摘要：Since the establishment of the National Toxicology Program (NTP), there have been gradual changes in strategies to evaluate the overall toxicity of chemicals as well as their carcinogenic potential.

This paper describes the scientific rationale and experimental processes used by NTP in designing studies. Also, an outline of current NTP protocols are given for prechronic and chronic toxicity/carcinogenicity studies. Full text Full text is available as a scanned copy of the original print version.
