RT Journal Article SR Electronic T1 Excretion of polyamines by children with Beckwith's syndrome. JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 40 OP 42 DO 10.1136/adc.55.1.40 VO 55 IS 1 A1 G B Barlow YR 1980 UL http://adc.bmj.com/content/55/1/40.abstract AB The urinary excretion of the polyamines--putrescine, spermidine, and spermine--was measured in 7 children with Beckwith's syndrome. Putrescine excretion was raised and spermidine excretion reduced. The raised putrescine and the low spermidine ratios were highly significant. These results are consistent with a disturbance in a metabolic pathway under growth hormone-like regulation.
