晶体囊和囊下上皮的超微结构——胎儿及成人晶体透射电镜和扫描电镜观察
Ultrastructure of Human Fetus and Adult Lens Capsule and Subcapsular Epithelium——A Scanning and Transmission Electron Microscopic Study
【摘要】 对胎儿、正常成人晶体囊和囊下上皮进行透射电镜和扫描电镜观察。晶体囊由细纤维状结构组成,表层疏松,深层较致密,二者无截然界限,未看到光镜下的两层结构。成人晶体囊的结构型式不随年龄增长而发生变化。18~65岁赤道前部及赤道部的晶体囊内有包涵物形成。在赤道部晶体囊的浅层看到插入的悬韧带纤维。晶体前囊下及赤道前部上皮细胞内见到纤毛。
【Abstract】 The capsule and subcapsular epithelium of 18 cases of fetuses and 28 cases of adult human lenses were studied by means of scanning and transmission electron microscopy. The capsule of the lens is loose in its superficial part and is dense in deep part, but no distinct demarcation line was found between the two parts. The two layers seen in light microscopy with aniline blue staining were not distinguished in electron microscopy. The structural form of adult lens capsule does not change with aging. Granular or fibriIlar inclusions were found in eqatorial and preeqatorial region of the capsule from 18 to 65. Inserted suspensary ligament fibers were seen in the superficial layers in the eqatorial region in adult lenses. Cilia were found in anterior and eqatorial subcapsular epithelial cells.
