Hydroxylated polychlorinated biphenyls (OH-PCBs) are formed as major metabolites of PCBs by cytochrome P450 enzyme-mediated oxidation. It has been reported that their total concentration in serum samples of Yusho patients ranged from 390 to 1300 pg/g. We measured the concentration of OH-PCBs in blood collected from 183 Yusho patients living in Japan in 2010. The major OH-PCB metabolites were 4-OH-CB187 (ND-1300 pg/g-wet), 4-OH-CB146 + 3-OH-CB153 (8.4-1200 pg/g-wet), 4-OH-CB109 (ND-530 pg/g-wet) and 4'-OH-CB172 (ND-380 pg/g-wet). The total OH-PCBs ranged from 36 to 3800 pg/g-wet. A positive relationship between the concentrations of OH-PCBs and PCBs was observed, but no significant relationship between the concentrations of OH-PCBs and PCDD/DFs was observed.
羟基化多氯联苯(OH-PCBs)是多氯联苯经细胞色素P450酶介导氧化形成的主要代谢产物。据报道,油症患者血清样本中它们的总浓度在390至1300 pg/g之间。我们测定了2010年从居住在日本的183名油症患者采集的血液中OH-PCBs的浓度。主要的OH-PCB代谢产物为4-OH-CB187(未检出-1300 pg/g湿重)、4-OH-CB146 + 3-OH-CB153(8.4-1200 pg/g湿重)、4-OH-CB109(未检出-530 pg/g湿重)和4'-OH-CB172(未检出-380 pg/g湿重)。OH-PCBs的总浓度在36至3800 pg/g湿重之间。观察到OH-PCBs浓度与多氯联苯浓度之间呈正相关,但未观察到OH-PCBs浓度与多氯二苯并对二噁英/多氯二苯并呋喃(PCDD/DFs)浓度之间存在显著相关性。
