Objective: To investigate concentration changes of amylase in rabbits vitreous humor of acute pancreatitis associated with postmortem different interval.
Methods: To induce animal model of acute pancreatitis with sodium taurocholate, observed concentration changes of amylase after different postmortem interval, then compared with normal.
Results: The concentration of amylase in vitreous humor of rabbit 24h after death were related to postmortem interval significantly; The concluded formulae of the relationship between postmortem interval and amylase concentration is y=8.7420+0.7699x-0.0083x2 (R2=92.62792, F=14.89734, P=0.001).
Conclusion: Concentration changes of amylase in vitreous humor of acute pancreatitis associated with postmortem interval may provide a new sensitive and objective method for the forensic early injury time estimation.
