This study examined whether catecholamine-mediated signals in the anterior cingulate cortex (ACC) contribute to effort-based decision making. Rats were tested after 6-hydroxydopamine or vehicle infusions into the ACC in a T maze cost-benefit task in which the rats could choose either to climb a barrier to obtain a high reward in one arm or run into the other arm without a barrier to obtain a lo...
بیماری پارکینسون بعد از آلزایمر ، شایع ترین بیماری دژنراسیون به حساب می آید.بیماری پارکینسون برای اولین بار توسط دانشمند بریتانیایی دکتر جیمز پارکینسون در سال ???? میلادی توصیف شد. هنوز اتیولوژی این بیماری شناسایی نشده است ولی از نظر پاتولوژی این اختلال هنگامی رخ می دهد که نواحی خاصی از مغز توانایی خود را در تولید دوپامین از دست می دهند در سال1960 نشان داده شده که بیماری پارکینسون ناشی از آسیب ...
Introduction: Parkinson's disease (PD) is a common neurodegenerative disorder characterized by progressive neuronal dysfunction. Growing evidence has shown that oxidative stress plays a crucial role in the pathogenesis of Parkinson's disease. Correspondingly, the current study evaluated the protective effect of topiramate in 6-hydroxydopamine induced oxidative stress and apoptosis in PC12 cells...
The effect of 6-hydroxydopamine on repeated nicotine-induced tail-tremor was investigated in rats. Tail-tremor induced by nicotine (0.5 mg/kg/day, subcutaneously) became more pronounced in intensity with daily administration for 9 days. Rats pretreated with 6-hydroxydopamine (250 micrograms, intracerebroventricularly) showed almost the maximum degree of tail-tremor during the whole experimental...
In the present study, PC12 cells induced by 6-hydroxydopamine as a model of Parkinson's Disease, were used to investigate the protective effects of bone marrow-derived mesenchymal stem cells bone marrow-derived mesenchymal stem cells against 6-hydroxydopamine-induced neurotoxicity and to verify whether the mechanism of action relates to abnormal α-synuclein accumulation in cells. Results showed...
