The results indicated that in the FNAC smears of mediastinal tumor, neutropilic myelocyte, neutropilic metamyelocyte, neutropilic stab granulocyte and neutropilic segmented granulocyte were observed in granulocytic series; early normoblast, polychromatic normoblast and orthochromatic normoblast were observed in erythrocytic series; and granular megakaryocyte, thromocytogenic megakaryocyte, scattered platelet and matured lymphocyte also were observed. Cell morphology and distribution in different stages were are similar to that in bone marrow smear, and these cells belong to the extra-medullary hemopoietic tissue.

结果表明：纵隔肿块的细针抽吸活组织的细胞学涂片显示粒系细胞中可见中性中幼粒细胞、中性晚幼粒细胞、中性杆状粒细胞、中性分叶核粒细胞；红系细胞中可见早幼红细胞、中幼红细胞、晚幼红细胞；并可见颗粒巨核细胞、产血小板的巨核细胞、散在血小板及成熟淋巴细胞；细胞形态及各期细胞分布与骨髓片相似，为髓外造血组织。

The concentration of diluted rv virus solution was determined by counting the nih3t3 cells with fluorescent expression. then the rv/egfp virus was used to transfer sk n sh neuroblastoma cells. the transfection efficiency in sk n sh cell was measured by flow cytometer.

将稀释的rv病毒液感染nih3t3细胞，计数nih3t3荧光表达细胞的数量来确定病毒的浓度；使用rv载体感染sk n sh细胞，通过流式细胞学荧光检测明确rv在sk n sh细胞的感染效率。

This suggests that the cytological changes in sieve element and nectariferous tissue are closely associated with the nectary functional activities.

这反映了蜜腺发育过程中筛分子和蜜腺组织的细胞学变化是与蜜腺的生长、发育和生理功能的完善联系在一起的。

The spermatogenic states of 38 azoospermic men were evaluted use fine needle aspiration cytodiagnosis and bioptic gun testicular tissue pathologic assessment.

MethodsA retrospective analysis was performed on 48 cases with the neuroma of the neck.

方法对48例患者行术前超声检查，并与穿刺细胞学及术后病理结果进行对照分析。

2Its one of cytology mechanisms of Qiang-gu-bao decoction on preventing and curing diabetes osteoporosis were related with promoting for osteoblastic cell proliferation 、 differentition and mineralization of formation,moreover inhibiting nonenzymic glycation reaction and reducing the formation of AGEs on the early stage, inhibiting the secretion of osseous absorptive cytokine, Consequently, Qiang-gu-bao decoction could inhibited bone resorption and promote for bone formation as well as regulated the bone metabolization.

2强骨宝方直接提取液及糖尿病模型大鼠载药血清均能促进 OB 增殖、分化及矿化成骨作用，并抑制早期糖基化反应，减少 AGEs 的形成，抑制 OB 分泌骨吸收因子，从而达到抑制骨吸收、促进骨形成、调节骨代谢，这可能是强骨宝方防治糖尿病性骨质疏松的细胞学机制之一。

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。
