Mucositis is a major oncological problem. The entire gastrointestinal and genitourinary tract and also other mucosal surfaces can be affected in recipients of radiotherapy, and/or chemotherapy. Major progress has been made in recent years in understanding the mechanisms of oral and small intestinal mucositis, which appears to be more prominent than colonic damage. This progress is largely due to the development of representative laboratory animal models of mucositis. This review focuses on the development and establishment of the Dark Agouti rat mammary adenocarcinoma model by the Mucositis Research Group of the University of Adelaide over the past 20 years to characterize the mechanisms underlying methotrexate-, 5-fluorouracil-, and irinotecan-induced mucositis. It also aims to summarize the results from studies using different animal model systems to identify new molecular and cellular markers of mucositis.

Background: Studies in experimental animals revealed that acute and chronic treatment with small-molecule immunosuppressive drugs lead to neurobehavioral alterations in rodents.
Methods: Against this background, this study investigated behavioral alterations in rats after repeated administration of FTY720, an immunosuppressive drug used for the treatment of multiple sclerosis, employing the open field, elevated plus maze, and dark/light tests.
Results: Compared to controls, repeated FTY720 treatment affected behavior in rats, reflected by a reduction in distance traveled as well as increased time engaged in freezing in the open field and elevated plus maze.

The anti-inflammatory/immunomodulatory effects of L. (TM), a plant distributed in the Mediterranean region, have been insufficiently examined. The effects of the TM ethanol extract were tested in a rat collagen-induced arthritis (CIA) model of rheumatoid arthritis.

Rat strains differ in physiology, behavior, and recovery after central nervous system injury. To assess these differences, we compared the gross and local anatomy and neuromorphology of the lumbar spinal cord of the Wistar and Dark Agouti (DA) strains. The key findings include (i) distinct spatial relationships between vertebrae and spinal segments in the two strains; (ii) Wistar rats have larger volumes of spinal cord gray and white matter; (iii) DA rats have smaller total neuronal populations, thus indicating an expectation of smaller local neuronal populations; (iv) this expectation was confirmed for interneurons expressing calbindin 28 kDa.
