[The relationship between postmortem degradation of marrow DNA in bosom bone and late postmortem interval estimation].
OBJECTIVE
To study the relationship between degradation of marrow DNA and late postmortem interval (PMI).


METHODS
Marrow were left on natural condition for 0,1,3,5,7 day after death respectively, Marrow DNA were detected by using Feulgen staining and computerized image analysis.


RESULTS
The content of marrow DNA could be detected till 7 days after death yet.


CONCLUSIONS
The degradation of marrow DNA may be used on estimation the late PMI.
