Full protection was achieed when protectie cells were transferred 3-4 days before diabetogenic cells, whereas transfer 2 days before conferred only partial protection.

注射致糖尿病细胞前3-4天给大鼠给予保护性细胞能得到完全性的保护，而提前2天则只能获得部分性的保护。

Objective To construct retrovirus vectors carrying IL17 or siRNAIL17 genes with Thy1.1 gene and determine the infected ability of the retrovirus vectors to diabetogenic BDC2.5 T cells.

目的 构建含有Thy1.1细胞表面抗原(Thy1.1 cell surface antigen，Thy1.1)基因的携带IL17或siRNAIL17基因的逆转录病毒载体，并观察逆转录病毒对致糖尿病性BDC2.5 T细胞的转染能力。

I n this research apoptosis of keratinocyte induced by interferon-γ and anti-Fas monoclonal antibody, mimicking down stream in the cascade of the pathogenesis of eczematous dermatitis, was used as an in vitro experimental model to screen drugs which can inhibit cell apoptosis.

通过比较SRB和MTT两种检测方法选用更敏感、准确的SRB方法以及用流式细胞仪同步监测SRB检测结果，建立了用SRB初步筛选抗细胞凋亡药物的方法，从而为筛选湿疹性皮炎的治疗药物奠定了实验基础。

Thus, endogenous Smad2 actiation is indispensable for endodermal and mesodermal induction in the early phase.

晚期阶段，TGF-beta通过介导Smad2活化，调节心肌细胞的增殖与分化，实现其负性调节心肌细胞生成的作用。

A clear cause-and-effect relationship between excessive myocardial MMP-1 activity, increased mysial collagen degradation, and progression to systolic HF has been shown experimentally through the use of transgenic models and the use of pharmacological MMP activators.53,54 In addition, experimental evidence has been provided showing that following chronic neurohormonal activation, increased synthesis and release of MMPs into the local extracellular matrix of the cardiomyocyte occurs,55 which in turn could contribute to endomysial and perimysial collagen degradation and disruption.

一个明显的因果过多的心肌MMP-1关系活动， mysial增加胶原蛋白的降解和进展收缩性心力衰竭已被证明试验，通过使用转基因模型和使用的MMP药理作用此外，activators.53，54实验证据下面被提供显示慢性神经激活时，增加的MMPs合成和释放到当地的细胞外基质的心肌细胞发生，55反过来有助于人肌内膜和 perimysial胶原退化和破坏。

VEGF can specifically increase the dividing, proliferation and movement of endotheliocyte, as well as the permeability of tumor vessels, making it a crucial angiogenic factor in research.

血管的生成机制中，血管内皮生长因子(vascular endothelial growth factor，VEGF)是重要的直接作用于血管内皮细胞的生长因子，可以特异性地促进内皮细胞分裂、增殖、移动，增加血管的通透性，在血管形成中起重要作用，是目前特别受重视的血管生成因子之一。

As an immunomodulator NO may play a role like a double-edged sword since it expresses both in immuonchalleged and immunosspresed states. 2. After received external stimulus the morphology of ependyma of SFO could be changed and varied with time course, particularly its cellular apoptosis do occur and earlier than the ordinary areas of the brain. 3. Astrocytes in SFO could express cFos protein induced by LPS, suggesting the cells may maintain homeostasis in the brain in a longer period and modulate immune state of the brain. 4. As a CVO, SFO may sense changes of blood-bearing immunosignals earlier and instantly response to them, thus as one of windows of the brain SFO do take part in immunomodulation within the brain.

通过我们的实验结果我们可以得出这样一些初步的结论：1、一氧化氮作为免疫调质参与了机体免疫，它既能在免疫激发状态下又可在免疫抑制状态下进行表达提示，NO在脑内免疫调节中的作用可能是双向的。2、穹窿下器的室管膜形态在接受外界刺激后，随着时间的变化而不同，扫描电镜下的凋亡形态虽需进一步证实，但室管膜细胞确实发生了凋亡，并且穹窿下器发生的较早。3、穹窿下器内的星形胶质细胞在给予大肠杆菌后确实可以表达c-fos蛋白，并可能通过自身的激活来较长时间的维持体液的动态平衡，调节脑内免疫状态。4、穹窿下器作为感受性室周器官之一，能够较早的感受血携免疫信息的改变并及时作出反应，可能作为外周免疫信息进入脑内的窗口之一来参与脑的免疫调节。

Methods Rat spinal cord injury models were established by aneurysm clip compression, and nestin expression and proliferation of ependymal cells at different times were shown with pathological and immuno-histochemical staining.

应用动脉瘤夹压迫建立大鼠脊髓损伤模型，通过组织病理学及免疫组织化学方法检测不同时段室管膜细胞的反应性增生和神经外胚层多潜能细胞特异性抗原nestin的表达。

Using electronic microscopy and cytochemical methods, we studied the distribution changes of the cell ergastic substance and development of secondary vascular tissues. Development of secondary vascular tissue took on an inherent rhythm, showing alternation of dormant and differentiated stages in periodicity of one year, and the formation of secondary phloem and xylem was alternate.

利用电镜技术及细胞化学方法，研究了美洲黑杨次生维管组织的发育以及细胞内含物分布的变化，发现次生维管组织的发育具有内在节律性，在年周期中表现为分化期和休眠期交替出现；次生韧皮部与次生木质部交替分化形成。

Kaposiform hemangioendothelioma is a very infrequent, locally aggressive vascular neoplasm, characterized by fascicular spindle cell proliferation.
