ABSTRACT Aim To study the safety and the immunogenicity of PVRV.

摘 要 目的研究Vero细胞狂犬病疫苗的安全性和免疫原性。

Increased level of LM and Col protein resulted in reduced cell monolayer permeability.

高水平的层粘连蛋白和IV型胶原使细胞的通透性减低。

Pathologically, it showed palisaded granulomas containing degenerated collagen, predominantly lymphohistiocytic infiltration with scattered eosinophils leading to dermal fibrosis.

在病理下可发现有栅栏状排列的组织球围绕著变性的胶原纤维，而浸润的发炎细胞主要由淋巴球、组织球与散在性的嗜伊红球至后续的真皮层纤维化。

The data obtained in both groups were analyzed by using Student t test, product moment correlation, and multiple regression analysis.

结果：（1）HIFU组原发灶肿瘤组织出现凝固性坏死，未检测到凋亡的肿瘤细胞，而对照组为1.10±0.76/HPF。

Results］the gross morphology of the tendons showed the experimental group had lesser adhesion and better reactiveness than that in the control group.the fibrin had degraded at 3 weeks. cell tracing showed that the labeled bone marrow derived mesenchymal stem cells remained viable and presented in the intratendinous region for at least 6 weeks, becoming more diffuse at later timepoints.at 3 weeks, collagen fibers appeared more organized and there were better morphometric nuclear parameters in the treatment group. at 6 and 12 weeks, there were no differences between the groups with regard to morphometric nuclear parameters.

结果］实验组相比对照组肌腱大体观察粘连差，肌腱活动性好。3周后纤维蛋白载体即降解，细胞示踪结果显示标记的骨髓间充质干细胞至少6周内仍可保持活性并存在于肌腱组织中，但之后逐渐扩散。3周时，实验组与对照组相比胶原纤维排列更为有序，且胞核形态结构更规则，但在6周及12周时，实验组与对照组胞核参数测定无统计学意义。3周时实验组比对照组具有更强的的生物力学特性，但之后则差别不明显。

Results there were unconsciousness, respiratory rhythm disturbance and hyporeflexia of pupil light reflex immediately after injury, and reactiveness decrease and activity retardation still existed even after resuming consciousness. at anatomical scene, subarachnoid hemorrhage or cerebroventricular haemorrhage were widespread. at an early stage, there were swelling, collapse, and axonal retraction ball formation at cortico-medulla junction, callosum, brainstem, and cerebellar white matter under microscope. but at the later stage, gitter cell proliferation and nest-like aggregation were major pathophysiological changes at focal brain tissue.

结果 伤后大鼠均即刻出现原发昏迷，其中2只于损伤后20 min内死亡，余持续时间1-30 min不等；伤后大鼠呼吸节律紊乱，瞳孔对光反射减弱或消失，醒后均有程度不等的反应性下降，肢体活动迟缓；肉眼可见广泛蛛网膜下腔出血或脑室出血；光镜下可见皮髓交界区、胼胝体区、脑干、小脑白质等部位的神经轴索有不同程度的肿胀、断裂、轴索球形成，后期有小胶质细胞增生，局部呈巢样聚集。

Grens syndrome,also called sicca syndrome, is a chronic and inflammatory autoimmune disorder characterized by the progressive lymphocytic and plasma cell infiltration of salivary and lacrimal glands, which eventually results in xerostomia and xerophthalmia.

grens syndrome， SS），也称干燥综合征，是一种慢性炎症性自身免疫性疾病，病理特征为大量淋巴细胞和浆细胞进行性浸润涎腺和泪腺。临床表现为口干、眼干，根据是否伴有全身结缔组织病，SS可分为原发和继发两个类型。

Methods: By immunohistochemical methed, the expression of Bcl-2 and Bad gene were observed in eight cases with normal breast tissue, 19 breast hyperplasia and 20 breast atypical, as well as 48 with breast cancer in situs.

近年来，国内外有关在细胞凋亡调控中起重要作用的Bcl-2家族基因与乳腺癌关系的研究日益受到重视，部分学者认为乳腺增生病是乳腺组织从正常→单纯性增生→非典型增生→原2005年第32卷第10期位癌→浸润性癌的过程，是一个渐进的演变过程，非典型增生是癌变过程中必经的一个阶段。

NPC displays a type Ⅱ latent phenotype expresing the subdominant proteins of EBNA1, LMP1 and LMP2 only.

肿瘤细胞中病毒蛋白呈潜伏Ⅱ型表达，即仅表达低免疫原性抗原EBNA1、LMP1、LMP2。

Core protein, which is very conservative, can induce high level of humoral and cellular immunity. For these years, Core antigen was expressed in E.coli successively. But E.coli is uncapable of managing gene expression and protein procession like eukaryotic cell.

HCV核心蛋白高度保守且有很强的免疫原性，可诱发高水平的特异性体液免疫及细胞免疫，是HCV诊断试剂中必不可少的组分之一。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

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。
