biomarkers of cellular reaction to pesticide exposure in a rural population.in the present study we report data obtained from the evaluation of subjects occupationally exposed to pesticide mixtures from santa fe province, argentina, using biomarkers for butyrylcholinesterase (bche) and acetylcholinesterase (ache) activities, catalase (cat), lipid peroxidation (by tbars assay) and the damage index comet assay (dica). our results showed an ache inhibition (25% and 15% in directly and indirectly groups, respectively) in relation to controls with no significant modification ...201019811113
baseline values of micronuclei and comet assay in the lizard tupinambis merianae (teiidae, squamata).the micronucleus test (mn) and comet assay (ca) are currently the most widely used methods that allow the characterization of dna damage induced by physical and chemical agents in wild species. the continuous expansion of the cultivated areas in argentina, since the introduction of transgenic crops, mainly soy, in association with the increased use of pesticides, transformed deeply the natural environments where the lizard tupinambis merianae (tegu lizard) occurs. despite the fact that reptiles ...201222902164
