The anticonvulsant effect of the hydroalcoholic extract of Zizyphus jujuba (HEZJ) fruit (100, 250, 500, and 1000 mg/kg, orally) was evaluated in experimental seizure models in rats. The effect of HEZJ on seizure-induced cognitive impairment, oxidative stress, and cholinesterase activity was also investigated. HEZJ (1000 mg/kg) exhibited maximum protection(More)
The present study investigates the effect of chronic curcumin administration on phenytoin-induced cognitive impairment and oxidative stress in rats. Male Wistar rats were administered drugs/vehicle for 21 days. Learning and memory was evaluated using the passive avoidance paradigm and the elevated plus maze. On day 21, serum phenytoin concentrations and(More)
The present study investigates the interaction of curcumin with four antiepileptic drugs (AEDs) in male Wistar rats. In the first protocol, seizures were induced using pentylenetetrazole (PTZ) and valproate was injected intraperitoneally (i.p.) in therapeutic and sub-therapeutic doses 30min before PTZ administration. Curcumin was co-administered with(More)
AIM Epilepsy as well as chronic use of most antiepileptic drugs predisposes to cognitive impairment. Curcumin has been reported to possess antioxidant, anticonvulsant as well as neuroprotective potential. Hence, this study was conducted to evaluate the effect of curcumin against seizures, cognitive impairment and oxidative stress in(More)
The antiepileptic drugs, phenobarbitone and carbamazepine are well known to cause cognitive impairment on chronic use. The increase in free radical generation has been implicated as one of the important mechanisms of cognitive impairment by antiepileptic drugs. Curcumin has shown antioxidant, anti-inflammatory and neuro-protective properties. Therefore, the(More)
Evolvulus alsinoides, also known as Shankpushapi, is a commonly used traditional medicine for enhancing memory. We evaluated the in vitro free radical scavenging and enzymes [acetylcholinesterase, butyrylcholinestrase, glycogen synthase kinase-3-β (GSK-3-β), rho kinase (ROCK II), prolyl endopeptidase (PEP), catechol-O-methyl transferase (COMT) and(More)
Clitoria ternatea, commonly known as Aparajita, is used as Medhya rasayana in Ayurveda. The role of C. ternatea in experimental models of cognitive impairment is yet to be explored. The present study was designed to study the effect of aqueous and hydroalcoholic extracts of C. ternatea on biochemical and behavioral parameters related to cognitive impairment(More)
Alzheimer's disease (AD) is an age-dependent neurodegenerative disease constituting ~95% of late-onset non-familial/sporadic AD, and only ~5% accounting for early-onset familial AD. Availability of a pertinent model representing sporadic AD is essential for testing candidate therapies. Emerging evidence indicates a causal link between diabetes and AD.(More)
Cough is the most common symptom of respiratory diseases. When cough becomes serious, opioids are effective, but they have side effects like sedation, constipation, some addiction liability and also compromise the respiratory function. Therefore, there is need to have effective anti-tussive agent which do not have respiratory suppressant activity. The(More)
In the present study we investigated the anti-amnesic activity of Vitex negundo in scopolamine induced amnesia in rats. Wistar rats (180-200 g) were trained on active avoidance task. Each animal received session of 15 trials with inter trial duration of 15 s for 5 days. Scopolamine (3 mg/kg, i.p) was administered at different time periods on the basis of(More)
