Conditions for the determination of the fasting urinary hydroxyproline: creatinine ratio (OHPr: Cr ratio) have been examined, using a resin-catalysed hydrolysis and automated colorimetric procedure for the determination of hydroxyproline. Feeding experiments with gelatin showed that hydroxyproline is rapidly absorbed and excreted in the urine and that a 12-hour (overnight) fast is sufficient to ensure correct and reproducible fasting OHPr: Cr ratios. The mean fasting OHPr: Cr ratio decreased slightly with increasing age in both men and premenopausal women but there was no significant difference between the sexes. There was, however, a significant increase in the mean ratio in postmenopausal women. The normal range of fasting OHPr: Cr ratios for men and premenopausal women was found to be 0.003--0.015.
肌酐比值(OHPr:Cr比值)的条件进行了研究,采用树脂催化水解和自动比色法测定羟脯氨酸。用明胶进行的喂养实验表明,羟脯氨酸能迅速被吸收并经尿液排出,且禁食12小时(过夜)足以确保获得正确且可重复的空腹OHPr:Cr比值。男性和绝经前女性的空腹OHPr:Cr比值平均值均随年龄增长略有下降,但两性之间无显著差异。然而,绝经后女性的平均比值有显著升高。男性和绝经前女性空腹OHPr:Cr比值的正常范围为0.003--0.015。
