[DNA damage test in forestomach squamous epithelium of F344 rat following oral administration of ethyl acrylate].
The alkaline elution assay were applied for testing DNA damage of forestomach squamous epithelium in male F344 rat after oral administration of ethyl acrylate (EA), a forestomach carcinogen. The animals were starved for 18 hr and then given a single oral dose of EA. No DNA damage were observed by EA at the concentration of 0.1-4.0%. The weights of the forestomach increased with EA dose, reflecting edema and inflammation, but that of glandular stomach did not change with its dose.
