Characterization of the hepatic microsomal mixed-function oxidase enzyme system in miniature pigs.
Hepatic microsomal protein, cytochrome P-450, UDP-glucuronyltransferase, ethylmorphine demethylase, aniline hydroxylase, and aryl hydrocarbon hydroxylase levels were measured in the 2-, 4-, 5-, 6-, and 8-month-old Hanford miniature pig. The activities or concentrations of all of the liver parameters measured had apparently reached their adult plateau level by 2 months of age. The use of the miniature pig in toxicology research programs is discussed.
