Examined were medical records of 265 hyperkinetic children (7-9 years old). Clinical blood chemistries, hematology, and 5-hour glucose tolerance test (GTT) results indicated that hematocrit levels were low in 27% of the Ss, eosinophil levels were abnormally high in 86% of the Ss, and GTT results were abnormal in a maority of Ss. (CL)

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)

Minutiae, ends and junctions of finger tip or palm lines, were analyzed in a sample of 115 normal adult individuals, 40 cases of Down's syndrome, and 130 normal children (aged 6 to 14 years). (DB)

Reviewed are diagnostic tests of symphocyte subgroups which identify immuno deficiency disorders (such as DiGeorge's Syndrome) and malignant cells in lymphoproliferative disorders (such as lumphoid leukemia). (CL)
