坏死后的

Presented with early artery enhancement and immediate wash out ,Two cases presented with wash in quickly and wash out slowly .The enhancement pattern of 36 liver metastatics cases was divided into the little blood provides group and the much blood provides group . The 5 cases of haemangioma were enhanced centripetally in portal phase and washed out after several minutes without arterial enhancement.

通过造影后的表现还可明确提示以下几个方面：（1）肿块内的坏死区；（2）在延迟相发现了肝内小转移灶，从而改变了临床治疗方案；（3）滋养动脉的显示；（4）门脉内栓子的鉴别诊断。36个转移性肝癌病灶分为少血供转移癌组和多血供转移癌组。6例肝血管瘤中5例均表现为向心性环行持续缓慢充填，另一例9mm的小血管瘤表现为完全、快速向心填充。

The following methods were used in the study, such as viral inoculation of animal, pathological method, flow cytometry, RT-PCR, in situ hybridization, immunohistochemistry and terminal deoxy nucleotidyl transferase mediated dUTP nick end labling . Morphological changes of the infected chickling, dynamic changes of T, B cells and T subsets, changes of adhesion molecules on the lymphocyte surface, necrosis and apoptosis of lymphocyte and neurons, changes of MIP-1β and IL-8 producing cells in the brain, cell types of perivascular tuffing in cerebral tissue were systematically studied.

在研究过程中，采用了病毒接种技术、普通病理学研究方法、流式细胞仪技术、RT-PCR技术、原位杂交技术、免疫组化技术、凋亡细胞末端标记技术，系统研究了不同日龄的SPF雏鸡人工感染AEV-NH937株后的病理变化，T和B淋巴细胞、T淋巴细胞亚群的动态变化规律，淋巴细胞表面某些粘附分子的变化，淋巴细胞和神经元的坏死与凋亡，雏鸡脑组织中产生趋化因子MIP-1β和IL-8细胞的变化规律，脑组织中围官性细胞浸润的细胞类型。
