RESUMO
<p><b>OBJECTIVE</b>To investigate the effect of Qianlie Huichun capsular on Fas expression and cell apoptosis of prostate gland tissue in the model rat.</p><p><b>METHOD</b>Hypertrophy of prostate model rat was established by injecting testosterone to gelding male rats. After being treated with Qianlie Huichun ig 30 days, the rats were killed and prostate glands were resected for examination. The Fas expression was examined by immunobistochemical SABC. The cell apoptosis and the peak of cell apoptosis in the prostate gland of the rats were examined by flow cytometry. Compared with model group, the weight of prostage gland tissue in groups treated with Qianlie Huichun capsular was light (P < 0.01).</p><p><b>RESULT</b>Compared with model group, the Fas expression in all treatment groups increase(P < 0.05, P < 0.01). Compared with normal and model groups, cell apoptosis in all treatment groups increase at different level(P < 0.01).</p><p><b>CONCLUSION</b>The Qianlie Huchun capsular increases the Fas expression and cell apoptosis of model rats, and shows a definite treatment effect on the hypertrophy of prostate by promoting the apoptosis of prostate cell.</p>
