title: [The vitamin allowance of the pupils in a rural vocational and technical school and their prophylactic vitaminization].
abstract: The actual nutrition and providing with vitamins C and B1 was studied in boys aged 16-17 years, students of a rural trade school (Volsk of Saratov Province). Although the caloric value of their ration was high enough the content of animal proteins was only 42-48 g/day. The content of ascorbic acid in the ration comprised 48%, in the spring of 1987 it was 17%, and of 1988-29% of the recommended standard, vitamin B1 levels did not show seasonal differences. Vitamin C and B1 deficiencies in the spring were proved by their low excretion levels in urine, and by a low concentration of vitamin C and decreased activity of B1-dependent enzyme transketolase in the blood. Intake of "Undevitum" (1 dragee/day) during 4 months was conductive to the improvement of the student providing with vitamins.
