Effect of vitamin therapy on sensitivity of peripheral blood lymphocytes to clastogenic effect of mutagens in vitro.

Spontaneous and in vitro induced (with 0.01 and 0.1 mg/ml dioxidine and 0.1 and 1.0 U/ml bleomycin) chromosome aberrations were counted in cultured peripheral blood cells from 11 donors before and after 2-week therapy with a vitamin complex. The complex contained the major vitamins in doses not surpassing the recommended daily doses. Vitamins had no effect on spontaneous mutations, but increased cell resistance to clastogenic effects of dioxidine in a concentration of 0.1, but not 0.01 mg/ml. Cell sensitivity to bleomycin notably increased after vitamin therapy in some donors and decreased in others, the mean parameters in the group remained virtually unchanged.

[Effects of biologically active food additives with different contents of vitamins on the vitamin status in humans].

The comparative study of influence of two biologically active food additives with the different contents of vitamins is carried out: a drink "Zolotoi Shar", the dose of vitamins in which makes 50-90% from recommended daily consumption, and "Vitabalance 2000", the contents of vitamins in which at 2-17 of time exceeds need of organism. The use of both additives within 3 weeks resulted in increase of levels of vitamins C, A, E, B2, B6 and carotenoids in blood serum. However if in case of consumption of a drink an authentic level was reached only for vitamin C and beta-carotene, in a case "Vitabalance 2000" for all investigated vitamins except vitamin A. Thus, if the consumption of a drink has lowered frequency of deficiency of 3-4 vitamins, but has not allowed to liquidate it completely, in case of "Vitabalance 2000" consumption the simultaneous deficiency 3-4 vitamins. The received data allow to believe the biologically active food additives containing vitamins in amounts exceeding recommended consumption, are convenient for fast liquidation of hypovitaminoses, and the preparations containing vitamins in doses making 30-50% from need of organism, are acceptable for daily filling of insufficient consumption of vitamins with a usual diet for a long time.
