Background And Objective
Parkinsons disease (PD) is a common neurological disorder due to degeneration of dopaminergic neurons within pars compacta of substantia nigra (SNC). With regard to protective effect of Malva sylvestris (MS), this study was conducted to evaluate the effect of aquaeous extract of this plant in an experimental model of PD induced by 6-hydroxydopamine (6-OHDA).Materials And Methods
Rats were divided into sham-operated, MS-treated sham-operated, lesioned and MS-treated lesioned groups. The hemi-PD early model was induced by unilateral intrastriatal injection of 6-OHDA (12.5 µg/5µl of saline-ascorbate, left side). The treated groups received aquaeous extract of MS (i.p.) at a dose of 100 mg/kg once a day for one week at an interval of 24 h till 1 h pre-surgery. One week after surgery, the animals were tested for rotational behavior by apomorphine for an hour and the number of dopaminergic neurons in the SNC was counted.Results
After one week, apomorphine caused a significant contralateral turning (PConclusion
Intraperitoneal administration of aquaeous extract of Malva sylvestris could reduce motor asymmetry and has not neuroprotective effect against 6-OHDA toxicity in an experimental model of PD. Keywords:
