查询词典 staining

The apoptotic effects of LPS are detected by various skills such as fluorescence staining, TUNEL reaction, DNA agarose gel electrophoresis, electron microscopy and fluorescence activated cell sorting. Our results demonstrated that fish lymphocytes would be apoptotic under different LPS concentrations(above 10μg/ml) and different time(above 6h) inducing, which is characterized by condensation and margination of chromatin, the formation of apoptotic bodies.

结果显示，在10μg/ml以上浓度的内毒素作用18后或以100μg/ml浓度的LPS作用6h以上，淋巴细胞即可出现明显的凋亡形态学变化，表现为染色质凝集和周边化，核断裂，形成凋亡小体，DNA发生特异降解产生典型的"梯状"电泳图谱，呈现TUNEL阳性标记等，并通过流式细胞术证实这种凋亡具有时问和剂量的依赖性。

Objective: To develop a compound staining method showing collagenic, elastic fibers and melanocyte in skin tissues.

目的：寻找能显示皮肤组织黑素细胞与胶原纤维和弹力纤维的染色法。

The staining pattern was cytoplasmic and/or membranous.

DOG1.1表达的阳性部位为胞浆或/和胞膜。

Prussian blue staining revealed more than 98% of BM-MNCs were labeled by Feridex and BM-MNCs appeared to be unaffected by magnetically labeling. Three dogs injected Feridex- BM-MNCs were visualized at one week by MRI, but none of unlabeled BM-MNCs were seen. All lesions that were detected within one week could not be visualized over four week. The dot injected Feridex-cells which fixated by 4 % methanal also was seen at one week by MRI, but the signal disappeared at two week.

普鲁士蓝染色显示体外Feridex标记BM-MNCs成功率达98%以上，而且细胞活性不受影响；其中3只实验犬标记细胞移植区1周内可用1.5T磁共振仪3DSSFP序列在体扫描到T2低信号影像，4周时该低信号消失；同样条件下经甲醛固定的标记细胞在1周时也可检测到T2低信号，但2周时该低信号消失；未标记细胞移植区没有检测到低信号。

After using the methenamine silver-DNA staining,15 cases of eariy molluscum contagiosumtissues were examined by electron microscopy.

用DNA银染技术显示了传染性软疣病毒形态发生发育及其过程中DNA的变化。

The lung of rats were made into lung print smears and lung sections. Pathological changes in lung tissues was observed after staining with gormori methenamine silver and hematoxylin-eosin.

第9周时剖杀，取肺制作肺组织印片和肺组织切片，分别采用六胺银和苏木素－伊红染色，观察病理学变化。

Objective To study the value of endoscopic methylene blue staining in the diagnosis of gastric precancerous lesions.

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。
