Pathological study of the skeletal muscle in electrocution / 中国法医学杂志

Demonstration of the abnormal distribution of Mb and Fn in electric injuries of skeletal muscles. The electrocution model of rats was established, and the human autopsy samples of electrocution were collected. Immunohistochemical study of myoglobin(Mb) and fibronectin(Fn) were performed on the skeletal muscles in the electric current pathways. The results showed that the muscle fibers showed the bamboo-like appearance and depletion of the Mb as well as the positive reaction of Fn which was called the python-pattern. This experiment proved that the bamboo-like appearance and python-pattern change of the skeletal muscle fibers have the practical value in the medicolegal diagnosis of electrocution without typical current mark.
