Conjugated and free urinary oestrone and oestradiol-17 beta were determined by radioimmunoassay in 98 urine samples of 44 normal male and female infants ranging from 7 days to 2 years of age. Both sexes excreted significantly more oestrone and oestradiol-17 beta during the first 3 months of life compared to the end of the first year. Values peaked at the beginning of the second month. During the first 7 months of life, female infants excreted significantly more conjugated oestradiol-17 beta than oestrone, whereas male infants consistently excreted equal amounts of conjugated oestradiol-17 beta and oestrone. However, both sexes excreted significantly more free unconjugated oestrone than oestradiol-17 beta during the same period.
采用放射免疫分析法对44名年龄在7天至2岁之间的正常男、女婴幼儿的98份尿液样本中的结合型和游离型尿雌酮及雌二醇-17β进行了测定。与1岁末相比，两性在出生后的前3个月排出的雌酮和雌二醇-17β明显更多。数值在第二个月初达到峰值。在出生后的前7个月，女婴排出的结合型雌二醇-17β明显多于雌酮，而男婴排出的结合型雌二醇-17β和雌酮量始终相等。然而，在同一时期，两性排出的游离非结合型雌酮均明显多于雌二醇-17β。
