[Effect of dietary correction and administration of multivitamin preparations on providing rural technical school students with vitamin C and B 1].
Actual nutrition and providing with vitamins C and B1 were studied in students of rural trade school (youths aged 16-17 years) in the town of Volsk, the Saratov region. The actual nutrition was corrected by inclusion of curds and other milk and vegetable products into the ration. The content of ascorbic acid in the usual and corrected rations, estimated analytically, during spring comprised 17 and 29%, and vitamin B1--49 and 75% of the recommended standard. The insufficient providing of the students with vitamins C and B1 in spring was confirmed by their low level of excretion with urine, and by lowered vitamin C concentration and activity of vitamin B1-dependent enzyme transketolase in the blood of the investigated students. The ration correction improved to a certain extent the values of providing with vitamins C and B1 but could not eliminate vitamin deficiency. Administration of "Undevitum" in a dose of 1 dragee/day during 4 months eliminated the vitamin deficiency in the ration and provided optimum vitamin levels for the students.
