N2 - We measured the concentrations of polychlorinated dizenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and non-ortho coplanar polychlorinated biphenyls (non-ortho PCBs) in blood collected from 242 Yusho patients and 74 Yusho-suspected persons in 2004 and 237 Yusho patients and 114 Yusho-suspected persons in 2005. The sums of toxic equivalents (TEQ) concentrations of PCDDs, PCDFs, and non-ortho PCBs in the blood of Yusho patients in 2004 and 2005 were 126.1 and 124.2 pg TEQ/g lipid, respectively, and the concentrations were 3.4 and 3.3 times higher than those of normal controls that had been previously reported, respectively. Those of the Yusho-suspected persons were about 0.8 and 1.0 times higher than those of normal controls, respectively. Although the TEQ concentrations of PCDDs and non-ortho PCBs among Yusho patients, Yusho-suspected persons, and normal controls were nearly the same, the PCDFs levels of Yusho patients were about 9.8 and 9.5 times higher than those of normal controls in 2004 and 2005, respectively. The concentration of 2,3,4,7,8-pentachlorodibenzofuran (2,3,4,7,8-PeCDF), which was the highest among PCDFs congeners for Yusho patients, was about 10. 6 and 10.2 times higher than that of the normal controls in 2004 and 2005, respectively. In the case of Yusho-suspected persons, the concentrations were 0.9 and 1.4 times higher than those of normal controls, respectively. However, some of the Yusho-suspected persons showed a high concentration of 2,3,4,7,8-PeCDF that was approximately 15 times greater than concentrations in normal controls. Of 74 Yusho-suspected persons measured in 2004, 7 persons were officially registered as Yusho patients based on the "New Diagnostic Criteria" that officially became the diagnostic criteria for Yusho exposure on September 29, 2004, which included a concentration of 2,3,4,7,8-PeCDF in the blood, and in 2005, 14 persons of 114 Yusho-suspected persons were officially registered as Yusho patients.
