外界膜

移植1周后，供体视网膜神经上皮层发育出典型的玫瑰花结，形成感光细胞内外节和外界膜，外丛状层发育不成熟；

After 1 week , the cografts developed rosettes , and the photoreceptors in the rosettes had well developed outer segments ( OS ) and an outer limiting membrane ( OLM ), but the OPL was immature .

结果显示：NGF广泛分布于正常神经上皮及其内、外界膜和周围间充质中；

The results were as follows : the NGF and trkA were extensively expressed in the neuroepithelia , internal and external limiting membranes and their surrounding mesenchyme in normal groups .

电镜结果显示，川芎嗪可减缓rd小鼠外核层细胞和视网膜光感受器细胞外段盘膜部位线粒体的病变，减少盘膜和外界膜的破坏。

Results from electron-microscope showed that ligustrazine could reduce lesions occurrence in the photoreceptor cells and the destruction in disc member , mitochondrion , and outer limiting membrane in the photoreceptor outer segment were decreased in rd mice by the comparison with control group .

结论：CSC患者神经上皮层脱离范围、黄斑中心凹厚度、外界膜及内外节连接均可能影响视力的预后；

· CONCLUSION : The visual acuity in resolved CSC eyes was probably correlated with the amplitude of neurosensory detachment , the foveal thickness , the external limiting membrane and the boundary between the photoreceptor cell bodies and the outer segments .

不同的外界信号通过膜受体在膜内生成第二信使来进行跨膜信号转导的，都需要通过结构类似的各种G蛋白的介导。

Different external signals carried out transmembrane signal by generating second messengers transduction in the membrane , which all required a similar structure of the various G protein-mediated .
