Vitamin status of workers in steel-smelting departments of the Karaganda Metallurgy Plant]

The author investigated the vitamin status of workers engaged in steel-smelting at the Karaganda Metallurgy Plant. It was found that the workers of the main occupational groups at the plant were insufficiently provided with vitamins A, C and B due to their low content in the food. The system of medico-prophylactic vitamin administration used for steel workers is ineffective.     

Vitamin status of workers in the chromium industry

The content of A, E, C, B2 and PP vitamins and their metabolites in the blood and urine as well as microsigns of vitamin deficiency were studied in workers engaged in chrome industry. Microsigns of vitamin deficiency were observed along with low levels of vitamins. This appears to be associated with increased physiological requirements in vitamins due to specific work of chrome industry personnel.     

Prevention of combined iron-polyvitamin deficiency in female workers in the machine-building industry]

The results have been presented of the study of ferrokinetic values and providing with ascorbic and folic acids, vitamins B2 and B12 in women with latent iron deficiency, before and after preventive measures with the use of the lactic acid product "Biolact" combined with the polyvitamin "Gendevitum". The data obtained have shown that latent iron deficiency is attended by vitamin deficiency. "Biolact" enriched with iron and ascorbic acid, combined with "Gendevitum" normalizes iron metabolism and vitamin providing.     

The vitamin status and indices of immunity in workers in the metallurgical industry in Zapoliar'e]

Some parameters of vitamin providing and immune status were studied in 133 workers and employees of metallurgic industry in Zapolyarie. The data obtained have evidenced that the contingent studied was insufficiently provided with ascorbic acid, vitamins B1, B2, B6, had low content of vitamin A and beta-carotene. Combined vitamin deficiency was recorded in 88.6% of 44 workers subjected to investigations. A total of 87.7% of persons with low vitamin levels had shifts in the immunity system. The highest disorders in the cellular immunity parameters were observed in subjects with polyhypovitaminosis. The results of the study have necessitated taking measures for correction of vitamin providing.     

Vitamin allowance of workers engaged in the manufacture of phosphorus

The clinical trials of a new treatment and prophylactic diet at the Chimkent phosphorus plant have shown its high efficacy as compared to an old one. This was manifested in the improvement of the workers supply with retinol, tocopherol, ascorbic and nicotinic acids. The treatment and prophylactic diet produced a more efficacious action on the vitamin supply when being a constituent part of the corrected daily nutrition that of the factual nutrition.     

Hygienic training of the workers occupied in food industry

The system of professional hygienic training for the workers of enterprises in various branches of food industry needs updating. Suggestions how to improve this work are made.

An improvement in the hygienic instruction of workers in dairy industry enterprises

The article presents the experience of the work on the sanitary education of the workers of the milk industry plants in Moscow and Moscow Province. The Institute's specialists had worked out basing on the studied experience the program of the full-time and external differential sanitary education of the workers of the milk industry which was approved by the Department of the State Sanitary Control of the Ministry of Health of Russia the April 22, 1998. "An exercise book for the sanitary education of the workers of the milk industry plants" was also prepared and published in 1999.     

Vitamin D and calcium metabolism in relation to different levels of vitamins B6 and D]

The influence of vitamin B6 deficiency on some vitamin D-dependent processes was studied in animals. The following parameters changing in relation to the level of vitamin D providing were investigated: activity of alkaline phosphatase in the serum and small intestine mucosa, the levels of Ca, P and parathormone, concentration of vitamin D metabolites and enzyme activity; and only 25-hydroxyvitamin D (25-OVD) concentration in the blood serum, under conditions of combined vitamin B6 and D deficiency was significantly lower as compared to cases with vitamin D deficiency alone. In the presence of vitamin B6 deficiency recovery of 25-OVD level in the blood serum, after vitamin D administration to the animals, had a tendency to delay as compared to that in the animals provided with vitamin B6. Vitamin B6 deficiency produced similar effect on 25-OVD 1-hydroxylase activity. The data obtained have evidenced a possibility of vitamin B6 influence on vitamin D metabolism.     

Vitamin levels in children with latent iron deficiency

Providing with ascorbic acid, vitamins A and E, thiamine, riboflavin and pyridoxine was biochemically investigated in 108 children aged from 9 to 15 years. Significant disorders in the providing with all these vitamins were observed, the highest deficiency of ascorbic acid and pyridoxine being recorded. Vitamin deficiency in children was expressed as polyhypovitaminosis. Children with latent iron deficiency are less provided with vitamins than normal children, and the incidence of this or that vitamin deficiency in them is higher. The data obtained have evidenced that normalization of the body providing with vitamins should play an important role in the preventive treatment of children with latent iron deficiency.     

Vitamin C stability in vitamin-fortified syrups]

Factors influencing ascorbic acid stability in syrups were studied. It has been found that the vitamin stability depends on its concentration and the syrup composition. It is shown that vitamin C stability can be increased in some syrups by substitution of ascorbic acid for sodium ascorbinate.     

Characteristics of lipid metabolic indices of food industry workers

Irrational diet is among the risk factors of the development of lipid metabolism abnormalities and associated disorders of the cardiovascular system. To prevent these conditions, it is necessary to be aware of the content of individual lipids in the blood serum and to study the mechanisms of their changes. Lipid metabolism was explored in the workers engaged in food industry of the city of Vilnius in terms of the relationship to such factors as age, sex, body weight, relative weight of the fatty, osseous and muscle tissues. It has been demonstrated that the content of cholesterol esters and triglycerides in the blood serum appeared helpful in finding differences between the workers' groups from different factories. Lipid metabolism was also investigated by means of correlation and regression analysis.
