Desmosines from 24 h human urine samples were isolated, characterized and quantified. The desmosines are in peptidyl form (1000--1500 molecular weight), and their amount is decreased by two-thirds between 7 and 25 years of age. Patients with Marfan's syndrome have significantly lower urinary amounts of desmosines than do comparable controls during the early development period.
从24小时的人类尿液样本中分离、鉴定并定量了异锁链素。异锁链素呈肽基形式(分子量为1000 - 1500),其含量在7至25岁之间减少了三分之二。在早期发育阶段,马凡氏综合征患者尿液中的异锁链素含量显著低于相应的对照组。
