Serum `uracil + uridine' levels in normal subjects and their possible significance

AUTOR(ES)
RESUMO

A microbiological method for the assay of uracil is described. The growth of the test organism is supported by uracil and also by uridine but not by uridylic acid. The method therefore measures uracil and uridine together. The `uracil + uridine' level, expressed as uracil, has been measured in blood from 144 normal subjects ranging in age from cord blood to the eighth decade. The mean level of 22 μ mol/l (0·25 mg%) in cord blood decreases to 15 μmol/l (0·17 mg%) in adults over the age of 20. There is no difference between the sexes.
