Aim. To study the effect and mechanism of traditional Chinese medicine Qinbai Qingfei concentrated pellet (QQCP) against Mycoplasma pneumoniae (MP). Methods. Rat airway smooth muscle (ASM) cells were used to examine the antimycoplasmal activity of QQCP via four drug-adding modes: pre- and postadding drugs, simultaneous-adding after drug and MP mixed, and simultaneous-adding drug and MP; taking roxithromycin dispersive tablets (RDT) as positive control, the cellular A570 values were determined by MTT method. Results. All of A570 values in QQCP group were significantly higher than those of the corresponding MP control group in four drug-adding modes; there was no significant difference in A570 values between the QQCP group and that of the positive control group , confirming that QQCP could significantly inhibit the infectivity of MP to ASM cells. Conclusion. QQCP had significant activity in preventing and treating MP infection, killing MP, and antiabsorption.
