A Communicating Intestinal Duplication in a Sprague-Dawley Rat [PDF]

Toxicologic Pathology, 1998
Duplications of the gastrointestinal tract arc exceedingly rare in laboratory animals. We report a case of a communicating intestinal duplication in a 17-wk-old Sprague-Dawley (SD) rat. The duplication was present in the mesenteric border of the ileum, and both proximal and distal ends were communicated with the lumen of ileum.

Improved timed-mating, non-invasive method using fewer unproven female rats with pregnancy validation via early body mass increases [PDF]

, 2018
For studies requiring accurate conception-timing, reliable, efficient methods of detecting oestrus reduce time and costs, whilst improving welfare. Standard methods use vaginal cytology to stage cycle, and breeders are paired–up using approximately five ...

Splenic Hemangiosarcoma in a Young Sprague-Dawley Rat

Journal of Toxicologic Pathology, 2012
The present report describes a rare case of spontaneous hemangiosarcoma in a nine-week-old male Sprague-Dawley rat. At necropsy, multiple white nodules of various sizes were observed on and within the enlarged spleen and liver and were histopathologically determined to be composed of spindle- to oval-shaped cells that showed invasive growth without ...

Spontaneous Iron Overload in Sprague-Dawley Rats [PDF]

Toxicologic Pathology, 1997
In a review of the toxicological studies performed in our laboratory during the period 1986-1995, we occasionally observed significant iron overloading in the liver. Liver tissue was examined by light and electron microscopy, and the results were analyzed by sex and age (7, 9, 11, 19, 31, 59, and 111 wk).
