Abstract
Abstract
Background
Anxiety is a common ailment of high co-morbidity with epilepsy, a chronic neurologic disease characterized by recurrent seizures. Current drugs used for these conditions have several limitations such as disabling side effects, relapse, and ineffectiveness in certain population necessitating the search for alternative options. The aqueous leaf extract of Cymbopogon citratus (CYC) is widely used for its various health-promoting effects including relief of seizures and anxiety in ethnomedicine. This present study describes its effects on convulsions, anxiety-like behaviors, and social interaction in mice.
Methods
Male Swiss mice were pretreated orally with CYC (25, 50, and 100 mg/kg), diazepam (1 mg/kg), or distilled water (10 mL/kg) 60 min before induction of convulsions with intraperitoneal (i.p.) injection of picrotoxin (10 mg/kg), pentylenetetrazole (PTZ; 85 mg/kg), or isoniazid (300 mg/kg). The animals were then observed for the occurrence of seizure for 30 min or 2 h for isoniazid. The effects of CYC on anxiety-like behaviors, social interaction, and spontaneous motor activity (SMA) were evaluated in naive mice.
Results
CYC (25–100 mg/kg) did not prevent convulsions nor delay the latency to convulsions induced by picrotoxin, PTZ, or isoniazid. Pretreatment with CYC (50 and 100 mg/kg, p.o) produced anxiolytic-like effect, decreased SMA, and also enhanced social interaction behavior in naive mice.
Conclusions
The results of this study suggest that CYC did not exhibit an anticonvulsant property in mice injected with picrotoxin, PTZ, or isoniazid, but its anxiolytic-like activity and social interaction-promoting effect might be of benefit as an adjuvant in improving the quality of life of epileptic patients.
