It is known that inflammatory cytokines, which level is significantly increased in the pathogenesis of multiple sclerosis (MS), as well as interferon-beta, which is used to treat autoimmune diseases, can inhibit cytochrome P450-dependent processes of detoxification and biotransformation. The uncontrolled decrease of the activity of these processes may have a negative affect on the state of patients, so it is urgent to study the functional state of the cytochrome P450 system and to develop effective means for its regulation in these conditions. The effect of vitamin D3 and efficiency of its composition with vitamins B1, B2, B6, PP, E, alpha-lipoic, alpha-linolenoic acid and mineral substances (Mg, Zn, Se) in prevention of a functional state changes of cytochrome P450- and b5-dependent systems of the rat brain and liver endoplasmic reticulum at EAE are investigated. It has been shown that the essential decrease of the level of these cytochromes is observed both in the brain and liver. In addition the level of activity of NADH- and NADPH-oxidoreductases, which are part of microsomal electron transport chain components and coupled with monooxigenases, was reduced. These changes confirm the disturbances of a redox state and functional activity of detoxication and biotransformation systems in the studied animal tissues. Supplement of vitamin D3 as well as the composition of biologically active substances, which we developed earlier, effectively eliminated the decrease of the level of cytochromes and activities of NADH-oxidoreductase in immunised rat tissues. Normalization of these disturbances can be explained by antioxidant and membrane-stabilizing properties of applied substances, and also by the ability to reduce the activity of inflammatory reactions by regulation of the level of inflammatory cytokines in rat organism at EAE. Thus the studied vitamin-mineral composition appeared to be more effective to normalize the found disturbances and it can be useful for prevention of exacerbations and for improvement of a status of patients with multiple sclerosis and other diseases, which are accompanied with hyperactivation of immune system.
