Sugar-Induced Hypertension in Sprague-Dawley Rats
American Journal of Hypertension, 1991Male Sprague-Dawley rats were fed either conventional rat chow, or a diet in which vegetable starch was replaced with either glucose or sucrose for two weeks. At the end of this period, measurements were made of weight, blood pressure, and plasma glucose, insulin, and triglyceride concentrations.

Spontaneous brain tumours in Sprague-Dawley rats
Food and Chemical Toxicology, 1986Data were collected over a 5-yr period on brain tumours occurring spontaneously among Sprague-Dawley-derived rats in the HRC laboratories. Gliomas, like meningiomas, tended to occur more among males than in females, and in general appeared to be lesions of older rats. Astrocytic tumours of rats were less differentiated than those in man.

Ozone uptake in awake Sprague-Dawley rats
Toxicology and Applied Pharmacology, 1987Knowledge of ozone (O3) uptake in rats in integral to efforts to quantitatively extrapolate animal data to man. We have measured percentage O3 uptake in 30 adult Sprague-Dawley rats exposed, nose only, for 1 hr to 0.3, 0.6, or 1.0 ppm O3. Tidal volume and breathing rate measurements, obtained by plethysmography, were time-matched with changes in ...

Pup attraction to lactating Sprague-Dawley rats
Behavioral Biology, 1976Pup attraction to lactating Sprague-Dawley rats was demonstrated in an olfactory discrimination apparatus with own pups and with standard test pups, i.e., 20 day-old pups who had never been in physical contact with the adult experimental animals. Pup attraction was observed from Day 8 to Day 26 postpartum.

Inherited tertiary hypothyroidism in Sprague–Dawley rats
Brain Research, 2007Thyroid hormones (THs) are important in the development and maturation of the central nervous system (CNS). The significant actions of THs during CNS development occur at the time when TH levels are lower than those in the mother and the hypothalamic-thyroid (HPT) axis is not fully functional.

Normal colon of Sprague-Dawley rats
Anatomy and Embryology, 1992The patterns of expression of the human-tumor-associated antigens, CO17-1A, GA73-3, BR55-2, GICA19-9, CA50 and carcino-embryonic antigen (CEA) were studied in the normal colonic mucosa (the last three also in the serum) of Sprague-Dawley rats. Four immunohistochemically different segments were identified: caecum, ascending colon, transverse colon and ...

Callosal oligodendrocyte number in postpartum Sprague-Dawley rats
Brain Research, 2009Prolactin (PRL), an anterior pituitary hormone with neurogenic properties associated with pregnancy, has been implicated in oligodendrocyte proliferation during gestation, contributing to increased myelination in the maternal brain. However, PRL is elevated during lactation as well, suggesting that the postpartum (PP) period may contribute to ...

Carcinogenicity of 4-chloronitrosopiperidine in Sprague-Dawley rats
Zeitschrift f�r Krebsforschung und Klinische Onkologie, 19784-Chloronitrosopiperidine was administered to a group of 15 male Sprague-Dawley rats as a 0.005% solution in drinking water for 27 weeks. Of the 15 animals, 12 died with tumors induced by the treatment, half of them by the 41 st week; all 15 were dead at 58 weeks.

KIDNEY TRANSPLANTS IN CYCLOSPORINE-TREATED SPRAGUE-DAWLEY RATS
Transplantation, 1990Previous studies by others have shown that transplanted rat kidneys have abnormally low clearances of paraaminohippuric acid, inulin, and creatinine, due to rejection and/or to warm-ischemia-induced injury. In the present studies, randomly bred Sprague-Dawley rats were used as donors and recipients.
