[ 1 ] - The effects of aqueous cinnamon bark extract and cinnamaldehyde on neurons of substantia nigra and behavioral impairment in a mouse model of Parkinson’s disease

Background and Objective: Parkinson's disease (PD) is characterized by a progressive loss of dopaminergic neurons in substantia nigra. In recent years, there have been interests in the role of the free radical damage in PD. Cinnamon and its derivative, cinnamaldehyde acts as powerful antioxidant and anti-inflammatory agents. This research focused on the effects of cinnamon extract and cinnamald...

[ 2 ] - Ellagic acid attenuates enhanced acetylcholinesterase reactivity in an experimental model of Alzheimer′s disease induced by beta amyloid25-35 in the rat

Background and Objective: Alzheimer’s disease (AD) is a multifactorial disease with debilitating consequences and few therapeutic strategies exist for it. With regard to antioxidant capacity and anti-β-amyloid polymerization potential of ellagic acid, this study was conducted to evaluate the effect of this substance on enhanced acetylcholinesterase reactivity in an experimental model of Alzheim...

[ 3 ] - Antinociceptive activity of Tribulus terrestris oral feeding in diabetic rats: Involvement of lipid peroxidation

Background and Objective: Due to the presence of some evidence for anti-diabetic and antioxidant activity of Tribulus terrestris (TT), this study was designed to investigate the anti-nociceptive effect of TT in streptozotocin-diabetic rats using formalin test and hot tail immersion tests. Materials and Methods: Rats were divided into control, TT-treated control, diabetic, sodium salicylate (SS)...

[ 4 ] - Administration of Salvianolic Acid B Attenuates Learning and Memory Deficits in Diabetic Rats: Involvement of Oxidative Stress

Background and Objective: Based on the effect of chronic metabolic diseases including diabetes mellitus on the learning and memory, this study was designed to assess the usefulness of administration of salvialonic acid B on lessening of learning and memory deficits in streptozotocin (STZ)-diabetic rats. Materials and Methods: Male Wistar rats were allocated into control, salvialonic acid B-trea...

[ 5 ] - Melissa officinalis aqueous extract ameliorates 6-hydroxydopamine-induced neurotoxicity in hemi-parkinsonian rat

ABSTRACT Background and Objective: Parkinson's disease (PD) is an age-related neurodegenerative disorder with massive loss of dopaminergic neurons in the substantia nigra pars compacta. L-Dihydroxyphenylalanine (L-DOPA) substitution is still the gold standard therapy for PD. However, there has been little information available on neuroprotective and regenerative therapies for PD. Due to the neu...

[ 6 ] - The effect of simvastatin in prevention of histological changes of substantia nigra and behavioral abnormalities in an experimental model of Parkinson’s disease in rat

Background and Objective: Parkinson’s disease (PD) is a rather common neurological disorder in elders that is due to degeneration of dopaminergic neurons within mesencephalic substantia nigra pars compacta. With regard to protective and antioxidant effect of simvastatin, this study was conducted to evaluate its neuroprotective effect in an experimental model of PD. Materials and Methods: In thi...

[ 7 ] - Antidiabetic effect of Teucrium polium aqueous extract in multiple low-dose streptozotocin-induced model of type 1 diabetes in rat

Background and Objective: Teucrium polium (TP) has shown hypoglycemic effect in type 1 diabetes induced by single high dose of the cytotoxic agent streptozotocin (STZ) in rats. This study was conducted to evaluate whether its aqueous extract could have such an effect in multiple low-dose STZ-induced model of type 1 diabetes in rats. Materials and Methods: Male Wistar rats were divided into cont...

[ 8 ] - Diabetic Encephalopathy Affects Mitochondria and Axonal Transport Proteins

Introduction: Diabetic encephalopathy is described as any cognitive and memory impairments and associated with hippocampal degenerative changes, include neurodegenerative process and decreased number of living cell. Mitochondrial Diabetes (MD) appears fallowing activation of mutant mitochondrial DNA and is combination of diabetes and cognitive deficit. In this research we showed the correlation...

[ 9 ] - Effect of Trigonelline on Dendritic Morphology in the Hippocampus and Prefrontal Cortex in Streptozotocin-Induced Diabetic Rats

Introduction: Diabetes mellitus causes adverse changes in the neurological morphology of the hippocampus and prefrontal cortex of the brain by increasing oxidative stress. Trigonelline has antihyperglycemic effects and can inhibit oxidative stress. The aim of this study was to evaluate the protective effect of trigonelline on dendritic changes in hippocampal and prefrontal cortex neurons in dia...
