Cause and mechanism of death from hanging with arms bound of 10 rabbits were studied by blood gas analysis. Resuits indicated ahat remarkable changes of PH, PaO2,PaCO2, HCO3-, BE－B, K+ and Ca2+ occured as compared with those before the experiment. Respiratory arrest was found before heart arrest.
In this paper,We illustrate the vital reaction and its important application to medicolegal necropsy by introducing how to identify and examine the injury of life-time and postmortem injury,death by fire and being burned after dead,drowning and being put into waterafter dead,hanging and being hanged after dead.
The analysis revealed that there were no obvious relationships between the sites of hanging marks,the materials of ropes,the hanging postures and subconjunctival petechiae,which directly related to the degree of blood vessel compression.
