EROD and GST activities were unchanged. PROD activity increased in animals exposed to the higher dose of the hormone, while BROD was increased after 7 exposure days to both doses of the compound. These results indicate the usefulness of these enzymes as biomarkers for 17 β-estradiol exposure.287-290engERODPRODBROD17 beta-estradiolbiomakerNile tilapiaArtigoAcesso abertoISSN1934-7391-2011-05-04-287-290.pdf6713400866382255320378128967591733520418985842971094988658265940
