[Experimental rationale for approaches to the development and evaluation of new functional foodstuffs].

This comprehensive experimental study had the objective to determine the optimum ratio of calcium and vitamin D used as additives in food compositions and provide an experimentally-based rationale for the use of new functional dairy products and evaluation of their nutritional value. Experimental medico-biological assessment was conducted using growing male Wistar rats by balance and biochemical methods. It was shown that the calcium/vitamin D ratio in foodstuffs determines their functional efficiency. High nutritive and biological value was documented for some new cottage cheese products rich in calcium (240 mg%) and vitamin D (1 mg%). Results of the study were used to develop guidelines for the enrichment of various food compositions with calcium and vitamin D and substantiate methods for the assessment of their real functional effectiveness.

[Comparative evaluation of radiation protective efficiency of regimens with various content of calcium, potassium and iron]. / Sravnitelnaia otsenka radioprotektornoi éffectivnosti ratsionov s razlichnym soderzhaniem kaltsiia, kaliia i zheleza.

Calcium deficit in ration of rats considerable reduced radioprotective potential of animals. The enrichment of ration for calcium, potassium, and iron improved radioprotection by changing velocity of accumulation and excretion of cesium.

[Role of alimentary calcium in the prevention of intestinal microflora disorders during sensitization]. / Izuchenie roli alimentarnogo kaltsiia v profilaktike disbakterioza kishechnika v usloviiakh sensibilizatsii.

According to experimental data, shortage of calcium in diet of experimental animals in conditions of sensitization leads to disturbances in intestinal microflora. Consequently calcium is an important factor of organism adaptation to antigenic loading.
