Objective To observe the effect of Kechuanning(KCN) on regulating the level of EOS in asthma guinea pigs and study the mechanism of prevention and treatment.Methods The pig models were induced by aerosolized ovalbvmin,and compared with dexamethasone,the effects of KCN were measured on changes of EOS in serum and in bronchoalveolar lavage(BALF).Results The contents of EOS in serum and BALF were marked decreased compared with MG(P〈0.05),and dexamethasone was more effective to decrease the serum EOS than KCN was,but there was no significant(P﹥0.05).Con...
