The metabolism of foreign compounds in the cestode, Moniezia expansa, and the nematode, Ascaris lumbricoides var suum. 1975

P G Douch, and S S Blair

1. The ability of the cestode Moniezia expansa and the nematode Ascaris lumbricoides var suum to metabolize foreign compounds has been assessed. 2. Both species were unable to oxidase aldrin, aniline, biphenyl, butylbenzene and nitrobenzene or to demethylate aminopyrine, and 4-nitroanisole. 3. M. expansa and A. lumbricoides var suum readily induced 4-nitroanisole, nitrobenzene, 4-nitrobenzoic acid and 4-nitrophenol to the corresponding amines. Azobenzene, dimethylaminoazobenzene, and 1,2-dimethyl-4-(4-carboxyphenylazo)-5-hydroxybenzene were also reduced. 4. Hydrolysis of esters, acetanilide, acetylsalicylic acid, aryl sulphates and aryl phosphates took place readily. However, beta-glucuronides were not hydrolysed. 5. The following reactions were not detected in either species: phosphate, sulphate, beta-glucuronide or beta-glycoside conjugation of phenolic compounds; acetylation of amino compounds, or the formation of glycine conjugates with 4-aminobenzoic acid or benzoic acid. 6. Male nematodes showed a higher rate of drug metabolism than female nematodes.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D009579	Nitrobenzoates	Benzoic acid or benzoic acid esters substituted with one or more nitro groups.	Nitrobenzoic Acids,Acids, Nitrobenzoic
D010084	Oxidation-Reduction	A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).	Redox,Oxidation Reduction
D010636	Phenols	Benzene derivatives that include one or more hydroxyl groups attached to the ring structure.
