Ischemic Brain Injury Zinc

As such, zinc, which is able to function both as a signaling mediator and neurotoxin, has been implicated in cerebral ischemia. While zinc was first purported to have a role in cerebral ischemia nearly twenty years ago, our understanding of how zinc mediates ischemic injury is still in its relative infancy.

Hypoxic-ischemic brain injury most often results from insults such as cardiac arrest, vascular catastrophe, poisoning (such as carbon monoxide intoxication or drug overdose), or head trauma. While many patients expire without recovering awareness, improved techniques in resuscitation and artificial…

Removing zinc may be an effective and novel approach to reduce ischemic brain injury. Introduction Zinc (Zn 2+ ) is the second most abundant transition metal in the human body.

Here we reported that CDK5-Tyr15 phosphorylation by zinc induced CDK5 activation in brain ischemic injury. CDK5 activation and CDK5-Tyr15 phosphorylation were observed in the hippocampus of the rats …

In the present study, the effect of zinc in ischemic brain injury was examined in an embolic model of stroke in rats. Furthermore, the effect of zinc in combination with bicuculline, a GABAa antagonist, was also examined in the ischemic injury.

Ischemia-induced high accumulation of intracellular zinc significantly contributed to ischemic brain damage through promotion of neuronal apoptotic death. Removing zinc may be an effective and novel approach to reduce ischemic brain injury.

What Is Tbi In Medical Terms TBI is the nation’s leading third-party technology distributor. The VA requires a physiatrist, psychiatrist, neurosurgeon or neurologist to conduct initial TBI exams. Less commonly, some are using hyperbaric oxygen to treat TBI," Henderson says.

In addition, brain ischemia was shown to result in neuronal cell death through necrosis and apoptosis [18], which are processes that require atp [35] Many research groups have determined that zinc-induced neuronal death is one neurotoxic mechanism that underlies ischemic brain injury [10…

Apr 23, 2007  · CHANGES IN ZINC LEVELS DURING ISCHEMIA. Similarly, Kitamura and colleagues ( 37) also found that extra-cellular zinc levels in the focal ischemic cortex increased within 15 min, peaked to twice the basal level (~300 nM) within 30 min post-ischemia, and returned to basal level within 15 min after reperfusion.

Although both zinc and ROS have been shown to contribute to brain injury after ischemia, the present study provides the first direct evidence that zinc increases ROS while ROS increases zinc, a zinc-ROS-zinc positive feedback loop to amplify the damaging effect of both, thus causing greater damage to the brain.

Background and Purpose- Although intracellular zinc accumulation has been shown to contribute to neuronal death after cerebral ischemia, the mechanism by which zinc keeps on accumulating to cause severe brain damage remains unclear.
