In 1968, the contamination of cooking oil by heat-degraded polychlorinated biphenyls (PCBs) caused a case of mass poisoning, the so-called Yusho incident. The cause of Yusho disease is thought to be i...ngested toxic substances, including not only PCBs but polychlorinated dibenzofuran (PCDFs) in Kanemi rice oil. Extensive studies have been performed since 1995 by the Yusho study group involving follow-up surveys of human blood concentrations of the casual compounds in Yusho patients as well as clinical trials of the acceleration of the excretion of these compounds in Yusho patients. We have previously measured dioxin concentrations in the blood of 649 Yusho patients in annual medical examinations from 2001 to 2009. We determined that the concentrations of 2,3,4,7, 8-PeCDF 1,2,3,4,7,8-HxCDF 1,2,3,6,7,8-HxCDF, and 3,3',4,4',5,5'-HxCB (#169) in the blood of Yusho patients were more than twice as high levels to as those of normal controls. In this study, we compared the concentrations of 2,3,4,7,8-PeCDF, 1,2,3,4,7,8-HxCDF, 1,2,3,6,7, 8-HxCDF, and 3,3',4,4',5,5'-HxCB (#169) in the blood of male Yusho patients with those of female Yusho patients. As a result, it was found that the mean concentrations of 2,3,4,7,8-PeCDF 1,2,3,4, 7,8-HxCDF 1,2,3,6,7,8-HxCDF, and 3,3',4,4',5,5'-HxCB (#169) in female Yusho patients were 2.9, 3.7, 2.4, and 1.3 times higher, respectively, than those of male Yusho patients.続きを見る
