查询词典 ischemic

There was an obvious increase of insulin receptor gene and protein in the cerebral ischemia reperfusion tissues in rats. The positive cells such as neuron, neuroglia cells, vascular endothelium cells possibly participated in regulating the processes of energy metabolism of cells and neovascularization. It implied that the high expressions of insulin receptors in vascular endothelium cells in ischemic zones possibly participated in regulating the pathophysiological changes of the blood vessels in ischemic zones; The higher expressions of insulin receptors in different cells were possibly one of the self-protective machanisms in which the ischemic tissues confront the anoxemia injury.
