BACKGROUND AND PURPOSE Mitochondrial dysfunction has been implicated in the cell death observed after cerebral ischemia, and several mechanisms for this dysfunction have been proposed. Reperfusion after transient cerebral ischemia may cause continued and even more severe damage to the brain. Many lines of evidence have shown that mitochondria suffer severe(More)
This experiment was designed to explore the pathogenesis in hypoxic-ischemic encephalopathy (HIE). Sixteen newborn pigs were divided into two groups: (Group A) normal control and (Group B) HIE 24 hours. The glutamate receptor (Glu R) in forebrain crude synaptic membrane (SPM) and free Ca2+i in RBC were tested respectively. The results revealed that the(More)
In order to probe into dexamethasone's effect on glutamate receptor (Glu R) in hypoxic-ischemic encephalopathy (HIE) of newborn, we established newborn pigs' model of HIE to investigate Glu R in their forebrain crude synaptic membrane and the effect of dexamethasone in different HIE times and different dosages on the changes of Glu R. This study included(More)
