I conducted the Tuberculin Reactio Survey for 605 children of primary schools by
using two different kinds of Tubekulin and I found considerable differences between the
subcutaneous reactions by both liquids. By the way, my reading of the reactions was
done by Toda´s method.
1) As the result of reading the reactions in 48 hours after injecting both liquids : the
negative rate by A. 66.3±2.11% Showed double figue than that by B, 31.5±2.27%, but
the positive rate by B. 46.4±2.22%, appeared much higher and intenser in its reaction
than that by A, 29.3±2.03.
2) As the result of looking into the reaction intensities by both, in 48 hours after the
injection
the same. 191 cases(33.0 2.17%)
the higher in A. 6 cases(.3%)
the higher in B.
305 cases (6.08 2.17%)
It appeased that the intensity by B is more than A.
3) As the result of observing than frequently in appearance of induration, blister and
necrosis made by both; it appeared that by B are more than by A.
4) As the result of comparison with the reaction with the reaction intensities by both,
in 24 or 48 hours after than injection; there was reaction intensities by both, in 24 or 48
hours after the injection: there was notited no considerable difference between those of
48h>24h and 24h>48h in A, however, in B, those of 24h>48h are fairly more than those
of 48h>24h after the intensity.
5) I n 24 and also 48 hours, the cases showing B>A in the reaction inbeasity held
the absolute majority among the tested.
6) As the result of observing the reactions by both liquids. shown following changes
of the times, 24 48, 72, or 96 hours; it appeared that the non-changed in their
intensities, 495 cases held the majority among tested.
Considering the above facts, it would be unberstadable that liquids have much
difference with each other in thier subcutaneous reactions. It would baling about some
confusion in clinical test, mass survey or picking up of objects for B. C. G. vaccination
Therefore I would like to emphasize that the above facts must be considered
significantly in the public health field.
