摘要

The Syrian hamster embryo (SHE) assay (pH 6.7) is an in vitro candidate to replace in vivoncarcinogenicity tests. However, the conventional method of visual scoring of foci (non-transformed vs.ntransformed colonies) can be time-consuming and is open to subjectivity. Infrared (IR) spectroscopynhas the potential to provide objective assessment of such SHE colonies with the added advantage ofnpotentially providing mechanistic information. In this study, SHE cells were treated with one of eightndifferent chemical regimens, allowed in culture to attach and form foci on IR-reflective glass slides;nthese were subsequently interrogated by attenuated total reflection (ATR) Fourier-transform IRn(FTIR) spectroscopy. Derived mid-IR spectra (n ?13 406) were subjected to chemometric analysisnfocusing primarily on the extraction of biochemical information related to test agent treatment and/ornmorphological transformation. The use of ATR-FTIR spectroscopy with chemometrics to analyze thenSHE assay is a novel approach to toxicological assessment.
