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