Influence of traditional Chinese medicinal herbs on proliferation and apoptosis of prostatic cells in mice / 中华泌尿外科杂志

ABSTRACT

Objective To investigate the therapeutic effects of traditional Chinese medicinal herbs(TCMH) on benign prostate hyperplasia(BPH) and their influence on proliferation and apoptosis of prostate cells in experimental mice. Methods A total of 120 male Kunming mice(weight,30 to 40 g)were randomly divided into 5 groups:①normal control group;②hyperplastic group;③normal saline(NS)(negative control)group;④TCMH group;⑤finasteride (positive control) group.Each group included 24 mice.The mice in normal control group were killed and their prostates were weighed.The BPH model was induced by implanting the urogenital sinus in the mice in other 4 groups.In the 61st day,the prostate weight of the mice in hyperplastic group was examined after they were killed;and the mice in the remaining groups were fed with NS,TCMH and finasteride,respectively.In the 91st day,the mice in these 3 groups were killed and their prostates were weighed.The proliferation and apoptosis of the prostate cells of mice in the 3 groups were determined by flow cytometry(FCM). Results The prostates in hyperplastic group [(149.30?8.46)mg] were heavier than those in TCMH group [(85.60?17.97)mg] ( P 0.05). Conclusions The TCMH has a significant therapeutic effects on experimental mice with BPH.The mechanisms may be as follows:TCMH can regulate the relevant genes of the prostate cells so that they can promote the apoptosis of the prostate cells and as a result,the volume and weight of the prostate of the mice are reduced.
