Pem gene is expressed in a time and stage specific manner. Pem transcripts are detectable as early as day 6 in mouse embryonic development, and are abundant in day 7 and 8, but decrease precipitously thereafter. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system. Furthermore, Pem has also shown to be specifically expressed in the proximal cauda and distal corpus regions of the epididymis, the regions where spermatozoa gain forward motility and fertilization competence.

Pem基因的表达具有明显的时间和空间特异性:在鼠胚发育的第6天,即可检测到Pem转录本的表达;第7-8天,Pem表达量达到最高,随后迅速减少;Pem基因在成年组织中一般不表达,但可在生殖组织表达;另外,Pem特异地在附睾近侧尾部和远侧的体部中表达,此处是精子获得运动性和受精能力的地方。

objective to evaluate effect of lulongshengjing pill on the treatment of oligospermatisma with insuffi-ciency of kidney.methods 100cases with oligospermatism with insufficiency of kidney were treated by lulongshengjing pill.the therapeutic course was three months.testicular fluid routine was carried on every month.changes of testicular flu-id indexes(includes amount,colliquation time,spermatozoa density and motility rate)and procreation were observed before and after treatment.results the total effective rate was91%;cure of56;significant improvement of19;improvement of16and ineffective of9.testicular fluid indexes were significantly improved after treatment compared with those before treatment(p.01).conclusion lulongshengjing pill was effective on the treatment of oligospermatism with insufficiency of kidney.
