چکیده

Neoplastic lesions were observed in untreated aged Sprague Dawley (SD) rats throughout their lifespan starting at 5 weeks. Their mean survival times were 89 to 105 weeks of age. The total tumor incidences were 70 to 76.7% and 87 to 95.8% in males and females, respectively. The common neoplasmas were pituitary adenoma and adrenal pheochromocytoma in both sexes, testicular Leydig cell tumor in males and mammary gland tumors, thyroidal C-cell adenoma and uterine stromal polyp in females.

Historical control background incidence of spontaneous thyroid and parathyroid glands lesions of rats and CD-1 mice used in 104-week carcinogenicity studies

The incidence and range of spontaneous thyroid and parathyroid glands findings were determined in control Han-Wistar and Sprague-Dawley rats, and CD-1 mice from 104-week carcinogenicity studies carried out between 1998 and 2010 at Charles River Edinburgh. In both strains of rats and in CD-1 mice, non-proliferative lesions of the thyroid or parathyroid glands were generally uncommon apart from s...

The aim of this study was to determine the range and incidences of spontaneous microscopic lesions of the pituitary gland in control Han-Wistar and Sprague-Dawley rats and CD-1 mice from 104-week carcinogenicity studies carried out between 1998 and 2010 at Charles River Edinburgh. In both strains of rats and in CD-1 mice, non-proliferative lesions of the pituitary gland were generally uncommon,...

Lifetime Assessment of Dietary Nucleotides Consumption in Sprague-Dawley Rats

To assess the long-term toxicity and carcinogenicity of dietary nucleotides (NTs), Sprague-Dawley rats were administered the NTs for life-through with the dose of 0, 0.01%, 0.04%, 0.16% and 0.64%. With the exception of several groups, the results showed no significant differences in weight gain, clinical symptoms data, blood indicators, and Non-neoplastic lesions frequencies. NTs have dramatica...

Natural Occurrence of Neoplastic Lesions in Young Sprague-Dawley Rats

It is important for the assessment of toxicological effects of chemicals to know what kinds of neoplasms naturally occur in the early life of experimental animals. In the present study, we demonstrated spontaneous neoplasms in Sprague-Dawley rats used in 4-, 13- and 26-week toxicity studies conducted at Bozo Research Center in the last decade. The tumors, which were first observed in 19-week-ol...

Incidence of spontaneous central nervous system tumors in CD-1 mice and Sprague-Dawley, Han-Wistar, and Wistar rats used in carcinogenicity studies.

The incidence and range of spontaneous central nervous system tumors were determined in control Charles River rodents (Sprague-Dawley, Han-Wistar, Wistar rats, and CD-1 mice) from regulatory carcinogenicity studies carried out over the period 2002 to 2013 and were compared with the previously published data. In both species, the brain was notably more affected than the spinal cord. Incidences w...
