摘要 目的:探讨可溶性白细胞分化抗原40配体(sCD40L)和一氧化氮合酶(NOS)活性对高脂血症大鼠阴茎勃起功能的影响。方法:用高脂饮食(HFD)诱导Wistar雄性大鼠,将30只大鼠分为正常饮食A组及高脂对照B组;造模成功后在第2周和第4周末,取阴茎海绵体,采用免疫组化方法观察对照A、B组大鼠阴茎海绵体内sCD40L,使用酶联免疫吸附试验测定大鼠阴茎组织中sCD40L含量,使用分光光度法测量NOS活性。结果:第4周高脂血症组sCD40L的含量明显高于第2周,NOS活性浓度及阴茎勃起次数均明显低于第2周,差异具有统计学意义(P<0.05)。结论:高脂血症中sCD40L的升高进而引起一系列炎症反应,内皮细胞功能障碍,导致NOS活性降低引起勃起功能障碍(ED)。
