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. 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]
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.

Ototoxicity of cypermethrin in Wistar rats
Brazilian Journal of Otorhinolaryngology, 2020 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]
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 ...

Auricular chondritis in Wistar rats [PDF]
Laboratory Animals, 1990 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.

Parathyroid Gland Carcinoma in a Wistar Rat [PDF]
Veterinary Pathology, 2003 An anaplastic carcinoma was found in one of the two parathyroids of a 2-year-old male Wistar rat, which was sacrificed at the end of a carcinogenicity study. Morphologically, it was characterized by the presence of nodular areas of pleomorphic and dense cells with numerous atypical mitoses and large regions of smaller and dark monomorphic cells devoid

Spontaneous Teratoma in a Wistar Rat
Experimental Animals, 1983 A spontaneous tumor was found in the left adrenal gland of a 35-day-old male Wistar rat. Histologically, the tumor consisted of various tissues derived from all three embryonic germ layers, i.e. the ectoderm (nervous tissue and skin), mesoderm (striated muscle, bone and cartilage), and endoderm (glandular tissue).

Dopamine depletion in wistar rats with epilepsy
Brazilian Journal of BiologyAbstract The dopamine content in cerebral structures has been related to neuronal excitability and several approaches have been used to study this phenomenon during seizure vulnerability period. In the present work, we describe the effects of dopamine depletion after the administration of 6-hidroxidopamine (6-OHDA) into the substantia nigra pars ...
