On the Biochemical Racial-Index of the Japanese in the Hokuriku District (Northern Part of Middle Japan)

摘要

In 1919 L. and H. Hirschfeld (30) studied a number of soldiers belonging to the Allied Armies in Macedonia, and showed that agglutinogen A predominates greatly over agglutinogen B in the population of northern Europe, and that agglutinogen B predominates in Asia and Africa.Finding a remarkable difference in the percentage distribution of the blood groups in the different races, they classified the races in three types examined on the basis of what they called the “Biochemical Racial-Index,” that is the ratio of the percentage of A to the percentage of B or , in the population.![Figure][1]/img![Figure][1]/imgThose races, having a racial-index of more than 2, were called of “European Type,” and those with an index less than 1, of “Asio-African Type,” and those from 2.0 to 1 of “Intermediate Type.” Since the work of Hirschfeld, a large amount of additional information has accumulated in several countries.
