Elaeocarpus ganitrus: its beneficial antiparkinsonian effect in MPTP induced motor and non-motor impairments in mice.

ABSTRACT

Aim: Elaeocarpus ganitrus (Family Elaeocarpaceae), has shown beneficial role in the treatment of depression, convulsions and asthma. This study was undertaken to evaluate the antiparkinson effect of E.ganitrus. Materials and methods: Swiss albino mice of either sex were divided into 06 groups (n =12). 1st group mice were given 0.5% carboxy methyl cellulose (orally), 2nd group were administered MPTP (2 doses, each dose 20 mg/kg at 2 hr. interval, i.p.). Whereas 3rd, 4th and 5th groups - were administered with E. ganitrus (100, 200, and 400 mg/kg/day, orally), respectively, along with MPTP. Group 6- received Levodopa (30mg/kg, i.p,) along with MPTP. To evaluate anti-Parkinson effect, hanging wire test, tardive dyskinesia test and elevated plus maze test were performed on the1st day and on 8 th day. One way ANOVA followed by post-hoc Tukey test, with p<0.05 was considered statistical significant. Results: E.ganitrus (200 and 400 mg/kg, p.o.) was found to increase the hanging time significantly (p <0.001) in hanging wire test and significantly decreased (p <0.001) the Vacuous Chewing Movements (VCMs) in tardive dyskinesia test as compared to MPTP group. E.ganitrus (200 and 400 mg/kg, p.o.) was found to significantly increase (p <0.001) the no. of entries and time spent in open arm and significantly decreased the no. of entries and time spent in closed arm (p <0.001) compared to MPTP treated group. Conclusion: The results of the present study conclusively showed that E.ganitrus has beneficial effect in MPTP induced experimental model of Parkinson’s disease.
