Results: Primary mediastinal seminoma was prone to occurring in the young with non-specific manifestations.

With western blot analysis and DNA polymerase chain reaction-single strand conformation polymorphism assay,protein product of Rb gene and mutation in exon 5～8 of P_(53) gene were examined in 17 cases of human testicular seminoma.

采用Western印迹和DNA聚合酶链反应－单股构造多态性分析法对17例人睾丸精原细胞瘤组织标本的抗癌基因Rb表达的蛋白产物和P_（53）基因外显子5～8的突变进行检测，发现有3例标本的Rb基因表达的蛋白产物缺失，有4例标本的P_（53）基因有点突变，对照的正常人睾丸组织和视网膜组织均呈Rb基因蛋白产物表达阳性，对照的正常人睾丸组织中未发现P_（53）基因突变。

Note the lymphoid stroma between the nests of seminoma.

The result show: The strong positive reaction on the plasma membrane of type Aspermatogonia and the head of maturing sperm, and a lesser positive reaction on the plasma membrane round spermatid.

结果表明：(1)在A型精原细胞的质膜和成熟的精子头部有强阳性反应，早期精子细胞质膜有较强的阳性反应。

In fact, it is very early, they have to travel to the beginning of the development of puberty, when stored in the scrotum spermatogonium only slowly into mature sperm, is still dormant, dormant fabulous.

其实，早的很呢，他们要到青春期开始发育的时候，阴囊里储存的精原细胞才会慢慢转化为成熟的精子，现在还在休眠、蛰伏着呢。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
