Immunocytochemistry localization shows SBP117 is mainly located at the bulliform cell in the leaf. Tissue printing study showed that SBPl 17 is mainly located at the epidermis of roots, shoots and leaves as well as in the vascular bundle of the rice roots and leaves. The distribution of SBPl 17 is coincided with the sites of Si accumulated in rice plants.

免疫细胞化学检测SBP117主要分布在水稻叶片的泡状细胞中；组织印迹法显示SBP117主要分布在水稻根茎叶的外表皮中，在根和叶的维管组织中也有分布，这与硅在水稻体内的分布是一致的，说明此蛋白参与控制硅在水稻体内的沉积。

Because a very low abundance of MSCs is present in bone marrow (approximately one Per 10〓-10〓 nucleated celled), ex vivo expansion produces a significant increase in the number of MSCs that can be very important.

然而，人体内骨髓中MSC的含量极其稀少，每1×〓-1×〓个单个核细胞中大约有1个MSC，组织工程中对种子细胞的数量要求巨大，如此微量的MSC难以满足组织工程的需要，因此体外纯化和扩增MSC就显得尤为重要。

The antibodies to cathepsin D and glial fibrillary acid protein and immunohistochemical PAP technique were used to observe the changes in microglia and astrocytes in the cerebella from NPC and normal mice of different ages.

Results 6 patients with PAP presented with ground-glass opacification of the bilateral lungs on HRCT. Typical chest HRCT scan showed "map-like" lesions in 3 cases and "cobble stone-like" lesions in 3 cases. Multifocal consolidative opacities in the lungs were seen on HRCT in 3 cases. Lung biopsies from 6 patients with PAP revealed a prominent positive periodic acid-Schiff intra-alveolar exudates. There were normal alveolar spetasis in 3 patients while interstitial thickening, fibroblast hyperplasia, interstitial fibrosis in the others.

结果 6例患者在不同层面可见磨玻璃影，其中2例可见小结节影；3例表现为两肺斑片状磨玻璃影与周围肺组织分界清楚，呈地图样改变；3例因磨玻璃影与小叶间隔增厚交织成铺路石样改变；3例可见肺泡实变融合成密度较高的斑片状阴影，1例在肺泡实变区可见&空气支气管征&。6例患者活检肺组织在光镜下显示肺泡腔内充满大量块状或颗粒状嗜伊红物质，PAS染色阳性，AB染色阴性，其中3例肺泡间隔正常，3例肺泡间隔增宽，可见慢性炎性细胞浸润、成纤维细胞增生和胶原沉积。

After varied survival periods, the model mice were sacrificed to get the specimens of SN fixed, embedded and coronally sectioned continuously. The microsections were processed by immunohistochemistry to label the DA neurons and Calbindin D28k-containing neurons with the antibodies against tyrosine hydroxylase and CR respectively. The labeled cells were counted under microscope and analyzed statistically.

模型动物存活1周后，一部分取其中脑黑质节段，固定、包埋做连续冠状石蜡切片，以免疫组织化学染色方法，显示各组酪氨酸经化酶和钙结合蛋白表达阳性细胞，光镜观察并细胞计数，统计学分析；另一部分取其中脑黑质组织匀浆，行TH、CB的Westem blot免疫印迹方法检测，用LabWorks软件分析处理。

From the early study of the pathogenesis of pre-eclampsia people have found its association with immunological function . In 1986 Ellis et al[1] had found that the extravillous chorionic cytotrophoblast contacting with the maternal tissue expressed high levels of Human leukocyte antigen-G, a major histocompatibility tissue-specific antigen . Extravillous chorionic cytotrophoblast with high levels expression of HLA-G proteins can invade the maternal deciduas and the maternal spiral arteries by displacing the endothelial lining and destroying most of the musculoelastic tissue of these arteries .

早期研究开始，许多学者即发现其与免疫学有密切关系，至1986年Ellis等[1]发现人类白细胞抗原(human leukocyte antigen，HLA) G分子高度表达在绒毛外滋养层细胞( extravillous cytotrophoblast，EVCT)上，即浸润至子宫蜕膜层甚至达子宫浅肌层以及子宫螺旋动脉内皮层，与母血及子宫组织直接接触的滋养细胞，这种独特的组织分布提示HLA-G分子在母胎免疫耐受方面起重要作用。

METHODS: The model of tissue damaged submandibular gland in 10 rats was made by deligation. One week later, the gland tissue was obtained to harvest submandibular gland stem/progenitor cells by enzyme digestion in vitro. Following 10-14 days of primary culture, small round cells were collected, purified and subcultured for monoclonal culture.

10只大鼠采用结扎下颌下腺主导管、抑制腺体分泌来建立组织损伤模型，1周后切取腺体组织，酶消化法体外分离下颌下腺干/祖细胞，原代培养10~14 d后，挑取培养皿中形成的小的类圆形、类上皮细胞集落予以纯化，传代后进行单克隆培养。

Staining and observing shows that the most pathological changes were interstitial pneumonia and hemorrhagic pneumonia, typical nonsuppurative encephalitis, and neurogangliitis et al. The lymphoid tissue was necrosis, and the amount of lymphocytes was reduced. The pathological changes of the positive cells, especially the epithelial cells were swell, denaturization and hyperplasy to the extent.

H.E。染色观察显示，病理组织学变化主要表现为间质性肺炎和出血性肺炎、典型的非化脓性脑炎、神经节炎等；淋巴结、扁桃体和脾脏等组织内淋巴细胞坏死、数目减少；有阳性反应的细胞，特别是阳性上皮细胞呈现不同程度的肿胀、变性、增生等病理变化。

However, the molecular mechanisms underlying premature aging up 8-MOP/UVA are as yet unknown. In our studies, dermis of the non-lesion back skin of vulgar psoriatic patients who had been treated by PUVA and the cultured foetus dermic fibroblasts were selected to be observed.

本课题以PUVA治疗寻常型银屑病患者背部非皮损区真皮及培养的胎儿真皮成纤维细胞为对象，采用HE染色、Verhoeff染色、电镜、酶组织化学、免疫组织化学、原位杂交、流式细胞计数仪、三引物PCR、PCR-SSCP技术及PCR产物直接测序等技术和方法，研究了8-MOP/UVA对皮肤光老化形成的影响及芳维A酸乙酯的拮抗作用。

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。
