Abstract:
OBJECTIVE:To explore the application value of serum total IgE, tryptase and chymase in the identification of death caused by drug anaphylactic shock.
METHODS:The general information from 235 cases of non-drug anaphylactic shock and 32 cases of drug anaphylactic shock were analyzed. The serum IgE level had been detected in the cases. Ten cases caused by coronary disease and 10 cases caused by sudden manhood death syndrome were selected from non-drug anaphylactic shock cases for the control group. Expressions of tryptase and chymase in the lung and heart were detected using immunohistochemistry method. The number and IOD of positive mast cells were counted.
RESULTS:In the drug anaphylactic shock group, the IgE value of 18 samples (56.25%) was significantly higher than the normal upper limit of 120 IU/mL. In the non-drug anaphylactic shock group, the IgE value of 67 samples (28.51%) was higher than 120 IU/mL. The expressions of tryptase and chymase were significantly increased in lung and myocardial tissue in drug anaphylactic shock group (P < 0.05).
CONCLUSION:Tryptase and chymase are more superior than that of the serum total IgE in the diagnosis of death caused by drug anaphylactic shock, and are more suitable in forensic practice.
