[Preparation of agar and agarose from the red algae Ahnfeltia tobuchiensis].

A simple and inexpensive procedure of agar and agarose production from the red alga Ahnfeltia tobuchiensis was developed, which needs no additional chromatographic purification.

[Functional properties of alginates and their use in therapeutic-prophylactic nutrition].

Adsorbability of alginic acid and its salts extracted from brown seaweeds and character of their biological action were studied. The results of clinical tests alginic acid and its salts as well as of preparations and food-stuffs, prepared from Laminaria japonica Arech, were reflected. The potentialities of use of alginates and food-stuffs containing them in therapeutic nutrition was shown.

[Effect of alginic acid and its salts on the dynamic of 85Sr and 137Cs accumulation in rats].

Accumulation of 85Sr and 137Cs radionuclide blend in rats was studied. Effect of alginic acid, its salts as well as foods containing the polysaccharides on dynamics of accumulation was established. It was shown that efficiency of compounds studied depends on type of salt of alginic acid and presence of guluronic acid in it.

[Evaluation of the use of sea products in nutrition of population inhabiting regions under rigid radiation control].

Noninbred female white rats were fed for 30 days with diets containing 137Cs and 85Sr in indicative doses. After that the animals received some sea products to investigate their radioprotective properties. Natural sea products proved able to influence the kinetics of the radionuclides metabolism.
