ABSTRACTObjective: To assess the anticonvulsant activity of ethanolic extract of Citrus maximus (EECM) leaves of maximal electroshock seizure (MES) andpentylenetetrazol (PTZ)-induced seizure models on albino (Wistar strain) rats and mice.Methods: Anticonvulsant activity was carried out by MES model and PTZ-induced clonic convulsions model; in each model, albino rats (Wistar strain)of either sex were taken and divided into five groups, each consisting of 6 rats. One group was used as control (3% w/v gum acacia), one as standard(phenytoin), and three groups for the test drug of EECM leaves (doses of 50, 100, and 200 mg/kg) treatment. The reduction in time or abolition of tonicextensor phase of MES-convulsions was recorded for all the animals. In PTZ model, either delay or complete abolition of convulsions in rats treatedwith diazepam and EECM leaves was noted for all the animals.Result: EECM leaves reduced the extensor phase of convulsion in MES in a dose-dependent manner and decrease in the duration of convulsions in PTZmodel with increasing dose. Anticonvulsant activity was seen maximum at the dose of 200 mg/kg.Conclusions: Thus, from the above two seizure models of MES and PTZ, it can be concluded that EECM leaves have got an anticonvulsant effect in anincreasing dose-dependent manner.Keywords: Anticonvulsant, Citrus maximus, Maximal electroshock seizure, Pentylenetetrazol.

Introduction: Phenytoin is widely used in treatment of generalised tonic clonic seizures but its adverse effects make its usage limited. Hence forth, there is a need for newer antiepileptics. Studies have shown antiepileptic property for nebivolol in combination with phenytoin hence, reducing the dosage of phenytoin and its adverse effects and toxicities. Aim: To evaluate the anticonvulsant property of nebivolol alone and in combination with phenytoin against Maximal Electroshock Seizures (MES) in a mouse model. Materials and Methods: This was an experimental animal study on total of 36 swiss albino male mice were randomly assigned to six groups with six animals in each group in December 2019 at Sri Manakula Vinayagar Medical College and Hospital. Group 1 was considered as normal control, Group 2 received Phenytoin 25 mg/kg Intraperitoneal (IP); Group 3 & 4 received Nebivolol 0.25 mg/kg oral & 0.50 mg/kg oral, respectively; Group 5 received 12.5 mg/kg IP and nebivolol 0.25 mg/kg oral; Group 6 received Phenytoin 12.5 mg/kg IP and nebivolol 0.50 mg/kg oral. Anticonvulsant effect of the drugs nebivolol and phenytoin was elicited in mice by MES test. After induction following parameters were recorded for onset of Tonic Hind Limb Extension (THLE), duration of clonus, duration of THLE, number of jerks, recovery time. Statistical analysis was done by ANOVA followed by post-hoc Dunnett t-test. Results: Significant reduction in duration of THLE (p<0.01) and clonus (p<0.001) was observed in the group treated with phenytoin (12.5 mg/kg) and nebivolol (0.50 mg/kg). Conclusion: The present study concludes that the lower dose of phenytoin in combination with nebivolol can reduce seizures induced by MES in mice model.

Humboldtia vahliana Wight, Ic.tt belongs to the family Caesalpiniaceae is an unarmed erect small tree, commonly called as Attuvanchi in Malayalam. Stem bark which is used in the treatment of apasmara by tribal healers of Urulanthanni area, Ernakulum district in Kerala, India. Apasmara of Ayurveda aptly comes under the epilepsy of modern literature, especially under tonic-clonic / generalized seizure. Epilepsy (Apasmara) is an electrical disturbance resulting from sudden, recurrent, and disorderly discharge of neurotransmitter in brain cells. The prevalence of epilepsy has been estimated at 5-10 persons per1000. In this study ghee prepared with Humboldtia vahliana (GHV) was tested for chronic anticonvulsant effect by Maximal electro shock seizure test in female wistar albino rats (150-200mg). The experiment was carried out with 5 groups having 6 albino rats per group. ‘Phenytoin’ was given to the standard group. Group I, III, IV, V were given distilled water, vehicle (cow’s ghee), effective dose of GHV, double dose of GHV respectively. Complete abolition or reduction time (in seconds) of hind limb extension is considered as anticonvulsant activity of drug. At the end of experiment effective dose of GHV and double dose of GHV showed significant chronic anticonvulsant action as compared with vehicle and control. Group IV (effective dose) was able to reduce the Time of Tonic Hind Limb extension (THE) by 44.34%with p value 0.007 (compare with control). Group V (double dose) was able to reduce the Time of Tonic Hind Limb extension by 59.53% with p value 0.004 (compared with control). This change was statistically significant at p<0.05.

The present study is objected to evaluate the anticonvulsant activity of the phosphodiesterase III inhibitor cilostazol in the animal model of epilepsy. Conventional anti-epileptic rodent models like Maximal Electric Shock (MES)- induced convulsions and Pentylenetetrazol (PTZ) induced convulsions were used. The animals were randomly divided into six groups, with six rats in every group. Here anti-epileptic activity of cilostazol with two different doses (10 mg/kg i.p and 20 mg/kg i.p) was compared with standard drug and standard drug + Cilostazol two different doses (10 mg/kg i.p and 20 mg/kg i.p). Cilostazol (20 mg/kg i.p) exhibited an anticonvulsant effect in MES-induced and PTZ induced convulsion models over the Control group and cilostazol (10 mg/kg i.p). Standard drugs were shown superiority in seizure suppression activity than cilostazol (20 mg/kg i.p). The time duration of onset of clonic convulsion and period of clonic convulsions in PTZ induced convulsion were increased and decreased respectively when compared to Standard drug + cilostazol both doses and standard drug alone. Phenytoin abolished convulsions induced by MES- convulsion model. So the present study established that cilostazol has low anticonvulsant efficacy in comparison with conventional drugs (Phenytoin and Sodium Valproate). The potentiating effect of cilostazol with standard drugs was also demonstrated.

Objective: To compare anticonvulsant activity of methanol extracts of Sapindus emarginatus (MESE) and Acorus calamus (MEAC) in experimental seizure models in mice. Methods: Hind limb tonic extension (HLTE) in Maximal electroshock (MES) seizure and clonic seizure in Pentylenetetrazol (PTZ) seizure models were assessed. Group I (control) mice received 1% gum acacia in distilled water (1 ml/100 g). Topiramate (50 mg/kg) was administered in group II (standard) animals. Group III and IV mice were treated with 200 and 400 mg/kg of MESE, respectively. Mice in group V and VI were given MEAC at the dose of 200 and 400 mg/kg, respectively. Drugs were given orally suspended in 1% gum acacia suspension (1 ml/100 g) for 7 d. Next day after 1 h of drug administration, the seizure was induced for evaluation. Results: Anticonvulsant property of both extracts was confirmed by reduction (p<0.001) in HLTE phase in MES model; delayed onset of the clonic seizure (p<0.001) and its shortened phase (p<0.001) in PTZ model when compared with the control. MESE-200 mg/kg produced significantly longer (p<0.001) HLTE phase with lower protection (40.34%) among the different doses of the extracts. Clonic seizure onsets and durations in PTZ model were comparable among the different extract-treated groups; however, mortality was higher (66.6%) with MESE-200 mg/kg. Conclusion: Anticonvulsant activity of MESE and MEAC was evident; however, MESE at the dose of 200 mg/kg was less effective.

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.
