Abstract
From the hemolytic reaction of cattle erythrocytes sensitized with tuberculin by sera of leprosy patients, it was recognized that leprosy was lower than tuberculosis in positive percentage and serum titer against Levine's report. Namely, in contrast with Takasawa and his coworker's investigations in tuberculosis, it was confirmed that tuberculin was more specific to tuberculosis in hemolytic reaction than leprosy, and there was found no difference of positive percentage between lepromatous and neuro-macular type. Further, the significant relationship between clinical conditions of patients and positive hemolytic reactions was not proved.
The author could not also obtain an expected result in hemolytic reaction using erythrocytes sensitized with each component extracted from leprosy nodules because of a small amount of yields. Considering from the fundamental experiment of hemolytic reaction, however, if more large quantity of the extract of nodules would be obtained, the specific hemolytic reaction would appear in leprosy as in cases of typhoid. Now, this problem will be revealed in future.
