Background: The neuron death resulting from traumatic brain injury can be classified into 3 types:(1)neuron death due to primary injury;(2)neuron necrosis due to secondary injury such as hemorrhage, compression, anoxemia and ischemia;(3)neuron apoptosis due to inflammatory factor, cytokine,, excitatory transmitter, Ca~(2+) overload and oxygen radical et al.

RESULTS: After ischemia-reperfusion injury, the rats had hydrouria, urine osmotic pressure depress, symptoms of carnine and urea nitrogen increasing. HE staining demonstrated that renal tubular epithelial cells were swelling, necrosis, and desquamate.
