Abstract:
Objective To search some references for estimating the time of death in some murder cases by observation the dynamic changes of organic amines derived from isolated human hepatic tissues. Method The contents of histamines, putrescines, cadaverines and undecomposed amino acids from the isolated human hepatic ussues were assayed dynamically by the method of high performance liquid chromatography (HPLC). Results The contents of the organic amines produced by the putrefaction under 8℃,15℃ , 23℃ and 32℃ were increased along with the time elapsed after death under four environmental temperatures before attaining to their peak value, While the contents of the undecomposed amino acids were decreased gradually after death. Conclusion The amount of organic amines produced by putrefaction of the isolated human hepatic tissues were directly related to the time of death. So do the environmental temperature.
