1. Induction of the drug-metabolising enzyme systems is a major cause of clinically relevant drug interactions. The potential of a drug to engage in such interactions may be assessed in in vitro systems such as precision-cut tissue slices. %26lt;br%26gt;2. Precision-cut tissue slices have a number of important advantages compared with the use of cells in culture, especially when tissues with a heterogeneous cellular population are concerned. %26lt;br%26gt;3. Extensive studies concerned with the induction of cytochrome P450 and Phase II enzymes in precision-cut tissue slices from various animal and human tissues, such as liver, lung and intestine, using established inducing agents have revealed that slices mimic the in vivo situation. %26lt;br%26gt;4. Precision-cut tissue slices is a reliable, informative and cost-effective technique for assessing the potential of chemicals to up-regulate drug-metabolising enzyme systems.
