Supply of the main and doubling crews of cosmonauts with vitamins C, A, D, E, B1, B2, B6, PP, and B12, folic acid and carotinoids was studied during training and after the completion of short-term space flights (from 4 to 13 days). As the result of the investigation conducted during the intensive training, 1 month before the space flight some cases of certain vitamins deficiency were revealed. Administration of additional vitamins during 2 weeks before the flight led to a rise in the cosmonauts' supply with vitamins. The findings obtained after the short-term space flights evidence an intensive metabolization of vitamins and increased vitamin requirements during this period.

Materials derived from a study on the allowances of the organism of the physical culture institutes students of different sporting specialties (wrestling, cycling, light athletics, heavy athletics) of individual vitamins (A, B1, B2, B6, PP, C) and also results of investigations of the diurnal excretion with urine in them of sodium, potassium, as well as the catecholamines metabolism rates (epinephrine, norepinephrine, DOPA and dopamine) are presented.

[Vitamin supply of premature infants with intracranial birth injuries fed in different ways].

A total of 136 premature infants with intracranial birth trauma were studied during the first 2 months of life for vitamin B, C, A and carotinoid supply with regard to their body mass at birth and type of feeding. Premature children with different patterns of birth trauma showed low supply with thiamine, riboflavin, niacin and vitamin A in the presence of breast feeding. Combined feeding raised the supply of the children under observation with thiamine and riboflavin. The data obtained attest to the necessity of further study in this direction with the purpose of developing pathogenetically validated schemes for vitamin therapy of premature children.

[Vitamin status of diamond cutters].

Workers engaged in industrial treatment of diamonds manifested deficient supply of ascorbic acid, thiamine, riboflavin, pyridoxine and niacin in spring and autumn. This was ascertained on the basis of studying actual nutrition and specific indicators of the content of vitamins or their catabolites in the urine and blood and determination of metabolic functions of some vitamin-dependent enzymes.

[Vitamin status of premature infants in the 1st 2 months of life on natural feeding].

Fifty premature neonates were followed during the first 2 months of life to study the supply of the body with vitamins A, B6, ascorbic acid, riboflavin, thiamine, niacin and carotenoids with regard to the body weight upon birth and prematurity grade. The children were kept on natural feeding (donor's breast milk). Premature neonates were found to be short of individual vitamins during certain periods of life. The data obtained indicate that it is desirable to prevent vitamin deficiency by additional vitaminization with regard to the body weight upon birth and prematurity grade.
