Objective To investigate the applicability of the K~+ concentration in aqueous humor to estimate postmortem interval(PMI).Methods 30 White New-Zealand rabbit were sacrificed by air embolism and divided into 10 groups.Aqueous humor and vitreous humor were sampled at 0.5h,1h,3h,6h,8h,12h,16h,20h,and 24h after death.The concentration of potassium,sodium and calcium were analyzed by an autoanalyzer and the data were statistically processed by SPSS software for Windows.Results Increase in potassiam concentration in aqueous humor was correlated with the postmortem interval(R~2=0.956).Conclusion Measurement of potassium concentration in aqueous humor may be used for PMI estimation.
