Figure 4From: Speciation of arsenic trioxide metabolites in peripheral blood and bone marrow from an acute promyelocytic leukemia patientProfiles of concentrations of arsenic species in BM plasma collected during the remission induction therapy. BM aspirates were collected before the treatment start (day -1), and 14, 28, 42, and 56 days after the start of administration. The concentrations of arsenic species in plasma were determined with HPLC/ICP-MS as described in "Patient and Methods." Similar to Figure 3 (A), identification of arsenic species by a spike test was conducted using a plasma sample collected on day 14 and was shown in Figure 4 (A). The concentrations of arsenic species calculated from these chromatograms are shown in Figure 4 (B). (●): As(V); (■): As(III); (▲): MA(V); (♦): DMA(V); (O): AB.Back to article page
