Investigations on metabolism of zearalenone in broilers

Mycotoxin Research, 2000
Two experiments were carried out with male broilers to examine excretion kinetics of zearalenone (ZEA) and its metabolites (Exp. 1) and their occurrence in blood plasma and bile fluid (Exp.2) after a single oral dose of ZEA (approximately 6 µg/kg body weight) from naturally contaminated wheat.

Metabolism of zearalenone by Fusarium Roseum

Journal of Toxicology and Environmental Health, 1977
Twenty products associated with the metabolism of zearalenone by Fusarium roseum were analyzed with respect to time and culture conditions. By statistical analysis a set of six metabolites possibly related to zearalenone were selected. These products were characterized by gas chromatography--mass spectrometry and other methods.

Zearalenone as an endocrine disruptor in humans

Environmental Toxicology and Pharmacology, 2016
Zearalenone (ZEA), a fungal mycotoxin, is present in a wide range of human foods. Many animal studies have found ZEA to possess a disruptive effect on the hormonal balance, mainly due to its similarity to naturally-occurring estrogens. With increasing consciousness of the adverse effects of endocrine disruptors on human health, it is becoming more ...

Determination of zearalenone and ochratoxin A in soil

Analytical and Bioanalytical Chemistry, 2003
Mycotoxins are secondary metabolites, formed by the action of fungi on agricultural crops in the field or during storage. These metabolites are highly toxic to animals and humans and high levels have been measured in agricultural crops. In order to evaluate human risks due to ingestion of mycotoxin-contaminated food different methods have been ...

Physiologically Based Pharmacokinetics of Zearalenone

Journal of Toxicology and Environmental Health, Part A, 2009
The objectives of this study were to (1) develop physiologically based pharmacokinetic (PBPK) models for zearalenone following intravenous (i.v.) and oral (p.o.) dosing in rats and (2) predict concentrations in humans via interspecies scaling. The model for i.v.

Metabolism of Zearalenone in Rat Liver

Acta Pharmacologica et Toxicologica, 1978
Abstract The metabolism of zearalenone in rat liver has been investigated. The studies were performed mainly with liver homogenate, though isolated microsomes and hepatocytes have also been used. Zearalenone was metabolized along two principal pathways, conjugation with glucuronic acid, which was the main route and reduction to an isomer of zearalenol.

Effect of zearalenone on dairy cows

American Journal of Veterinary Research, 1986
SUMMARY Doses of 99% pure zearalenone (0.0, 31.25, 62.5, 125.0, 250.0, or 500.0 mg) in gelatin capsules were given once a day per os to 18 nonpregnant, nonlactating, multiparous dairy cows for 2 consecutive estrous cycles. There was no effect (P < 0.10) on serum progesterone concentrations, rbc, wbc, pcv, hemoglobin, and estrous cycle length ...

[Biotransformation of zearalenone].

Wei sheng wu xue bao = Acta microbiologica Sinica, 1992
The conversion of Zearalenone by some strains of microorganisms was investigated. When the selective strains of Rhodotorula sp., Arthrobacter sp., Saccharomyces sp., and Candida sp. were incubated by shaking or standing at 28 degrees C for 72 h with an alcoholic solution of Zearalenone as the substrate at a concentration of 2-10 mg/ml ethanol (50-100 ...
