作者们用耳蜗铺片法制成标本,用硝酸银染色后在光学显微镜下观察前庭膜(Reissner氏膜)的细胞结构。标本取自死后10小时内的尸体,共20例(40耳),年龄在1～90岁之间,这些人都没有中、内耳病史,亦无长期使用耳毒性药物史。前庭膜从蜗底到蜗尖的长度,在5例为31.82～35.04mm,平均为34.02mm,宽度为0.65mm～0.75mm,平均为0.72mm,其外淋巴侧由一层薄的单层间皮细胞构成,该细胞形扁而长,沿长轴放射状排列,稍倾向蜗尖,靠近耳蜗底变为大的扁平细胞,呈多角形。间皮细胞通常较上皮细胞大5～10倍,核为卵圆形或梭形,位于细胞中心,比上皮细胞核大数倍。前庭膜之上皮层比间皮层复杂且不规则,用硝酸银染色时,较大的细胞边缘清楚而较小的细胞则较模糊,核小而圆,染色深。在婴儿上皮细 The authors used cochlear profiling to make specimens that were stained with silver nitrate to observe the cell structure of the vestibular membrane (Reissner’s membrane) under a light microscope. The specimens were taken from dead bodies within 10 hours after the death, a total of 20 cases (40 ears) aged from 1 to 90 years old. None of these people had a history of internal and internal ear disease and no history of ototoxicity was observed. The length of the vestibular membrane from the cochlear to the cochlea was 31.82 ~ 35.04mm in 5 cases, with an average of 34.02mm and a width of 0.65mm ~ 0.75mm with an average of 0.72mm. The outer lymphatic wall consisted of a thin single layer The skin cells, which are flat and long, are radially arranged along the long axis, slightly leaning toward the tip of the toe, and turn into large, flattened cells near the bottom of the cochlea with polygons. Mesothelial cells are usually 5 to 10 times larger than epithelial cells, nucleus oval or fusiform, located in the center of the cell, several times larger than the epithelial cell nucleus. The vestibular membrane epithelium is more complex and irregular than the mesothelial layer. When silver nitrate is stained, the larger cells are clear and the smaller ones are hazy, the nucleus is small and round, and the staining is dark. Thin baby in the epithelium
