Abstract
The mean whole blood selenium concentration in 12 patients on parenteral nutrition 0.045 +- 0.018 μg/ml, was considerably lower (P<0.001) than in normal New Zealand adult subjects (0.068 +- 0.013 μg/ml). The mean concentration of selenium in red cells (0.063 +- 0.018 μg/ml) was a little lower than values obtained in normal subjects, while the mean concentration of selenium in plasma (0.025 +- 0.012 μg/ml) was much lower than that found in 10 normal subjects (0.051 +- 0.009 μg/ml).
