Observations on Leukemia in Wistar and Wistar Furth Rats [PDF]
Blood, 1965 Abstract 1. Six-hundred and seventy-three Wistar and W/Fu rats were treated at the age of 4 months with whole body x-ray, orally administered 3MCA or a combination of these agents.

Spontaneous Synovitis in Wistar Rats [PDF]
Toxicologic Pathology, 1998 Spontaneous synovitis has been detected in the stifle joints of control Wistar rats in 4-wk and 2-yr toxicity studies, and a specific site was found to be predisposed to synovitis. The incidence of synovitis was 27.5% for males in the 4-wk study and 40.0% for males and 16.0% for females in the 2-yr study. The severity was not increased with aging.

Spontaneous Cholangiofibrosis in a Wistar Rat [PDF]
Toxicologic Pathology, 2019 In a 2-year carcinogenicity study, we identified a spontaneous cholangiofibrosis in a control male Wistar rat. This lesion has long been considered as a compound-related change, with no spontaneous cases reported in the Wistar rat. In addition to routine hematoxylin and eosin stains evaluation, we applied Masson’s trichrome staining, Alcian blue ...
