测定24小时尿中考地松含量判断垂体—肾上腺功能比测定其代谢产物17—羟和17—酮可靠。但收集大量尿既麻烦又不易准确,往往需要在住院条件下进行。本文根据正常人考地松分泌在5～10时最高、22～4时最低这一昼夜节律,设计一种新方案即测定7～8和22～23时尿专地松含量,旨在简化程序,提高试验精度。 Determining the content of Phthalorsulfuron in urine in 24 hours was more reliable than determining the metabolites 17-hydroxy and 17-keto-pituitary-adrenal function. However, collecting large amounts of urine is both cumbersome and difficult to diagnose and often requires hospitalization. Based on the circadian rhythm of Pinus caespitso excreted at the highest level from 5 to 10 and the lowest from 22 to 4 in this paper, a new protocol was designed to measure the content of urine of 7 to 8 and 22 to 23 urils in order to simplify the procedure, Improve test accuracy
