[Biologically active food additives: their role in human body sanitation and in prophylaxis of alimentary-dependent diseases].

The different aspects of the problem of health maintaining and strengthening are discussed. The special attention is devoted to the problem of diet that at present is characterized by deficiency of macro- and micronutrients. It is supposed that this factor together with the change in ecological condition promotes the development of different somatic diseases and their atypical course. To correct the dietary regimen, to strengthen the body functional reserves and to improve its nonspecific resistance to the influence of environmental unfavorable and pathogenic factors the possibility of wide use of biologically active food additives (BAA) is discussed. The examples of BAAs based on plant materials and results of their use in health resort conditions are given.

Is daily mvi required in patients receiving parenteral nutrition?

Between November 1996 and January 1999 there was a nationwide shortage of intravenous multivitamins (MVI) in the US. We investigated whether patients who received parenteral nutrition (PN) with MVI three times per week instead of daily developed clinical manifestations of vitamin deficiency during that period. Five patients were enrolled in the study All received home PN as their sole source of nutrition for at least six months. None of these patients showed clinical manifestations of vitamin deficiency. In addition, compared to daily MVI administration, supplementation with MVI three times per week saved $1,000 per patient per year. This preliminary study raises the question of how much MVI is needed to prevent vitamin deficiency. Using MVI three days a week instead of daily would substantially reduce the cost of treatment and might reduce the risk of infections for these patients.

The influence of retinyl acetate on the postinitiation phase of preneoplastic lung nodules in rats.

The effects of retinyl acetate (RA) on the development of carcinogen-induced metaplastic lung nodules were investigated. Four mg of 3-methylcholanthrene were administered intratracheally to F344 rats maintained on a vitamin A-free diet and receiving 31.4 nmoles of RA per week by intragastric intubation. At 3, 5, and 10 weeks after intratracheal instillation of 3-methylcholanthrene, one group of 24 rats each was started on a weekly dose of 31,400 nmoles of RA; a control group was continued on the low-RA dose. Fifty-two weeks after 3-methylcholanthrene injection, the incidence of metaplastic lung nodules was found to be 3% in the combined high-RA-dose groups as compared with 42% in the low-RA-dose group. It is therefore concluded that RA has a significant effects on the postinitiation phase of preneoplastic lung nodules in rats.

[Changes in vitamins intake in overweight and obese adults after low-energy diets].

UNLABELLED: Dietary modification is indispensable part of obesity treatment. PURPOSE: Assessment of vitamins supply in overweight and obese adults in habitual diet and during consuming a low-energy diet (about 1000 kcal/d). The studied group consisted of 67 women and 29 men, aged 20-68, with BMI above 25 kg/m2. Dietary assessment were carried out by 24-hours dietary recall. Intake of vitamin A, E, B1, B2, C, PP were evaluated. At baseline in men the lowest intake was found for vitamin A-87.6% of RDA, in women for vitamin B1--82.8% of RDA and for vitamin PP--90.2% of RDA, respectively. Low percentage of participants met the requirements for assessed vitamins. After 18 weeks of the low-energy diet the mean supply of assessed nutrients was below RDA. Only in subjects with baseline intake covering the requirement supply of nutrients on the low-energy diet was above the RDA level. Implementation of the low-energy diet can resulted in mean low supply of assessed vitamins. It is necessary to provide information for patients on energy value as well as nutritional value of food products. Subjects need consistent evaluation of realization of the low-energy diet.

[Connection between changing the vitamin and immune status and the character of the throat microflora in patients with chronic tonsillitis].

The author investigated 28 patients with chronic tonsillitis. The fungi sort Candida on the tonsils was discovered at 10 (35.72) patients, the bacterial flora was discovered at the other patients. There were more considerable decrease content of vitamins B2, C, methylnicotinamide and methylmalonic acid in the urine, vitamins B2 and methylnicotinamide in the saliva, vitamins A and B1 in the serum of the blood in the group of the patients with the fungus flora on the tonsils. It was discovered the decrease of numbers of lymphocytes CD8 and level of immunoglobulins G and M, disimmunoglobulinemia in this group. This decrease of the vitamins, cell and humoral immunity level leads to disbacteriosis, decompensation of the disease and development of the complications.
