Abstract
Abstract The effects of rafoxanide (RFX), nitroscanate (NSC) and mebendazole (MBZ) on oxidative pathways in whole F. hepatica maintained in a simple salt solution have been examined. The anthelmintics did not alter glucose uptake or glycogen mobilization. NSC and RFX depressed ATP and increased AMP levels. MBZ behaved similarly at first, but later depressed the total adenine nucleotides. All three drugs influenced end product formation, increasing it initially, although by different mechanisms. With NSC, early increases in lactate and acetate excretion were later abolished. With RFX, there was an initial increased production of acetate and propionate. Later, excretion of propionate was reduced and that of succinate was increased. MBZ also increased succinate excretion, but to a much greater extent. In addition, it inhibited lactate production. A number of effects of the drugs on the internal concentrations of metabolic intermediates are described. The mechanisms of action of the drugs are discussed.
