ABSTRACT
The detection of drug-induced anaphylactoid reactions remains a global challenge,still lacking mature and reliable animal models or test methods. Therefore,the purpose of this paper is to explore and establish the test methods and evaluation standards for anaphylactoid reactions that apply to injection drugs. Based on the anaphylactoid reaction symptoms of mice induced by intravenous injection drugs C48/40 and Tween 80,a list of systemic anaphylactoid reaction symptoms in mice was sorted out and an evaluation standard of anaphylactoid reactions symptoms was established by applying symptom intensity coefficient K( that can represent these verity of anaphylactoid reaction symptoms) and its calculation formula Accordingly,histamine,tryptase,and Ig E were selected as blood indicators of anaphylactoid reactions,so that a test method combining symptoms evaluation and blood makers detection was established.This test method could be used to evaluate the characteristics of anaphylactoid reactions: coefficient K,blood histamine levels were highly and positively correlated with C48/80 and Tween 80 dose; The log value of histamine was highly and positively correlated with K; tryptase level may rise,or remain steady,or drop,possibly associated with the characteristics of the tested object and time for blood taking; and Ig E level would drop or remain steady,but it would not rise,which can be clearly distinguished from type I allergic reactions. On this basis,tiohexol,iopromide,paclitaxel,Xuesaitong Injection,Shuanghuanglian Injection and Shengmai Injection were used to investigate the applicability. The testing results showed a high degree of consistency with the actual clinical situation. The results suggest that the method of systemic anaphylaxis test in mice has high sensitivity,specificity and good consistency with clinical practice.It is suggested to be further validated and popularized.
