查询词典 Lens

Little is known about the mechanism of translocation of macromolecules into lens epithelium and fiber cells. The study was to observe whether the rupture of zonule affected translocation of macromolecules into the lens and to determine the role of zonule in transferring these macromolecules.

大分子物质晶状体内转运的机制目前还不十分清楚，本研究的目的是观察悬韧带离断对大分子物质晶状体内转运的影响，以探讨悬韧带在大分子物质转运中的作用；3。

During cataract surgery, when counter with rupture of lens posterior capsular, deletion and extension of the zonule in ICCE, ECCE, PHACO and SICS, the ideal way is in-the-bag implantation and scleral suture fixation of posterior chamber intraocular lens.

白内障摘除手术中，不管采用ICCE、ECCE、超声乳化及小切口法等遇到晶体后囊膜破损、缺失或悬韧带断离等采用囊袋内植入和睫状沟巩膜瓣下缝线固定法应是术者较理想的首选。

It also has lens shift and a longer 2.0:1 zoom lens.

RESULTS: In the process of VEP optometry, 75 ametropic eyes were corrected through spherical lens, while 52 ametropic eyes were corrected by cylinder lens.

为了分析VEP验光结果的准确性及应用价值，对比其与目前常用的电脑验光方法之间是否存在差异，我们对50例86眼依次行电脑验光和VEP验光，对各项结果进行比较分析。

The results shown that:(1) Bufo raddei Strauch tadpole was capable of lens regeneration, which originated from the epithelial cells at dorsal iris margin by depigmentation.(2) Depigmentation of Bufo raddei Strauch during lens regeneration was by two methods: First, pigment granules initially dispersed all over the cytoplasm were moved towards the periphery of the cell, and then were directly taken up by the amoeboid cells. Second, pigment granules in a cell were first crowded in a mass, surrounded by a membranous structure in the cytoplasm, which were eventually discharged as a mass from the cell.

结果表明：花背蟾蜍蝌蚪(1)具有晶状体再生的能力，其晶状体的再生来源于虹膜背缘的上皮细胞；(2)虹膜背缘去色素是转分化的前提，主要有两种方式：一种也是最主要的方式是在晶状体被摘除后虹膜外侧产生巨噬细胞，巨噬细胞吞噬虹膜色素上皮细胞中的色素颗粒；另一种方式是虹膜色素上皮细胞自身释放色素颗粒；(3)电镜观察发现虹膜色素上皮细胞转分化过程中线粒体有明显变化，核糖体增多，粗面内质网增多，晶状体纤维分化过程中细胞核逐渐凝聚。

The apparatus includes an optical fiber biconic lens disposed on an end of the optical fiber such that the optical fiber and the biconic lens define an optical axis.

该装置包括一个定位在光纤(44)一端上的光纤双锥形透镜(46)，使得光纤和双锥形透镜限定光轴。

Methods Transmission electron microscope was used to observe the apoptotic morphology of the lens epithelial cells in 4 cases with senile cataract and in 2 mice with congenital cataract. The comparisons were made between the cataractous and normal transparent lens epithelial cells in human being and mice.

用透射电镜观察4例老年性白内障患者及2例先天性白内障小鼠晶状体上皮细胞凋亡的超微结构，并分别与同类正常晶状体上皮细胞超微结构进行比较。

The C18 known sequence, whose sequence had been known but function remained unknown, was expressed in cataractous lens epithelium but was not expressed in normal lens epithelium.

序列已知而功能未知的C18已知序列在白内障晶状体上皮有表达，但其在正常晶状体上皮中无表达。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.
