| Abstract |
|
I conducted the Tuberculin Reaction 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 injecting both liquids: the negative rate by A. 66.3土 2.11%
Showed double figue than that by B, 31.5 土 2. 27% but the positive rate by B, 46.4土 2.22%
appeared much higher and intenser in its reaction than that by A, 29. 3土2. 03.
2) As the result of looking into the reaction intensities by both, in 48 hours after the infection; the sam 191 cases(38. 0+2.17%) the higher in A. 6 cases(. 3%) the higher in B. 305 cases(6.08土2. 17%). It appeared that the intensity by B is more than A.
3) As the result or observing the freqllency in appearance of induration, blister and necrosis made by both it appeared that those by E are more than by A.
4) As the result of comparison with the reaction intensities by both, in 24 or 48 hours after the injection; there was reaction intensities by both, in 24 or 48 hours after the injection; .there was notited no considerable difference between those of 18h>24h and 24h>4Sh in A. however, in B, those of 24h>48h are fairly more than those of 48h>24h after the intensity.
5) In 24 and also 48 hours, the cases showing B> A in the reaction inbeasity held the absolut majority among the tested.
6) As the result of observing the reaccions 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 the tested.
Considering the above facts, it would be understandable that both liquids have much differences with each other in their subcutaneous reactions. lt would bring about some confusion in clinical test, mass survey or picking up of objects for B. C. G. vaccination. Therefore. I would liké to emphasize that the above facts must be considered significantly in the public health fleld. |
