Ultrastructure changes of electrical injury in rats

Abstract

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)Plasm 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 myocardieum. (4)Vacuoles were found in plasm of endothelium of blood vessels on electrical current path, and myelin sheath of nerve fiber were loosed. Conclusion The above mentioned ultrastructure changes could be used as assistant diagnositic index of electrocution. The mechanism of the changes were discussed.

Key words: tissue, electrical injury, ultrastructure
