Results: Of all the semen samples, 8 were HCMV positive, 4 HSV-Ⅱ positive, but none were both HCMV and HSV-Ⅱ positive. HCMV late antigens were positively and HCMV early antigens negatively expressed in the spermatogenic cells of the 8 HCMV positive cases. In the 4 HSV-Ⅱ positive cases, 3 were positively and 1 weakly positively expressed. In the semen of the 12 positive cases were found large numbers of immature spermatogenic cells, with different manifestations of apoptosis, such as chromatin pycnosis, vacuoles, damaged nuclear membrane, and apoptotic bodies, but without virus infection-induced specific morphological alteration.

结果：83例精液样本PCR检测HCMV阳性8例，HSV-Ⅱ阳性4例，未发现2种病毒同时阳性病例。8例HCMV阳性病例ICC标记生精细胞HCMV晚期抗原均见阳性表达，HCMV早期抗原均为阴性表达；4例HSV-Ⅱ阳性病例ICC标记生精细胞3例阳性表达，1例弱阳性。12例病毒阳性病例均发现较多未成熟生精细胞，并有不同程度的核染色质固缩、出现空泡、核膜破损、核崩解、凋亡小体等凋亡现象，但未能找到病毒感染的特异性形态学改变。

Wear resistance less than YG3X only,sensitive to impact and vibration.Used for continuous semifinish turning of cast iron,nonferrous metals and their alloys and for finish turning.

耐磨性仅次于YG3X，对冲击和振动较敏感，适用于铸铁、有色金属及其它合金连续切削时的精车、半精车、精车螺纹与扩孔。

At postnatal 1st week immunopositive reaction of NGF was detected mainly in sustentacular cells and the spermatogonia also showed positive staining. NGF positive staining in the testes was observed in interstitial cells, spermatogenetic cells, sustentacular cells and Leydig cells at 3rd week. After the postnatal 5th week, NGF-positive immunostaining was also detected in intersitial cells and spermatogenetic cells, but the intensity of reaction was weaker than that at 1st and 3rd weeks.

免疫组化定位分析显示：睾丸组织的神经生长因子蛋白表达于小鼠出生后的各个时期内，1周龄睾丸组织免疫阳性反应主要位于支持细胞，精原细胞也有着色；3周龄睾丸组织的间质细胞、各级生精细胞、支持细胞、管周肌样细胞表达均呈现阳性；5周后的睾丸组织内神经生长因子呈低水平表达，主要表达于间质细胞和生精细胞内。

Objective:To study the biological features of mouse spermatogonial stem cells,in order to indentify spermatogonial stem cells and to realize the features in vitro.

目的：探讨培养状态下精原干细胞的生物学特征，为体外鉴定精原干细胞及认识精原干细胞在体内的生物学行为打下实验基础。

Objectives:To establish the culture system of spermatogonial stem cells in vitro;To study the mechanism of proto-oncogene c-src on the proliferation of rat spermatogonial stem cells.

目的：探索及完善精原干细胞的分离、鉴定和体外培养技术；研究原癌基因c-src在体外培养的大鼠精原干细胞中的表达及其与精原干细胞增殖相关的信号通路。

Based on the experiment of dissolving EPS plastics by two essential oils, 1g terpenoid oil dissolves 0.65g EPS plastics, after dissolving the volume of EPS plastics decreases to 5%; terpeneless compound can not dissolve EPS plastics.

实验研究了两类精油对发泡聚苯乙烯塑料的溶解效果。1g萜烯烃类精油溶解0.65g发泡聚苯乙烯塑料，溶解后的塑料体积约为原体积的5%。低萜精油不能溶解发泡聚苯乙烯塑料。

They can reach 72.04% and 84.5% separately(P.05). 2. The methods such as Percoll uncontinuous density gradient centrifugation, isolation according to the different adhesiveness can be used to isolate and purify rabbit SSC effectively. Spermatogonia mainly distribute between the gradient 27% to 35%(density between 1.0410g/ml to 1.0508g/ml).

Percoll 不连续密度梯度离心和差异粘附等方法可以有效的对兔精原细胞进行分离纯化，其中精原细胞主要分布于密度梯度为27%-35%(密度 1.0410g/ml~1.0508g/ml)的带间，此带中精原细胞的纯度平均达到 60.42%(P.01)。

A blue is often smaller than an average goblin, with noticeably blue-tinged skin, unsloped forehead, and eyes less dull than usual.

蓝地精往往比普通地精矮小，有着一身引人注目的淡蓝皮肤、比较不倾斜的前额以及比普通地精更为呆滞的眼神。

Vasostomy can reverse germ cell apoptosis due to Vasoligation; Bcl-2 gene inhibited apoptosis of spermatogenic cells; Vasoligation and Vasostomy have a effect on transcript level regulation of Bcl-2 gene

大鼠输精管阻断所致的生精细胞凋亡加剧现象是可复的，阻断解除后生精细胞凋亡逐渐减轻并恢复至阻断前水平；Bcl-2基因在输精管复通后生精细胞凋亡减轻中发挥了抗凋亡作用；输精管阻断及复通过程中存在Bcl-2基因转录水平的调节。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
