Abstract:
Objective: Though especially efficient for cardiovascular and cerebrovascular diseases treatment, many serious anaphylactic diseases could be induced by Ciwujia Injection (CWJI). However, study of the mechanism and detection of allergies have been investigated by the unknown sources of allergenic substances. In this study, a guinea pig model which could mimic the symptoms of anaphylactic reactions induced by Ciwujia Injection (CWJI) was modeled and used to screen the allergenic substance of CWJI. Methods: Guinea pigs were sensitized three times every other day with CWJI and excitated 14 d after the last sensitization administration. Then, the histamine, trypsin, IL-4 and IFN-γ levels, the Annexin V positive rate of peritoneal mast cells (PMC) were detected, the numbers of B lymphocyte and the pathological changes were also analyzed to verify the guinea pig allergy model, PCA test and IgE antibody levels were determined to study the mechanism. Results: The levels of total IgE, histamine, and trypsin were significantly increased after CWJI sensitization, IL-4 level was elevated, Annexin V positive of PMC cell rate, local skin reactions, and declined IFN-γ were observed after excitation. Histological examination showed that mild pathological changes in lungs were found. Conclusion: This guinea pig model may provide a powerful tool to study the mechanism in CWJI induced anaphylaxis and screen the allergic source of CWJI.
