通过定量检测大鼠去势前后肾上腺和前列腺中Cypl7al基因的表达，试图从分子水平解释去势手术后大鼠机体内雄性激素水平的变化。

英文摘要：

In this paper the change law of Cypl7al gene expression in the process was studied, in which the rats＇ adrenal secretes androgen after orehiectomy. The Cypl7al gene expression in adrenal and prostate tissues was detected via real-time fluorescent quantitative PCR on different time points, which were before orehiectomy and 1 week, 2 weeks, 3 weeks, 4 weeks after orchiectomy, respectively. The results indicate that Cypl7al gene expression in adrenal would increase after orchiectomy, and reach the maximum when 3 weeks after. That Cypl7al gene exists in rat＇s prostate tissue was discovered for the first time. The conclusion is that adrenal have the function of compensation, increasing the secretion of androgen after orchiectomy. It is presumed that prostatecan synthesizes DHEA as well.
