If the body uptake is not prevented by alginates\/seaweeds the strontium is absorbed by the blood and deposited in the skeleton, where it may cause bone tumours or leukaemia. Alginates\/seaweeds can even be used to reduce strontium already deposited in the bone. It is supposed that some of this is released slowly, re-secreted, possibly through the bile, and then bound in the intestines by alginates\/seaweeds and excreted, if alginate treatment is given; otherwise it is re-absorbed by the blood. Thus alginate\/seaweed can serve both as a preventive and a therapeutic measure. The phycocolloids of red algae do not possess this property but algaes as laminaria, asco and fucus has this property. In addition to a high level of guluronate units fo the alginate a certain chain length ( 150 units polyguluronate) is essential for the highest biological activity. Suitable combinations could be looked for within the natural resources, or obtained through partial hydrolysis of \u00a0the alginates\/seaweeds.<\/p>\n","protected":false},"excerpt":{"rendered":"
