    O Aozasa
    Department of Pharmaceutical Sciences, University of Setsunan, Hirakata, Osaka, Japan
    Bull Environ Contam Toxicol 81:578-82. 2008
    ..However, the DL-PCB concentration was high between 1968 and 1970 in not only the designated Yusho patients but also healthy subjects, and the maximum DL-PCB concentration was close between the two groups...
