Desert sheep experimentally or naturally infected with Fasciola gigantica were used to study the influence of infection on the activities of some drug-metabolizing enzymes found in the liver. The enzymes investigated were aminopyrine N-demethylase, aniline 4-hydroxylase and UDP-glucuronyltransferase. The experimental infection was confirmed histologically by detection of Fasciola eggs in faeces and by measuring the activities of sorbitol dehydrogenase (SD), glutamate dehydrogenase (GD) and aspartate aminotransferase (AST) in plasma during the course of the disease. Liver specimens from naturally infected sheep were obtained from the slaughter house. The activities of aminopyrine N-demethylase and aniline 4-hydroxylase were significantly decreased in sheep either naturally infected or during the acute stage of experimental fascioliasis (killed 5 weeks post-infection). The activity of UDP-glucuronyltransferase was decreased in naturally infected sheep and those killed 9 or 13 weeks post-experimental infection.

The effects of oral administration of different doses of the latex of Calotropis procera on the activities of drug-metabolizing enzymes in the liver, kidneys and duodenal mucosa of Nubian goats were investigated. Lesions and changes in total plasma protein concentration and in the activities of plasma sorbitol dehydrogenase (SD), glutamate dehydrogenase (GD) and aspartate aminotransferase (AST) were studied. The daily oral administration of the latex at dose rates of 0.4 and 0.8 ml per kg for 7 days resulted in a significant inhibition of the activity of aniline 4-hydroxylase. No signfiicant effects on the activities of aminopyrine N-demethylase and UDP-glucuronyltransferase were observed. A single oral dose of 1.2 or 1.6 ml per kg killed goats within 7 h and resulted in increased activities of aminopyrine N-demethylase and aniline 4-hydroxylase. UDP-glucuronyltransferase was found to be insensitive to tissue injury induced by the latex of C. procera. There were no pathological changes in goats given 10 mg per kg of dieldrin alone or in those pretreated with dieldrin and given the latex at a dose rate of 1.2 ml per kg 14 days later. Dieldrin pretreatment resulted in the induction of the activities of drug-metabolizing enzymes in the liver, kidneys and duodenal mucosa and it may have protected goats from the lethal effects of the latex.

Berenil (4,4-diamidinodiazoaminobenzene-diacetamide acetate) or Suramin [sodium salt of 8-(3-benzamido-4-methylbenzamido)-naphthalene-1,3,5-trisulfonic acid] treatment of rats infected with Trypanosoma b. brucei enhanced hepatic microsomal aniline hydroxylase and p-aminopyrine N-demethylase activities. While Suramin inhibited significantly the activities of cytoplasmic glutamate dehydrogenase and lactate dehydrogenase, Berenil had no effect. The kinetic profiles of these enzymes consistently showed a Km value similar to that of controls. Both cytosolic and microsomal glutathione-S transferase and microsomal epoxide hydratase were unaffected by Suramin. However, a significant increase in cytosolic glutathione-S transferase was observed with Berenil. Microsomal phospholipids were not affected by any of the drugs.

The effect of oral administration of praziquantel at different dose levels on the activities of metabolizing hepatic enzymes (aminopyrine N-demethylase, aniline 4-hydroxylase and UDP-glucuronyltransferase) was studied in healthy locally bred rabbits. The pathological changes resulting from drug's toxicity were assessed histologically, by measurement of total plasma protein concentration and of the activities of the plasma enzymes sorbitol dehydrogenase (SD), glutamate dehydrogenase (GD) and aspartate aminotransferase (AST). No significant changes were obtained after praziquantel administration at dose levels of 40 and 800 mg/kg body weight, whereas 1600 mg/kg and 2000 mg/kg of praziquantel resulted in a significant decrease in the activities of the three drug-metabolizing hepatic enzymes under investigation in the livers of treated rabbits. All rabbits which received praziquantel at the dose rate of 2000 mg/kg died 10-20 hours following praziquantel treatment.
