An experiment pathologic study of crush injury—crush syndrome

To study the pathological process and renal patho morphology of crush syndromed.The rabbit model of crush injury crush syndrome was established.Transmission electron microscopy(TEM),biochemistry,radioimmunoassay and immuohistochemistry were employed.The results demonstrated that the serum K + and BUN increased,The serum CO 2CP decreased after crush injury.The degeneration and necrosis of the epithelial cells of the renal tubule and myoglobin casts in the renal tubules were observed in crush syndrome,the serum K + increase was absent.Our results may be regarded as criteria for the diagnosis of the crush injury crush syndrome.The serum K + increase was the cause of death in early stage after crush injury.
