title: [Ultrastructure changes of electrical injury in rats].
abstract: OBJECTIVE
  To observe ultrastructure changes of electrical injury in rats.
  
  
  METHODS
  An experimental model of rats suffered from the low voltage were designed. Ultrastructure changes of electrical injured tissues were observed under transmission electron microscope.
  
  
  RESULTS
  (1) Plasma of epithelium was concreted in the affected areas and inner membrane system was broken. (2) Hypercontraction bands were observed in skeleton muscles. (3) There was dissolved necrosis and hypercontraction bands in the myocardium. (4) Vacuoles were found in plasma of endothelium of blood vessels on electrical current path, and myelin sheath of nerve fiber were loosed.
  
  
  CONCLUSIONS
  The above mentioned ultrastructure changes could be used as assistant diagnostic index of electrocution. The mechanism of the changes were discussed.
