Measured were the free erthrocyte protoporphyrin levels (a blood component) in 29 Ss with alpha thalassemia (a hereditary anemis), 19 Ss with iron deficiency anemia, and 24 normal control Ss. (DB)

Urinanalysis was performed on 24-hour samples of 11 iron deficient children (1 to 13 years of age) to determine levels of monoamine oxidase (an enzyme). (DB)

Serum of five children ages 1 to 19 months with congenital pure red cell aplasia (incomplete or defective development of red blood cells) was injected in normal mice to determine possible inhibition of red blood cell formulating stimulants. (CL)

In an attempt to improve the identification of the asymptomatic carrier of classic phenylketonuria (PKU) 59 male and female normal control Ss were differentiated from 18 males and females heterozgous for PKU. (DB)

Prenatal monitoring for metachromatic leukodystrophy (a fatal inherited metabolic disorder) suggested that the determination of levels of cerebroside sulfatase in the amniotic fluid helped in the prenatal detection of this disorder. (DB)

Investigated in 16 persons ages 3 to 23 years with severe cystic fibrosis was the absorption level of digoxin (a lipid soluble medication). (CL)

Nineteen of thirty-three children (5-to 18-years-old) whose arterial septal heart defects were surgically repaired did not undergo pre-operative cardiac catheterization. (CL)

Sequential urinalysis of four premature infants with marked physiologic anemia demonstrated no erythropoietin (substances which may stimulate red blood cell formulation). (CL)

Evaluated was retinal functioning of 15 4-year-old children who had received phototherapy for neonatal hyperbilirubinemia (jaundice). (DB)

Studied were the behavioral characteristics of 60 methadone addicted infants and 53 nonaddicted infants during the first year of life (neonatal period, and at 3, 6, and 12 months of age). (PT)
