Mortality and Neoplastic Lesions in Untreated Sprague-Dawley Rats
Data on tumour types and frequencies of rodent species obtained from longevity studies can be helpful tools for the interpretation of carcinogenicity studies, since conclusions concerning carcinogenicity of a particular substance require the knowledge of incidences of naturally occuring neoplasms of the animals under study. In the present paper a report is given on the mortality and the most important neoplastic lesions of untreated Han: SPRD rats kept in a life-span study from weaning to their natural death.
