title: [Induction of monooxygenase system and incorporation of radioactivity from 2-14C-lysine into proteins of rat liver microsomes under the action of phenobarbital and the background of lysine, methionine, threonine and vitamin A, C and E deficiencies].
abstract: The effect of diet on induction of monooxygenases and distribution of radioactivity from 2-14-C-lysine in fractions of liver homogenate, muscle homogenate and blood of male rats treated with phenobarbital (80 mg/kg, three days) was studied. 2-14-C-lysine was injected intraperitoneally 24 h before the first injection of phenobarbital. It was demonstrated that monooxygenase induction, increase of relative liver weight and incorporation of radioactivity from 2-14-C-lysine into fractions of liver homogenate in phenobarbital-treated rats fed diet deficient in lysine, methionine, threonine and vitamins A, C and E were more pronounced as compared with the similarly treated rats which were fed a balanced diet. The possibility of mobilization of deficient essential components to liver from other organs and tissues for maintenance of monooxygenase induction is discussed.
