introduiction: this study aimed to investigate the protective effects of 12-week voluntary exercise using a running wheel on the striatum  dopaminergic neurons against 6-hydroxydopamine lesions in rats. materials and method: twenty five rats were divided into three groups including healthy, parkinson and training-parkinson. the training groups were housed in individual cages geared with running...

introduction: parkinsonrquote s disease (pd) is a human neurodegenerative disorder which is associated with a massive and progressive degeneration of dopaminergic neurons in subistantia nigra (sn). there is a strong evidence of an oxidative stress participates in the etiology of pd. materials and methods: the rats were divided into sham-operated, experimental and vitamin e-treated groups. for a...

Background and Objective: The purpose of this study was to investigate the preconditioning effect of aerobic exercise with vitamin D3 consumption on vascular endothelial growth factor (VEGF) level in the 6-hydroxydopamine (6-OHDA)-lesioned rat model of Parkinson’s disease. Materials and Methods: Forty-eight male rats weighing 250-300 g were randomly assigned to 6 groups: healthy control, Parkin...

Oxidative stress is a major pathophysiological mediator of degenerative processes in many neurodegenerative diseases including Parkinson's disease (PD). Aberrant cell signaling governed by protein phosphorylation has been linked to oxidative damage of dopaminergic neurons in PD. Although several studies have associated activation of certain protein kinases with apoptotic cell death in PD, very ...

Background and objectives: Parkinson's disease (PD) is a common neuropathologic disorder that is caused by degeneration of dopaminergic neurons of dense part of nigra. Oxidative stress has been found in the pathophysiology of PD. Since α-pinene has strong anti-oxidant effects, the purpose of this research was to study its effects on movement disorders and memory and lipid perox...

abstractintroduction: parkinson's disease (pd) is a neuropathological disorder involving the degeneration of dopaminergic neurons in the substantia nigra, with the subsequent loss of their terminals in the striatum. quercetin, a natural flavonoid, is a strong antioxidant and radical scavenger. therefore, its neuroprotective effect in a model of parkinson’s disease in rat was evaluated.meth...

Background & Aims: With regard to the neuroprotective effect of creatine in some neurological disorders like cerebral ischemia, this study was conducted to evaluate the effect of creatine in an experimental model of Parkinson’s disease (PD). Involvement of oxidative stress was also assessed. Methods: In this experimental study, male rats (n = 40) were divided into 5 groups, i.e. sham-operated (...
