title: [The development and changes of pressure of putrefactive gas in cadaveric enterocelia in spring and its forensic application].
abstract: OBJECTIVE
  To study the development and changes of pressure of putrefactive gas (PPG) in cadaveric enterocelia in spring, and to explore its application in estimation of postmortem interval (EPI).
  
  
  METHODS
  57 goats were divided into 2 groups according to means of death, on land or in water. Celiac PPG were observed timely and systematically.
  
  
  RESULTS
  The development of PPG in cadaveric enterocelia, which can be divided into raising phase, peak phase, and declining phase was observed, and a model to estimate postmortern interval by changes of PPG was founded.
  
  
  CONCLUSIONS
  Measuring PPG in cadaveric enterocelia could be used in forensic EPI.
