Study on the relationship between postmortem interval and the change of absorbance in vitreous humor of rabbit after death

Abstract

Abstract: Objective To seek a exact method of estimating Postmortem interval (PMI). Methods This study was preformed to investigate the relationship between postmortem interval and absorbance in vitreous humor of rabbit after death.The absorbance in vitreous humor of 48 rabbits after death were investigated with Model 754 spetrophotometer in apt wavelength (420nm).Results There exists positive linear regression association between postmortem interval (Y ) and absorbance in vitreous humor (X )(r=0.983 27, P< 0.05 ),during rabbits after death 0 to 72 hours.The formula of linear regression is Y=453.30X＋ 0.75(Y=postmortem interval=PMI,X=absorbance in vitreous humor).Conclusion The absorbance in vitreous humor can be as reference indicator to estimate PMI within hour 72 .

Key words: postmortem interval, absorbance, vitreous humor
