Summary:We analyzed the severity grades of the skin symptoms of Yusho patients who visited the annual examinations in 1997 and 1998. The severity grades of the skin symptoms clearly improved. The patients graded as 0 I-II increased and those graded as II III-III decreased as compared to the data in 1993 and 1994. The skin severity scores did not change much, although the patients who showed 0 or 1 reached more than 60% in both 1997 and 1998. The blood PCB concentration of Yusho patients also clearly decreased, especially in the patients who showed "A" pattern.
