Comparison between the efficacies of pomegranate with different combinations against development of
parkinsonism using rotenone model in rats
Background: Parkinson’s disease (PD) is a geriatric neurodegenerative disorder marked by the gradual loss of the ability to
control physical movements. Exposure to different environmental agents including rotenone (RT) has been linked to increased
degeneration and risk of PD. The gold standard effective therapy in PD is L-dopa despite its long-term treatment side effects.
In medical folklore, Pomegranate (POM) has been extensively referenced due to its dopaminergic neuroprotective effect while
Vinpocetine (VIN) is claimed to enhance brain neurotransmitter, glucose, and oxygen consumption as well as cerebral blood
flow. Propolis has been also demonstrated for treatment and prevention of PD while Cocoa can reduce associated symptoms as
stress, depression and promote better memory.
Objective: To evaluate and compare the efficacy of POM together with each of VIN, Propolis, Cocoa or L-dopa with L-dopa
alone using RT-induced PD rat model.
Methods: Rats were divided into six groups: one normal and five RT model groups. One of RT (2.5mg/kg SC) groups served as
non-treated PD model while the others were treated with either L-dopa (10mg/kg PO) or with POM (150mg/kg PO) together
with each of the following; Vin (20mg/kg PO), Propolis (300mg/kg PO), Cocoa (24mg/kg PO) or L-dopa (10mg/kg PO) all for
19 days. Motor and cognitive performances were examined using three tests (catalepsy, open-field, Y-maze). Striatal dopamine,
norepinephrine, serotonin, and acetylcholinesterase were assessed as well as mitochondrial complex-1, MDA, SOD, TAC, IL-1β,
TNF-α, and caspase-3 expression. In addition, histopathological examinations of different brain regions were also determined.
Results: Concurrent treatment with L-dopa alone or with all POM combination groups ameliorated the impairments in
locomotor activities as well as cognition and attenuated the depletions in monoamines and mitochondrial complex-1 contents.
In addition, the elevations in acetylcholinesterase activity, oxidative stress, and inflammatory markers as well as caspase-3
expression induced by RT were also decreased.
Conclusion: Combinations of POM with each of VIN, Propolis or Cocoa have beneficial effects against the development of
PD and represent a promising disease-modifying therapy even without given as an adjuvant to L-dopa, consequently can be
recommended in protection or in treatment course especially when given early.
