The cell morphology, transepithelial electrical resistance, mannitol efflux rate and alkaline phosphatase activities were monitored during culture. 采用细胞形态学、跨膜电阻值、甘露醇透过率和碱性磷酸酶活性等指标对细胞模型进行检测。
Transepithelial nasal PD was assessed in23 patients in the first cycle and in21 patients in the second cycle. 第一循环有23名病患、第二循环有21名病患评估经上皮鼻电位差;
Aim To study the kinetics of uptake, transepithelial transport and efflux of9-nitrocamptothecin ( 9-NC). 目的研究9-硝基喜树碱(9-NC)的细胞摄取、转运及外排特性。
PURPOSE A human intestinal epithelial membrane model system ( Caco-2) cultured in vitro had been applied to study the drug uptake, efflux and transepithelial transport at small intestine. 一种体外培养的人小肠上皮细胞模型(Caco-2)已应用于药物在小肠细胞中的摄入、排放和过细胞输运等过程的研究。
Regulation of Nitric Oxide Production in the Ciliary Processes and the Role of Nitric Oxide in the Cliary Transepithelial Ionic Transport 一氧化氮在睫状体中的合成及其对睫状体上皮跨细胞离子转运的调控
Conclusion Exogenous EGF can improve the transepithelial liquid transport and abate pulmonary edema in rats with inhalation injury. EGF治疗组ALC在伤后48h即可恢复到正常水平,肺水量显著减少,肺组织病理改变明显减轻。结论外源性EGF经气管喷入能提高大鼠肺泡液体转运能力,减轻或消除肺水肿。
Effects of the Transepithelial Voltage on the Apical Chloride Channels of Frog ( Rana Temporaria) Rectal Epithelium 跨上皮电位差对蛙直肠上皮顶膜氯通道的作用
The experimental results showed that the transepithelial voltage is essential to the absorption of chloride ion across the frog rectal epithelium, because it could activate the chloride channels in the apical membrane of frog rectal epithelial cells besides as a driving force. 实验结果表明跨上皮电位差对氯离子跨蛙直肠上皮吸收是必不可少的。跨上皮电位差作为转运驱动力外,还能激活蛙直肠上皮细胞顶膜的氯通道。
Transepithelial electrical resistance ( TER) was detected and the permeability was measured with fluorescein sodium ( FS) and horseradish peroxidase ( HRP). 行跨膜电阻测定并用荧光素钠和辣根过氧化物酶(HRP)进行通透性检测。
METHODS Based on the two-compartment primary Sertoli cells culture model, the effects of phthalates on the tight junctions of Sertoli cells were studied by the methods of light microscope, transmission electron microscope, transepithelial electrical resistance assay and immunofluorescence localization. 方法建立大鼠睾丸支持细胞原代双室培养模型,通过光镜、跨上皮电阻测定及免疫荧光定位方法研究PAE对大鼠支持细胞及支持细胞间紧密连接结构的影响。
When the aqueous side is negative, the polarity of PD was found to depend on the concentration of Cl-in the solution and this likely indicated that Cl-was the main composition to generate the transepithelial PD of human ciliary epithelium. 3. 房水侧PD极性依赖于细胞外Cl-的浓度,Cl-可能是人眼睫状体上皮跨膜电位产生的重要成分。
The transepithelial PD may be positive or negative at aqueous side in human ciliary epithelium. The polarity is not related to the post-enucleated time of eye balls. 人眼跨睫状体上皮电位差PD可表现为房水侧正性或负性,与睫状体组织离体的时间无相关性。
When the epithelium is wounded, the transepithelial potential will drive current out of the disrupted area, and create the endogenous electric field in turn. 当上皮细胞层受到破坏时,跨细胞层的离子流驱动电流流出,形成局部内源性电场。
