摘要 目的通过检测睾酮合成过程中3个关键酶的活性,探讨邻苯二甲酸二丁酯影响雄性仔鼠生殖器官发育的作用机制.方法取8周龄Sprague-Dawley(SD)大鼠,随机分为对照组和染毒组(邻苯二甲酸二丁酯组,即DBP组).于怀孕第13-21天,对照组按照1mL/只灌服花生油,DBP组按照500mg/kg灌服邻苯二甲酸二丁酯(DBP).分娩后观察有无尿道下裂畸形.于仔鼠出生后第4、15、25及90天,抽取外周静脉血,检测睾酮水平;解剖、记录性腺位置及发育情况,取出性腺,采用免疫组织化学方法检测3β-HSD、P450c17及P450scc的表达.结果 DBP组产雄性仔鼠88只,其中隐睾17只,尿道下裂7只,对照组未发现隐睾及尿道下裂雄性仔鼠;对照组出生后第15、25及90天血浆睾酮水平明显高于DBP组同期水平,P<0.05.DBP组间质细胞3β-HSD、P450c17及P450scc的表达明显低于对照组,P<0.05.结论 DBP通过降低睾酮合成过程中关键酶的活性,减少睾酮的合成,进而影响雄性仔鼠生殖器官的发育.
