对23例人胚鼻咽上皮原代培养细胞进行了酸性酯酶(ANAE)、乳酸脱氢酶(LDH)和β-葡萄糖醛酸酶(β-GA)等三种酶组织化学研究,发现培养的上皮细胞有一定的ANAE和LDH的活性,β-GA活性很弱或不能显示;ANAE反应产物弥散分布于整个胞浆中;LDH反应产物主要集中在核膜附近的胞浆中,多核巨细胞的 LDH 反应产物则满布整个胞浆。 Thirty-three human nasopharyngeal epithelial primary cultured cells were subjected to histochemical studies of three enzymes, namely, acid esterase (ANAE), lactate dehydrogenase (LDH), and β-glucuronidase (β-GA) Of the epithelial cells have certain ANAE and LDH activity, β-GA activity is weak or can not be displayed; ANAE reaction products dispersed throughout the cytoplasm; LDH reaction products mainly in the nuclear membrane near the cytoplasm, multinucleated giant cells Of LDH reaction products are full of the entire cytoplasm.
