[ 1 ] - اثر تجویز حاد مهار کننده های کانال های پتاسیمی بر علایم رفتاری پارکینسونیسم القا شده با 6-هیدروکسی دپامین در موش صحرایی
زمینه و هدف: 4-آمینوپیریدین (4-AP) و تترااتیل آمونیوم (TEA) دو مهار کننده کانال های پتاسیمی می باشند؛ که اثرات سودمندی در درمان برخی بیماری های نورولوژیک همچون مولتیپل اسکلروزیس، اتاکسیا و الزایمر نشان داده اند. در این مطالعه اثر تجویز حادّ 4-AP و TEA در درمان علایم رفتاری پارکینسونیسم القا شده با سم 6- هیدروکسی دپامین (6-OHDA) درموش های صحرایی نر مورد بررسی قرار گرفت. مواد و روش ها: سم 6-هیدر...
[ 2 ] - مصرف بالای کمپلکس ویتامین‌های ب شدت پارکینسونیسم القاء شده توسط سم 6-هیدروکسی دپامین در موش صحرایی را کاهش می‌دهد
Background and Objective: Several lines of evidence show that high plasma level of homocysteine (Hcy) induces development or exacerbates Parkinson’s disease. B vitamins are necessary for Hcy metabolism and control plasma level of Hcy. In the present study, we studied the effect of B vitamin supplementation on the 6-hydroxydopamine (6-OHDA)-induced Parkinsonism in rat. Materials and ...
[ 3 ] - Normobaric hyperoxia preconditioning attenuates streptozotocin - induced impairments in spatial learning
Introduction: A large body of evidence points to oxidative stress as prime candidate mediating the behavioral impairments and memory deficits in Alzheimer's disease (AD). It has been demonstrated that hyperoxia preconditioning activates complex endogenous neuroprotective mechanisms including an increase in capacity of antioxidant defence mechanisms. The aim of this study was to investigate the ...
[ 4 ] - High intake of folic acid attenuates 6-hydroxydopamine-induced Parkinsonism
Introduction: High levels of homocysteine (Hcy) might accelerate dopaminergic cell death through oxidative stress and excitotoxicity. Folate plays an important role in the control of plasma levels of Hcy. In this study, effect of supplementation with folic acid on the 6-hydroxydopamine (6-OHDA)-induced Parkinsonism in rat and also serum level of Hcy was investigated. Methods: Rats were fed ...
[ 5 ] - The Role of Orexin-A in Water Intake in Water-deprived Rats
Background: The lateral hypothalamus (LH), which produces orexin, is vital for body solution homeostasis. Lateral hypothalamus (LH) lesion causes adipsia and its stimulation increases water intake. Objective: This study aimed to investigate the effect of an intracerebroventricular (ICV) injection of orexin-A (OXA) on water-drinking behavior in water-deprived rats. Metods: A total of 32 male W...
