Hayes M, Schiefer H
J Environ Pathol Toxicol Oncol . 1990 May; 10(3):103-5. PMID: 2254857
Conventional skin irritation bioassays for trichothecenes are semiquantitative because test animals vary in sensitivity, and the intensity of cutaneous inflammation is poorly correlated with dose. A quantitative bioassay was therefore...
