Bcl-2 positive signals had no obviously changes in cryptorchid testis on 3d, but fluorescent signals of Bcl-2 protein decreased obviously in cryptorchid testis on 6-15d with the germ cell apoptosis increased.

随着隐睾诱导生精细胞凋亡增加，Bcl-2蛋白的表达明显下降，呈下调趋势；而Bax蛋白的表达明显增加，呈上调趋势，尤以精母细胞胞质更为显著。

Results Some spermatocytes all in model and clomiphere groups were denatured or death and spermatid did not develop.

结果：实验对照组的曲细精管上皮中多数精母细胞变性、死亡，精子细胞不发育，无精子形成，管腔中无精子，支持细胞有明显病变。

In male, the immunopositive reaction in spermatogonia, spermatocyte and spermatid to testosterone antibodies strengthened gradually during the development and maturation of testis.

在大生长期和成熟期，精原细胞和精母细胞对孕酮抗体发生强的免疫阳性反应。

Spermatogenesis was disturbed by high-energy shock wave,in which the formation and differentiation of primary spermatocyte were inhibited.

高能冲击波对生精过程的作用可能是抑制初级精母细胞的形成和分化；多次高能冲击波冲击有诱导睾丸细胞凋亡数量增加的趋势。

These results indicated that CB is necessary for synchronization in spindle formation in both oocyte and primary spermatocyte, and that synchronization may be required for subsequent embryo development.

这一结果表明CB的处理可以使精母细胞与卵母细胞同步形成MI纺锤体，使其发育同步，这可能对以后胚胎的发育具有重要作用。

They were expressed abundantly in the spermatogonia cells but decreased markedly when the cell grew into the meiotic spermatocyte stage.

它们在睾丸精原细胞中有高表达，但到精母细胞进入减数分裂时则mRNA水平迅速降低。

Previous studies have demonstrated that primary spermatocyte can undergo meiotic divisions in MI oocytes and the resulting embryos can develop to term. However, the success rate is very poor.

已经证明初级精母细胞在显微融入MI卵母细胞后可以完成减数分裂并且产生的胚胎可以发育到期，只是发育率还非常低，作为一种形式的核移植，细胞周期的同步化处理对于胚胎的发育具有重要意义。

Immunohistochemistry for Bax: Bax expression was detected in germ cell cytoplasm cytoplasm and nucleus of seminiferous tubule theca cell, obviously spermatocyte.

免疫组化观察Bax的表达情况：Bax表达见于生精细胞的胞质和胞核，以精母细胞为主。

Sinensis could be divided into 5 stages, includi ng t he spermospore proliferation stage, the primary spermatocyte stage, the secondar y spermatocyte stage, the spermateliosis stage and the spermiotiliosis stage.

在整个精子发生过程中，N-乙酰半乳糖复合物出现于精原细胞期，并于精母细胞期发生明显的修饰和变化，精子形成期和成熟期没有N-乙酰半乳糖复合物的表达。

In male, three kinds of sex steroid receptors were distributed in the spermatogonia, spermatocytes and spermatids, and the positive reaction was localized in the cytoplasm and nucleus of these spermatogenic cells.

在雄性，3种类固醇激素受体分布在不同发育时期的精原细胞、精母细胞和精子细胞中，受体阳性物定位在胞质和核。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
