Experiments were performed to determine whether the activity of hepatic drug-metabolizing enzymes could be estimated in intact livers by 13C NMR spectroscopy. 13C-labelled aminopyrine was administered to isolated perfused mouse livers and the rate of decline in the NMR signal arising from the drug was used to estimate the half-life of aminopyrine. The technique was sufficiently sensitive to discriminate between the enzyme activities in normal livers and in livers whose enzyme activity was enhanced by treatment with sodium phenobarbitone. It was also demonstrated that demethylation of aminopyrine was not impaired in perfused livers from mice infected with Plasmodium berghei. |
