评价正常人和某些病人血浆激素浓度变化的意义时,必须知道正常人激素浓度的年龄变化。作者对严格筛选的21～85岁的正常成人,测定了总睾酮,游离睾酮和去氢睾酮(DHT),雌酮,雌二醇,促卵泡激素(FSH)和促黄体激素(LH)的24小时平均血浆浓度。材料和方法对象 35名健康男性,年龄为21～85岁。所有对象均经严格挑选,除外了任何已知的或可疑的能使内分泌功能发生变化的医药因素。 24小时平均血浆激素浓度在24小时内,每20分钟采血一次,共得血标本72份,从中各取出等量血浆一份混合,然后测定混合血浆的激素浓度作为
When evaluating the significance of changes in plasma hormone concentrations in normal individuals and in some patients, it is important to know the age-related changes in hormone concentrations in normal individuals. The authors tested the levels of total testosterone, free testosterone, and dehydrotestosterone (DHT), estrone, estradiol, follicle stimulating hormone (FSH), and luteinizing hormone (LH) in healthy adults 21 to 85 years old Hourly mean plasma concentration. Materials and Methods Subjects 35 healthy men, aged 21 to 85 years old. All subjects are carefully selected, except for any known or suspicious medical factors that can change the endocrine function. 24-hour average plasma hormone concentration within 24 hours, every 20 minutes blood sampling, a total of 72 blood samples were taken from each of the same amount of plasma was taken out of a mixture, and then determine the mixed plasma hormone concentration as a
