[Effect of vitamin beverages on vitamin sufficiency of the workers of Pskov Hydroelectric Power-Plant].

The research of influence of vitamin complexes in the form of a drink or kissel on vitamin sufficiency of working persons has been carried out. Long inclusion (6,5 months) in a diet of vitamin drinks containing about 80% from recommended daily consumption of vitamins, was accompanied by trustworthy improvement of vitamins C and B6 sufficiency and prevention of seasonal deterioration of beta-carotene status. As initially surveyed have been well provided with vitamins A and E, their blood serum level increase had not occurred.

[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.

[Vitamin status in newborns of healthy mothers and of mothers suffering from hypertensive disease]. / Vitaminnyi status novorozhdennykh ot zdorovykh i stradaiushchikh gipertonicheskoi bolezn'iu materei.

The vitamin providing of the new-born children from the healthy mothers and from those with hypertonia of stages I-II has been investigated by the blood parameters and excretion of vitamins and their metabolites with urine. No principle differences were found between the both groups indices. The insufficient provision with thiamine, riboflavine and pyridoxine was revealed in 20-80% and deep deficit of thiamine in 40-60%. of the new-born children. Data obtained confirm a necessity to regulate taking B vitamins during pregnancy.
