STP Position Paper: Interpreting the Significance of Increased Alveolar Macrophages in Rodents Following Inhalation of Pharmaceutical Materials

Nonneoplastic Lesion Atlas—The National Toxicology Program (NTP) has created a new web-based resource containing thousands of high quality images and guidelines for diagnosis of nonneoplastic lesions in experimental rodent models. The first nine sections are now available the NTP website. When completed, the Atlas will contain 56 sections, each focusing on a particular organ or tissue.

Announcing INHAND Nomenclature Change Control
The INHAND Project (International Harmonization of Nomenclature and Diagnostic Criteria for Lesions) is a joint initiative of the STP, ESTP, BSTP and JSTP to develop an internationally-accepted nomenclature for proliferative and non-proliferative lesions in laboratory animals. The INHAND nomenclature is being adopted by the US FDA for use in the SEND initiative (Standard for the Exchange of Nonclinical Data). Pathologists who discover a lesion in a toxicity study that is not covered by the INHAND nomenclature are encouraged to request a new INHAND term. In addition, changes, additions, and updates to current terms may be desirable and may be requested.
