[Criteria of supply of vitamins B1, B2, and B6 in children with insulin-dependent diabetes mellitus]. / Kriterii obespechennosti organizma detei, bol'nykh insulinzavisimym sakharnym diabetom, vitaminami B1, B2, i B6.

By mathematically analysing the curves of urinary excretion of vitamins, their plasma and erythrocytic concentrations or of TDP-effect, by constructing and mathematically interpreting the variation curves of distribution of a given plasma concentration of riboflavin and pyridoxal phosphate for 10-14-old-year children suffering from insulin-dependent diabetes mellitus after supplementation of vitamin, as a criterion of normal requirement for vitamin B2, the authors are prone to recommend the concentration of riboflavin over 10 micrograms/ml in plasma and over 96 micrograms/ml in erythrocytes, the hourly excretion of more than 27 micrograms. It has been ascertained that the criteria for the optimal body's requirements for vitamins in diabetes mellitus children do not differ from those in healthy age-matched children. Thus, the value of TDP-effect is less than 1.25, the concentration of pyridoxal phosphate is over 8.4 micrograms/ml plasma, the excretion values of thiamine and 4-pyridoxic acid are 13.5 and 64.0 micrograms/h, respectively.

[Effectiveness of the use of vitamin-enriched food premixes in the nutrition of children with insulin-dependent diabetes]. / Effektivnost' izpol'zovaniia obogashchennykh vitaminnymi premiksami gotovykh bliud v pitanii detei, bol'nykh insulinzhavisimym sakharnym diabetom.

Vitamin-deficient children suffering from diabetes mellitus received milk dishes and drinks enriched with vitamin-rich premixes produced in Austria (Roche) for 2 weeks. The diet efficacy was evaluated by the values of thiamine, riboflavin, 4-pyridoxic acid, 1-methylnicotinamide and xanthurenic acid urinary excretion, blood levels of free and total riboflavin, nicotinamide and pyridoxic coenzymes, transketolase activity measured before and after the diet treatment. The latter resulted in a marked improvement in the levels of vitamins B1, B2, B6, PP and C, prevented the spring fall in vitamin supply. In view of incomplete normalization of the children's vitamin status after the two-week diet it is recommended to use the vitamin-enriched food and drinks for longer time or under a continuous regimen.

[Consumption of basic foods, state of health and physical work capacity of middle school students]. / Potreblenie osnovnykh pishchevykh veshchestv, sostoianie zdorov'ia i fizicheskaia rabotosposobnost' uchashchikhsiia srednikh shkol.

Actual nutrition, health state and physical working capacity were studied in schoolchildren of three age groups after intake of the polyvitamin "Undevitum" during a month. The results of the investigation conducted have shown that prophylactic measures produced a positive effect on the schoolchildren aged from 11 to 13 and from 14 to 17 years who received 1 degree of "Undevitum" daily. No positive effect was recorded in schoolchildren aged 7-10 years who received 1 degree of "undevitum"/day, every other day.

[Some lipid metabolic indises in schoolchildren whose nutrition utilizes new products of increased biological value]. / Nekotorye pokazateli lipidnogo obmena u shkol'nikov pri ispol'zovanii v pitanii novykh produktov povyshennoi biologicheskoi tsennosti

Issues concerned with a more rational nutrition of schoolchildren working under an elevated mental stress are discussed. The fat and acid composition of the rations was corrected by inclusion of new fatty, dairy and sour milk products enriched with vegetable oil. Some characteristics of the lipids metabolism in the blood serum of practically healthy children of different age categories were studied. In children of senior school age lipids metabolism was analyzed in dynamics against the background of a successive application of food rations differing in the fat and acid composition. A different dependance of these characteristics on nutritional factors was ascertained.
