    Description / Table of Contents: Zusammenfassung Die Aktivität des Selenenzyms Glutathionperoxidase (EC 1.11.1.9) wurde in den Blutplättchen von 15 Patienten mit frischem Herzinfarkt und 13 Kontrollpersonen gemessen. Die Blutplättchen der Patienten zeigten signifikant niedrigere Enzymaktivitäten (P(t)〉0.99). Möglicherweise steht dies mit der Erkrankung in pathogenetischem Zusammenhang.
    Notes: Summary The activity of the selenoenzyme glutathione peroxidase (EC 1.11.1.9) was determined in platelets of 15 patients with acute myocardial infarction and 13 control subjects. The platelets of the patients had significantly lower activities of the enzyme (P(t)〉0.99). This may be related to the pathogenesis of the disease.

    Notes: Abstract Hair selenium content was estimated by instrumental neutron activation analysis in Libyan infants and children. There was no significant difference between the values of young infants from North and South Libya. The hair selenium content rapidly decreased from 1071 ±75 ng/g in newborns to 301±99 ng/g in 7–10 months old infants in North Libya and to 557±204 ng/g in South Libya. In North Libya the values of preschool children were 409±117 ng/g and those of school children 464±124 ng/g.

    Selenium requirements in patients with inborn errors of amino acid metabolism and selenium deficiency (1980)
    Springer

    Notes: Abstract The diets of 5 patients with phenylketonuria or maple-syrup-urine disease were supplemented with yeast which was rich in selenium. For 120 days the patients received 45 μg Se/day to increase the Se content of their diets to 10–12ng Se/Kjoule. Before supplementation the selenium content of serum (5–15 ng/ml) and whole blood (10–27 ng/ml), and the activity of the erythrocyte glutathione peroxidase (0.19–2.69 U37/g Hb), amounted to only 10–20% of normal. The serum selenium content reached normal values within 4 weeks of supplementation, followed by normalisation of the selenium content of whole blood within 4–8 weeks. Restoration of the activity of erythrocyte glutathione peroxidase took 9 to 15 weeks —the red cell life span. There was a significant positive correlation between the selenium content of the erythrocytes and the activity of erythrocyte glutathione peroxidase.

    Selenium intake of infants and young children, healthy children and dietetically treated patients with phenylketonuria (1984)

    Notes: Abstract In 20 healthy infants and children, 5–20 months old, the Se intake was estimated by analysing food samples by instrumental neutron activation analysis. The intake was calculated by weighing the portions offered and actually consumed. The median Se content of the food amounted to 27 ng/g wet weight (gww) and median daily Se intake to 33.5 μg. The Se intake was not equally distributed over the day. About 50% of the daily Se intake was derived from the supper. The main Se sources (41%) for young children were cereal paps. Commercially, available meals (30 ng/g) contained less Se than home-made ones (50 ng/g). In nine dietetically treated patients with phenylketonuria the median Se intake amounted only to 6.9 μg/day corresponding to a mean Se content of the diet of 7.9 ng/g. The main Se source in the diet was vegetables (36.3%) and 20% derived from their protein supplements. The Se intake of young children, healthy or dietetically treated, cannot be calculated accurately from tables but must be estimated by measuring the Se content of the local food because cereals and vegetables-the main Se sources-exhibit great regional variations.

    Description / Table of Contents: Zusammenfassung Der Haarzinkgehalt wurde in Haaren von Kindern aus Nord- und Südlibyen bestimmt. Der Zinkgehalt betrug 213±36 μg/g bei libyschen Neugeborenen. Es bestand kein Unterschied zwischen den Werten von Neugeborenen aus Nord- und Südlibyen. Der Zinkgehalt fällt während der Säuglingszeit ab. Bei Klein- und Schulkindern lag der Zinkgehalt bei 88±35 μg/g bzw. 89±25 μg/g. Diese Werte sind so niedrig wie die bei amerikanischen kleinwüchsigen Kindern oder fast so niedrig wie bei den ägyptischen und persischen Zwergen mit vermindertem Zincstatus.
    Notes: Summary Hair zinc has been investigated in children of North and South Libya. The hair zinc content amounts to 213±36 μg/g in newborns. There is no difference between the values of newborns from North Libya and newborns from South Libya. The hair zinc values decrease during infancy. In toddlers and school-children the hair zinc content is 88±35 μg/g, 89±25 μg/g resp. These values are as low as those reported in American children with low height percentiles or nearly as low as those found in dwarfs with poor zinc status from Egypt and Iran.

    The selenium content of infant food (1984)

    Description / Table of Contents: Zusammenfassung Der Selengehalt der Nahrung weist große regionale Unterschiede auf. Nahrungsproben von Säuglings- und Kleinkinderkost aus Nordrhein-Westfalen wurden mit Hilfe der instrumentellen Neutronenaktivierungsanalyse untersucht und zeigten, daß der Selengehalt der hiesigen Gemüse und Früchte durchschnittlich etwa 5 ng/g beträgt. Nur Proben von Kartoffeln und Bananen weisen einen höheren Selengehalt auf. Bananen, importiert aus verschiedenen Gebieten der Erde, zeigen eine extrem hohe Schwankungsbreite mit Werten zwischen 4 und 164 ng Se/g. Fertiggerichte für Säuglinge und Kleinkinder haben einen der Kuhmilch vergleichbar niedrigen Selengehalt von durchschnittlich 24 ng/g. Außer Eiern enthalten nur Milchbreie und einige andere getreidehaltige Produkte mehr als 100 ng Se/g.
    Notes: Summary The selenium content of food exhibits great regional differences. Food samples of infants and young children from the North Rhine-Westphalia State in the Fed. Rep. of Germany were analysed by instrumental neutron activation analysis and showed that the average selenium content of local vegetable and fruit is below 5 ng/g wet weight. Only samples of potatoes and bananas exhibit higher selenium contents. The bananas, probably imported from different areas of the world, show an extremely high variance with values between 4 and 164 ng Se/g. Commercially available ready-for-use meals for infants or young children have a low Se content (median 24 ng/g) which is comparable to cow's milk. Besides eggs, cereals enriched with milk and some other cereal products contain more than 100 ng Se/g.
