Luteinizing hormone (LH) and LH-releasing hormone (LHRH) were measured by radioimmunoassay in blood samples collected from the pituitary gland during transsphenoidal surgery in 19 patients. Detectable levels of LHRH were present in 12 patients. Wide fluctuations of LHRH were seen in sequential samples collected at 10-minute intervals, suggesting a pulsatile mode of release. This technique may yield useful data on hypothalamic control of pituitary secretion.
采用放射免疫分析法对19例经蝶窦手术患者垂体采集的血样中的促黄体生成素(LH)和促黄体生成素释放激素(LHRH)进行了检测。12例患者血样中可检测到LHRH。每隔10分钟采集的连续样本中LHRH出现大幅波动,提示其释放呈脉冲模式。该技术可能会产生有关下丘脑对垂体分泌控制的有用数据。
