摘  要:目的评价爱普列特对对大鼠前列腺Bcl-2、Bax、CD34、eNOS及5α还原酶mRNA表达的影响。方法分别给予雄性大鼠爱普列特(爱普列特组)、非那雄胺(非那雄胺组)和生理盐水(正常对照组),观察大鼠Bcl-2、Bax、eNOS、微血管密度(MVD)以及2种5a还原酶mRNA的表达情况。结果爱普列特组Bc1—2、eNOS、MVD(148±42、72.3±48.5、4.6±2.2)与非那雄胺组(152±59、144.8±80.8、4.9±1.3)及正常对照组(216±52、293.9±116.0、8.0±3.0)比较,3个指标均下降(F值分别为6.6、0、26.45、9.52、均P〈0.01);Bax在爱普列特组为(390±167)、非那雄胺组为(311±155),较对照组(185±73)上升(F=6.35,P=0.004),三组Srd5α1及Srd5α2还原酶mRNA的表达差异无统计学意义(F值分别为0.427和0.58,均P〉0.05)。结论爱普列特可以促进前列腺细胞凋亡,抑制血管生成,减少微血管密度,但可能不能影响5a还原酶mRNA的表达,且其作用与非那雄胺相似。Objective To identify the effect of epristeride on the expressions of Bcl-2, Bax, CD34, eNOS and 5 alpha-reduetase mRNA in rat prostate. Methods Male rats were fed with epritseride, finasteride or physiological saline, respectively. The expressions of Bcl-2, Bax, CD34, eNOS and 5 alpha-reductase mRNA in the prostate tissue were detected and analyzed. Results The expressions of Bcl-2, eNOS and microvessel density (MVD) were lower in epritseride group (148± 42, 72.3±48. 5 and 4. 6±2. 2) and in finasteride group (152±59, 144.8±80.8 and 4.9±1.3) than in physiological saline group (216±52, 293.9±116.0 and 8.0±3.0, F=6.60, 26.45 and 9.52 respectively, all P〈0.01). The expression of Bax was increased in epritseride group (390± 167) and in finasteride group (311±155) than in physiological saline group (185±73, F=6.35, P=0. 004). There were no significant differences of the expressions of 5 alpha-reductase (type 1 and type 2) mRNA among the three groups (F=0. 427 and 1.58 respectively, both P〉0.05). Conclusions Epristeride may induce apoptosis of prostate cell, inhibit angiogenesis and reduce MVD, but it has no effect on the expressions of 5 alpha reductase (type 1 and type 2) mRNA, being similar with finasteride.
