本文对甘草Lx对青霉噻唑(BPO)-蛋白致敏豚鼠和大鼠过敏休克的保护作用及其机理进行了研究。实验证明,Lx对豚鼠和大鼠过敏休克具有保护作用,可降低休克发生率和死亡率。致敏对照缉豚鼠过敏发生率均为100％。死亡率分别为100％和70％,Lx给药组豚鼠和大鼠过敏休克发生率分别为0和15％,死亡率亦分别为0和5％。Lx可抑 In this paper, the protective effect of licorice Lx on allergic shock induced by penicillin (BPO) -induced guinea pig and rat and its mechanism were studied. Experiments show that, Lx guinea pigs and rats with anaphylactic shock has a protective effect, can reduce the incidence of shock and mortality. Allergic control guinea pigs allergic to the incidence of 100%. The mortality rate was 100% and 70% respectively. The incidence of anaphylactic shock in guinea pigs and rats in Lx group was 0 and 15%, respectively, and the mortality rate was 0 and 5% respectively. Lx can be suppressed
