ANTI- CONVULSANT PROFILE OF AQUEOUS EXTRACT OF SAPINDUS LAURIFOLIA IN EXPERIMENTAL ANIMALS

Objective: The aim of the present study was to evaluatethe anti convulsant property of aqueous extract of Sapindus laurifolia in Pentylenetetrazole (PTZ) and MES induced convulsions in experimental models. Materials & Methods: The purpose of this study is to explore the anticonvulsant activity of ethanolic extract of Momordica tuberosa using Pentylenetetrazole and maximal electric shock induced convulsions in rats. MES Model: rats were divided into 4 groups of 6 rats each. GROUP-I (NC) received 2% GA 2ml, GROUP-II (STD) received Phenytoin 25mg/kg, GROUP-III, IV received low dose (300 mg/kg) & high dose (600 mg/kg) of Sapindus laurifolia respectively orallyConvulsions were produced in all groups by giving maximal electric shock  of 150 mA for 0.2sec after 1 hour of giving test and standard drugs orally. Tonic clonic seizures were produced after giving electric shock. Recovery time was noted. The percentage of inhibition of convulsions by drugs was measured and compared between the control, standard and test. PTZ model: Rats weredivided and test drugs were given same as above model but standard drug was Sodium valproate (50mg/Kg). Convulsions were induced by giving the Pentylenetetrazole IP 1 hr after giving test and standard drugs intraperitoneally (IP). The onset of convulsions, duration of action, and type of seizures were noted and compared between standard and test groups. Results: In MES Model, ethanolic extract of Sapindus laurifolia significantly (p<0.001) decreased the duration of tonic clonic seizures and recovery time. The percentage of inhibition was 66%. In PTZ Model the onset of seizures was delayed (p<0.002) with low and high doses and the duration of convulsions was reduced effectively (p<0.001). Type of seizure was controlled in initial phase and number of seizures was also reduced. Conclusion:  Sapindus laurifolia was shown anticonvulsant property in both MES and PTZ animal models.
