Abstract:
Pseudoallergic reactions occured after the first administration of patients, and the pathogenic mechanisms of them were different from the allergic reactions which needed excitation after antigen sensitization. To provide a basis for evaluation, clinical use and drug development of pseudoallergic reactions, the models were established by two kinds of Chinese herbal injections (CHI) both on different strain or gender mice. With the use of ICR, Kunming, BALB/C, C57 mice, pseudoallergic tests of two CHI were conducted to compare the sensitivity of four strains mice, and compared the differences in male and female animals. Test substances contain 0.8% Evans blue (EB) were intravenously injected into different strain and gender mice. Scores of ear blue staining and quantitation of ear EB exudation were the parameters for pseudoallergic reaction. Results of strain difference indicated that both CHI A and B could cause severe pseudoallergic reactions indicated by obvious vascular hyperpermeability on ICR mice. The pseudoallergic reactions in ICR mice are more obvious under the the same dose of injection, which stated the sensibility of ICR mice. And the reactions of KM mice and BALB/C mice were slightly reduced which compared to ICR mice, even alomost nothing on C57 mice. Comparison results of gender difference showed that one CHI was not have significant difference in male and female animals, but male animals were more susceptible than females on another CHI. Therefore, ICR mice were preferable experimental strain on the model of pseudoallergic reactions induced by CHI A and B. Because of female animals were easily influenced by estrous cycle, the pseudoallergic reactions induced by CHI A and B select and use male mice befittingly.
