Endocardial Schwannomas in the Wistar Rat
Journal of Veterinary Medicine Series A, 2005SummaryEndocardial neoplasms were observed in 13 Wistar rats, 15–30 months old, from a 30‐month inhalation study. Eight of the rats were dissected at 30 months and the other five between 15 and 29 months. Histologically, the lesions in the heart were diagnosed as endocardial schwannomas.

METABOLISM OF MYOSMINE IN WISTAR RATS
Drug Metabolism and Disposition, 2005The alkaloid myosmine is present not only in tobacco products but also in various foods. Myosmine is easily nitrosated, yielding 4-hydroxy-1-(3-pyridyl)-1-butanone (HPB) and the esophageal tobacco carcinogen N'-nitrosonornicotine. Due to its widespread occurrence, investigations on the metabolism and activation of myosmine are needed for risk ...

Spontaneous Immunoglomerulonephritis in Wistar Rats
Pathology - Research and Practice, 1980A strain of rats bred at the Nuclear Study Center of Mol (C.E.N.) develops a nephropathy characterized by granular deposition of immunoglobulin and complement in the renal glomeruli and tubules. We have attempted to specify the complement activation pathways (classical or alternate) in this disease by looking for their initial components (C1q, C3 and ...

Applied Animal Behaviour Science, 2011
The same strain of rats purchased from different suppliers may exhibit behavioral differences that could give rise to variability and deficient repeatability. We have previously demonstrated that outbred Wistar rats from different suppliers display striking differences in voluntary alcohol intake.

A supernumerary forelimb in a Wistar rat
Laboratory Animals, 1987A fifth limb, quite independent of the others, was found in a pup born in our colony of Wistar rats. The malformation is described.

Intra uterine survival and growth of Wistar and Wistar × Brown Norway rat embryos
Theriogenology, 1985Embryos of the Wistar strain and its F(1) cross (Wistar females mated with Brown Norway males) of rats were transferred nonsurgically to 48 Wistar, 17 F(1) cross and 20 Wistar-Imamichi recipients. The two types of embryos were transferred together to each recipient to compare the viability of the embryos. Pregnancy rate was 78.8% (67 85 ). The survival

22Na+ and 86Rb+ Transport in Vascular Smooth Muscle of SHR, Wistar Kyoto, and Wistar Rats
Journal of Cardiovascular Pharmacology, 1988To gain further insight into differences in cellular Na+ and K+ regulation between the spontaneously hypertensive rat (SHR), Wistar Kyoto (WKY), and American Wistar (W) rats, 22Na+ and 86Rb+ washouts were performed under steady-state conditions in cultured vascular smooth muscle cells from the three rat strains.

Spontaneous Neoplasms in Control Wistar Rats
Toxicological Sciences, 1994Neoplastic data on 1370 control Wistar rats from 10 carcinogenicity bioassays done between 1980 and 1990 were reviewed. Mean percentage survival at 104 weeks was 58% for males and 59% for females. A total of 1857 neoplasms were diagnosed in 466 (68%) male and 582 (85%) female rats; 1390 were benign and 467 were malignant (12% with metastasis).

Investigatory behavior of a novel conspecific by Wistar Kyoto, Wistar and Sprague-Dawley rats
Brain Research Bulletin, 2000The assumption was made that investigatory behaviors (i.e., ano-genital and general body sniffing) of a female conspecific by a mature male rat, has positive hedonic characteristics. Because reduced interest in pleasurable events (i.e., anhedonia) is diagnostically related to depressive behavior, the hypothesis was advanced that less investigatory ...
