Objective: To study the effect of Qianlieshu Capsule on bacterial prostatitis in rat. Method: The animal model of bacterial prostatitis was established by injection of Escherichia coli in ventral prostates

and Qianlieshu was given in different dosages for 10 days. The count of white blood cell

the density of lecithin

and bacteria colonies in prostatitis liquid

while the prostate weight

index

and pathological changes were observed. Result: Qianlieshu Capsule could obviously decrease white blood cells(P<0.01) and bacteria colonies(P<0.01)

and increased lecithin(P<0.05) were only found for the high dosage

deduced prostate weight

index were observed in the middle and high dosages. The pathological of inflammmator changes were obviously inhibited in high dosage(P<0.05). Conclusion: Qianlieshu Capsule has significant anti- bacterial prostatitis actions.
