[Biochemical bases of prevention of the cytotoxic effect of xenobiotics].

Possible sources of cytotoxicity of xenobiotics and main mechanisms of realization of their damaging effect are briefly considered. Protective system of a cell is characterized with regard for the peculiarities essential for development of principles of alimentary prophylaxis of cytotoxic effects of foreign compounds. Modern approaches to alimentary modification of the processes of biotransformation of xenobiotics and promotion of protective capacities of a cell are discussed.
