Objective:observe the effect of Shunbi Yin,a prescription of Activating Blood Circulation and Dipelling Stasis Therapy,on the expression of bFGF in the prostate tissue of prostatic hyperplasia rats.Methods:Model rats of prostatic hyperplasia were created by testosterone hypodermally injected in rats.Observed the epithelia cell height,wet weight of prostate,expression of bFGF in prostate tissue.Results:the hyperplasia of epithelium and interstitium were decreased in model rats of Shunbi Yin group than other groups,and the average positive cell count were significantly lower in the prostate tissue of Shunbi Yin group rats(P0.01).Conclusion:Activating Blood Circulation and Dipelling Stasis Therapy can effect hyperplasic prostate through regulating the bFGF.
