Abstract:
OBJECTIVE:To observe changes of the length of sarcomere of rat when restiffening.
METHODS:We measured the length of sarcomere of quadriceps in 40 rats in different condition by scanning electron microscope.
RESULTS:The length of sarcomere of rigor mortis without destroy is obviously shorter than that of restiffening.
CONCLUSION:The length of sarcomere is negatively correlative to the intensity of rigor mortis. Measuring the length of sarcomere can determine the intensity of rigor mortis and provide evidence for estimation of time since death.
