Dynamic Posturography of Injured Lower Limb in Postural Evoked Response / 法医学杂志

OBJECTIVE@#To analyze the balance function of injured lower limb by dynamic posturography.@*METHODS@#Using the dynamic posturography instrument, the postural evoked responses of sixty-two normal people and two hundred and fifty-eight people with injured lower limb bones and joints were detected. The test was included sensory organization test (SOT) and adaption test (ADT). The results of two groups were compared by t test.@*RESULTS@#Compared with the normal people, the impaired people had significant statistical differences in balance scores of SOT3-SOT6 and proportion score of dynamic proprioception (P < 0.05). There was no obvious decrease in ADT.@*CONCLUSION@#The balance function of injured lower limb significantly decreases.

Concentration changes of amylase in vitreous humor of acute pancreatitis associated with different postmortem interval in rabbits / 法医学杂志

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.
