Introduction: Brain injury induces an almost immediate response from glial cells, especially astrocytes. Activation of astrocytes leads to the production of inflammatory cytokines and reactive oxygen species that may result in secondary neuronal damage. Melatonin is an anti-inflammatory and antioxidant agent, and it has been reported to exert neuroprotection through the prevention of neuronal d...
introduction: in iran, thousands of young individuals become victims of head injury annually. head injury can damage neuronal cells which may in turn complicate the recovery of the patients. also, the increase of iron in cerebrospinal fluid (csf) following head injury may contribute to the hypoxic-ischemia brain damage by catalyzing the formation of free radicals (harber-weiss rection). the obj...

Also, the increase of iron in cerebrospinal fluid (CSF) following head injury may contribute to the hypoxic-ischemia brain damage by catalyzing the formation of free radicals (Harber-Weiss Rection).

Objective(s): To reach an evidence-based knowledge in the context of the temporal-spatial pattern of neuronal death and find appropriate time of intervention in order to preserve spared neurons and promote regeneration after traumatic spinal cord injury (TSCI). Materials and Methods: The study design was based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-guided...
traumatic brain injury (tbi) is one of the major causes of severe disability and death in the entire world that accidents are mentioned as main factors of it. tbi lead to primary and secondary injuries. primary injuries are created immediately after accidents or bleeding but the secondary injuries are created by complicated process of cellular and molecular responses following primary injury a...
Introduction: Injuries of the peripheral nerve system affect the neurons cell body leading to axon injury. Cannabis sativa plant has anti oxidant and anti apoptotic effects. Therefore the aim of present study was to study the neuroprotective effect of alcoholic extract of cannabis sativa leaves on neuronal density of alpha motoneurons in spinal cord after sciatic nerve injury in rats. Methods:...
objective(s): the alteration of glucose transporters is closely related with the pathogenesis of brain edema. we compared neuronal damage/death in the hippocampus between adult and young gerbils following transient cerebral ischemia/reperfusion and changes of glucose transporter-1(glut-1)-immunoreactive microvessels in their ischemic hippocampal ca1 region. materials and methods: transient cere...
multiple sclerosis (ms) is a chronic inflammatory demyelinating disease of the central nervous system that inflammation, demyelination, oligodendrocyte loss, gliosis, axonal injury and neurodegeneration are the main histopathological hallmarks of the disease. although ms was classically thought as a demyelinating disease, but axonal injury occurs commonly in acute inflammatory lesions. in ms mi...
