Observations on Leukemia in Wistar and Wistar Furth Rats [PDF]
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. All animals were followed until death and 87 per cent were autopsied. 2. Among 303 autopsied animals there were 403 benign and malignant tumors,

Spontaneous Synovitis in Wistar Rats [PDF]
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. The

Ototoxicity of cypermethrin in Wistar rats
This study presents the effect of cypermethrin on the cochlear function in Wistar rats post-subchronic inhalation exposure. Worldwide several pesticides are described as causing health disorders. Cypermethrin is currently one of the most commonly used, however, little is known about its harmful effects, especially related to hearing. Human studies have

Spontaneous Cholangiofibrosis in a Wistar Rat [PDF]
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 ...

Auricular chondritis in Wistar rats [PDF]
The macroscopic and microscopic features of auricular chondritis in Wistar rats are described. Histologic lesions are characterized by granulomatous inflammation, chondrolysis, and multinodular proliferative foci. The condition in Wistar rats is compared to auricular chondritis in other strains of rats.

Stevia preferences in Wistar rats
The Stevia rebaudiana plant is likely to become a major source of high-potency sweetener for the growing natural-food market. S. rebaudiana is the source of a number of sweet diterpenoid glycosides, but the major sweet constituents are rebaudioside A and stevioside.

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

Abnormal hippocampal melatoninergic system: a potential link between absence epilepsy and depression-like behavior in WAG/Rij rats? [PDF]
Absence epilepsy and depression are comorbid disorders, but the molecular link between the two disorders is unknown. Here, we examined the role of the melatoninergic system in the pathophysiology of spike and wave discharges (SWDs) and depression-like ...

Remodeling Of The Bone Tissue Of Rats Of Different Lines After Melatonin Effect [PDF]
The markers of remodeling of bone tissue (BT) were studied after the impact of pharmacologic dose of melatonin (5 mg/kg of the animal body weight) during 28 days for 3-months rats-males of Wistar and SHR lines.
