Abstract

To compare the effect of fenbendazole on the liver and liver microsomal mono-oxygenases of goats, quail and rats, an oral dose of 25 mg/kg was administered to the animals daily for 9 consecutive days. On the tenth day, blood samples and livers were collected from both the control and the treated animals for preparation of serum and microsomes respectively. Determination of the activities of sorbitol dehydrogenase (SDH), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum samples showed that there was no significant increase in the activities of these enzymes in the treated animals as compared to their corresponding controls, suggesting no liver damage. Similarly, no significant difference in the amount of microsomal cytochrome P-450 was found between the control and the treated animals of the same species. Compared to their respective controls, the activities of microsomal benzphetamine N-demethylase and aniline hydroxylase were almost unchanged in the treated goats and rats. However, fenbendazole treatment appeared to enhance the activity of these two microsomal enzymes in quail. The results indicate that fenbendazole is not liver toxic to goats, quail or rats at a dose rate of 25 mg/kg.
