History
Favism is a disorder characterized by hemolytic anemia in response to ingestion of fava beans. Favism as a diagnosis has been known since antiquity. One theory for the Pythagoreans' avoidance of beans is avoidance of favism, but more likely, this was a philosophical matter, such as the belief that beans and humans were created from the same material.
The modern understanding of the condition began with the analysis of patients who exhibited sensitivity to primaquine. The discovery of G6PD deficiency relied heavily upon the testing of prisoner volunteers at Illinois State Penitentiary, although today such studies cannot be performed. When some prisoners were given the drug primaquine, some developed hemolytic anemia but others did not. After studying the mechanism through Cr51 testing, it was conclusively shown that the hemolytic effect of primaquine was due to an intrinsic defect of erythrocytes.

Famous quotes containing the word history:
“To summarize the contentions of this paper then. Firstly, the phrase the meaning of a word is a spurious phrase. Secondly and consequently, a re-examination is needed of phrases like the two which I discuss, being a part of the meaning of and having the same meaning. On these matters, dogmatists require prodding: although history indeed suggests that it may sometimes be better to let sleeping dogmatists lie.”
