Abstract:
We found that in rats exposed to subchronic intoxication with a combination of toxic and mutagenic metals (lead-arsenic-chromium-nickel-cadmium), fluoride and benzo(a)pyrene sorbed on activated charcoal, a bioprophylactic complex (BPC) comprising glutamate, pectin enterosorbent, multivitamin and multimineral preparation and calcium additive, reduced the genotoxic effect. The inclusion into the BPC of a bioactive preparation enriched with polyunsaturated fatty acids (as precursors of intracellularly formed eicosanoids) enhanced the antigenotoxic action. The results of a special survey in a female population were analysed allowing for earlier established populational and individual risk factors for the development of lung, intestinal and breast cancer to form a group of high cancer risk. In this group we selected women who did not have cancer of any type using targeted medical examination. These volunteers were administered a one-month course of a similar BPC. Tests for DNA damage provided positive dynamics only in the group who received the BPC. Generally, the results of the study make it possible to predict the cancer prevention efficacy of the BPC tested.
