组织形态学

As a supplement of conventional CT, CT perfusion imaging can reveal the perfusion informations of tissue or organs, such as hemodynamics, microcirculation status. It is helpful not only in finding morphologic changes, but also in providing functional and metabolizable information about the circulation parameters of hepatic diseases. So, it is valid for studying liver disorders by providing functional information, especial for the differential diagnosis and assessment for therapeutic response.

作为常规CT的一种补充，它能提供组织器官微循环状况、血流动力学变化等其它灌注参数，对肝脏病变除了能显示解剖形态学改变，还能了解血流动力学状态等反映功能、代谢变化的信息，在肝脏疾病的影像诊断与鉴别诊断等方面具有重要的作用，特别是对各种治疗方法的疗效评估及监测具有指导意义。

C2C12 cells were induced to differentiation into muscle cells in vitro and the myogenesis model was detected by inverted microscope, RT-PCR, western-blot, cell immunofluorescence histochemistry, flow cytometry and confirmed to be successful. On the foundation of differentiation model, miR-206 was detected by northern hybridization and the result showed that the expression level increasing gradually during muscle differentiation with a character of phase specificity.

利用C2C12细胞在体外成功诱导其向成肌细胞分化，通过形态学观察，RT-PCR、western-blot、细胞免疫荧光组织化学及流式细胞仪等方法进行检测，证实我们所建立的细胞分化模型是成功的，并观察到随着诱导时间的延长，miR-206在成肌分化过程中表达量逐渐增高的，表达改变具有阶段特异性。

Expression analyses identified increased expression of numerous TGF-beta-related genes that regulate cell proliferation and survival and plausibly contribute to myxomatous valve disease.

他们注意到，多数效应器分子的表达增加降低了TGF-β的信号作用，包括可诱导TGF-β的H3基因、内皮素-1、组织抑制因子金属蛋白酶1、致骨形态学发生的蛋白和&调节细胞增生和存活可能还有促进粘液瘤性疾病的基因&。

Results: Ultrasound treatment improved the morphologic features and histologic characteristics of the repair cartilage compared with nontreated controls.

结果：超声组修复软骨的形态学和组织学特性优于对照组。

The connection with other nucleis of the pallial thickening were studied by retrograde tracer horseradish peroxidase and fluorescent tracer dextran tetramethylrhodamine, Fluoro-ruby.

本研究采用Nissl染色法、golgi -cox法、神经元逆行追踪标记辣根过氧化物和逆行荧光染料葡聚糖四甲基罗丹明方法，分析了蛤蚧皮质加厚区的核团长度、核团体积、细胞大小、细胞形态、细胞密度、初步的亚区分区以及核团的纤维联系，为阐明爬行动物-蛤蚧的视觉通路核团的特征和纤维联系积累形态学和组织学资料。

Results (1) A typical pectus deformity occurred in rat underwent cutting off the lower three couples of costal cartilages bilaterally near the sternum, its presentation of pectus deformity can be compared with that in patients. 12 rats with PE who were performed Nuss procedure were survived without died from operation and the resume course was smoothly, all but three obtained desired configuration of chest wall.

4周龄SD大鼠134只，通过以不同方式切断或切除下位三对肋软骨观察术后胸廓发育，并对再生肋软骨进行形态学观察和免疫组织化学染色；用&Z&字形钢针对漏斗胸模型大鼠实施仿Nuss手术，通过胸廓外观和CT扫描进行评价：结果进行统计学分析。

HE's photomicrographs were analyzed for morphology. The proteinic expression of cyclophilin A was observed by immunochemistry. The mRNA's amount of ICAM-1 and P-selectin were quantitated by real-time quantitative reverse-transcript PCRs. All replicate data are expressed as mean±SEM.

每组随机取4例标本通过HE染色切片进行血管形态学分析，并使用免疫组织化学染色方法分析亲环素A在蛋白质水平的表达情况；另每组随机取7只小鼠通过实时定量反转录方法检测ICAM-1与P-选择素mRNA的表达。

METHODS: Pterygial specimens harvested from clinical operations received morphology, immunohistochemistry and immunofluorescence under a confocal microscope.

对手术切除的翼状胬肉标本进行形态学、免疫组织化学和免疫荧光共聚焦显微镜观察。

RESULTS On HE staining, acinar cells in the pancreas showed pyknotic nuclei and formation of apoptotic bodies, which is the typical morphological features of apoptosis.

结果 HE染色观察到胰腺组织中典型的细胞凋亡形态学特征：细胞核固缩及凋亡小体形成。

Histological observation showed that normal structure was observed in all the groups before being harvested or after being preserved for 30 minutes. However, the more severe structure damage was observed in HPCs or hepatic sinusoidal cells with the more prolonged rewarm ischemia.

形态学观察发现，四组供肝于离体前及低温保存30分钟时的组织结构均无明显异常改变；而在复温缺血期间，各组供肝肝实质细胞及肝窦内皮细胞则表现有不同程度的结构损伤，且在程度上也与复温缺血时间呈明显的平行关系。

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。
