Abstract:
OBJECTIVE:To study the relationship between the postmortem interval (PMI) and the changes of DNA content in rabbit's cornea epithelial and endothelium.
METHODS:Using the computerized image analysis to measure the DNA content in the cornea epithelial and endothelium of 105 rabbit's at every six hours during 72 hours after death.
RESULTS:The degradation rate of DNA in nuclear has an apparent relationship in 72 hours after death of the rabbits.
CONCLUSION:The determination of the quantity of DNA in cornea nuclear is a new method to estimate the PMI accurately.
