精子发生的

The histological structure shows the lobule testis in Leptobotia elongate Bleeker, and the spermatogenesis is divided into 6 phases based on the size, nucleolus number, the degree of nucleus and cytoplasm condensation.

组织学结构显示长薄鳅的精巢属于小叶型，根据发育过程中细胞的大小、核仁多少、细胞核和细胞质浓缩的程度将精子发生划分为6个时相。

The ovine testicular tissue survived and its volume increased significantly, but it failed to differentiate to reach spermatogenesis.

结果表明，添加CsA组与不添加组的移植试验结果无显著差异；移植入的羊睾丸组织块可在受体动物中存活，体积明显增大，但不能分化以实现精子发生。

Varicocele can result in spermatogenesis disorder, and there is significant correlation with survivin.

survivin的表达与精子发生早期维持细胞的增殖有关。

Recently, 10 novel genes involved in human spermatogenesis were identified by microarray analysis of human testicular tissue.

近年来，通过人类睾丸组织的基因芯片分析鉴定了10个与人类精子发生相关的新基因。

Spermatogenesis is a continuum of cellular differentiation in which three principal phases can be discerned: spermatogonia renewal and proliferation, meiosis and spermiogenesis.

睾丸的精子发生是一个独特复杂的细胞分裂分化过程。

Objective: To explore the expression of survivin in testicular tissue of experimental varicocele rats and its correlation with spermatogenesis.

目的：检测细胞凋亡抑制因子survivin mRNA及survivin蛋白在精索静脉曲张大鼠睾丸组织中的表达，初步探讨其在精子发生过程中的意义。

Spermatogenesis education isthe seminal vesicle for the same spermatocyst, the size of the nucleus is very similar tochromosomal changes, and the developmental level coincide.

拟黑多刺蚁精子发生是以育精囊为单位进行的，同一育精囊的生精细胞形态、大小以及细胞核内染色体变化极其相似，发育水平比较一致。

It indicated that mTSARG3 was involved in the meiosis by which spermatogenous cell differentiated to spermatocyte. We established mosue cryptorchidism model and disolated total RNA at different days after operation to perform RT-PCR.

为研究mTSARG3基因在精子发生中的调节作用，我们分离了小鼠不同发育阶段的睾丸总RNA进行半定量RT-PCR检测，结果显示mTSARG3基因在出生小鼠1周即有表达，在第3周时明显增高，之后保持稳定表达趋势。

Moreover, the extremely slow development of gametophyte and time interval between the appearance of antheridia and archegonia resulting from the inherent physiochemical property of red soil make it impossible to fertilize and generate sporophyte.

此外，红壤固有的理化性质导致扇蕨配子体发育极其缓慢、精子器和颈卵器发生的时间间隔过长使其不能受精产生于包子体。

Objective To localize the Mahoganoid protein and it's mRNA in the testes and epididymides of rats in different ages and study the gene's significance in spermatogenesis.

结论Mahoganoid蛋白及其mRNA在成熟大鼠睾丸和附睾组织中均有表达，二者分布基本一致，提示Mahoganoid在精子发生中可能具有一定的作用，并且睾丸和附睾具有自主合成Mahoganoid蛋白的能力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
