[ 1 ] - Acute and chronic effects of lithium on BDNF and GDNF mRNA and protein levels in rat primary neuronal, astroglial and neuroastroglia cultures
Objective(s):Theneuroprotective effect of lithium has been attributed to its therapeutic action. However, the role of glial cells particularly astrocytes, and the possible interactions between neurons and astrocytes in neuroprotective effects of lithium have been disregarded. Thus, the aim of this study was to evaluate the direct effects of lithium on brain derived neurotrophic factor (BDNF) an...
[ 2 ] - CYP2A6 genetic polymorphism and its relation to risk of smoking dependence in male Iranians
Introduction: Nicotine is the psychoactive substance responsible for establishing and maintaining smoking dependence. CYP2A6 is the primary enzyme that inactivates nicotine to cotinine .Genetic variation in CYP2A6 accounts for some of the inter-individual variability in nicotine metabolism and has been indicated to influence smoking behavior and dependence. Therefore, the aim of this study was ...
[ 3 ] - اثر تجویز تحت مزمن عصاره های آبی و هیدروالکلی زعفران استهبانات فارس در تست شنا در موش سوری
زمینه وهدف: در طب سنتی ایران، از زعفران به عنوان یک گیاه شادی بخش نام برده شده است. هدف این مطالعه بررسی اثر ضد افسردگی عصاره های آبی و هیدرو الکلی زعفران استهبانات فارس در تجویز تحت مزمن بود. روش بررسی: در این مطالعه تجربی اثر تزریق درون صفاقی دوزهای، 50، 100، 200 و400 میلی‌گرم بر کیلوگرم عصاره آبی و 100، 200، 400 و 800 میلی‌گرم بر کیلوگرم عصاره هیدرو الکلی کلاله زعفران به صورت تجویز تحت م...
[ 4 ] - Acute and Chronic Effects of N-acetylcysteine on Pentylenetetrazole-induced Seizure and Neuromuscular Coordination in Mice
Background: N-acetylcysteine (NAC) has been indicated against experimental seizures, but with relatively inconclusive results. This study was undertaken to evaluate whether NAC exerts a dose-dependent anticonvulsant effect and to determine NAC safe therapeutic dose range and its muscle-relaxant activity in both acute and chronic uses.Methods: Following intraperitoneal (i.p.) administration of N...
[ 5 ] - Increased bcl-2 Protein Levels in Rat Primary Astrocyte Culture Following Chronic Lithium Treatment
Background: B cell CLL/lymphoma 2 protein, bcl-2, is an important anti-apoptotic factor that has been implicated in lithium’s neuroprotective effect. However, most studies have focused on assessing the effects of lithium in neurons, ignoring examination of bcl-2 in astrocytes, which also influence neuronal survival and are affected in bipolar disorder. The aim of this study was to evaluate whet...
[ 6 ] - Anticonvulsant Effect of Guaifenesin against Pentylenetetrazol-Induced Seizure in Mice
Background: There have been some reports about the possible N-methyl-D-aspartate (NMDA) antagonist activity of Guaifenesin. As drugs with a similar structure to Guaifenesin (i.e. Felbamate) and those with NMDA antagonist activity have been clinically used as anticonvulsants, the aim of this study was to determine whether Guaifenesin has an anticonvulsant effect in an animal model of seizure. ...
[ 7 ] - Anticonvulsant Effect of the Aqueous Extract and Essential Oil of Carum Carvi L Seeds in a Pentylenetetrazol Model of Seizure in Mice
Background: Carum carvi L. (caraway), known as black zeera in Iran, has been indicated for the treatment of epilepsy in Iranian folk medicine. This study evaluated whether the aqueous extract and essential oil of caraway seeds have anticonvulsant effects in mice.Methods: The anticonvulsant effects of the aqueous extract (200, 400, 800, 1600, and 3200 mg/kg, i.p.) and essential oil (25, 50, 100,...
[ 8 ] - Curcumin Improves Memory Impairment and Restores Irregular Neuronal Distribution In the Hippocampal CA1 Region After Global Cerebral Ischemia in Male Rats
Purpose: Global Cerebral Ischemia (GCI) causes neuronal damage that leads to neurological and cognitive impairments. Curcumin has anti-inflammatory, antioxidant and neuroprotective properties which makes it a potential candidate for improving GCI-induced impairments. The aim of this study was to investigate the effects of curcumin on the neurological and memory deficits as well as spatial neuro...
[ 9 ] - Glycogen synthase kinase-3β may contribute to neuroprotective effects of Sargassum oligocystum against amyloid-beta in neuronal SH-SY5Y cells
Glycogen synthase kinase (GSK)-3β mediates amyloid-beta (Aβ) and oxidative stress-induced neurotoxicity in neurodegenerative disorders. Natural products with antioxidant activity, such as Sargassum (S.) oligocystum may modulate GSK-3β enzyme and protect against Aβ-induced neurotoxicity. Therefore, we aimed to assess the neuroprotective effects of a methanolic extract of S. oligocystum against A...
