Abstract:
Objective To explore the elimination effect of radix Pulsatillae extracts on R plasmid of pseudomonas aeruginosa.Methods R plasmids of pseudomonas aeruginosa were isolated from the sputum of elderly patients suffering from respiratory infection,and the elimination test of radix Pulsatillae extracts on these plasmids was performed in vitro and in vivo.Results Being treated with the extracts for 24,48 and 72 h in vitro,the elimination rate of R plasmids was 0,1.8 %and 3.4 %respectively,while in SDS(sodium dode canesulphonate)control group the elimination rate was 0,0.8 %and 1.6 %respectively.Being treated with the extracts for 24,48 and 72 h in vivo,the elimination rate was 0,2 %and 12.8 %respectively,and 0 in the control group.Conclusions Both in vitro and in vivo,radix Pulsatillae extracts have an elimination effect on R plasmid of pseudomonas aeruginosa,and the effect in vivo is stronger than that in vitro.
