类胰蛋白酶与过敏性休克死亡的法医学鉴定

目的探讨类胰蛋白酶与过敏性休克的关系。方法从类胰蛋白酶的生物学特性、正常人分布、检测方法及其与过敏性休克的关系,并应用ELISA方法检测三例尸体血清类胰蛋白酶的浓度,对三例过敏性休克死亡的案例作回顾性分析。结果两例血清中类胰蛋白酶的含量分别为52ng/ml和121ng/ml(高于正常值10倍以上),另一例浓度为0.73ng/ml。结论诊断过敏性休克,类胰蛋白酶含量的检测是很有意义的,但不能单凭检测结果下结论。

Tryptase and fatal anaphylaxic reaction

OBJECTIVE: To investigate the relationship between tryptase in serum and anaphylaxis. METHODS: The concentrations of tryptase in the sera of heart blood in three persons died from anaphylaxis shock were detected by ELISA. The first sample was obtained from a man, aged 38, died of injecting Amikacin. The second sample was obtained from a man, aged 42, died of injecting Cephradine. The third sample was from a woman, aged 39, died of injecting Lincomycin. All samples were stored in -20 degrees C. RESULTS: The concentrations of tryptase in sera were 52 ng/ml, 121 ng/ml and 0.73 ng/ml. It was unknown why the concentration of tryptase in the third sample was normal. CONCLUTION: In fetal anaphylaxia reaction tryptase measurement is a useful indicator, but the diagnosis is not to be based on the test alone.
