Abstract
THERE has been considerable medical interest in the ion exchange properties of alginates. Inhibition of the uptake of strontium by rats given doses of sodium alginate has been reported1–3 and there was a similar experiment with a human adult4. The absorption of calcium was not significantly affected. The results were considered to have potential value in connexion with therapy of overdoses of strontium-90 (ref. 5). The effect of two commercial alginates with different chemical compositions, that is, different ratios of mannuronic and guluronic acid residues in the alginate, on strontium uptake in rats was compared6. The alginate with the greater content of guluronic acid residues reduced the uptake of strontium from the diet more effectively.
