Abstract
In May of 1946 abdominal typhoid injection was given to the pupils of a public school in Hyogo-Prefecture. The. inoculated tuberculosis of human type was present on the injected areas of 102 children.
One of the three persons who gave injections had open tuberculosis and the other two were healthy. Diseased pupils received injection from either one of the three.
All of the tuberculine tests showed positive reactions: —No negative innerter was found among them by the time two years and a half later.
Every 3 to 4 months X-ray photographs were taken and 20 cases with tuberculout change in the lung were discovered.
Small shadows in the lung faded away within a short period of time. Remarkable subjective ymptoms were observed in one case with haematogenic disseminating tuberculosis, and in 'two ca-; es with markcd exudative pleurisy. There were also bone-joint tuberculosis in three ca. ss, and muscle tuberculosis in one case.
Five of the grotip were proved to be tuberculous by expectoration culture.
Except One or two cases, all of them are-studying in the school now, and no death evidently caused from tuberculosis was discovered to date.
