THE PHOSPHATE PARTITION OF THE ERYTHROCYTES OF NORMAL NEWBORN INFANTS AND OF INFANTS WITH HEMOLYTIC DISEASE

Abstract
The phosphate partitioning of the erythrocytes of normal cord blood and blood of infants with hemolytic disease of the newborn differed in these respects: A higher level of easily hydrolyzable phosphate was found initially in the erythrocytes of infants with Anti-D hemolytic disease than in normal cord blood; after 14 days of storage at 4oC the inorganic P content increased and the easily hydrolyzable fraction decreased significantly more in the erythrocytes of infants with hemolytic disease than in the red cells of normal infants, p < .005. Significant differences were found between the phosphate partition of the erythrocytes of normal newborn infants and normal adults.
