摘要 目的:探讨前列腺组织慢性缺血与前列腺增生(BPH)的关系。方法:选用雄性SD大鼠40只,随机分为实验组(用血管银夹套夹双侧髂总动脉建立大鼠前列腺缺血模型)和对照组(腹部切开分离髂总动脉,但不缩窄),每组各20只。术后饲养4周,称重,处死,取前列腺称重,并用ELISA法定量检测前列腺组织碱性成纤维细胞生长因子(bFGF)和缺氧诱导因子(HIF)-1α蛋白的表达。结果:两组术后死亡率及实验终点大鼠体质量无统计学意义。实验组前列腺湿重与指数均明显高于对照组(P<0.05)。实验组前列腺组织中bFGF和HIF-1α蛋白表达显著高于对照组(P<0.05),且bFGF蛋白浓度与前列腺湿重成一定线性相关(R2=0.91)。结论:慢性缺血是引起BPH的机制之一。
