WebJul 23, 2010 · Toxicokinetic studies should preferably be carried out in the same species as that used in other toxicological studies performed with the substance (normally the rat, a minimum of 4 animals of one sex for each dose). Initial estimation of absorption can be achieved by mass balance determination, but further investigations such as intravenous ... WebAlso, toxicokinetic information can be used to evaluate if a NM behaves differently from a similar NM or bulk material with the same chemical composition, e.g. with regard to barrier penetration. As for all studies with NMs, a proper characterization of the NM dispersions or aerosols used in the toxicokinetic studies is essential.
WebJan 21, 2003 · Toxicokinetics is the generation of kinetic data to assess systemic exposure, either as an integral component of preclinical toxicity studies, or in specially designed supportive studies. These data help to understand the relationship between observed toxicity and administered dose. WebJun 28, 2024 · TK studies are typically performed with unlabeled (no radioactivity) chemical/substance. Data from the ADME studies are generally used to determine the analytes to be monitored in TK studies using validated analytical methods such as gas chromatography- and liquid-chromatography-mass spectrometry.
WebThis study applied multi-mycotoxin liquid chromatography with tandem mass spectrometric detection (LC-MS/MS) methods to determine the biomarkers of exposure in urine and serum samples from a dose-response study with pigs. The 24 studied pigs were divided into three groups: a control and two experimental ones (with different levels of feed contamination). …
