The generation of t(8;21) was determined in the corresponding umbilical cord blood samples by detection of the AML1-ETO fusion transcripts derived from t(8;21) using nested RT-PCR.     ///    and (ii) the levels for AML1-ETO fusion transcripts resulting from t(8;21) positively correlated with propoxur concentrations in meconium.     ///    Levels for the AML1-ETO fusion transcripts were quantitated by real-time RT-PCR in the t(8;21) positive cord blood samples.     ///    AML1-ETO fusion transcript forms were characterized by RT-PCR amplification and DNA sequencing.
