The system was initially developed to support the RITA (Registry of Industrial Toxicology Animal-data) project, however, since 1998 it is accessible via the Internet. Besides the nomenclature and diagnostic criteria, RENI contains more than 1,500 histopathological images and for most of the references direct links to the corresponding abstracts in PUBMED are provided.
