Abstract:
OBJECTIVE:To investigate the correlation between postmortem interval (PMI) and the changes of electrical conductivity in vitreous humor in rabbits after death.
METHODS:The changes of electrical conductivity in vitreous humor in rabbits were measured using the conductivity meter under 30 degrees C during 0-48 hours and 20 degrees C during 0-120 hours after death.
RESULTS:Electrical conductivity in vitreous humor in rabbits increased gradually under 30 degrees C and 20 degrees C from 0 to 48 hours and from 0-120 hours after death. The formulae of the relationship between PMI and conductivity under 30 degrees C and 20 degrees C were obtained by statistical analysis and the correlation coefficients were 0.970 and 0.983 (both P < 0.01), respectively.
CONCLUSION:The increase of electrical conductivity in vitreous humor in rabbits after death may be used as the relatively objective parameter for PMI estimation.
