Capillary whole blood selenium determination in assessing selenium status of children.

Selenium levels in venous and capillary whole blood of children were assessed by direct graphite furnace atomic absorption spectrometry. Selenium data obtained for both blood samples did not differ statistically (p > 0.05).

The mineral and trace element composition in French food items and intake levels in France.

A table was made of the composition of mineral and trace elements in different classes of French food items. The P, Ca, Mg, Fe, Cu, Zn, Mn, I and Se contents of the main categories of food are presented. The mineral and trace element intakes of the average French consumer were calculated from national survey data concerning all food items purchased by households.

Thiotungstate-copper interactions II. The effects of tetrathiotungstate on systemic copper metabolism in normal and copper-treated rats.

The intraperitoneal administration of tetrathiotungstate to rats (6-17.4 mg W/Kg BW) caused profound changes in copper metabolism in both normal rats and in rats pretreated with copper. Plasma copper associated with albumin increased, liver copper, particularly cytosol copper, was depleted, and biliary excretion was increased.

Thiotungstate-copper interactions. I. Studies on the metabolism of [185W] tetrathiotungstate and the systemic interactions of labeled pharmacological doses with copper in rats.

[185W] tetrathiotungstate was employed to study the metabolism of thiocompounds in rats after i.v. injection.

A simple system for nutritional studies with chronic consumption of liquid diet in rats.

A feeding system allowing liquid diet distribution to rats without any loss by evaporation is described. A liquid diet stirred continuously is offered to rats in water bottles. The diet is made available to the animals without any clotting throughout the 24-h period.
