| dc.description.abstract | It is relevant to develop new monitoring techniques of carcinogenic risk associated to environmental exposition to genotoxic chemicals. The conventional biomonitoring techniques are based on laborious, expensive methods as the ones requiring isolation of lymphocytes from peripheral blood, in vitro cell culture, followed by e.g. cytokinesis-block assay and microscope observation of chromosomal abnormalities. The present work evaluated an infrared spectroscopy method, based on a simple, more economic and high-throughput procedure of analysis of whole blood processed with methanol. It was possible to identify ratios of spectral bands that are statistically different between hospital professionals occupationally exposed to antineoplastic drugs, such as 5-fluorouracil and non-hospital professionals without this exposure. It was also identified ratios of spectral bands which are statistically different between participants presenting lymphocytes with chromosomal abnormalities (as micronucleus, nuclear buds and nucleoplasmatic bridges) and participants not presenting these abnormalities. The infrared spectroscopy-based method presents therefore appealing characteristics to be applied in more intensive and/or large-scale studies of monitoring genotoxic risks. | pt_PT |
