Abstract: Objective To explore the changes of serum IgE and tryptase caused by anaphylactic shock rats and discuss the relation to PMI and preservative environm ent of corpse and specim en. Methods Rats were used for establishing anaphylactic shock m odels and random ly divided into room tem perature group, refrigeration group, frozen group, manual hem olysis group, specim en preservation group. And the control group was also established. The blood sam ples were collected after rats were sacrificed. The de-gree of hem olysis was graded according to the color of the upper layer of the serum . The mass concen-tration of IgE and tryptase in each group was detected by ELISA. Results The levels of serum IgE and tryptase in anaphylactic shock dead rats were higher than that of the control group. Room tem perature and frozen m ade obviously differences on the levels of serum IgE and tryptase with various PMI. The levels of serum IgE and tryptase in refrigeration group show ed relatively stable. The levels of serum tryptase and IgE were elevated with differently increasing hem olysis. The levels of serum IgE and tryptase show ed no obvious changes during the specim en kept under different tem perature conditions for 25 days. Conclusion Serum IgE and tryptase obviously increased in anaphylactic shock rats. H ow ever, the levels were influenced by PMI and environm ental tem perature, especially under the conditions of room tem perature and frozen.
