RESUMO
The nutrition, particularly provision of antisclerotic and antioxidant nutrients, has been studied for population of radiation-controlled territories, personnel of nuclear power stations, radiation-exposed inpatients. Nutritional deficiency was stated in relation to vitamins A, C, E B-carotine, sulfur-containing amino acids. Imbalance was found in fat and carbohydrate rations. It is thought valid to conduct relevant corrective changes in nutrition of the studied groups of population.

Effect of natural and enriched with pectin tanned fruits on radiation-induced metabolic disorders was studied in persons subjected to radiation due to Chernobyl accident. It was shown that products in question beneficially influenced blood antioxidant system as well as brought to the norm contents of triglicerides and albumins in patients with IIa and IV types of hyperlipoproteinaemia.

Some indices of free radical processes and antioxidant blood protection systems were investigated in a group of persons exposed to ionizing radiation at the Chernobyl accident. Lipid peroxidation was shown to undergo changes against a background of decreased antiperoxide protection of erythrocytes 22-24 mos. after exposure in patients after acute radiation sickness, I degree. As compared to donors, the examinees demonstrated a tendency to the accumulation of primary products of lipid peroxidation--hydroperoxides (by 32.2%) and a significant decrease in erythrocyte peroxide stability.

In a group of similar subjects correlation has been revealed between the level of protein intake and nitrogen indices of urine assayed in the portion of urine taken on an empty stomach. The nitrogen indices of urine: creatinine N/total N, creatinine N/urea N, creatinine N/amine N, urea N/total N proved to be the most informative criteria of protein nutrition. It was found that the indices studied could be used as signs of providing the group of subjects with protein and for prognosing the protein nutrition level by the simulation of linear regression, using the methods of the random process theory.

Energy losses, actual nutrition work fitness and metabolism were examined in 309 operators. It was found that energy losses in the operators were equal to 2724 kcal, while energy requirements did not exceed 3000 kcal/day. Actual nutrition of the test subjects was not adequate as regards the consumption of animal proteins, vegetable oils, vitamins A and C. Control panel operation produced marked shifts in the function of the central nervous system and cardiovascular apparatus of the operators. Disorders of lipid and vitamin C metabolism were also recorded.
