed significant reduction in hind limb tonic extension duration in a dose-dependent manner. The results propose that V officinalis ethanolic extract has anticonvulsant activity against seizure. It seems that these effects may be related to potentiating of GABAergic system. Moreover, this study supports the use of this plant by local Iranians in order to treat convulsion.

Background: To evaluate the anti-convulsant activity of ethanolic extract of Moringa oleifera (Drum stick leaves) in seizure induced albino mice and to compare it with standard drug Sodium valproate.Methods: Swiss albino mice of either sex weighing around 25-30g were randomly selected and divided into four groups of six mice each. Group 1: control- treated with gum acacia. Group 2: Standard - Valproic acid 40mg/kg body weight. Group 3: T1- ethanolic extract of Moringa oleifera (150mg/kg). Group 4: T2 - ethanolic extract of Moringa oleifera (300mg/kg). All drugs were administered orally one hour prior to induction of seizure. The anticonvulsant activity was screened using maximal electroshock seizure (MES) model and pentylenetetrazole (PTZ) model.Results: Results were analysed by ANOVA followed by Bonferroni’s post hoc test. Abolition of Tonic hind limb extension was taken as the protective end point against MES induced seizures and prolongation of seizure latency in PTZ model.At both the doses the ethanolic extract of Moringa oleifera significantly (p value <0.05) reduced the duration of hind limb extension in MES test and also significantly (p value <0.05) delayed the onset of clonic seizures in PTZ induced convulsion when compared with control group.Conclusions: On comparing the percentage protection offered by Moringa oleifera leaves against both MES and PTZ model, it possesses significant anticonvulsant activity at both doses, with more efficacy at 300mg/kg BW indicating that the test drug can prove a very promising drug for treatment of epilepsy. Further studies are required for isolation and identification of the active constituent.

Abstract Mental and neurological diseases including depression, Parkinson’s disease, dementia, epilepsy, anxiety disorders and bipolar disorders account for a considerable amount of the world’s disease burden. Unfortunately, drugs used in the treatment of neurological diseases are expensive, symptomatic and they produce undesirable side effects. People from different cultures prefer to use medicinal plants for the treatment of various ailments ranging from plain to perplex disorders because they are most affordable, cost effective and easily accessible source of treatment in the primary healthcare system throughout the world. Withania coagulans, an erect grayish under-shrub belongs to family Solanaceae. It is common in Pakistan, East India, Iran and Afghanistan. The objective of this study was to analyze the anti-seizure activity of crude methanolic extract of Withania coagulans fruits (MeWc). For screening of this activity, maximal electroshock seizures model (MES) and chemically-induced seizures models were used. In maximal electroshock seizures test MeWc showed significant dose dependent percent protection against hind-limb tonic extension; significant and dose-dependent increase in latency to myoclonic jerks and tonic clonic convulsions and decrease in seizures duration were observed in PTZ-induced seizures. In strychnine-induced convulsions MeWc significantly increased latency to hind-limb tonic extension and percent protection from death in a dose-dependent manner. Thus, it was inferred from the experiments that extract of Withania coagulans showed anticonvulsant activity.

The current antiseizure drugs present with side effects, some of which can lead to discontinuation of epilepsy pharmacotherapy, and a sizeable number of other drugs being less efficacious. Medicinal plants are used for the treatment of epilepsy in Nigeria. The aim of this study is to evaluate the anticonvulsant activity of the stem bark extract of Trichilia roka in mice and chicks. Anticonvulsant screening was carried using pentylenetetrazole (PTZ), strychnine (STN) and picrotoxin (PCT) induced seizures while Maximal electroshock (MEST) test in day old chicks. Preliminary phytochemical screening of the extracts was carried out on the extract using conventional protocols. The LD50 was determined in mice. The intraperitoneal LD50 was calculated to be 118.32 mg/kg in mice. Flavonoids, tannins, alkaloids, saponins, glycosides, anthraquinones and steroids were found to be present. Significant (p≤0.05) prolongation of the mean onset of seizures was recorded with Trichilia roka (15 and 30 mg/kg) compared with normal saline treated groups in PTZ induced seizures. Trichilia roka at all the doses tested did not significantly reduce the mean recovery time of seizures induced by MEST. The extract at 7.5 and 15 mg/kg prolonged the latency of convulsion induced by STN. The extract failed to show significant prolongation of the latency of seizures induced by picrotoxin. It can then be inferred, that Trichilia roka contained bioactive constituents that are beneficial in petit mal epilepsy and justify their use in Traditional Medicine.

Objective: To evaluate the antiepileptic activity of ethanolic extract of Azima tetracantha root (EEATR) against Maximal electroshock (MES) and Pentylene tetrazole (PTZ) induced seizures in mice.Methods: 48 adult male mice were used and 4 groups with six in each were allocated to each model. 4 Groups are divided into control, standard and two test groups. Control group received normal saline, standard group, Sodium valproate-200 mg/kg and the two test groups received ethanolic extract of roots of Azima tetracantha (EEATR) 250 and 500 mg/kg respectively. Antiepileptic activity was assessed based on hind limb tonic extension duration, onset of convulsions and mortality. The results were compared with control and standard.Results: In MES model EEATR reduced the duration of hind limb extension (HLE) and seizure protection was 50% and 66.6% with 250 and 500 mg/kg respectively. In PTZ model both the doses of EEATR delayed the onset of clonic phase and prevented death in 50% of animals in group treated with 500 mg/kg EEATR, similar to sodium valproate. Results were analyzed by ANOVA with p<0.05 considered as significant.Conclusion: EEATR has shown anticonvulsant activity in both MES and PTZ models. 500 mg/kg of EEATR has better protection than 250 mg/kg against seizure in MES model and equally efficacious as sodium valproate standard in PTZ model.

Objective: In the present study, three different extracts of Pemna herbacea (Roxb.) were evaluated for its anticonvulsant activity against pentylenetetrazol (PTZ) and maximal electroshock (MES)-induced convulsions in mice.Methods: The shed-dried powder of P. herbacea roots was passed through a sieve and subjected to extraction using Soxhlet apparatus with 70% ethanol, petroleum ether, and chloroform to get respective extracts named as ethanolic extract of P. herbacea, petroleum ether extract of P. herbacea, and chloroform extract of P. herbacea (PHC). Preliminary phytochemical analysis and acute oral toxicity study were done. Thereafter, the extracts were analyzed for PTZ- and MES-induced convulsions.Results: The results revealed that PHC at the doses 200 and 400 mg/kg was effective against both, i.e., PTZ- and MES-induced convulsions. Overall PHC 400 mg/kg was most effective, as it significantly delayed onset of convulsions (p<0.01) and reduced % mortality (50%) in PTZ model, while in MES model, it showed the highest reduction in duration of hind limb extension (p<0.01) and percentage protection (33.33%).Conclusion: The results reported anticonvulsant potential of PHC against both PTZ- and MES-induced convulsions suggesting mixed mechanism of action which may be attributed to different phytochemicals acting simultaneously.
