血浆皮质醇90%以上与蛋白质(CBG)结合,不具生物活性,具生物活性的血浆游离皮质醇可随尿排出,称尿游离皮质醇。本文报告43名健康人尿游离皮质醇的放免测定及其昼夜变化。材料与方法材料:本组43名健康人,男18名,女25名;年龄19～55岁,平均28岁。试验在医院进行,分别于7:00～9:00,15:00～17:00,23:00～1:00留取2小时阶段尿(每次留尿前需排空膀胱),另对其中15名加留第二日7:00～9:00阶段尿,
More than 90% of plasma cortisol binds to protein (CBG) and is not bioactive. Biologically active plasma free cortisol is excreted with urine and is called urine free cortisol. This article reports 43 healthy people urinary free Cortisol radioimmunoassay and its diurnal changes. Materials and Methods Materials: The group of 43 healthy people, 18 males and 25 females; aged 19 to 55 years, mean 28 years old. The trial was conducted in the hospital. Urine was collected for 2 hours at 7:00 ~ 9:00, 15:00 ~ 17:00, 23:00 ~ 1:00 (emptying the bladder before each urination) Of which 15 were added on the second day 7: 00 ~ 9: 00 stage urine,
