Selenium concentration and glutathione peroxidase activity in blood of New Zealand infants and children. 1978

R L McKenzie, and H M Rea, and C D Thomson, and M F Robinson

The blood selenium (Se) concentrations of New Zealand children were lower than those reported for children living in other countries. This low blood Se was primarily determined by the low dietary intake of the children which, in turn, reflects the low Se content of New Zealand soils. Blood Se also varied geographically, with age, and with differences in quantities and types of food eaten. Children with phenylketonuria and maple syrup urine disease on synthetic diets had low Se intakes and blood Se concentrations compared with children on normal diets, and blood Se was seen to decrease with the length of time on these diets. A strong correlation (r = 0.62, P less than 0.001) was found between the blood Se levels and glutathione peroxidase activities for 107 children. Glutathione peroxidase activities of the children were lower than activities observed in New Zealand adults, refelecting their lower blood Se concentrations.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D008375	Maple Syrup Urine Disease	An autosomal recessive inherited disorder with multiple forms of phenotypic expression, caused by a defect in the oxidative decarboxylation of branched-chain amino acids (AMINO ACIDS, BRANCHED-CHAIN). These metabolites accumulate in body fluids and render a "maple syrup" odor. The disease is divided into classic, intermediate, intermittent, and thiamine responsive subtypes. The classic form presents in the first week of life with ketoacidosis, hypoglycemia, emesis, neonatal seizures, and hypertonia. The intermediate and intermittent forms present in childhood or later with acute episodes of ataxia and vomiting.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009520	New Zealand	A group of islands in the southwest Pacific. Its capital is Wellington. It was discovered by the Dutch explorer Abel Tasman in 1642 and circumnavigated by Cook in 1769. Colonized in 1840 by the New Zealand Company, it became a British crown colony in 1840 until 1907 when colonial status was terminated. New Zealand is a partly anglicized form of the original Dutch name Nieuw Zeeland, new sea land, possibly with reference to the Dutch province of Zeeland.

D010544	Peroxidases		Ovoperoxidase
D010661	Phenylketonurias	A group of autosomal recessive disorders marked by a deficiency of the hepatic enzyme PHENYLALANINE HYDROXYLASE or less frequently by reduced activity of DIHYDROPTERIDINE REDUCTASE (i.e., atypical phenylketonuria). Classical phenylketonuria is caused by a severe deficiency of phenylalanine hydroxylase and presents in infancy with developmental delay; SEIZURES; skin HYPOPIGMENTATION; ECZEMA; and demyelination in the central nervous system. (From Adams et al., Principles of Neurology, 6th ed, p952).
