title: [The action of different food factors on the lipid peroxidation processes in the liver microsomes of rats].
abstract: Three series of experiments were conducted to study the effects of varying food factors on lipid peroxidation (LPO) activity in rat liver microsomes. The food rations contained heat-treated sunflower oil, soybean protein isolate, krill protein concentrate. A long-term intake of heat-treated oxidation products was attended by significant activation of LPO in the enzymatic system, by elevation of cytochrome P-450 level, by increased activity of ethylmorphine N-demethylase and aniline n-hydroxylation. The period of half-inactivation of cytochrome P-450 was significantly shortened in NADPH-dependent LPO. The rate of NADPH-dependent LPO was not significantly different in the animals given equal amounts of soybean protein isolate or casein (control). Activation of NADPH-dependent LPO and induction of cytochrome P-450 were recorded in liver microsomes of the animals given krill protein. The high concentration of cytochrome P-450 (in the homogenate and microsomes) correlated with the acceleration of hydroxylation of standard substrates ethylmorphine and aniline.
