Trouble shooting in toxicopathology.
Toxicopathology, also referred to as toxicologic pathology, can be defined as the study of structural and functional changes in cells, tissues, and organs that are induced by toxicants (such as drugs, industrial and agricultural chemicals), toxins (chemicals of biological origin such as mycotoxins and phycotoxins), and physical agents (such as heat and radiation); the investigation of the mechanisms by which these changes are induced; and the development of risk assessment and risk management policies based on such information. Toxicologic pathology primarily deals with the morphologic or structural effects of the toxicant and the mechanism by which this structural effect is induced. This article highlights some of the problems that toxicologic pathologists may encounter in obtaining and interpreting pathology lesions. By alerting toxicologists to some of these issues, it is hoped that a better understanding of the use and limitations of toxicologic pathology data will occur.
