Histopathelogical study of DAF on inner ear

加速衰变因子（DAF）是一种存在于许多哺乳动物细胞膜中的糖蛋白。DAF分子量为70kDa，通过糖基磷脂酰肌醇锚点插入膜中。在阵发性夜间血红蛋白尿。DAF在红细胞膜中缺乏，这使得它们更容易溶解。本研究的目的是确定在内耳中也可以检测到DAF。我们用体重约350g的正常雄性豚鼠研究DAF内耳的定位。内耳组织形态的DAF观察如下：1。血管纹（边缘细胞，中间细胞）内淋巴囊上皮细胞。未观察到DAF如下：1。corti的翻译结果：Reisseners膜耳蜗神经，耳蜗神经节细胞

Decay-accelarating factor (DAF) is a glycoprotein in the membranes of many mammalian cells. DAF has a molecular weight of 70kDa and is inserted into membranes by a glycosylphosphatidylinositol anchor.In paroxysmal nocturnal haemoglobinuria. DAF is deficient in erythrocyte membranes, which renders them more susceptible to lysis. The purpose of this study was to determine of DAF can also be detected in inner ear. We studied the localization of DAF inner ear, using normal male guinea pigs of about 350g body weight. DAF in inner ear tissue morphology was observed as follow, 1. stria vascularis (marginal cell, intermediate cell) 2. epithelial cell in endolymphatic sac.DAF was not observed as follows, 1. organ of corti 2. Reisseners membrane 3. cochlear nerve, cochlear ganglion cell.
