细胞坏死

In this study we demonstrate that RA patients on anti-TNF display a paucity of follicular dendritic cell networks and germinal center structures accompanied by a reduction in CD38+ GC B cells and peripheral blood memory B cell lymphopenia compared with healthy controls and RA patients on methotrexate.

本研究表明与健康者和服用甲氨蝶呤的类风湿关节炎患者比较，接受抗肿瘤坏死因子治疗的患者缺乏滤泡树突细胞网路和生发中心，伴随有CD38+ GC B细胞和外周血记忆B淋巴细胞的减少。

Results CTL was highly specific against autologous cancer cells by inducing apoptosis or lytic necrosis.

结果 CTL对自体胃癌细胞有特异性杀伤作用，可使靶细胞凋亡或溶解坏死。

Objective To evaluate the nephroprotective effects of transplanting metanephric mesenchymal cells into the renal subcaspsule of rats with acute tubular necrosis induced by gentamicin.

目的 将胚胎后肾间充质细胞移植到大鼠右肾包膜下，探讨移植细胞对宿主急性肾小管坏死的保护作用。

Objective To detect necrotic and apoptotic cells effectively and simply by flow cytometry.

目的 以流式细胞术法简便、有效地检测凋亡和坏死细胞。

Results The main histopathologic changes were:① experimental group: inflammatory cell infiltration (1W); inflammatory cell disappearance, fibroblast and capillary tachyauxesis, osteoid tissue and small amount neoformative bone tissue appearance (2 W); fibrous tissue decrease, neoformative bone tissue enlarging and maturity (1～3 M).

结果① 实验组：术后1周，骨缺损区周围有炎性细胞浸润，可见牙槽骨变性坏死；术后2周，炎性渗出明显吸收，成纤维细胞、毛细血管生长活跃，可见骨样组织和少量骨组织；术后1～3个月，新生骨组织范围扩大，钙化程度加强。

It is suggested that inherited deficits in DNA repair mechanisms can cause neuronal damage and neurological deficits in neurodegenerative diseases.

细胞凋亡是在基因调控下启动自身机制而产生的有别于坏死的主动性细胞死亡过程。

Result: Histopathologic chronic rejection in liver biopsies might include perivenular hepatocyte dropout, necrosis, hemorrage or fibrosis, sometimes accompanied by hepatocyte ballooning or cholestasis. but without cholangitis and obliterative arteriopathy.

结果： 肝移植后慢性排斥反应可见肝小叶中央静脉周围肝细胞消失、坏死、出血、纤维化，部分伴有肝细胞淤胆、气球样变性，但未见胆管消失及阻塞性动脉病。

Results :We reported a case of esophageal tuberculosis of a 48-year-old male with symptoms of dysphagia and pectoralgia for one month.

病变组织和淋巴结病检显示上皮细胞和郎格汉氏细胞增生，伴有干酪样坏死，无恶变。

On the basis of successful culture of periosteal cells in vitro. Methods The tibial periostea of new born dog were excised and cultured under aseptic conditions.

目的 在体外培养骨膜细胞成功的基础上，进一步探讨骨膜细胞移植对缺血性坏死的股骨头的修复作用。

RESULTS: Large numbers of oval cells appeared in the periportal regions 4 wk after the induction of carcinoma, and these cells were OV-6-positive.

结果： 诱癌4 wk，大鼠肝门管区及坏死区内均见大量卵圆细胞，这些细胞呈OV-6染色阳性。

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。
