细胞坏死

Results 20 cases of CT examination had made proper diagnoses,the CT imaging finding about the most of peripheral cholangiocarcinoma included:There was the atactic low density tumour in liver,its borderline was unclear,enhanced scan appearances were irregular peripheral enhancement,centripetal enhancement,and delaying enhancement;There was concretion and dilatation of bile buct in or around the focus;The local envelope of liver was lacunose and the local liver was atrophied,There was abroad putrescence and liquescence in the focus.

结果 20例CT做出了正确的诊断，大部分周围型胆管细胞癌的CT表现为肝内不规则低密度肿块边界欠清，增强扫描表现病灶边缘呈不规则环状强化，有向心性强化的趋势，出现延迟强化；病灶内或周围可见结石，病灶内及周围肝内胆管扩张；局部肝包膜回缩、肝叶萎缩，病灶内大片坏死、液化。

Purpose To investigate if parvovirus B19 infection play a role in the pathogenesis of true histiocytic necrotizing lymphadenitis.

目的研究人微小病毒B19感染与组织细胞性坏死性淋巴结炎(histiocytic necrotizing lymphadenitis，HNL)的关系。

OBJECTIVE: To explore the effects of choline chloride and folic acid deficiency on apoptosis and necrosis in human lymphoblast cell line.

目的： 探讨胆碱与叶酸不足对人成淋巴细胞株细胞凋亡(apoptosis，APO)和坏死(necrosis，NEC)的影响。

The morphological changes in condensation and margination of nuclear chromatin, apoptotic bodies and cell necrosis significantly increased in gen group and gen plus ddp group.

形态学观察可见gen组和gen+ddp组细胞凋亡、凋亡小体及变性坏死增多，而对照组少见。

Finally, we observed that the serum TNF-α level decreased gradully in A group after transplantation, and meanwhile the electron micrography revealed that Kupffer cells became from inactivation to disruption and apoptosis.

最后，我们发现A组随着心跳停搏时间的延长，术后血清TNF-α水平不断下降，而同期电镜下可观察到Kupffer细胞从不活跃状态逐渐发展到凋亡和变性、坏死。

By necrosis is meant the local death of cells.

所谓坏死指的是细胞局部死亡。

At the same time, the morphological changes in blood vessels, neuroglia cells and neurons were observed in rats.

结果显示在电磁脉冲辐照后，海马神经细胞不仅发生快速的坏死，而且还发生凋亡，同时在早期即可见到血管、胶质细胞和神经元等组织的形态学异常。

Necrosis was observed in some of the 30 Gy-3-month-period group. Different levels of morphological changes in blood vessels,neuroglia cells and neurons were found in rats of all other groups.

在30 Gy照射后3个月组中有坏死灶的存在，而其他组别中可以看到血管、胶质细胞和神经元等组织的形态学异常。

The results indicated that EMP can promote necrosis and apoptosis of hippocampal neurons,induce morphological changes in blood vessels, neuroglia cells and neurons at early stage, which may be the possible injury mechanism in rat brain induced by EMP.

表明大鼠大脑受电磁脉冲辐照后早期海马区可发生神经细胞坏死和凋亡，以及各组织成分的病理形态学改变，上述变化可能与电磁脉冲致细胞DNA损伤有关。

Objective: To investigate the expression and function of bFGF and TNF-α in the ossification of the posterior longitudinal ligament of the cervical spine.

目的：探讨碱性成纤维细胞生长因子和肿瘤坏死因子在颈椎后纵韧带中的表达水平及在骨化发病机制中的作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
