The Production and Effect of Nitric Oxide in Respiratory Syncytial Virus-infected Human Lung Epithelial Cells 呼吸道合胞病毒感染人肺上皮细胞一氧化氮的产生及其作用
Culture of Human Respiratory Syncytial Virus A_2 Strain in Various Cells and Its Influencing Factors 人呼吸道合胞病毒A2株在不同细胞中的培养及其影响因素
Histologic examination showed that the numbers of villi with syncytial cell node, vascular syncytial membrane and hyperplasia, Langerhans ′ cells, villus fibrinoid necrosis in high altitude group were all higher than those in control group ( P < 0.01). 组织学检查:具有合体细胞结节、血管合体膜、血管增多、朗罕氏细胞、绒毛纤维素样坏死等绒毛均高于对照组(P<0.01);
Ultrastructural observation in high altitude group showed significant hyperplasia of syncytial cells and Langerhans ′ cells in placenta villi, high expansion of rough surfaced endoplasmic reticulum and very thick trophoblastic basement membrane. 超微结构观察:高原胎盘绒毛的合体细胞及朗罕氏细胞增生明显,粗面内质网高度扩张,滋养叶基底膜明显增厚,可达正常的几倍至十几倍。
On the free surfaces of syncytial cells, fibrous deposition was sccn and the basal membrane of these cells was thickened. 在合体细胞游离面有纤维蛋白样物质沉着处,基底膜往往同时增厚。
Expression and transfection of respiratory syncytial virus M_ ( 2-1) gene in human lung adenocarcinoma PAa cells 呼吸道合胞病毒M(2-1)基因在人肺腺癌PAa细胞的转染及表达
Results: The following features in calcification area were found: Microvilli of placental villus syncytial cells were decreased significantly and lost normal shape; 结果:与无钙化区相比,足月妊娠胎盘钙化区的超微结构特征有:绒毛合体滋养细胞微绒毛变形、减少;
Value of Heparin Blocking Attachment of Respiratory Syncytial Virus to Human Airway Epithelial Cells 肝素阻断呼吸道合胞病毒与呼吸道上皮细胞黏附作用
Under electron microscopy, there were swelling and decrease in number of micro-villi, and dilatation of rough endoplasmic reticulum in all syncytial cells, and swelling of mitochondria and increase of lysosomes in part of syncytial cells, and swelling of endothelial cells in some fetal capillaries 电镜下合体细胞微绒毛肿胀、稀少、粗面内质网普遍扩张,部分合体细胞线立体肿胀、溶酶体增加、胎儿毛细血管内皮细胞肿胀等改变
