摘要：Four hundred twenty-two serum samples from Japanese donors in Aomori and Fukushima Prefectures were tested for Gm (1, 2, 5, 16, 21) and Km(1). The Gm haplo type frequencies estimated were: Gm1, 21 0.450, Gm1, 2, 21 0.161, Gm1, 16 0.291 and Gm1, 5 0.099 in Aomori, and Gm1, 21 0.512, Gm1, 2, 21 0.151, Gm1, 16 0.260 and Gm1, 5 0.078 in Fukushima. The Km1 frequencies for Aomori and Fukushima were estimated at 0.256 and 0.282, respectively. These figures were in agreement with those observed in central and southwestern Japan by previous investigators.
