Atlas of Histology of the Juvenile Rat should be of interest to toxicologic pathologists, toxicologists, and other biological scientists who are interested in the histomorphology of juvenile rats. For several decades the laboratory rat has been used extensively in nonclinical toxicology studies designed to detect potential human toxicity of drugs, agrochemicals, industrial chemicals, and environmental hazards. These studies traditionally have involved young adult rats that are 8-10 weeks of age as studies are started. It is becoming increasingly apparent that children and young animals may have different responses to drug/chemical exposures, therefore, regulatory agencies are emphasizing toxicology studies in juvenile animals. While the histologic features of organs from young adult and aged laboratory rats are well known, less is known about the histologic features of organs from juvenile rats. Final histologic maturity of many organs is achieved postnatally, thus immature histologic features must be distinguished from chemical- or drug-related effects. While this postnatal organ development is known to exist as a general concept, detailed information regarding postnatal histologic development is not readily available. The Atlas includes organs that are typically sampled in nonclinical toxicology studies and presents the histologic features at weekly intervals, starting at birth and extending through postnatal day 42. Written and edited by highly experienced, board-certified toxicologic pathologistsIncludes more than 700 high-resolution microscopic images from organs that are typically examined in safety assessment toxicology studiesDetailed figure legends and chapter narratives present the salient features of each organ at each time intervalFigures are available for further study via Elsevier's Virtual Microscope, which allows viewing of microscopic images at higher magnificationValuable resource for toxicologic pathologists who are confronted with interpretation of lesions in juvenile rats in situations where age-matched concurrent controls are not available for comparison, e.g., with unscheduled decedents INDICE: Integumentary System, Including Mammary and Adnexal Glands Lauren Staska Musculoskeletal System Jairo Nunes Nervous System, Central and Peripheral Amera Remick Respiratory System Melanie Greeley Gastrointestinal System Gary Coleman Liver, Exocrine Pancreas and Salivary Glands Danielle Brown Reproductive System, Female Catherine Picut Reproductive System, Male Catherine Picut Endocrine System Amera Remick Immune System George Parker Hematopoietic System Josely Figuieredo Special Senses (Eye and Ear) Gary Marit Urinary System Danielle Brown Cardiovascular System Melanie Greeley
