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。

The results revealed that nine of the fourteen Y-specific markers cannot be used for investigating the swamp buffalo Y chromosome genetic diversity because of the reasons specified below: three microsatellites markers (INRA008, UMN0103 and UMN0504) were single allele and monomorphism, three (UMN1113, UMN0304 and BC1.2) indicated three alleles respectively but mornomorphism, and the other three (UMN0920, UMN0307 and UMN3008) showed irregular ladder-like bands. Only the remaining five microsatellites (INRA124, INRA189, BM861, PBR1F1 and UMN2001) indicated polymorphisms, and thus can be applied to study the swamp buffalo Y chromosome genetic diversity.

结果表明，3个标记（INRA008，UMN0103和UMN0504）只有1个等位基因，表现为单态；3个标记（UMN1113，UMN0304和BC1.2）均为3个等位基因，但呈单态；3个标记（UMN0920，UMN0307和UMN3008）呈现无规律的梯状条带，所以这9个标记都不适用于水牛的Y染色体遗传多样性研究；只有5个标记（INRA124，INRA189，BM861，PBR1F1和UMN2001）具有多态性，表明适用于水牛的Y染色体遗传多样性研究。

After 4 days of serum deprivation, CPR-293 cells exhibited substantial nuclear condensation and fragmentation DNA laddering but HO-1/CPR-293 cells was not apparent. Thus HO-1 expression is sufficient to protect cells from serum deprivation-induced apoptosis. In the experiment, we used primary cultures of from HO-1 fibroblasts and their wild-type littermates fibroblasts CPR-293 cell and HO!

2生理加压诱导细胞凋亡我们用稳定的CPR细胞株和HO1和CPR在一起的细胞株实验，当浆液丢失4天后，CPR-293细胞表现出有实质的核浓缩和DNA梯状条带的形成，而HO1/CPR-293细胞则没有，显示HO1是充分保护细胞，避免在浆液丢失情况下而诱导的细胞凋亡。

This article, based on the analysis of the data from the experiment on"double concrete beams", has shown the availability of using the"ladderlike concrete fabric" or"double steel" after treatment, and it has explained its properties of strength, crack and deflection.

The copper center was situated in a distorted square pyramidal (4+1) CuN3X2 coordination geometry with terpyridine acting as an equatorial tridentate ligand.

在配合物中，中心铜原子的配位环境为变形四为锥，并通过分子内和分子间的C-H…C1和C-H…O氢键作用形成三维梯状结构。

After SE, DNA ladder was seen in nucleus amygdalae where neurons were morphologically necrotic, which suggests that programmed cell death mechanisms may be activated in this SE model.

结论癫痫持续状态后，形态学上表现坏死的神经元出现梯状DNA电泳带，提示在此模型中可能存在程序性细胞死亡的机制。
