Refinement of long-term toxicity and carcinogenesis studies()	2004-09-27		.txt	text/plain	4465	227	44	journal: Fundam Appl Toxicol We must continue to strive to find species and strains that can metabolize chemicals similar to humans, are small enough to be housed in large numbers, and have low prevalence of spontaneous lesions with sufficient life span to express the toxic and carcinogenic potential of chemicals. We must continue to strive to find species and strains that can metabolize chemicals similar to humans, are small enough to be housed in large numbers, and have low prevalence of spontaneous lesions with sufficient life span to express the toxic and carcinogenic potential of chemicals. However, viral infections were associated with nonneoplastic lesions in lungs, nasal cavity, liver, and other organs of rats and mice and may complicate the identification and interpretation of toxic effects of chemicals (NTP, unpublished data).	./cache/cord-311260-eyvaazfj.txt	./txt/cord-311260-eyvaazfj.txt
