Isohemagglutination: The Work of Jan Janský with a Critical Analysis

[摘要] 1. 1. Janský's classification is based upon 3160 “cross-agglutinations” in which he utilized sera from 30 (32) individuals and corpuscles from 99.2. 2. These “cross-agglutinations” are reproduced from his work, appearing herein as table 1.3. 3. A more orderly arrangement of his “cross-agglutinations” has been made by me and appears as table 2.4. 4. Janský's classification is based upon the 30 (32) individuals whose sera he used in the “cross-agglutinations.” This is reproduced as table 3 and shows: Group I, 12 individuals; Group II, 10; Group III, 6; and Group IV, 2.5. 5. In table 4, I have given the result of my analysis of his series of “cross-agglutinations.” It is evident that Janský failed to realize that, in addition to grouping the sera that he was using in his work, he was also grouping the other individuals whose corpuscles only he employed. This is clearly shown in table 2. Consequently his results should have been Group I, 40 individuals; Group II, 38; Group III, 20; and Group IV, 2; with a racial index of 1.8.6. 7. It seems more logical to me to assume that the irregularity shown by the blood of individual 7524 F. B. is due to a low isoagglutinin “b” titer which has been made ineffective by dilution, very short incubation period and possibly temperature of incubation. This is contrary to the interpretation of Guthrie and Huck (15).7. 8. The blood of individual 7627 Š. J. is exceptional. However, due to the fact that Janský did not include the serum of this individual's blood in his series, one is hardly justified in drawing any definite conclusions regarding it.
