Concentration changes of electrolytes in vitreous humor of acidosis associated with different postmortem interval in rabbits / 重庆医科大学学报

ABSTRACT

Objective:To investigate the chemical composition changes in vitreous humor of rabbits at different times after the death of acute acidosis. Methods: 30% Sodium Dihydrogen Phosphate were used in rabbits to induce the animal model of acute acidosis,and we observed the ionic concentration changes in vitreous humor at different times. Results:72 hours after the death of acute acidosis,the concentration of Potassium,Magnesium,Phosphorus in vitreous humor were gradually increased and Calcium were decreased gradually with the time of death. Sodium performance instability,the change of chlorinity firstly decreased and then increased.Potassium ions was closely related to death time (R2=0.976 1). Conclusion:After the death of acute acidosis,the concentration of Potassium in the vitreous humor of rabbits can be used to infer PMI in the death of acute acidosis.
