摘要
应用ＲＴ－ＰＣＲ方法测定大鼠阴茎组织中ＮＯＳｍＲＮＡ的含量。结果显示，大鼠阴茎组织中存在ＮＯＳｍＲＮＡ表达，其表达程度约为小脑的３０％。老龄大鼠与２月龄大鼠相比阴茎组织中ＮＯＳｍＲ－ＮＡ表达水平显著降低，提示阴茎组织中ＮＯＳｍＲＮＡ表达下降可能是阳萎年龄依赖性的原因之一。
NOS mRNA in penile tissue of rats have been detected by quantitative PCR and was found to be about 30% of the expression level present in cerebellum. NOS mRNA in penile tissue of older rats was markedly decreased as compared with that in younger rats. The lower expression level of NOS mRNA in penile tissue might be relevant to the age-dependent impotence.
