血清催乳素(简称PRL)测定对垂体肿瘤的诊断愈益重要。以往认为嫌色细胞无分泌颗粒,亦无激素分泌功能。如今电镜已证实嫌色细胞含有分泌颗粒,放射免疫测定的应用,使激素分泌腺瘤的发现明显增加。 多数作者从蝶鞍改变和血清PRL值的升高来推
Serum prolactin (PRL) determination of the diagnosis of pituitary tumors is increasingly important. In the past that chromophobe cell-free secreted particles, nor hormone secretion. Electron microscopy has now confirmed that chromophobe cells contain secreted particles, radioimmunoassay applications, so that the discovery of hormone-secreting adenoma was significantly increased. Most authors push from changes in sella and elevated serum PRL
