[Relationship between DNA degradation and postmortem interval of corrupt corpse].

Abstract

OBJECTIVE:

To study the relationship between DNA degradation and postmortem interval of corrupt corpse.

METHODS:

By determining the marrow DNA content with histochemical technique and image analysis.

RESULTS:

The content of marrow DNA decreased gradually with prolongation of postmortem interval, and it evencould be detected till 14 days after death.

CONCLUSION:

There was a linear relationship between the degradation rate of the nuclear DNA and postmortem interval.
