introduction: according to previous studies, colchicine causes neuronal destruction and learning depression. in this project, effects of colchicine injection into the ca1 and interaction between colchicine and nitric oxide (no) in this area on the expression of drug-seeking behavior were investigated. methods: wistar rats (250-300 g) were bilaterally cannulated at the ca1 area. colchicine (2-8 ...
Abstract* Introduction: Chronic morphine exposure can cause addiction and affect synaptic plasticity, but the underlying neural mechanisms of this phenomenon remain unknown. Herein we used electrophysiologic approaches in hippocampal CA1 area to examine the effect of chronic morphine administration on short-term plasticity. Methods: Experiments were carried out on hippocampal slices taken f...
Background: A human immunodeficiency virus type 1 (HIV-1)-based lentiviral vector (LV) pseudotyped by a variant of rabies envelope glycoprotein, FUG-B2, has previously been prepared and used in transfection of hippocampal CA1 ("Cornu Ammonis" area 1) neurons. This study aimed to verify reactive gliosis and neuronal damage after injection of the vector into the rat hippocampus. Methods: HEK 293T...
BACKGROUND GABAergic interneurons in the hippocampal CA1 area are mutually communicated by gap junctions (GJs) composed of connexin36 (Cx36). We examined the role of Cx36 in CA1 in manifestation of kindled seizures and hippocampal kindling in rats. METHODS Quinine, as the specific blocker of Cx36, was injected into CA1, and kindled seizures severity was examined 10 min afterward. Moreover, qu...
Introduction: Recent findings revealed the biological effects of iron oxide nanoparticles on the central nervous system. Moreover, the brain cholinergic system plays a role in the modulation of anxiety behaviors. Therefore, this study aimed to evaluate the role of dorsal hippocampal muscarinic cholinergic receptors of the CA1 area on anxiety induced by iron oxide nanoparticles in adult male rat...
Background Acute and chronic effects of nitric oxide on oxidative stress and neuronal demyelination have been reported in human and animal models. Objective Oxidative stress is involved in the pathogenesis of demyelinated animals; thus, this study investigated the effects of nitric oxide system and ethidium bromide on oxidative stress in the hippocampal formation. Methods This experimental...
Background and Objectives: Study of deleterious effect of neurotoxins on the animals' brain is a fascinating research plan. In this project, the damage effect of colchicine on the hippocampal cornu ammonis 1 (CA1) was examined by the studying the hippocampal tissue. Materials and Methods: Injections of colchicine (1-75 μg/rat, intra- hippocampal CA1) were performed in cannulated male Wistar rat...
